In the early hours of Wednesday morning, Aug. 5, the upper stage of a Falcon 9 rocket crashed into the moon in an uncontrolled collision. Go to Source For decades, astronomers have assumed that the Martian surface froze solid around 3 billion years ago and has stayed that way ever since. If this were really the case, any liquid water would have long since either been locked away underground or lost to space. Go to Source Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or package after the fact. They treat heat as a single averaged quantity to be removed in bulk, even though the heat is […] In January 2024, physicists at TU Dortmund University demonstrated a continuous time crystal in a semiconductor whose oscillations remained stable for hours. In a new study published in Nature Communications, Professor Alex Greilich and his team show that many such time crystals can form in the same material and synchronize their electron-nuclear spin oscillations. Go […] Over the last decade, researchers have developed two-dimensional materials with fascinating quantum effects that could be harnessed for next-generation technologies.

The 5.6-trillion-pixel map contains nearly 4 billion celestial objects, primarily stars and galaxies. The data is available for all to use and publicly view through the Legacy Survey Sky Viewer. Go to Source […] Skyrmions—essentially magnetic vortices—represent a promising approach in spintronics; in the future, they could serve as components in storage media or computers, potentially complementing established CMOS technologies. Researchers at Johannes Gutenberg University Mainz (JGU) have now visualized the interaction of antiferromagnetic skyrmions for the first time and shown that antiferromagnetic skyrmions move reproducibly along straight trajectories […] Appomattox County Deputy Burlie W. Duvall III “dedicated his life to protecting this community” with “courage, selflessness and commitment to duty,” Sheriff Robert Richardson said Go to Source Body camera footage shows a suspect opening fire and fatally wounding LVMPD Officer Austin Abdelnabi as he arrived on the scene and exited his vehicle Go to Source Hundreds of Venus-like planets could soon help determine why some worlds become sweltering greenhouse hellscapes while others remain capable of supporting life. But before answering that question, scientists first need to know how fast those planets are spinning. Go to Source Mirrors normally reveal what is placed in front of them, even when their curvature distorts a reflection. Researchers at the University of California, Los Angeles (UCLA) have introduced a different optical concept: a “lying mirror” that hides information carried by an input image and transforms it into a misleading, ordinary-looking pattern at the output. The […] Since it became operational in 2022, the James Webb Space Telescope (JWST) has released some truly breathtaking views of the cosmos. These images highlight how advancements since the days of the venerable Hubble Space Telescope are now providing the deepest and clearest views of the cosmos to date. The work is published on the arXiv […] The Perseid summer light show is back—and viewing conditions are especially promising for the Northern Hemisphere. Go to Source From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active matter because their components continuously use energy to generate motion, either individually or through interactions with their environment. Go […] |
