Computing Tools Speed Search for New Porous Materials
A team of researchers from Lawrence Berkeley National Laboratory and the University of California at Berkeley are building a suite of computational tools to help in the search for new porous materials. These synthetically created materials can play key roles in physical and chemical processes, including petroleum refinement, water softening and in separations. One class, known as zeolites, has a commercial impact of about $350 billion annually. Read More »
Ten Billion Light Years Away, A Gang of Supernovae Reveals a Cosmic Secret
An international team of astronomers has exposed the largest sample of distant supernovae ever found—150 events, many of which are located about 10 billion light years away from Earth. These events reveal that a particular breed of cosmic explosions, called Type 1a supernovae, occurred five times more frequently when the universe was young than they do today. The paper, authored by a team of American, Israeli and Japanese astronomers, was published in the October 2011 issue of Monthly Notices of the Royal Astronomical Society (MNRAS). Read More »

Accelerating Advanced Material Development
New materials are crucial to building a clean energy economy—for everything from batteries to photovoltaics to lighter weight vehicles—but today the development cycle is too slow: around 18 years from conception to commercialization. To speed up this process, a team of researchers from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Massachusetts Institute of Technology (MIT) teamed up to develop a new computational tool. Called the Materials Project, it launches this month. Read More »
Experimental Mathematics: Computing Power Leads to Insights
Providence, RI—In his 1989 book "The Emperor's New Mind," Roger Penrose commented on the limitations on human knowledge with a striking example: He conjectured that we would most likely never know whether a string of 10 consecutive 7s appears in the digital expansion of the number pi. Just 8 years later, Yasumasa Kanada used a computer to find exactly that string, starting at the 17387594880th digit of pi. Penrose was certainly not alone in his inability to foresee the tremendous power that computers would soon possess. Read More »
Computational Research Division Announces Reorganization
David Brown, who recently joined Berkeley Lab as director of the Computational Research Division (CRD), announced a reorganization of the division on Oct. 12. The reorganization is aimed at balancing the size and research areas of the departments within CRD. Read More »
NERSC Played Key Role in Nobel Laureate’s Discovery
In the 1990s, Saul Perlmutter discovered that the universe is expanding at an accelerating rate. He confirmed his observational conclusions by running thousands of simulations at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (Berkeley Lab). As a result of this groundbreaking work, Perlmutter was awarded the 2011 Nobel Prize in Physics. His research team is believed to have been the first to use supercomputers to analyze and validate observational data in cosmology. This melding of computational science and cosmology sowed the seeds for more projects, establishing Berkeley Lab and NERSC as centers for the emerging field. Read More »
Turning Grass into Gas for Less
Pull up to the pump these days and chances are your gas will be laced with ethanol, a biofuel made from corn. Corn-ethanol is relatively easy to make, but with growing populations and shrinking farmland, there will never be enough of the starchy food crop to both feed and fuel the world. Read More »
A Better Lithium-ion Battery on the Way
Lithium-ion batteries are everywhere, in smart phones, laptops, an array of other consumer electronics, and the newest electric cars. Good as they are, they could be much better, especially when it comes to lowering the cost and extending the range of electric cars. To do that, batteries need to store a lot more energy. Read More »
