A quantum “miracle material” could support magnetic switching, a team of researchers at the University of Regensburg and University of Michigan has shown. Go to Source Black holes have been fascinating subjects of study, not just because they are cosmic vacuum cleaners, but also as engines of immense power capable of extracting and redistributing energy on a staggering scale. These dark giants are often surrounded by swirling disks of gas and dust, known as accretion disks. Go to Source […] There is a big problem with quantum technology—it’s tiny. The distinctive properties that exist at the subatomic scale usually disappear at macroscopic scales, making it difficult to harness their superior sensing and communication capabilities for real-world applications, like optical systems and advanced computing. Go to Source 1,337 seconds: that was how long WEST, a tokamak run from the CEA Cadarache site in southern France and one of the EUROfusion consortium medium size Tokamak facilities, was able to maintain a plasma for on 12 February. This was a 25% improvement on the previous record time achieved with EAST, in China, a few […] An asteroid that could level a city now has a 3.1-percent chance of striking Earth in 2032, according to NASA data released Tuesday—making it the most threatening space rock ever recorded by modern forecasting. Go to Source A team of Japanese archaeologists discovered 24 new geoglyphs in Peru’s Nazca Desert, which could be among the oldest in this area according to researchers from the Yamagata University from Japan. Almost invisible on the surface, the images were obtained through 3-D scans conducted on the ground north of the city of Nazca. The […] More pocked with craters than any other object in our solar system, Jupiter’s outermost and second-biggest Galilean moon, Callisto, appears geologically unremarkable. In the 1990s, however, NASA’s Galileo spacecraft captured magnetic measurements near Callisto that suggested that its ice shell surface—much like that of Europa, another moon of Jupiter—may encase a salty, liquid water ocean. […] The European Space Agency (ESA) is ready to guide the ESA/NASA Solar Orbiter spacecraft through its closest encounter with Venus so far. Go to Source The space telescope Gaia has created the largest three-dimensional map of the Milky Way ever. On January 15, 2025, Gaia shut down after 11 years in space. But the research on data Gaia collected will continue for many years to come. Go to Source In 1974, science fiction author Larry Niven wrote a murder mystery with an interesting premise: Could you kill a man with a tiny black hole? I won’t spoil the story, though I’m willing to bet most people would argue the answer is clearly yes. Intense gravity, tidal forces, and the event horizon would surely lead […] The giant-impact hypothesis posits that billions of years ago a Mars-sized body named Theia collided with the early Earth. Go to Source Creating and sustaining fusion reactions—essentially recreating star-like conditions on Earth—is extremely difficult, and Nathan Howard, Ph.D., a principal research scientist at the MIT Plasma Science and Fusion Center (PSFC), thinks it’s one of the most fascinating scientific challenges of our time. Go to Source In a study published in Optics Express, a research group led by Prof. Fu Yuxi from Xi’an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences has developed the first room temperature holmium-doped yttrium lithium fluoride (Ho:YLF) composite thin disk laser, which can achieve high efficiency and quality continuous-wave laser output. […] When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their nuclei—has a lot to say about how they bounce off each other. This is especially true for atoms cooled to near-zero Kelvin, where quantum mechanical effects give rise to unexpected phenomena. Collisions of these cold […] Scientists are racing to develop new materials for quantum technologies in computing and sensing for ultraprecise measurements. For these future technologies to transition from the laboratory to real-world applications, a much deeper understanding is needed of the behavior near surfaces, especially those at interfaces between materials.
