New Ship Will Remain Stable By Creating Its Own Inner Waves

Zothecula writes “When offshore oil drilling rigs are being installed, serviced or dismantled, the workers typically stay in cabins located on adjacent floating platforms. These semi-submersible platforms are towed into place (or travel under their own power) and then their hulls are partially filled with water, allowing them to remain somewhat stable in the pitching seas. Now, a ship is being built to serve the same purpose, but that will be a much more mobile alternative. It will keep from rolling with the waves by generating its own waves, inside its hull.” Read more of this story at Slashdot.

High-end CPU Coolers Reviewed and Compared

jjslash writes “CPU cooling units are an often-overlooked but always important side of PC building, whether you’re looking to overclock or you simply want a cool-running, silent system. It’s also easy to get lost if you aren’t an enthusiast who keeps tabs on the best options. TechSpot has rounded up 10 high-end CPU coolers (read: huge heatsinks) including top units from Noctua, Thermalright, Xigmatek, Silverstone and Thermaltake. If you’re willing to spend the cash, they rate the Noctua NH-U14S as the best overall pick. For a tighter budget, the Thermalright offerings provide the best bang for your buck.” Read more of this story at Slashdot.

Sleep Found To Replenish a Type of Brain Cell

New submitter wrackspurt writes “Sleep deprivation has long been thought to be prevalent in the industrialized world. A new study (abstract) explains one very good reason why at least seven hours of sleep a night is necessary. Quoting the BBC: ‘Sleep ramps up the production of cells that go on to make an insulating material known as myelin which protects our brain’s circuitry. … The increase was most marked during the type of sleep that is associated with dreaming – REM or rapid eye movement sleep — and was driven by genes. In contrast, the genes involved in cell death and stress responses were turned on when the mice were forced to stay awake.'” Read more of this story at Slashdot.

Facebook To Overhaul Data Use Policy

dryriver writes “The new Facebook advertising policy: ‘Our goal is to deliver advertising and other commercial or sponsored content that is valuable to our users and advertisers. In order to help us do that, you agree to the following: You give us permission to use your name, profile picture, content, and information in connection with commercial, sponsored, or related content (such as a brand you like) served or enhanced by us. This means, for example, that you permit a business or other entity to pay us to display your name and/or profile picture with your content or information, without any compensation to you. If you have selected a specific audience for your content or information, we will respect your choice when we use it.’ — Facebook also made it clear that the company can use photo recognition software to correctly identify people on the network. It said: ‘We are able to suggest that your friend tag you in a picture by scanning and comparing your friend’s pictures to information we’ve put together from your profile pictures and the other photos in which you’ve been tagged.’ — It [Facebook] said it was also clarifying that some of that information reveals details about the device itself such as an IP address, operating system or – surprisingly – a mobile phone number. The Register has asked Facebook to clarify this point as it’s not clear from the revised policy wording if a mobile number is scooped up without an individual’s knowledge or as a result of it being previously submitted by that person to access some of the company’s services. Importantly, Facebookers are not required to cough up their mobile phone number upon registering with the service. At time of writing, Facebook was yet to respond with comment.” Read more of this story at Slashdot.

These Satellite Images of Earth "Breathing" Are Freaking Me Out

It freaks me out that tiny atoms and huge solar systems consist of things rotating around each other in a similar way. It’s also weird to see time-lapse footage of human beings building things (like that super-fast hotel build in China) and realize how insectoid our activities look when sped up. And above you see the latest strange big/small connection: The planet Earth resembling a beating heart or a breathing being. A guy named John Nelson runs the UX Blog , which covers user experience, mapping and data visualization for parent software company IDV Solutions. Nelson pulled twelve rare, unobscured-by-clouds images of our planet off of NASA’s Visible Earth catalog taken at different times of the year. Stitching them together into an animation, he made the visually stunning discovery you see here: As the seasons change, the ebb and flow of snow and greenery makes our little rock look like it’s breathing.

The World’s First CPU Liquid Cooler Using Nanofluids

An anonymous reader writes “CPU water cooling may be more expensive than air cooling, but it is quieter and moves the bulk away from your CPU. It’s also improving, as Zalman has just demonstrated with the announcement of the Reserator 3. Zalman is claiming that the Reserator 3 is the world’s first liquid cooler to use nanofluids. What’s that then? It involves adding refrigerant nanoparticles to the fluid that gets pumped around inside the cooler transporting the heat produced by a CPU to the radiator and fan where it is expelled. By using the so-called nanofluid, Zalman believes it can offer better cooling, and rates the Reserator 3 as offering up to 400W of cooling while remaining very quiet. The fluid and pump is supplemented by a dual copper radiator design and “quadro cooling path, ” which consists of two copper pipes sitting behind the fan and surrounded by the radiators. The heatsink sitting on top of the CPU is a micro-fin copper base allowing very quick transfer of heat to the nanofluid above.” Read more of this story at Slashdot.

