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.
Twelve years after a breakthrough discovery in his University of California, Berkeley, laboratory, professor of chemical engineering Jay Keasling is seeing his dream come true.
The vast region of Africa known as the Sahel will descend into large-scale drought, famine, war and terrorist control if immediate, coordinated steps are not taken to avert the perfect storm of climate change and the most rapidly growing population in the world.
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.
Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) through support from the Energy Biosciences Institute (EBI) have literally shed new light on cellulase catalysis.
One often ignored consequence of global climate change is that the Northern Hemisphere is becoming warmer than the Southern Hemisphere, which could significantly alter tropical precipitation patterns, according to a new study by climatologists from the University of California, Berkeley, and the University of Washington, Seattle.
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.
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.
Lab tests that detect prostate cancer can’t reveal if the cancer poses a real risk. It looks for elevated levels of a protein called PSA, but about 80 percent of cancers that generate high PSA levels grow so slowly and may never need treatment. New research by Amy Herr points the way to a much more refined assessment of proteins and the promise of better diagnosis and treatment of a range of diseases.
