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.

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.

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.
- Tech
The first artificial material that follows sunlight may upgrade solar panels
Rows of tiny stemlike rods called SunBOTs orient themselves toward light, optimizing the solar energy that they can harvest.
- Chemistry
Molecular jiggling may explain why some solids shrink when heated
Scientists may have figured out how scandium fluoride crystals shrink as temperature rises, possibly leading to new insights into superconductors.
- Physics
Physicists have found quasiparticles that mimic hypothetical dark matter axions
These subatomic particles could make up dark matter in the cosmos. A mathematically similar phenomenon occurs in a solid material.
