Scientists at the U.S. Department of Energy's Ames Laboratory and collaborators at Brookhaven National Laboratory and the University of Alabama at Birmingham have discovered a new light-induced switch that twists the crystal lattice of the material,.....»»
Researchers capture detailed picture of electron acceleration in one shot
Adjusting experimental methods achieved the first "single-shot" diagnosis of electron acceleration through a laser wakefield accelerator along a curved trajectory, according to a recent study led by University of Michigan researchers. The findings ar.....»»
Rewriting the armadillo family tree: A new species, plus a name change for the state mammal of Texas
While their scaly armor and long claws look vaguely reptilian, armadillos belong to the same group of mammals as sloths and anteaters. There are nearly two dozen species of armadillos, from six-inch long "pink fairies" to giant armadillos that measur.....»»
New calculation approach allows more accurate predictions of how atoms ionize when impacted by high-energy electrons
During electron-impact ionization (EII), high-energy electrons collide with atoms, knocking away one or more of their outer electrons. To calculate the probability that ionization will occur during these impacts, researchers use a quantity named the.....»»
Determining refractive index at relativistic speeds
If you studied advanced physics at high school, there's a good chance that you remember Snell's law, which states how a ray of light bends when it crosses a boundary between two media. According to this law, the ratio of the sines of the incident and.....»»

Researchers upend AI status quo by eliminating matrix multiplication in LLMs
Running AI models without matrix math means far less power consumption—and fewer GPUs? Enlarge / Illustration of a brain inside of a light bulb. (credit: Getty Images) Researchers claim to have developed a new way to r.....»»
From wild to sweet: Decoding the jujube"s genetic journey
Chinese jujube, known for its economic and nutritional significance, was domesticated from its wild ancestor. While previous studies have shed light on some aspects of its domestication, many genetic details remain unexplored. The jujube's transforma.....»»
Public health beliefs predict support for climate action, study shows
A paper published in the current issue of the Journal of Health Communication by Annenberg Public Policy Center (APPC) researchers finds evidence that holding science-consistent beliefs about the public health effects of climate change is an importan.....»»
Detecting intelligent life that"s light years away: Greenhouse gases could signal alien activity
If aliens modified a planet in their solar system to make it warmer, we'd be able to tell. A new UC Riverside study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet......»»
Quantum state mixing in photobiology: New insight from ultrafast terahertz Stark spectroscopy
The membrane protein bacteriorhodopsin is a proton pump, in which proton transport is initiated by the light-induced isomerization of the chromophore retinal. The molecular quantum states involved in this ultrafast reaction have now been characterize.....»»
Hidden mechanisms behind hermaphroditic plant self-incompatibility revealed
A new study presents an evolutionary-biophysical model that sheds new light on the evolution of the collaborative non-self recognition self-incompatibility, a genetic mechanism in plants that prevents self-fertilization and promotes cross-fertilizati.....»»
Astronomers study evolution of a giant outburst in X-ray binary EXO 2030+375
An international team of astronomers has observed an X-ray binary system known as EXO 2030+375. Results of the observation campaign, presented in a research paper published June 18 on the pre-print server arXiv, provide more insights into the evoluti.....»»
Australia"s giant lizards help save sheep from being eaten alive
Giant lizards called heath goannas could save Australian sheep farmers millions of dollars a year by keeping blowfly numbers down—and must be prioritized in conservation schemes to boost native wildlife, say researchers......»»
Egypt tomb find may shed light on ancient diseases: Ministry
A new discovery of 33 ancient tombs in Egypt's southern city of Aswan could reveal "new information on diseases" prevalent at the time, the tourism and antiquities ministry said Monday......»»
Researchers develop tuneable anti-counterfeiting material
Counterfeiters are becoming increasingly more sophisticated in forging everything from diplomas and currency to medications and artwork. While protective measures such as luminescent markings (which glow under ultraviolet light) have been around for.....»»
