Technology, science, and math

No flu

I would never say that there was any such thing as a silver lining to the COVID pandemic, but it is true that basically nobody died from the flu this year because of masking and social distancing.

What medical officials worried would be a “twindemic” at the end of last year — the concurrence of influenza and COVID-19 sicknesses overwhelming Houston’s hospitals — turned out surprisingly well.

At Memorial Hermann, just three patients tested positive for influenza during the 2020-2021 flu season, compared to 983 patients during the 2019-2020 flu season. Doctors test for both flu and COVID-19 as a precaution.

The same public health measures that prevent SARS-CoV-2 from spreading — masks, social distancing and regular hand-washing — kept influenza strains from sickening people.

“When we were looking internally, we just weren’t seeing flu,” said Dr. James McCarthy, chief executive physician at Memorial Hermann.

Flu infections are down nationwide, with a hospitalization rate of 0.7 per 100,000 people, according to the Centers for Disease Control and Prevention. During the last flu season, the rate was nearly 100 times higher — 66.1 per 100,000 patients. Pediatric deaths also decreased, from 189 last year to one this year.

[…]

Researchers wondered whether being infected with the coronavirus would wipe out the chances of getting the flu, and say it may be a factor that contributed equally to declining flu rates.

“Part of it is because we had a worse virus that was spreading faster,” McCarthy said.

Knowing to wear masks and get a flu vaccine could be a huge step toward eradicating deadly flu seasons. But will people continue to practice those public health measures? Doctors don’t know.

“We’re recognizing that not only can we protect our friends and loved ones from COVID, but we can also do it from influenza with precautions for medically vulnerable folks,” McCarthy said.

I’ve gotten a flu shot every year for as long as I can remember, and as far as I know I’ve never gotten the flu. I will certainly continue to get those vaccines as before, and I’d strongly consider wearing a mask during the flu season going forward when doing things like grocery shopping. Hard to see any reason why not to at this point.

First look at the 2021 hurricane season

Yeah, it’s getting to be that time of year. From Space City Weather:

Good morning. The most reputable hurricane season forecasting service, led by Phil Klotzbach at Colorado State University, has released its first outlook for the 2021 Atlantic season. The forecast calls for above normal activity (see table below) with 17 named storms instead of the more typical 12; eight hurricanes instead of six; and about 50 percent total more activity, in terms of the duration and intensity of tropical systems, as measured by accumulated cyclone energy.

This outlook is consistent with other predictions, already released, in calling for a busier than normal season. What I like about Klotzbach’s forecast is that he’s very clear about his methodology—using a combination of statistical modeling, and historical correlations between Spring-time weather conditions and hurricane activity later in the year. Klotzbach also has a reasonable track record.

With that said, seasonal hurricane forecasts are far from perfect. I think, generally, we can expect a busier Atlantic season, but we’re almost certainly not going to see a brute of a year like 2020. Moreover, the chance of the Houston area being directly affected by serious tropical weather (in terms of floods, winds, or surge) is pretty low. Historically, the region only sees a significant storm about once a decade or so. Therefore, while it certainly is time to begin planning for the 2021 Atlantic season, I very much do not want you to start worrying or obsessing about it. Matt and I will, of course, be here every step of the way, and we’ll be releasing a new app before the June 1 beginning of the season to keep you informed.

“Not as bad as 2020” is a low bar to clear, but we have to start somewhere. There will be other forecasts, and that will give us a fuller picture of what is expected. Also of importance is predicting the development and path and severity of hurricanes and big rainstorms, and towards that end the NOAA rolled out a new model last month.

“You just get a better forecast,” said Lance Wood, a meteorologist with the National Weather Service’s Houston/Galveston office. “The day-to-day reliability of the model forecasting would be better, though it would probably be more noticeable in something like an extreme rainfall threat.”

The upgrades include a variety of changes. For one, the Global Forecast System (an atmospheric model) can now interact with a global wave model. Running these models together will extend wave forecasts to 16 days, up from the current 10-day forecasts. This is particularly helpful to mariners planning long-distance voyages, Wood said.

The upgrades also provide a more detailed look at the atmosphere at various vertical levels. Previously, the model showed data at 64 different levels in the atmosphere. Now, it will show 127 different levels. This type of information can help provide more accurate cloud coverage forecasts — a weather outlook that’s often requested by general aviation pilots who want to know how thick the clouds will be.

And finally, the new-and-improved Global Forecast System will be able to pull more data from satellites that provide weather observations and planes that measure wind, temperature and moisture, Wood said.

In other words, we’ll have more time in advance of a hurricane to know that it’s coming and to prep for it. We need all the help we can get with that. Stay alert, be prepared, don’t panic, and we’ll get through this.

What to expect when you’re fully vaccinated

The CDC has released some guidance that will help people understand what is safe to do and what precautions they will still need to take once they are fully vaccinated.

Fully vaccinated Americans can gather with other vaccinated people indoors without wearing a mask or social distancing, according to long-awaited guidance from federal health officials.

The recommendations also say that vaccinated people can come together in the same way — in a single household — with people considered at low-risk for severe disease, such as in the case of vaccinated grandparents visiting healthy children and grandchildren.

The Centers for Disease Control and Prevention announced the guidance Monday.

The guidance is designed to address a growing demand, as more adults have been getting vaccinated and wondering if it gives them greater freedom to visit family members, travel, or do other things like they did before the COVID-19 pandemic swept the world last year.

“With more and more people vaccinated each day, we are starting to turn a corner,” said CDC Director Dr. Rochelle Walensky.

During a press briefing Monday, she called the guidance a “first step” toward restoring normalcy in how people come together. She said more activities would be ok’d for vaccinated individuals once caseloads and deaths decline, more Americans are vaccinated, and as more science emerges on the ability of those who have been vaccinated to get and spread the virus.

You can see their guidance here. Among other things, this should make a lot of grandparents happy:

A lot more people will get those vaccines in the coming weeks. The need for continued mask-wearing is simply because you can still get and carry the SARS-CoV2 virus after being vaccinated, you are just much less likely to become sick if you do. Basically, you can still be an asymptomatic carrier, and so for the safety of the not-yet-vaccinated, especially in public places, your mask is still needed at this time. But that will eventually decrease, as the vaccination numbers swell. We just had to wait a little longer. We can and must still do the right thing in the meantime. Vox, the Chron, and Daily Kos have more.

Memorial Hermann CEO begs for Abbott to reconsider maskless mandate

He won’t listen, but maybe some of the people who would have stopped wearing their masks will.

On March 2, Gov. Greg Abbott announced the issuance of a new executive order, which “re-opens” Texas. The new order, which takes effect Wednesday, March 10, also terminates the statewide mask mandate.

As a health system, we respect the governor and recognize that he has an incredibly difficult job right now; however, we disagree with the terms and the timing of this new order, and strongly encourage him to reconsider this decision.

[…]

Additionally, we are deeply concerned about the timing of this decision, especially as we have just learned that all of the major new COVID-19 variants, which seem to be more dangerous and more transmissible, have now been identified in Houston; in fact, we are the first major U.S. city to confirm that all of these new variants are active in our community. Even more, for the first time in many weeks, the number of new cases reported around the world is higher than it was a week ago. Finally, we are gravely concerned that upcoming Spring Break gatherings will result in surges similar to those caused by holiday get-togethers, or worse.

The pandemic is not over, and our safety measures should not be, either. We hope that by continuing to practice the proven safety measures and encouraging others to do so as well — and as more and more people in the greater Houston area become vaccinated — we can happily support lifting masking restrictions in the future, maybe even as soon as several months from now. But we feel that issuing this order at this time, considering the current environment, is premature. In the greater Houston area, it is clear that COVID-19 is not yet under community control.

You may think this is not particularly remarkable, but hospital bigwigs have tried very hard to stay out of political fights surrounding COVID:

And as for that mention about COVID variants in Houston, consider this:

Read that whole thread and maybe be a little scared. Definitely keep your mask on, and stay away from any business or other indoor location that doesn’t require masks. If we truly are on our own, we’ve got to take this a lot more seriously than Greg Abbott does.

Let me Google that vaccine locator for you

Good.

In the coming weeks, Google will begin implementing a vaccine locator service on its platforms for Texans to use, including appointment details, clinic hours and more.

The rollout comes as part of a $150 million plan announced by Google in late January for vaccine education and accessibility. Included in this plan are vaccination site location services for Texas, Arizona, Louisiana and Mississippi, as well as plans to open vaccination sites as needed.

“Searches for ‘vaccines near me’ have increased 5x since the beginning of the year and we want to make sure we’re providing locally relevant answers,” Google CEO Sundar Pichai said in a release.

Information for the vaccination locator will be pulled from government agencies, pharmacies and VaccineFinder.org to provide users with detailed assistance.

The plan also includes grants distributed to public health agencies and organizations assisting marginalized individuals with vaccine access.

You can read the full release here. This does seem like the simplest answer to the problem, but it did need for there to be consistent data out there about where to find vaccines in the first place. Now you won’t have to know where to look for that, you can just search as you normally do. Or at least you will in the coming weeks. That should help a lot.

Here comes the vaccine

Houston’s first doses have arrived.

Months of waiting for a COVID-19 vaccine to arrive in Houston are almost — but not quite — over, as hospitals prepare to move the first doses from sealed subzero shipments and into the arms of thousands of front-line health care workers this week.

About 19,500 doses of Pfizer’s vaccine will arrive Monday at four medical centers in Texas: MD Anderson Cancer Center in Houston, Methodist Dallas Medical Center, Wellness 360 at UT Health San Antonio and UT Health Austin’s Dell Medical School, according to the Texas Department of State Health Services, which is overseeing deliveries of the first vaccine approved and shipped in the United States.

Another 75,075 doses will arrive at 19 additional sites on Tuesday, including seven in the Houston area. By midweek, 27 hospitals in the Houston region, most of them Texas Medical Center hospital system flagships or suburban campuses, will have received doses.

Officials on Sunday at some Houston hospitals compared it to waiting on an Amazon delivery: The package is confirmed, but the email with the tracking number and details hasn’t arrived. The first inoculations in Houston could happen in days, depending on when those shipments appear, said Dr. Marc Boom, president of Houston Methodist.

