Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells. ...

Power plants draw more freshwater than any other consumer in the United States, accounting for more than 50 percent of the nation's freshwater use at about 500 billion gallons daily. To help save this water, researchers at Sandia National Laboratories have developed a new silica filter for power ...
