A dead satellite can become a high-speed hazard in an orbit that is already packed with working spacecraft. That risk is why engineers at the University of Colorado Boulder are building what sounds ...

Proteins are constantly moving, but our structures of them are static. Clare Sansom talks to the researchers using free-electron lasers to make time-resolved structures Serial femtosecond ...

The Higgs boson is the most intriguing and unusual object yet discovered by fundamental science. There is no higher experimental priority for particle physics than building an electron–positron ...

Nuria Catalan Lasheras and Igor Syratchev explain why klystrons are strategically important to the future of the field – and how CERN plans to boost their efficiency above 90%. Generating power ...

Detecting a graviton — the hypothetical particle thought to carry the force of gravity — is the ultimate physics experiment. Conventional wisdom, however, says it can’t be done. According to one ...

If you’re seeing remnants of shadowy or ghost-like images on your smartphone or tablet, your device may have become a victim of screen burn-in. It’s a relatively rare phenomenon among modern ...

In this study, we propose a physical design of a compact all-optical terahertz (THz)-driven electron source. The 300-mm accelerator beamline, powered by a Joule-level laser system, can be easily ...

What is the coldest place on Earth you can think of? If your answer is the depths of Antarctica, you’re wrong. There is somewhere even colder here on Earth, in California of all places — or under it ...

Fifty years ago, neutrino beams traversing the Gargamelle bubble chamber revealed the existence of the neutral current and put the electroweak Standard Model on solid ground. Sanje Fenkart describes ...
