Artificial Intelligence Used To Search for the Next SARS-COV-2 – SciTechDaily

Daniel Becker, an assistant professor of biology in the University of Oklahomas Dodge Family College of Arts and Sciences, has been leading a proactive modeling study over the last year and a half to identify bat species that are likely to carry betacoronaviruses, including but not limited to SARS-like viruses.

The study Optimizing predictive models to prioritize viral discovery in zoonotic reservoirs, which was published by Lancet Microbe, was guided by Becker; Greg Albery, a postdoctoral fellow at Georgetown Universitys Bansal Lab; and Colin J. Carlson, an assistant research professor at Georgetowns Center for Global Health Science and Security.

It also included collaborators from the University of Idaho, Louisiana State University, University of California Berkeley, Colorado State University, Pacific Lutheran University, Icahn School of Medicine at Mount Sinai, University of Glasgow, Universit de Montral, University of Toronto, Ghent University, University College Dublin, Cary Institute of Ecosystem Studies, and the American Museum of Natural History.

Becker and colleagues study is part of the broader efforts of an international research team called the Verena Consortium (viralemergence.org), which works to predict which viruses could infect humans, which animals host them, and where they could emerge. Albery and Carlson were co-founders of the consortium in 2020, with Becker as a founding member.

Despite global investments in disease surveillance, it remains difficult to identify and monitor wildlife reservoirs of viruses that could someday infect humans. Statistical models are increasingly being used to prioritize which wildlife species to sample in the field, but the predictions being generated from any one model can be highly uncertain. Scientists also rarely track the success or failure of their predictions after they make them, making it hard to learn and make better models in the future. Together, these limitations mean that there is high uncertainty in which models may be best suited to the task.

In this study, researchers used bat hosts of betacoronaviruses, a large group of viruses that includes those responsible for SARS and COVID-19, as a case study for how to dynamically use data to compare and validate these predictive models of likely reservoir hosts. The study is the first to prove that machine learning models can optimize wildlife sampling for undiscovered viruses and illustrates how these models are best implemented through a dynamic process of prediction, data collection, validation and updating.

In the first quarter of 2020, researchers trained eight different statistical models that predicted which kinds of animals could host betacoronaviruses. Over more than a year, the team then tracked discovery of 40 new bat hosts of betacoronaviruses to validate initial predictions and dynamically update their models. The researchers found that models harnessing data on bat ecology and evolution performed extremely well at predicting new hosts of betacoronaviruses. In contrast, cutting-edge models from network science that used high-level mathematics but less biological data performed roughly as well or worse than expected at random.

Importantly, their revised models predicted over 400 bat species globally that could be undetected hosts of betacoronaviruses, including not only in southeast Asia but also in sub-Saharan Africa and the Western Hemisphere. Although 21 species of horseshoe bats (in the Rhinolophusgenus) are known to be hosts of SARS-like viruses, researchers found at least two-fourths of plausible betacoronavirus reservoirs in this bat genus might still be undetected.

One of the most important things our study gives us is a data-driven shortlist of which bat species should be studied further, said Becker, who adds that his team is now working with field biologists and museums to put their predictions to use. After identifying these likely hosts, the next step is then to invest in monitoring to understand where and when betacoronaviruses are likely to spill over.

Becker added that although the origins of SARS-CoV-2 remain uncertain, the spillover of other viruses from bats has been triggered by forms of habitat disturbance, such as agriculture or urbanization.

Bats conservation is therefore an important part of public health, and our study shows that learning more about the ecology of these animals can help us better predict future spillover events, he said.

School Closures Were a Catastrophic Error. Progressives Still Havent Reckoned With It. – New York Magazine

Recently, Nate Silver found himself in the unenviable role of main character of the day on Twitter because he proposed that school closures were a disastrous, invasion-of-Iraq magnitude (or perhaps greater) policy decision. The comparison generated overwhelming anger and mockery, and it is not an easy one to defend: A fiasco that led to hundreds of thousands of deaths and rearranged the regional power structure is a very high bar to clear. Weighing policy failures in such utterly different realms to each other is so inherently difficult that any discussion quickly devolves into Could Superman beat up Mighty Mouse? territory.

But these complications do not fully explain the sheer rage generated by Silver. The furnace-hot backlash seemed to be triggered by Silvers assumption that school closings were not only a mistake a possibility many progressives have quietly begun to accept but an error of judgment that was sufficiently consequential and foreseeable that we cant just shrug it off as a bad dice roll. It was a historic blunder that reveals some deeper flaw in the methods that produced it and which demands corrective action.

That unnerving implication has a mounting pile of evidence to support it. It is now indisputable, and almost undisputed, that the year and a quarter of virtual school imposed devastating consequences on the students who endured it. Studies have found that virtual school left students nearly half a year behind pace, on average, with the learning loss falling disproportionately on low-income, Latino, and Black students. Perhaps a million students functionally dropped out of school altogether. The social isolation imposed on kids caused a mental health state of emergency, according to the American Academy of Pediatrics. The damage to a generation of childrens social development and educational attainment, and particularly to the social mobility prospects of its most marginalized members, will be irrecoverable.

