Cotton Is the Fabric of Your Lights, Your MP3 Player, Your Cell Phone

ScienceDaily (Mar. 10, 2010) — Consider this T-shirt: It can monitor your heart rate and breathing, analyze your sweat and even cool you off on a hot summer's day. What about a pillow that monitors your brain waves, or a solar-powered dress that can charge your MP3 player? This is not science fiction -- this is cotton in 2010.

While the verdict is still out with regard to consumer appetites for a 3rd portable computing device, PC makers are betting the farm on consumer interest in tablets that fill the gap between small-screened smartphones and bulky (by comparison) netbooks/laptops. We've already seen an uptick in tablet devices on display at the big CES and CeBIT trade shows, now tablet and MID device vendors look ready to blow out Computex when it kicks off on June 1st in Taipei. According to Roy Chen, ARM's ODM manager for worldwide mobile computing, more than 50 ARM-based tablet PCs will launch in 2010 starting in Q2 with "a lot more" landing in the third quarter -- a date that just happens to line up with the most optimistic Chrome OS launch schedule. ARM's seeing so much interest that it had to rent additional floor space to show off the devices. Chen said that many of the tablets are slated for China although all of the world's top 10 carriers have signed up as well. ARM was showing off two Android based tablets at the press event, including the 7-inch Compal device (pictured above) we gave a whirl at CES. Let's just hope that tablet makers have plans for some compelling content and service hook-ups with a focus on the user experience -- 50 near-identical slabs of touchscreen computing won't generate much enthusiasm around here.

Martin Jetpack priced at $86,000, mere mortals will soon be able to buy one too

By Vladislav Savov posted Mar 10th 2010 4:24AM

Tired of the limited legroom, bad food, and worse movies you have to put up with during a flight? Well, it's time to bust out your company credit card and get yourself a Martin Jetpack, which has just become the first commercially available jetpack. Driven by a pair of washing machine-sized fans strapped to your back, this personal transporter will give you a pretty cool 30 minutes of flight time and comes with a bunch of redundancy systems to ensure any mistakes don't turn fatal. The rotors are built out of a carbon / Kevlar composite and are powered by a two-liter V4 two-stroke engine capable of delivering 200hp (or 150kW). Good old gasoline is the fuel of choice here and private individuals are expected to be offered the chance to fulfill every geek and geekette's dream later this year. Just make sure you have $86,000 lying around to fund it.

To Remember the Good Times, Reach for the Sky

ScienceDaily (Mar. 8, 2010) — Simple motor actions, like moving marbles upward or downward between two cardboard boxes, may not seem meaningful. But a study published April 2010 inCognition shows that motor actions can partly determine people's emotional memories.

ScienceDaily (Mar. 8, 2010) — Doctors treat millions of children with Ritalin every year to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning.

50% Efficiency Boost From New Fuel Injection System

Posted by kdawson on Tuesday March 09, @08:14AM
from the only-four-years-out dept.

chudnall notes a Technology Review story on a new gas engine injection system that promises increased efficiency of up to 50%."The key is heating and pressurizing gasoline before injecting it into the combustion chamber, says Mike Rocke, Transonic's vice president of business development. This puts it into a supercritical state that allows for very fast and clean combustion, which in turn decreases the amount of fuel needed to propel a vehicle. The company also treats the gasoline with a catalyst that 'activates' it, partially oxidizing it to enhance combustion."

Sea Squirt Offers Hope for Alzheimer's Sufferers

ScienceDaily (Mar. 3, 2010) — Alzheimer's disease affects an estimated 27 million people worldwide. It is the most common form of age-related dementia, possibly the most feared disease of old age. There is no cure, and the available drugs only help to relieve symptoms without slowing progression of the disease. One of the characteristic changes in the brains of Alzheimer's patients is the accumulation of plaques and tangles; currently, the best hope for curing or at least slowing the disease lies in developing drugs that target this buildup. Some drugs are already in clinical trials, but there is still a pressing need for more research, and for more and better drugs directed against both known and novel targets.

Chilean Quake Likely Shifted Earth’s Axis, NASA Scientist Says

If you think you’ve got one of the coolest monitor setups in town, you’ll want to take a look at this jaw-dropping 40-monitor setup. While the initial idea was to set up 60 monitors, consisting of a mix of 19-inch and 24-inch monitors, but in the end the maker settled for 40 units of 24-inch monitors. 6 computers power the whole setup, and they’re powered by Intel’s Core i7 975 processors, 24GB of DDR3 memory, two SLC SSDs in RAID0 configuration, not to mention some NVIDIA NVS 420s and NVIDIA 9800GTs. In case you’re wondering what this is all for, it’s supposedly used for “intraday trading and development”, but you would be forgiven for thinking that it was the brain of a robot planning to take over planet Earth, after all, why would you see such a cool setup for mundane tasks, right?

