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.

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.

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.

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.

A new cooling technique relies on untwisting coiled fibers
A “twist fridge” operates via twistocaloric cooling, a technique that generates cooling by unraveling twisted strands.

Andrea Young uncovers the strange physics of 2-D materials
Physicist Andrea Young has set his sights on the strange ways electrons behave in flat, layered structures.
- Physics
A new magnetic swirl, or skyrmion, could upgrade data storage
Magnetic whorls in a new type of material could be easier to control than their predecessors.

A predicted superconductor might work at a record-breaking 200° Celsius
A material made of hydrogen, lithium and magnesium and squeezed to high pressures may be a superconductor even at especially high temperatures.
- Tech
A chip made with carbon nanotubes, not silicon, marks a computing milestone
Silicon’s reign in cutting-edge electronics may soon over. The carbon nanotube could be its successor.
- Chemistry
Plant-based fire retardants may offer a less toxic way to tame flames
Flame retardants created from plant materials could be less harmful to the environment than traditional flame-smothering chemicals.
