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…
These gamma rays, called MEGa-rays (for mono-energetic gamma rays), are made by using a beam of fast-moving electrons to convert laser photons (light at a…

The technology describes a device for the energy transference between a flowing medium and a crankshaft which uses the kinetic energy of the flowing medium
(e.g. stream flow in rivers, ocean currents or atmospheric currents) to produce energy.

The protected technology describes a system for collision avoidance involving a car and another road user like e.g. a pedestrian or a cyclist.Further…
Though this design can't translate into an invisibility cloak for the visible spectrum, it could have implications in diagnostics, security, and communication.The cloak, designed by Cheng Sun, assistant professor of mechanical engineering at Northwestern's McCormick School of Engineering and Applied Science, uses microfabricated gradient-index materials to manipulate the reflection and refraction of light. Sun's results will be presented May 4 at CLEO: 2011, the annual Conference on Lasers and Electro-Optics….
Two researchers at the Naval Research Laboratory (NRL) have shown that the valley degree of freedom in graphene can be polarized through scattering off a line…
Like atomic-level bricklayers, researchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are using a precise atom-by-atom layering…
The new study examined the remnant of a supernova observed by the Danish astronomer Tycho Brahe in 1572. The object, dubbed Tycho for short, was formed by a…
In laboratories like CERN*, physicists observe matter and antimatter behaving in an almost identical way. Each matter particle has an equivalent antiparticle,…
