That’s a lot of power potential from microscopic cyanobacteria (blue-green algae) that capture sunlight and then do a variety of biochemical processes. One potential process, the clean production of ethanol, is a high priority for DOE. Himadri Pakrasi, Ph.D., Washington University Professor of Biology in Arts & Sciences, and Professor of Energy in the School of Engineering and Applied Science, will head a team of biologists at Washington University and elsewhere in the analysis of the genomes of six related strains of Cyanothece bacteria.

Now, a St. Louis-area teenage boy and a computer game have gone hands-off, thanks to a unique experiment conducted by a team of neurosurgeons, neurologists, and engineers at Washington University in St. Louis. The boy, a 14-year-old who suffers from epilepsy, is the first teenager to play a two-dimensional video game, Space Invaders, using only the signals from his brain to make movements. More…

Jonathan S. Turner, Ph.D., was named the Barbara J. and Jerome R. Cox, Jr. Professor of Computer Science in the School of Engineering and Applied Science. The professorship was established by Jerome Cox, Sc.D., and his wife, Barbara, to advance the relationship between theory and practice in the design of digital systems. Jerome Cox is a senior faculty member and a former chair in the same department.

In the Thoroughman laboratory, volunteers play games on a computer screeen using a robotic arm so that Thoroughman and his colleagues can study how people learn motor skills.Central to being human is the ability to adapt: We learn from our mistakes. Previous theories of learning have assumed that the size of learning naturally scales with the size of the mistake. But now biomedical engineers at Washington University in St. Louis have shown that people can use alternative strategies: Learning does not necessarily scale proportionally with error.

These before (left) and after images show the effects of fumagillin-laden nanoparticles in a rabbit aorta.In laboratory tests, one very low dose of a drug was enough to show an effect on notoriously tenacious artery-clogging plaques. But it wasn’t so much the drug itself as how it was delivered. Fumagillin — a drug that can inhibit the growth of new blood vessels that feed atherosclerotic plaques — was sent directly to the base of plaques by microscopically small spheres called nanoparticles.

The answer to a 50-year-old question has been found by scientists at the School of Medicine. The question: Is it possible to accurately measure the intrinsic filling function of the heart?
