The International Space Station lacks microbial diversity. Is it too clean?
Hundreds of surface swabs reveal the station lacks microbial diversity, an imbalance that has been linked to health issues in other settings.

Mount Vesuvius turned this ancient brain into glass. Here’s how
Transforming the brain tissue to glass would have required an extremely hot and fast-moving ash cloud, lab experiments suggest.
- Health & Medicine

Biological sex is not as simple as male or female
A recent Trump executive order defines sex based on gamete size. But the order oversimplifies genetics, hormones and reproductive biology.
- Paleontology
Giant camel-like creatures lived thousands of years longer than once thought
Fossilized teeth from two ancient megafauna suggest they roamed Brazil 3,500 years ago. The find “opens the door to rewrite South American history.”
- Animals
How a mushroom coral goes for a walk without legs
Time-lapse video shows how a mushroom coral polyp pulses and inflates, flinging its soft body into micro-hops to slowly move itself to a new location.
