Insects flocking to artificial lights may not know which way is up
Insects may use light to figure out where the ground is. Artificial lights send them veering off course, data from high-speed infrared cameras suggests.

Geneticist Krystal Tsosie advocates for Indigenous data sovereignty
A member of the Navajo Nation, she believes Indigenous geneticists have a big role to play in protecting and studying their own data.

Under very rare conditions, Alzheimer’s disease may be transmitted
Alzheimer’s isn’t contagious. But contaminated growth hormone injections caused early-onset Alzheimer’s in some recipients, a new study suggests.
- Animals
What parrots can teach us about human intelligence
By studying the brains and behaviors of parrots, scientists hope to learn more about how humanlike intelligence evolves.
- Neuroscience
Handwriting may boost brain connections more than typing does
Students asked to write words showed greater connectivity across the brain than when they typed them, suggesting writing may be a better boost for memory.
- Ecosystems
How an invasive ant changed a lion’s dinner menu
An invasive ant is killing off ants that defend trees from elephants. With less cover, it’s harder for lions to hunt zebras, so they hunt buffalo instead.
- Animals
A bird flu outbreak is sweeping the globe. Its long-term effects are unclear
A reporter’s recent trip to the Galápagos offered a chance to reflect on the bird flu outbreak, which has killed millions of birds and other animals.

Some honeybees in Italy regularly steal pollen off the backs of bumblebees
New observations suggest that honeybees stealing pollen from bumblebees may be a crime of opportunity, though documentation of it remains rare.
- Plants
This first-of-its-kind palm plant flowers and fruits entirely underground
Though rare, plants across 33 families are known for subterranean flowering or fruiting. This is the first example in a palm.

These snails give live birth, and it’s the babies that may do the labor
Protecting eggs in mom’s body may have given rough periwinkle snails an advantage over egg-laying cousins, letting them spread to far more coastline.

Megalodon, the largest shark ever, may have been a long, slender giant
The ancient shark is typically imagined with the scaled-up stout frame of a modern great white. But in life, the giant may have been more elongated.

How disease-causing microbes load their tiny syringes to prep an attack
Tracking individual proteins in bacterial cells reveals a shuttle-bus system to load tiny syringes that inject our cells with havoc-wreaking proteins.
