Americans need to be nudged out of the pandemic

Americans need to be nudged out of the pandemic

Juliette Kayyem writes: Perhaps you’ve figured this out already: The pandemic will not have a discrete end. The coronavirus will not raise a white flag. There will be no peace treaty, no parade, no announcement from the CDC that the United States is done worrying about COVID. You will not get closure. The signs remain too mixed. The virus continues to spread, even as widening vaccine eligibility, booster shots, and improved medical treatments limit the damage the virus can do….

How record wildfires are harming human health

How record wildfires are harming human health

Nature reports: On a cool September morning in San Francisco, a group of firefighters packed their gear into a bright red van. The sickly sweet odour of pine resin from a distant blaze hung in the air as the crew prepared to battle the rapidly growing Dixie fire, on its way towards becoming the largest single wildfire in California’s history. Sweeping across the Sierra Nevada mountains, it would come to scorch more than 3,900 square kilometres before crews fully contained…

A ‘universal’ flu vaccine could bring one of the world’s longest pandemics to an end

A ‘universal’ flu vaccine could bring one of the world’s longest pandemics to an end

Matthew Hutson writes: In 2009, global health officials started tracking a new kind of flu. It appeared first in Mexico, in March, and quickly infected thousands. Influenza tends to kill the very young and the very old, but this flu was different. It seemed to be severely affecting otherwise healthy young adults. American epidemiologists soon learned of cases in California, Texas, and Kansas. By the end of April, the virus had reached a high school in Queens, where a few…

Junk food is bad for plants, too

Junk food is bad for plants, too

Anne Biklé and David R. Montgomery write: Most of us are familiar with the much-maligned Western diet and its mainstay of processed food products found in the middle aisles of the grocery store. Some of us beeline for the salty chips and others for the sugar-packed cereals. But we are not the only ones eating junk food. An awful lot of crops grown in the developed world eat a botanical version of this diet—main courses of conventional fertilizers with pesticide…

How the Western diet has derailed our evolution

How the Western diet has derailed our evolution

Moises Velesquez-Manoff writes: For the microbiologist Justin Sonnenburg, that career-defining moment—the discovery that changed the trajectory of his research, inspiring him to study how diet and native microbes shape our risk for disease—came from a village in the African hinterlands. A group of Italian microbiologists had compared the intestinal microbes of young villagers in Burkina Faso with those of children in Florence, Italy. The villagers, who subsisted on a diet of mostly millet and sorghum, harbored far more microbial diversity…

First known Covid case was vendor at Wuhan market, scientist claims

First known Covid case was vendor at Wuhan market, scientist claims

The New York Times reports: A scientist who has pored over public accounts of early Covid-19 cases in China reported on Thursday that an influential World Health Organization inquiry had most likely gotten the early chronology of the pandemic wrong. The new analysis suggests that the first known patient sickened with the coronavirus was a vendor in a large Wuhan animal market, not an accountant who lived many miles from it. The report, published on Thursday in the prestigious journal…

Covid cases are surging in Europe. America is in denial about what lies in store for it

Covid cases are surging in Europe. America is in denial about what lies in store for it

Eric Topol writes: It’s deja vu, yet again. The pandemic first hit Europe in March 2020, and Americans were in denial, thinking it wouldn’t happen here. Then, later in the year, the Alpha variant wave took hold in the United Kingdom and the United States was unprepared. This recurred with Delta in the summer of 2021. Now, in the fall of 2021, Europe is the outlier continent on the rise with Covid, with approximately 350 cases per 100,000 people and…

Largest psilocybin trial finds the psychedelic is effective in treating serious depression

Largest psilocybin trial finds the psychedelic is effective in treating serious depression

STAT reports: Eagerly awaited results of the largest-ever study of psilocybin were announced Tuesday, with Compass Pathways revealing the psychedelic drug was highly efficacious as a therapy for treatment-resistant depression. Still, the company’s stock price dropped 16.4% by the close of trading, perhaps because of safety concerns among investors. The Phase 2b study is the largest randomized, controlled, double-blind trial of psilocybin, the psychedelic compound in magic mushrooms. The company said it found that patients who were given the highest…

Should we rein cities in or embrace their biomorphic growth?

