  • The nonlinear optical process of high-order harmonic generation is usually seen in atomic gases. Now, the process has been observed in a bulk crystalline solid, with important implications for ultrafast coherent short-wavelength sources and perhaps attosecond science.

  • With the laser just over half a century old, another dream of the pioneers of this light source has been fulfilled. An atomic X-ray laser with unprecedentedly high photon energy has been demonstrated. See Letter p.488

  • Time-resolved measurements of the X-ray photoemission delay of core-level electrons using attosecond soft X-ray pulses from a free-electron laser can be used to determine the complex correlated dynamics of photoionization.

  • Pump–probe measurements conventionally achieve femtosecond time resolution for X-ray crystallography of reactive processes, but the measured structural dynamics are complex. Using coherent control techniques, we show that the ultrafast crystallographic differences of a fluorescent protein are dominated by ground-state vibrational processes that are unconnected to the photoisomerization reaction of the chromophore.

  • The textbooks say nothing can travel faster than light, not even light itself. New experiments show that this is no longer true, raising questions about the maximum speed at which we can send information.
