HughPickens.com writes: Ever notice at your high school reunions how some classmates look ten years older than everybody else — and some look ten years younger. Now BBC reports that a study of people born within a year of each other has uncovered a huge gulf in the speed at which human bodies bodies age. The report tracked traits such as weight, kidney function and gum health and found that some of the 38-year-olds in the study were aging so badly that their "biological age" was on the cusp of retirement. "They look rough, they look lacking in vitality," says Prof Terrie Moffitt. The study says some people had almost stopped aging during the period of the study, while others were gaining nearly three years of biological age for every twelve months that passed. "Any area of life where we currently use chronological age is faulty, if we knew more about biological age we could be more fair and egalitarian," says Moffitt. The researchers studied aging in 954 young humans, the Dunedin Study birth cohort, tracking multiple biomarkers across three time points spanning their third and fourth decades of life. They developed and validated two methods by which aging can be measured in young adults, one cross-sectional and one longitudinal. According to Moffit the science of healthspan extension may be focused on the wrong end of the lifespan; rather than only studying old humans, geroscience should also study the young. "Eventually if we really want to slow the process of ageing to prevent the onset of disease we're going to have to intervene with young people."
itwbennett writes: Back in May, former Goldman Sachs programmer Sergey Aleynikov was convicted by a jury for stealing 32MB of code for Goldman's high-frequency trading system, code that Aleynikov maintained he copied for intellectual pursuits and was, in fact, open-source. On Monday, Judge Daniel P. Conviser of New York's State Supreme Court dismissed the conviction, saying that Aleynikov acted wrongfully by taking the code, but his actions did not meet the standard under the law in which he was charged. "The evidence did not prove he intended to appropriate all or a major portion of the code's economic value," Conviser wrote.

At the time, I was a junior at Yale and the only person at the table studying a computer-related major. We went around saying what our big dreams were. When I said that I'm studying computer science because I want to be a software engineer and hope to start my own company one day, he said, 'Why waste so many years learning how to code? Why not just pay someone else to build your idea?'" But Rhee isn't buying into the idea of the look-Ma-no-tech-skills "idea person." "We must not neglect the merits of technical skills in the conception of the 'idea person,'" she argues. "What the 60-year old entrepreneur and others of his generation — the people in control of the education we receive — don't realize is this: for college students dreaming of becoming unicorns in Silicon Valley, being an 'idea person' is not liberating at all. Being able to design and develop is liberating because that lets you make stuff. This should be a part of what we see in the 'idea person' today and what it means to be 'right' when designing an undergraduate curriculum."
jez9999 writes: I'm a software developer in the UK, and I've found that it's very rare (maybe 5% of the time) to find an employer that will even consider any working from home, let alone for the majority of the time. I see it as a win-win; you're able to work in the home environment you are most productive in, and you can use the time you would've been commuting to work a bit longer for the employer. Not only that, but you're not adding to road congestion either. Skype, etc. make communication with coworkers a snap these days. So how do you go about finding homeworking jobs? Is it better to demand it from the get-go, or wait a few months and then ask for it? Is it more common than 5% of jobs in the US (in which case I guess it's a cultural thing the UK needs to catch up with)?

Dave Camp, Firefox's director of engineering, sent out two lengthy emails, just three minutes apart: Three Pillars and Revisiting how we build Firefox. Both offer a lot more detail into what Mozilla is hoping to achieve.
ErnieKey writes: The 3D printed extreme reduction gearing device, created by long-time puzzle maker M. Oskar van Deventer, may leave you puzzled for its obvious applications, but the coaxial cranking mechanism offers potential in a variety of real-world applications with multi-colored gears that move in opposite directions at a ratio of 11,373,076 : 1. This 3D printed reduction gearing device is compact and multi-colored, and looks deceivingly simple at first glance. Developed through a complex algorithm, it could possibly offer potential as parts for machines like 3D printers, aerospace and automotive components, as well as perhaps robotics and a variety of motors.

