  • A flock of genomes tells the tale of bird evolution

    A new genetic map of nearly all living birds has shaken the avian evolutionary tree, scattering some species to new perches and adding odd flourishes to their tales. Parrots roost closer to songbirds, a tiny wren shares a murderous lineage with the...
  • When it comes to DNA, crocodiles and birds flock together

    When it comes to DNA, crocodiles and birds flock together
    If you really want to know about birds, you have to consider the crocodile. That point was driven home this week with the release of the genomes of 45 bird species, which reassigned some perches on the avian evolutionary tree and included some seemingly...
  • L. Stephen Coles dies at 73; studied extreme aging in humans

     L. Stephen Coles dies at 73; studied extreme aging in humans
     L. Stephen Coles, a researcher who studied supercentenarians — the rare breed of humans who have managed to stay alive 110 years or more — has died. He was 73. Coles, a physician who started his medical career delivering babies but was a...
  • For some, violent criminality may be written in their genes

    In an apparent first, a study of Finnish convicts has identified genetic variations at two key sites on the genome that may distinguish extremely violent criminals from the rest of us. The two single nucleotide polymorphisms, or SNPs, that appear to...
  • Individual genetic differences may affect Ebola survival: study

    Scientists have been puzzling for years over why some people survive Ebola while many others perish. A new study provides strong evidence that individual genetic differences play a major role in whether people die from the disease. Researchers at the...
  • NSU renames Oceanographic Center for Guy Harvey

    NSU renames Oceanographic Center for Guy Harvey
    Nova Southeastern University plans to rename its Oceanographic Center in honor of wildlife artist and conservationist Guy Harvey. The decision, which will be announced later Friday, came after Harvey and his Guy Harvey Ocean Foundation provided a "very...
  • Building a better mouse to study Ebola

    Building a better mouse to study Ebola
    Scientists wearing anti-pathogen "spacesuits" and working in a government biocontainment laboratory have shown that genetically diverse strains of mice can accurately model the devastating health effects of the Ebola virus, according to new research. In...
  • Native lizard hangs tight with rapid evolution

    Native lizard hangs tight with rapid evolution
    Anybody who has lived or played in Florida likely has been called out by a finger-long lizard that taunts people with bold stares, push-ups and throat flexing. Aggressive, tough and foreign, those Cuban brown anoles also throw attitude at their close...
  • Liberal or conservative? Brain's 'disgust' reaction holds the answer

    Liberal or conservative? Brain's 'disgust' reaction holds the answer
    Think your political beliefs arise from logic and reason? Think again. A team of scientists who studied the brains of liberal, moderate and conservative people found that they could tell who leaned left and who leaned right based on how their brains...
  • Colombia condor conservation program lacks hard numbers

    Colombia condor conservation program lacks hard numbers
    Their wings spanning 10 feet or more as they glide serenely above Colombia's Andes, condors are majestic physical specimens. They have been important symbols here since pre-colonial times, when indigenous tribes saw them as messengers of the gods and...
  • Thomas A. Cebula, microbiologist and JHU professor

    Thomas A. Cebula, microbiologist and JHU professor
    Thomas A. Cebula, a lauded microbiologist who helped develop ways to speed up the identification of dangerous pathogens and taught as a visiting professor at the Johns Hopkins University, died Wednesday at Union Memorial Hospital following a heart attack....
