• NASA's Hubble traces hidden history of Andromeda galaxy January 17, 2025
  In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way -- the magnificent Andromeda galaxy (Messier 31). It can be seen with the naked eye on a […]
• Astrophysicists reveal structure of 74 exocomet belts orbiting nearby stars in landmark survey January 17, 2025
  Astrophysicists have imaged a large number of exocomet belts around nearby stars, and the tiny pebbles within them. The crystal-clear images show light being emitted from these millimeter-sized pebbles within the belts that orbit 74 nearby stars of a wide variety of ages -- from those that are just emerging from birth to those in […]
• Three million years ago, our ancestors were vegetarian January 17, 2025
  Human ancestors like Australopithecus -- which lived around 3.5 million years ago in southern Africa -- ate very little to no meat, according to new research. This conclusion comes from an analysis of nitrogen isotope isotopes in the fossilized tooth enamel of seven Australopithecus individuals. The data revealed that these early hominins primarily relied on […]
• Fine-tuned brain-computer interface makes prosthetic limbs feel more real January 16, 2025
  Two new articles document progress in neuroprosthetic technology that lets people feel the shape and movement of objects moving over the 'skin' of a bionic hand.
• New chainmail-like material could be the future of armor January 16, 2025
  Resembling the interlocking links in chainmail, novel nanoscale material is incredibly strong and flexible. The interlocked material contains 100 trillion mechanical bonds per 1 square centimeter -- the highest density of mechanical bonds ever achieved. Small amounts of the mechanically interlocked polymer added to Ultem fibers increased the high-performance material's toughness.
