PhysicsTiny tubes tune in colors
At the right length and conductivity, ultrathin filaments of carbon known as carbon nanotubes can receive visible light waves in the same the way as larger antennas receive radio signals.

Materials ScienceReversible 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.

Materials ScienceOne-Upping Nature’s Materials
Striving for designer substances that build themselves from individual molecules.
-
PhysicsAn electron ruler gauges crystal flaws
Electrons ricocheting through a crystal now make it possible for scientists to discern shifts in crystal lattices as small as a hundredth of an atom's width.

PhysicsTo freeze this liquid, add heat
A wrong-headed mixture of liquid starch, water, and a solvent freezes when heated.

PhysicsHurrying a nuclear identity switch
Radioactive beryllium-7 atoms locked inside molecular cages decay extraordinarily quickly.

PhysicsWake Up, Little Surfers: Riding waves toward tabletop accelerators
Prospects that today's giant particle accelerators could shrink to the size of rooms look better than ever, now that new experiments have produced electron pulses of uniform energy from laser-powered accelerators that act over millimeter distances.
By Peter Weiss -
PhysicsMarrying matter and light
Physicists have created circuit components that, in a manner analogous to atoms, meld with light, opening new ways to study fundamental light-matter interactions.

PhysicsSpooky Timing: Quantum-linked photons coordinate clock ticks
Physicists have demonstrated a new technique for bringing distant clocks into closer synchronization by means of entangled photons whose quantum properties are mysteriously correlated.
By Peter Weiss -
PhysicsOrbiting relativity test gets slow start
Unexpected but necessary adjustments to a satelliteborne test of relativity theory have slashed the time available to collect data.

Materials ScienceHeat-controlled implant delivers insulin on demand
The field of drug delivery is literally heating up, with the development of a new polymer implant that releases insulin in response to changes in temperature.

PhysicsInformation, Please
Understanding whether the information swallowed by black holes is destroyed forever may provide physicists with new clues for unifying gravity and quantum theories.
