Scientists have achieved a new world record by producing extraordinarily intense X-ray flashes that last just 300 attoseconds, an almost unimaginably brief period of time. Using the European XFEL, a powerful X-ray research facility, the team concentrated the flashes into an area roughly 100,000 times smaller than the cross-section of a typical human hair. By squeezing so much X-ray energy… […]

Mars may not be as geologically inactive as it appears. New evidence from mysterious gas emissions near an enormous Martian volcano suggests that heat and volcanic processes could still be present deep beneath the planet’s surface. Researchers have identified unusual concentrations of hydrogen chloride gas above fractures in the Alba Mons volcanic region. The findings suggest that gases from the… […]

Quantum physics places fundamental limits on what scientists can know about the behavior of particles. Werner Heisenberg’s famous uncertainty principle states that certain properties, such as a particle’s position and momentum, cannot both be measured with unlimited precision. This restriction is not caused by flaws in scientific instruments. It is built into the laws of nature. But position and time… […]
