MIT’s smart pill confirms you took your medicine

MIT engineers have developed a pill that can wirelessly report when it’s been swallowed. Inside the capsule is a biodegradable antenna that sends a signal within minutes of ingestion, then safely dissolves. The system is designed to work with existing medications and could help

A shocking amount of plastic is floating in city air

Plastic pollution is not just in oceans and soil. Scientists have now found enormous amounts of microscopic plastic floating through urban air, far exceeding earlier estimates. Road dust and rainfall play a major role in moving these particles through the atmosphere. The

This common dinner rule makes meals more awkward

Waiting to eat when your food arrives first feels polite—but it may be mostly for your own peace of mind. Researchers found people feel far more uncomfortable breaking the “wait until everyone is served” rule than they expect others would feel watching it happen. Even being

Image: Artist's concept of a white dwarf star

A smaller white dwarf star (left) pulls material from a larger star into a swirling accretion disk in this artist's concept released Nov. 19, 2025, to illustrate the first use of NASA's IXPE (Imaging X-ray Polarization Explorer) to study a white dwarf star.

Gamma rays quickly toughen nitrogen‑fixing bacteria

Heat-resilient biofertilizers could help crops cope with rising temperatures but engineering them has been slow and uncertain. A new study at the National Institutes for Quantum Science and Technology (QST) shows that pairing experimental evolution with controlled gamma-ray

EPA opposes Colorado plan to close coal-fired power plants

On Jan. 9, The Environmental Protection Agency determined Colorado cannot order the closure of coal-fired power plants under the Clean Air Act, and, therefore, the agency will deny the state's plan to reduce the haze that clouds views at Rocky Mountain National Park and other

How marine viruses help fuel underwater oxygen-rich zones

Newly published interdisciplinary research led by the University of Tennessee, Knoxville, and University of Maryland shows that viral infection of blue-green algae in the ocean stimulates productivity in the ecosystem and contributes to a rich band of oxygen in the water.

Hubble spies stellar blast setting clouds ablaze

This new NASA Hubble Space Telescope image captures a jet of gas from a forming star shooting across the dark expanse. The bright pink and green patches running diagonally through the image are HH 80/81, a pair of Herbig-Haro (HH) objects previously observed by Hubble in 1995.
