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.

Jamie is helping bring our childhood fantasies/nightmares to life with a link that says"Andrei Rhode, a researcher involved with the project, said that existing optical tweezers are able to move particles the size of a bacterium a few millimeters in a liquid. Their new technique can move objects one hundred times that size over a distance of a meter or more."
Personality Predicts Cheating More Than Academic Struggles, Study Shows
ScienceDaily (Sep. 7, 2010) — Students who cheat in high school and college are highly likely to fit the profile for subclinical psychopathy -- a personality disorder defined by erratic lifestyle, manipulation, callousness and antisocial tendencies, according to research published by the American Psychological Association. These problematic students cheat because they feel entitled and disregard morality, the study found.

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.

Short Nighttime Sleep Duration Among Infants, Young Children Associated With Obesity in Later Life
ScienceDaily (Sep. 6, 2010) — Insufficient amounts of nighttime sleep among infants and preschool-aged children may be a significant risk factor for developing childhood obesity, according to a report in the September issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals. Additionally, napping does not appear to be an adequate substitute for nighttime sleep in terms of preventing obesity.

Older Adults Experience “destination Amnesia” And Over-Confidence With False Beliefs
ScienceDaily (Aug. 30, 2010) — I'm sure I told you that already! Older adults are more likely to have destination memory failures -- forgetting who they've shared or not shared information with, according to a new study led by Baycrest's Rotman Research Institute.
Building Prisons Without Walls Using GPS Devices
Hugh Pickens writes"Graeme Wood writes in the Atlantic that increasingly GPS devices are looking like an appealing alternative to conventional incarceration, as it becomes ever clearer that traditional prison has become more or less synonymous with failed prison. 'By almost any metric, our practice of locking large numbers of people behind bars has proved at best ineffective and at worst a national disgrace,' writes Wood. But new devices such as ExacuTrack suggest a revolutionary possibility: that we might do away with the current, expensive array of guards and cells and fences, in favor of a regimen of close, constant surveillance on the outside and swift, certain punishment for any deviations from an established, legally unobjectionable routine. 'The potential upside is enormous. Not only might such a system save billions of dollars annually, it could theoretically produce far better outcomes, training convicts to become law-abiders rather than more-ruthless lawbreakers,' adds Wood. 'The ultimate result could be lower crime rates, at a reduced cost, and with considerably less inhumanity in the bargain.'"

Tech's Dark Secret, It's All About Age
theodp writes"Universities really should tell engineering students what to expect in the long term and how to manage their technical careers. Citing ex-Microsoft CTO David Vaskevitch's belief that younger workers have more energy and are sometimes more creative, Wadwha warns that reports of ageism's death have been greatly exaggerated. While encouraging managers to consider the value of the experience older techies bring, Wadwha also offers some get-real advice to those whose hair is beginning to grey: 1) Move up the ladder into management, architecture, or design; switch to sales or product management; jump ship and become an entrepreneur. 2) If you're going to stay in programming, realize that the deck is stacked against you, so be prepared to earn less as you gain experience. 3) Keep your skills current — to be coding for a living when you're 50, you'll need to be able to out-code the new kids on the block. Wadwha's piece strikes a chord with 50-something Dave Winer, who calls the rampant ageism 'really f***ed up,' adding that, 'It's probably the reason why we keep going around in the same loops over and over, because we chuck our experience, wholesale, every ten years or so.'"

It's Official — AMD Will Retire the ATI Brand
J. Dzhugashvili writes"A little over four years have passed since AMD purchased ATI. In May of last year, AMD took the remains of the Canadian graphics company and melded theminto a monolithic products group, which combined processors, graphics, and platforms. Now, AMD is about to take the next step: kill the ATI brand altogether. The company has officially announced the move, saying it plans to label its next generation of graphics cards 'AMD Radeon' and 'AMD FirePro,' with new logos to match. The move has a lot to do with the incoming arrival of products like Ontario and Llano, which will combine AMD processing and graphics in single slabs of silicon."
