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…
What happens if one mixes cold and hot water? After some initial dynamics, one is left with lukewarm water—the system has thermalized to a new thermal…
In an average year, 20 to 50 percent of California's precipitation comes from relatively few, but extreme events called atmospheric rivers that move from over…
This finding opens a new piece of discovery space in the extrasolar planet hunt: to uncover planets as far from their central stars as Jupiter and Saturn are…
The term “plasmons” might sound like something from the soon-to-be-released new Star Wars movie, but the effects of plasmons have been known about for…
Solar winds are known for powering dangerous space weather events near Earth, which, in turn, endangers space assets. So a large interdisciplinary group of…
The light chemical element lithium is one of the few elements that is predicted to have been created by the Big Bang, 13.8 billion years ago. But understanding…
Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas? This intriguing question — the title of a talk given by MIT meteorologist Edward…
Localized conducting nanostructure fabrication by bottom-up approaches, such as focused electron or ion beam induced deposition (FEBID/ FIBID) or selective-area atomic layer deposition (SA-ALD), are more and more frequently used in different application fields. Researchers from the Goethe University Frankfurt am Main have developed a semi-automatic electrical conduction optimization process for these bottom-up techniques. The process is fully customizable, highly efficient and fast.
This invention provides a device for the agglomeration of very finely distributed solids, colloids, or fibres, especially in elutriates, pasty goods, fine particle systems, and/or liquids (pelletization equipment) with alternative reactor geometry and a new reactor design that makes it possible to improve the agglomeration of suspended particles (with a size of > 1 µm) and to increase throughput of treatable substances, such as sludge or slurry.
A Yale University analysis of one such event in a nearby galaxy provides an unprecedented look at the process. The research is described in the Astronomical…
Researchers have developed an ultrafast light-emitting device that can flip on and off 90 billion times a second and could form the basis of optical computing.
Andrea Merloni and members of his team from the Max-Planck Institute for Extraterrestrial Physics (MPE) in Garching, near Munich, were exploring the huge…
TOURMALET 100G incorporates the complete EXTOLL network technology in a single-chip solution. The EXTOLL network is a direct network, i.e. no external switches…
While reviewing the simulation results of a promising new lubricant material, Argonne researcher Sanket Deshmukh stumbled upon a phenomenon that had never been…
A method for designing materials capable of slowing the propagation of light over a broad range of wavelengths has been developed by researchers at the A*STAR…
Giant stars die a violent death. After a life of several million years, they collapse into themselves and then explode in what is known as a supernova.
