Unexpected rates of warming threaten to change Antarctica and pose a threat to the survival of some of its penguins.

Tropical glaciers are vanishing at an especially rapid pace—and taking valuable climate records with them.

Bugs sing sweet nothings to each other.

Researchers are uncovering what makes a mug attractive.

Bacteria aren’t loners. In fact, they are quite social: These single-celled creatures band together to form sophisticated communities. They can even call out to each other to congregate, conspire and coordinate. Highly developed communication skills allow them to orchestrate small acts of cooperation and tackle big jobs as a unified force. For life’s tiniest players, living and working is a team sport. Researchers now want to join in the game — and change the rules. Synthetic biologists are working to find ways to manipulate entire microbe communities to get them to do thin... (p. 20)

Just expecting to feel better can sometimes cure what’s ailing you.

A collision between extraterrestrial objects and Earth’s ancient oceans could have produced raw materials for life.

Millions of stars are mysteriously racing toward one point in the sky.

Apparently, even fish want to break the rules sometimes. After spending weeks and months swimming in the open sea, mature Atlantic bluefin tuna return to the area where they first hatched. They do so in order to spawn, or reproduce. These bluefin tuna are divided into two groups: western Atlantic bluefins and eastern Atlantic bluefins. When it’s time to mate, the mature westerners head toward the Gulf of Mexico, while the mature easterners return to the Mediterranean. But a new study shows that when bluefins are young, they don’t always stick to their side of the ocean. Scientists foun...

Just before a planned repair mission, the space telescope goes quiet.