“If it arrives tomorrow, we will have a full day of vaccinations on Tuesday,” Boom said Sunday. “If it’s Tuesday, depending on what time, we could have some people come in. … I have people scheduled literally in five-minute slots.”

[…]

Under a tiered plan developed by public health leaders, the first vaccine doses will be given to front-line hospital workers. Later shipments will allow hospitals to administer doses to patients at high risk of contracting COVID-19 and developing serious complications, likely in January.

And after that it gets trickier. And it could get even trickier still.

Here are some basic outlines of what’s happening. As we learned last week the Trump White House skimped on actually buying enough doses of vaccine from Pfizer. But the federal government will cover the actual purchase of vaccines. The White House says the military is in charge of and has a plan to actual get the supplies to the states. And though we don’t know all the details let’s assume they have that covered. But that only appears to be getting the crates of supplies to a central staging point in each state. That’s not a negligible job. But it’s only a relatively small part of actually getting the country vaccinated. You need public health campaigns. You need staging areas and distribution from wherever the military drops it off to actual health centers and vaccination centers around each state. And finally you need a small army of medical professionals to actually administer the doses. It’s a big job and the Trump administration hasn’t funded any of that or devised any national plan.

In the absence of any federal plan or budget the CDC and HHS have cannibalized existing budgets to get some money to states for planning. But the sums are by most estimates an order of magnitude less than the amount needed.

State governments would be hard pressed to fund an operation like that during the best of times. But states and local governments around the country are already pushing massive cuts because of the dislocations caused by the pandemic. Through much of the latter part of 2020 the assumption was that this would be dealt with in a follow-up stimulus plan. But of course that never happened.

What the White House has arranged funding for is a critical but relatively small part of the vaccination effort: vaccinations for people in assisted living facilities and health care workers. Those are the two most critical populations. They should go first, and the plan is to get those people vaccinated in December and January. But that leaves the great bulk of the population unvaccinated. The plan is for that phase to end around Feb 1. Meanwhile CARES Act funding, which states can use for various purposes, has to be spent by Dec. 31.

That’s all that’s funded. It’s like a trap door set up for Biden to fall through. So as you can see, today’s excitement and anticipation over the vaccine is cued up to turn sharply to disappointment in February when people start asking where their shots are and blame the train wreck on President Biden. No plan. And no funding to implement a plan. Of course that is potentially catastrophic in human terms. But a lag in vaccination means not only more suffering and death but more delay in allowing the economy to get back on its feet, since people aren’t going to go to restaurants and participate in public life until case numbers drop dramatically.

That…would be bad. I suppose as long as there are still talks for another COVID relief bill, or if Dems win both Georgia Senate runoffs, we still have hope. But yeah, that could be a problem.

Also a problem:

The White House Coronavirus Task Force is increasingly suggesting that states including Texas begin shutting down again, saying in reports sent to state leaders this month that they aren’t doing enough to slow the worst surge in COVID cases that the country has seen.

“This surge is the most rapid increase in cases; the widest spread of intense transmission, with more than 2,000 counties in COVID red zones; and the longest duration of rapid increase, now entering its 8th week, that we have experienced,” say the reports, sent to Texas and other states on Dec. 6. “Despite the severity of this surge and the threat to hospital systems, many state and local governments are not implementing the same mitigation policies that stemmed the tide of the summer surge; that must happen now.”

Texas, the report says, “must increase mitigation to prevent ongoing community spread,” including “significant reduction in capacity or closure of public and private indoor spaces, including restaurants and bars.”

The task force’s reports over the last several weeks, meanwhile, have consistently pointed to the success of European countries — many of which have shuttered restaurants, bars and other businesses — in stemming the outbreak.

“The majority of the United States is not mitigating similarly,” Dec. 6 state report says.

You know how I feel about this. Do your best to take care of yourself, because Greg Abbott isn’t going to do anything to help you. The Trib has more.

The COVID breathalyzer test

Sounds promising.

Texas A&M researchers and a Dallas artificial intelligence company are developing a rapid COVID-19 test that would use a breathalyzer, rather than a swab, and potentially make it safer to hold large gatherings.

The testing device, housed in a kiosk that can fit in the back of an SUV, could be set up outside of large group settings such as schools, churches and corporate offices.

People would step up to the device and, with a disposable straw, blow into a copper hole on the front of the kiosk.

The system captures the user’s breath and analyzes it for compounds that a body generates when it’s fighting SARS-CoV-2, the virus that causes COVID-19. Users would receive the results within a minute of the test through a mobile app.

“It’s all about establishing a controlled environment where people can interact and have confidence about it,” said Rob Gorham, executive director of SecureAmerica Institute, a network of public institutions and private manufacturing and technology companies based at Texas A&M. “It can create more normalcy around establishing these trusted group settings, whether it be an airplane or a football stadium.”

The device, called Worlds Protect, is a collaboration between Texas A&M researchers, who developed the hardware for the testing systems, and Worlds Inc., which developed the artificial intelligence software.

Here’s a story on Texas A&M’s website about the development. They’re waiting for FDA approval, and could start manufacturing the devices as soon as March. The devices cost about $5,000, and each test costs less than fifty cents, so it would be reasonably cost effective for, say, a pro sports team or stadium to buy a few and use them as a prerequisite for attending a live event. I would hope that the test is aggressive about flagging questionable results – the default should be “go get yourself a real test”, so that there are essentially no false positives. Better to turn away a hundred COVID-free people than to let one COVID-positive person in the door. If this fulfills its promise, it’s a big step in the direction of returning to “normal”.

“COVID-killing machines”

I like the sound of that.

The George R. Brown Convention Center was built to hold Houston’s biggest crowds, but during the pandemic its halls have grown quieter. In reviving the center, Houston First squared off with a problem facing all local venues — showing the public they’re safe.

To address the problem, the local government corporation created to operate the city’s convention and performing arts facilities launched a public education campaign in August and spent about $30,000 on three mobile air filtration units for the convention center’s general assembly space, which is often used by businesses for presentations. The units, installed in September, add a layer of security for guests, said Michael Heckman, the group’s acting president and chief executive.

“Any level of added confidence that we can give to the public during this time is incredibly important,” Heckman said. “And I think once people understand the level of sophistication of this technology they’d be highly impressed, as we were.”

The filters are the product of Houston’s Integrated Viral Protection, an enterprise formed by engineer and real estate developer Monzer Hourani based on technology developed by researchers at the University of Houston.

[…]

Other pandemic-era inventions, such as UV light devices, require people to leave the room and, while they kill viruses on surfaces, they are not as effective at treating the air, Hourani said. Most HEPA, or high-efficiency particulate air filters, remove particles through holes still big enough to let coronavirus through, he said.

Despite the creation, Hourani said people gathering still need to wear masks. From a clinical perspective, air filtration devices like IVP’s can be used as an added layer of protection in addition to other preventative measures, said Dr. Jill Weatherhead, assistant professor of infectious disease for Baylor College of Medicine.

“At this point it’s unclear how much benefit it provides,” she said, “and it shouldn’t take the place of mask-wearing and social distancing. And frequent disinfecting.”

Most of what’s in between is technical details about the filters and the company, which you can peruse as you see fit. I think the idea of “making it safer for people to congregate indoors, as long as they wear masks” is a good one, and if it works would allow for a greater resumption of normal activities, without increasing the risk. It’s pretty clear that there are a lot of people who can’t or won’t do the risk-mitigating things we need them to do – and let’s be clear, some of these folks are service and retail workers who have no choice, while some others very much could be making different decisions – and as long as that is the case, the next best thing we can do is improve the odds overall. I hope this works as intended.

A new way to deliver rural Internet access

Pretty cool.

From his 500-acre spread in Paige, just 50 miles east of Austin, Francisco Artes can send an email, check a website or two and conduct a chat session.

But there are some days when streaming video or participating in a teleconference is out of the question. Like a lot of folks with homes and businesses in rural America, Artes struggles with his internet connection – and really, he’s lucky to have one at all.

“We get maybe 1 (megabits per second) uploads, maybe 10-12 (Mbps) downloads,” he said. “It’s really hit or miss whether you’ll have a good Zoom call.”

Artes’ primary internet service uses a form of WiFi, beamed to an 80-foot tower on his land, where he operates a winery and a festival site. He’s supposed to be getting 25 Mbps for both downloads and upload.

Help may soon be on the way. Artes is testing a new kind of internet service being developed by a Houston startup called Skylark Wireless. It turns the unused frequencies normally associated with television stations into internet service, and it’s seen as a real possibility to get high-speed data service to people in rural areas who’ve had to do without for decades.

Known as TV white space technology, or TVWS, it already has sold Artes, who is now able to join those Zoom teleconferences without missing a beat.

“We’ve gotten speeds that at times were mind-boggling for out here in the country,” Artes said, adding he’s getting 30 megabits a second for both download and upload speeds. “We can’t wait we can start using it commercially.”

That could happen as soon as the end of this year or early next, say Skylark co-founders Ryan Guerra and Clayton Shepard. The company, which will license its technology to rural internet service providers, already has customers lined up to deploy it.

[…]

While other companies are using TVWS to do rural broadband internet access, Skylark’s approach is unique. It uses software-enabled radios that can be programmed to run on different frequencies, making the tech less expensive to configure and change as conditions and customer needs warrant.

Guerra, the CEO, and Shepard, the chief technical officer, say the same signals used for television are perfect for getting internet access to people in out-of-the-way places.

“The low frequencies in TV that are occupied by television broadcasters allow (the signal) to go much further and propagate through trees, buildings, materials, very well compared to other bands,” Guerra said. “In rural areas, the main challenge is to provide connectivity to people that are spread so far apart and in such difficult terrain. You have all the same challenges that television broadcasting has already solved: Getting through trees, going long distances, etc.”

That makes the signals that TV uses so valuable that they are referred to as “beachfront spectrum.” The Federal Communications Commission has allowed it to be used for data when it’s not being used for television, for the express purpose of solving the problem of getting internet access to rural areas.

In a city the size of Houston, there are literally dozens of television stations operating on many different channels. But out in the country, there may be only a few that can be received by TVs in any given area. The other channels go unused, which is why they are referred to as “TV white space.”

