At every moment, subatomic particles stream in unfathomable numbers through your body. Each second, about 100 billion neutrinos from the sun pass through your thumbnail, and you’re bathed in a…

Physicists dream big with an idea for a particle collider on the moon
If you could peer into a particle physicist’s daydream, you might spy a vision of a giant lunar particle accelerator. Now, researchers have calculated what such an enormous, hypothetical machine…
In a first, neutrinos were caught interacting at the Large Hadron Collider
The Large Hadron Collider’s claim to fame is its ability to unveil elusive subatomic particles. But there’s one class of particle that it had never directly detected, even though it…
Quantum physics requires imaginary numbers to explain reality
Imaginary numbers might seem like unicorns and goblins — interesting but irrelevant to reality. But for describing matter at its roots, imaginary numbers turn out to be essential. They seem…
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…
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…
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 ……
