alternative_right shares a report from ScienceDaily: Researchers have found a clever new way to map a part of Earth's upper atmosphere that is notoriously difficult to observe. Using orbital data from roughly 1,200 Starlink satellites, they reconstructed changes in atmospheric density about 500 kilometers above Earth. [...] The resulting density patterns also showed strong consistency with observations from the European Space Agency's SWARM satellites, which measure changes in atmospheric density along their orbital paths. The work expands on an earlier study by the same team. In that research, scientists estimated how thermospheric density changed over time and altitude using general orbital information called Two-Line Element, or TLE, data from Starlink satellites. The new analysis adds another dimension by examining how density varies horizontally across latitude and longitude, revealing more of the thermosphere's geographic structure. The findings could have practical benefits as the number of objects orbiting Earth continues to grow. More accurate information about atmospheric density can improve predictions of satellite motion, helping reduce the chance of collisions between satellites and between satellites and space debris. The technique could also eventually support near-real-time measurements of atmospheric density around satellites. Such monitoring could improve space weather forecasting and contribute to safer, more dependable satellite operations in the future.

An anonymous reader quotes a report from The Guardian: Miniature human organs and other tissues are to be grown from NHS patients' cells in a drive to improve medicine testing and reduce the number of animals used in drug development. Scientists will use the clumps of tissue to learn how diseases vary between patients, helping them identify which treatments are best for different people based on the particular pathology underlying their condition. The move marks a shift away from the traditional use of animals as models for human disease, towards what researchers believe will be more accurate and reliable tests based directly on human tissues. Researchers have been growing tiny clumps of human organs, known as organoids, for more than a decade. Tests show that pieces smaller than a millimeter can mirror key features of full-scale organs and tissues, including how they falter with disease and respond to drugs. Armed with organoids grown from diseased human tissues, scientists can investigate whether new drug candidates reverse pathological changes in all or a subset of patients, and quickly identify ineffective drugs early in the process. Historically, more than 90% of drugs that clear animal testing go on to fail in human trials, raising questions about the value of the tests. US and European medicines regulators now encourage other approaches if available. "It's going to have a major impact on the numbers of animals used and the way we develop new drugs in the future," said Matthias Zilbauer, a clinical professor of paediatric gastroenterology at the Cambridge Stem Cell Institute. "We're not saying there won't be any animal use in the near or foreseeable future, because there are still certain issues that cannot be tested in these new models, but the reduction is very real." "A lot of human diseases either do not occur in animals or occur in a different way because they're not human," added Zilbauer. "We want tests and models that can tell us which treatments work, and in what patients, and a mouse cannot tell us that."

Microsoft has been steadily scaling back its China presence, closing at least 15 branch offices and joint ventures over the past five years as Beijing favors domestic software. U.S. export controls also make it harder to grow its cloud and AI businesses, leaving the market with relatively little economic upside. Reuters reports: Microsoft took a major hit from the erosion of trust between Washington and Beijing, the five people said. China has since 2017 pushed the use of domestic software, which Beijing sees as more secure and whose quality is increasingly competitive with Windows and Office. U.S. restrictions, including export controls on advanced technology, have meanwhile hindered efforts to scale Microsoft's lucrative AI and cloud businesses in China. [...] Microsoft ultimately decided to remain because it had carved out a profitable business servicing Chinese companies like TikTok owner ByteDance, which need Western technology to manage overseas operations, according to three people familiar with the matter. The company also believed that it needed a presence to maintain access to China's world-class engineering talent, two of them said. Microsoft had also cultivated a relationship with the government that is among the deepest of any tech company, its former China head Alain Crozier told Reuters. "Because of the geopolitics ... some days it's a little bit harder, but we never had a crisis," he said. A Microsoft spokesperson did not address questions about the firm's deliberations on its China business but said it operates in a regulatory "environment that applies to every international supplier" and that it remains committed to the Chinese market. The state of Microsoft's China business reflects market competition, regulatory demands and technological trends, the company said.