An Exercise To Model a "Solar Radiation Katrina"

Posted by kdawson on Monday March 01, @08:17AM
from the transformer-fires dept.

Hugh Pickens writes in with an update on the warnings we discussed a year back about the dangers of a "solar Katrina." Now NPR is reporting on a tabletop exercise mounted in Boulder, Colorado by government workers attempting to model the effects of a worst-case solar electromagnetic storm."...an exercise held in Boulder, Colorado, has investigated what might happen if the Earth were struck by a solar storm as intense as the huge storms that occurred in 1921 and 1859— a sort of solar Katrina — and researchers found that the impact is likely to be far worse than in previous solar storms because of our growing dependence on satellites and other electronic devices that are vulnerable to electromagnetic radiation. 'In many ways, the impact of a major solar storm resembles that of a hurricane or an earthquake,' says FEMA Administrator Craig Fugate, except that a solar Katrina would cause damage in a much larger area — power could be knocked out almost simultaneously in countries from Sweden to Canada and the US. In the exercise, the first sign of trouble came when radiation began disrupting radio signals and GPS devices, says Tom Bogdan, who directs the Space Weather Prediction Center. Ten or 20 minutes later electrically charged particles 'basically took out' most of the commercial satellites that transmit telephone conversations, TV shows, and huge amounts of data we depend on in our daily lives. But the worst damage came nearly a day later, when the solar storm began to induce electrical currents in high voltage power lines strong enough to destroy transformers around the globe, leaving millions of people in northern latitudes without power."

Mother's Sensitivity May Help Language Growth in Children With Autism Spectrum Disorder

ScienceDaily (Feb. 25, 2010) — A new study by researchers from the University of Miami shows that maternal sensitivity may influence language development among children who go on to develop autism. Although parenting styles are not considered as a cause for autism, this report examines how early parenting can promote resiliency in this population.

ScienceDaily (Feb. 24, 2010) — University of California researchers found that the incidence rate for all causes of dementia in people age 90 and older is 18.2% annually and significantly increases with age in both men and women. This research, called "The 90+ Study," is one of only a few to examine dementia in this age group, and the first to have sufficient participation of centenarians.

Seeing a Boeing 747 destroy a liquid-fueled ballistic missile with a megawatt-class laser is undoubtedly one of the tech highlights of the year so far. Unfortunately, as impressive as the demonstration was, it's unlikely to be militarized in its current state. While the Air Force's chief of staff, General Norton Schwartz, called the demonstration "a magnificent technical achievement," he has no intention of introducing the fat tub of chemical goo into the theater of war. Solid state lasers are the future "coin of the realm," according to Schwartz, not Boeing's chemical laser which he claims, "does not represent something that is operationally viable." Of course, the chemical core of the laser was just a single component of the ALTB that managed to track, target, and destroy a moving projectile from an airborne platform. And while the technology might not be viable for broad deployment, that doesn't mean that it won't be fitted into a special forces AC-130 Gunship for covert operations until solid state lasers (currently limited to about 100kW) achieve megawatt status. Just saying.

Darpa funds invisible, shoot-through shield

By Joshua Topolsky

posted Jun 21st 2007 10:14PM

In a move seemingly influenced in equal parts by Halo and David Lynch's film Dune, Darpa has announced that it's ponying up $15 million to develop one-way-invisible, self-healing, shoot-through shields for use in urban combat. While the Pentagon's research division acknowledges that there are "significant technical obstacles" in the process, it's fairly gung-ho about developing a technology combining metamaterials, 'coded' obscurant systems, and a bunch of other stuff no one really understands.

DARPA longs for magnetic body healers, crazy respawn camps

By Darren Murph posted Feb 24th 2010 4:22AM

Even DARPA understands that its futuristic bubble shield can be penetrated given the right circumstances, and when it does, the soldier behind it is going to need some serious healing. In a hurry. In the entity's newest budget, there's $6.5 million tucked away "for the creation of a scaffold-free tissue engineering platform, which would allow the construction of large, complex tissues in vitro and in vivo." As you well know, this type of mad science has been around for quite some time, and now it looks as if DARPA is ready for the next best thing: "non-contact forces." Put simply, this alludes to replacing scaffolds with magnetic fields or dielectrophoresis, which could purportedly "control cell placement in a desired pattern for a sufficient period of time to allow the cells to synthesize their own scaffold." It's still too early to say how close we are to being able to instantaneously heal soldiers on the battlefield, but frankly, the public is apt to never know for sure.

