Scientists Say: Hibernation
Hibernation is more than a deep sleep. Animals that hibernate lower their body temperature and reduce their body activities for months.
- Ecosystems
Underwater meadows appear to fight ocean germs
The seagrasses that sway in coastal currents are more than aquatic groundcover. They can reduce harmful bacteria that might otherwise sicken neighboring animals, new data show.

Sea ice around Antarctica shrinks to record low
Just two years after reaching a record high, the Antarctic sea ice extent has reached a new low.

How to chill an object by sending its heat into space
Researchers have designed a device that can cool an object by radiating its energy into outer space. Think of it as a solar panel in reverse.

Under blanket of ice, lakes teem with life
Life under frozen lakes is vibrant, complex and surprisingly active, new research finds. In fact, some plants and animals can only live under the ice. But with climate change, will that continue?

Warm petals may attract chilly bees
Dark-purple violet petals are warmer than a light-purple variant. And and that warmth might explain their attraction to potentially chilly bees.

Scientists Say: Hyperthermia
If our body temperatures rise too high, we can suffer from hyperthermia.
- Chemistry
Scientists claim to have turned hydrogen into a metal
Most people know hydrogen as a gas. But under high pressure, scientists now think they’ve converted it into a reflective metal. Not everyone is convinced.
