  • Human migration patterns could be revealed in lice genes
    A new study of lice genes could help trace human migration patterns, researchers say. Lice found in Honduras are similar to Asian lice, while lice found in New York are closely related to those in Europe. The findings, published in the journal PLoS ONE, also recommends fighting lice locally, rather than globally, to target regional genetic differences. (2/27) LinkedInFacebookTwitterEmail this Story

  • Researchers solve mystery of ancient spiral-toothed fish
    Idaho State University researchers have built a computer model of a spiral-toothed fish dubbed Helicoprion, which lived 270 million years ago. Using CT scans, the researchers discovered that the creature's saw-like teeth were at the bottom of its jaw. "As the mouth closes, the teeth spin backwards ... so they slash through the meat that they are biting into," said researcher Leif Tapanila. BBC (2/27) LinkedInFacebookTwitterEmail this Story
  • 520 million-year-old fossil found in China
    Researchers have found one of the earliest animal fossils -- that of an arthropod called a fuxhianhuiid that lived some 520 million years ago. The fossil, found in southwest China, shows primitive limbs under the head, possibly used to sweep up food from the seafloor. The fossil also contains the earliest evidence of a nervous system extending past the head. (2/27) LinkedInFacebookTwitterEmail this Story
  • Brazilian monkeys can crack nuts like humans
    A study of Brazil's bearded capuchin monkeys has found that they not only know how to use tools, but to use them much like humans do. The monkeys take the time to place nuts on rocks so they won't roll away when the shell breaks. "It's skill in the way that we use that word to talk about human skills. It's a goal-directed activity. It's done fluidly. It's done flexibly," said study leader Dorothy Fragaszy. (2/27) LinkedInFacebookTwitterEmail this Story
  • 5 mental disorders share same gene variations, study finds
    A study published in The Lancet found four genetic markers associated with autism, attention-deficit/hyperactivity disorder, schizophrenia, bipolar disorder and major depression. Of these gene variants, researchers said two help regulate calcium levels in brain cells. While detecting these genes is not enough to predict a person's risk for psychiatric disorders, the findings offer a better understanding of the conditions, lead researcher Dr. Jordan Smoller said.

  • Researchers develop method to create hydrogen from methanol
    German researchers have discovered a catalyst that can create hydrogen from methanol, which can be stored and transported easily. The process, developed at the University of Rostock in Germany, is still in early stages, but scientists hope it can be developed to one day power fuel cells for computers, mobile phones and perhaps cars.

  • Report: Research must be linked to local needs
    Research should lead to innovation in developing countries, and not just published papers, according to the Swedish International Development Cooperation Agency. It's imperative to link research to what developing areas need in the way of innovation. "It is not enough to be in an ivory-towered world, hoping that somehow one's inquiries will find application," said researcher Amitav Rath. (2/27) LinkedInFacebookTwitterEmail this Story
