Physicists have coaxed ultracold atoms into an elusive form of quantum matter

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…

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…

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…

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…

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…

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 ……

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…

Fast radio bursts could help solve the mystery of the universe’s expansion

Astronomers have been arguing about the rate of the universe’s expansion for nearly a century. A new independent method to measure that rate could help cast the deciding vote. For…

Physicists’ devotion to symmetry has led them astray before

Second of two parts Physicists have a lot in common with Ponce de León and U2’s Bono. After decades of searching, they aren’t getting any younger. And they still haven’t…
