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 new research paper co-authored by a Virginia Tech assistant professor of physics provides a new explanation for two recent strange events that occurred in…
For more than 200 years, we have been using X-rays to look inside matter, and progressing to ever smaller structures – from crystals to nanoparticles. Now,…
Now, scientists have devised a new way to study the inner workings of astrophysical shock waves by creating a scaled-down version of the shock in the lab. They…
“These are major technical accomplishments and may prove useful in advancing energy and information technologies,” said ORNL's Ho Nyung Lee, who led the study…
There are two explanations for the origins of life's building molecules: extraterrestrial delivery, such as via meteorites; and endogenous formation. The…
Maximizing the sensitivity of measurement tools is crucial for any field of science and technology. Astronomers seek to detect remote cosmic phenomena,…
When it fires, a neuron consumes significantly more energy than an equivalent computer operation. And yet, a network of coupled neurons can continuously learn,…
Scientists have long tried to experimentally demonstrate a certain symmetry property of the weak interaction – parity violation – in molecules. So far, this…
An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links…
Quasiperiodic structures, which are ordered but are not strictly periodic, are the source of extraordinary beauty in nature, art, and science. For physicists,…
Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain…
Studies within the SMEC model suggest the existence of collective resonance, carrying many characteristics of a nearby proton-decay channel, which explains…
“Lower-limb robotic prosthetics need to execute different behaviors based on the terrain users are walking on,” says Edgar Lobaton, co-author of a paper on the…
Devices that measure electrical signals from the brain (electroencephalogram; EEG) or eyes (electrooculogram; EOG) can help diagnose conditions like epilepsy…
