Readers ask about exoplanets, spider silk and water beetles

cover of August 27, 2020 issue

Faraway view

Astronomers snapped the first photo of a solar system with a sunlike star and two exoplanets, Lisa Grossman reported in “A weird solar system cousin makes its photographic debut” (SN: 8/29/20, p. 5).

“At the scale of the picture, both p­lanets — massive as they are — should appear as point sources, so I assume their spherical appearance is due to the light collection method for this direct imaging,” reader Jean Asselin wrote.

Asselin is correct that the system is so far away that scientists cannot physically resolve any of the planets, says Alexander Bohn, an astronomer at Leiden University in the Netherlands. Both of the planets have no spatial size as seen from Earth. “That both have a physical diameter in the image is just caused by the optical response of an imaging device to a point source,” Bohn says. “If you image the night sky with your smartphone camera, the stars also have a finite size of pixels in your image, even though they are point sources for both you and your smartphone.”

Webicillin?

Some spider webs are coated in neurotoxins that may paralyze prey, Christie Wilcox reported in “Orb weavers may spin poisonous webs” (SN: 8/29/20, p. 18).

The story reminded reader Renata Riegler of a bit of medical folklore: S­pider webs were said to be used to dress wounds. “The paralyzing or antimicrobial properties … could have helped the healing,” Riegler wrote.

Spider webs may have been used for centuries to dress wounds. The practice even is mentioned in Shakespeare’s A Midsummer Night’s Dream: “I shall desire you of more acquaintance, good Master Cobweb: If I cut my finger, I shall make bold of you.” Spider silk is coated with chemicals that might promote blood clotting, prevent infection and speed healing, though scientific evidence for these properties is sparse, says associate editor Cassie Martin. Today, engineers are investigating spider silk as a drug delivery method and as scaffolding for tissue repair, she says.

Beetlemania

A water beetle eaten by a pond frog scurried through the frog’s digestive tract and emerged out the backside unscathed, Jonathan Lambert reported in “Eaten beetle exits the other end alive” (SN: 8/29/20, p. 18). The story amazed readers on Twitter. @JoePoutous likened the beetle’s journey to the tunnel of t­error scene in the 1971 film Willy Wonka & the Chocolate Factory. @Rogie_The_Medic suggested a new name for the insect: fecal walking beetle.

Seeing a bright future for science in these innovators

 One of the many joys of being editor in chief of Science News is learning about remarkable work being done by younger scientists. This year’s SN 10: Scientists to Watch honorees, who are profiled in this issue, are tackling some of the biggest challenges facing our world.

The search for the next SN 10 class starts in early January, when we contact Nobel Prize winners, members of the National Academy of Sciences and previous SN 10 honorees and ask for nominations. With those recommendations, we do our own research, checking out scientists’ CVs, publications and websites.

That portfolio then goes to Science News writers who cover those beats. We ask our writers to help us narrow down a very long list of people, all of whom are doing significant science and worthy of recognition. The aim is to find people who are making important discoveries, approaching a big problem with novel insights or shaking up their field.

I get to join in the next phase, when a small group of editors makes the final very difficult decisions. Once we’ve chosen the 10 finalists and double-checked their eligibility, we assign reporters to write short profiles. That’s no easy task; these researchers are so interesting we could write a very long story on each of them. But our goal is to offer a lively introduction, rather than a tome. We still take pains to put each scientist’s work in context. “The ‘why’ is interesting,” says Elizabeth Quill, Science News’ special projects editor and leader of this effort. “Why something as seemingly simple as the size of the proton is hard to know is a fascinating concept.”

I loved learning about Phiala Shanahan, a 29-year-old theoretical physicist at MIT who was shocked to discover while a graduate student that scientists disagreed on the size of the proton. That drove her to become adept at calculating the influence of gluons, which help keep protons intact. I’m inspired by Zhongwen Zhan, a 33-year-old seismologist at Caltech who wants to put fiber-optic cables to work as an earthquake early warning system. And since I have relatives in Oregon struggling with terrible air pollution caused by wildfires, I’m grateful for Emily Fischer, a 39-year-old atmospheric chemist at Colorado State University who built a collaborative network of researchers to study the enigmatic components in wildfire smoke, which are surprisingly not well known. It’s an urgent mission at a time when the western United States is contending with massive fires and choking smoke. “There’s so much science behind what people are experiencing in these devastating circumstances,” Quill says.

