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…
Northern Arizona University researchers David Trilling and Michael Mommert, while playing a well-defined role in the NASA Asteroid Initiative, are beginning to…
The task of the Single-Frequency Laser Group of the LZH almost sounds trivial: The fiber amplifiers developed by this group should be used to post-amplify a…
An international team of scientists including a Virginia Tech physicist have discovered that winds blowing from a supermassive black hole in a nearby galaxy…
The international team of researchers detected a clumpy gas stream flowing quickly outwards and blocking 90 percent of the X-rays emitted by the black hole….
There are many problems, however, where computational speed alone is insufficient to find a correct or optimal solution, for example because the parameter…
From allowing our eyes to see, to enabling green plants to harvest energy from the sun, photochemical reactions – reactions triggered by light – are both…
The finding by a team of researchers at Vienna University of Technology and Princeton University, could lead to new ways to manipulate the interaction of…
New theoretical and experimental work by researchers at the National Institute of Standards and Technology (NIST) and the University of Michigan suggests an…
This invention presents a process and an apparatus for the production of water-insoluble lignin granulates for material and energetic usage.
Pulp extraction for manufacturing paper from wood or grasses generates lignin, which has a high calorific value, in large amounts as a side-product and component of waste liquor.
The further use of lignin is prevented especially because of heterogeneity, aroma, water solubility, dust formation, and high reactivity.
That’s partly because of the complexities involved in studying the random, squiggly form DNA takes in solution. Researchers from Brown have simplified matters…
Physicists at the University of Rochester have created a silicon nanocavity that allows light to be trapped longer than in other similarly-sized optical…
Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, gently torture it over an unflickering flame until it just about reaches its…
The researchers will be reporting their results at the international Conference for Computer Vision and Pattern Recognition (CVPR) from June 24-27 in Columbus…
Pluto is an extremely distant world, orbiting the sun more than 29 times farther than Earth. With a surface temperature estimated to be about 380 degrees below…
The recipe is used for lab experiments designed to simulate Titan’s chemistry. With this approach, the team was able to classify a previously unidentified…
