    Electronic skin senses touch

    A pressure-detecting membrane laminated onto a sheet of flexible plastic electronics may lead to artificial skin for robots.

  2. Health & Medicine

    Could refrigeration explain Crohn’s rise?

    Crohn's disease, marked by inflammation of the small intestine, could be caused by refrigeration of meats, a process that selects for hardy bacteria that handle cold temperatures well, researchers hypothesize.

    This pollutant fights lupus

    A hormone-mimicking pollutant that leaches out of some plastics appears to fight lupus.

  4. Human genes take evolutionary turns

    Researchers have identified a set of genes that has evolved an extensive pattern of alterations unique to people.

  5. Physics

    Light pulse hovers in atom capsule

    A new way to freeze light pulses in midflight preserves the pulses' optical energy and may eventually lead to using stationary light in optical circuits and quantum computers.

  6. Materials Science

    Nanowires grow on viral templates

    Researchers are using viruses to assemble semiconducting nanowires—the building blocks of future electronic circuits.

  7. Dog personality: His master’s traits

    Personality traits may vary as much from one dog to another as they do from one person to another, a new study suggests.

    Tapping sun’s light and heat to make hydrogen

    Researchers have demonstrated a highly efficient means of splitting water molecules to generate hydrogen fuel.

  9. Physics

    A Solid Like No Other: Frigid, solid helium streams like a liquid

    Frozen helium prepared in a laboratory has apparently transformed into a superfluid solid, or supersolid—a never-before-seen phase of matter that theorists predicted more than 30 years ago.

    Clear Airways: Quelling a protein stops mucus overload

    By interfering with a protein that earlier research implicated in mucus secretion, scientists have countered overstimulation of mucus secretion in the airways of mice.

    Bogged Down: Ancient peat may be missing methane source

    Massive peat bogs in Russia may have been a major source of atmospheric methane just after the end of the last ice age.

  14. 9/11’s Fatal Road Toll: Terror attacks presaged rise in U.S. car deaths

    Federal data indicate that fear of flying after the Sept. 11, 2001, terrorist attacks caused a second toll of lives on U.S. roads in the last three months of that year.
