New clues emerge in 30-year-old superconductor mystery

One of the greatest mysteries of experimental physics is how so-called high-temperature superconducting materials work. Despite their name, high-temperature superconductors—materials that carry electrical current with no ...

Researchers demonstrate new type of laser

Lasers are everywhere nowadays: Doctors use them to correct eyesight, cashiers to scan your groceries, and quantum scientist to control qubits in the future quantum computer. For most applications, the current bulky, energy-inefficient ...

Steps toward room-temperature superconductivity

The possibility of achieving room temperature superconductivity took a tiny step forward with a recent discovery by a team of Penn State physicists and materials scientists.

Scientists model Mars climate to understand habitability

A Southwest Research Institute scientist modeled the atmosphere of Mars to help determine that salty pockets of water present on the Red Planet are likely not habitable by life as we know it on Earth. A team that also included ...

Observing electrons surfing waves of light on graphene

Researchers have studied how light can be used to observe the quantum nature of an electronic material. They captured light in graphene and slowed it down to the speed of the material's electrons. Then electrons and light ...

Pair claim they have turned hydrogen to metal

(PhysOrg.com) -- Many have tried, but none have succeeded. For at least a hundred years, scientists looking at hydrogen have scratched their chins when musing over the fact that it, as an alkali metal, by all rights should ...

Cracking the mystery of perfect superconductor efficiency

In 1911, physicist Heike Kamerlingh Onnes aimed to lower mercury's temperature to as close to absolute zero as possible. He hoped to win a disagreement with Lord Kelvin, who thought metals would stop conducting electricity ...

Clusters of gold atoms form peculiar pyramidal shape

Freestanding clusters of 20 gold atoms take the shape of a pyramid, researchers have discovered. This is in contrast with most elements, which organize themselves by forming shells around one central atom. The team of researchers ...
