National Science Foundation (Arlington, Va., June 23) -- Aleksei Aksimentiev, a U. of I. professor of physics, used the National Science Foundation-supported Stampede supercomputer to explore a cutting-edge method of DNA sequencing. The method uses an electric field to drive a strand of DNA through a small hole, or “nanopore,” either in silicon or a biological membrane. Also: Red Orbit.com (Dallas, June 25).
