Could used beer yeast be the solution to heavy metal contamination in water? A study shows that yeast, an abundant waste product from breweries, can filter out even trace amounts of lead
A new analysis by researchers at MIT’s Center for Bits and Atoms (CBA) has found that inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking water supplies. The study shows that this approach can be efficient and economic, even down to part-per-billion levels of contamination. Serious […]
Atom laser creates reflective patterns similar to light
Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom of a swimming pool or through a curved wine glass. In experiments at Washington State University, scientists have developed a technique […]
