Scientists discover the secret behind the shrew’s amazing ability to shrink their brains 🧠

The clever trick sheds unwanted weight without compromising too much on cognition.

Rare seasonal brain shrinkage in shrews is driven by water loss, not cell death
Common shrews are one of only a handful of mammals known to flexibly shrink and regrow their brains. This rare seasonal cycle, known as Dehnel’s phenomenon, has puzzled scientists for decades. A study...

Fascinating symposium on using AI to observe animal behavior! AI has the potential to accelerate progress in wild animal welfare science, too, as tools become available that can recognize and track behavior, vocalizations, physiological markers, and body condition.
