Mudskippers use watery tongue to slurp up snacks on land
When mudskippers move from water to land, they use a tongue made of water to move food to the back of their throat and into their stomachs.
- Animals
Evidence of ‘yeti’ probably came from a Himalayan black bear
Last year, a genetic analysis revealed two hairs from an unknown species of bear in Asia. A new study finds that they belong to rare Himalayan black bears.

Finches can pass H7N9 bird flu to chickens
In laboratory experiments, society finches spread H7N9 into water when they drank, infecting chickens and quail that drank the same water.
- Genetics
The upside of a demolished chromosome
A woman’s rare genetic disease was cured when a chromosome carrying the mutant gene shattered.
- Animals
Snail shell creates blue iridescence with mineral
Mollusk shines blue using calcium compound rather than organic molecule.
- Life
Cyborg beetles reveal secrets of insect flight
Remote controlled beetles swoop to the rescue in insect flight simulations.
- Paleontology
Rise of East African Plateau dated by whale fossil
A whale fossil is helping to pinpoint when the East African Plateau started to rise and how the uplift played a role in human evolution, scientists say.
- Animals
Getting stabbed is no fun for land snails
When hermaphroditic land snails mate, they stab each other with “love darts.” But being darted comes at a price, a new study finds.
- Animals
Nanocrystals explain chameleons’ color shifts
Tiny crystals embedded in chameleons’ skin reflect specific wavelengths of light based on their position, explaining how chameleons change colors.
- Animals
A brain chemical tells when to fight or flee
Crickets tally the knocks they take in a fight, and flee when their brains release nitric oxide to tell them they’ve had enough.
- Life
For healthy eating, timing matters
Limiting eating times improves heart function in fruit flies.
- Neuroscience
Sniffing out human pheromones
A new review argues that most of the chemicals labeled human pheromones, and the experiments behind them, don’t pass the smell test.