It is nearly as clear that these measures did little to contain the pandemic. Children face little risk of adverse health effects from contracting COVID, and theres almost no evidence that towns that kept schools open had more community spread.

In the panicked early week of the pandemic, the initial decision to close schools seemed like a sensible precaution. Authorities drew on the closest example at hand, the 1918 Spanish flu, which was contained by closing schools.

But in relatively short order, growing evidence showed that the century-old precedent did not offer much useful guidance. While the Spanish flu was especially deadly for children, COVID-19 is just the opposite. By the tail end of spring 2020, it was becoming reasonably clear both that remote education was failing badly and that schools could be reopened safely.

What happened next was truly disturbing: The left by and large rejected this evidence. Progressives were instead carried along by two predominant impulses. One was a zero-COVID policy that refused to weigh the trade-off of any measure that could even plausibly claim to suppress the pandemic. The other was deference to teachers unions, who were organizing to keep schools closed. Those strands combined into a refusal to acknowledge the scale or importance of losing in-person learning with a moralistic insistence that anybody who disagreed was callous about death or motivated by greed.

Social scientists have measured the factors that drove schools to stay closed last year. One study found schools with unionized teachers, more of which were located in more Democratic-voting districts, were more likely to remain all virtual. Another likewise found local political partisanship and union strength, rather than the local severity of COVID, predicted school closing.

It is always easier to diagnose these pathologies when they are taking place on the other side. Youve probably seen the raft of papers showing how vaccine uptake correlates with Democratic voting and COVID deaths correlate with Republican voting. Perhaps you have marveled at the spectacle of Republican elites actively harming their own audience. But the same thing Fox News hosts were doing to their elderly supporters, progressive activists were doing to their sides young ones.

In a big country, there are always going to be crazy people at the margins. You can measure the health of the parties by the degree to which crazy ideas are taken up by powerful people. (This, of course, is why the Republican Party handing the most powerful job in the world to a conspiracy theorist is the grimmest possible sign.) But the Democratic Partys internal debate on school closings was making room at the table for some truly unhinged ideas. The head of the largest states most powerful teachers union insisted on the record there is no such thing as learning loss and described plans to reopen schools as a recipe for propagating structural racism.

Within blue America, transparently irrational ideas like this were able to carry the day for a disturbingly long period of time. In recent days, Angie Schmitt and Rebecca Bodenheimer have both written essays recounting the disorienting and lonely experience they had watching their friends and putative political allies denounce them for supporting a return to in-person learning. Bodenheimers account is especially vivid:

Parents who advocated for school reopening were repeatedly demonized on social media as racist and mischaracterized as Trump supporters. Members of the parent group I helped lead were consistently attacked on Twitter and Facebook by two Oakland moms with ties to the teachers union. They labeled advocates calls for schools reopening white supremacy, called us Karens, and even bizarrely claimed we had allied ourselves with Marjorie Taylor Greenes transphobic agenda.

The fevered climate of opinion ruled out cost-benefit thinking and instead framed the question as a simple moral binary, with the well-being of public schoolchildren somehow excluded from the calculus. Social scientists like Emily Oster who spoke out about the evidence on schools and COVID became hate targets on the left, an intimidating spectacle for other social scientists who might have thought about speaking up.

The failed experiment finally came to an end in the fall of 2021. (A handful of districts have shut down during the Omicron wave, but this is mainly a temporary response to staff shortages rather than another effort to stop community spread.) The Chicago Teachers Union, one of the more radical unions, did stage a strike, but it was met with firm opposition from Chicago mayor Lori Lightfoot and ended quickly.

But the source of the sentiment has not disappeared. The Democratic Partys left-wing vanguard is continuing to flay critics of school closings as neoliberal ghouls carrying out the bidding of the billionaire class. Bernie Sanders aide Elizabeth Pancotti claims that the loudest and most ardent supporters of keeping schools oepn [sic] (& those who dismiss legit concerns about teacher/child health risks) are largely those with remote work options/resources for alternative child care arrangements, as if only some selfish motive could explain the desire of an American liberal to maintain public education. A story in Vice praises a student walkout in New York as a national model.

The ideas that produced the catastrophic school-closing era may have suffered a setback, but its strongest advocates hardly feel chastened. Whether educational achievement can or should be measured at all remains a very live debate within the left.

Most progressives arent insisting on refighting the school closing wars. They just want to quietly move on without anybody admitting anybody did anything wrong.

One of the grievances that critics of the Iraq War nursed after the debacle became clear was the failure of the political Establishment to draw any lessons broader than dont invade Iraq without an occupation plan. Their anger was not unfounded. The catastrophe happened in part because the structure of the debate allowed too many uninformed hawkish voices and ignored too many informed dovish ones. (As a chastened Iraq War supporter myself, Ive grown far more cautious about wading into foreign-policy debates for which I lack adequate understanding.)

Many liberals are complaining that the recent debates over short-term closings are creating a hysterical overreaction from people still angry about the 2020-21 school shutdown. Perhaps a first step to building trust that we are not planning to repeat a catastrophic mistake is to admit the mistake in the first place.

