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…
Xin Guan and Hanqi Zhuang of Florida Atlantic University on Boca Raton explain how Biometrics, the technology of performing personal identification or…
In contrast to the quasi-crystals previously documented, which can only be produced under special laboratory conditions, they are simply structured polymers…
Physicists and bioengineers have developed an optical instrument allowing them to control the behavior of a worm just by shining a tightly focused beam of…
They are using sensors attached to the body to measure important parameters including movement and blood oxygen levels. The data is then passed on to a medical…
The researchers expect that with the help of sensors it will be possible to monitor the stability of the protective walls, with measurements accurate to within…
Researchers from Northwestern University and the University of Illinois at Urbana-Champaign are the first to develop a curvilinear camera, much like the human…
The matter that makes up the universe consists of particles such as electrons and protons, as well as their counterparts known as antiparticles. Particles and…
Most of our Universe consists of hydrogen atoms, which are often found under extraordinarily high pressure as high as tens of millions of times the atmospheric…
In a new study of laboratory and satellite data, researchers report a lower value of that energy, known as total solar irradiance, than previously measured and…
The scientists reported on the first successful approach to synthesizing ultrabright fluorescent mesoporous silica nanoparticles this fall in the leading…
The discovery is of special interest because it represents a rare case in which a research team was able to make an independent age determination of the planet…
M82 is a so-called starburst galaxy, where stars are forming at rates that are tens or even hundreds of times higher than in a normal galaxy. The burst of star…
The application, known as ‘Slopen’, can help developers and contractors in their work, especially before putting up a new construction in a particular area. A…
“We've been on the trail of a state of matter called a half-quantum vortex for more than three years,” said Budakian. “First proposed in the 1970s to exist in…
In a presentation at the American Astronomical Society meeting this week and a related paper in the current issue of the journal Nature, researchers say that…
The Crab Nebula, once considered to be a source of energy so stable that astronomers used it to calibrate their instruments, is dimming. LSU physicists Mike…
