CERN Can Now Produce Antihydrogen Atoms Eight Times Faster Than Before

Slashdot - Fri, 11/21/2025 - 5:00am
fahrbot-bot shares a report from Phys.org: Physicists from Swansea University have played the leading role in a scientific breakthrough at CERN, developing an innovative technique that increases the antihydrogen trapping rate by a factor of ten. The advancement, achieved as part of the international Antihydrogen Laser Physics Apparatus (ALPHA) collaboration, has been published in Nature Communications and could help answer one of the biggest questions in physics: Why is there such a large imbalance between matter and antimatter? According to the Big Bang theory, equal amounts were created at the beginning of the universe, so why is the world around us made almost entirely of matter? Antihydrogen is the "mirror version" of hydrogen, made from an antiproton and a positron. Trapping and studying it helps scientists explore how antimatter behaves, and whether it follows the same rules as matter. Producing and trapping antihydrogen is an extremely complicated process. Previous methods took 24 hours to trap just 2,000 atoms, limiting the scope of experiments at ALPHA. The Swansea-led team has changed that. Using laser-cooled beryllium ions, the team has demonstrated that it is possible to cool positrons to less than 10 Kelvin (below -263C), significantly colder than the previous threshold of about 15 Kelvin. These cooler positrons dramatically boost the efficiency of antihydrogen production and trapping -- allowing a record 15,000 atoms to be trapped in less than seven hours.

Moss Spores Survive 9 Months Outside ISS

Slashdot - Fri, 11/21/2025 - 2:00am
alternative_right shares a report from Phys.org: Inspired by moss's resilience, researchers sent moss sporophytes -- reproductive structures that encase spores -- to the most extreme environment yet: space. Their results, published in the journal iScience on November 20, show that more than 80% of the spores survived nine months outside of the International Space Station (ISS) and made it back to Earth still capable of reproducing, demonstrating for the first time that an early land plant can survive long-term exposure to the elements of space. [Lead author Tomomichi Fujita of Hokkaido University and his team] subjected Physcomitrium patens, a well-studied moss commonly known as spreading earthmoss, to a simulated a space environment, including high levels of UV radiation, extreme high and low temperatures, and vacuum conditions. They tested three different structures from the moss -- protenemata, or juvenile moss; brood cells, or specialized stem cells that emerge under stress conditions; and sporophytes, or encapsulated spores -- to find out which had the best chance of surviving in space. The researchers found that UV radiation was the toughest element to survive, and the sporophytes were by far the most resilient of the three moss parts. None of the juvenile moss survived high UV levels or extreme temperatures. The brood cells had a higher rate of survival, but the encased spores exhibited ~1,000x more tolerance to UV radiation. The spores were also able to survive and germinate after being exposed to 196C for over a week, as well as after living in 55C heat for a month.
