Fluc­tu­a­tions in the void

In quantum physics, a vacuum is not empty, but rather steeped in tiny fluctuations of the electromagnetic field. Until recently it was impossible to study those vacuum fluctuations directly. Researchers at ETH Zurich have ...

Asteroids, hydrogen make great recipe for life on Mars

A new study reveals asteroid impacts on ancient Mars could have produced key ingredients for life if the Martian atmosphere was rich in hydrogen. An early hydrogen-rich atmosphere on Mars could also explain how the planet ...

New method for better laser-material interaction

Using ultrashort laser pulses lasting a few picoseconds (trillionths of a second), Lawrence Livermore National Laboratory (LLNL) researchers have discovered an efficient mechanism for laser ablation (material removal) that ...

Scientists release most detailed map of Teton quake fault

Scientists have completed the most detailed map yet of one of North America's most spectacular geologic faults with the hope of providing a better understanding of the earthquake risk at a popular vacation destination.

New device in Z machine measures power for nuclear fusion

If you're chasing the elusive goal of nuclear fusion and think you need a bigger reactor to do the job, you first might want to know precisely how much input energy emerging from the wall plug is making it to the heart of ...

Researchers develop the next generation of endoscopy technology

Biotechnologists, physicists, and medical researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed technology for microscopic imaging in living organisms. A miniaturised multi-photon microscope, ...
