NASA has brought two of Swift’s telescopes back online after technical problems derailed a commercial mission intended to rescue the aging observatory by raising its orbit. With atmospheric drag pulling the spacecraft downward faster than expected, scientists may have only another month or two before Swift falls below a critical operating altitude.
NASA and SpaceX have delayed Crew-13 after finding an oxidizer leak in the Dragon spacecraft’s propulsion system during prelaunch preparations. Engineers are investigating the problem before the four-person crew can begin its journey to the International Space Station.
A once-nightly pill cut breathing interruptions by about 44% in a major phase 3 sleep apnea trial, while improving oxygen levels and disease severity. By strengthening the muscles that keep the airway open during sleep, AD109 could offer a new option for people unable to tolerate CPAP.
How many times do you have to fold a piece of paper to make a doughnut? After decades, a mathematician has determined the most efficient technique
Scientists discovered that human microglia, immune cells that help shape developing brain circuits, can take four to eight years to mature instead of just weeks as they do in mice. The unusually slow process may help explain how the human brain develops its remarkable complexity and cognitive abilities.
Migraine prevention drugs are more targeted than ever before, and new guidelines may help doctors predict which will work for each patient.
A new study suggests that at least 1 in 4 former NFL players who died in recent years had CTE. Concussion expert Thayne Munce puts the finding into context.
After a flawless launch, the Nancy Grace Roman Space Telescope is on a mission to solve some of the universe’s biggest mysteries
School districts are banning AI, states are limiting educational technology in classrooms, and Meta will set new “school mode” restrictions—here’s what to know
California blackworms can squeeze through narrow channels faster than they can wriggle across wide ones, a finding that may help with robot design.
Many people struggle to sleep enough at night. Surprisingly, science cannot say if adding in a nap to sleep in two blocks is healthy.
Two widely used zero-calorie sweeteners, sucralose and stevia, may have effects that linger far longer than the sweet taste itself. In mice, researchers found that both sweeteners altered the gut microbiome, reduced beneficial compounds produced by gut bacteria, and changed the activity of genes involved in metabolism and inflammation. Some of those changes were also detected in later generations that had never consumed the sweeteners themselves.
