The ATLAS experiment measured more than expected of a trio of particles in the aftermath of proton collisions. The results will refine physicists’ understanding of our universe at the subatomic level.
Chemical reactions often involve intermediate steps that are too fast and complex for us to see – even using our most advanced scientific instruments. Combining two X-ray spectroscopy techniques has now been shown to change that.
A low-cost, recyclable powder can kill thousands of waterborne bacteria per second when exposed to sunlight. Stanford and SLAC scientists say the ultrafast disinfectant could be a revolutionary advance for 2 billion people worldwide without access to safe drinking water.
