Why some birds of paradise have ultrablack feathers
Birds of paradise have superblack feathers because of tilted, spiky microscopic features in their feathers.
- Neuroscience
Scientists are seeking new strategies to fight multiple sclerosis
Facing so many unknowns about multiple sclerosis, researchers explore the immune system, the neurons and the gut to fight the disease.
- Planetary Science
See a new mosaic of images of comet 67P from the Rosetta mission
A montage of images taken by the Rosetta spacecraft and its lander, Philae, recap the daring mission to comet 67P.
- Earth
How hurricanes and other devastating disasters spur scientific research
Hurricanes such as Harvey, Irma and others have been devastating, even deadly, yet they drive our desire for scientific discovery.
- Planetary Science
Moons of Uranus face future collision
By studying variations in the rings of Uranus, researchers have determined the mass and density of the planet’s moon Cressida.

- Physics
Scientists create the most cubic form of ice crystals yet
Ice has taken on a strange structure, with its water molecules arranged in nearly perfect cubes.
- Planetary Science
Mars has nighttime snow storms
When clouds of water-ice particles cool at night, snow starts to fall rapidly on Mars, simulations suggest. The squalls could explain observations made by the Phoenix lander in 2008.
- Planetary Science
Moon had a magnetic field for at least a billion years longer than thought
The moon’s magnetic field could have lasted until about a billion years ago.
- Animals
Fossil find suggests this ancient reptile lurked on land, not in the water
An exquisitely preserved fossil shows that an ancient armored reptile called Eusaurosphargis dalsassoi wasn’t aquatic, as scientists had suspected.
- Climate
South Asia could face deadly heat and humidity by the end of this century
If climate change is left unchecked, simulations show extreme heat waves in densely populated agricultural regions of India and Pakistan.
