New Computer Codes Unlock the Secrets of Cleaner Burning Coal

March 29, 2012

Approximately half of all electricity used in the United States comes from coal. When burned, this fossil fuel emits pollutants that contribute to smog, acid rain and increased greenhouse gases in the atmosphere. But as the demand for power increases, and affordable renewable energy sources remain years away from offsetting this need, one fact is clear: Coal is here to stay, at least for the foreseeable future.

NSF to Help Campuses Embrace 'Science DMZ' Strategy

March 15, 2012

Scientists across America increasingly rely on remote instruments such as the future Large Synoptic Survey Telescope or the Large Hadron Collider (LHC), and computing facilities such as the National Energy Research Scientific Computing Center (NERSC) to conduct experiments, create simulations, and analyze data.

Researchers Discover a New Kind of Neutrino Transformation

March 5, 2012

Neutrinos, the wispy particles that flooded the universe in the earliest moments after the Big Bang, are continually produced in the hearts of stars and other nuclear reactions. Untouched by electromagnetism, they respond only to the weak nuclear force and even weaker gravity, passing mostly unhindered through everything from planets to people. Read More »

Carbon Dioxide Catchers

February 29, 2012

Approximately 45 percent of electricity used in the United States is produced by coal-burning power plants that spew carbon dioxide (CO2) into the atmosphere and contribute to global warming. To reduce this effect, many researchers are searching for porous materials to filter out the CO2 generated by these plants before it reaches the atmosphere, a process commonly known as carbon capture. But identifying these materials is easier said than done. Read More »

A Roadmap for Engineering Piezoelectricity in Graphene

February 23, 2012

Some scientists refer to graphene as the “miracle material” of the 21st century. Composed of a single sheet of carbon atoms, this material is tougher than diamond, more conductive than copper, and has potential applications in a variety of technologies. Read More »

New Mathematical Method Reveals Where Genes Switch On or Off

February 22, 2012

Developmental biologists at Stanford University, using computing resources at the U.S. Department of Energy’s National Energy Research Scientific Computing Center (NERSC), have taken a new mathematical method used in signal processing and applied it to biochemistry, using it to reveal the atomic-level details of protein–DNA interactions with unprecedented accuracy. They hope this method, called “compressed sensing,” will speed up research into where genes are turned on and off, and they expect it to have applications in many other scientific domains as well.
