Cosmologists have detected curling patterns in the faint glow of the universe's oldest light that appear to be traces left by cosmic inflation, an exponential expansion of the universe thought to have occurred fractions of a second after the Big Bang, they announced today.

Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be "tuned" to particular frequencies and amplitudes by varying the number of layers of crystal, they report in the early online edition of Science March 7.

The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these chemicals overnight along the coast, a team of atmospheric chemists reports in the early online edition of the Proceedings of the National Academy of Sciences the week of March 3.

Arthur M. Wolfe, an American astrophysicist who for a decade directed the Center for Astrophysics and Space Sciences at the University of California, San Diego and achieved widespread recognition for his discoveries about star formation and the early universe, died on February 17 following a battle with cancer in La Jolla, Calif. He was 74.

Astronomers see huge clouds of gas orbiting supermassive black holes at the centers of galaxies. Once thought to be a relatively uniform, fog-like ring, the accreting matter instead forms clumps dense enough to intermittently dim the intense radiation blazing forth as these enormous objects condense and consume matter, they report in a paper to be published in the Monthly Notices of the Royal Astronomical Society, available online now.

Larry Smarr, a physicist whose work at the University of Illinois at Urbana-Champaign on calculating black hole collisions led him to champion a federal commitment to dramatically enhance U.S. computing power – which in turn led to the development of NCSA Mosaic, the precursor to web browsers – was named today as the first 2014 recipient of the Golden Goose Award, which goes to three or four winners annually.

George Fuller, an astrophysicist and professor of physics who directs UC San Diego’s Center for Astrophysics and Space Sciences, known as CASS, has been selected to receive the 2013 Hans A. Bethe Prize.

Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events.

Snaking cables and racks of computer processors with winking blue lights fill a room in University of California, San Diego’s Mayer Hall. It’s a powerful resource, made more so through links to a network of more than 80 similar centers distributed across the country.
