Realigning magnetic fields may drive the sun’s spiky plasma tendrils
Solar spicules emerge near counterpointing magnetic fields, hinting that self-adjusting magnetism creates these filaments, which may heat the corona.
- Animals
Flipping a molecular switch can turn warrior ants into foragers
Toggling one protein soon after hatching makes Florida carpenter ants turn from fighting to hunting for food.

Silver-backed chevrotains have been ‘rediscovered’ by science after 29 years
With help from Vietnamese villagers, researchers captured photos of a species of deerlike ungulate thought lost to science nearly three decades ago.
- Neuroscience
Sleep may trigger rhythmic power washing in the brain
Strong, rhythmic waves of cerebrospinal fluid wash into the human brain during sleep and may help clean out harmful proteins.
- Life
Vampire bat friendships endure from captivity to the wild
Vampire bats can form social bonds that persist from a lab setting to the outdoors, suggesting the cooperative relationships are like friendships.
- Life
Saharan silver ants are the world’s fastest despite relatively short legs
Saharan silver ants can hit speeds of 108 times their body length per second.
- Space
The solar system may have a new smallest dwarf planet: Hygiea
