New Technology Helps Pinpoint Sources of Water Contamination

When the local water management agency closes your favorite beach due to unhealthy water quality, how reliable are the tests they base their decisions on? As it turns out, those tests, as well as the standards behind them, have not been updated in decades. Now scientists from Lawrence Berkeley National Laboratory have developed a highly accurate, DNA-based method to detect and distinguish sources of microbial contamination in water.

Transformational X-ray Project Takes a Step Forward

A proposed upgrade to the Advanced Light Source—which would provide new views of materials and chemistry at the nanoscale with X-ray beams up to 1,000 times brighter than possible now—has cleared the first step in a Department of Energy approval process. The upgrade would enable new explorations of chemical reactions, battery performance, and biological processes.
