    Molecule Sorting: Antibody membrane lends a hand

    A new membrane may make it easier to separate mixtures of drug molecules that exist in mirror-image versions into their two components.

  4. Chemistry

    A crystal takes on an unusual topology

    A single crystal exhibits the unusual topology known as a Möbius strip.

  5. Chemistry

    Oxidized plutonium reaches a higher state

    A new understanding of the basic chemistry of plutonium could affect the way nuclear waste is stored.

    Antibiotics may become harder to resist

    Drug designers have developed new tactics to make it harder for bacteria to survive exposure to antibiotics.

  8. Chemistry

    Steering reactions with light

    A light-based scheme for guiding the motion of chemical wave fronts may suggest ways to control analogous waves present in epileptic seizures and heart arrhythmias.

  9. Chemistry

    Carbon nanotubes burn when flashed

    Carbon nanotubes can ignite when exposed to an ordinary camera flash.

  10. Chemistry

    Minimotor: Single molecule does some work

    A single molecule has performed mechanical work—pulling and releasing a cantilever tip—when exposed to light.

  11. Chemistry

    Fluorine atoms used to cut nanotubes

    Researchers have found that they can cut carbon nanotubes into short, potentially useful pieces using a technique for adding groups of atoms to nanotubes.

  12. Chemistry

    Unlikely ion made in lab

    Chemists have created a molecule—the pentamethylcyclopentadienyl cation—that many researchers thought was too unstable to exist long enough to be identified or studied.
