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 finding was made by a group of engineers headed by Deyu Li, associate professor of mechanical engineering at Vanderbilt University, and published online in…
Thermoelectric materials produce electricity by taking advantage of temperature differences on opposite sides of a material. They are currently being used in…
Optics and photonics may one day revolutionize computer technology with the promise of light-speed calculations. Storing light as memory, however, requires…
The microchip revolution has seen a steady shrinking of features on silicon chips, packing in more transistors and wires to boost chips’ speed and data…

Ground crystalline molybdenum sulfide (MoS2) has reliably proven itself as a universal and inert solid lubricant. Its lubricity could lately be outperformed by…
SOHO has spotted over 2100 comets, most of which are from what's known as the Kreutz family, which graze the solar atmosphere where they usually evaporate…
It's often called “Tycho's supernova” after the great Danish astronomer Tycho Brahe, who gained renown for his extensive study of the object. Now, years of…
Instead, researchers want to send a spacecraft to rendezvous with a comet, then fire a harpoon to rapidly acquire samples from specific locations with surgical…
The identical spacecraft, Voyager 1 and Voyager 2, were launched in the summer and programmed to pass by Jupiter and Saturn on different paths. Voyager 2 went…
Researchers have set a new world record for data transfer, helping to usher in the next generation of high-speed network technology. At the SuperComputing 2011…