Lauren Weinstein writes: A couple of months ago, in "Seeking Anecdotes Regarding 'Older' Persons' Use of Web Services," I asked for stories and comments regarding experiences that older users have had with modern Web systems, with an emphasis on possible problems and frustrations. I purposely did not define "older" — with the result that responses arrived from users (or regarding users) self-identifying as ages ranging from their 30s to well into their 90s (suggesting that "older" is largely a point of view rather than an absolute). Before I began the survey I had some preconceived notions of how the results would appear. Some of these were proven correct, but overall the responses also contained many surprises, often both depressing and tragic in scope. The frustration of caregivers in these contexts was palpable. They'd teach an older user how to use a key service like Web-based mail to communicate with their loved ones, only to discover that a sudden UI change caused them to give up in frustration and not want to try again. When the caregiver isn't local the situation is even worse. While remote access software has proven a great boon in such situations, they're often too complex for the user to set up or fix by themselves when something goes wrong, remaining cut off until the caregiver is back in their physical presence.
coondoggie writes: A prototype wave energy device advanced with backing from the Energy Department and U.S. Navy has passed its first grid-connected open-sea pilot testing. According to the DOE, the device, called Azura, was recently launched and installed in a 30-meter test berth at the Navy's Wave Energy Test Site (WETS) in Kaneohe Bay, on the island of Oahu, Hawaii. This pilot testing is now giving U.S. researchers the opportunity to evaluate the long-term performance of the nation’s first grid-connected 20-kilowatt wave energy converter (WEC) device to be independently tested by a third party—the University of Hawaii—in the open ocean, the DOE said.
1sockchuck writes: A new supercomputing cluster immersed in tanks of dielectric fluid has posted extreme efficiency ratings. The Vienna Scientific Cluster 3 combines several efficiency techniques to create a system that is stingy in its use of power, cooling and water. VSC3 recorded a PUE (Power Usage Efficiency) of 1.02, putting it in the realm of data centers run by Google and Facebook. The system avoids the use of chiillers and air handlers, and doesn't require any water to cool the fluid in the cooling tanks. Limiting use of water is a growing priority for data center operators, as cooling towers can use large volumes of water resources. The VSC3 system packs 600 teraflops of computing power into 1,000 square feet of floor space.
Kristine Lofgren writes: With arable land dwindling and the cost — both economically and environmentally — of growing and transporting food increasing, it's time to redefine farming. So Philips is creating a revolution with their new GrowWise indoor farm, which uses customized 'light recipes' in high-tech cells to grow plants that don't need pesticides or chlorine washes, and use a fraction of the water that traditional farming requires. The system can churn out 900 pots of basil a year in just one square meter of floor space, and bees keep things humming year-round for farming that is truly local, even in the middle of a city.
Lemeowski writes: It's not often that you get to glimpse behind the curtain and see what led a proprietary software company to open source its software. Last year, the networking software company Midokura made a strategic decision to open source its network virtualization platform MidoNet, to address fragmentation in the networking industry. In this interview, Midokura CEO and CTO Dan Mihai Dumitriu explains the company's decision to give away fours years of engineering to the open source community, how it changed the way its engineers worked, and the lessons learned along the way. Among the challenges was helping engineers overcome the culture change of broadcasting their work to a broader community.
LeadSongDog writes: The Royal Astronomical Society reports five supermassive black holes (SMBHs) that were previously hidden by dust and gas have been uncovered. The discovery suggests there may be millions more supermassive black holes in the universe than were previously thought. George Lansbury, a postgraduate student in the Centre for Extragalactic Astronomy, at Durham University, said: “For a long time we have known about supermassive black holes that are not obscured by dust and gas, but we suspected that many more were hidden from our view. Thanks to NuSTAR for the first time we have been able to clearly see these hidden monsters that are predicted to be there, but have previously been elusive because of their ‘buried’ state. Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole Universe then the predicted numbers are huge and in agreement with what we would expect to see.”

The statement reads in part: "We screwed up. Not just on July 2, but also over the past several years. We haven't communicated well, and we have surprised moderators and the community with big changes. We have apologized and made promises to you, the moderators and the community, over many years, but time and again, we haven't delivered on them. When you've had feedback or requests, we haven't always been responsive. The mods and the community have lost trust in me and in us, the administrators of reddit. Today, we acknowledge this long history of mistakes. We are grateful for all you do for reddit, and the buck stops with me."
malachiorion writes: The DARPA Robotics Challenge, the biggest and most well-funded international robotics competition in years, was a failure. After years of grueling work on the part of brilliant roboticists around the world, and millions in funding from the Pentagon, the finals came and went with little to no coverage from the mainstream media. The only takeaway, for those who aren't extremely dialed into robotics, is that a ton of robots fell down in funny ways. There were winners, but considering how downgraded the tasks were, compared to the ones initially announced in 2012, it was closer to the first DARPA Grand Challenge, where none of the robot cars finished, than the Urban Challenge, which kicked off the race to build deployable driverless cars. So just as DARPA regrouped after that first fizzle of a race, here's my argument for Popular Science: It's time to do it again, and make falling, and getting up, mandatory.
