Bottled water hosts many thousands of nano-sized plastic bits
The finding emerges from tests of a new tool that identified smaller-than-ever tiny plastic bits in three brands of bottled water.

The weird sky glow called STEVE is really confusing scientists
Researchers are trying to figure out the recipe of atmospheric conditions that creates this aurora-like light show.

Which way is up? Insects may lose track near artificial lights
Flying insects may use light to figure out where the sky is. But artificial lights can send them veering off course, high-speed video suggests.

A weird upside-down world lurks beneath Antarctica’s ice
A vast swath of ocean surrounds Antarctica, hidden under the ice. Here, strange creatures burrow into the dark underbelly of a floating glacier.

Swimming in schools lets fish save lots of energy
Each tail flap uses less than half as much energy than swimming solo, making it easier for fish to catch their breath after an underwater sprint.
- Artificial Intelligence
To ‘green’ AI, scientists are making it less resource-hungry
Energy demands of ChatGPT and similar AI tools can threaten Earth’s climate. So researchers have begun redesigning how to run data centers and build AI.
- Life
Scientists Say: Ichnology
This field of science looks to understand life — past and present — by studying how organisms altered their surroundings.
- Climate
Chemists make device to destroy planet-warming methane pollution
It can slash diffuse sources of this extremely potent greenhouse gas, such as from livestock barns and other sites.

Warmer seas trigger skyrocketing ice loss in 3 Antarctic glaciers
Destabilized by waves and vanishing sea ice, one of the glaciers lost 25 kilometers (15.5 miles) of ice in 16 months — a possible hint of worse to come.
- Physics
Scientists Say: Coriolis Effect
Because Earth spins, airborne objects traveling far and fast — such as airplanes — experience deflections in their motion.
