Team to engineer algae for more productive biofuel potential

Oct. 19, 2021—Cyanobacteria, or blue-green algae, holds great promise for biofuel production because the free fatty acids they secrete are more easily recovered than those typically produced by green algae. Such fatty acids, or lipids, are readily converted into fuels. With a new $1.5 million Department of Energy grant, a three-institution team led by Professor of Chemical...

Evaluating maritime transportation amid climate uncertainty

Oct. 1, 2020—As the Arctic ocean responds to a warming climate it becomes a less icy, more viable and eventually more convenient shipping route. Maybe. Vanderbilt researchers are analyzing whether the Northern Sea Route that runs along the border of northern Russia is quicker and less costly to shippers, and weighing environmental concerns that could exacerbate already...
