    Energy forest

    Thickets of microscopic silicon wires can dramatically boost the storage capacity of batteries, at least in the lab.Lithium-ion batteries power most modern portable gadgets. During use, lithium ions detach from carbon sheets in an anode and migrate to a cathode. During recharge, the lithium ions make the opposite trip.A carbon anode can accommodate about one lithium ion for every six carbon...

    While scientists have made significant progress in finding and combating the perpetrators of cancer growth, they've had less success in nailing down the proteins that facilitate the spread, or metastasis, of cancer.Scientists working with mice have now demonstrated that four proteins appear to work in concert to both grow and spread tumor cells. The proteins had turned up previously in...
