    Since assuming my new role at SLAC, I’ve spoken several times about what the concept of “one lab” means to me. It’s about breaking down the silos that separate our scientific areas and making sure we have a collective understanding of the amazing science that is taking place here. This week was a great example of the breadth of science at SLAC.

    The first controlled studies of extremely hot, dense matter have overthrown the widely accepted 50-year-old model used to explain how ions influence each other’s behavior in a dense plasma. The results should benefit a wide range of fields, from research aimed at tapping nuclear fusion as an energy source to understanding the inner workings of stars.

In high harmonic generation (HHG), an ultrashort laser pulse is focused into a gas, boosting electrons to higher energies and freeing them from their parent atoms. The electrons then recombine or collide with their parent atoms, releasing surplus energy as a broad spectrum of light, which can include ultraviolet and X-ray frequencies.

    Einstein's famous equation E=mc2 is often displayed with an ominous mushroom cloud behind it, pointing out the perils of the vast amounts of energy that can be released from the mass of an atomic bomb. But reverse the equation, and you'll see that matter can not only be converted to energy, energy can be converted to matter.

    A neutrino telescope encased in ice has cast doubt on one of the leading theories on the origin of ultra-high-energy cosmic rays. The neutrino telescope, known as IceCube, looked for high-energy neutrinos that would likely be produced if the violent extragalactic explosions known as gamma-ray bursts (GRBs) are the source of such powerful cosmic rays.

But, as reported in a paper soon to appear in The Astrophysical Journal, most of the gamma rays detected by the LAT cannot be attributed to individual point sources.

    Image - Representation of an atom

    When most of us think of an atom, we think of tiny electrons whizzing around a stationary, dense nucleus composed of protons and neutrons, collectively known as nucleons. A collaboration between the U.S. Department of Energy’s Argonne and Thomas Jefferson National Laboratories has demonstrated just how different reality is from our simple picture, showing that a quarter of the nucleons in a dense nucleus exceed 25 percent of the speed of light, turning the picture of a static nucleus on its head.

Lasers may produce light waves that are not precisely coherent in space: the beam widens as it travels. Some produce light waves that are not precisely coherent in time: the waves are of slightly different frequencies, and while they travel close together their troughs and crests do not precisely match.

    Abner "Abi" Soffer, physics coordinator for the BaBar collaboration, has been working with quarks in one form or another since his grad-student days at Cornell University. He joined SLAC’s BaBar experiment in 1998 as a post-doctoral researcher with Colorado State University, and he's been with BaBar ever since – most recently in a role that requires him to commute back and forth to Israel, 27 hours door to door each way, every two weeks.

    Tucked behind the control area for Beamline 9-2 at the Stanford Synchrotron Radiation Lightsource, between an elevator and an old metal cabinet, is a plaque. The inscription reads, "The Sixth Addition to the House that Axel Built – 1994." Below that, four coins – a dime and three pennies – are set into the plaque's dark surface.
