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 It may seem silly to fret over the fate of 210 movie theaters whose business model is outdated, even compared with regular movie theaters, but Honda Motor Co. is offering help with a program called ‘Project Drive-In.’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.

Studying the Slow Decay of a Laptop Battery For an Entire Year

First time accepted submitter jradavenport writes “I’ve been keeping a log of the health of my MacBook Air battery for the past year, taking samples every minute I use the computer (152, 411 readings so far!). This has allowed me to study both my own computing/work habits, but also the fascinating rapid decay of battery capacity. Comparing it to my previous 2009 MacBook Pro, the battery in this 2012 Air is degrading much faster.” Read more of this story at Slashdot.

Behind the Story of the iPhone’s Default Text Tone

An anonymous reader writes “In a fascinating post from Kelly Jacklin, the long time Apple software engineer details how he helped create the default text alert sound on the iPhone — a sound otherwise known as ‘Tri-tone.’ The history of the the pleasant text alert sound that we’ve all come to know and love stretches all the way back to 1998, nearly 10 years before the iPhone ever hit store shelves.” Here’s Jacklin’s post.

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.

Australian State Bans IBM From All Contracts After Payroll Bungle

renai42 writes “If you don’t follow Australian technology news, you’re probably not aware that over the past few years, the State of Queensland massively bungled a payroll systems upgrade in its Department of Health. The issues resulted in thousands of hospital staff being underpaid or not paid at all, and has ballooned in cost from under $10 million in budget to a projected total cost of $1.2 billion. Queensland has now banned the project’s prime contractor, IBM, comprehensively from signing any new contracts with any government department, until it addresses what the state says are IBM’s project governance issues.” Read more of this story at Slashdot.

China Has a Massive Windows XP Problem

An anonymous reader writes “The Chinese are going to have a very, very hard time kicking the Windows XP habit. The deadline for the retirement of Microsoft’s most successful operating system ever is eight months from tomorrow: April 8, 2014. That’s the day when the Redmond, Wash. company is to deliver the last XP security update. According to analytics company Net Applications, 37.2% of the globe’s personal computers ran Windows XP last month. If Microsoft’s estimate of 1.4 billion Windows PCs worldwide is accurate, XP’s share translates into nearly 570 million machines. In the U.S., 16.4% of all personal computers ran Windows XP in July, or about one in six, Net Applications’ data showed. But in China, 72.1% of the country’s computers relied on the soon-to-retire operating system last month, or nearly three out of every four systems.” Read more of this story at Slashdot.

Researchers Unveil Genome of ‘Immortal’ Cell Line Derived From Cancer Victim

vinces99 writes “Scientists have unveiled a comprehensive portrait of the genome of the world’s first immortal cell line, known as HeLa, derived in 1951 from an aggressive cervical cancer that killed Henrietta Lacks, a 31-year-old African-American woman. The cells, taken without her or her family’s knowledge, were pivotal in developing the polio vaccine, in vitro fertilization and cloning, and were the subject of a 2010 New York Times best-seller ‘The Immortal Life of Henrietta Lacks.’ The Lacks family has never been compensated and, until this new University of Washington study, has never had a say in how the information is used. The study, published Aug. 8 in Nature, pieced together the complicated insertion of the human papillomavirus genome, which contains its own set of cancer genes, into Lacks’ genome near an ‘oncogene, ‘ a naturally occurring gene that can cause cancer when altered. Scientists had never succeeded in reproducing cells in a culture until the HeLa cells, which reproduced an entire generation every 24 hours and never stopped. The cells allowed scientists to perform experiments without using a living human. The researchers discovered that the genome of the HeLa cell line, which has been replicated millions, if not billions of times, has remained relatively stable.” Read more of this story at Slashdot.
