Astronomers have detected a strange signal coming from neutron stars that could be a new elementary particle. An unexplained excess of X-rays hints at axions, hypothetical “ghost” particles that could solve several long-standing physics puzzles. Source of Article
German scientists have restored the ability to walk in mice that had been paralyzed by a complete spinal cord injury. The team created a “designer” signaling protein and injected it into the animals’ brains, stimulating nerve cells to regenerate. Source of Article
After fears that it might require disassembly, Lockheed Martin has completed work on the Artemis I Orion spacecraft and has formally transferred possession to NASA's Exploration Ground Systems team at the Kennedy Space Center in Florida. Source of Article
It has generally been thought that electric eels are purely solitary animals, which stalk prey on their own. Now, however, scientists have described seeing the creatures hunting in packs – which only nine other fish species are known to do. Source of Article
NASA and DLR have officially called it quits on InSight's "mole." The instrument was designed to drill deep into the Martian soil, but soon hit a snag and has now been abandoned after almost two years of troubleshooting failed to resolve the issue. Source of Article
Glaucoma can cause vision loss that's currently irreversible. But now scientists have found that removing a membrane in the eye could help transplanted cells migrate into the optic nerve and repair the connections, potentially restoring lost vision. Source of Article
The gravitational waves we’ve detected so far have been like tsunamis in the spacetime sea. Now, a 13-year survey of light from pulsars scattered across the galaxy may have revealed the first hints of gentle gravitational wave background signals. Source of Article
A new reactor converts carbon monoxide into acetic acid, using tiny copper cubes as a catalyst. The device is relatively simple and can operate for long periods, allowing the unwanted waste gas to be turned into an industrially useful product. Source of Article
Scientists have observed snakes using an entirely unknown way of getting around. Brown tree snakes in Guam have been spotted climbing objects by wrapping themselves into a never-before-seen “lasso” shape. Source of Article
When an obese person really needs to lose weight, gastric bypass surgery is sometimes performed – but it's quite an invasive procedure. An experimental new implant, however, may produce similar results with much less fuss. Source of Article
