HP Creates First Hybrid Memristor Chip 155

Posted by timothy from the stitch-in-time dept.
An anonymous reader writes "HP researchers have built the first functioning hybrid memristor-transistor chip. Lead researcher Stanley Williams and his team built the very first memristor — the '4th fundamental element' of integrated circuits after resistors, capacitors and inductors — back in April. Memristors can remember their resistance, leading to novel electronic capabilities. The new FPGA circuit uses memristors to perform tasks normally carried out by (many more) transistors and is therefore smaller, more power efficient and cheaper to make, HP says. Memristors could also turn out to be a more compact, faster alternative to flash memory."

New Star Trek Trailer 591

Posted by CmdrTaco from the please-jj-don't-hurt-em dept.
roelbj writes "The full trailer to the next Star Trek movie is now available at the movie's official web site. The upcoming J.J. Abrams-helmed installment represents a changing of the guard, a reboot of the franchise, and a return to the original-series crew. It should prove interesting to see how Abrams' writing staff (Cloverfield, Lost, Alias) tackles the Star Trek universe and all the continuity and baggage that comes with it."

No, you're thinking of the "Asshole detector." It is a very simple device which beeps and flashes when an asshole touches it. The directions on the bottom read "if the device is not beeping and flashing, then you are not an asshole, or the batteries are dead. Please check the batteries."

I'm not sure how the R & D is coming for the asshole-detector detector though.

Scientists Turn Tequila Into Diamonds 249

Posted by ScuttleMonkey from the still-working-on-a-use-for-the-worm dept.
MaxwellEdison writes "Researchers, oddly enough from the National Autonomous University of Mexico, have found a way to make diamond films using tequila. They were originally testing methods of creating the films with organic solutions like acetone when it was noticed the ideal ratios of water and ethanol turned out to be about 80 proof, or 40% alcohol. '"To dissipate any doubts, one morning on the way to the lab I bought a pocket-size bottle of cheap white tequila and we did some tests," Apátiga said. "We were in doubt over whether the great amount of chemicals present in tequila, other than water and ethanol, would contaminate or obstruct the process, it turned out to be not so. The results were amazing, same as with the ethanol and water compound, we obtained almost spherical shaped diamonds of nanometric size. There is no doubt; tequila has the exact proportion of carbon, hydrogen and oxygen atoms necessary to form diamonds."'"

Silencing a Hard Drive Using Household Items 275

Posted by kdawson from the bread-olives-and-silence dept.
Reader Justblair recommends his blog entry detailing how he made a hard drive silencer for a pittance. "This article demonstrates a very easy-to-make hard drive silencer that not only outperforms most commercially available devices, but is cheaper to implement as well. Requiring very little in fabrication skills, it is an ideal addition to a media PC or HTPC. It may even suit you if your head is aching after many hours of being whined at by your hard drive."

Is Ubuntu Getting Slower? 544

Posted by CmdrTaco from the slow-like-a-fox dept.
An anonymous reader writes "Phoronix has a new article where they provide Ubuntu 7.04, 7.10, 8.04, and 8.10 benchmarks and had ran many tests. In that article, when using an Intel notebook they witness major slowdowns in different areas and ask the question, Is Ubuntu getting slower? From the article: 'A number of significant kernel changes had went on between these Ubuntu Linux releases including the Completely Fair Scheduler, the SLUB allocator, tickless kernel support, etc. We had also repeated many of these tests to confirm we were not experiencing a performance fluke or other issue (even though the Phoronix Test Suite carries out each test in a completely automated and repeatable fashion) but nothing had changed. Ubuntu 7.04 was certainly the Feisty Fawn for performance, but based upon these results perhaps it would be better to call Ubuntu 7.10 the Gooey Gibbon, 8.04 the Hungover Heron, and 8.10 the Idling Ibex.'"

100x Denser Chips Possible With Plasmonic Nanolithography 117

Posted by timothy from the powers-of-10-are-nice dept.
Roland Piquepaille writes "According to the semiconductor industry, maskless nanolithography is a flexible nanofabrication technique which suffers from low throughput. But now, engineers at the University of California at Berkeley have developed a new approach that involves 'flying' an array of plasmonic lenses just 20 nanometers above a rotating surface, it is possible to increase throughput by several orders of magnitude. The 'flying head' they've created looks like the stylus on the arm of an old-fashioned LP turntable. With this technique, the researchers were able to create line patterns only 80 nanometers wide at speeds up to 12 meters per second. The lead researcher said that by using 'this plasmonic nanolithography, we will be able to make current microprocessors more than 10 times smaller, but far more powerful' and that 'it could lead to ultra-high density disks that can hold 10 to 100 times more data than today's disks.'"

B&W TV Generation Has Monochrome Dreams 343

Posted by kdawson from the horse-of-a-different-color dept.
Ant writes "The Telegraph reports that people over 55 who were brought up watching a monochrome TV set are more likely to dream in black and white, even years later. New research suggests that the type of television you watched as a child has a profound effect on the color of your dreams. While almost all under-25s dream in color, many over-55s, all of whom were brought up with B&W sets, often still dream in monochrome. The study, out ot Dundee University, used a small number of subjects under 25 or over 55 and the results suggest that '... there could be a critical period in our childhood when watching films has a big impact on the way dreams are formed ... [B]efore the advent of black and white television all the evidence suggests we were dreaming in color.'"
