Motivated by public hazards associated with contaminated sources of drinking water, a team of scientists has successfully developed and tested tiny, glowing crystals that can detect and trap heavy-metal toxins like mercury and lead.
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.
Air Quality in San Joaquin Valley Improving: Study Shows Controls to Reduce Nitrogen Oxide Emissions Are Working
Looking strictly at the economic costs and benefits of three different roof types—black, white and “green” (or vegetated)—Berkeley Lab researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. While the high installation cost of green roofs sets them back in economic terms, their environmental and amenity benefits may at least partially mitigate their financial burden.
