Before atomic elements came together, less than a second after the Big Bang, if particles condensed into halos of matter, these halos may then have collapsed, creating the first black holes, boson stars, and so-called cannibal stars. This is the conclusion of a new study just published in Physical Review D, conducted by a team […] Mechanical Engineering Professor Alan McGaughey of Carnegie Mellon University recently coordinated the Phonon Olympics, bringing together developers and expert users to benchmark three leading open-source thermal conductivity calculation packages. Go to Source Increasing the surface area when plasma and water interact could help scale up a technology that destroys contaminants such as PFAS, detergents and microbial contaminants in drinking water, new research from the University of Michigan shows. Go to Source Researchers from the Department of Molecular Physics at the Fritz Haber Institute have demonstrated the first magneto-optical trap of a stable “closed-shell” molecule: aluminum monofluoride (AlF). They were able to cool AlF with lasers and selectively trap it in three different rotational quantum levels—breaking new ground in ultracold physics.

SALT is the largest optical telescope in the southern hemisphere. It’s been steadily revealing new science knowledge, ranging from the discovery of planets outside our solar system to understanding the unusual physics around black holes. It’s also 20 years of doing science […] Models help scientists understand everything from the particles that make up the universe to massive superstructures of galaxies at the beginning of time. But sometimes they model more mundane, though perhaps even more complex, features—including the course of human civilization. A new paper by Thomas Leppard of the International Archaeological Research Institute and his co-authors, […] During the 1240s, Richard Fishacre, a Dominican friar at Oxford University, used his knowledge of light and color to show that the stars and planets are made of the same elements found here on Earth. In so doing, he challenged the scientific orthodoxy of his day and preempted the methods and discoveries of the 21st-century […] We know of three interstellar objects (ISO) that have visited our inner solar system. Oumuamua was the first one, and it came and went in 2017. 2l/Borisov, an interstellar comet, was next, appearing in 2019. And right now, the interstellar comet 3I/Atlas is enjoying a visit to the sun-warmed inner solar system.

Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes puzzled astronomers. Black holes like these were not supposed to exist. Go to Source It’s almost become expected that many space telescopes and probes can have “extended missions.” Both Voyagers are still sending data back 40+ years after their five-year primary mission ended. But figuring out what to do with those spacecraft after their primary mission takes some negotiation. One such craft that will reach its end-of-mission in 2030 […] The new big thing in magnetics is altermagnetism, a form of magnetism that promises to power the next generation of electronics. Unlike ferromagnets, like a fridge magnet, where all internal atomic spins align to create a strong magnetic field, altermagnets have no net magnetic pull (strongly magnetic on the inside, but appears non-magnetic on the […] Researchers from Stockholm University and the Indian Institute of Science Education and Research (IISER) Mohali have reported a practical way to spot one of physics’ strangest predictions: the Unruh effect, which says that an object speeding up (accelerating) would perceive empty space as faintly warm. But, trying to heat something up by accelerating it unimaginably […] |
