A red blood cell is tough and flexible because certain proteins in its
membrane link together. But linkage interferes with the cell's development
-- so the gene for the protein linker makes different forms, one that
links and one that doesn't. Researchers have found the
switch that controls this alternative splicing.
Here come
the T-rays
Berkeley Lab researchers recently helped produce "T-rays" at
the Thomas Jefferson National Accelerator Facility in Virginia -- beams
of radiation with trillion-cycles-per-second frequency, thousands of times
more powerful than T-rays from powerful lasers. Their success brings the
Advanced Light Source closer to building a new synchrotron ring for high-powered
T-ray beams.
Envisioning
the Grid
The winners of supercomputing's Bandwidth Challenge for three years in a
row are far from complacent about the future of remote scientific visualization
on the Grid. Focusing on the gulf between hype and performance, they are
tackling some of the
most important technical challenges facing the Grid visualization community.