Google executives found guilty of violating privacy of student bullied on video

Breaking News

Hold tight kids, internet privacy laws just got flipped upside down. An Italian judge found three Google executives guilty of violating the privacy of an Italian student who was bullied in a 2006 video posted on Google Video. The video resided on the site for two months before it was brought to Google's attention and pulled. None of the executives were involved in any way in the making of the abhorrent video. Nevertheless, Italian judge Oscar Magi sentenced the execs to a six-month prison sentence but cleared them of defamation charges. No jail time is expected, however, since any sentence of less than 3 years is typically commuted in Italy for those without a criminal record.

As you can imagine, Google has responded with vigor. In a post on Google's official blog, Google calls the decision "astonishing" citing the assistance it provided to local police in helping bring those who uploaded the video (and bullied the autistic child) to justice. More importantly, Google says that the decision "attacks the very principles of freedom on which the Internet is built." On the surface, we have to agree. Here's how Google describes the dystopian knock-on effect should this ruling take precedent:

"European Union law was drafted specifically to give hosting providers a safe harbor from liability so long as they remove illegal content once they are notified of its existence. The belief, rightly in our opinion, was that a notice and take down regime of this kind would help creativity flourish and support free speech while protecting personal privacy. If that principle is swept aside and sites like Blogger, YouTube and indeed every social network and any community bulletin board, are held responsible for vetting every single piece of content that is uploaded to them - every piece of text, every photo, every file, every video - then the Web as we know it will cease to exist, and many of the economic, social, political and technological benefits it brings could disappear."

Quantum Leap for Phonon Lasers

ScienceDaily (Feb. 24, 2010) — Physicists have taken major step forward in the development of practical phonon lasers, which emit sound in much the same way that optical lasers emit light. The development should lead to new, high-resolution imaging devices and medical applications. Just as optical lasers have been incorporated into countless, ubiquitous devices, a phonon laser is likely to be critical to a host of as yet unimaginable applications.

ScienceDaily (Feb. 23, 2010) — University of Utah scientists developed an easier way for meteorologists to predict snowfall amounts and density -- fluffy powder or wet cement. The method has been adopted by the National Weather Service for use throughout Utah -- and could be adjusted for use anywhere.

OU professor submerses laptop in liquid nitrogen, smashes it to prove a point (video)

By Darren Murph posted Feb 21st 2010 2:54PM

Hey, students -- pay attention. Not to us, mind you, but to the syllabus provided by your professor. Kieran Mullen, a physics professor at the University of Oklahoma, has a fairly strict rule about gadgets in class: there won't be any, ever, under any circumstances. Balk all you want (understandable given his own clipped-on cellie), but if you sign up for this guy's class, you'll be flipping your phone to "off" and leaving your laptop in the dormitory. And if you try to blaze your own path and slip that netbook into the back row, you might leave bitterly disappointed. As you'll see clearly in the video past the break, Mr. Mullen sought to make a visual point that laptops weren't allowed in class (he calls them "a distraction"), and while it seems that the whole stunt was premeditated, most students acknowledged that his point was driven home. In short, he took a defunct machine, submerged it in liquid nitrogen, and proceeded to make the following statement:

"This is just liquid nitrogen, so it alone won't hurt the computer. But this will."

Dry Winters Linked to Seasonal Outbreaks of Influenza

ScienceDaily (Feb. 23, 2010) — The seasonal increase of influenza has long baffled scientists, but a new study published in PLoS Biology has found that seasonal changes of absolute humidity are the apparent underlying cause of these wintertime peaks. The study also found that the onset of outbreaks might be encouraged by anomalously dry weather conditions, at least in temperate regions.

ScienceDaily (Feb. 23, 2010) — Biogas from refuse produces 95 per cent less greenhouse gas emissions than gasoline, according to a new research report. With a few simple improvements to the biogas plants, the figure can rise to 120 per cent -- i.e. biogas becomes more than climate neutral. This can be compared with the standard figures used today, which indicate that biogas produces 80 per cent lower emissions than gasoline.

Midday nap markedly boosts the brain's learning capacity

If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don't roll your eyes. New research shows that an hour's nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter.

Students Build 2752 MPG Hypermiling Vehicle

MikeChino sends along this awe-inspiring excerpt: "Think claims of electric vehicles that get over 200 MPG are impressive? Try this on for size: a group of mechanical engineering students at Cal Poly have developed a vehicle that can get up to 2752.3 MPG -- and it doesn't even use batteries. The Cal Poly Supermileage Team's wondercar, dubbed the Black Widow, has been under construction since 2005. The 96 pound car has three wheels, a drag coefficient of 0.12, a top speed of 30 MPH, and a modified 3 horsepower Honda 50cc four-stroke engine. It originally clocked in at 861 MPH and has been continuously tweaked to achieve the mileage we see today." It's not quite as street-worthy, though, as Volkswagen's 235 MPG One-Liter concept.
