futureLaser-driven Particle Accelerator Made Ten Thousand Times Smaller

Dielectric laser accelerators (DLAs) provide a compact and cost-effective solution to this problem by driving accelerator nanostructures with visible or near-infrared (NIR) pulsed lasers, resulting in a 10,000 times reduction of scale. Current implementations of DLAs rely on free-space lasers …

astronomyGiant Lasers Flash-Freeze and Crystallize Water to Reveal Superionic Structure

Scientists from Lawrence Livermore National Laboratory (LLNL) used giant lasers to flash-freeze water into its exotic superionic phase and record X-ray diffraction patterns to identify its atomic structure for the very first time — all in just a few billionths …

franceNotre Dame Was Rebuilt After the French Revolution and Will Be Rebuilt Again

The spire of Notre Dam was previously destroyed around 1789 during the French revolution. Notre Dam was rebuilt in the 1840s and that rebuilding included a new spire. The good news is that Notre Dam was rebuilt before and it …
