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…
Rosetta is scheduled to make its closest approach to Mars at 02:57 CET on Sunday, 25 February, using the Red Planet as a gravitational brake to reduce speed…
A newly designed porous membrane, so thin it's invisible edge-on, may revolutionize the way doctors and scientists manipulate objects as small as a molecule. The 50-atom thick filter can withstand surprisingly high pressures and may be a key to better separation of blood proteins for dialysis patients, speeding ion exchange in fuel cells, creating a new environment for growing neurological stem cells, and purifying air and water in hospitals and clean-rooms at the nanoscopic level….
Most of the luminous matter, so common in most galaxies, has been stripped away, leaving behind a dark matter shadow. These intriguing galaxies-known as dwarf…
That's essentially what a collaboration of more than a dozen accelerator physicists has accomplished, using electrons for their racecars and plasma for the…
First suggested by Albert Einstein more than 100 years ago, the paradox deals with the effects of time in the context of travel at near the speed of light….
Dutch researcher Rajesh S. Pillai investigated a new way of illuminating preparations under the microscope. For example, he could investigate the…
By fusing wet and dry nanotechnologies, researchers at Rensselaer Polytechnic Institute have found a way to control the flow of water through carbon nanotube…
At the IEEE International Solid-State Circuits Symposium, Assistant Professor Hossein Hashemi of the USC Ming Hsieh department of electrical engineering will…
He will be a member of the Expedition 16 crew to the ISS. He is set to fly there on Space Shuttle (Discovery) mission STS-122 and will return home with the…
The star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star’s remaining core. Ultraviolet light from the dying…
Space suits for astronauts may get a new and better design following a University of Houston doctoral student’s locomotion stability research. Melissa…
Marc Lessard of the physics department at the University of New Hampshire was the principle investigator for the experiment to investigate various aspects of…
The new mirror packs the same 99.9 percent reflective punch as current high-grade mirrors, called distributed Bragg reflectors (DBRs), but it does so in a…
The creation of the one-stop shop for Irish Studies has been made possible as a result of a £620,000 grant from the UK’s Joint Information Services Committee…
As a result it will be possible not only to gain a thorough understanding of the processes that occur with microscopic water droplets in the zone of the fire,…
