Scientists uncover hidden superconductivity in material once thought only magnetic

A new study shows that iron telluride, or FeTe, long thought to be a simple magnetic metal, is actually a superconductor when excess iron atoms are removed. Superconductors carry electricity with no energy loss as heat, enabling technologies such as MRI machines, particle accelerators and potentially quantum computers. Researchers found that extra iron atoms hidden […]

St. Olaf researchers built a computer that doesn’t require electricity

Researchers from St. Olaf College and Syracuse University have built mechanical computers made entirely of common materials that can perform simple calculations without electricity or batteries. Led by St. Olaf College physics professor Joey Paulsen, the team used steel springs and bars to create devices that store and process information by physically responding to motion […]

Graphene just defied a fundamental law of physics

Scientists have observed electrons in graphene flowing like a nearly frictionless liquid, revealing an unusual quantum state that challenges long-standing assumptions in physics and could enable future technologies. Physicists have long sought evidence that electrons can behave collectively as a smooth fluid governed by universal quantum properties, but such behavior is difficult to detect because […]
