  1. Physics

    Hot stuff

    A plasma-based amplifier bumps up a laser's intensity by an unprecedented 20,000 times.

  2. Physics

    Not flipping out

    A single atom on a surface has favored magnetic orientations that could allow it to encode a data bit.

  3. Physics

    Electron Superhighway

    The remarkable strength and electrical properties of graphene, a chicken-wire network of carbon atoms, make it a promising new material for computer chips.

  4. Tech

    Nanotube Press: Printing technique makes nanotransistors

    A new technique for printing networks of carbon nanotubes on a wide range of surfaces is a step toward mass production of nanotubes devices.

  5. Physics

    Alliance of Opposites: Electrons and positrons make new molecule

    Positronium, consisting of electrons and their antimatter counterparts, has been made into a molecular form.

  6. Humans

    The Wealth of Nations

    Analysis of the connections among different types of economic activities explains why some countries succeed, and others fail, in diversifying their economies.

  7. Physics

    Crueltyfree: Counting photons without killing them

    A delicate quantum measurement counts photons without destroying them.

  8. Physics

    Frizzed molecular carpets

    Measurements of the speed with which heat travels along single hydrocarbon molecules could aid in the design of molecular electronics.

  9. Tech

    A Moment in the Life of a Cell: Microscopic scan images without intruding

    A laser technique similar to a CAT scan produces 3-D images of living cells without the need for chemical staining.

  10. Tech

    Uncharted atomic landscapes

    A refinement to electron microscopes enables them not only to visualize atoms but also to identify different elements.

  11. Chemistry

    Alien Pizza, Anyone?

    Although many biochemical molecules come in left-handed and right-handed versions, life on Earth uses one version exclusively, and some controversial experiments suggest this preference might not be due to chance.

  12. Physics

    Newton’s Dusty Mirror: Old experiment inspires ultrafast imaging

    An experiment devised by Isaac Newton inspires a modern successor, in which X rays capture the image of a microscopic explosion.
