] DeMarse experimental "brain" interacts with an F-22 ] fighter jet flight simulator through a specially designed ] plate called a multi-electrode array and a common desktop ] computer. ] ] "It's essentially a dish with 60 electrodes arranged in a ] grid at the bottom," DeMarse said. "Over that we put the ] living cortical neurons from rats, which rapidly begin to ] reconnect themselves, forming a living neural network ] - a brain." ] ] The brain and the simulator establish a two-way ] connection, similar to how neurons receive and interpret ] signals from each other to control our bodies. Rat Brain cells in a silicon matrix can fly an airplane simulator. Seriously. What is the line between man and machine. What is the difference between a robot, a work animal, and a slave. These questions may eventually move out of the realm of science fiction. 'Brain' In A Dish Acts As Autopilot, Living Computer |

] A new means of propelling spacecraft being developed at ] the University of Washington could dramatically cut the ] time needed for astronauts to travel to and from Mars and ] could make humans a permanent fixture in space. ] ] In fact, with magnetized-beam plasma propulsion, or ] mag-beam, quick trips to distant parts of the solar ] system could become routine, said Robert Winglee, a UW ] Earth and space sciences professor who is leading the ] project.

Not quite a live stream, but it does have images that are updated every 5 minutes. According to the webpage, this USGS cam is the closest-operating camera to the volcano, which means about 4 miles away. There was a closer one at the Johnston Ridge Observatory, but since the Level III alert went out earlier today, that facility has been evacuated. Mount St. Helens VolcanoCam |

Terror attacks influence driving behavior in Israel |

Terror attacks in Israel produce a temporary lull in light accidents followed by a 35% spike in fatal accidents on Israeli roads 3 days after the attack. Our results are based on time-series analysis of Israeli traffic flows, accidents, and terror attacks from January 2001 through June 2002. Whereas prior studies have focused on subjective reports of posttraumatic stress, our study shows a population-level behavioral response to violent terror attacks.
