  2. Earth

    Cellulose Dreams

    Turning cellulose from plants into ethanol for fuel could help lower greenhouse-gas emissions—but the conversion is far from straightforward.

  3. Chemistry

    Mosquito Magnets

    Your skin chemicals lure blood-sucking insects to their next meal.

  4. Materials Science

    The Buck Starts Here

    The U.S. Mint performed some neat tricks to make a golden dollar.

  5. Chemistry

    Toxin in absinthe makes neurons run wild

    The alpha-thujone in absinthe—Vincent Van Gogh's favorite drink—blocks brain receptors for a natural inhibitor of nerve impulses, causing brain cells to fire uncontrollably.

  6. Chemistry

    Sensor sniffs out spoiled fish

    A new electronic nose detects amine compounds produced when fish decay.

  7. Chemistry

    Air knocks the wind out of nanotubes

    Carbon nanotubes are very sensitive to oxygen, an effect that could limit their use in open-air applications.

  8. Chemistry

    Heat spurs growth of tiny carbon trees

    Microscopic carbon forests can grow on a graphite surface without the help of catalysts.

  9. Chemistry

    Buckyballs Can Come from Outer Space

    A new analysis settles the question of whether carbon molecules found in meteorites have an extraterrestrial origin.

  10. Chemistry

    Molecules Leave Their Mark

    A material etched with tiny, carefully shaped pores can act like an artificial enzyme, cell membrane, or receptor.

  11. Chemistry

    Power cells find uses for fossil fuel

    A new fuel cell that runs on hydrocarbons such as natural gas, butane, and diesel instead of hydrogen could be an efficient, practical way to generate power without pollution.

  12. Chemistry

    Where the Gems Are

    By using a novel tool to figure out an emerald’s oxygen-isotope ratio, gemologists can now determine which mine the precious stone came from and, possibly, gain insights into the formation and history of these coveted gems.