These researchers also have interests that go beyond the lab bench. Fischer, for one, has built a network to mentor undergraduate women in the geosciences. The program reaches more than 300 women at institutions across the United States. She encourages her own mentees to go after big, bold questions. “It’s OK to be wrong, and it’s OK to take risks,” she told staff writer Jonathan Lambert.

We hope you’ll enjoy getting acquainted with these remarkable young scientists and following their exploits in the years to come. I expect big things from them.

White House Testing Regimen Did Not Protect the President

President Donald Trump’s COVID-19 diagnosis is raising fresh questions about the White House’s strategy for testing and containing the virus for a president whose cavalier attitude about the coronavirus has persisted since it landed on American shores.

The president has said others are tested before getting close to him, appearing to hold it as an iron shield of safety. He has largely eschewed mask-wearing and social distancing in meetings, travel and public events, while holding rallies for thousands of often maskless supporters. 

The Trump administration has increasingly pinned its coronavirus testing strategy for the nation on antigen tests, which do not need a traditional lab for processing and quickly return results to patients. But the results are less accurate than those of the slower PCR tests. 

Testing “isn’t a ‘get out of jail free’ card,” said Dr. Alan Wells, medical director of clinical labs at the University of Pittsburgh Medical Center and creator of its test for the novel coronavirus. In general, antigen tests can miss up to half the cases that are detected by polymerase chain reaction tests, depending on the population of patients tested, he said.

The White House said the president’s diagnosis was confirmed with a PCR test but declined to say which test delivered his initial result. The White House has been using a new antigen test from Abbott Laboratories to screen its staff for COVID-19, according to two administration officials. 

The test, known as BinaxNOW, received an emergency use authorization from the Food and Drug Administration in August. It produces results in 15 minutes. Yet little is independently known about how effective it is. According to the company, the test is 97% accurate in detecting positives and 98.5% accurate in identifying those without disease. Abbott’s stated performance of its antigen test was based on examining people within seven days of COVID symptoms appearing.

The president and first lady have both had symptoms, according to White House Chief of Staff Mark Meadows and the first lady’s Twitter account. The president was admitted to Walter Reed National Military Medical Center on Friday evening “out of an abundance of caution,” White House Press Secretary Kayleigh McEnany said in a statement.

Vice President Mike Pence is also tested daily for the virus and tested negative, spokesperson Devin O’Malley said Friday, but he did not respond to a follow-up question about which test was used.

Trump heavily promoted another Abbott rapid testing device, the ID NOW, earlier this year. But that test relies on different technology than the newer Abbott antigen test.  

“I have not seen any independent evaluation of the Binax assay in the literature or in the blogs,” Wells said. “It is an unknown.” 

The Department of Health and Human Services announced in August that it had signed a $760 million contract with Abbott for 150 million BinaxNOW antigen tests that are now being distributed to nursing homes and historically black colleges and universities, as well as to governors to help inform decisions about opening and closing schools. The Big Ten football conference has also pinned playing hopes on the deployment of antigen tests following Trump’s political pressure

However, even senior federal officials concede that a test alone isn’t likely to stop the spread of a virus that has sickened more than 7 million Americans.

“Testing does not substitute for avoiding crowded indoor spaces, washing hands, or wearing a mask when you can’t physically distance; further, a negative test today does not mean that you won’t be positive tomorrow,” Adm. Brett Giroir, the senior HHS official helming the administration’s testing effort, said in a statement at the time.

Trump could be part of a “super-spreading event,” said Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

Given the timing of Trump’s positive test — which he announced on Twitter early Friday — his infection “likely happened five or more days ago,” Osterholm said. “If so, then he was widely infectious as early as Tuesday,” the day of the first presidential debate in Cleveland.

Other experts say it’s too soon to say whether Trump was infected in a super-spreader event. “The president and his wife have had many exposures to many people in enclosed venues without protection,” so they could have been infected at any number of places, said Dr. William Schaffner, an infectious disease specialist at the Vanderbilt University School of Medicine. 

Although Democratic presidential candidate and former Vice President Joe Biden tested negative for the virus with a PCR test Friday, experts note that false negative results are common in the first few days after infection. Test results over the next several days will yield more useful information.

It can take more than a week for the virus to reproduce enough to be detected, Wells said: “You are probably not detectable for three, five, seven, even 10 days after you’re exposed.” 

In Minnesota, where Trump held an outdoor campaign rally in Duluth with hundreds of attendees Wednesday, health officials warned that a 14-day quarantine is necessary, regardless of test results.

“Anyone who was a direct contact of President Trump or known COVID-19 cases needs to quarantine and should get tested,” the Minnesota Department of Health said.

