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.

In this lecture, Dr. Rebecca Leane will review a range of dark matter searches using celestial objects, including exoplanets, solar-system planets, the Sun, and the Earth.

This week 200 members of the Cosmic Microwave Background Stage-4 (CMB-S4) collaboration are meeting at SLAC to focus on the continuing development of this science research project. CMB-S4 and the next generation telescopes will provide measurements of the cosmic...
