Scientists Study Some Fishy Behavior to Solve an Animal Locomotion Mystery

November 5, 2013 12:18 pm | Videos | Comments

A multi-institutional research team, led by Johns Hopkins engineers, says it has solved the puzzle of why animals push in directions that don’t point toward their goal, like the side-to-side sashaying of a running lizard or cockroach.      

Crafting a Better Enzyme Cocktail to Turn Plants into Fuel Faster

November 4, 2013 2:30 pm | News | Comments

Scientists looking to create a potent blend of enzymes to transform materials like corn stalks and wood chips into fuels have developed a test that should turbocharge their efforts. The new research is part of a worldwide effort to create fuels from plants that are plentiful and aren't part of the food supply. It's possible to do this today, but the process is costly, laborious and lengthy.
