Hidden magnetic waves discovered in high-temperature superconductors

Advanced x-ray technique reveals surprising quantum excitations that persist through materials with or without superconductivity.

A crystal of a different color: One chemical forms two colors of crystals, sheds insight on agostic bonds important in industrial catalysis

Chemists have unexpectedly made two differently colored crystals -- one orange, one blue -- from one chemical in the same flask while studying a special kind of molecular connection called an agostic bond. The discovery provides industrial chemical reactions such as those that occur while making plastics and fuels.

NASA's Hubble Finds Telltale Fireball After Gamma Ray Burst

NASA's Hubble Space Telescope recently provided the strongest evidence yet that short-duration gamma ray bursts are produced by the merger of two small, super-dense stellar objects.

Predicted experimental test will clarify how light interacts with matter at high energies

Collisions of atomic and subatomic particles at very high energies reveal important properties about the beginning of the Universe and the atomic forces, and how fundamental particles are formed and react with each other. Adam Bzdak from the RIKEN BNL Research Center and colleague Vladimir Skokov from Brookhaven National Laboratory in the US have now proposed a scheme that allows for a better understanding of how light and subatomic particles react with each other during such high-energy collisions.

Researchers find way to measure speed of spinning object using light's orbital angular momentum

(Phys.org) —Researchers in Scotland have devised a way to use the Doppler Effect to discern the spin speed of a rotating object where the object is directly facing the light source. In their paper published in the journal Science, the team describes lab experiments they conducted that allowed them to observe a frequency shift proportional to the product of the rotation frequency of an object and the orbital angular momentum of the light.

Cosmic Recipe for Earthlings

Crucial elements in people formed later in the universe's history than expected.

NASA Curiosity Rover Approaches First Anniversary on Mars

NASA's Curiosity rover will mark one year on Mars next week and has already achieved its main science goal of revealing ancient Mars could have supported life.

Calibrators from deep space tune high-tech earthbound physics experiments

Hold out your hand: Look closely. If you're outside on a sunny day, you might see dust motes and pollen dance in the air, perhaps landing on your skin, and bright rays of sunlight peek between your fingers. To the naked eye, your skin provides a barrier between your body and these exterior elements. The light refracts around your palm, not through it.
