New study reveals communications potential of graphene

more »

Providing secure wireless connections and improving the efficiency of communication devices could be another application for graphene. Often touted as a wonder material, graphene is a one-atom thick layer of carbon with remarkable, record breaking properties. Until now its ability to absorb electromagnetic radiation -- energy from across the radio frequency spectrum -- was not known.

Quantum communication scheme provides guaranteed security without quantum memories

more »

(Phys.org) —Quantum mechanics offers the potential for creating communication technologies with an inherently higher security level than today's classical technologies. Using quantum digital signatures (QDS), for example, messages can be sent to multiple recipients with the guarantee that the messages cannot be forged or tampered with.

A Rainbow Pileus Cloud over Zimbabwe

more »

Yes, but how many dark clouds have a multicolored lining? Pictured, behind this darker cloud, is a pileus iridescent cloud, a group of water droplets that have a uniformly similar size and so together diffract different colors of sunlight by different amounts. The above image was taken just before sunset when it was noticed by chance by a photographer in Murambi East, near Odzi Valley and the Mtanda Range of Zimbabwe. Also captured were unusual cloud ripples above the pileus cloud. The formation of a rare pileus cloud capping a common cumulus cloud is an indication that the lower cloud is expanding upward and might well develop into a storm. In this case, however, only a few minutes after the colorful cloud was noticed, it disappeared.

When a black hole shreds a star, a bright flare tells the story

more »

A new study explains what happens during the disruption of a normal sun-like star by a supermassive black hole. The study shows why observers might fail to see evidence of the hydrogen in the star, casting doubt on a 2012 report of the disruption of an exotic helium star.

Hubble watches stars' clockwork motion in nearby galaxy

more »

Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars. According to their analysis, the central part of the neighboring galaxy, called the Large Magellanic Cloud (LMC), completes a rotation every 250 million years.
