CAD for RNA

Joint BioEnergy Institute (JBEI) researchers have developed computer assisted design (CAD)-type tools for engineering RNA components to control genetic expression in microbes. This holds enormous potential for microbial-based production of advanced biofuels, biodegradable plastics, therapeutic drugs and a host of other goods now derived from petrochemicals.

Climate change blamed for dead trees in Africa

Trees are dying in Africa’s Sahel, and human-caused climate change is to blame, according to a new study led by a scientist at UC Berkeley. Using climate change records, aerial and satellite images and field data, researchers found that one in five tree species disappeared in the past half-century. They attribute the tree deaths to the historic drops in rainfall and increased temperatures in the region.

Can ‘carbon ranching’ offset emissions in California?

Could cultivating dense fields of weeds help mitigate climate change by soaking up carbon dioxide from the atmosphere? Berkeley scientists Dennis Baldocchi and Whendee Silver are exploring that possibility in California’s agricultural heartland, the San Joaquin Valley. National Public Radio reports.

Bacteria turn switchgrass into advanced biofuels

Jay Keasling and his colleagues at the Joint BioEnergy Institute have engineered bacteria to turn switchgrass – a hard to digest plant – into gasoline, diesel and jet fuels. This could vastly reduce the cost of producing plant-based fuels to replace fuels from oil and coal.

Wood smoke from cooking fires linked to pneumonia, cognitive impacts

UC Berkeley-led researchers have found a dramatic one-third reduction in severe pneumonia diagnoses among children in homes with smoke-reducing chimneys on their cookstoves. Reducing wood smoke could have a major impact on the burden of pneumonia, the leading cause of child mortality in the world, the researchers said. A separate pilot study also found a link between prenatal maternal exposure to woodsmoke and poorer performance in markers for IQ among school-aged children.

UC Berkeley start-up creates energy-efficient buildings

In 2005, Charlie Huizenga and two UC Berkeley MBA graduates started Adura Technologies to install energy efficient wireless lighting systems in buildings. Their technology, based on innovations by UC Berkeley architects and engineers, has significantly reduced lighting costs in more than 2 million square feet of public and private buildings, including UC Berkeley’s undergraduate library.

Student finds inspiration in the clouds

UC Berkeley graduate student Greg Goldsmith may have his head in the clouds, but he is firmly grounded in the reality of global warming and the danger it poses to the Central American cloud forests he loves. He developed an elementary school curriculum as a way to help save them.

BERC symposium energizes Cal students

Record attendance at last week’s fifth-annual Energy Symposium at UC Berkeley demonstrated the swelling interest among students on campus and nationwide in bridging the gap between universities’ renewable energy research and the private sector.

CalSol zips to the finish in Aussie solar race

UC Berkeley’s Solar Vehicle Team, is one day from successfully completing the 3,000-kilometer trans-Australia World Solar Challenge, which brought 37 solar cars to the Aussie outback. This is the first time Berkeley has competed.

$2.5 million grant to fund global change research

The Berkeley Initiative in Global Change Biology was awarded a $2.5 million grant by the Gordon and Betty Moore Foundation for research focusing on global change forecasting for California ecosystems. The grant funds seven major projects involving faculty members from eight campus departments.

Modified corn genes may improve biofuel efficiency

Modified corn genes have the potential to make switch grass a much more efficient biofuel, according to new research by a team led by George Chuck of Berkeley’s College of Natural Resources. The study was published this week in the Proceedings of the National Academy of Sciences.

Lessons to be Learned from Nature in Photosynthesis

Lessons to be learned from nature could lead to the development of an artificial version of photosynthesis that would provide us with an absolutely clean and virtually inexhaustible energy source, says Berkeley Lab photosynthesis authority Graham Fleming and three international colleagues.

DOE grant to fund research into new nuclear reactors

Nuclear engineering professors Per Peterson and Ehud Greenspan are part of a $7.5 million project led by MIT and funded by the Department of Energy to research salt-cooled nuclear reactor technology. The grant is part of a larger initiative by the Department of Energy’s Nuclear Energy University Projects to maintain U.S. leadership in nuclear energy research.

Ferroelectrics could pave way for ultra-low power computing

UC Berkeley engineers have shown that by using ferroelectric materials, they can pump up the charge accumulated at a capacitor for a given voltage, a phenomenon called negative capacitance. The achievement could reduce the power draw of today’s electronics, and break the bottleneck that has stalled improvements in computer clock speed.

Success of amphibian social networking spawns Reptile BioBlitz

Photos and observations posted to the website of the Global Amphibian BioBlitz now cover more than 700 species: 10 percent of the world’s frog, toad and salamander species that the social networking effort hopes to track. This success has now spawned a Reptile BioBlitz.

There’s something in the California air

UC scientists built and worked in towers — some as tall as 1,500 feet — as part of the largest single atmospheric research effort in the state. The data they’ve collected will guide policymakers dealing with air pollution.

Storing vertebrates in the cloud

UC Berkeley is leading an effort to take information on the vertebrate collections in museums around the world and store it in the cloud for easy use by researchers and citizen scientists alike.

Fungi helped destroy forests during mass extinction 250 million years ago

The Permian extinction 250 million years ago was the largest mass extinction on record, and among the losers were conifers that originally blanketed the supercontinent of Pangaea. Now researchers say that climate change led to the proliferation of tree-killing soil fungi that helped destroy the forests – something that could happen as a consequence of global warming today.

Nuclear commission outlines new strategies for managing radioactive waste

The Blue Ribbon Commission on America’s Nuclear Future has released a draft report that recommends significant changes to the U.S. strategy for managing the country’s growing stockpile of high-level nuclear waste. Per Peterson, UC Berkeley professor and chair of nuclear engineering, is one of 15 members of the commission, which was formed in 2010 after plans to store nuclear waste at Nevada’s Yucca Mountain were halted.

In a remarkable outdoor laboratory in the Sierra, UC Merced and UC Berkeley researchers are using sensors to gather a mother lode of data to greatly improve ecological measurement and hydrologic forecasting.

Tools and Toys for Builders: New Test Center for Low-Energy Buildings

Like a giant, life-size set of building blocks, the new User Test Bed Facility will allow researchers and manufacturers to test buildings systems and components under “real-world” conditions by swapping out systems and changing configurations and then allow rigorous monitoring of performance of every key building element that impacts energy consumption.

Ecosystems take hard hit from loss of top predators

A new paper reviewing the impact of the loss of large predators and herbivores high in the food chain confirms that their decline has had cascading effects in marine, terrestrial and freshwater ecosystems throughout the world. The study, co-authored by UC Berkeley researchers, highlights the impact “apex consumers” have on the dynamics of fire, disease, vegetation growth, and soil and water quality.

Berkeley Lab researchers created tetrapod molecules of semiconductor nanocrystals and watched them break a fundamental principle of photoluminescence known as “Kasha’s rule.” The discovery holds promise for multi-color light emission technologies, including LEDs.

Magnetic memory and logic could achieve ultimate energy efficiency

Information theory dictates that a logical operation in a computer must consume a minimum amount of energy. Today’s computers consume a million times more energy per operation than this limit, but magnetic computers with no moving electrons could theoretically operate at the minimum energy, called the Landauer limit, according to UC Berkeley electrical engineers.