For example, Shepard said that Francisco Artes’ test setup is receiving internet service on what would normally be channels 53 or 58. Those channels are actually licensed for use in the area, but currently are not occupied. With permission from the holder of the frequencies – in this case, Lowell Feldman, a Skylark investor and CEO of wireless service provider Evolve Cellular – the startup is allowed to test on them.

True “white spaces” are frequencies that are unlicensed, and when Skylark Wireless goes commercial, it will be moving the technology to use those bands. That requires an FCC certification.

There’s more, so read the rest. Skylark is a Houston company with connections to Rice University. As the story notes, there are 21 million Americans (or more, depending on how you do the estimate) that lack broadband Internet access. This approach solves a lot of the technological challenges, which in turn should make it cost-effective. The big cellular companies are looking at this space as well, so perhaps there will be a viable solution soon. Given the need for remote learning and e-commerce these days, that can’t happen soon enough.

Mutant mosquito update

Keeping you informed on the news you can really use.

Four years ago, the Zika virus became an issue. More than 300 people were infected in Texas. Zika can cause birth defects and fetal neurodevelopmental abnormalities in pregnant women.

The vector is Aedes (rhymes with ladies) aegypti and Aedes albopictus mosquitoes. The Aedes mosquitoes transmit Zika, chikungunya, dengue and yellow fever, which prompted state and county health officials to discuss actionable solutions to control the mosquito.

Talks about releasing genetically modified mosquitoes in Houston began in 2018 between Harris County and Oxitec, a United Kingdom-based company that produces sustainable technologies or transgenic methodologies to stem the impact of disease-spreading insects. Talk also began about a similar action in Monroe County, Fla.

However, ecological concerns have been raised about the use of these mosquitoes.

“We had stakeholders there who wanted to use it,” said Kevin Gorman, head of field operations at Oxitec. “We had vector control authorities who were keen to try the technology.”

The Environmental Protection Agency stated in a May 2020 press release that it approved an experimental use permit to Oxitec to field-test its genetically engineered mosquito in the United States.

The genetically modified Aedes aegypti mosquitoes are males that mate with wild female Aedes aegypti, essentially causing the offspring to die before they can reproduce due to a genetic variation.

Oxitec had two successful years of controlling the Aedes aegypti in Brazil with its current generation of mosquito and had several years of efficacy in Brazil with its first-generation, Gorman said.

[…]

A release in Florida seems imminent, but not in Texas. Despite an established relationship and much communication, it looks like the Florida Keys will be going solo.

“Although we really enjoyed a sort of really great relationship with Houston at the moment we’re in a holding pattern with Houston,” Gorman said. “And we’re unlikely to be releasing there, and there certainly aren’t firm plans to do so in the next year.”

He cited uncertainty due to personnel changes in the county government as the reason for the decision.

A statement sent to Reform Austin by Sam Bissett, a communications specialist with Harris County Public Health, said the choice to not move forward with the release was made last year by both parties.

“At this time, there are no agreements or approval in place for Harris County to work with Oxitec in 2021. While we have had discussions with Oxitec previously about a potential partnership with Harris County Public Health, those discussions were paused last year between both sides.”

See here for my previous post on Oxitec and mutant mosquitoes, from 2017. There’s a lot more to the story and it’s hard to just capture the essence of it, so go read the whole thing. Apparently, the Aedes aegypti mosquito is more abundant in the Rio Grnade Valley than in Harris County, so maybe we’re not the best place to test this out in the US. Harris County also employs mosquito traps and dragonfly armies to control the local skeeter population. Which all seems a whole lot more quaint these days, but Zike and its ilk haven’t gone away just because we’re mostly inside these days. We will be spending more time outside again, and when we do we’d like to not be at significant risk from some other emergent deadly disease, thank you very much. Maybe next time we’ll be able to work something out.

Our vaccination rates are down, too

I wish I had a snappy intro for this, but I just don’t.

The summer months are typically the busiest of the year in Dr. Kenya Parks’ office, a steady flow of parents trotting in their little ones to receive immunizations required for school attendance.

But the numbers are way down this year, one more casualty of the COVID-19 pandemic.

“It’s quite noticeable,” said Parks, a pediatrician with UTHealth and UT Physicians, the practice of doctors at the University of Texas’ McGovern Medical School in Houston. “Parents who usually pack our offices around now instead are putting off or canceling or just not showing up for appointments. They’re scared.”

Such fear is a primary reason for an average 44 percent drop in the number of doses administered in the Texas Vaccines for Children program during the early months of the pandemic, according to a new state report. The trend puts Texas at risk of vaccine-preventable disease outbreaks, a potential disaster when school starts up.

The drop is particularly high for immunizations for measles — 55 percent — the highly infectious disease declared eradicated in the United States 20 years ago but now experiencing a resurgence. The drop in doses administered is slightly higher in the Houston area, site of a measles outbreak in 2019 and identified in a study the same year as one of the nation’s hot spots, vulnerable to an even bigger outbreak.

The overall Texas trend is concerning because the state’s vaccination rates were bad even before the pandemic. The state last year failed to meet minimal national goals for eight of 11 immunizations and barely squeaked by for the three it did meet.

“It’s like we got an F in eight classes and a D- in three, and now things are getting worse, when we can least afford it,” said Allison Winnike, president of the Immunization Partnership, a Houston-based vaccine advocacy organization. “That’s why it’s crucial parents call their pediatricians, get their kids in for their vaccinations if they’re not up to date.”

The good news, if you want to call it that, is that this doesn’t seem to be the result of changing attitudes about vaccinations. It’s about fear of the virus, which is something we can be a bit more hopeful will change in the not-too-distant future. But this is also a real risk factor for reopening schools, which I haven’t seen any official acknowledgement of. Risking a COVID-19 outbreak to force in-person school at a predetermined date is bad enough. Risking a measles outbreak on top of that is even worse. You can blame the parents if you want for the decisions they’ve made – I for one would be more compassionate, but you do you – but that doesn’t change the fact that this is a thing that will need to be dealt with, and that’s likely going to require some time. Are Greg Abbott and the TEA even thinking about this?

We need to understand what we did wrong

So yeah, we need this.

Two of the nation’s most influential experts on the coronavirus pandemic, both based in Texas, are calling for an independent, nonpartisan investigation of the U.S. response to the novel coronavirus.

“We must prevent this from happening again,” said Gerald Parker, who directs the pandemic and biosecurity program at Texas A&M’s Bush School of Public Service. “This is not going to be our last pandemic.”

Peter Hotez, a Houston-based vaccine researcher and frequent commentator on cable news, noted that the current virus, SARS-CoV-2, is the third coronavirus to pose a major health threat in the last 20 years. And given that outbreaks had already wreaked havoc in China and Europe, U.S. public health systems were notably slow to respond.

“What hurt Wuhan was what hurt New York City,” said Hotez, “which is that virus transmission went on for six weeks before there was any public health intervention.”

In a videotaped interview with John Sharp, chancellor of The Texas A&M University System, Parker suggested an investigation modeled on the nonpartisan 9/11 Commission.

[…]

Hotez, who also participated in the interview with Sharp, said later that he feared a congressional panel would become “a political circus.” Instead he proposed a review by the National Academies of Sciences, Engineering and Medicine.

Among the questions Hotez wants answered: How, for the whole month of February, did the U.S. miss evidence that the virus was already here? Given the crowding and high number of underlying conditions in low-income neighborhoods, what was done to prepare African-American and Hispanic communities in the early days? Why didn’t the CDC have a centralized epidemiological model, including models of cities and metropolitan areas? And how can the U.S. prepare for future epidemics?

For those who are fans of comparing government to business, this is a very standard business thing to do. Call it an after-action review, or a root cause analysis, or just a plain old audit, it really is vital to learn from experiences, good and bad, so that you can understand what happened and why it happened, and what you can do better next time. I think we can all agree that there is plenty to be learned from this saga, and we all owe it to ourselves to do that. I would hope that much is non-controversial.

But let’s be real, there’s no way to do this that won’t involve politics. You can put together the bluest of blue ribbon panels, staff it with the bona fidiest of experts, and stick entirely to a just-the-facts narrative, it’s still going to be political. That’s because the single biggest actor in this drama was Donald Trump, and his influence on the decisions made at the state and local level was entirely political. Any review that doesn’t do a thorough accounting of this isn’t worth the effort. If Republicans haven’t figured out that Trump’s mishandling of this is what’s killing them in the polls right now, I can’t help them, but I would think they’d want to help themselves. If we manage to get an all-Democratic government next year (please, please), I won’t really expect Republicans to like anything such a report would say. That’s shouldn’t be the point, or anyone’s concern. Do a thorough review, get all the facts out into the open, learn everything there is to be learned, and let the chips fall where they may.

The reopening metric we should be heeding

Abstract

We report a time course of SARS-CoV-2 RNA concentrations in primary sewage sludge during the Spring COVID-19 outbreak in a northeastern U.S. metropolitan area. SARS-CoV-2 RNA was detected in all environmental samples and, when adjusted for the time lag, the virus RNA concentrations were highly correlated with the COVID-19 epidemiological curve (R2=0.99) and local hospital admissions (R2=0.99). SARS-CoV-2 RNA concentrations were a seven-day leading indicator ahead of compiled COVID-19 testing data and led local hospital admissions data by three days. Decisions to implement or relax public health measures and restrictions require timely information on outbreak dynamics in a community.

Introduction

The most common metric followed to track the progression of the COVID-19 epidemic within communities is derived from testing symptomatic cases and evaluating the number of positive tests over time.1 However, tracking positive tests is a lagging indicator for the epidemic progression.2, 3 Testing is largely prompted by symptoms, which may take up to five days to present4, and individuals can shed virus prior to exhibiting symptoms. There is a pressing need for additional methods for early sentinel surveillance and real-time estimations of community disease burden so that public health authorities may modulate and plan epidemic responses accordingly.

SARS-CoV-2 RNA is present in the stool of COVID-19 patients5-7 and has recently been documented in raw wastewater.8-10 Thus, monitoring raw wastewater (sewage) within a community’s collection system can potentially provide information on the prevalence and dynamics of infection for entire populations.11 When municipal raw wastewater discharges into treatment facilities, solids are settled and collected into a matrix called (primary) sewage sludge, which has been shown to contain a broad diversity of human viruses including commonly circulating coronavirus strains.12 Primary sludge provides a well-mixed and concentrated sample that may be advantageous for monitoring SARS-CoV-2. As viral shedding can occur before cases are detected, we hypothesize that the time course of SARS-CoV-2 RNA concentrations in primary sewage sludge is a leading indicator of outbreak dynamics within a community served by the treatment plant.

