  • Rats share information by thinking in brain experiment
    Researchers connected the brains of rats thousands of miles apart through the Internet, allowing them to share information and collaborate on simple tasks. The Internet was used to interface the brains of rats in North Carolina and Brazil in one experiment. "These experiments showed that we have established a sophisticated, direct communication linkage between brains. Basically, we are creating what I call an organic computer," said lead scientist Miguel Nicolelis. The Guardian (London) (2/28) LinkedInFacebookTwitterEmail this Story
  • Earth radiation belt discovered, then disappears
    A new, temporary radiation belt appeared around the Earth last year, but was destroyed by an interplanetary shock wave, NASA scientists discovered.

  • Vertical feature observed for first time in black hole
    Astronomers watching a black hole devour its companion star in the X-ray binary system known as Swift J1357.2 have observed an unusual vertical feature in the material. "It's the first time we can resolve such [a] structure in an accretion disk, and it might be ubiquitous in X-ray binaries during the outburst state," said Jesus Corral-Santana of Spain's Astrophysical Institute of the Canary Islands.

  • Scar on duckbill dinosaur reveals how its wounds healed
    A scar found on the fossilized skin of a duckbill dinosaur shows that the creature healed much like modern-day reptiles, researchers said. Scientists believe the dinosaur, which lived about 65 millions years ago, may have gotten the wound from a Tyrannosaurus rex. "I would imagine just about every dinosaur walking around had similar scars," said paleontologist Phil Bell. National Geographic News (2/28) LinkedInFacebookTwitterEmail this Story

  • Why the sequester's R&D cuts are bad for the entire world
    The whole world will suffer as the sequester increases the threats to U.S. leadership in research and development, according to this article. Medicine is one of the main areas where the world benefits from that research and will lose out if it doesn't take place. For example, NIH cuts will hamper work on cancer treatments, a universal flu vaccine and Alzheimer's disease, NIH Director Francis Collins said.
