Many readers have written to tell us that researchers are examining the possibility of using Brownian ratchets to help combat the problem of heat dissipation in miniaturized electronics. "Currently, devices are engineered to operate near thermal equilibrium, in accordance with the Second Law of Thermodynamics which states that heat tends to transfer from a hotter unit to a cooler one. However, using the concept of Brownian ratchets, which are systems that convert non-equilibrium energy to do useful work, the researchers hope to allow computers to operate at low power levels, and harness power dissipated by other functions. 'The main quest we have is to see if by departing from near-equilibrium operation, we can perform computation more efficiently,' Ghosh told iTnews. 'We aren't breaking the Second Law — that's not what we are claiming,' he said. 'We are simply re-examining its implications, as much of the established understanding of power dissipation is based on near-equilibrium operation.'"

TaeKwonDood writes "All paper is made of cellulose, which at the nanoscale level is quite strong, but paper processing makes large, fragile fibers that break easily. Researchers in Sweden have have come up with a manufacturing process that keeps the fibers small, resulting in 'nanopaper' with over 1.6 times the tensile strength of cast iron (214 megapascals vs. 130 mPa). And since cellulose is the most abundant organic compound on the planet, it's cheap to use compared to other exotic, expensive-to-produce options — such as carbon nanotubes."

Stating the obvious: "Two scientists write that obese people are disproportionately responsible for high food prices and greenhouse gas emissions because they consume 18% more food energy due to their greater body mass -- and require increased quantities of fuel to transport themselves and the food they eat. 'Promotion of a normal distribution of BMI would reduce the global demand for, and thus the price of, food,' write the authors, Phil Edwards and Ian Roberts of the evocatively named London School of Hygiene & Tropical Medicine."

randomtimes writes "A row about who should pay for extra network costs incurred by the iPlayer has broken out between internet service providers (ISPs) and the BBC. ISPs say the on-demand TV service is putting strain on their networks, which need to be upgraded to cope. '"The iPlayer has come along and made downloading a legal and mass market activity," said Michael Phillips, from broadband comparison service broadbandchoices.co.uk. He said he believed ISPs were partly to blame for the bandwidth problems they now face. "They have priced themselves as cheaply as possible on the assumption that people were just going to use e-mail and do a bit of web surfing," he said. ISPs needed to stop using the term 'unlimited' to describe their services and make it clear that if people wanted to watch hours of downloaded video content they would have to pay a higher tariff, he added.'"

Lucas123 writes "Using mean time between failure rates suggest that disks can last from 1 million to 1.5 million hours, or 114 to 170 years, but study after study shows that those metrics are inaccurate for determining hard drive life. One study found that some disk drive replacement rates were greater than one in 10. This is nearly 15 times what vendors claim, and all of these studies show failure rates grow steadily with the age of the hardware. One former EMC employee turned consultant said, 'I don't think [disk array manufacturers are] going to be forthright with giving people that data because it would reduce the opportunity for them to add value by 'interpreting' the numbers.'"

StCredZero writes "Researchers at CMU are working on a Modular Snake Robot. A video from this site is up on YouTube. In addition to being able to traverse a wide variety of terrain, the robot can also climb poles, the inside of pipes and conduits, small grooves in walls, and probably more. It can also swim. Many robots can do one of those tasks. This one can do them all. That's quite an accomplishment. This has tremendous potential for the maintenance of fiber optic networks, pipelines, and plumbing in large buildings; and also as a spy device. (I wonder how loud it is?)"

wwrmn writes "There's a debate going on over at bugs.launchpad.net on whether it's the Ubuntu, BIOS, hard-drive manufacturer, or pick-any-player's fault, but Ubuntu (and perhaps any OS) may be dramatically shortening the life of your laptop's hard drive due to an aggressive power-saving feature / acpi bug / OS configuration. Regardless of where the fault lies or how it's fixed, you might want to take some actions now to try to prevent the damage."

Strudelkugel writes "The BBC is reporting that a Californian company has created software that can layer relevant recorded sounds over locations in Google Earth. The firm, Wild Sanctuary, has thousands of hours of recordings from all over the world. Company director Dr. Krause has spent over 40 years collecting sounds from natural and man-made habitats. '... his recordings include more than 15,000 animal noises, and sounds from a huge array of habitats, including cities, deserts, mountains and the marine environment. It is the largest library in existence of natural sound, he said. He said the idea would be to zoom-in on a particular area and then have the option to listen to the accompanying sound.'"

An anonymous reader noted that apparently Breakpoints have now been patented. From the link "A method for debugging including the steps of receiving code having a software breakpoint function therein, running the code for the purpose of debugging, monitoring the code to detect the presence of the software breakpoint function, recognizing the software breakpoint function, determining an action to be performed based on the software breakpoint function, and implementing the action. The present invention also includes an apparatus for implementing the method for debugging and a medium embodying a program of instructions for execution by a device to perform the method for debugging."