So in plain English, if you know what the level of SARS-CoV-2 is in your municipal wastewater, you will have a very accurate predictor of the new COVID-19 case rate in your community. And guess what? The city of Houston is tracking this very data. I don’t know if it’s being published anywhere, but it sure could shed some light on how things are really going around here. Other cities should be doing this as well – if they aren’t doing it already, they need to start – and that information should be collected and published at the state level as well. What are we waiting for?

How about some antibody tests?

That would be good.

After months of emphasis on diagnostic screening, contact tracing and research into possible treatments, Houston is about to deploy a new tool in the effort to contain COVID-19: antibody testing.

Baylor College of Medicine researchers last week presented evidence to school leadership that the blood test it developed to detect whether an individual has been infected with the coronavirus is highly accurate and ready for use in studies assessing the virus’ reach in the area. Such studies would provide the answer that hasn’t been ascertainable because of the shortage of diagnostic testing.

“This will tell us the severity of the disease based on prevalence, the number of people who have had the virus but do not show up in case counts because they were asymptomatic and weren’t tested,” said Dr. Paul Klotman, president of Baylor. “That’s needed to better understand how infections impact different Houston communities, the variations in those communities and the numbers in certain high-risk environments, like prisons and nursing homes.”

Klotman said he anticipates Baylor will partner with local health departments to determine optimal resource allocation — such as where to focus testing and contact tracing — based on the prevalence the studies find in communities.

A Baylor prevalence study based on antibody testing would put the Houston region among a handful of U.S. communities to conduct such research, which has found that more than 20 percent of people in New York City but only 4 percent of those in Los Angeles County have been infected. Klotman said he thinks Houston’s rate will be closer to the California number.

Such antibody testing, repeated over time, also would show the area’s progress toward herd immunity, the protection from a contagious disease that occurs when a high percentage of the population has either had the infection or been vaccinated. Experts say that percentage — there is no vaccine for the coronavirus yet — needs to reach at least 60 to 70.

There’s more, and you should read the rest. As a reminder, viral tests are to see who has the virus now, and antibody tests are to see who has had it in the past. Do not mix the two if you want to know the current case count. I would note that the Texas Tribune case tracker showed 10,921 infections in Harris County as of May 25. If that four percent guess is accurate, then given a county population of 4.7 million, the actual number of cases would be more like 188,000. That’s consistent, even a bit under, the typical antibody test experience, which winds up estimating the real infection count at about ten times the “official” count. And note that we’d have to have more than ten times that number to get close to the minimum threshold for herd immunity.

Anyway. I look forward to seeing what this can tell us. In conjunction with the wastewater testing, maybe we can finally get a clear local picture of this pandemic.

Making a better severe storm warning

Of interest.

We’ve all heard them – the blaring alerts that activate our cellphones or television when a severe weather warning is issued.

Perhaps our favorite weather app sent us a push notification, or we saw a television meteorologist pointing at vibrant boxes on a weather map. Whatever the medium, weather warnings have a way of finding us, especially whenever a severe thunderstorm is close by. Now, those warnings, specifically the way in which they’re generated, are in the process of getting a makeover.

Severe weather warnings are issued for individual thunderstorms; before 2007, entire counties would be alerted at once. Over the years, weather warnings have become more targeted – but one warning can still cover an expansive area. Moreover, conditions can vary wildly even within the region enclosed by a single warning.

Now, the National Weather Service is hoping to change that.

Kodi Berry leads the program that’s updating warnings at the National Severe Storms Laboratory (NSSL) in Norman, Oklahoma. The Forecasting a Continuum of Environmental Threats program, or FACETs, is an endeavor the National Weather Service is pursuing to communicate the hazards posed by severe thunderstorms on a hyperlocal level.

Berry says the goal is provide a more continuous flow of information for those who need it the most.

According to the National Severe Storm’s Laboratory, FACETs aims to improve weather watches and warnings to provide “detailed hazard information through the use of ‘threat grids’ that are monitored and adjusted as new information becomes available.”

Typical weather warnings are issued in the form of polygons digitally drawn on a map. If you’re within the polygon, you’re alerted and urged to take action – such as seeking shelter. But just a stone’s throw away, a neighboring home outside the polygon may not be given any special instructions. The current state of weather warnings is binary, akin to a “yes” or “no” to severe weather.

Berry’s team is hoping to improve that by creating a product that reflects the gray area in between. They are experimenting with displaying probabilities to reflect the range of possible outcomes in a rapidly-evolving severe weather event.

“There has been a lot of social science research that shows that, given probabilistic information, people make better decisions,” Berry said. “If we appropriately define these probabilities and what they mean, people can use them to make better decisions.”

See here for more on the NSSL, and here for more on FACETs. I like the idea overall and agree that more precise information that goes beyond the “threat/no threeat” binary makes sense, but I’m not so sure people make better decisions when given probabilistic information. There’s also a lot of research showing that people are not at all good at understanding risk levels, and at least in a political context it’s common to see people round down small-but-not-that-small probability events to “zero”, or the converse to “one”. I’m a fan of more and better data and so I approve of the idea, I just think it’s likely that how this data is presented and explained to the public will need to be refined a couple of times.

TxDOT hit with ransomware

Not great.

Texas’ transportation agency has become the second part of the state government to be hit by a ransomware attack in recent days.

On Thursday, someone hacked into the Texas Department of Transportation’s network in a “ransomware event,” according to a statement the department posted on social media Friday.

The departments’ website says some features are unavailable due to technical difficulties, but it is not clear what functions were affected by the attack. Agency officials did not respond to emailed questions Sunday.

[…]

Upon detecting the hack, staff at the transportation department “immediately” isolated the affected parts of the network and “shut down further unauthorized access,” according to the statement. James Bass, the department’s executive director, said his staff is “working to ensure critical operations continue during this interruption.″ The hacks follow a ransomware attack of unprecedented size that hit more than 20 local governments in Texas last summer.

See here for more on the attack on the court system’s website. In 2019, there was a coordinated attack on the systems of multiple small cities and counties.

I can’t find much in the way of news on this, so here’s TxDOT’s statement, via Twitter:

Maybe these two attacks are unconnected – there’s not enough information, such as what type of ransomware was involved and what the vector for it was, for me to take a guess – but the fact that there were two such attacks in a short period of time on two state systems sure seems suspicious to me. If I were at the state Department of Information Resources, I would be very busy, and more than a little concerned, right now. KXAN, CBS DFW, and Bleeping Computer have more.

Ransomware attack on state court system

Not great.

Websites for the Texas court system were still down Monday after a ransomware attack late last week left the network temporarily disabled, according to the Office of Court Administration.

Officials discovered the breach early Friday and quickly shut down sites and disabled servers to contain it, the office said in a statement. The hack did not impact e-filing and other services, many of which have been transferred to the cloud in recent years, according to the office.

“At this time, there is no indication that any sensitive information, including personal information, was compromised,” the office said. It added that websites for local trial courts are still available online.

The office said it detected the breach early and has refused to pay any ransom. While the courts have moved increasingly to remote hearings amid the coronavirus pandemic, the attack was unrelated, according to the office.

Officials have not said when the system will be back online, but they have set up a temporary website and are working with law enforcement and the Texas Department of Information Resources to investigate the attack.

As the story notes, this is not the first time that Texas governmental entities have been targeted by ransomware. The first thing that TDIR will need to figure out is whether this was actually targeted, or just a crime of opportunity, perhaps the result of someone opening a phishing email. If you follow this sort of news, you know that ransomware attacks are on the increase around the world; here’s a prominent recent example. I’m sure the system will recover from this, and good for the OCA if they detected it quickly. We just need to up our vigilance and defensive measures to stay on top of this.

Are we sure we’re using the right models?

Let’s check our assumptions before we do anything dumb.

Be like Hank, except inside

A widely followed model for projecting Covid-19 deaths in the U.S. is producing results that have been bouncing up and down like an unpredictable fever, and now epidemiologists are criticizing it as flawed and misleading for both the public and policy makers. In particular, they warn against relying on it as the basis for government decision-making, including on “re-opening America.”

“It’s not a model that most of us in the infectious disease epidemiology field think is well suited” to projecting Covid-19 deaths, epidemiologist Marc Lipsitch of the Harvard T.H. Chan School of Public Health told reporters this week, referring to projections by the Institute for Health Metrics and Evaluation at the University of Washington.

Others experts, including some colleagues of the model-makers, are even harsher. “That the IHME model keeps changing is evidence of its lack of reliability as a predictive tool,” said epidemiologist Ruth Etzioni of the Fred Hutchinson Cancer Center, who has served on a search committee for IHME. “That it is being used for policy decisions and its results interpreted wrongly is a travesty unfolding before our eyes.”

The IHME projections were used by the Trump administration in developing national guidelines to mitigate the outbreak. Now, they are reportedly influencing White House thinking on how and when to “re-open” the country, as President Trump announced a blueprint for on Thursday.

The chief reason the IHME projections worry some experts, Etzioni said, is that “the fact that they overshot” — initially projecting up to 240,000 U.S. deaths, compared with fewer than 70,000 now — “will be used to suggest that the government response prevented an even greater catastrophe, when in fact the predictions were shaky in the first place.”

That could produce misplaced confidence in the effectiveness of the social distancing policies, which in turn could produce complacency about what might be needed to keep the epidemic from blowing up again.

[…]

“This appearance of certainty is seductive when the world is desperate to know what lies ahead,” Britta Jewell of Imperial College and her colleagues wrote in their Annals paper. But the IHME model “rests on the likely incorrect assumption that effects of social distancing policies are the same everywhere.” Because U.S. policies are looser than those elsewhere, largely due to inconsistency between states, U.S. deaths could remain at higher levels longer than they did in China, in particular.

While other epidemiologists disagree on whether IHME’s deaths projections are too high or too low, there is consensus that their volatility has confused policy makers and the public.

