    Nonstick trick in the brain

    Getting drugs into the brain has proved to be a nanoscale puzzle: Anything bigger than 64 nanometers — about the size of a small virus — gets stuck in the space between brain cells once it gets through the blood-brain barrier. Justin Hanes of Johns Hopkins University School of Medicine and colleagues got around this rule by coating particles destined for brain cells in a dense layer of a polymer called polyethylene glycol.

    Antarctic test of novel ice drill poised to begin

    Any day now, a team of 40 scientists and support personnel expects to begin using a warm, high pressure jet of water to bore a 30 centimeter hole through 83 meters of ice. Once it breaks through to the sea below, they’ll have a few days to quickly sample life from water before the hole begins freezing up again. It's just a test. But if all goes well, in a few weeks the team will move 700 miles and bore an even deeper hole to sample for freshwater life that may have been living for eons outside even indirect contact with Earth’s atmosphere.

    Genome of a fruit besieged

    The banana genome has been unpeeled. The genetic makeup of Musa acuminata, a fertile banana species that gave rise to the seedless Cavendish and other clonal varieties people eat today, sheds light on the plant’s evolutionary history and ripening process. This information may also help researchers boost the crop’s resistance to fungal and viral pathogens […]
