• Songbirds offer clues to highly practiced motor skills in humans

    San Francisco - The melodious sound of a songbird may appear effortless, but his elocutions are actually the result of rigorous training undergone in youth and maintained throughout adulthood. His tune has virtually “crystallized” by maturity. The same control is seen in the motor performance of top athletes and musicians. Yet, subtle variations in highly practiced skills persist in both songbirds and humans. Now, scientists think they know why. >> Read the Full Article
  • Brain imaging and genetic studies link thinking patterns to addiction

    San Francisco - Scientists have for the first time identified brain sites that fire up more when people make impulsive decisions. In a study comparing brain activity of sober alcoholics and non-addicted people making financial decisions, the group of sober alcoholics showed significantly more "impulsive" neural activity. >> Read the Full Article

  • Mutation may cause inherited neuropathy

    Chicago - Mutations in a protein called dynein, required for the proper functioning of sensory nerve cells, can cause defects in mice that may provide crucial clues leading to better treatments for a human nerve disorder known as peripheral neuropathy, which affects about three percent of all those over age 60. >> Read the Full Article
  • Robots Taking Over The Job On Offshore Oil Drilling Platforms

    SINTEF scientist Pal Liljeback is standing in the new NOK 80 million laboratory financed by Norsk Hydro. The lab covers only 30 square metres and lies deep in the basement of one of the Electro buildings on the SINTEF/NTNU campus on Gloshaugen in Trondheim. An orange robot arm hangs from a steel beam that spans the room at ceiling height, framed by large, sky-blue support beams. >> Read the Full Article
  • Restless legs ups heart disease, stroke risk

    NEW YORK (Reuters Health) - People with restless legs syndrome, or RLS, are twice as likely as those without RLS to suffer a stroke or heart disease, and the risk is greatest in those with the most frequent and severe symptoms, according to the results of a large study. RLS is a movement disorder that causes uncomfortable sensations in the legs that worsen when a person is inactive, such as during sleep. This is not the first study to link RLS with cardiovascular disease, the study team notes in the January 1st issue of the journal Neurology. However, the prior two studies that supported an association did not use current RLS diagnostic criteria and one of them included only men. >> Read the Full Article
  • The Cosmic Bird: Triple Cosmic Collision Of Galaxies Stuns Astronomers

    Underneath the chaotic appearance of the optical Hubble images - retrieved from the Hubble Space Telescope archive - the NACO images show two unmistakable galaxies, one a barred spiral while the other is more irregular. The surprise lay in the clear identification of a third, clearly separate component, an irregular, yet fairly massive galaxy that seems to be forming stars at a frantic rate. >> Read the Full Article
  • Science's 2007 Breakthrough of the Year: Human Genetic Variation

    In 2007, researchers were dazzled by the degree to which genomes differ from one human to another and began to understand the role of these variations in disease and personal traits. Science recognized "Human Genetic Variation" as the 2007 Breakthrough of the Year, and detailed nine other of the year's most significant scientific accomplishments in its 21 December issue. >> Read the Full Article
