Spin Current Seen as it Travels Across Materials

Spin Current Seen as it Travels Across Materials

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have for the first time seen a spin current – an inherent magnetic property common to all electrons – as it travels across materials. The result, which revealed a surprising loss of current along the way, is an important step toward realizing a next-generation breed of electronics known as “spintronics.” [More]
Fresh Clues about how Nitrogen may Reveal Itself on Exoplanets

Fresh Clues about how Nitrogen may Reveal Itself on Exoplanets

Observations of nitrogen in Earth's atmosphere by a NASA spacecraft 17 million miles away are giving astronomers fresh clues to how that gas might reveal itself on faraway planets, thus aiding in the search for life. [More]
Quark-Gluon Plasma Produced Using Fewer Particles

Quark-Gluon Plasma Produced Using Fewer Particles

Researchers at the University of Kansas working with an international team at the Large Hadron Collider have produced quark-gluon plasma -- a state of matter thought to have existed right at the birth of the universe -- with fewer particles than previously thought possible. [More]

Neighboring Andromeda Galaxy has Similar Percentage of Newborn Stars Based on Mass

In a survey of NASA's Hubble Space Telescope images of 2,753 young, blue star clusters in the neighboring Andromeda galaxy (M31), astronomers have found that M31 and our own galaxy have a similar percentage of newborn stars based on mass. [More]
Scientists Create Experimental Magnetic Wormhole That Connects Two Regions of Space

Scientists Create Experimental Magnetic Wormhole That Connects Two Regions of Space

"Wormholes" are cosmic tunnels that can connect two distant regions of the universe, and have been popularised by the dissemination of theoretical physics and by works of science fiction like Stargate, Star Trek or, more recently, Interstellar. Using present-day technology it would be impossible to create a gravitational wormhole, as the field would have to be manipulated with huge amounts of gravitational energy, which no-one yet knows how to generate. In electromagnetism, however, advances in metamaterials and invisibility have allowed researchers to put forward several designs to achieve this. [More]

Scientists Closer to Solving Mystery of Mars Transformation from Having Surface Water to Dry Red Planet

Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today. [More]

Strengthening Link Between University of Bristol's Centre for Quantum Photonics and Kyoto University's Quantum Optoelectronics Laboratory

This summer we have been strengthening the link between Centre for Quantum Photonics (CQP) and the Quantum Optoelectronics Laboratory (QOL) at Kyoto University. [More]
Researchers Suggest Higher Density of Particles in One Section of Saturn’s Rings

Researchers Suggest Higher Density of Particles in One Section of Saturn’s Rings

When the sun set on Saturn's rings in August 2009, scientists on NASA's Cassini mission were watching closely. It was the equinox -- one of two times in the Saturnian year when the sun illuminates the planet's enormous ring system edge-on. The event provided an extraordinary opportunity for the orbiting Cassini spacecraft to observe short-lived changes in the rings that reveal details about their nature. [More]