Ongoing lapses in test result reporting could hamper efforts to track and isolate sick people. As of Sept. 10, 21 states and the District of Columbia were not reporting all antigen test results, according to a KHN investigation, a lapse in reporting that officials say leaves them blind to disease spread. Since then, public health departments in Arizona, North Carolina and South Dakota all have announced plans to add antigen testing to their case reporting.

Requests for comment to the D.C. Department of Health were referred to Mayor Muriel Bowser’s office, which did not respond. District health officials told KHN in early September that the White House does not report antigen test results to them — a potential violation of federal law under the CARES Act, which says any institution performing tests to diagnose COVID-19 must report all results to local or state public health departments.

Dr. Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security, said it’s not surprising that Trump tested positive, given that so many of his close associates — including his national security adviser and Secret Service officers —have also been infected by the virus.

“When you look at the number of social contacts and travel schedules, it’s not surprising,” Adalja said.

El sistema de pruebas para COVID de la Casa Blanca no protegió al presidente

El diagnóstico de COVID-19 del presidente Donald Trump está generando nuevas preguntas sobre la estrategia de la Casa Blanca para realizar pruebas y contener la propagación del virus, con un presidente que ha tenido una actitud arrogante desde que el coronavirus aterrizó en suelo estadounidense.

El presidente ha dicho que las personas con las que se reúne se hacen la prueba, como para generar un escudo de seguridad. Pero él mismo ha evitado casi siempre usar máscara y distanciarse socialmente en reuniones, viajes y eventos públicos, mientras organiza mitines para miles de simpatizantes, que tampoco usan tapabocas.

La estrategia de pruebas para COVID de la Administración Trump se basa en los tests de antígenos, que no necesitan un laboratorio tradicional para procesar y obtener resultados rápidamente. Pero estos resultados son menos precisos que los de las pruebas de PCR, que llevan más tiempo.

Las pruebas “no son una salvoconducto”, dijo el doctor Alan Wells, director médico de laboratorios clínicos del Centro Médico de la Universidad de Pittsburgh y creador de su propia prueba para el coronavirus. En general, las pruebas de antígenos pueden pasar por alto hasta la mitad de los casos detectados por las pruebas de reacción en cadena de la polimerasa, dependiendo de la población de pacientes examinados, agregó.

La Casa Blanca dijo que el diagnóstico del presidente se confirmó con una prueba de PCR, pero se negó a decir cuál fue la prueba que se usó para el resultado inicial. La administración ha estado utilizando una nueva prueba de antígeno del laboratorio Abbott para detectar COVID-19 en su personal, según dos funcionarios.

La prueba, conocida como BinaxNOW, recibió una autorización de uso de emergencia de la Administración de Alimentos y Medicamentos (FDA) en agosto. Produce resultados en 15 minutos. Sin embargo, se sabe poco de forma independiente sobre su eficacia.

Según la compañía, la prueba tiene una precisión del 97% en la detección de casos positivos y una precisión del 98,5% en la identificación de personas sin enfermedad. El desempeño declarado de Abbott de su prueba de antígeno se basó en examinar a las personas dentro de los siete días posteriores a la aparición de síntomas de COVID.

Tanto el presidente como la primera dama han tenido síntomas, según Mark Meadows, jefe de gabinete de la Casa Blanca, y la cuenta de Twitter de Melania Trump. El presidente fue admitido en el hospital militar Walter Reed el viernes 2 de septiembre por la noche “por precaución”, dijo la secretaria de prensa de la Casa Blanca, Kayleigh McEnany, en un comunicado.

El vicepresidente Mike Pence también se somete a pruebas diarias para detectar el virus y dio negativo, dijo el vocero Devin O’Malley, pero no respondió a una pregunta de seguimiento sobre qué prueba se utilizó.

Trump promovió en gran medida otra prueba rápida de Abbott, ID NOW, a principios de este año. Pero esa prueba se basa en una tecnología diferente a la nueva prueba de antígenos del mismo laboratorio.

“No he visto ninguna evaluación independiente del ensayo Binax en la literatura o en blogs”, dijo Wells. “Es un desconocido”.

El Departamento de Salud y Servicios Humanos (HHS) anunció en agosto que había firmado un contrato de $760 millones con Abbott por 150 millones de pruebas de antígeno BinaxNOW, que ahora se están distribuyendo a hogares de adultos mayores y universidades históricamente afroamericanas, así como a los gobernadores para ayudar a decidir sobre reaperturas, o cierres, de escuelas.

