  • Chromosomes may be knotted
    on October 20, 2017 at 2:16 pm

    Little is known about the structures of our genetic material, chromosomes, which consist of long strings that -- according to our experience -- should be likely to become knotted. However, up to now it has not been possible to study this experimentally. Researchers have now found that chromosomes may indeed be knotted. […]

  • Ancient DNA offers new view on saber-toothed cats' past
    on October 19, 2017 at 6:30 pm

    Researchers who've analyzed the complete mitochondrial genomes from ancient samples representing two species of saber-toothed cats have a new take on the animals' history over the last 50,000 years. The data suggest that the saber-toothed cats shared a common ancestor with all living cat-like species about 20 million years ago. The two saber-toothed cat species under study diverged from each other about 18 million years ago. […]

  • Evolution in your back garden: Great tits may be adapting their beaks to birdfeeders
    on October 19, 2017 at 6:30 pm

    A British enthusiasm for feeding birds may have caused UK great tits to have evolved longer beaks than their European counterparts, according to new research. The findings identify for the first time the genetic differences between UK and Dutch great tits which researchers were then able to link to longer beaks in UK birds. […]

  • H7N9 influenza is both lethal and transmissible in animal model for flu
    on October 19, 2017 at 6:30 pm

    In 2013, an influenza virus began circulating among poultry in China. It caused several waves of human infection and as of late July 2017, nearly 1,600 people had tested positive for avian H7N9. Nearly 40 percent of those infected had died. In 2017, a medical researcher received a sample of H7N9 virus isolated from a patient in China who had died of the flu. He and his research team subsequently began work to characterize and understand it. […]

  • Water striders illustrate evolutionary processes
    on October 19, 2017 at 6:29 pm

    How do new species arise and diversify in nature? Natural selection offers an explanation, but the genetic and environmental conditions behind this mechanism are still poorly understood. Researchers have just figured out how water striders (family Veliidae) of the genus Rhagovelia developed fan-like structures at the tips of their legs. These structures allow them to move upstream against the current, a feat beyond the abilities of other water striders that don't have fans. […]

  • Gut bacterium indirectly causes symptoms by altering fruit fly microbiome
    on October 19, 2017 at 6:27 pm

    CagA, a protein produced by the bacterium Helicobacter pylori, can alter the population of microbes living in the fruit fly gut, leading to disease symptoms, according to new research. […]

  • A mosquito's secret weapon: a light touch and strong wings
    on October 19, 2017 at 2:10 pm

    How do mosquitoes land and take off without our noticing? Using high-speed video cameras, researchers have found part of the answer: mosquitoes' long legs allow them to slowly and gently push off, but their wings provide the majority of the lift, even when fully laden with a blood meal. For comparison, mosquitoes push off with forces much less than those of an escaping fruit fly. […]

  • Declining baby songbirds need forests to survive drought
    on October 19, 2017 at 2:10 pm

    A new study aimed to identify characteristics that promote healthy wood thrush populations on US Department of Defense land. […]

  • Researchers watch in real time as fat-encased drug nanoparticles invade skin cells
    on October 19, 2017 at 2:10 pm

  • Scientists pinpoint jealousy in the monogamous mind
    on October 19, 2017 at 2:10 pm

    Scientists find that in male titi monkeys, jealousy is associated with heightened activity in the cingulate cortex, an area of the brain associated with social pain in humans, and the lateral septum, associated with pair bond formation in primates. A better understanding of jealousy may provide important clues on how to approach health and welfare problems such as addiction and domestic violence, as well as autism. […]

  • Duplications of noncoding DNA may have affected evolution of human-specific traits
    on October 18, 2017 at 5:32 pm

    Duplications of large segments of noncoding DNA in the human genome may have contributed to the emergence of differences between humans and nonhuman primates, according to new results. Identifying these duplications, which include regulatory sequences, and their effect on traits and behavior may help scientists explain genetic contributions to human disease. […]