See here and here for previous mentions of the IHME. As you may recall, I noted the very wide error bars on its numbers, which tends to be overlooked in the way the stories about this model were written. The IHME is the model that Greg Abbott has used for his reopening plan, so the fact that its projections can change significantly as new data comes in should be of concern. Plus, you know, the whole we are bad at testing thing. However you look at it, the data is noisy, and there’s evidence to suggest there are a lot more people out there with the virus than our level of testing has had the ability to detect. Which is to say again, there’s a lot we just don’t know yet. We shouldn’t rely on one view of the data for our understanding of what is happening, in the same way that we should not rely on any one single poll to understand what is happening in a given election.

Treating COVID-19 patients at nursing homes

This is a huge can of worms.

When Larry Edrozo got a phone call from his mother’s nursing home in Texas City telling him she was being treated for the novel coronavirus with an unproven pharmaceutical drug, he had two questions: why was she getting the drug if she had not been showing symptoms, and who gave consent?

Helen Edrozo, 87, is one of 56 residents at the Resort at Texas City who tested positive for the coronavirus, and one of 39 residents being medicated with hydroxychloroquine, a drug typically used to treat malaria and lupus that has shown some evidence of possibly tamping down symptoms of the virus.

The use of hydroxychloroquine to treat coronavirus patients has drawn controversy globally as the medical community and public debate the ethics of testing a medication before significant research is available — and in the case of elderly patients such as those at The Resort at Texas City, on a population that is statistically more vulnerable to the virus. While President Donald Trump has touted the drug’s benefits, a large controlled study of hydroxychloroquine has not yet been completed, and some doctors warn the drug combination used for the experimental treatment could have severe, potentially deadly side effects.

Larry Edrozo was initially told by an administrator at the nursing home that Helen would not eligible for hydroxychloroquine treatment because she was not showing symptoms. But on Monday, a nurse at the facility phoned him to tell him that his mother’s carbon monoxide levels in her blood had elevated slightly and that she had already begun a hydroxychloroquine dose.

Edrozo was stunned. His mother has dementia, meaning that, as her power of attorney, he is supposed to sign off on any medical treatment she receives at the nursing home.

“I (told the nurse), ‘OK, well, since you’ve already started (treatment), I guess I would write in my notes that the question was raised about consent and what happened to that?’” Edrozo said. “I have not received a call back.”

Dr. Robin Armstrong, the medical director at The Resort, who prescribed the medication shortly after Amneal Pharmaceuticals donated 1 million tablets to the Texas Department of State Health Services pharmacy, said the decision was between him and his patients. He said he did not notify families before the drugs were administered because it was not necessary and time consuming.

“If I had to call all the families for every medicine that I started on a patient, I wouldn’t be treating any patients at all; I would just be talking to families all the time,” Armstrong said

But ethicists say informed consent is one of the most important factors in any treatment, and several people with family members at the Resort at Texas City being treated with hydroxychloroquine say that they were not asked to give consent, despite having power of attorney over their sick relatives.

Still, faced with the desperation of potentially losing his mother to the coronavirus, Edrozo felt he had no other choice than accept this course of treatment.

“When the people are blasting the doctors and the governor’s office about human guinea pigs, I’m sort of there with them,” Edrozo said. “But then I want to ask them, ‘What if it was your mother, or your spouse or your child?’”

As the kids say, there’s a lot to unpack here. At the most basic level, there’s nothing but anecdotal evidence that hydroxychloroquine has any effect on coronavirus. There are no studies worthy of the name showing that it would help. Maybe it will, maybe it won’t, we just don’t know. And that’s without taking into account the inability of these patients on whom the tratment is being tested to give informed consent for their participation. Or the fact that hydroxychloroquine is an actual drug used by people suffering from lupus and malaria, and Donald Trump’s obsession with it as an unproven treatment for COVID-19 means potential shortages for those patients. Did I mention that the doctor leading this effort is a Republican activist who got a supply of the drugs through political connections, and who therefore has a vested interest in making Trump and his hydroxychloroquine predictions look good? All this, and even if it does help some of these patients it won’t tell us anything about the effectiveness of hydroxychloroquine as a treatment because this isn’t a controlled study. Keep in mind, everyone who has recovered from COVID-19 has done so on their own. We’ll have no way of knowing whether the people at The Resort who recover would have done so anyway – that’s why doing controlled studies matter, so you can make valid comparisons. I very much get Larry Edrozo’s dilemma, but he and everyone else involved in this deserved to have full knowledge of the risks and benefits so they could make their own decision.

The digital divide

Online learning is great, if you can get online.

The lack of access to technology among students — commonly referred to as the “digital divide” — has come into sharper focus in recent weeks as school districts across Houston transition to online-based learning amid widespread school shutdowns.

Districts throughout the region are scrambling to equip tens of thousands of children with computers and internet access, jockeying with each other to secure coveted devices in high demand during the pandemic. In the meantime, many districts are providing those students with rudimentary paper materials, asking families to return completed coursework to their schools or take pictures of completed worksheets and send them to teachers.

“This has been on the education docket for, gosh, probably at least 20 years,” said Alice Owen, executive director of the Texas K-12 CTO Council, an association that supports school district chief technology officers. “It’s been a struggle for people to realize that this is an important piece of learning for students if we want to keep them competitive on a global scale.”

Educators and advocates long have warned about the digital divide facing American children, with the nation’s most impoverished children suffering most. The ubiquity and declining cost of computers and internet access has helped shrink the gap, but stark disparities remain.

In the Houston area’s 10 largest school districts, about 9 percent of households — nearly 142,650 — do not have a computer, according to the most recent U.S. Census estimates. Nearly twice that number — about 267,250 households — lack broadband internet access.

Three of the region’s largest and most impoverished districts — Alief, Aldine and Houston ISDs — face the greatest shortages, according to Census data and estimates from district leaders.

[…]

Despite extensive warnings about the digital divide, state and federal legislators have not allocated nearly enough funding to schools to cover costs associated with providing laptops, wireless internet devices and broadband services to all students at home.

Districts can obtain some technology and internet access at steep discounts through a federal program known as E-Rate, but the benefit does not extend to take-home computers or wireless hotspots for students.

“If we want our kids to be competitive and stay up-to-date with tech, we need to be investing in our students for the future,” Owen said. “We’ve got to get over the way school used to be run, and we need to think about the ways that schools are run in the future.”

In a letter sent last week to the top four ranking members of Congress, 35 Democratic senators called for providing $2 billion in E-Rate funds that would allow schools and libraries to deliver wireless internet devices to students without connectivity at home.

“Children without connectivity are at risk of not only being unable to complete their homework during this pandemic, but being unable to continue their overall education,” the senators wrote. “Congress must address this issue by providing financial support specifically dedicated to expanding home Internet access in the next emergency relief package so that no child falls behind in their education.”

Maybe addressing this could be part of Infrastructure Week, or maybe it can be its own item. As the story notes, HISD and some other districts issue laptops to high school students – my daughter has one – which helps with those students, but obviously only goes so far. Charters are not exempt – KIPP reports a similar issue with its students. This is, plain and simple, an issue of poverty. If fixing the underlying issue is too hard, then maybe we can agree that all students need to have the equipment required for an education, and provide them all with laptops and Internet access. The choice is ours – are we going to learn from this crisis, or are we going to face the same problems the next time, without the excuse that we didn’t know any better?

We are doing a good job of keeping our distance

That’s what our phone say, anyway.

Harris County residents are doing a good job keeping their distance, according to location data culled from smartphones, earning an “A” on a nationwide scoreboard.

The Social Distancing Scoreboard is a creation of Unacast, a Norway-based company that provides location data for business clients. The tool tracks the decrease of movement by people in a location over time to determine whether they are staying at home and assigns a letter grade, drilling down to the county level. The grade is tracked against the number of COVID-19 cases in each location.

It does not track whether people are staying six feet apart from each other — yet.

[…]

Overall, the United States scores a “B,” with the District of Columbia doing the best job of social distancing, followed by Alaska. Texas gets an A overall, as does Harris County.

Schleicher County, south of San Angelo, gets the highest score in Texas; Oldham County, west of Amarillo, has the worst.

You can fool around with the Social Distancing Scoreboard here. It gets its data from various smartphone apps – thank you for turning on location services, by the way – though it doesn’t specify which apps, per the Washington Post. The data for Texas was last updated on March 21, prior to all of the stay-at-home directives, so one would expect the mobility levels to drop further. It’s a good start, at least.

Preserving Texas’ film history

Cool story.

Click play on the grainy, black-and-white image titled simply “Houston Time Service” on the website of the Texas Archive of the Moving Image and you’re treated to a 110-second Houston love story.

The film, from the 1940s, is about a phone number Houstonians could call to get the correct time. Ruth McClain Graham owned the service, according to an Oct. 24, 1947, Houston Chronicle story. Two years earlier she had married Shadrack E. “Shad” Graham, an itinerant filmmaker, who, apparently taken with the proprietor, produced the film promoting the business.

But film, like love, can be short-lived, and that’s what has driven Caroline Frick’s race against time. The role of film preservationists like Frick, an associate professor of film at the University of Texas’ Moody College of Communication in Austin, becomes ever more crucial as moving images depicting life and history become unplayable.

As the years play on, the decay of aging motion picture film accelerates, as does the quality of magnetic tape on which video is recorded. Video projectors and old-format tape machines break, are not repaired and discarded. The race to get these recordings into a digital format – also unlikely to survive forever – becomes more crucial with each passing year.

“This is what we are trying to prevent,” says Frick, who founded and is executive director of the Texas Archive of the Moving Image, or TAMI, in 2003, opening a plastic bag filled with what looks at first glance to be beef jerky. It’s actually decomposing celluloid, curled and blackened. The smell from the bag is a pungent, vinegary rot, and in TAMI’s crowded offices near downtown Austin, you can catch a whiff if you stand next to stacks of boxes filled with 8-, 16- and 35-millimeter film.

Another threat is in the shrinking universe of ways to watch these historic movies, a dwindling number of obsolete devices available for playback. Frick points to a Sony reel-to-reel videotape machine on the floor that once was the pride of a television station editing room. It was designed to work with a now-abandoned, 1-inch tape format.

