This story originally appeared in Hakai and is part of the Climate Desk collaboration. Arah Narida leans over a microscope to gaze into a plastic petri dish containing a hood coral. The animal—a pebbled blue-white disk roughly half the size of a pencil eraser—is a marvel. Just three weeks ago, …

Boom and bust don’t hit much harder than in the Bering Sea. After reaching historically high numbers, the population of snow crabs there cratered by 90 percent following a heat wave in 2018 and 2019. Some 10 billion disappeared. Water temperatures had risen 3 degrees Celsius, but that probably didn’t …

Feline researchers have long believed that purring is produced by voluntary muscle contractions, but a new report indicates that this vibration in the larynx of cats may be explained by the myoelastic aerodynamic theory of phonation. Studies on the complex action that produces a unique vibration in the larynx of …

Thanks to some genetic tricks, plants can now speak in color. A team of researchers at the University of California, Riverside hacked the natural stress response system in Arabidopsis thaliana, a small white-flowered plant from the mustard family that serves as a common model organism in plant biology labs. When …

Clinical depression is considered one of the most treatable mood disorders, but neither the condition nor the drugs used against it are fully understood. First-line SSRI treatments (selective serotonin reuptake inhibitors) likely free up more of the neurotransmitter serotonin to improve communication between neurons. But the question of how SSRIs …

Two companies have launched clinical trials to see if they can restore hearing to children with a rare type of genetic deafness. Akouos and Decibel Therapeutics, both based in Boston, are testing experimental therapies in children with severe hearing loss due to variations in a gene called OTOF. A third …

Salmon are legendary for their commitment to procreation. You know the drill: They wander the ocean before returning to rivers where they hatched, fire themselves upstream to spawn, and then drop dead. It’s not such a rigid life cycle, though. In fact, it’s a system that’s allowed a species like …

There’s much, much more to the rainforest than meets the eye. Even a highly trained observer can struggle to pick out individual animals in the tangle of plant life—animals that are often specifically adapted to hide from their enemies. Listen to the music of the forest, though, and you can …

This month, the Cambodian government reported that two people there died of highly pathogenic avian influenza, or H5N1 bird flu, after being exposed to infected poultry. For people, the risk of getting infected is low, but outbreaks in animals have been rising worldwide, wiping out chicken flocks and wild bird …

The original version of this story appeared in Quanta Magazine. In 1848, when Louis Pasteur was a young chemist still years away from discovering how to sterilize milk, he discovered something peculiar about crystals that accidentally formed when an industrial chemist boiled wine for too long. Half of the crystals …
