As ‘phantom rivers’ roar, birds and bats change their hunting habits
A massive experiment in the Idaho wilderness shows it’s not just human-made noises that impact ecosystems. Natural noises can too.

Mouse sperm thrived despite six years of exposure to space radiation
A space station experiment suggests future deep-space explorers don’t need to worry about passing the effects of space radiation on to their children.

The mere sight of illness may kick-start a canary’s immune system
Healthy canaries ramp up their immune systems when exposed to visibly sick birds, without actually being infected themselves.

Newly recognized tricks help elephants suck up huge amounts of water
New ultrasound imaging reveals what goes on inside a pachyderm’s trunk while feeding. It can snort water at the rate of 24 shower heads.

The teeth of ‘wandering meatloaf’ contain a rare mineral found only in rocks
The hard, magnetic teeth of the world’s largest chiton contain nanoparticles of santabarbaraite, a mineral never seen before in biology.

Gray wolves scare deer from roads, reducing dangerous collisions
The predators use roads as travel corridors, creating “a landscape of fear” that keeps deer away and saves millions of dollars a year, a study finds.

Mammal brains may use the same circuits to control tongues and limbs
When mice drink water, they make corrective motions with their tongues that resemble similar adjustments made by primates when they grab for objects.
