How a tiny spider uses silk to lift prey 50 times its own weight
Dropping the right silk can haul mice, lizards and other giants up off the ground.

50 years ago, scientists made the case for a landlubbing Brontosaurus
In 1971, a scientist argued for a landbound Brontosaurus instead of a swampy swimmer. Recent evidence comes from studies of its ancient environment.

Lizard-like tuatara carry two distinct mitochondrial genomes
Having two mitochondrial genetic instruction books, a first for vertebrates, may help explain tuatara’s unique ability to tolerate cold temperatures.

Naked mole-rat colonies speak with unique dialects
Machine learning reveals that these social rodents communicate with distinctive speech patterns that are culturally inherited.

A new orange and black bat species is always ready for Halloween
A new species from the sky islands of Africa’s Nimba Mountains shows bats’ colorful streak.

Giant worms may have burrowed into the ancient seafloor to ambush prey
20-million-year-old tunnels unearthed in Taiwan may have been home to creatures that ambushed prey similar to today’s monstrous bobbit worms.

Some bacteria are suffocating sea stars, turning the animals to goo
For years, researchers thought an infectious pathogen was behind sea star wasting disease. Instead, bacteria deplete the starfishes’ oxygen.

Monitor lizards’ huge burrow systems can shelter hundreds of small animals
Two species of Australian monitor lizards dig nests four meters deep. Now scientists reveal that the burrows are home to far more than their creators.

Some electric eels coordinate attacks to zap their prey
Electric eels were thought be to solitary hunters, until researchers observed over 100 eels hunting together, releasing coordinated electric attacks on corralled prey.

Rats with poisonous hairdos live surprisingly sociable private lives
Deadly, swaggering rodents purr and snuggle when they’re with mates and young.

Newborn megalodon sharks were larger than most adult humans
Preserved pieces of backbone suggest that megalodon sharks were about 2 meters long at birth.
- Neuroscience
Mice may ‘catch’ each other’s pain — and pain relief
Healthy mice mirror a companion’s pain or morphine-induced relief. Disrupting certain connections in the brain turns off such empathetic behaviors.
