NASA has called off a $30 million mission to rescue its aging Swift space telescope after Katalyst Space's Link spacecraft developed persistent control and positioning problems. The Associated Press reports: Katalyst said Link will not attempt to capture Swift and boost it to a higher orbit because of problems with controlling the spacecraft. NASA said this means the telescope will plunge through…
Moderna and Merck say their personalized mRNA melanoma vaccine significantly reduced both cancer recurrence and spread in a late-stage trial. The treatment could reach patients as soon as next year if regulators approve it. Reuters reports: Moderna developed the vaccine with Merck and tested it together with immunotherapy drug Keytruda, a widely used treatment for melanoma. [...] This is the first…
A study of more than 64,000 people born around the end of Britain's postwar sugar rationing found that those exposed to less sugar during their first 1,000 days had lower rates of five cancers decades later, including roughly 69% lower liver cancer risk and 36% lower breast cancer risk. They also "showed signs of slower biological aging" and "continued to consume less sugar and had healthier diets…
"We are in a 21st century space race," U.S. Senator Ted Cruz has said. And this week CNN noted a competition that for decades loomed in the background of geopolitics "is now roaring to the forefront," with China "demonstrating rapid advances in space technology" while the U.S. is "ratcheting up rhetoric about a looming battle for control of the cosmos." It's the fact that China plans to build a…
An anonymous reader shares this report from Space.com: On Saturday evening (Aug. 15), SpaceX set another mark, for the shortest time between orbital flights: It launched two Falcon 9 rockets just 38 minutes apart, besting its old mark - set on Aug. 31, 2024 with two Starlink missions - by 27 minutes. The first liftoff, from Florida's Cape Canaveral Space Force Station, occurred Saturday at 9:12…
Phys.org reports: Future fusion power plants aim to recreate the heart of a star here on Earth to power our future energy needs. While the core fusion plasma will burn at hundreds of millions of degrees, the surrounding structural components must handle sudden, punishing heat loads that rival the extreme temperatures faced by spacecraft upon reentry into Earth's atmosphere. Copper and its alloys…
Astronomers using the James Webb Space Telescope say they may have found a new class of object: a "black hole star," in which a black hole is wrapped in dense gas and radiates in ways that resemble an enormous star. The Guardian reports: The international team made the breakthrough after focusing their attention on a mysterious red spot in images of the early universe captured by Nasa's James Webb…
Astronomers using JWST have found three actively feeding supermassive black holes in the distant galaxy J0148-4214, seen as it existed about 1.2 billion years after the Big Bang. Two sit just 620 light-years apart near the galaxy's center and are expected to merge within a few hundred million years. Phys.org reports: Theories of galaxy evolution -- based on observations -- suggest that, early in…
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…
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…
