It began in the 1980s with the heart-rate monitor. For the first time, an individual could observe changes in a vital sign as they happened. And they could do it on their own, whenever or wherever they chose, for any reason that made sense to them. Four decades later, we have rings, watches, scales, and …
Oceans hit their warmest levels on record for the fourth consecutive year in 2022, according to a new report by two dozen scientists.

The fossilization process is an unrelenting slog of decay, compression and erosion that can take millions of years and favors the preservation of tough material such as bones, teeth and shells. But with a little bit of sticky tree resin and a lot of luck, delicate bits of plants and tiny critters can sometimes last …

Science has long known that people living in what is now Siberia once walked (and later paddled boats) across the Being Strait into North America.

Scientist Leona Zacharias was a rare woman. She graduated from Barnard College in 1927 with a bachelor’s degree in biology, followed by a Ph.D. from Columbia University. But throughout her career, she labored behind men with loftier titles who got the bulk of the credit. In the 1940s, when premature newborns were going blind after being …
With dozens of large telescopes scattered across Earth and some well above it, you might think we’ve pretty much discovered all there is to find in the sky. But this is, literally, too narrow a view. The recent discovery of a huge cloud of gas floating near the Andromeda galaxy—one of the most extensively studied …

The animal world is full of delightfully odd genitals, from argonauts that detach their own sperm-bearing arm and send it off to find a female to mate with, to echidna males with four tipped penises. Some insects have even weaponized their genitals to fight predators. In another stand-out arrangement, male and female cave-dwelling barklice Neotrogla …
