Fear passed in front of the sun last week, and a NASA rover saw it fly. The Mars moon Phobos, whose name means “Fear” in ancient Greek, was caught on camera by the NASA Perseverance rover on Feb. 8. The potato-shaped moon was visible in front of the sun from Percy’s current perch in Jezero … Read more
Scientists are working to build blood vessels from human cells using tiny ice sculptures — these frigid 3D forms twist and branch like real arteries and can be used as temporary scaffolds that later get melted away, to be replaced by living cells. The researchers demonstrated the first step of this blood-vessel-building process in a … Read more
For the first time, scientists have generated functional human brain tissue using a 3D printer. Scientists printed the tissue to be less than 0.01 inch (0.02 centimeter) thick, and it contains both nerve cells and supporting cells called glia. All of these cells can communicate with one another and form networks, as they would in … Read more
Researchers have discovered four gigantic seamounts towering above the seafloor surrounding South America after detecting “gravitational anomalies” given off by the massive underwater mountains. The tallest rises more than 1.5 miles (2.4 kilometers) from the seafloor, making it three times taller than the world’s tallest building Scientists aboard the Schmidt Ocean Institute’s Falkor (too) research … Read more
An 81-year-old man from Surrey became the first patient in the U.K. to receive a new “vaccine” designed to treat solid-tumor cancers, such as the skin cancer melanoma. Therapeutic cancer vaccines act as a kind of immunotherapy, meaning they help train the immune system to fight cancer cells. They’re different from vaccines that prevent cancer, … Read more
Scientists are now inspecting snagged, bagged and tagged bits and pieces from asteroid Bennu, the cosmic mother lode delivered by NASA’s Origins, Spectral Interpretation, Resource Identification and Security — Regolith Explorer mission. Known in acronymic astro-speak as OSIRIS-REx, that seven-year-long voyage brought home the goods via a sample return canister that came to full stop … Read more
A puppy has spontaneously regrown his jawbone after part of it was surgically removed because of a cancerous tumor. It is believed to be the first reported case of a dog regenerating its mandible. Veterinarians at Cornell University College of Veterinary Medicine’s Dentistry and Oral Surgery Service first diagnosed Tyson, a 3-month-old French bulldog, with … Read more
A new study has claimed that we may breach the 2 degrees Celsius (3.6 degrees Fahrenheit) climate change increase threshold by the late 2020s — almost two decades earlier than current projections. The study, published Feb. 5 in the journal Nature Climate Change, claims global surface temperatures had increased by 1.7 C (3 F) above … Read more
Very soon, a robot surgeon may begin its practice in orbit — and though it won’t quite be a metallic, humanoid machine wearing a white coat and holding a scalpel, its mission is fascinating nonetheless. On Tuesday (Jan. 30), scientists sent a slew of innovative experiments to the International Space Station (ISS) via Northrop Grumman’s … Read more
A malicious technology can trick self-driving cars into “hallucinating” phantom vehicles and veering dangerously off-course to get out of their way, researchers have discovered. The new hack, dubbed “MadRadar,” can also hide real cars from on-vehicle radar sensors and fool a self-driving car into thinking a real car has jerked off course. The scientists reported … Read more
