OK, this doesn't have anything to do with law libraries, but guess what, Cal Tech has announced that the Caltech Nose Team (and wouldn't you love to get one of their team uniforms) has a working model of an electronic nose. According to the article "The Caltech Nose has shown the ability to function well in normal room temperatures and varied setting. It can detect an odor and then by robotics turn its attention to the odor or vapor it identifies as a concern." I expect librarians can think of ways this might be useful to us. :-)
And another thing: Another report that scientists at the University of California, Santa Cruz (UCSC) have developed an electronic chip that is a step towards the design of retinal prostheses that will come close to mimicking human vision.
