Is it possible for the brain to stop producing dreams? And could something be wrong in the brains of people who report never dr ...read more

Say you’re out walking late at night, and you come across a pair of glowing dots in the distance. Maybe they’ll blink at you, or they’ll just watch quietly. Don’t get too spooked – that’s just an animal looking back at you.It may certainly feel creepy but rest assured that there are no ghostly forces behind those uncanny lights. The reason behind this phenomenon is much simpler: It’s the result of evolutionary mechanisms which allow certain species to see better in the dark.Why Do ...read more

For centuries, a beached whale provided coastal dwellers with a windfall of resources. People harvested the baleen, blubber, bone, meat, oil, and spermaceti. They used oil and spermaceti to fuel candles and lanterns. They consumed whale meat. And they repurposed bone and baleen (a plate in the upper jaw) to structure corsets, collars, and hoop skirts. Around 1710, people wanted a steady supply of whale-based products. The commercial whaling industry developed in response to the increasing dem ...read more

In 2020, researchers caught something strange — and stunningly cute — on camera. In the dead of night in the southern Santa Cruz Mountains, a coyote and a badger sauntered out of a wildlife tunnel. The two ambled around then turned around, bumbling back toward the tunnel, but not before showing off the strength of their bond. As the coyote waited for the badger, it bowed its body and wagged its tail, almost as if it was inviting the badger to play. Seeing a coyote and a badger together in th ...read more
