The diabolical ironclad beetle can survive getting run over by a car. Here’s how
The diabolical ironclad beetle is an incredibly tough little creature. A peek inside its exoskeleton reveals what makes it virtually uncrushable.
- Physics
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.

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.
