Scientists at the U.S. Naval Research Laboratory (NRL) have identified the true source of a magnetic effect seen in the material ruthenium dioxide (RuO₂), helping resolve an active debate in the rapidly growing field of altermagnetism. The study is published in the journal ACS Applied Materials & Interfaces. Go to Source Lunar dust remains one of the biggest challenges for a long-term human presence on the moon. Its jagged, clingy nature makes it naturally stick to everything from solar panels to the inside of human lungs. And while we have some methods of dealing with it, there is still plenty of experimentation to do here on […] After being struck, the officer fired shots in the direction of the vehicle, causing a graze wound to the driver; the three suspects, all 14 years old, were arrested following the incident Go to Source Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a sheet of paper. But quantum physics tells a different story. In reality, nature resists rigidity and forces even the simplest structures into the […] Like many scientists, theoretical physicist Andrew Strominger was unimpressed with early attempts at probing ChatGPT, receiving clever-sounding answers that didn’t stand up to scrutiny. So he was skeptical when a talented former graduate student paused a promising academic career to take a job with OpenAI. Strominger told him physics needed him more than Silicon Valley. […] Hahira Officer Caleb Abney was inside his patrol vehicle with emergency lights on when a Camaro veered onto the shoulder and struck his vehicle Go to Source Atom-thick layers of molybdenum disulfide are ideally suited for radiation-resistant spacecraft electronics, researchers in China have confirmed. In a study published in Nature, Peng Zhou and colleagues at Fudan University put a communications system composed of the material through a gauntlet of rigorous tests—including the transmission of their university’s Anthem—confirming that its performance is barely […] Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries to unravel the mysterious nature of this source. Go to Source Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency combs, which consist of equally spaced spectral lines and act as extraordinarily precise rulers for measuring light.

Today, our last common ancestor with the apes remains unknown as debate rages on for paleoanthropologists. “The evolutionary history of apes and humans is largely incomplete,” states the review. The study’s lead author, Sergio Almécija, a […] Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two neutron stars collide, they are predicted to produce gravitational waves, ripples in the fabric of spacetime that travel at the speed of light. Go to Source […] To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, entails comparing the light signals originating from distant objects and picked up by different telescopes that are at different locations, then reconstructing images using computational techniques. Go to Source […] A total lunar eclipse will cross the skies over the contiguous United States on Tuesday, March 3, turning the moon a deep reddish color in what’s commonly called a “blood moon.” Go to Source NASA is set to begin fueling 700,000 gallons of cryogenic propellant on the Space Launch System rocket at Kennedy Space Center on Thursday as it moves ahead with a test countdown of the Artemis II mission. Go to Source It will be business as usual for SpaceX when it tries to send up a rocket from the Space Coast Thursday night, but not so much for when the rocket comes back down. Go to Source |