The Death of the American Drive-in

Hugh Pickens DOT Com writes “Claire Suddath writes in Businessweek that the number of drive-ins in America has dwindled from over 4, 000 in the 1960s to about 360 today. Since Hollywood distributors are expected to stop producing movies in traditional 35 millimeter film by the end of this year and switch entirely to digital, America’s last remaining drive-ins — the majority of which are still family-owned and seasonally operated — could soon be gone. ‘We have challenges that other movie theaters don’t, ‘ says John Vincent, president of United Drive-In Theater Owners Association and the owner of Wellfleet Drive-In in Cape Cod, Mass. ‘We have fewer screens and can only show one or two movies a night. Now we have to spend tens of thousands of dollars just to stay in business.’ According to Vincent, only 150 drive-ins have converted to digital so far — the other 210 have until the end of the year either to get with the program or go out of business. It may seem silly to fret over the fate of 210 movie theaters whose business model is outdated, even compared with regular movie theaters, but Honda Motor Co. is offering help with a program called ‘Project Drive-In.’ The car company is planning to give away five digital projectors by the end of the year. Winners will be determined by voting from the public, which can be done online through Sept. 9 at ProjectDriveIn.com. ‘Cars and drive-in theaters go hand in hand, ‘ says Alicia Jones, manager of Honda & Acura social marketing, ‘and it’s our mission to save this slice of Americana that holds such nostalgia for many of us.'” Read more of this story at Slashdot.

Effects of Parkinson’s-Disease Mutation Reversed In Cells

An anonymous reader sends this quote from a press release at Eurekalert: “UC San Francisco scientists working in the lab used a chemical found in an anti-wrinkle cream to prevent the death of nerve cells damaged by mutations that cause an inherited form of Parkinson’s disease. A similar approach might ward off cell death in the brains of people afflicted with Parkinson’s disease, the team suggested in a study reported online in the journal Cell on August 15 (abstract). … Mutations that cause malfunction of the targeted enzyme, PINK1, are directly responsible for some cases of early-onset Parkinson’s disease. Loss of PINK1 activity is harmful to the cell’s power plants, called mitochondria, best known for converting food energy into another form of chemical energy used by cells, the molecule ATP. In Parkinson’s disease, poorly performing mitochondria have been associated with the death of dopamine-producing nerve cells in a region of the brain called the substantia nigra, which plays a major role in control of movement. Loss of these cells is a hallmark of Parkinson’s disease and the cause of prominent symptoms including rigidity and tremor. A UCSF team led by Shokat, a Howard Hughes Medical Institute Investigator, used the chemical, called kinetin, to increase mutant PINK1 enzyme activity in nerve cells to near normal levels. ‘In light of the fact that mutations in PINK1 produce Parkinson’s disease in humans, the finding that kinetin can speed mutated PINK1 activity to near normal levels raises the possibility that kinetin may be used to treat these patients, ‘ Shokat said.” Read more of this story at Slashdot.

Xerox Confirms To David Kriesel Number Mangling Occuring On Factory Settings

An anonymous reader writes with a followup to last week’s report that certain Xerox scanners and copiers could alter numbers as they scanned documents: “In the second Xerox press statement, Rick Dastin, Vice President at Xerox Corporation, stated: ‘You will not see a character substitution issue when scanning with the factory default settings.’ In contrast, David Kriesel, who brought up the issue in the first place, was able to replicate the issue with the very same factory settings. This might be a serious problem now. Not only does the problem occur using default settings and everyone may be affected, additionally, their press statements may have misled customers. Xerox replicated the issue by following Kriesel’s instructions, later confirming it to Kriesel. Whole image segments seem to be copied around the scanned data. There is also a new Xerox statement out now.” Swapping numbers while copying may seem like bizarre behavior for a copier, but In comments on the previous posting, several readers pointed out that Xerox was aware of the problem, and acknowledged it in the machine’s documentation; the software updates promised should be welcome news to anyone who expectes a copier to faithfully reproduce important numbers.