Sin embargo, incluso los altos funcionarios federales admiten que no es probable que una prueba por sí sola detenga la propagación de un virus que ha enfermado a más de 7 millones de estadounidenses.

“Las pruebas no sustituyen evitar espacios interiores abarrotados, lavarse las manos o usar una máscara; además, una prueba negativa hoy no significa que no será positiva mañana”, dijo el almirante Brett Giroir, el alto funcionario del HHS que dirigió el esfuerzo de pruebas de la administración, en un comunicado en ese momento.

Trump podría ser parte de un “evento de superdifusión”, dijo el doctor Michael Osterholm, director del Centro de Investigación y Política de Enfermedades Infecciosas de la Universidad de Minnesota.

Dado el momento de la prueba positiva de Trump, que anunció en Twitter la madrugada del viernes 2, su infección “probablemente ocurrió hace cinco o más días”, dijo Osterholm. “Si es así, entonces ya era muy contagioso el martes”, el día del primer debate presidencial en Cleveland.

Al menos siete personas que asistieron al anuncio de Trump de su nominación de la jueza Amy Coney Barrett para la Corte Suprema, el 26 de septiembre, han dado positivo desde entonces. Entre ellos: la ex asesora de Trump, Kellyanne Conway, los senadores republicanos Mike Lee y Thom Tillis, y el presidente de la Universidad de Notre Dame, el reverendo John Jenkins.

Los expertos dicen que es demasiado pronto para decir cómo se infectó Trump. “El presidente y su esposa han estado expuestos a muchas personas en lugares cerrados sin protección”, dijo el doctor William Schaffner, especialista en enfermedades infecciosas de la Escuela de Medicina de la Universidad de Vanderbilt.

Aunque el candidato presidencial demócrata Joe Biden dio negativo para el virus con una prueba de PCR el viernes 2, expertos señalan que los falsos negativos son comunes en los primeros días después de la infección. Los resultados de pruebas durante los próximos días proporcionarán información más útil.

El virus puede tardar más de una semana en reproducirse lo suficiente como para ser detectado, dijo Wells: “Probablemente no seas detectable durante tres, cinco, siete, incluso 10 días después de estar expuesto”.

En Minnesota, donde Trump realizó un mitin de campaña al aire libre en Duluth con cientos de asistentes el miércoles 30 de septiembre, funcionarios de salud advirtieron que es necesaria una cuarentena de 14 días, independientemente de los resultados de las pruebas.

Las fallas continuas en los informes de los resultados de las pruebas podrían obstaculizar los esfuerzos para rastrear y aislar a las personas enfermas. Hasta el 10 de septiembre, 21 estados y el Distrito de Columbia no informaban todos los resultados de las pruebas de antígenos, según una investigación de KHN. Un lapso en los informes que, según los funcionarios, les impide visualizar con claridad la propagación de la enfermedad. Desde entonces, los departamentos de salud pública de Arizona, Carolina del Norte y Dakota del Sur han anunciado planes para agregar pruebas de antígenos a sus informes de casos.

Las solicitudes de comentarios al Departamento de Salud de DC se remitieron a la oficina de la alcaldesa Muriel Bowser, que no respondió. Funcionarios de salud del distrito le dijeron a KHN a principios de septiembre que la Casa Blanca no les informa los resultados de las pruebas de antígenos, una posible violación de un apartado de la Ley CARES, que indica que cualquier institución que realice pruebas para diagnosticar COVID-19 debe informar todos los resultados a las oficinas locales o departamentos estatales de salud pública.

El doctor Amesh Adalja, investigador principal del Centro de Seguridad Sanitaria de la Universidad Johns Hopkins, dijo que no es sorprendente que Trump diera positivo, dado que muchos de sus cercanos, incluidos su asesor de seguridad nacional y oficiales del Servicio Secreto, también se infectaron.

“Cuando miras la cantidad de contactos sociales y los viajes, no es sorprendente”, dijo Adalja.

Neandertal genes in people today may raise risk of severe COVID-19

Some people’s genetic inheritance from Neandertals may raise their risk of developing severe COVID-19.

A stretch of DNA on human chromosome 3 was previously found to be associated with an increased risk of developing severe disease from coronavirus infection and of being hospitalized.  Some genetic heirlooms passed down after humans interbred with Neandertals more than 50,000 years ago are known to affect immune system function and other aspects of human health even today (SN: 2/11/16). So researchers decided to see whether Neandertals and other extinct human cousins called Denisovans also share the risky region.