How progressives might be left in the lurch – liherald.com

By Ronald J. Rosenberg

When U.S. Rep. Tom Suozzi announced his Democratic primary run against Gov. Kathy Hochul, it may have seemed like a DAmato moment.Alfonse DAmato, then the Town of Hempstead supervisor, saw a glimmer of political daylight in 1980, when he decided to reach for the political gold ring of U.S. senator from New York. Defeating the legendary three-term incumbent Jacob Javits was deemed impossible by every political pundit and commentator, and you wouldve assumed that not even the bookies would take your bet. Yet DAmato successfully navigated every political rapid to secure victory, a win that stands to this day as testimony to astute political analysis, hard work and an indomitable belief in oneself. When Suozzi first announced his intention to run against Hochul, he rightly assumed that state Attorney General Letitia James would remain a Democratic primary candidate for governor. Given her left-wing credentials, combined with the progressive candidate for that office, Jumaane Williams, Suozzi reasoned that moderate Democrats would look for a safe house from which to escape the Democrats lurch to the left. He certainly has the credentials to be that moderate. But with James backing out of the race, the political threat from the left that Suozzi had expected to help rally centrist Democrats evaporated. Williams doesnt have the recognition, sufficient base or fundraising capabilities for a credible statewide race. That leaves Hochul in a powerful place, because she has the means to outflank Suozzi on any number of fronts.

Paul Krugman: Why are progressives hating on antitrust? – Berkshire Eagle

Inflation has become a big issue for the U.S. economy and, of course, a big political headache for the Biden administration. But while many people have been urging President Joe Biden to focus on inflation, there have been many fewer suggestions about what he might actually do. (Wander around the White House muttering, Im focused, Im focused?) For the most part, controlling inflation is now a matter for monetary policy, and the main thing that Biden can do is let the technocrats who control money do their job which means not engaging in Trump-style haranguing of the Federal Reserve.

One thing the Biden administration has been doing, however, is trying to toughen up antitrust policy, arguing that highly concentrated ownership in many industries largely a result of decades of lax regulation is helping keep prices high and possibly contributing to recent inflation.

Id describe this initiative as controversial, except that theres hardly any controversy, at least in the media: Bidens linkage of monopoly power to inflation is facing vehement, almost hysterical, criticism from all sides, including many progressive commentators. And I find that vehemence puzzling; I think it says more about the commentators than it does about the administration.

Lets stipulate that monopolies arent the reason inflation shot up in 2021 because there was already plenty of monopoly power in America back in 2020.

True, profit margins, as measured by the share of profits in gross domestic product, have increased quite a lot recently. Most of that rise, however, probably reflects big returns to companies, like shippers, that happen to own crucial assets at a time of supply chain bottlenecks. Its possible, as Sen. Elizabeth Warren has suggested, that some companies are using general inflation as an excuse to jack up prices, abusing their monopoly power in ways that might have provoked a backlash in normal times; thats certainly not a crazy argument, and making it doesnt make Warren the second coming of Hugo Chavez. Still, such behavior cant explain more than a small fraction of current inflation.

But as far as I can see, the Biden administration and its allies arent claiming otherwise. Theyre simply emphasizing monopoly power because its one thing they might be able to do something about.

And where is the policy harm? On one side, toughening up antitrust enforcement in sectors like meatpacking is something the U.S. government should be doing in any case. On the other side, theres no hint that the administrations anti-monopoly rhetoric will lead to irresponsible policies elsewhere.

As I said, all indications are that Biden and company will leave the Fed alone as it raises interest rates in an effort to cool demand. And I havent seen any important Democratic figure, inside or outside the administration, calling for Richard Nixon-style price controls. The most interventionist policy that seems remotely possible would be something like John F. Kennedys jawboning of the steel industry after an obviously coordinated jump in steel prices and its hard to imagine Biden sounding nearly as hard-line and critical of big business as Kennedy did.

So why the barrage of criticism, not just from the right which was to be expected but from the center and even the center-left?

I dont really know the answer, but I have a few suspicions.

Part of the problem, I think, is an obsession with intellectual purity. Some policy wonks outside the administration apparently expect the policy wonks inside the administration many of them friends and former colleagues to keep sounding exactly the way they did when they werent political appointees. But look, thats not the way the world works. Political appointees are supposed to serve the politicians who appointed them. Dishonesty or gross misrepresentation of reality isnt OK, but emphasizing the good things ones employers are trying to do is OK and part of the job.

Beyond that, it sure looks as if many people who consider themselves progressive are made deeply uncomfortable by anything that sounds populist even when a bit of populist outrage is entirely justified by the facts. Imagine the reaction if Biden gave a speech sounding anything like Kennedy on the steel companies. How many Democratic-leaning economists would have fainting spells?

So heres my suggestion: Give Biden and his people a break on their antitrust crusade. It wont do any harm. It wont get in the way of the big stuff, which is mostly outside Bidens control in any case.

At worst, administration officials will be using inflation as an excuse to do things they should be doing. And they might even have a marginal impact on inflation itself.
