Discovery paves way for homebrewed drugs, prompts call for regulation

UC Berkeley Science News - Mon, 05/18/2015 - 13:00
A research team led by UC Berkeley bioengineers has completed key steps needed to turn sugar-fed yeast into a microbial factory for producing morphine and potentially other drugs, including antibiotics and anticancer agents. The process could soon become as straightforward as making homebrewed beer, prompting calls for urgent regulation.

Drug perks up old muscles and aging brains

UC Berkeley Science News - Wed, 05/13/2015 - 08:28
UC Berkeley researchers have discovered that a small-molecule drug simultaneously perks up old stem cells in the brains and muscles of mice, a finding that could lead to drug interventions for humans that would make aging tissues throughout the body act young again.

Forecasting the impact of climate change, welcome or not

UC Berkeley Science News - Fri, 05/08/2015 - 11:31
Plant ecologist David Ackerly, a UC Berkeley professor of integrative biology, has calculated that some animals and plants would need to migrate as much as four miles a year to track their preferred temperature in a rapidly warming climate. He is one of the architects of the Berkeley Initiative in Global Change Biology, an ambitious research effort.

New awards fund work between U.S., Chinese women scientists

UC Berkeley Science News - Fri, 05/08/2015 - 10:00
The Chau Hoi Shuen Foundation Women in Science Program is now funding three women faculty members to allow them to collaborate with women scientists in China. The program is designed to encourage joint research projects that might not get off the ground otherwise.

Some star explosions are lopsided, X-ray telescope finds

UC Berkeley Science News - Thu, 05/07/2015 - 17:00
Based on measurements by NuSTAR's X-ray telescope, physicist Steve Boggs & colleagues found that a 1987 stellar explosion in the Large Magellanic Cloud was lopsided, providing the best proof yet that core collapse supernovas - those that produce a neutron star or pulsar - are not symmetric. The outer layers are blown off in one direction, while the neutron star rebounds in the other.

Young biologists: First time in the field, and curious about life

UC Berkeley Science News - Thu, 05/07/2015 - 13:00
Watch students who may have not have thought much about biology take their first plunge into the world of plants and wildlife on a three-day visit to the UC Natural Reserve System’s Hastings Natural History Reservation in Carmel Valley. They're in Berkeley's Biology Scholars Program, which supports underrepresented minority students pursuing the life sciences.

Human security at risk as depletion of soil accelerates, scientists warn

UC Berkeley Science News - Thu, 05/07/2015 - 11:00
Scientists warn that humans have been depleting soil nutrients at rates that are orders of magnitude greater than our current ability to replenish it. They say that fixing this imbalance is critical to global food security over the next century.

UC Berkeley scientists begin monitoring tremors on San Andreas Fault

UC Berkeley Science News - Thu, 05/07/2015 - 08:00
The first of four borehole seismometers will be installed underground in Central California to monitor faint tremors beneath the San Andreas Fault, part of UC Berkeley’s TremorScope project to determine the link between tremors and earthquakes.

Chemical Footprinting: Identifying Hidden Liabilities in Manufacturing Consumer Products In an unassuming low-rise in the Boston suburbs, Mark Rossi tinkers with a colorful dashboard on his laptop screen while his border collie putters around his feet. Rossi is the founder of BizNGO and Clean Production Action, two nonprofit collaborations of business and environmental groups to […]

Neuroscientist works to see through Alzheimer’s disease

UC Berkeley Science News - Fri, 05/01/2015 - 12:28
If early intervention is key, then so is the ability to detect even the slightest sign of neurological damage. UC Berkeley neuroscientist William Jagust is using statistical and computational approaches to refine PET scan sensitivity to identify a possible Alzheimer precursor.

Citizen science helps predict spread of sudden oak death

UC Berkeley Science News - Fri, 05/01/2015 - 00:01
Efforts to predict the emergence and spread of sudden oak death, an infectious tree-killing disease, have gotten a big boost from the work of grassroots volunteers. A joint study led by researchers at UC Berkeley and NC State reveals that years of data from SOD Blitz, a survey project in which volunteers are trained to identify symptoms of sudden oak death, led to better predictive models of the disease's spread.

Al Gore at UC Berkeley: ‘Democracy has been hacked’

Did dinosaur-killing asteroid trigger largest lava flows on Earth?

UC Berkeley Science News - Thu, 04/30/2015 - 11:30
The asteroid that slammed into the ocean off Mexico 66 million years ago and killed off the dinosaurs probably rang the Earth like a bell, triggering volcanic eruptions around the globe, according to a team of UC Berkeley geophysicists. The impact may have re-ignited the eruptions at the Deccan Traps, initiating the largest lava flows on Earth.
