Brain Needs to Remember Faces in Three Dimensions

ScienceDaily (Sep. 9, 2010) — In our dynamic 3-D world, we can encounter a familiar face from any angle and still recognize that face with ease, even if the person has, for example, changed his hair style. This is because our brain has used the 2-D snapshots perceived by our eyes (like a camera) to build and store a 3-D mental representation of the face, which is resilient to such changes.

An anonymous reader found a story that starts"We have developed algorithms that allow a robot to determine whether it should deceive a human or other intelligent machine and we have designed techniques that help the robot select the best deceptive strategy to reduce its chance of being discovered," said Ronald Arkin, a Regents professor in the Georgia Tech School of Interactive Computing."

Rackspace Shuts Down Quran-Burning Church's Sites

theodp writes"In response to a complaint, Rackspace has shut down the websites of the Dove World Outreach Center, a small 50-member church which has received national and international criticism for a planned book burning of the Quran on the anniversary of the 9-11 attacks. The center 'violated the hate-speech provision of our acceptable-use policy,' explained Rackspace spokesman Dan Goodgame. 'This is not a constitutional issue. This is a contract issue,' said Goodgame, who added he did not know how long it had hosted the church's sites. Not quite the same thing, but would Kurt Westergaard's cartoons of the Prophet Muhammad also violate Rackspace's AUP? How about Christopher Hitchens' Slate articles? Could articles from one-time Rackspace poster child The Onion pass muster?"

bonch writes"A new study on Greenland's and West Antarctica's rate of ice loss halves the estimate of ice loss. Published in the journal Nature Geoscience, the study takes into account a rebounding of the Earth's crust called glacial isostatic adjustment, a continuing rise of the crust after being smashed under the weight of the Ice Age. 'We have concluded that the Greenland and West Antarctica ice caps are melting at approximately half the speed originally predicted,' said researcher Bert Vermeeersen."

Here's an interesting and funny look at 526,000 OkCupid users, divided into groups by race and gender and all the the things each groups says it likes or is interested in. While it is far from being definitive, the groupings give a glimpse of what makes each culture unique. According to the results white men like nothing better than Tom Clancy, Van Halen, and golfing.

Scientists Create New Process to 'Program' Cancer Cell Death

ScienceDaily (Sep. 6, 2010) — Researchers at the California Institute of Technology (Caltech) have engineered a fundamentally new approach to killing cancer cells. The process -- developed by Niles Pierce, associate professor of applied and computational mathematics and bioengineering at Caltech, and his colleagues -- uses small RNA molecules that can be programmed to attack only specific cancer cells; then, by changing shape, those molecules cause the cancer cells to self-destruct.
