Creating a New Trail to Solve an Old Problem

Ants normally distinguish friend from foe by detecting colony-specific molecules called pheromones that coat their bodies. Neil Tsutsui has identified the recognition pheromones and other chemical signals, and has shown in experiments that the ants’ behavior can be tweaked by exposing them to identical, environmentally harmless synthetic pheromones.

The Cell’s “Everywhere” Molecule

Michael Rape studies ubiqutins that form chains, “like pearls on a string,” he says. In 2008, his lab discovered a new member of this chain configuration and determined how an enzyme called Ube2S is able to assemble it inside cells. Without the Ube2S enzyme and the ubiquitin chain, he found, cells cannot divide. But with too much Ube2S – and too many ubiquitin chains – cell division runs out of control.

Computers that can identify you by your thoughts

Instead of typing your password, in the future you may only have to think your password, according to School of Information researchers. A new study explores the feasibility of brainwave-based computer authentication as a substitute for passwords.

Campus poised to join Obama’s BRAIN initiative

Three UC Berkeley scientists were among a gathering of the nation’s top scientists at the White House this morning (Tuesday, April 2) as President Barack Obama announced a major national initiative to develop new tools to create real-time traffic maps of the human brain.

Introducing the Dreambox

The Dreambox, a fabrication vending machine designed by industrial engineering and operations research Senior Will Drevno along with Haas Berkeley alumni David Pastewka and Richard Berwick, uses off-the-shelf fused deposition processes to print plastics as 3D objects.
