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…
“We have all sorts of clues about the early evolution of the solar system,” says author Dr. David Nesvorny of the Southwest Research Institute. “They come from…
In patients with clinical symptoms of overactive bladder (OAB) standard urodynamic measurements often don’t yield pathological findings. This is caused by the…
NIST plans to issue the final U.S. Government Cloud Computing Roadmap as a three-volume work. The first two volumes were posted for public comment on Nov. 1,…
A team of researchers working at the National Institute of Standards and Technology (NIST) has just concluded a 10-year-long study of the fate of neutrons in…
Essentially, they say, the tool is an electron version of the laser “optical tweezers” that have become a standard tool in biology, physics and chemistry for…
They are born when a massive star runs out of fuel and collapses under its own gravity, crushing the matter in its core and blasting away its outer layers in a…
Writing in the November 10th issue of the journal Nature, astrophysicist Mario Livio of the Space Telescope Science Institute has put to bed a growing…
Eric Bell, an associate professor in astronomy, and Colin Slater, an astronomy Ph.D. student, found Andromeda XXVIII and XXIX—that's 28 and 29. They did it…
For current models of galaxy formation, this high star production rate is difficult to explain. It could, however, serve to solve another dwarf galaxy riddle:…
Neutron stars are the last stage in the evolution of many massive stars. They represent the most extreme form of matter: the mass of a single neutron star…
They presented this result on Wednesday 9 November 2011 at the LowNu conference in Seoul, Korea. It helps determine the so-far unknown third neutrino mixing…
By jump-starting the arcs using exploding wires, as opposed to the traditional method of directly breaking down air, the researchers reduced the amount of…
The device would be more economical that using different devices to measure different types of radiation, and could limit the exposure times of clean-up…
The research group, led by electrical and computer engineering professor Xiuling Li, developed a technique to integrate compound semiconductor nanowires on…
Compression is generally thought of as something to do to data after it has been collected, but mathematicians have recently figured out a way to use similar…
