Speed-up may make “topic-sensitive” page rankings feasible Computer science researchers at Stanford University have developed several new techniques that together may make it possible to calculate Web page rankings as used in the Google search engine up to five times faster. The speed-ups to Google’s method may make it realistic to calculate page rankings personalized for an individual’s interests or customized to a particular topic. The Stanford team includes grad

Astronomers looking for planetary systems that resemble our own solar system have found the most similar formation so far. British astronomers, working with Australian and American colleagues, have discovered a planet like Jupiter in orbit round a nearby star that is very like our own Sun. Among the hundred found so far, this system is the one most similar to our Solar System. The planet’’s orbit is like that of Jupiter in our own Solar System, especially as it is nearly circular and there

By combining quantum computation and quantum interrogation, scientists at the University of Illinois at Urbana-Champaign have found an exotic way of determining an answer to an algorithm – without ever running the algorithm.

Using an optical-based quantum computer, a research team led by physicist Paul Kwiat has presented the first demonstration of “counterfactual computation,” inferring information about an answer, even though the computer did not run. The researchers report their

Did you ever arrange to meet a friend at a busy street corner, then rush up to a total stranger thinking it was your friend? Neuroscientists have a theory to explain why such potentially embarrassing mistakes occur. They probe the underlying perceptual and neural processes of visual search by studying how distracters affect performance of a visual search task. One might intuitively expect that as background noise created by distracters and errors increase, confidence in one’s decision plummets
