    Quantum bell rings to electron beat

    Before the invention of the transistor, telephone switching stations clicked with the sound of small metal arms gating the flow of electricity. A new invention revives mechanical systems, but on a far smaller scale.

    German researchers have come up with a device that takes control of electricity by shuttling electrons across a gap with metronome-like regularity. The mechanism...

    Crystal listens for telltale sounds of virus

    After successfully testing a device that can hear the movement of a single virus from a drop of fluid, researchers envision a handheld instrument that could detect viral illnesses such as foot-and-mouth disease and Ebola.

    The investigators suggest that their acoustic detector could be quicker and more economical than current assays used to identify viruses in blood, saliva,...

    Hindering glutamate slows rat brain cancer

    Drugs that thwart the effect of a chemical secreted by certain cancerous brain cells could slow the growth of deadly brain tumors, a new study suggests.

    The chemical, an amino acid called glutamate, normally acts as a neurotransmitter that brain cells use to signal each other. To serve this purpose, glutamate must move cleanly between cells. However, excess glutamate spilled into the...

    It's a snake! No, a fish. An octopus?

    Whether the so-called mimic octopus could impersonate Madonna or President Bush remains unclear, but researchers say the long-armed wonder does a great sea snake and lionfish.

    The octopus, too recent a discovery to have a scientific name, prowls the silty stretches where rivers spill into the sea in Indonesia, explains Mark D. Norman of Museum Victoria in Melbourne,...
