Spend an hour wandering along a river and you may wonder why the water rushing by chose this particular path over any other. While many nature writers might offer philosophical musings on the subject, Where the River Flows author Sean Fleming has physics on his side. Physics isn’t the lens through which most people think […]
Arctic sea ice has hit a record low for the third year in a row. It’s the paltriest maximum extent seen since recordkeeping began in 1979, scientists at NASA and the National Snow and Ice Data Center announced March 22. Total sea ice cover on the Arctic Ocean peaked on March 7, satellite observations show, […]
A hefty red, dead galaxy in the early universe appears to have bulked up a bit too fast. The galaxy, seen as it was when the universe was only 1.65 billion years old, weighs at least three times as much as the Milky Way, but has stopped making stars. Other galaxies at the time tend […]
Your lukewarm cup of coffee won’t suddenly heat itself up, no matter how long you put off the trek to the microwave. But the same rule doesn’t necessarily apply to quantum systems. Like chilly air warming a mug, heat can spontaneously flow from a cold quantum particle to a hotter one under certain conditions, researchers […]
CHICAGO — A once-daily capsule safely suppressed reproductive hormones in men, making it an appealing candidate for a male birth control pill, according to a small study. After about a month of treatment, a new prototype pill called dimethandrolone undecanoate, or DMAU, had reduced levels of hormones including testosterone that are necessary for sperm production. […]
Cocooned within the bowels of the Earth, one mineral’s metamorphosis into another may trigger some of the deepest earthquakes ever detected. These cryptic tremors — known as deep-focus earthquakes — are a seismic conundrum. They violently rupture at depths greater than 300 kilometers, where intense temperatures and pressures are thought to force rocks to flow […]
Potential hints of weird new particles in a dark matter detector have evaporated with new data. Following up on a beguiling result from its predecessor experiment, the XENONnT experiment found no sign of extra blips that could point to new particles or another phenomenon, scientists report July 22 in Vienna at the International Conference on […]
It may soon be too late to end the global monkeypox epidemic. “We are losing the window to be able to contain this outbreak,” Boghuma Titanji, an infectious diseases doctor and virologist at Emory University in Atlanta said July 21 during a seminar sponsored by the Harvard Kennedy School’s Belfer Center for Science and International […]
