m now, if the technology proves successful? They w ould be the sorts of tasks that humans find effort less and that computers struggle with — the patter n recognition of seeing and identifying someone, w alking down a crowded sidewalk without running int o people, learning from experience. Specifically, the scientists say, the applications might include robots that can navigate a battlefield environmen t and be trained; low-power prosthetic devices tha t would allow blind people to see; and computerize d health-care monitors that watch over people in n ursing homes and send alerts to human workers if a resident’s behavior suggests illness. It is an appealing vision, but there are formidabl e obstacles. The prototype chip has 256 neuron-lik e nodes, surrounded by more than 262,000 synaptic memory modules. That is impressive, until one cons iders that the human brain is estimated to house u p to 100 billion neurons. In the Almaden research lab, a computer running the chip has learned to pl ay the primitive video game Pong, correctly moving an on-screen paddle to hit a bouncing cursor. It can also recognize numbers 1 through 10 written by a person on a digital pad — most of the time. But the project still has a long way to go. It is still questionable whether the scientists ca n successfully assemble large clusters of neuromor phic chips. And though the intention is for the ma chines to evolve more from learning than from bein g programmed, the software that performs that magi c for any kind of complex task has yet to be writt en. The project’s Pentagon sponsor is encouraged. “I’m surprised that we’re so far along, and I don’t se e any fundamental reason why it can’t be done,” sa id Todd Hylton, a program manager. If it succeeds, the project would seem to make pea ce with the “airplanes don’t flap their wings” cri
tique. “Yes, they are different, but bird wings an d plane wings both depend on the same aerodynamic principles to get lift,” said Christopher T. Kello , director of the Cognitive Mechanics Lab at the U niversity of California, Merced. “It’s the same wi th this project. You can use essential design elem ents from biology.” ~~~~~~~~~ <strong>NYT</strong>-1207 Japan Split on Hope for Vast Radiation Cleanup ... By M<strong>ART</strong>IN FACKLER Japan hopes the cleanup near the tsunami-ravaged F ukushima Daiichi nuclear plant will allow the disp laced to return home. ===== notyet (2 pages) FUTABA, Japan — Futaba is a modern-day ghost town — not a boomtown gone bust, not even entirely a vi ctim of the devastating earthquake and tsunami tha t leveled other parts of Japan’s northeast coast. Its traditional wooden homes have begun to sag and collapse since they were abandoned in March by re sidents fleeing the nuclear plant on the edge of t own that began spiraling toward disaster. Roofs po ssibly damaged by the earth’s shaking have let rai n seep in, starting the rot that is eating at the houses from the inside. The roadway arch at the entrance to the empty town almost seems a taunt. It reads: “Nuclear energy: a correct understanding brings a p rosperous lifestyle.” Those who fled Futaba are among the nearly 90,000 people evacuated from a 12-mile zone around the Fu kushima Daiichi plant and another area to the nort hwest contaminated when a plume from the plant sca ttered radioactive cesium and iodine.
