A new focus for the mechanism of nerve growth

... assembled at the leading edge and moved rearward, powered by a myosin II motor located at its back end. But, the networks making up this actin treadmill are constantly being recycled at the back end, and actin molecules are freed to complete a "virtual belt" cycle and be used again. "Surprisingly, growth ...

Georgia Tech accelerates drug discovery with new IBM supercomputing cluster

... 1350 system built on IBM BladeCenter® systems and powered by dual-core AMD Opteron TM processors is capable of performing more than 8.5 trillion calculations per second, which would place it as the world's 41st most powerful supercomputer based upon the November 2005 TOP500 list (www.top500.org) of superco...
