The right gene for the job
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 |