“I fell off my chair. It was really a surprise to see that the genetic variants were exactly the same as Neandertals’,” says evolutionary geneticist Hugo Zeberg of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the Karolinska Institute in Stockholm. Zeberg and his Max Planck colleague Svante Pääbo report the findings September 30 in Nature.

About half of people whose ancestors hail from South Asia — particularly Bangladesh — and about 16 percent of people in Europe today carry this bit of Neandertal legacy, the new study finds.

The risky DNA was identified as a COVID-19 danger zone in genome-wide association studies, or GWAS, which use statistical methods to find genetic variants that show up more often in people with a particular disease than in those without the disease. In this case, the comparison was between people who have milder forms of COVID-19 and people who required hospitalization.

This stretch on chromosome 3 contains multiple genetic variants that are almost always inherited together, forming a block known as a haplotype. Those variants aren’t necessarily the genetic tweaks that lead to more severe disease, but they flag that one or more genes in the region might be responsible for increasing susceptibility to the coronavirus. The researchers are working to figure out which genes in the region might be contributing to susceptibility, Zeberg says.

Of 13 genetic variants that make up the risky haplotype, 11 were found in the DNA of a 50,000 year-old Neandertal from Vindija Cave in Croatia (SN: 10/10/17), and three were shared with two Neandertals from the Altai mountains in Russia. Denisovans, on the other hand, didn’t carry these variants.

Although most non-Africans carry some Neandertal DNA as a relic of ancient interbreeding, inheritance of the COVID-19 susceptibility haplotype was patchy. The haplotype didn’t get passed down in East Asia, but people of South Asian ancestry were more likely to carry the Neandertal legacy. About 63 percent of people in Bangladesh have at least one copy of the disease-associated haplotype, and 13 percent have two copies (one from their mother and one from their father). For them, the Neandertal DNA might be partially responsible for increased mortality from a coronavirus infection. People of Bangladeshi origin living in the United Kingdom, for instance, are twice as likely to die of COVID-19 as the general population.

That patchwork inheritance pattern may indicate that different evolutionary pressures were at work during the haplotype’s history, says Tony Capra, an evolutionary geneticist at the University of California, San Francisco. “It’s an important lesson about genetic variation; what’s good in one place can be bad in another place.”

In Bangladesh, the haplotype may have given people an evolutionary advantage in fighting off other pathogens, such as cholera, allowing it to increase in frequency, Zeberg speculates. In East Asia, it might have been an evolutionary disadvantage when dealing with other illnesses, leading to its decline.

The results don’t mean that carrying Neandertal DNA will cause people to become severely ill — nor that not having it will protect people. East Asians generally have more Neandertal DNA than other groups (SN: 2/12/15), but didn’t inherit this risky heirloom. Still, thousands of people in China and other parts of East Asia have died of COVID-19. On the other hand, people of African descent have little to no Neandertal DNA, but Black Americans are among those at highest risk of dying of COVID-19, often for reasons that may have nothing to do with their genes (SN: 5/10/20).

Capra stresses that “with COVID-19, there’s a genetic component that is important, but social and other environmental factors are so much more important in determining risk and severity.” For instance, one of the biggest risk factors is age, with young children at the least risk and elderly people far more likely to be hospitalized or die when they contract COVID-19.

Wear a Mask. If Only It Were That Simple.

Nils Hase, a retiree who lives in Tarpon Springs, Florida, is wearing a mask and loading his Home Depot haul into his car on a recent weekday afternoon. In the store, because Home Depot insists customers and staff across the country wear masks, most faces were covered. But out here in the parking lot, in a state with a serious infection rate but no mask mandate, plenty of those masks hang down around people’s chins.

“It bothers me. They are being defiant,” Hase said. “And most of the people I see that walk in without a mask are just looking for a fight. They are asking you to ‘Just ask me. Just give me a reason to yell at you.’ I just stay away from them and keep on with my own life.”

Six and a half months after President Donald Trump declared the coronavirus emergency, COVID-19 has killed more than 207,000 Americans and infected 7.3 million, now including Trump himself and the first lady.

Scientists are warning of a larger wave of infection this winter. They agree the simplest, easiest way to fight that surge is to get most people to wear masks most of the time.

Yet the political fight over face coverings rages. It plays out on city streets, in suburban grocery stores, in rural sheriff’s offices and at the highest echelons of government — all the way to the presidential debate stage this week in Cleveland. There, most of Trump’s contingent refused to wear required masks, and one of them tested positive soon afterward. Only time will tell if they spread the infection, but their behavior is mirrored across the nation.

