Ultra-fast X-ray lasers illuminate elusive atomic spins

A quick flash of light can make ordinary materials extraordinary, potentially inducing qualities such as the perfect efficiency of superconductivity even at room temperature. But these subatomic transformations are infamously ...

Dead comets and near-earth encounters

Near Earth Objects (NEOs) are asteroids or comets whose orbits sometimes bring them close to the Earth, thereby posing a potentially threat. The asteroid that struck Chelyabinsk last year was an NEO about 40 meters in diameter. ...

Chemists settle debate about conversion of light

Chemists of Utrecht University and of the Foundation for Fundamental Research on Matter (FOM) have settled the debate about a fundamental question that is relevant to the conversion of one colour into another. They demonstrated ...

Photonics: Graphene boosts on-chip light detectors

The fabrication of high-performance light detectors—important for computers and mobile devices—using graphene integrated onto a chip is reported in three independent studies published online this week in Nature Photonics.

Scientists break record for thinnest light-absorber

Stanford University scientists have created the thinnest, most efficient absorber of visible light on record. The nanosize structure, thousands of times thinner than an ordinary sheet of paper, could lower the cost and improve ...

Dense hydrogen in a new light

(Phys.org) —Hydrogen is the most abundant element in the universe. The way it responds under extreme pressures and temperatures is crucial to our understanding of matter and the nature of hydrogen-rich planets.

Herschel finds hot gas on menu for Milky Way's black hole

(Phys.org) —ESA's Herschel space observatory has made detailed observations of surprisingly hot molecular gas that may be orbiting or falling towards the supermassive black hole lurking at the center of our Milky Way galaxy.
