British researchers devise material so dark it looks like a black hole

British scientists have created a material which absorbs all but 0.035 per cent of light, a new world record, and is so dark the human eye struggles to discern what it is that it is seeing, giving the appearance of a black hole. (Credit: Surrey Nano Systems)

Boron ‘buckyball’ discovered

Researchers have shown that clusters of 40 boron atoms form a molecular cage similar to the carbon buckyball. This is the first experimental evidence that such a boron cage structure exists. (Credit: Wang lab / Brown University)

How To Measure A Sun-Like Star’s Age

Image Caption: Artist's conception of a hypothetical exoplanet orbiting a yellow, Sun-like star. Astronomers have measured the ages of 22 Sun-like stars using their spins, in a method called gyrochronology. Before now, only two Sun-like stars had measured spins and ages. (Credit: David A. Aguilar (CfA))

Growth of structure tells us how normal and dark matter scatter

The colored curves describe different velocity dependencies of the scattering strength; it is scaling as v to the nth power. The horizontal axis, k, is a measure of how separated two points in space might be; larger k corresponds to smaller physical separation. The vertical axis (technically known as a “power spectrum”) describes how correlated two points separated by a scale 1/k are; higher number mean more correlation. The one point with error bars shows that most of the models the authors consider are not very favored by the data. (Credit: C. Dvorkin, K. Blum, and M. Kamionkowski)

NASA Curiosity Rover is starting to explore dangerous new territory

The blue line added to this June 27, 2014, image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter is the edge of the ellipse that was charted as safe terrain for the rover's August 2012 landing. Curiosity is visible right on the ellipse line in the lower center of the image. This 3-sigma landing ellipse is about 4 miles long and 12 miles wide (7 kilometers by 20 kilometers). Curiosity reached the edge of it for the first time with a drive of about 269 feet (82 meters) earlier that day. (Credit: NASA)

Europe targets black holes with next big space mission

Droplets and pilot waves vs quantum mechanics

The story is that Bush et al. at MIT did some playful experiments with droplets and the conclusion is supposed to be that this strengthens the case for de Broglie’s pilot wave theory. (Credit: Motl)

New Observatory Takes Highest-Energy Particle Research to New Heights

As cosmic-ray particles are accelerated by a black hole in this artist's interpretation, they stream toward Earth as very-high-energy gamma-rays. Upon hitting the atmosphere, they produce a shower of particles that rain down on Earth. Most of these particles run out of energy before they hit sea level.
