Aristo, the Washington University robot, uses sensor networks to avoid simulated “fire” – red cups – while navigating near “safe” areas,which are blue cups.Agent 007 is a mighty versatile fellow, but he would have to take backseat to agents being trained at Washington University in St. Louis. Computer scientist engineers here are using wireless sensor networks that employ software agents that so far have been able to navigate a robot safely through a simulated fire and spot a simulated fire by seeking out heat. Once the agent locates the fire, it clones itself – try that, James Bond — creating a ring of software around the fire. A “fireman” can then communicate with this multifaceted agent through a personal digital assistant (PDA) and learn where the fire is and how intense it is. Should the fire expand, the agents clone again and maintain the ring – an entirely different “ring of fire.” More…

Endothelial cells normally line blood vessels and actively protect against blood clotting. Blood clotting on artificial materials is currently so severe that the use of vascular grafts is limited to large diameter vessels. A team led by Donald Elbert, Ph. D., Washington University assistant professor of biomedical engineering, synthesized the new materials. More…

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.
