Analysis of global fire risk shows big, fast changes ahead

Climate change is widely expected to disrupt future fire patterns around the world — with some regions, such as the western U.S., seeing more frequent fires within the next 30 years, according to a new analysis led by UC Berkeley researchers in collaboration with an international team of scientists. The study used 16 different climate-change models to produce one of the most comprehensive projections to date of how climate change might affect global fire patterns.

Hindcasting helps scientists improve forecasts for life on Earth

Scientists at UC Berkeley have launched a unique program, the Berkeley Initiative in Global Change Biology, to use hindcasting – “predicting” what happened during past episodes of climate change – to improve the reliability and accuracy of computer models that forecast how plants and animals will adapt to a changing planet.

Let it burn: Prescribed fires pose little danger to forest ecology, study says

UC Berkeley-led research is giving the green light to fighting fire with fire. An analysis of controlled burns and mechanical thinning nationwide did not find substantial ecological harm from fuel-reduction treatments used to reduce the risk of catastrophic wildfires. And with a rise in wildfires predicted in many parts of the country, researchers say more treatments are needed to manage this risk.

Tumor cells move faster through tight spaces

Tight spaces have the counterintuitive effect of aiding the spread of tumor cells, according to a new study led by UC Berkeley bioengineers. The researchers developed a 3D model to study the biophysical environment factors influencing tumor invasion and found that narrow channels gave cells traction to help them move faster. The findings have implications for certain cancers, including malignant brain tumors, which tend to infiltrate most rapidly along tissue interfaces and confined spaces, such as blood vessels and nerve tracts.

X-ray telescope to focus on hottest regions of black holes, supernovas

NASA is scheduled to launch an orbiting X-ray satellite on Wednesday, June 13, that will open a new window on the universe, allowing scientists to probe the roiling edges of black holes, exploding stars and the smallest, most frequent flares on the sun. UC Berkeley scientists and engineers helped build the instruments, will operate the satellite, and will analyze the data from supernova explosions.

Theorem unifies superfluids and other weird materials

UC Berkeley physicists Hitoshi Murayama and Haruki Watanabe have proved that counting the number of Nambu-Goldstone bosons in a material reveals the material’s behavior at low temperatures, unifying the description of weird materials such as superfluids, magnets and Bose-Einstein condensates, and allowing the design of new materials with spooky properties.

UC Berkeley students present recommendations for clean energy policy in Washington, DC

A group of students from UC Berkeley met with top energy policy makers in Washington DC to present their recommendations on developing a national clean energy plan. These recommendations were based on an extensive report that represented the culmination of a semester's worth of work in the class “Renewable Energy and Other Cleaner Fuels: Energy Policy to Save the Planet, the Country, and the Economy” co-taught by Jannifer Granholm and Steve Weissman in spring 2012.

The real culprit behind hardened arteries? Stem cells, says landmark study

Vascular diseases are actually a type of stem cell disease, according to a new study by UC Berkeley scientists. The discovery challenges a long-standing belief that smooth muscle cells contribute to clogged blood vessels, and could revolutionize research into therapies for heart attacks and strokes, which account for one in three deaths in the United States.
