writes: A study, by Massachusetts Institute of Technology, appearing in Proceedings of the National Academy of Sciences shows symptoms of mental retardation and autism have been reversed for the first time in laboratory mice.
The researchers, based at MIT's Picower Institute for Learning and Memory, targeted an enzyme called PAK which affects the number, size and shape of connection between brain cells. They found that inhibiting the enzyme stopped mice with Fragile X Syndrome behaving in erratic ways.
"This implies that future treatment may still be effective even after symptoms are already pronounced" according to Dr Susumu Tonegawa of the research group.Link to Original Source
writes: Sun Microsystems on revealed the Constellation System, a high-performance computing platform that company executives claim will vault the company back into the top ranks of supercomputer manufacturers. The linchpin in the system is the switch that conducts traffic between the servers, memory and data storage. Code-named Magnum, the switch comes with 3,456 ports, a larger-than-normal number that frees up data pathways inside these powerful computers.
"We are looking at a factor-of-three improvement over the current best system at an equal number of nodes," said Andy Bechtolsheim, chief architect and senior vice president of the systems group at Sun. "We have been somewhat absent in the supercomputer market in the last few years."
The Texas Advanced Computing Center (TACC) at the University of Texas is currently preparing a Constellation system. If TACC can get enough Barcelona chips from Advanced Microsystems by October 15, its will provide a peak performance of around 500 teraflops. A fully built-out Constellation system, with contemporary components, could hit a peak of 2 petaflops.
