Csiko writes "Researchers at Boston University's department of cognitive and neural systems are working on an artificial brain implemented with memristors. 'A memristor is a two-terminal device whose resistance changes depending on the amount, direction, and duration of voltage that's applied to it. But here's the really interesting thing about a memristor: Whatever its past state, or resistance, it freezes that state until another voltage is applied to change it. Maintaining that state requires no power.' Also theoretically described, solid state versions of memristors have not been implemented until recently. Now researchers in Boston claim that memristors are the new key technology to implement highly integrated, powerful artificial brains on cheap and widely available hardware within five years."

future.nerd tips news that Wolfram Alpha is set to be launched tonight at 8PM EST (00:00 GMT), and the entire process will be broadcast live, via webcast. Steven Wolfram said to PCPro, "We've been rather surprised that we haven't been able to find even a single publicly available record of the commissioning of any large website at all. So we thought we would document our own experience. We can't guarantee that everything will go smoothly. We fully expect to encounter unanticipated situations along the way. We hope that it'll be interesting for people to join us as we work through these in real time." In a related blog post, he explains how Wolfram Alpha interacts with Mathematica.