“We were able to play something once on that after we got it, and then it broke,” she says, sighing. “We’re still looking for parts.”

A staff of five — all part-timers — are in the office on this chilly January day. Some work on physical restoration of film, others scan it into computers for digitization. Another crew catalogs and curates, putting context to the images that, ultimately, stream across the internet to computers, phones and tablets.

It is a daunting task, hampered by a lack of funding — TAMI’s annual budget is in the $300,000 range — and made overwhelming by the sheer amount of content that flows in. So far, TAMI has digitized about 58 terabytes of film and video, but only 10 percent of that is available for viewing at its website, texasarchive.org.

“The number one reason for the disconnect between what we have digitized vs. what is streaming is budget – the human labor of researching and contextualizing the content,” Frick says. “Everyone is excited about what AI will be able to do some day (for automated curation) but, as of yet, nothing is as reliable or useful as the human eye and brain.”

I’m old enough to remember calling a phone number to get the correct time. Crazy to think about now, but here we are. In any event, preserving old film is a much more challenging task than preserving old books because of the technological barriers. Look at it this way: Most of us have obsolete technology from recent years that has information on it that is now unreadable to us, like various forms of portable storage from computers. The TAMI folks have to deal with machines from decades ago, where there may literally be nothing else like them in existence. Once these old films are gone, that’s it, they’re completely lost to history. Whatever the value of any individual piece of celluloid may be, it sure is a shame to lose something like that. Read the rest of the story and check out the Texas Archive of the Moving Image. Maybe you have something that would interest them.

Calendar reform

Well, this is an interesting idea.

Feb. 29ths, like the one tacked to the end of [last] month, exist because Earth’s orbit and human calendars are slightly out of sync. The planet completes its 584-million-mile loop around the sun in 365 days — plus 5 hours, 48 minutes and 46 seconds. Leap days are designed to compensate for the excess time.

But, if two Johns Hopkins University professors had their way, this leap year would be the last of its kind.

They would replace the calendar with a new version. Theirs, the Hanke-Henry Permanent Calendar, is 364 days long. It is consistent: The year always begins on a Monday. Your birthday always falls on the same day of the week.

“The calendar will be exactly the same, every year,” said Richard Conn Henry, an astronomer at Johns Hopkins University and one of the calendar’s designers.

February would always have 30 days, as would January, April, May, July, August, October and November. The other four months would have 31 days. There would be no February leap days. Instead, “every five or six years,” Henry said, “we’ll have an extra week at the end when you can party.”

[…]

“The Gregorian calendar was set up by astronomers, people who knew what they were doing, and it is very accurate,” Henry said. “That’s the problem. We don’t need a terribly accurate calendar. What we need is a calendar that is suitable for human beings to order their lives by.”

Henry enlisted his colleague at Johns Hopkins, economist Steve H. Hanke, to help. “Dick brought this up and basically gave me an assignment: ‘Hanke, find out the economic implications of this thing,’ ” Hanke said.

Hanke estimates the upfront costs would be less than the Year 2000 adjustment, which, in the United States, was about $100 billion.

“The benefits, from just not having to reproduce calendars every year, physical calendars, would pay for the thing right away,” he said.

Having the date fall on the same day of the week every year eliminates inefficiencies with planning and scheduling that the “herky-jerky” Gregorian calendar has, Henry said.

Every so often, in the Gregorian calendar, companies add a week to their fiscal quarters. Apple did so in the first quarter of 2012, and reported “very good, strong earnings,” Hanke said. “Of course, they had an extra week of revenues coming in.”

A year later, Apple’s first quarter of 2013 appeared comparatively weak — because it lacked the benefit of an extra week, Hanke said — and the company’s stock dropped.

“Our calendar fixes that problem,” Hanke said, because business would consistently operate on 91-day quarters.

Holidays and your birthday would fall on the same day of the week every year, which if nothing else simplifies things. The story doesn’t delve into the mechanics of that “bonus week”, which would seemingly be every six years. Would it actually be a national week off, or just another work week? What would we call it? And if you think being a Leap Day baby is weird, imagine being a kid born during Bonus Week.

Hanke and Henry think their calendar could be implemented via presidential executive order. I have a hard time imagining that would actually happen. The rest of the world would adjust if the US did something as eccentric as this – they would have to, in the same way everyone adjusts to Daylight Savings Time, which occurs at different times around the globe – but I doubt they would follow suit, and having to deal with two different business calendars might just eat into the cost savings these guys envision. It’s an interesting idea, and if we were designing a new global system from scratch I’d like it, but as things stand I’m fine with the status quo.

The robot nurse

We are living in the future, for better and for worse.

https://www.instagram.com/p/B01H56Fn8_0/

A friendly one-armed, bright-eyed robot is roving the hallways of Medical City Dallas’ Heart and Spine hospitals, helping nurses with routine tasks that previously took time away from patient care.

Nicknamed Moxi and regarded as one of the staff, the robot is equipped with sensors to help it navigate, and even anticipate people’s movements, as it travels across hospital floors. Medical City Dallas partnered last fall with Austin-based artificial intelligence firm Diligent Robotics Inc. to become the first North Texas hospital to employ a robot full time in a clinical setting.

“When we were opening up the hospital back in October, one of the things we wanted to really focus on was being an innovation center and bringing new technology to the health care setting,” Medical City Chief Operating Officer Josh Kemph told The Dallas Morning News.

When a nurse is interacting with it in a way that would normally trigger an error message, Moxi instead emits pleasant beeps and chirps to notify them. Some patients even have their own names for the assistant, which has its own Instagram account run by Diligent.

But Moxi is so much more than just a pretty face.

Texas will face a shortage of more than 71,000 nurses by 2030, according to the Texas Health and Human Services Commission. And with the demand for nurses expected to only continue increasing, Medical City Dallas director of surgical and procedural services Stefanie Beavers says she hopes it will also make it easier for the hospital’s existing workforce to optimize their day-to-day work.

“This really offers health care facilities an opportunity for the nursing workforce to focus on patient care and be directly at the bedside versus taking them away, and allowing their time to be truly dedicated to patient care tasks,” Beavers said.

It never crosses the threshold into patient care, instead delivering things like blood samples back and forth to a lab and updating patients’ medical records instantaneously for hospital staff.

“She’s really meant to be a team member that’s supporting you in the background,” Beavers said.

For now, at least, Moxie is a modern version of the FBI mail robot, which does simple drudge work like delivering specimens and allowing the human nurses to do more important things. It’s also a lot cheaper to employ than human nurses, or human nurses’ aides, and in the way of driverless cars, it’s just a matter of time before they have the capability to cross that threshold into patient care. That may be 20 or 30 years down the line, but it’s out there somewhere. I just hope we can have a productive conversation about what that will mean for the rest of us before it happens.

How Nuro is mapping Houston

Really interesting story.

On the muggy streets of suburban Houston, amid McMansions, bright green lawns and stately oak trees, a futuristic race is quietly afoot.

The contestants are not people but late-model Toyota Priuses outfitted with an array of sophisticated sensors. Despite fierce competition and unending pressure to perform, the nearly silent electric vehicles do not speed. They move cautiously, rigorously following traffic laws and never topping 25 mph.

Their goal is not an easily discerned finish line but to map large swaths of the nation’s fourth-largest metropolis, a sprawling patchwork of neighborhoods, mini-cities, strip malls, gridlocked superhighways and mazelike gated communities – an area so prodigious in size it easily could swallow Manhattan, Brooklyn, Queens and Staten Island whole.

The vehicles are owned by Nuro, a Silicon Valley robotics company with an ambitious goal – to become the world’s preeminent autonomous delivery service, allowing millions of people to have groceries and other goods delivered by robots instead of making trips to the store, potentially reducing traffic and kicking off a new chapter in our relationship with machines. For months now, Nuro’s robotically piloted vehicles have been successfully, if quietly, delivering groceries to restaurants and homes around Houston, the vehicles’ sensors mapping the city as they go.

The faster Nuro’s vehicles map Houston’s notoriously chaotic roadways, the faster the company can refine its software and export its business model elsewhere. But time is in short supply.

Like Nuro, companies such as Amazon, Alphabet-owned Waymo, Robomart, General Motors’ Cruise division, Ford-affiliated Argo AI, Starship Technologies and many others are also rushing to deploy high-functioning autonomous vehicles for delivery and passenger transport, with some companies attracting major deals and billions in funding. Their goal is to earn public trust and offer real-life convenience, experts say, heightening their chances of securing a valuable foothold in a new era defined by autonomous transportation.

To get there, they will first have to run their autonomous vehicles, or AVs, through millions of miles of driving tests in cities such as Houston until they are glitch-free and unquestionably safe.

“The pressure is real,” said David Syverud, head of robot operations at Nuro. “And to be clear, it is a race in the AV space to deploy quickly and be the first to really get there.”

It goes from there, and it’s worth your time to read, even if it’s a few weeks old at this point. We’ve met Nuro before, and I see their cars around; I’ve seen a couple in and around my neighborhood. Like most stories written about Houston by people not in Texas, this one is both a window into how others view us, and how they can get confused about certain basic things we understand. Like, for example, how you have to distinguish between the city of Houston and the greater Houston area. This is what I mean:

Company officials say they were also drawn to Houston for the complexity of its metropolitan environment, a puzzle of independent communities, each with its own road conditions, zoning ordinances, parking rules and traffic laws. Some area neighborhoods offer wide lanes and little traffic, others are narrow and perpetually hectic – providing the company’s robotic software a massive variety of testing conditions.

As the country’s most ethnically diverse large city – and with a foreign-born population of 1.4 million – Houston also is a place where Nuro officials could probe fundamental questions about its business model.

“The big question for us is: Who is going to use this service, and how often will they do it?” said Sola Lawal, a Nuro product operations manager based in Houston who formerly worked for Uber. “Our robots don’t care who they’re delivering to, but we want to understand how different demographics interact with and feel about the robots. Houston allows for this broad swath of experience in one city.”

That’s all well and good, and it’s easy to see why Houston would be an attractive testing ground, but come on. The city of Houston has a population of about 2.3 million. I assure you, the population of the city of Houston is not three-fifths foreign-born. The greater Houston metropolitan area has a population of about seven million, and I daresay that’s what they meant when they dropped that statistic in the story. But please, let us be precise about these things.

