Researchers have uncovered a counterintuitive phenomenon in collision dynamics: high-speed particles bounce back from wet walls much more strongly than expected. Integrating experimental observations with advanced numerical simulations revealed that increasing the impact speed induces a morphological transition in the post-collision liquid film, shifting it from a bridge to a dome shape. Further, it clarified […] Understanding the universe as a whole requires simulations on cosmic scales. An international team of astrophysicists, with a leading role for researchers at Leiden University, Netherlands, has now released one of the largest cosmological simulation datasets ever produced. The dataset contains more than 2.5 petabytes of simulation data—roughly equivalent to half a million HD movies. […] An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to perform high-resolution observations of the Needle galaxy. Results of the new observational campaign, presented April 15 on the arXiv preprint server, provide more insights into the properties of molecular gas in this galaxy. Go to Source From wearable technology to industrial heat recovery, thermoelectric generators which convert waste heat into electricity have an enormous range of potential applications. So far, however, designing high-performing versions of these devices has remained a painstaking task. Go to Source NASA’s Curiosity and Perseverance rovers have captured two 360-degree landscapes that highlight how the missions are revealing details of the red planet’s formation, watery past, and potential for life. Located 2,345 miles (3,775 kilometers) apart from each other on Mars—about the distance from Los Angeles to Washington, D.C.—both rovers are exploring areas that are billions […] The moon has played a huge role in the development of Earth. It stabilizes the planet, tempers dramatic climate swings, and possibly even provides the tidal heating that might have led to the first life forms. So it’s natural we would want to find a similar Earth/Luna system somewhere else in the cosmos. But astronomers […] Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications in communications and medical diagnostics. Go to Source Discovered in 2019, the material known as nickelates has intrigued researchers for its potential to become a superconductor at elevated temperatures—a property that could significantly advance such fields as quantum science and energy transmission. However, it’s a very unstable material and difficult to work with. But the lab of Professor Charles Ahn has developed a […] The sentence came after a three-week trial which ended with a jury acquitting Guy Rivera of first-degree murder, but convicting him of manslaughter, attempted murder and gun charges Go to Source Sticking with the same people might feel safe and comfortable. But a new Northwestern University study suggests it can actually trap new ideas and behaviors inside tight echo chambers. By contrast, the research, published in Communications Physics, shows that when interactions shift away from familiar contacts—and toward new ones—activity can spread more widely. Go to […] The search for next-generation electronic materials often starts with studying the Fermi surface, which serves as a map of a material’s electronic structure. Its shape varies with crystal structure, composition, and electronic band arrangement, directly impacting properties such as carrier density, magnetic behavior, and spin polarization. This makes it a crucial tool for understanding and […] “The Shift,” from Red Watch Productions documents calls for service from Michigan law enforcement agencies; the series is available to watch on YouTube Go to Source From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they “spin down.” The sun’s total angular momentum has declined as material is gradually blown off at the surface as solar wind. By observing this, astronomers have theorized the interaction between magnetic fields and plasma flow […] A rainbow reveals with colors what otherwise remains hidden: light is “refracted” by transparent matter, in this case water droplets. This same physical effect underlies many everyday technologies, like LCD screens and broadband connections based on fiber-optic cables. Light refraction is caused by an interaction between light and the atoms of matter. This brings the […] When Mauna Loa erupted in 2022, the largest lava flow headed on a path headed directly toward Daniel K. Inouye State Highway 200, also known as Saddle Road, a critical route that carries many residents from their homes on one side to their jobs on the other. Go to Source |
