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 invention relates to a sample holder to be used in cryo fluorescence microscopes or to simply and cost effectively upgrade a room temperature fluorescence microscope. The holder solves existing problems regarding thermal and mechanical stability of the sample and allows for a localization accuracy of a few hundred Angstroms.
“This is the first study directly connecting a galaxy's actively 'feeding' black hole to features found at much larger physical scales,” said lead researcher…
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops…
The research team is currently working on developing the system so that it can recognize the cause of a disturbance and can automatically identify false alarms…
Each wavelength of light from the sun inherently carries information about the kind of process that emitted the light, so looking at soft X-rays provides a new…
Stars form within collapsing fragments of cold gas clouds. As the cloud contracts under its own gravity, its central region becomes denser and hotter. By the…
That's the situation now, at least, with the Square Kilometer Array (SKA), a radio telescope planned for Africa and Australia that will have an unprecedented…
Silicon solar cells dominate 90 percent of the global photovoltaic market today, yet the record power conversion efficiency of silicon photovoltaics has…
In an experiment at the Department of Energy's SLAC National Accelerator Laboratory, scientists precisely measured the temperature and structure of aluminum as…
Like other first-generation bio-robots, the new nanobot engineered at the University of Illinois at Chicago is a far cry from Robocop. It's a robotic germ.
Some of the age’s greatest astronomers, including Hevelius — the father of lunar cartography — and Cassini, carefully documented the appearance of a new star…
Long before Mercury, Venus, Earth, and Mars formed, it seems that the inner solar system may have harbored a number of super-Earths–planets larger than Earth…
Down at the South Pole, where temperatures drop below negative 100 degrees Fahrenheit and darkness blankets the land for six months at a time, the South Pole…
Using the terahertz frequency spectrum (300 Gigahertz – 3 Terahertz) opens up the possibility for wireless communication links that can exchange terabytes of…
Celtic-Plus is launching a 4.4 million euro project to explore multiple-gigabit copper access based on G.fast, a digital subscriber line (DSL) standard for the…
Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using “twisted light.” This…
