Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
A team of researchers led by Dartmouth College may have finally solved the problem of how to inexpensively improve wireless signal strength for indoor spaces…
An international team of researchers has developed a new light-based manipulation method that could one day be used to mass produce electronic components for…
Imagine a miniature device that suffuses each room in your house with a different hue of the rainbow–purple for the living room, perhaps, blue for the…
The projects on designing elements of a quantum computer and ultra-precise atomic clock based on trapped ultracold atoms and ions are being discussed. The…
The method, which has not yet been demonstrated experimentally, essentially would speed up the process of quantum entanglement in which the properties of…
In the past decade, a new type of material has attracted raising attraction: the so-called topological insulator. This class of materials exhibits a very…
“Not many real metamaterial devices have been developed,” says Elena Semouchkina, an associate professor of electrical engineering at Michigan Technological…
A future quantum computer, using “quantum bits” or qubits, might be able to solve problems which are not tractable for classical computers. Scientists are…
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,…
At the same time, comet 96P passed through a second NASA mission's view: STEREO — short for Solar and Terrestrial Relations Observatory — also watched the…
A newly developed experimental set-up allows the X-ray structure determination of biomolecules such as proteins with far smaller samples and shorter exposure…
Traditionally, researchers have sought potential biosignatures as ways of identifying inhabited worlds: byproducts from life as we know it such as oxygen or…
There's nothing new thing under the sun — except maybe light itself.
Physicists at Emory University have shown how a system of lifeless particles can become “life-like” by collectively switching back and forth between…
Researchers at the universities of Münster, Exeter and Oxford have developed a miniature “abacus” which can be used for calculating with light signals. With it…
