Two nearly identical materials with completely different chemical behavior. Research teams at the University of Vienna and TU Wien studied catalysts that use the energy of sunlight to produce ammonia. Surprisingly, when the three iron atoms that form tiny triangles in these catalysts are replaced by chromium atoms, the chemicalContinuar Leyendo
A study by the University of Bern and Inselspital, Bern University Hospital, has shown in mice that the effectiveness of a probiotic in alleviating intestinal inflammation depends on the animals’ existing gut microbiota. The same four-strain bacterial mixture was significantly more effective in some animals than in others. These findingsContinuar Leyendo
The candidate orbits our Sun beyond Pluto, and may be among the largest and brightest objects discovered in this region of the Solar System. Tucson, Oct 27, 2026.- In the outer reaches of our Solar System, beyond the orbit of Pluto, NSF–DOE Vera C. Rubin Observatory has spotted 2026 ED138Continuar Leyendo
The European Space Agency (ESA) has extended ongoing contracts to build four additional Galileo Second Generation (G2) satellites, ensuring the long-term continuity of the constellation and supporting the rollout of new services. With this procurement, the Galileo Second Generation fleet grows to 16 satellites. París, Oct 27, 2026.- The contractsContinuar Leyendo
Cambrigde, Oct 23, 2026.- Future Arctic winter sea ice is likely to shrink by around one million square kilometres more than previously thought, after researchers used clues from a warm period 6,000 years ago to improve the reliability of climate models. The results, reported in the journal Nature Geoscience, couldContinuar Leyendo
Before Rubin Observatory’s First Look event, its engineering camera captured exquisite details of star formation taking place in the Seagull Nebula. Tucson, Oct 22, 2026.- Two years ago this month, NSF–DOE Vera C. Rubin Observatory’s engineering test camera, named the LSST Commissioning Camera (ComCam), began capturing images of the skyContinuar Leyendo
The 2023 marine heatwave in the Northeast Atlantic broke all records, affecting marine ecosystems and the economy. In 2026, global ocean temperatures were even higher than in 2023. Researchers at the University of Bern have now investigated how long and intense marine heatwaves could become under today’s climate conditions. TheirContinuar Leyendo
New York, October 13, 2026.- There is no cure for HIV. While scientists have made considerable progress in controlling the infection, patients still must take daily antiretroviral medication for the rest of their lives. Results from a clinical trial led by Rockefeller, Imperial College London, and the University of OxfordContinuar Leyendo
For more than a quarter century, unidentified chemical signatures from a white dwarf star have laid dormant in the archive of the NASA/ESA Hubble Space Telescope, until diligent sleuthing by a young astronomer revealed something extraordinary: high amounts of the element niobium, and other unusual chemical abundances, indicating a potentialContinuar Leyendo
While searching for active compounds that influence fundamental processes in human cells, researchers at the University of Bern discovered a fungal toxin with surprising properties. The toxin shuts down the cell’s “protein factories.” The study provides important insights into one of the most fundamental biological processes – protein production –Continuar Leyendo
