Bloodthirsty vampire bats like to drink with friends over strangers
Cooperation among vampire bats extends beyond the roost. New research suggests that bonded bats often drink blood from animals together.
- Agriculture
Potty-trained cattle could help reduce pollution
About a dozen calves have been trained to pee in a stall. Toilet training cows on a large scale could cut down on pollution, researchers say.
- Earth
How AI can help forecast how much Arctic sea ice will shrink
Trained on sea ice observations and climate simulations, IceNet is 95 percent accurate in forecasting sea ice extent two months in advance.
- Animals
A giant tortoise was caught stalking, killing and eating a baby bird
Video captures the first documented instance of a tortoise hunting another animal.

What science tells us about reducing coronavirus spread from wind instruments
Performers struggled to find evidence that would free them from musical lockdown, so they partnered with researchers to get some answers.
- Animals
Squirrels use parkour tricks when leaping from branch to branch
Squirrels navigate through trees by making rapid calculations to balance trade-offs between branch flexibility and the distance between tree limbs.
- Space
How do scientists calculate the age of a star?
There are a few different methods to determine the age of a star, but none are perfect.
- Health & Medicine
The coronavirus cuts cells’ hairlike cilia, which may help it invade the lungs
Images show that the coronavirus clears the respiratory tract of hairlike structures called cilia, which keep foreign objects out of the lungs.
- Life
Pikas survive winter using a slower metabolism and, at times, yak poop
Pikas endure bone-chilling temperatures on the Qinghai-Tibetan Plateau by reducing their metabolism, and when possible, eating yak poop.
- Physics
Gravitational waves reveal the first known mergers of a black hole and neutron star
For the first time, LIGO and Virgo have detected long-anticipated gravitational waves from a black hole merging with a neutron star.
- Space
Cosmic filaments may be the biggest spinning objects in space
Filaments of dark matter and galaxies, which can stretch millions of light-years, might help astronomers figure out the origins of cosmic spin.
