An elusive form of matter called a quantum spin liquid isn’t a liquid, and it doesn’t spin — but it sure is quantum. Predicted nearly 50 years ago, quantum spin…

Scientists finally detected a quantum effect that blocks atoms from scattering light
A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No…
One of nature’s key constants is much larger in a quantum material
A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called…
Scientists are one step closer to error-correcting quantum computers
Mistakes happen — especially in quantum computers. The fragile quantum bits, or qubits, that make up the machines are notoriously error-prone, but now scientists have shown that they can fix…
How lizards keep detachable tails from falling off
Lizards are famous for losing their tails, but perhaps the bigger question should be: How do their tails stay on? The answer may lie in the appendage’s internal design. A…
Materials of the last century shaped modern life, but at a price
A 1920s science headline, “Ice cream from crude oil,” may best capture the era’s unbridled enthusiasm for chemistry. “Edible fats, the same as those in vegetable and animal foods ……
A diamondlike structure gives some starfish skeletons their strength
Some starfish made of a brittle material fortify themselves with architectural antics. Beneath a starfish’s skin lies a skeleton made of pebbly growths, called ossicles, which mostly consist of the…
This eco-friendly glitter gets its color from plants, not plastic
All that glitters is not green. Glitter and shimmery pigments are often made using toxic compounds or pollutive microplastics (SN: 4/15/19). That makes the sparkly stuff, notoriously difficult to clean…
The thickness of lead’s neutron ‘skin’ has been precisely measured
Some atomic nuclei are thin-skinned — they’re surrounded by a slim shell of neutrons. Physicists now know how thick that neutron skin is for one particular type of nucleus. The…
The already tiny neutrino’s maximum possible mass has shrunk even further
To understand neutrinos, it pays to be small-minded. The subatomic particles are so lightweight, they’re almost massless. They’re a tiny fraction of the mass of the next lightest particle, the…
