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…
A German-Chinese research team has discovered a new effect that for the first time enables the creation of extremely small magnetic structures, known as…
Carbon nanotubes (CNTs), a model one-dimensional (1D) material made up entirely of carbon atoms, have attracted considerable attention ever since their…
What astronomers thought was a planet beyond our solar system, has now seemingly vanished from sight. Astronomers now suggest that a full-grown planet never…
Just like today's transistors and photodiodes replaced vacuum tubes over half a century ago, scientists are searching for a similar leap forward in design…
Why does nuclear fuel 'age'?
Only 10 years ago, scientists working on what they hoped would open a new frontier of neuromorphic computing could only dream of a device using miniature tools…
Earth observation satellites for very low altitudes, smaller, lighter, and cheaper than conventional models: These are the goals of the EU project…
CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the leadership of the University of Bern in collaboration with the…
“Einstein's General Relativity predicts that bound orbits of one object around another are not closed, as in Newtonian Gravity, but precess forwards in the…
These observations may explain this mysterious antimatter disappearance. They come from the T2K experiment conducted in Japan and in which three French…
Artificial intelligence is a very powerful tool for solving complex problems and handling huge amounts of random data. Its use allows to translate languages…
Light can be used to knock electrons out of atoms, with light particles and electrons bouncing off each other like two billiard balls – Compton scattering. Why…
In a study published April 14 in the Proceedings of the National Academy of Sciences, University of Wisconsin-Madison physicists provide an explanation for the…
Researchers developed and demonstrated for the first time a silicon-based electro-optical modulator that is smaller, as fast as and more efficient than…
Terahertz rays are electromagnetic waves, just like radio waves or light. What differentiates them is the frequency with which they oscillate: one hundred…
Electronic chips produce heat when processing data. The laptop starts to feel uncomfortably hot on the user's knees; data centers need energy-hungry cooling…