Hefty Price in Iowa

In April, Iowa health officials cut an agreement with Iowa University to do modeling on the impact of coronavirus. Among the data are estimates of future death rates and the projection that more than a thousand Iowans could be saved by adopting a universal mask policy.

Later that month, the researchers warned Republican Gov. Kim Reynolds not to ease restrictions aimed at curtailing the virus, saying a spike would result later in the year. They also recommended a strong policy on facial coverings, producing a report that said face shields would dramatically lower the virus’s toll.

Reynolds took none of that advice. She started easing restrictions in late April. She argued it was more important to reopen the state’s economy while encouraging people to be responsible and wear masks than to throw down a mandate she called unenforceable.

“I think the goal is to strongly encourage and recommend that people wear them,” she said in late August. “I believe that people are.”

Yet at that moment, Iowa was proving the university’s predictions true, suffering the highest infection rate in the nation. In late September, the state was one of only seven that remained in the “red zone,” averaging more than 890 new infections a day.

The governor’s intransigence on masks highlights a troubling problem. At a time when experts believe the nation needs to unite around a strategy to curb a potentially catastrophic winter, the cheapest, best option — masks — have become increasingly politicized. Even Republicans like Reynolds, who agree masks work, refuse to take the advice of their experts. They oppose mandates and favor an educational approach that many people actively resist.

Dissent Within the Trump Administration

The trouble starts at the top. The Trump administration’s leading medical advisers have testified repeatedly that masks were the country’s best tool to blunt a second wave that could be significantly deadlier than the initial spike.

Dr. Robert Redfield, director of the Centers for Disease Control and Prevention, went as far to say face coverings were a more certain bet than a vaccine if everyone would wear them.

“If we did it for six, eight, 10, 12 weeks, we’d bring this pandemic under control,” Redfield said during a Sept. 16 hearing. “They are our best defense.”

Trump contradicted him before the day was done, and just a few days earlier, as the president and his coterie did in Cleveland, Trump modeled exactly the opposite behavior. At a campaign rally of thousands in Nevada, he cheered on the mostly maskless crowd. The next day, he held a massive mask-optional indoor rally at a warehouse in Henderson, Nevada, defying state restrictions. He advised the owner (who was later fined $3,000) that he’d protect the man if the state went after him.

“I’ll be with you all the way. Don’t worry about a thing,” Trump said.

But Trump’s actions and statements are worrisome for scientists and public health experts. They have watched in horror and frustration as the president’s dismissive attitude toward masks and COVID-19 itself has gone hand in hand with growing politicization of the public health response.

Meanwhile, the White House Coronavirus Task Force, led by Vice President Mike Pence, issued a “state report” on Montana on Sept. 20 that included the suggestion that the state “consider fines for violations of face mask mandates in high transmission areas.” At a press conference, Gov. Steve Bullock, a Democrat, said fining people would not be “the Montana way.” The state is, however, one of 34 with a mask mandate in place.

Indeed, the single-strongest predictor of whether or not a state will mandate strong mask policies bears little relationship to a state’s disease problem, according to a recent study by a team at the University of Washington.

After analyzing comprehensive data on mask policies, researchers led by Chris Adolph, a professor of political science and statistics, found that having a Republican governor would predict a 30-day delay in recommending mask policies. In a state that is also ideologically conservative, the delay would be closer to 40 days. A state’s death rate or infection rate had a much weaker influence.

“Because mask mandates are far less costly than business closures or stay-at-home orders, when we started to monitor these policies in April, we hoped their adoption would be universal,” Adolph said. “Instead, we found the same pattern: Republican governors resisted mandating masks even when public health conditions called for them.”

Adolph’s research suggests Trump is at least amplifying disdain for masks and, in fact, the phenomenon has been playing out across the country, most strikingly among some of Trump’s most ardent supporters — law enforcement and extremely conservative politicians.

Anti-Mask Sheriffs

In Washington state, Florida and even Democratic California, sheriffs made headlines by taking actions in opposition to local masking guidelines.

In Washington’s Snohomish County, where the first case of COVID-19 was discovered in the United States, Sheriff Adam Fortney declared in an April Facebook post: “The impacts of COVID 19 no longer warrant the suspension of our constitutional rights.”

Democratic Gov. Jay Inslee ordered people to wear masks in public in late June, just as a summer-long rise of infections began. Lewis County Sheriff Rob Snaza responded by telling a cheering crowd outside a church, “Don’t be a sheep.” Klickitat County Sheriff Bob Songer on the radio called Inslee “an idiot” over the order.

