Nature reports: Many scientists rely on Indigenous people to guide their work — by helping them to find wildlife, navigate rugged terrain or understand changing weather trends, for example. But these relationships have often felt colonial, extractive and unequal. Researchers drop into communities, gather data and leave — never contacting the locals again, and excluding… Read More »
Science reports: One hundred and fifty years after a French neurologist first recognized a case of multiple sclerosis (MS) in a young woman with an unusual tremor, the cause of this devastating disease remains elusive. Now, a study that combed data from regular blood tests of 10 million U.S. soldiers has found the strongest evidence… Read More »
Carrie Arnold writes: In the fall of 2019, the world began one of the largest evolutionary biology experiments in modern history. Somewhere near the city of Wuhan in eastern China, a coronavirus acquired the ability to live inside humans rather than the bats and other mammals that had been its hosts. It adapted further to… Read More »
Laura Spinney writes: Isaac Newton apocryphally discovered his second law – the one about gravity – after an apple fell on his head. Much experimentation and data analysis later, he realised there was a fundamental relationship between force, mass and acceleration. He formulated a theory to describe that relationship – one that could be expressed… Read More »
Ian Stewart writes: In Isaac Asimov’s novel Foundation (1951), the mathematician Hari Seldon forecasts the collapse of the Galactic Empire using psychohistory: a calculus of the patterns that occur in the reaction of the mass of humanity to social and economic events. Initially put on trial for treason, on the grounds that his prediction encourages… Read More »
Adam Shapiro writes: It’s been nearly 30 years—a generation!—since professional science communication as a field began to seriously push back against what’s been called the knowledge deficit model (sometimes just called the “deficit model.”) (See “The Trust Fallacy,” July–August 2021.) That model describes a way of thinking about people’s understanding and acceptance of scientific knowledge,… Read More »
The New York Times reports: A spate of new studies on lab animals and human tissues are providing the first indication of why the Omicron variant causes milder disease than previous versions of the coronavirus. In studies on mice and hamsters, Omicron produced less damaging infections, often limited largely to the upper airway: the nose,… Read More »
STAT reports: The Omicron wave in the United States is upon us. If you were fortunate enough to tune out from Covid-19 news over the holidays, you’re coming back to startling reports about record high case counts and, in some places, increases in hospitalizations. The wave will crest, of course; the question is when. For… Read More »
The Wall Street Journal reports: The Food and Drug Administration last week authorized two oral antiviral medicines for the early treatment of Covid-19. But don’t get too excited. The U.S. will still have a meager treatment arsenal this winter. The U.S. has been relying on monoclonal-antibody treatments, but most don’t hold up against the Omicron… Read More »
Ars Technica reports: Thanks to unbridled greenhouse gas emissions, our planet is stitching together a climate version of Dr. Frankenstein’s monster. We still have ice from the warmer parts of the Pleistocene even as our temperature approaches the warmer Pliocene levels of 3 million years ago. Meanwhile, our CO2 level is between the Pliocene and… Read More »
STAT reports: With the world facing the latest in a seemingly endless stream of coronavirus variants — and with bullish talk from manufacturers about a need for even more vaccine shots — you wouldn’t be alone if you were wondering: Are Covid boosters always going to be a fixture in our future? The simple truth… Read More »
Live Science reports: Climate change warnings are coming thick and fast from scientists; thousands have signed a paper stating that ignoring climate change would yield “untold suffering” for humanity, and more than 99% of scientific papers agree that humans are the cause. But climate change wasn’t always on everyone’s radar. So when did humans first… Read More »
Dhruv Khullar writes: The Covid-19 pandemic, like every pandemic before it, is a story of equilibriums: between viral biology and human immune response; between news of the pathogen and fear of it; between the damage it inflicts and the social, economic, and political choices we make. A disease persists as a pandemic as long as… Read More »
Bloomberg reports: A two-shot course of Pfizer Inc.’s vaccine has just 22.5% efficacy against symptomatic infection with the omicron variant, but can thwart severe disease, according to laboratory experiments in South Africa. Researchers at the Africa Health Research Institute in Durban issued additional data on a small study released earlier this week. The research considered… Read More »
Rachel Gutman writes: Even before the arrival of Omicron, the winter months were going to be tough for parts of the United States. While COVID transmission rates in the South caught fire over the summer, the Northeast and Great Plains states were largely spared thanks to cyclical factors and high vaccination rates. But weather and… Read More »
The New York Times reports: From the start of the pandemic, the coronavirus seemed to target people carrying extra pounds. Patients who were overweight or obese were more likely to develop severe Covid-19 and more likely to die. Though these patients often have health conditions like diabetes that compound their risk, scientists have become increasingly… Read More »
