Lightning formation and the conditions triggering it have long been shrouded in a cloud of mystery, but new research led by Penn State scientists is lifting the fog. Using mathematical calculations, the researchers have discovered that lightning-like discharge doesn’t require a storm cloud—it could be made inside everyday material on a lab bench. The study […] When NASA Administrator Jared Isaacman announced the revamped approach to the Artemis moon program, it was unclear whether the new mobile launcher that has been constructed over the last two years at Kennedy Space Center would ever get used. Go to Source An international team of scientists from IBM, The University of Manchester, Oxford University, ETH Zurich, EPFL and the University of Regensburg have created and characterized a molecule unlike any previously known—one whose electrons travel through its structure in a corkscrew-like pattern that fundamentally alters its chemical behavior. The work appears in Science. Go to Source […] Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it’s more difficult. This is something physicists from Poland and the UK are well aware of. To improve current simulations of high-energy particle collisions, they have developed a more accurate method for estimating the impact of calculations […] A new study by researchers at the SETI Institute suggests that stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a transmitting planet can broaden an otherwise ultra-narrow signal, spreading its power across more frequencies and making it more difficult to detect in traditional narrowband […] New research from the Department of Energy’s Oak Ridge National Laboratory, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about controlling heat flow in solid materials. The study, published in PRX Energy, shows that applying an electric field to a ceramic material changes how phonons (tiny vibrations that carry heat) […] Austin officers arrived within 56 seconds of the first 911 call, shooting and killing the suspect after he fired at police, Chief Lisa Davis said Go to Source As a space scientist, every time I go outside with my family, I tell my children to look up at the sky. The front door of our home looks southeast, and on winter nights the constellation Orion hangs majestically just above the horizon as soon as it grows dark enough to see stars. Go to […] Researchers at the University of Vienna have uncovered a surprising phenomenon: polymer chains with segments that simply fluctuate at different intensities can spontaneously develop directional, persistent motion when densely packed—even though nothing in the system points them in any particular direction. This “entropic tug of war,” driven by fundamental physical constraints, could help explain how […] The suspect fled and later rammed patrol vehicles during a confrontation with Akron police and Summit County sheriff’s deputies before he was shot Go to Source Anyone familiar with the search for alien life will have heard of the “Goldilocks Zone” around a star. This is defined as the orbital band where the temperature is just right for liquid water to pool on a rocky planet’s surface—a good approximation for what we thought of as the early conditions for life on […] Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster known as NGC 2158. Results of the study, published Feb. 25 on the arXiv pre-print server, provide essential insights into the population of binary stars in this cluster. Go to Source As officers were working to apprehend a suspect in a vehicle’s passenger seat, the driver tried to flee, striking one officer with the vehicle and carrying another inside the car Go to Source When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. By the time they pass through Earth, such cosmic ripples are barely discernible. Go to Source […] On April 8, 2024, people across the world witnessed a solar eclipse, a relatively rare event in which the moon occults (blocks out) light from the sun. To capture this event, volunteers at 143 observatories across the U.S. trained their equipment on it as part of NASA’s Eclipse Megamovie citizen science project. The images they […] |
