The Columbia receives input from numerous sources, so any population of fish at any one site can be exposed to a myriad of substances."

...wed that in living, breathing animals, the lactate moves out of muscle cells into the blood and travels to various organs, including the liver, where it is burned with oxygen to make ATP. The heart even prefers lactate as a fuel, Brooks found. Brooks always suspected, however, that the muscle cell itself c...Formation of cellulose fibers tracked for the first time

When the microtubule tracks were disrupted with specific drugs, the cellulose synthase molecules kept moving, but they followed different, less directed patterns. "Many scientists had suspected a relationsh...Cholesterol gets 'thumbs up' for role in digit development

Unlike heat pumps that move heat by compressing and expanding large volumes of fluids, a Brownian refrigerator controls heat flow heat by striking molecules to speed them up or slow them down.
