A 30-Picowatt Processor For Sensors 93

Roland Piquepaille writes "University of Michigan (U-M) researchers have developed an ultra low power microchip which 'uses 30,000 times less power in sleep mode and 10 times less in active mode than comparable chips now on the market.' It only consumes 30 picowatts in sleep mode, which means that a simple watch battery could power the chip for more than 200 years. Of course, this is not a processor for your next computer. It is designed for sensor-based devices such as medical implants, environment monitors or surveillance equipment. However, the design is very clever." Roland's blog has some more information, including a die picture of the chip, known as the Phoenix.
It's funny.  Laugh.

Smarter Teens Have Less Sex 1285

Tech.Luver writes "Gene Expression reports, "Tyler Cowen quotes from a new study testing the relationship between grades and delayed sexual activity. Last December I passed a paper along to Razib showing that high-school age adolescents with higher IQs and extremely low IQs were less likely to have had first intercourse than those with average to below average intelligence. (i.e. for males with IQs under 70, 63.3% were still virgins, for those with IQs between 70-90 only 50.2% were virgin, 58.6% were virgins with IQs between 90-110, and 70.3% with IQs over 110 were virgins) In fact, a more detailed study from 2000 is devoted strictly to this topic, and finds the same thing: Smart Teens Don't Have Sex (or Kiss Much Either).

Feed FCC declares in-flight cellphones a dead issue for now (engadget.com)

Not that there was ever really much doubt that the rest of the commission would take Chairman Kevin Martin's lead, but now it's official: in-flight cellphones are a dead issue for the time being, as far as the FCC is concerned at least. The masters of the airwaves issued a statement today saying that they would not move forward with the proceedings which had been underway to revisit the current ban, citing "insufficient technical information on whether the use of cellular phones onboard aircraft may cause harmful interference to terrestrial networks." Of course the fact that thousands of people called the agency bitching and moaning about the likely cacophony of flying chatterboxes probably didn't help matters much, nor did the blasé attitude most of the major airlines seem to have about this. Hopeful sky talkers can take some solace in the commission's claim that it could reconsider its decision in the future pending "appropriate technical data," and if nothing else, AirCell's impending in-flight WiFi will likely enable VoIP sooner rather than later -- although voice services will initially be locked out. So, no gabbing on the plane quite yet, which is just fine with us, because we prefer to be knocked out cold the whole flight anyway.

Feed Fired Reporters Start Their Own News Website (techdirt.com)

A group of eight former employees of the Santa Barbara News-Press who claim they were illegally fired for supporting efforts to unionize the newsroom have decided to keep on reporting via a website they set up for themselves. They're covering all sorts of local news, including school relocation plans and property taxes. They claim that this is only until they get their jobs back -- but if the conditions at their old newspaper job were so bad, it makes you wonder why they don't just go ahead and make this new project a full-time effort and do things right. If the Santa Barbara News-Press really is treating its employees as badly as is being made out in reports about the labor dispute, why not create some competition and bring on the best employees from the newspaper to show the management of that paper what happens when you treat employees poorly?

Diebold Goes 0 For 3 In Massachusetts Case 119

beetle496 writes "ComputerWorld reports that last week a judge denied Diebold's request to block ES&S pact with Massachusetts. This is a follow-up to the earlier discussion here after Diebold contended that the state had erred in selecting the machines of its rival, citing accessibility provisions of the HAVA law. Quoting: 'Diebold's request for an injunction to block the execution of the contract with ES&S was rejected... The judge also denied Diebold's request to have an accelerated discovery process and to keep the state's legal team from viewing internal Diebold documents... "The suit is still there, but they went zero for three yesterday," the spokesman said.' The actual accessibility concerns have been discussed over at the TEITAC listserv, including a few telling observations from experts familiar with accessible voting and at least one state insider."

Feed Drugs For Parkinson's Disease May Ease Stroke-related Disability (sciencedaily.com)

Scientists have untangled two similar disabilities that often afflict stroke patients, in the process revealing that one may be treatable with drugs for Parkinson's disease. Researchers showed that stroke damage in a brain region known as the putamen is strongly linked to motor neglect, a condition that makes patients slow to move toward the left side.

Feed Stop Signs: Study Identifies 'Braking' Mechanism In The Brain (sciencedaily.com)

As wise as the counsel to "finish what you've started" may be, it is also sometimes critically important to do just the opposite -- stop. And the ability to stop quickly may depend on a few "cables" in the brain, according to research by UC San Diego cognitive neuroscientist Adam Aron.

Feed New Technology For Manufacturing Flexible Solar Cells (sciencedaily.com)

The University of Delaware's Institute of Energy Conversion has developed new technology for the manufacture of flexible solar cells, which could reduce the costs associated with the use of photovoltaic energy while at the same time expanding possible applications. The system, in which there has been commercial interest, enables the more efficient manufacture of the flexible solar cells in long sheets using roll-to-roll reactors, much like newsprint speeding through a press.

Feed Are All Male's Liars And Cheaters? Yes -- If They're Crayfish! (sciencedaily.com)

Intimidation and threats are common throughout society, whether it's in the school playground, sporting arena or boardroom. Threatening behavior is equally widespread among nonhuman animals. Individuals signal their superior strength to competitors to obtain food, resolve territorial disputes and acquire mates. Current theory insists that signals of strength should be honest. Surprisingly researchers have found that dishonest signals are used routinely during dominance disputes by male Australian crayfish.
