  • Study: Ancestor of placental mammals lived shortly after dinosaurs
    A small furry creature that evolved less than 400,000 years after dinosaurs died out could be the ancestor to more than 5,000 mammal species today, according to a study published in Science. The study looked at a database of genetic information for various species of placental mammals to determine their family trees, and found that the period after the dinosaurs disappeared was the "big bang" for the diversification of mammalian species.

  • Are bats a disease carrier for humans?
    Though rats typically get a bad rap for being carriers of diseases harmful to humans, it's bats that should really get attention, according to findings published in the Proceedings of the Royal Society B. The analysis found that bats, on average, carry 1.79 viruses that can infect humans, while rodents carry 1.48. Science News (2/7) LinkedInFacebookTwitterEmail this Story
  • Researchers discover genetic origins of Lou Gehrig's disease
    Many people who suffer from amyotrophic lateral sclerosis or frontotemporal dementia carry thousands of copies of a genetic string that ultimately produce protein strands that clump up. The clusters prevent the normal function of the protein, which helps control motor neurons. The origins of this mutation in the C9orf72 gene could be key to finding treatments for the disease, according to the study published in Science.

  • Biosensor device can diagnose diseases better than doctors
    A universal biosensor could take all the guesswork out of a visit to the doctor, leading to more accurate diagnoses and better treatments for illnesses. The PLEX-ID biosensor isolates microbes from saliva or blood to analyze a person's DNA and identify any existing diseases. The device is being used for research purposes, though researchers are hopeful a smaller version could be rolled out for use in doctor's offices.

  • Study explores how cultural information is spread among humans
    Humans are more likely to share their genes before they share their culture, according to a study published in Proceedings of the Royal Society B. The study looked at the evolution of a single story and how easily it moved from one group to another, and found that about 9% of variation happened between ethnolinguistic groups. The findings, researchers say, suggest that ideas move slowly from culture to culture. National Geographic News (2/6) LinkedInFacebookTwitterEmail this Story

  • Feds award $500,000 to N.C. alt-fuel project
    The Alternative Fuel Implementation Team for North Carolina project received $500,000 from the Department of Energy to look for ways to increase adoption of alternative fuels, including E85. In its second year, the project will develop a toolkit designed to help vehicle owners and fleet managers decide which alternative fuel will best satisfy their needs. Winston-Salem Journal (N.C.)

  • FDA finds more bogus Avastin in U.S. supply chain
    Counterfeit versions of bevacizumab, which is sold in the U.S. as Genentech's Avastin, have entered the U.S. drug supply chain, according to a warning from the FDA. The bogus drug is labeled as Roche Holding's Altuzan. That drug is not approved for sale in the U.S. Testing found one or more batches of the suspect drug lacked the active ingredient, and the fake products are linked to Medical Device King, Pharmalogical and Taranis Medical.
