Why breakthrough solar cells often fail to reach your roof
Many new energy technologies look impressive in the laboratory but never become real products.
Solar cells are a clear example. Scientists can achieve record performance...
Scientists discover how to block noise without blocking airflow
Designing spaces that are both well ventilated and quiet has always been difficult.
Openings that allow fresh air to circulate—such as vents and ducts—also let...
MIT’s new AI turns creative 3D designs into objects that won’t break
Generative artificial intelligence can produce amazing designs for objects such as decorations, furniture, and accessories.

Scientists develop electrified charcoal sponge to capture CO₂ from air
Researchers have created a new, low-cost, and energy-efficient method for capturing carbon dioxide (CO₂) directly from the air using an electrified charcoal "sponge."
This breakthrough...
White dwarfs pause their cooling, giving planets a second chance for habitability
When we first began searching for planets around other stars, one of the surprising discoveries was that there are planets orbiting white dwarfs.
The first...
Scientists say a nearby supernova could solve the mystery of dark matter
For nearly 90 years, scientists have been searching for answers about dark matter—the invisible substance that makes up 85% of the universe’s matter.
Now, researchers...
