Sensors that detect radiation often pick up on the iconic “glow” - but does another signal come first? A SLAC/@Stanford University research team used ultrafast electrons & lasers with semiconductor samples to find out, leading to unexpected results: https://t.co/kmLRfhY48w https 227 views · 4 likes · 0 reposts · 0 replies Open on X →

@SLAClab The LUX-ZEPLIN collaboration has observed an unexpected signal. The immediate interpretation is "dark matter." This is the default response to any anomaly in particle physics. It is also the most speculative. Thirty years of experiments. Zero robust detections. Every "hi 902 views · 5 likes · 3 reposts · 1 replies Open on X →

@SLAClab This would be only the second known detection of a dark matter particle since Reines and Cowen detected the neutrino in 1956. 4.1K views · 31 likes · 2 reposts · 9 replies Open on X →

Could this unexpected signal be our first detection of dark matter? The LUX-ZEPLIN experiment, world-leading dark matter detector, has observed a particle interaction that is the most compelling hint of dark matter reported by the experiment to date: https://t.co/ymDirjHdmA http 51.3K views · 200 likes · 44 reposts · 16 replies Open on X →

Starting small. This photo shows a small fuel cell inside of a sample chamber at our synchrotron. The conditions inside of the sample chamber can be tuned to various pressures, allowing scientists to study fuel cells and other active chemistry under more realistic conditions. ht 994 views · 10 likes · 3 reposts · 1 replies Open on X →

Cracking the solid-state battery 🔋 Lithium-filled cracks can lead to short circuits & drain charge, but @Stanford & SLAC researchers found that compressing the battery material altered the formation & led to shorter charging times + longer battery life: https://t.co/kXc85pyKIk h 1.1K views · 18 likes · 4 reposts · 0 replies Open on X →
