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…

“It might explain why we’re here at all,” said David Radford, who oversees specific ORNL activities in the Majorana Demonstrator research effort. “It could…
The display, whose diagonal dimension is 1.5 meters, can show all of the data and facts that are necessary for decision-making. At the heart of this solution…
Anaglyph printing — think of the red-and-blue 3D glasses used to transform 2D images to 3D images in comics, magazines, books, and newspapers — came into…
Storing light in a bottle is easier than one might think: Laser light can be coupled into an optical glass fiber in such a way that it does not travel along…
The celebrated efficiency and versatility of LEDs—and other solid-state technologies including laser diodes and solar photovoltaics—make them increasingly…
Things not always run smoothly. It may happen, actually, that when an object slides on another, the advancement may occur through a 'stop and go' series in the…
How much light has been emitted by all galaxies since the cosmos began? After all, almost every photon (particle of light) from ultraviolet to far infrared…
This invention, by the Leibniz Institute for Agricultural Engineering in Bornim, Potsdam, features a machine for separating, classifying and purifying natural…
The basic principle of all solar cells is the spatial separation of paired photoinduced charge carriers in a photoactive region. Common photovoltaic planar…
Lausitz University of Applied Sciences invented a process for heating and/or cooling structures built on or near water. The novel process permits to reduce…
The present invention permits to produce biocoal by charging coal particles with minerals obtained from the processing fluid of biogas plants. The invention is…
“The nebula is not like a bagel, but rather, it's like a jelly doughnut, because it's filled with material in the middle,” said C. Robert O'Dell of Vanderbilt…
A major campaign using NASA's Chandra X-ray Observatory and several other satellites shows magnetars may be more diverse – and common – than previously thought.
In the quest for new cancer drugs, this software supports the full workflow from cell detection to visualization and exploration. As live cells are studied,…
