    Carbon pods are more than a pack of peas

    Researchers have found that they can manipulate the electronic properties of nanoscopic carbon structures.

  3. Physics

    Anatomy of a Lightning Ball

    Metallic fuzz, acid droplets, or other fairy dust may conjure up ball lightning (with video clips).

  4. Physics

    Balloon bursts give clue to fast cracks

    A casual observation about the edges of popped balloons may have led researchers to previously unknown features of the most common and least understood types of fractures.

  5. Materials Science

    Metallic materials made to order

    A new process for creating specifically patterned, three-dimensional microstructures could lead to new catalysts or optoelectronic devices.

  6. Materials Science

    Mammal cells make fake spider silk better

    Using long and abundant water-soluble proteins secreted by bioengineered mammal cells, scientists have spun the first artificial spider silk demonstrated to have some of the remarkable mechanical properties of the real thing.

    Flattery for Faience

    By replicating ancient materials with their own hands, researchers are gaining new insights into details of Egyptian faience manufacture that have been lost for thousands of years.

  8. Physics

    Electrons grab unexpected energy share

    When atoms or molecules react with a metal surface, even briefly, they can inject much more energy into surface electrons than previously realized.

  9. Physics

    Liquid computer takes key quantum step

    The first, rudimentary implementation of a method, called Shor's algorithm, for using quantum mechanics in computations suggests that larger-scale implementations are possible and may eventually break the codes used today to protect secret messages on the Internet and elsewhere.

    Getting Out the Thorn

    Researchers are developing new ways to improve the compatibility of implantable biomaterials in the body.

  12. Materials Science

    Can ancient stone avoid salt attacks?

    Researchers have found that a polymer coating can protect stone from damage caused by growing crystals.