Should we rein cities in or embrace their biomorphic growth?

Josh Berson writes: Cities are hard on the body. We are all familiar now with how dense living facilitates the spread of airborne disease. But the stressors of urban life are manifold. They include air- and waterborne pollution, noise, heat, light – and an excess of social contact. Pollution represents, as a 2017 report by the Lancet Commission on pollution and health puts it, ‘the largest environmental cause of disease and premature death’ among humans, responsible, in 2015, for ‘three…

If the super-rich want to live for ever our planet is truly doomed

If the super-rich want to live for ever our planet is truly doomed

John Harris writes: Welcome to the era of immortalists: scientists, dreamers and – crucially – billionaires, who want us to think of age as a curable disease, and our final end as something that could be indefinitely postponed. According to one estimate, the revenues of the global anti-ageing industry will increase from about $200bn today to $420bn by 2030. One sure sign of its rosy prospects is the involvement of high-profile people in the US who have made vast fortunes…

Why air pollution can trigger depression

Why air pollution can trigger depression

Inverse reports: You may be breathing dirty air right now. Nine out of ten people in the world live in areas with high levels of air pollutants, according to the World Health Organization. This is a problem for physical and mental health. In addition to its well-established relationships to cancer and respiratory and heart diseases, a growing trove of scientific evidence links air pollution with depression and other mental health disorders. A study published Monday in the Proceedings of the…

An idea about safety that keeps putting us in danger

An idea about safety that keeps putting us in danger

Tim Requarth writes: Remember March of 2020, before masks? Back then, as we became aware that the coronavirus was circulating around the country at an alarming clip, packed up our offices, and pulled our kids out of in-person school, the nation’s top experts urged us not to bother covering our nose and mouths. Among the complex reasons for the hesitation was a simple one: distrust of the public. “I worry that if people put on masks, then they’ll think, OK,…

The partisan gap in Covid’s death toll is growing faster

The partisan gap in Covid’s death toll is growing faster

David Leonhardt writes: The gap in Covid’s death toll between red and blue America has grown faster over the past month than at any previous point. In October, 25 out of every 100,000 residents of heavily Trump counties died from Covid, more than three times higher than the rate in heavily Biden counties (7.8 per 100,000). October was the fifth consecutive month that the percentage gap between the death rates in Trump counties and Biden counties widened. Some conservative writers…

The brain can recall and reawaken past immune responses

The brain can recall and reawaken past immune responses

Esther Landhuis writes: Dogs that habitually hear a bell at chow time become classically conditioned to drool at the mere chime, as the physiologist Ivan Pavlov showed in the 1890s: Their brains learn to associate the bell with food and instruct the salivary glands to respond accordingly. More than a century later, in a paper published today in Cell, the neuroimmunologist Asya Rolls has shown that a similar kind of conditioning extends to immune responses. Using state-of-the-art genetic tools in…

U.S. federal appeals court freezes Biden’s vaccine rule for companies

U.S. federal appeals court freezes Biden’s vaccine rule for companies

Reuters reports: A U.S. federal appeals court issued a stay Saturday freezing the Biden administration’s efforts to require workers at U.S. companies with at least 100 employees be vaccinated against COVID-19 or be tested weekly, citing “grave statutory and constitutional” issues with the rule. The ruling from the United States Court of Appeals for the Fifth Circuit comes after numerous Republican-led states filed legal challenges against the new rule, which is set to take effect on Jan 4. In a…

Widespread coronavirus infection found in Iowa deer, new study says

Widespread coronavirus infection found in Iowa deer, new study says

The New York Times reports: A new study of hundreds of white-tailed deer infected with the coronavirus in Iowa has found that the animals probably are contracting the virus from humans, and then rapidly spreading it among one another, according to researchers. Up to 80 percent of deer sampled from April 2020 through January 2021 in the state were infected, the study indicated. Scientists said the findings pose worrisome implications for the spread of the coronavirus, although they were not…
