NPR's Ari Shapiro talks with Regina Barber and Aaron Scott of NPR's Short Wave about Antarctica's melting ice, the weird anatomy of sea stars, and how a sleepless night can ease depression in mice.

Scientists have previously identified mutations in four genes—DEC2, NPSR1, GRM1, and ADRB1—associated with this rare trait.In the recent study, researchers analyzed the DNA of volunteers who ...

In the experiment, some of the mice were allowed to rest during the memory consolidation phase between training and memory retrieval. But others were manually monitored by people to make sure they ...

Mice not showing obvious signs of sleep deprivation doesn't necessarily mean that humans wouldn't show significant signs. Sleep is part of memory-forming, brain waste removal, ...

Pedro Schestatsky warns that not getting enough sleep favors the “accumulation of toxins such as beta-amyloid, which is ...

The study utilized 267 C57BL/6J mice, a strain commonly used in research, to assess sleep behaviors. Male mice averaged 670 minutes of sleep per 24-hour cycle – an hour longer than females. This ...

When they created mice with the same mutation, they found that the animals spent less time sleeping and, in behavioral tests, lacked the memory problems that typically follow a short night’s sleep.
