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…
Noise-cancelling headphones have become a popular accessory for frequent flyers. By analyzing the background frequencies produced by an airplane in flight and…
Skyrmions are three-dimensional structures that occur in magnetic materials. They are magnetic vortices a few nanometers in size in which atomic elementary…
Using the principle of supersymmetry, they have developed the first supersymmetric laser array. Their findings were published recently in the journal Science.
In recent years, electronic data processing has been evolving in one direction only: The industry has downsized its components to the nanometer range. But this…
Combining a first laser pulse to heat up and “drill” through a plasma, and another to accelerate electrons to incredibly high energies in just tens of…
In 2010 substantial progress was made when the theory of percolation on interdependent networks was introduced by Prof. Shlomo Havlin and a team of researchers…
Taking their name from an intricate Japanese basket pattern, kagome magnets are thought to have electronic properties that could be valuable for future quantum…
This means that specified standards exist now for scientists in search of new heavy elements that their measurements and publications have to meet.
In August 2017, two neutron stars were observed colliding, producing gravitational waves that were detected by the American LIGO and European Virgo detectors….
As featured on the cover of the Feb. 22 issue of Science, the team produced a gas of potassium-rubidium (KRb) molecules at temperatures as low as 50 nanokelvin…
A team of researchers led by Kenichi Okada at Tokyo Tech's Department of Electrical and Electronic Engineering has devised a strategy with a clear eye on…
The THz band is a new and vast frequency resource expected to be used for future ultrahigh-speed wireless communications. IEEE Standard 802.15.3d, published in…
Einstein is commonly quoted as saying: “The most incomprehensible thing about the world is that it is comprehensible. The fact that it is comprehensible is a…
Radio astronomy reveals processes in the Universe that we cannot see with optical instruments. In this first part of the sky survey, LOFAR observed a quarter…
Rutgers and other physicists have discovered an exotic form of electrons that spin like planets and could lead to advances in lighting, solar cells, lasers and…
This year, the Bundesnetzagentur will allocate frequencies for local net-works for the first time in Germany. With the fourth version of its ˝Open5GCore˝,…
