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…
The instruments, all flying on NASA missions, are mass spectrometers, designed to take in atmospheric, rock or soil samples and identify particular molecules…
In many ways, traditional chemical synthesis is similar to cooking. To alter the final product, you can change the ingredients or their ratio, change the…
The presented invention describes a method for increasing the efficiency of solar cells of so-called hot carrier at more than 30% by the rapid separation of hot electrons and holes in each band prior to cooling. The object is solved by the use of a specially adapted for this purpose, a double hetero structure which has never been used for the separation of the hot carrier in a hot carrier solar cell.
Michael Hanspach confirmed media coverage on the topic in a radio interview with Hessischer Rundfunk yesterday. Hanspach and his colleague had successfully…
Thread-like semiconductor structures called nanowires, so thin that they are effectively one-dimensional, show potential as lasers for applications in…
Gamma-ray bursts are the most luminous explosions in the cosmos. Most are thought to be triggered when the core of a massive star runs out of nuclear fuel,…
The best answer is that some kind of electromagnetic wave coursing through the belts pushes the particles along, not unlike a wave in the ocean providing a…
As the name suggests, X-ray binaries are star systems made up of two parts: a compact stellar remnant — either a neutron star or a black hole; and a companion…
The invention relates to processes for the oligomerization of olefins, in particular of ethene, which are catalyzed by the complexes or catalyst systems in accordance with the invention.
Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern…
New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was…
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes,…
Now, computer scientists at Princeton University have developed a method that offers a solution to this data overload. Using a mathematical method that…
An international group of astronomers, including Marita Krause and Rainer Beck from Max-Planck-Institut für Radioastronomie (MPIfR) in Bonn, has found a…
This technology allows a cell manipulation system that is easy to manufacture, and the manipulation yields more reproducible results.
However, research by a team of scientists led by a Michigan State University physicist has researchers rethinking that. Scientists had long thought that…