Anyway, despite such glitches, the story is worth reading, so go check it out. We occasionally use grocery delivery, via Whole Foods and Amazon Prime. They leave the goods in a cooler we put out on the porch, and however successful this Nuro project is I don’t see that part of the task being robot-ified any time soon. There’s a lot of money being bet on this business expanding rapidly. I’m usually skeptical about this sort of thing, but what do I know?

“Coordinated cyberattack” on several Texas cities

That doesn’t sound good.

Twenty-three Texas towns have been struck by a “coordinated” ransomware attack, according to the state’s Department of Information Resources.

Ransomware is a type of malicious software, often delivered via email, that locks up an organization’s systems until a ransom is paid or files are recovered by other means. In many cases, ransomware significantly damages computer hardware and linked machinery and leads to days or weeks with systems offline, which is why it can be so costly to cities.

According to a weekend update by the Texas DIR, the attacks started Friday morning and though the locations aren’t named, “the majority of these entities were smaller local governments.”

Texas Governor Greg Abbott ordered a “Level 2 Escalated Response” on Friday following the incident, according to a statement from Governor’s Office deputy press secretary Nan Tolson. This response level, determined by the state’s Department of Emergency Management, is part of a four-step response protocol, and is one step below the highest level of alert, level 1 or “emergency.”

According to state emergency management planning guide, this means “the scope of the emergency has expanded beyond that which can be handled by local responders. Normal state and local government operations may be impaired.”

In addition to the state and local agencies assisting with the response, “Governor Abbott is also deploying cybersecurity experts to affected areas in order to assess damage and help bring local government entities back online,” Tolson said.

This NPR story has more details.

The Federal Bureau of Investigation and state cybersecurity experts are examining the ongoing breach, which began Friday morning and has affected mostly smaller local governments. Officials have not disclosed which specific places are affected.

Investigators have also not yet identified who or what is behind the attack that took the systems offline, but the Texas Department of Information Resources says the evidence so far points to “one single threat actor.”

Elliott Sprehe, a spokesman for the department, said he was “not aware” of any of the cities having paid the undisclosed ransom sought by hackers. He said the areas impacted are predominantly rural. The department initially put the number of cities attacked at 23.

Two cities so far have come forward to say their computer systems were affected. Officials in Borger in the Texas Panhandle, said the attack has affected city business and financial operations. Birth and death certificates are not available online, and the city can’t accept utility payments from any of its 13,25o residents. “Responders have not yet established a time-frame for when full, normal operations will be restored,” city officials said.

[…]

Experts say that while government agencies have increasingly been hit by cyberattacks, simultaneously targeting nearly two dozen cities represents a new kind of cyberassault.

“What’s unique about this attack and something we hadn’t seen before is how coordinated attack this attack is,” said threat intelligence analyst Allan Liska. “It does present a new front in the ransomware attack,” he said. “It absolutely is the largest coordinated attack we’ve seen.”

Liska’s research firm, Recorded Future, has found that ransomware attacks aimed at state and local government have been on the rise, finding at least 169 examples of hackers breaking into government computer systems since 2013. There have been more than 60 already this year, he said.

The city of Keene, near Fort Worth, was also hit, and their Mayor said the attack came via their IT provider, as these small towns outsource that task since they don’t have sufficient resources to do it themselves. This is a real problem that’s going to keep happening, and we really should put more money and effort into fighting against it at a state and national level. Good luck to all involved in cleaning up the mess. A more recent statement from the Texas DIR is here, and the Star-Telegram, the Chron, and the Trib have more.

Big Bend yields a new dinosaur species

Cool.

A new, more primitive species of dinosaur was discovered at Big Bend National Park this week.

The fossil of the new specials, Aquilarhinus palimentus, was unearthed in the 1980s by Texas Tech University Professor Tom Lehman. But because the bones were so “badly weathered and stuck together,” it was not until recently that researchers could analyze it, according to a release from the park.

Earlier research concluded the fossil was related to the Gryposaurus genus, or duck-billed dinosaurs. New research shows the fossil is linked to a more primitive species that is helping researchers draw conclusions about how this species of dinosaurs evolved over time, according to the release.

“Its existence adds another piece of evidence to the growing hypothesis, still up in the air, that the group began in the southwestern area of the U.S.,” lead author Dr. Albert Prieto-Márquez from the Institut Català de Paleontologia Miquel Crusafont, near Barcelona, said in the release.

The full report is here, with a more readable summary here and here. As we know, Texas is a rich source of fossils, from various paleontological eras. May it ever serve as a fruitful source of discovery.

Perspective on the anti-vaxx situation

Maybe it’s not as bad as we think.

It’s certainly true that pockets of vaccine refusal persist in this country, as they have for many years. If those pockets are now experiencing greater numbers of measles cases, it may be on account of dire trends in far-off places.

This global explanation only kicks the can a little farther down the road, however. Measles cases are spreading here because they’re spreading overseas—OK, fine. But why is measles spreading overseas?

[…]

Are vaccination rates really on a downward trajectory? Once again, the actual data complicate this narrative. Global immunizations against measles, like those in the U.S., are at or near an all-time high. Since the start of this century, the proportion of people around the world who have received at least one dose of the measles vaccine has increased by almost one-fifth. Meanwhile, the use of a second dose of the vaccine (which makes it more effective) has more than quadrupled on the global scale. In 2000, just 15 percent of people were getting both shots. Now, that number is up to 67 percent and still rising.

The salutary effects of all this work could not be more apparent. The global number of people who contract measles and the global number of people who die from it have each gone down by about 80 percent since 2000. As recently as 1980, more than 4 million cases of measles were reported every year. Despite massive population growth since then—an uptick of several billion people, worldwide—the annual number of measles cases has dropped to about one-fiftieth of what it used to be, to a few hundred thousand cases per year.

Given all this recent progress, the global measles crisis that’s underway seems somewhat paradoxical.

Basically, the argument is that outbreaks like we’ve seen with measles tend to burn quickly through the susceptible population, then run out of steam, and that the biggest cause of not being vaccinated in the US is not anti-vax foolishness but lack of access to medical care. The author argues that the full picture of the data is often not represented or mis-represented in media stories, which has caused some level of overreaction among vaccine proponents. There’s a lot of detail, so read it all and see what you think.

Do we still want to go to Mars?

Hot take: I dunno.

Before the U.S. put the first man on the moon, before the Soviet Union launched the first satellite, people thought aliens lived on Earth’s nearest planetary neighbor.

The belief sparked fear in some — and outright panic when Orson Welles broadcast reports in 1938 of a Martian invasion drawn from the novel “The War of the Worlds.”

But it inspired others to question: Are we alone in the universe?

“Perhaps the single, most consuming scientific question of the space program is: ‘Does extraterrestrial life exist in our solar system?’” rocket pioneer Wernher von Braun wrote in a 1969 proposal to send humans to Mars.

In the decades since, even after scientists concluded the aliens of science-fiction fame do not live on Mars, the Red Planet has captivated the world’s imagination unlike any other.

It’s been the subject of countless movies, books and TV shows. It’s been an inspiration for folklore. And it’s been a desired destination for dreamers — a barren, dusty terrain that could offer scientists a look at what may lie ahead for Earth.

But a human mission to the Red Planet was out of reach in the 1960s. And it remains elusive today.

Top NASA officials have tentatively aimed for a human mission to Mars in 2033, but even they admit that timeline is aggressive. NASA still needs to develop a spacecraft capable of transporting humans to Mars; a method of propulsion to cover the distance more quickly; and a surface-landing vehicle that can handle the Martian climate.

Can NASA get it done in 14 years?

“I don’t know,” replied Bill Gerstenmaier, NASA’s associate administrator for human exploration and operations.

“It’s a function of how much (progress) the program can make,” he told the Houston Chronicle in April. “The technology and the hardware is reasonable, but can we get the budget? That I don’t know.”

Some question going at all. The U.S. already has successfully landed eight robotic missions on the Red Planet.

“It’s kind of questionable about what there is to be gained,” Apollo 7 astronaut Walt Cunningham told the Chronicle. “You have to find some rationalization and justification in order to spend what it costs to go to Mars.

“I think that’s a long shot right now.”

On the one hand, I think there’s a lot to be learned by planning and executing a manned flight to Mars. I feel like as much as private firms are now in the space business, the public sector needs to continue to have a strong presence, if only to ensure that the knowledge gained by space travel remains in the public sphere. On a strictly parochial level, someone is eventually going to do this, and I’d rather it be the US than China or Russia.

Against that, it’s fair to question the value of the knowledge we’d get from a manned flight versus an unmanned flight. This would cost a ton of money at a time when there are higher priorities. It’s far from clear that this is something the public wants, and this is one of those times when having the President get behind it would not help at all. (I felt a little queasy just typing that out.) The idealist in me would love to see this happen. The pragmatist is far from convinced.

Bankrolling the anti-vaxxers

This is why we can’t have nice things.

A wealthy Manhattan couple has emerged as significant financiers of the anti-vaccine movement, contributing more than $3 million in recent years to groups that stoke fears about immunizations online and at live events – including two forums this year at the epicenter of measles outbreaks in New York’s ultra-Orthodox Jewish community.

Hedge fund manager and philanthropist Bernard Selz and his wife, Lisa, have long donated to organizations focused on the arts, culture, education and the environment. But seven years ago, their private foundation embraced a very different cause: groups that question the safety and effectiveness of vaccines.

How the Selzes came to support anti-vaccine ideas is unknown, but their financial impact has been enormous. Their money has gone to a handful of determined individuals who have played an outsize role in spreading doubt and misinformation about vaccines and the diseases they prevent. The groups’ false claims linking vaccines to autism and other ailments, while downplaying the risks of measles, have led growing numbers of parents to shun the shots. As a result, health officials have said, the potentially deadly disease has surged to at least 1,044 cases this year, the highest number in nearly three decades.

The Selz Foundation provides roughly three-fourths of the funding for the Informed Consent Action Network, a three-year-old charity that describes its mission as promoting drug and vaccine safety and parental choice in vaccine decisions.

