Before 64-slice CT appeared on the scene, many physicians thought the future of cardiac scans belonged to a completely different technology: magnetic resonance imaging. Instead of X rays, MRI uses powerful electromagnets that are tuned to detect the hydrogen found in water--which in turn is present in most...
In a letter sent last month to NASA Administrator Michael Griffin, former astronaut Rusty Schweickart, B612's chairman, called attention to the Apophis dilemma. He urged that a radio transponder, similar to those on commercial airliners, be landed on the asteroid so that astronomers might track its orbit precisely to...
Compared with previous technologies, which suspended DNA fragments in gel and decoded them using electrophoresis, the new procedure attaches thousands of DNA fragments onto tiny one-micron beads. Four different-colored dyes bind at specific locations, depending on which of the four DNA bases is present, allowing scientists to scan...
The new procedure can be used to compare differences with a previously sequenced genome, making it useful to determine how the 0.1 percent genetic variation among humans is expressed. It cannot be used to sequence an entirely new genome.
Sinclair said that he and his fellow researchers are in the process of establishing the individual purpose of each gene in order to determine which ones can be used for medicines. They are currently using one of the genes in the Sir2 family to protect mice from brain disorders analogous...
