  1. Materials Science

    Melt-Resistant Metals: Carbon coating keeps atoms in order

    Shrink-wrapped in carbon, nanoscale metal chunks melt at extraordinarily high temperatures, suggesting carbon coatings as a route to higher heat resistance for materials and devices.

  2. Physics

    Crystal Bash: Shocking changes to light’s properties

    Prized, light-manipulating microstructures known as photonic crystals may transform light in new and technologically tantalizing ways when jolted by shock waves.

  3. Physics

    Seeking the Mother of All Matter

    World's mightiest particle collider may transform less-than-nothing into a primordial something.

  4. Physics

    Not even bismuth-209 lasts forever

    Touted in textbooks as the heaviest stable, naturally occurring isotope, bismuth-209 actually does decay but with an astonishingly long half-life of 19 billion billion years.

  5. Tech

    Tipping tiny scales

    A prototype detector based on a tiny silicon cantilever that operates in air has achieved a 1,000-fold sensitivity boost when measuring tiny quantities of chemical agents.

  6. Computing

    Minding Your Business

    By means of novel sensors and mathematical models, scientists are teaching the basics of human social interactions to computers, which should ease the ever-expanding collaboration between people and machines.

  7. Physics

    To pack a strand tight, make it a helix

    The optimal way to pack long strings into small spaces is to coil them into helices—particularly the types of helices found in proteins and perhaps DNA.

  8. Materials Science

    Blunt Answer: Cracking the puzzle of elastic solids’ toughness

    Rubbery materials prove tougher than theory predicts because cracks trying to penetrate those stretchy materials grow blunt at their tips.

  9. Physics

    Answer blows in wind, swirls in soap

    A swirling soap film gives new clues to how turbulent flows, such as the circulation of Earth's atmosphere, squander their energy.

  10. Tech

    Nanotechnologists get a squirt gun, almost

    A novel computer simulation of molecular behavior suggests that a minuscule squirt gun able to spit liquids a few hundred nanometers ought to work.

  11. Materials Science

    Between the Sheets: In reactors and nanotubes, errant atoms get a grip

    A new computer simulation predicts that neutron irradiation of graphite displaces atoms and bonds in unexpected ways.

  12. Physics

    Fusion device crosses threshold

    By sparking thermonuclear reactions, a machine called Z has joined the big leagues among potential technologies for producing power from controlled nuclear fusion.
