A USC Information Sciences Institute researcher thinks she has found a new source of artificial intelligence computing power to solve difficult IT problems of information classification, reliability, and meaning. That tool, according to ISI computer scientist Kristina Lerman, is people, human intelligence at work on the social web, the network of blogs, bookmark, photo and video- sharing sites, and other meeting places now involving hundreds of thousands of individuals daily, recording observations and sharing opinions and information.
Evolution is not just about human origins, dinosaurs and fossils, says Binghamton University evolutionist David Sloan Wilson. It can also be applied to almost every aspect of human life, as he demonstrates in his first book for a general audience, Evolution for Everyone: How Darwin’s Theory Can Change the Way We Think About Our Lives (Bantam Press 2007). Using witty, straightforward language and compelling anecdotes, Wilson outlines the basic principles of evolution in a way that can be easily understood by non-experts. He then uses the principles to explain phenomena as diverse as why beetles commit infanticide, why dogs have curly tails, and why people laugh and make art.
