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.
- Animals
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.

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.

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
New images reveal Hygiea is round, a final criterion for promoting the wee world from asteroid to dwarf planet status.
- Animals
Humpback whales use their flippers and bubble ‘nets’ to catch fish
A study reveals new details of how humpback whales hunt using their flippers and a whirl of bubbles to capture fish.
- Space
A supermassive black hole shredded a star and was caught in the act
Astronomers have gotten the earliest glimpse yet of a black hole ripping up a star, a process known as a tidal disruption event.
- Climate
