  1. Chemistry

    Busy Beads: Magnetic dust takes droplets for a ride

    With a bit of dust and a magnet, chemists can shuttle drops around on a surface, an advance that could lead to chemistry labs on a chip.

  2. Materials Science

    Electronics Detox: Leadfree material for ecofriendly gadgetry

    Responding to growing concern over the disposal of electronic devices, scientists in Japan have created a lead-free piezoceramic that could replace the toxic components in many of these gadgets.

  3. Chemistry

    Fatty acid makes busy micropotter

    A fatty acid commonly found in soap and vegetable oil assembles into microscopic, potterylike structures when it crystallizes.

  4. Chemistry

    Solar Hydrogen

    With the vision of a hydrogen economy looming ever larger in people's minds, scientists have picked up the pace of their pursuit of materials that use solar energy to split water and make clean-burning hydrogen fuel.

  5. Chemistry

    Microbes Make the Switch: Tailored bacteria need caffeine product to survive

    Bacteria that rely on a chemical derived from the breakdown of caffeine for their survival could help lead to the development of decaffeinated coffee plants.

  6. Chemistry

    Branching polymer could heal cataract wounds

    Cataract surgery might get a little easier, thanks to a transparent gel that seals surgical incisions in the eye better than standard sutures do.

  7. Materials Science

    Reversible gel restores artwork

    To help conservationists restore paintings to their original glory without damaging the original paint, chemists have developed a cleaning product that switches from a liquid to a gel.

  8. Chemistry

    Breakdown: How Three Chemists Took the Prize

    The Nobel Prize in Chemistry has been awarded to three scientists for their discovery of how cells mark proteins for destruction with a molecular tag called ubiquitin, otherwise known as the kiss of death.

  9. Humans

    Nobel prizes: The sweet smell of success

    Nobel prizes in the sciences went to research on olfactory genes, subatomic particles, and the molecular kiss of death.

  10. Chemistry

    Buckyballs at Bat: Toxic nanomaterials get a tune-up

    The soccer-ball-shaped carbon molecules known as buckyballs are toxic to human cells, yet coating the particles can switch off their toxicity.

  11. Earth

    Deep Squeeze: Experiments point to methane in Earth’s mantle

    Although today's fossil fuel reserves reside in Earth's crust, a new study suggests that hydrocarbon fuel might also nestle deep in the mantle, at depths of 100 kilometers or more.

  12. Chemistry

    Bacteria send out molecular scrounger for copper

    Scientists have discovered the organic molecule that bacteria use to take up copper, which the microbes then use to chemically crack methane.
