The Sub-Picosecond Pulse Source (SPPS) collaboration has published data from the first experiments ever using a linear accelerator-based femtosecond x-ray source, and has developed an important tool for ultra-fast science. SPPS makes the world's shortest bunches of electrons in the SLAC linear accelerator and turns them into very bright pulses of x-ray light one thousand times shorter than those made in synchrotron rings like SPEAR3.

The 2005 International Linear Collider Workshop kicked off March 18 by announcing the director for the newly formed Global Design Effort (GDE) for the proposed electron-positron collider.

According to the results from a Livermore computer model, some of the small change jingling in your pocket contains zinc and copper created in massive gamma-ray bursts (GRBs) that rank as the most impressive light shows in the universe.

High-temperature superconductors (HTSCs) operate in mysterious ways, but scientists are starting to understand their peculiarities by using a state-of-the-art spectroscopy system at SSRL.

Scientists have been able to follow the flow of excitation energy in both time and space in a molecular complex using a new technique called two-dimensional electronic spectroscopy. While holding great promise for a broad range of applications, this technique has already been used to make a surprise finding about the process of photosynthesis.

National security today requires broad and effective engagement in the international arena.

A detailed and extensive new analysis of the fossil records of marine animals over the past 542 million years has yielded a stunning surprise. Biodiversity appears to rise and fall in mysterious cycles of 62 million years for which science has no satisfactory explanation. The analysis, performed by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, has withstood thorough testing so that confidence in the results is above 99-percent.

As the sun rises each day, warming the grounds and buildings of SLAC, the entire SPEAR3 facility expands in response. The change is minuscule, on the scale of a few microns--far too slight to observe with the naked eye.

Livermore scientists are working to solve a 50-year-old question: Can neutrinos – a particle that is relatively massless, has no electric charge yet is fundamental to the make-up of the universe – transform from one type to another?

As the microbial world comes to light through DNA sequencing, the new Integrated Microbial Genomes (IMG) data management system of the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) will deliver valuable information for the benefit of the global research community.