In Florida, anti-mask resistance has been especially fierce. Again, sheriffs offered the most startling opposition. One, Marion County Sheriff Billy Woods, banned masks for his deputies and visitors to the sheriff’s department offices, though he later relented on visitors.

Even in solid-blue Los Angeles County, the sheriff’s office was reprimanded by the county inspector general because deputies refused to wear masks, in violation of public health orders.

Surprisingly, officials there who support masks were disinclined to push tough enforcement.

“One of the things in all of this is we’re not going to enforce or fine our way out of this,” L.A.’s top public health official, Dr. Muntu Davis, told reporters recently.

Researchers disagree with Davis and Reynolds, not because education doesn’t work, but because it takes a long, sustained effort.

“Developing and deploying health education programs takes time, so in emergencies where rapid compliance is essential for reducing the spread of a novel pathogen, mandates are a critical element,” said Adolph.

Tickets in Tennessee

That’s the path officials took in Nashville, Tennessee, though initially officers opted for a more lenient approach than the mayor wanted. They had to be forced to write tickets with a potential fine of $50. The police still mostly have been giving warnings — thousands on any given weekend — but they’ve also written dozens of tickets and made some arrests.

City officials credit the crackdown with curbing COVID-19, even as it ran rampant in rural Tennessee counties where there are no mask mandates. In late September, Nashville’s Davidson County had 13.5 cases per 100,000 people, while more than three dozen less populous counties had “red zone” infection rates, with more than 25 cases per 100,000 people.

Amid the conflicting messages, including where enforcement has worked, not everyone is convinced that covering your nose and mouth is something that should rise to the level of police.

“I think they have better things to do than force anybody to wear a mask,” said Jennifer Johnson, an X-ray tech in downtown Nashville. “I think it should be at your own risk, but that’s just my opinion.”

Lawsuits Plus Weekly Protests in Florida

Plenty of conservative-leaning citizens and lawmakers agree with her, to the point of suing to block mandates.

In Hillsborough County, Florida, home to Tampa, county commissioners must vote each week to renew a state of emergency that requires masks to be worn in indoor public places.

Jason Kimball, a regular speaker at those meetings opposing the order, grew so angry he started a GoFundMe campaign for a lawsuit. He hit his $5,000 goal in 24 hours.

“You can only do so much as a commission legally, without violating the state constitution and the United States Constitution,” Kimball said at a recent meeting.

Rep. Anthony Sabatini, a state lawmaker who has filed 15 similar lawsuits on behalf of others all over the state, took the case. He claims mask ordinances are an overreach by government and a violation of Florida’s privacy clause.

“The government has never done this before,” Sabatini said. “It’s never told people that they have to wear masks everywhere they go all day long, and that’s basically what it’s come to.”

A judge dismissed Sabatini’s case in Hillsborough County and several of his other lawsuits have been denied.

Like Kimball and many other mask opponents, Sabatini insists masks don’t work, saying anyone can Google it to find out.

Scientists beg to differ, and are distressed political ideology has trumped real data and made it impossible for science to dictate the best responses.

“That’s certainly been a source of frustration for those of us who work in public health,” said Joe Cavanaugh, who runs the Department of Biostatistics at the University of Iowa’s College of Public Health and helped build the modeling distributed to Gov. Reynolds.

Watching Other Countries Succeed

Dr. Ali Mokdad, a former outbreak scientist at the CDC who works for the Institute for Health Metrics and Evaluation at the University of Washington’s School of Medicine, finds it especially painful to watch other countries deal with the pandemic better than the United States.

He traveled the globe to stop outbreaks, and now other countries are using the methods he and his former colleagues at the CDC taught them.

“Why aren’t people wearing a mask? For the first time in our history, of humankind, we have a measure that is really very cheap,” he said. “You can make it at home yourself from something old you have. It saves lives. It saves the economy.”

It is doubly frustrating — and alarming — because while mask adoption had been rising over the summer, it’s recently begun to slip. The shift caused IHME to adjust upward its model of how many people would get infected and die by Jan. 1 in the United States.

“This change in the last week is due mainly to the decline in masks and the increase in mobility,” Mokdad said.

The death rate estimate has since moderated — projected this week at 372,000.

One place where mask use has declined is Iowa, where Mokdad said only 28% of people say in surveys they are always likely to wear a mask when they go out.

Scientists at the University of Iowa had been using data similar to what IHME uses for its coronavirus models. The state won’t let the university make its modeling public, but when some of its data was online, the projection was that Iowa would see more than 1,000 deaths by the end of August if no additional safety steps were taken. As of Tuesday, the state’s official toll was 1,328.

