David Leonhardt writes: For the 15 million Americans who have received the Johnson & Johnson Covid vaccine, the confusing messages from the federal government just keep coming. An F.D.A. advisory panel is scheduled to vote today on whether J. & J. recipients should receive a booster shot. But the panel is not likely to vote… Read More »

Nature reports: Infectious-diseases physician Krutika Kuppalli had been in her new job for barely a week in September 2020, when someone phoned her at home and threatened to kill her. Kuppalli, who had just moved from California to the Medical University of South Carolina in Charleston, had been dealing with online abuse for months after… Read More »
Johnjoe McFadden writes: It’s May 1964 and, on a low hillside in New Jersey, the physicists Robert Woodrow Wilson and Arno Allan Penzias are listening in on the Universe. They are standing beneath what looks like a gargantuan ear trumpet attached to a garden shed: the Holmdel Horn Antenna, built by Bell Laboratories to investigate… Read More »
Carolyn Kormann writes: Since the coronavirus first appeared, at the end of 2019, four and a half million people have died, countless more have suffered, whole economies have been upended, schools have been shuttered. Why? Did the virus jump from an animal to its first human host, its patient zero? Or, as some suspect, was… Read More »
Scientific American reports: The people who happen to be in a city center at any given moment may seem like a random collection of individuals. But new research featuring a simple mathematical law shows that urban travel patterns worldwide are, in fact, remarkably predictable regardless of location—an insight that could enhance models of disease spread… Read More »
The New York Times reports: The world has gained a new weapon in the war on malaria, among the oldest known and deadliest of infectious diseases: the first vaccine shown to help prevent the disease. By one estimate, it will save tens of thousands of children each year. Malaria kills about half a million people… Read More »
Cathleen O’Grady writes: Color is a spectrum: Red fades from orange to yellow, whereas green merges to turquoise, then blue. Languages treat this spectrum in different ways: Some have separate words for “green” and “blue,” others lump the two together. Some barely bother with color terms at all. “The question is, why?” says Dan Dediu,… Read More »
Rivka Galchen writes: Let’s say that you’ve devoted your entire adult life to developing a carbon-free way to power a household for a year on the fuel of a single glass of water, and that you’ve had moments, even years, when you were pretty sure you would succeed. Let’s say also that you’re not crazy.… Read More »
Daniel Everett writes: The roll of scientists born in the 19th century is as impressive as any century in history. Names such as Albert Einstein, Nikola Tesla, George Washington Carver, Alfred North Whitehead, Louis Agassiz, Benjamin Peirce, Leo Szilard, Edwin Hubble, Katharine Blodgett, Thomas Edison, Gerty Cori, Maria Mitchell, Annie Jump Cannon and Norbert Wiener… Read More »
Daniel Engber and Adam Federman write: As the pandemic drags on into a bleak and indeterminate future, so does the question of its origins. The consensus view from 2020, that SARS-CoV-2 emerged naturally, through a jump from bats to humans (maybe with another animal between), persists unchanged. But suspicions that the outbreak started from a… Read More »
Nature reports: Six months ago, Miles Davenport and his colleagues made a bold prediction. On the basis of published results from vaccine trials and other data sources, they estimated that people immunized against COVID-19 would lose approximately half of their defensive antibodies every 108 days or so. As a result, vaccines that initially offered, say,… Read More »
The Scientist reports: While researchers have found plenty of gene variants that seem to increase the risk of an autism diagnosis, it’s not clear why some people carrying these mutations develop autism spectrum disorders and some do not. In a study published today (September 17) in Science Advances, researchers point to a potential answer: severe… Read More »
Robin George Andrews writes: Réunion, a French island in the western Indian Ocean, is like a marshmallow hovering above the business end of a blowtorch. It sits above one of Earth’s mantle plumes — a tower of superheated rock that ascends from the deep mantle and flambés the bases of tectonic plates, the jigsaw pieces… Read More »
The Guardian reports: Healthy boys may be more likely to be admitted to hospital with a rare side-effect of the Pfizer/BioNTech Covid vaccine that causes inflammation of the heart than with Covid itself, US researchers claim. Their analysis of medical data suggests that boys aged 12 to 15, with no underlying medical conditions, are four… Read More »
