Mutually assured destruction key to plant signaling

UC Berkeley Science News - Fri, 06/20/2014 - 12:08
When a plant needs to slow down its light gathering after a burst of activity, it adopts a drastic tactic: its photoreceptors, called phytochrome, destroy their regulating molecules, in turn assuring their own destruction. The discovery by Peter Quail of plant & microbial biology could have broad implications for agriculture and cancer research.

Information School team app for West African fishermen snags sustainable=fishing prize

Trolling for real-world solutions to support ocean fisheries, the U.S. State Department sponsored a "Fishackathon" at five sites across the country over the June 14-15 weekend. A team from UC Berkeley's School of Information, working out of the Monterey Bay Aquarium, took home the national grand prize for a mobile app designed to help West African fishermen.

Study suggests bees more important to crops than fertilizers

Not only do pollinators help increase crop yields, they may be even more important than fertilizers and sufficient water, according to a recent study out of UC Berkeley.

Your genes affect your betting behavior

UC Berkeley Science News - Mon, 06/16/2014 - 12:00
People playing betting games engage two main areas of the brain: the medial prefrontal cortex and the striatum. Ming Hsu of UC Berkeley and Eric Set of the University of Illinois scanned 12 genes involved in dopamine regulation in these areas and found that people's genetic variants affected how they dealt with trial-and-error learning and belief learning.

The games genes play: Algorithm helps explain sex in evolution

Jay Keasling, professor of chemical and biomolecular engineering and CEO of JBEI, has won the 2014 Renewable Energy Prize portion of the prestigious Eni Awards for his achievements in “the microbial production of hydrocarbon fuels.” The award is sponsored by Eni, a global multibillion dollar energy company headquartered in Rome.

A soil scientist’s suggestions for water-wise gardening

UC Berkeley Science News - Mon, 06/09/2014 - 15:24
As California faces the realities of drought, UC Berkeley soil scientist Stephen Andrews (a.k.a. the Dirt Dude) answers questions on how homeowners can have an attractive garden while keeping water bills in check.

Black hole tug-of-war between gravity and strong magnetic fields

UC Berkeley Science News - Wed, 06/04/2014 - 10:00
Alexander Tchekhovskoy, a UC Berkeley and Berkeley Lab postdoctoral fellow, has probed the strong magnetic fields around black holes and discovered that they can exert a force equal to the gravity pulling material into the black hole. This could cause some matter to levitate just above the object, pulled in two directions at once.

Tobacco gets a makeover as new source for biofuel

UC Berkeley Science News - Tue, 06/03/2014 - 14:52
Peggy Lemaux, UC Berkeley cooperative extension specialist, is working with Berkeley Lab and the University of Kentucky to develop a genetically engineered tobacco plant that will produce oil that can be used as a biofuel. KQED Science wrote this story about the research effort.

UC Berkeley Science News - Thu, 05/29/2014 - 11:40
A new five-year, $1.5 million grant from the Howard Hughes Medical Institute will help UC Berkeley's Biology Scholars Program share its successful strategies for supporting and retaining undergraduate biology majors throughout the Berkeley campus, in areas ranging from chemical biology to environmental science.

Five early-career faculty named 2014-15 Bakar Fellows

UC Berkeley Science News - Tue, 05/27/2014 - 11:42
Five UC Berkeley faculty members have been selected as 2014-15 Bakar Fellows. Launched in 2012, the Bakar program supports innovative research by early-career campus faculty pursuing projects that hold commercial promise. (Read background on the program here.)

Mimicking nature’s enzymes to design better catalysts

UC Berkeley Science News - Tue, 05/27/2014 - 10:32
Chemists Alexander Katz of UC Berkeley and David Dixon of the University of Alabama have taken a hint from nature's enzymes to redesign a metal catalyst so that certain binding sites can switched on or off. The feat could led to better catalysts that use less energy and produce valuable products with less wasteful by-products.

Pain killers may improve health of diabetics and the obese

UC Berkeley Science News - Thu, 05/22/2014 - 12:26
UC Berkeley and Salk researchers have found that mice lacking the capsaicin pain receptor live around 14 percent longer than other mice, and they retain a more youthful metabolism as well. Receptor blockers could not only relieve pain, but increase lifespan, improve metabolic health and help diabetics and the obese.

Observations confirm link between massive stars and weird supernovas

UC Berkeley Science News - Wed, 05/21/2014 - 12:54
Nearly three decades ago, UC Berkeley astronomer Alex Filippenko observed a weird supernova that puzzled him and his colleagues. Some theorized that it was caused by the explosion of an aged but massive star called a Wolf-Rayet star. A supernova observed last year confirms this suspicion.

Central Valley groundwater depletion raises Sierra and may trigger small earthquakes

UC Berkeley Science News - Wed, 05/14/2014 - 10:04
The weight of water pumped from California's agricultural heartland, the Central Valley, over the past 150 years was enough to allow Earth's crust to rebound upward, raising surrounding mountain ranges, the Sierra Nevada and Coast Ranges, some six inches. Winter rains and summer pumping cause annual up and down movements that could affect earthquakes on the San Andreas Fault.