By IHME’s most recent similar estimates, more than 3,400 Iowans will die by Jan. 1. With a universal mask requirement, some 1,600 could be saved. Nationally, nearly 115,000 lives could be spared.

Winter Is Coming

Cavanaugh would welcome even a toothless mandate to spare some of those lives. “Just sending that message at the state level is, I think, an important step in emphasizing the importance of it,” said the University of Iowa researcher.

Sixteen states still do not have a mandate, all of them led by Republicans.

The especially frightening element to the anti-mask movement is that it can only worsen what scientists already warn is going to be a bad winter.

When it’s cold, the virus can survive longer on surfaces, and people are stuck indoors where it can become more concentrated in the aerosolized droplets people exhale.

“We’ve seen it in our data. We’ve seen it in other countries,” Mokdad said. “It’s very strong, and it’s going to happen in the U.S., unfortunately.”

Back in Florida, Nils Hase will keep wearing his mask.

“I’ve always believed in the science behind it,” Hase said. “It’s a virus and we need to be aware of what’s going on. People who don’t, they’re just idiots.”

This snake rips a hole in living toads’ stomachs to feast on their organs

Some snakes eat toads by politely swallowing the creatures whole. Others saw a hole in a toad’s abdomen with their teeth, shove their heads in and gorge on organs and tissues — while the amphibian is still alive.

“Toads don’t have the same feelings and can’t sense pain in the same way as we can,” says Henrik Bringsøe, an amateur herpetologist who lives in Køge, Denmark. “But still, it must be the most horrible way of dying.”

In a new study, published September 11 in Herpetozoa, Bringsøe and his Thailand-based colleagues document three such attacks on toads by small-banded kukri snakes (Oligodon fasciolatus). It’s the first time that researchers have observed this behavior in snakes, though animals like crows or raccoons eat some toads in a similar fashion.

Small-banded kukri snakes are known to use their teeth — which resemble curved kukri knives used by Nepalese Gurkha soldiers — to tear into eggs. And like most snakes, O. fasciolatus also feed by swallowing their meals whole. The snakes may use the newly described method, the researchers say, to best evade a toxin that the Asian black-spotted toad (Duttaphrynus melanostictus) secretes from glands on its neck and back (SN: 6/19/18).  

One Asian black-spotted toad was already dead when the children of coauthors Winai and Maneerat Suthanthangjai — both agricultural researchers at Loei Rajabhat University in Loei, Thailand — stumbled upon a snake feasting on its innards near the city. But the whole area was bloody, and the snake had clearly dragged its prey around. It was clear “that it had been a true battlefield,” Bringsøe says.

Two other episodes at a nearby pond involved living Asian black-spotted toads. One fight that Winai watched lasted almost three hours, as a snake battled with the toad’s toxic defenses before finally winning. A kukri snake saws into its prey using its teeth like a steak knife, he says, “slowing cutting back and forth until it can put its head in” and eat the organs.

The reptiles may attack in this manner to help them dodge a toad’s poison, Bringsøe says, but it also may be a way for the snakes to eat prey that is too large to swallow. A fourth snake was spotted by coauthor Kanjana Nimnuam, a colleague of the Suthanthangjais, swallowing a smaller black-spotted toad whole.

President of U.S. Demeans S.U.D. sufferers –

Oct. 1, 2020 – Even the Real Housewives know that kids are always off-limits. Around 20 million Americans ages 12 and older have a substance abuse disorder, according to a 2019 report from the Substance Abuse and Mental Health Services Administration. When Trump took a shot at Biden’s son on this prime-time stage, he was also firing off at them and at the tens of thousands of family members who have an addict in their lives.

With roughly 70,000 people dying per year from accidental overdoses and with alcohol use skyrocketing during the pandemic, it feels wildly callous and irresponsible for our president to “go in” on people who are struggling with a disease formally recognized by the American Medical Association.

On April 22, 1978, then-first lady of the United States Betty Ford bravely announced to the world that she was addicted to prescription medication and alcohol. Later on, she famously created the gold standard in treatment centers, the Betty Ford Center. And up until her death at age 93, she worked tirelessly to remove the stigma that many people associate with alcoholism and addiction. 

Last week when actor Dax Shepard opened up on his podcast Armchair Expert about his drug use after claiming 16 years of sobriety, he spoke about being scared — not just of having “lost his time,” but of being stigmatized. Shepard spoke candidly about how his ego was his own worst enemy, saying he had been afraid of what people would think of him if he confessed.
