The first room-temperature superconductor has finally been found
A compound of carbon, hydrogen and sulfur conducts electricity without resistance up to 15° C, but there’s a catch: It works only under high pressure.
- Physics
Fundamental constants place a new speed limit on sound
Physicists propose a new maximum rate that sound waves can travel under conditions normally found on Earth — 36 kilometers per second.
- Physics
A new device can produce electricity using shadows
Even under low light, this new technology exploits the contrast between light and shade to produce a current that can power small electronics.
- Physics
50 years ago, superconductors started feeling the pressure
Today, high-pressure superconductors are a hot topic. 50 years ago, scientists were just starting to explore the possibilities.
- Physics
A newfound superconducting current travels only along a material’s edge
In a first, scientists spot electricity flowing without resistance on the rim of a topological superconductor.

To cook a perfect steak, use math
As a steak cooks in an oven, movement of liquid within the meat causes it to become extra juicy in the center in a way that can be predicted by mathematics.

How materials science has changed humankind — for better and worse
As people began wielding new materials, the technologies fundamentally changed humankind, the new book ‘The Alchemy of Us’ argues.
- Physics
A mysterious superconductor’s wave could reveal the physics behind the materials
Scientists finally spotted a pair-density wave in a high-temperature superconductor.

Legos may take hundreds of years to break down in the ocean
Sturdy types of plastic may persist in seawater for much long than scientists previously thought.

The containers the U.S. plans to use for nuclear waste storage may corrode
The different components of a nuclear waste storage unit start to corrode each other when wet, new lab experiments show.
- Materials Science
This material could camouflage objects from infrared cameras
A coating of samarium nickel oxide counteracts hotter objects’ tendency for brighter thermal radiation.

Lead becomes stronger than steel under extreme pressures
Lead is a soft metal, easily scratched with a fingernail. But that changes dramatically when the metal is compressed under high pressures.
