Droplets of these simple molecules may have helped kick-start life on Earth
Simple molecules called alpha hydroxy acids form cell-sized structures in conditions mimicking early Earth chemistry.

Boosting a gut bacterium helps mice fight an ALS-like disease
Gut bacteria may alter ALS symptoms for good or ill.

Manipulating nerve cells makes mice ‘see’ something that’s not there
Using optogenetics to stimulate about 20 nerve cells causes mice to perceive nonexistent vertical or horizontal lines.
- Paleontology
A flexible bone that helps mammals chew dates back to the Jurassic Period
A flexible bone that helps with chewing may have helped give rise to the Age of Mammals, a new fossil shows.

A deadly fungus gives ‘zombie’ ants a case of lockjaw
Clues left on infected ant jaws may reveal how the ‘zombie-ant-fungus’ contracts ant muscles to make their death grip.
- Ecosystems
Planting trees could buy more time to fight climate change than thought
Earth has nearly a billion hectares suitable for new forests to start trapping carbon, a study finds.
- Genetics
This gene may help worms live longer, but not healthier
Antiaging therapies may have trade-offs, research on worms suggests.

Spraying bats with ‘good’ bacteria may combat deadly white nose syndrome
Nearly half of bats infected with white nose syndrome survived through winter after being spritzed with antifungal bacteria, a small study finds.

Tiny glasses help reveal how praying mantises can see in 3-D
Newfound nerve cells in praying mantises help detect different views that each of the insects’ eyes sees, a mismatch that creates depth perception.
- Paleontology
An ancient bird found encased in amber had a bizarrely long toe
A 99-million-year-old fossil holds a bird with an oddly long toe, which might have helped the critter hook hard-to-reach dinners.
- Animals
Southern right whale moms and calves may whisper to evade orcas
Mother-calf whale pairs call to each other quietly to stay in touch while avoiding attracting the attention of predators, a study suggests.
- Neuroscience
Both fish and humans have REM-like sleep
Sleeping zebrafish have brain and body activity similar to snoozing mammals, suggesting that sleep evolved at least 450 million years ago.
