In PTSD, a good night’s sleep means feeling safe
Studies of PTSD in rats have usually focused on fear and trauma. But a new study in humans shows that learning about safety may be important as well.

Our brains sort words as we sleep
Even after nodding off, a person’s brain correctly sorts words into categories, adding to the achievements of the sleeping brain.

Hummingbirds evolved a strange taste for sugar
While other birds seem to lack the ability to taste sugar, hummingbirds detect sweetness using a repurposed sensor that normally responds to savory flavors.

Dolphins and whales may squeal with pleasure too
Dolphins and whales squeal after a food reward in about the same time it takes for dopamine to be released in the brain.