Lisa Selz serves as the group’s president, but its public face and chief executive is Del Bigtree, a former daytime television show producer who draws big crowds to public events. Bigtree has no medical credentials but holds himself out as an expert on vaccine safety and promotes the idea that government officials have colluded with the pharmaceutical industry to cover up grievous harms from the drugs. In recent weeks, Bigtree has headlined forums in ultra-Orthodox Jewish communities in Brooklyn and Rockland County, New York, both areas confronting large measles outbreaks.

“They should be allowed to have the measles if they want the measles,” Bigtree told reporters outside the Brooklyn meeting on June 4. “It’s crazy that there’s this level of intensity around a trivial childhood illness.”

It’s like Margaret Mead said: Never doubt that a small group of thoughtless, super-wealthy citizens can change the world for the worse; indeed, it’s the main thing that does.

New fronts in the war on mosquitoes

Science marches on.

In the center of Anita Schiller’s dragonfly-ring-clad hand, a dragonfly nymph is scooting around.

The dedicated naturalist and entomologist is explaining how the insect (which is a water-dwelling dragonfly with gills before it grows wings) expels water from its posterior in a squirting fashion. She laughed and called it “fart propulsion.”

Schiller is leading a team of four from the Harris County Precinct 4’s Biological Control Initiative through a man-made flood control site at the corner of Spring Cypress Road and Telge Road. They are releasing dragonfly and damselfly nymphs into the water, along with carnivorous plants, to help reduce the infectious mosquito population.

“What we’re bringing in will help stack the deck against mosquitoes,” Schiller, director of the initiative, says. “Mosquito suppression is built into the design of the project.”

The Biological Control Initiative started in 2012 with a mission to “find native agents to benefit from the locally adapted phenotype” to counter the mosquito population.

So, what exactly does that mean?

The agency rears human-friendly biological agents, such as dragonflies, damselflies and carnivorous plants, in a lab to be released into the wild to control the blood-sucking and potentially diseased mosquitoes that afflict Southeast Texas year round.

Dragonflies are robust, while damselflies are more dainty-looking. But both are ferocious eaters as adults and gleaning eaters as nymphs.

Introducing native and naturally flood-resistant plants into wetlands and areas of unavoidable standing water gives a larger return-on-investment than just a pesticide approach, Schiller says. The plants also don’t require regular maintenance.

The initiative has also garnered attention for its introduction of “mosquito assassins” in the Houston area. These mosquitoes, which are typically larger than other native species, do not feed off humans and instead work to eliminate the dangerous mosquitoes, such as Asian tiger (Aedes albopictus), southern house (Culex quinquefasciatus) and yellow fever (Aedes aegypti) mosquito larvae.

As the story notes, Harris County is also using mosquito traps and mutant mosquitoes to control our skeeter population. It’s a big deal, because mosquitoes mean Zika, and standing water means mosquitoes. Do your part to combat the buzzing menace by emptying out whatever pots or containers you have in your yard that fill up with rainwater after a storm. The BCI will take it from there.

Our measles risk

Do I spend too much time worrying about stuff like this, or do I not spend enough time on it?

Harris County is one of the nation’s most vulnerable counties to a measles outbreak, according to a new study based on international travel and the prevalence of non-medical vaccine exemptions.

The study, published Thursday in the journal Lancet Infectious Diseases, ranks Harris County as the county 9th most at risk of having clusters of people contract measles, the highly contagious, potentially fatal virus that has re-emerged as a public health threat after having been largely eradicated at the turn of the century. Tarrant and Travis counties also are at high risk of an outbreak, according to the study.

“Texas’ showing is on par with the other 16 states that allow vaccine exemptions for conscientious or personal reasons,” said Sahotra Sarkar, a University of Texas Austin professor and the study’s lead author. “You can expect the state, like other parts of the nation, to see more cases.”

Sarkar said Harris County’s vulnerability is mostly the result of its considerable international travel. The county’s number of non-medical vaccine exemptions was not among the state’s highest in a Texas health department report released earlier this week.

[…]

The new study was conducted by Sarkar and a Johns Hopkins University researcher using risk assessment models similar to one they used to correctly predict that Zika, the mosquito-born virus that can cause serious birth defects, would first affect Texas and Florida after it began spreading from the Southern Hemisphere midway through this decade. It also correctly predicted areas already experiencing measles outbreaks, such as Washington, Oregon and New York.

The authors didn’t consider the locations of measles cases already recorded. Instead, they looked at non-medical vaccine exemptions, international air travel and the incidence of measles in countries from which people came to the United States, particularly India, China, Mexico, Japan, Ukraine, Philippines and Thailand. In all, some 112,000 people have been diagnosed with measles outside the U.S. this year, according to the World Health Organization.

Peter Hotez, a Baylor College of Medicine professor of infectious disease and vaccine advocate, called the new study an advance over research he published last year that identified “15 hotspots” of vaccine exemptions among a subset of states. Harris County ranked seventh on that list.

“I think this is a nice refinement on our first attempt,” said Hotez. “It confirms the high risk of Texas counties to measles, something that we’ll need to consider seriously when planning for epidemics.”

It’s not clear what if anything can be done to mitigate this particular risk, so I’m back to wondering how much I should worry about it. Keep working to close the gap in vaccination rates, I guess. It annoys the crap out of me that we have to worry about this sort of thing in 2019, but here we are.

The “Texas Serengeti”

How cool is this?

During the Great Depression, some unemployed Texans were put to work as fossil hunters. The workers retrieved tens of thousands of specimens that have been studied in small bits and pieces while stored in the state collections of The University of Texas at Austin for the past 80 years.

Now, decades after they were first collected, a UT researcher has studied and identified an extensive collection of fossils from dig sites near Beeville, Texas, and found that the fauna make up a veritable “Texas Serengeti” – with specimens including elephant-like animals, rhinos, alligators, antelopes, camels, 12 types of horses and several species of carnivores. In total, the fossil trove contains nearly 4,000 specimens representing 50 animal species, all of which roamed the Texas Gulf Coast 11 million to 12 million years ago.

A paper describing these fossils, their collection history and geologic setting was published April 11 in the journal Palaeontologia Electronica.

“It’s the most representative collection of life from this time period of Earth history along the Texas Coastal Plain,” said Steven May, the research associate at the UT Jackson School of Geosciences who studied the fossils and authored the paper.

In addition to shedding light on the inhabitants of an ancient Texas ecosystem, the collection is also valuable because of its fossil firsts. They include a new genus of gomphothere, an extinct relative of elephants with a shovel-like lower jaw, and the oldest fossils of the American alligator and an extinct relative of modern dogs.

The fossils came into the university’s collection as part of the State-Wide Paleontologic-Mineralogic Survey that was funded by the Works Progress Administration (WPA), a federal agency that provided work to millions of Americans during the Great Depression. From 1939 to 1941, the agency partnered with the UT Bureau of Economic Geology, which supervised the work and organized field units for collecting fossils and minerals across the state.

Despite lasting only three years, the survey found and excavated thousands of fossils from across Texas including four dig sites in Bee and Live Oak counties, with the majority of their finds housed in what is now the Texas Vertebrate Paleontology Collections at the Jackson School Museum of Earth History. Over the years, a number of scientific papers have been published on select groups of WPA specimens. But May’s paper is the first to study the entire fauna.

You can see the paper here, though it’s pretty dense. One of the things May realized in studying the bones is that the fossil hunters of eighty years ago mostly collected big specimens. So, he went back to the original sites in Bee and Live Oak Counties and did some more detailed work, finding a bunch of remains from smaller animals. That helped fill in the gaps, and there are still a bunch more specimens from the original finds yet to be studied. And all of this was part of a public works project designed to provide jobs for people still unemployed from the Great Depression. Like I said, how cool is that? Link via Gizmodo.

Senior stoners

Makes a lot of sense, really.

Most states now have legal medical marijuana, and 10 of them, including California, allow anyone 21 or older to use pot recreationally. The federal government still outlaws the drug even as acceptance increases. The 2018 General Social Survey, an annual sampling of Americans’ views, found a record 61 percent back legalization, and those 65 and older are increasingly supportive.

Indeed, many industry officials say the fastest-growing segment of their customer base is people like Atkin — aging baby boomers or even those a little older who are seeking to treat the aches and sleeplessness and other maladies of old age with the same herb that many of them once passed around at parties.

“I would say the average age of our customers is around 60, maybe even a little older,” said Kelty Richardson, a registered nurse with the Halos Health clinic in Boulder, Colorado, which provides medical examinations and sells physician-recommended cannabis through its online store.

Its medical director, Dr. Joseph Cohen, conducts “Cannabis 101” seminars at the nearby Balfour Senior Living community for residents who want to know which strains are best for easing arthritic pain or improving sleep.

Relatively little scientific study has verified the benefits of marijuana for specific problems. There’s evidence pot can relieve chronic pain in adults, according to a 2017 report from the National Academies of Sciences, Engineering and Medicine, but the study also concluded that the lack of scientific information poses a risk to public health.

[…]

People Lee’s age — 65 and over — are the fastest-growing segment of the marijuana-using population, said Dr. Gary Small, professor of psychiatry and aging at the University of California, Los Angeles.

He believes more studies on the drug’s effects on older people are needed. And while it may improve quality of life by relieving pain, anxiety and other problems, he said, careless, unsupervised use can cause trouble.

“We know that cannabis can cause side effects, particularly in older people,” he said. “They can get dizzy. It can even impair memory if the dose is too high or new ingredients are wrong. And dizziness can lead to falls, which can be quite serious.”

Richardson said Colorado saw an uptick in hospital visits by older users soon after the state legalized cannabis in 2012. The problem, he said, was often caused by novices downing too many edibles.

I don’t often blog about stories from other states, but with the Lege in session and efforts continuing to expand marijuana legalization here, this seemed useful to note. I’ll say this much, the people described in this story – mostly white people over the age of 60 – is a pretty good representation of the Republican Party base here in Texas (and elsewhere, to be honest). Given that the single biggest impediment to loosening the marijuana laws in Texas is Dan Patrick, any real progress in the short term is going to have to come from his voters telling him they want to see progress on this front. Longer term, we can try to use this issue (among many others) to boot him out of office in 2022, but between now and then is at least one more legislative session. If you want better pot laws in this state, get your old relatives to call Dan Patrick’s office and tell him that’s what they want, too.
