Microsoft reveals Data Explorer tool, gets into the sorbet business (video)

Redmond houses quite a few little teams beavering away on quirky projects and one of those has just gone public with its latest creation. It’s codenamed “Data Explorer”, which perhaps isn’t an ideal codename since it describes exactly what the enterprise-focused service does. Instead of manually searching and copying data into a report, Data Explorer pulls information from SQL databases, spreadsheets and other “random sources” that could be relevant, and then attempts to “clean it up, transform it, merge it together and then publish it out” as a coherent report. You can learn more and sign up for the beta at the source link, or click past the break to watch a Microsoft exec demo the tool using a real-world case study — we found it a bit dense, but you’ll be fine as long as you remember that kids love frozen yogurt.

IDC and Gartner: Lenovo leaps past Dell for second place, still trails HP for the gold

IDC and Gartner have come out with their latest Q3 rankings of the world’s PC manufacturers, which means it’s time for us to do some dissecting. Not much changed at the top of the heap, where, according to IDC, HP still rules the roost with about 18 percent market share (despite that whole PC biz spinoff thing). But the most dramatic shift came from Lenovo, which scurried past Dell for second place, with 13.7 percent market share (13.5, according to Gartner) — a 36.1 percent jump from the third quarter of 2010 (25.2 percent, says Gartner). Dell’s pie slice, on the other hand, shrunk slightly to 12 percent this quarter, down from 12.6 percent last year. On the global scale, meanwhile, PC sales increased by about 3.6 percent compared to Q3 2010 (3.2 percent, in Gartner’s books), though both research firms acknowledged that this figure was well below their respective projections. Why? IDC points to several economic factors, including the threat of a double-dip recession, while Gartner blames the rise of “non-PC devices,” including tablets. Surprise!

MIT researchers suggest graphene could be used to build a better camera sensor

As you may have noticed from the pace of research over the past few years, graphene is promising to make a whole lot of things a whole lot better. Now, it seems, you can also add camera sensors to the list. A team of MIT researchers recently discovered that graphene can serve as a photodetector over a “very wide energy range,” and that it works particularly well in infrared light, where other types of detectors often come up short. That, the researchers say, could open to the door to everything from better nightvision systems to more advanced detectors for astronomical telescopes — not to mention more inexpensive camera sensors in general, since graphene is cheap to work with. What’s more, the researchers also suggest that those same light-detecting abilities could make graphene a good material for collecting solar energy, although they note that there’s still much more research needed to determine if it’s truly an efficient means of generating energy.

Student spends summer turning a tablet into a Braille writer, says mowing lawns is for chumps

Lots of us spend the summer by the pool, sipping Mai Tais and working on our tans, but Adam Duran had better things to do with his vacation. Instead of engaging in such lethargy, Duran attended the Army High Performance Computing Research Center’s summer course held at Stanford, where he and his mentors, Sohan Dharmaraja and Adrian Lew, developed a Braille writer app for tablets. You see, the average 8-key Braille writer is a custom laptop that costs $6,000, so given the paltry pricing on today’s slates, this new solution is considerably more economical. Users place their fingertips on the display and the app populates keys underneath them, rendering tactile indicators of the keys’ location unnecessary. Plus, the virtual keyboard provides a custom fit for your phalanges no matter how big or small they may be. The project has some “technical and legal hurdles to address” before it’s made available to the masses, but here’s hoping they can clear them soon. Video of the app in action after the break.

Ditching DRM could reduce piracy, prices, inconvenience

Down with DRMThis may run counter to what your common sense tells you but, a new paper out of Duke and Rice University says that ditching DRM could actually reduce piracy. The study, which relied on analytical modeling, showed that while copy protection made illegally sharing content more difficult it had a significantly negative impact on legal users. In fact, the researchers say, “only the legal users pay the price and suffer from the restrictions [of DRM].” Many consumers simply choose to pirate music and movies because doing simple things, like backing up a media collection, is difficult with DRMed content. Even the most effective DRM is eventually broken, and fails to deter those already determined to steal. Meanwhile, abandoning these restrictions could increase competition and drive down prices (as well as remove a serious inconvenience), encouraging more people to legitimately purchase content. You can check out the November-December issue of Marketing Science for more details.

NC State researchers team with IBM to keep cloud-stored data away from prying eyes

The man on your left is Dr. Peng Ning — a computer science professor at NC State whose team, along with researchers from IBM, has developed an experimental new method for safely securing cloud-stored data. Their approach, known as a “Strongly Isolated Computing Environment” (SICE), would essentially allow engineers to isolate, store and process sensitive information away from a computing system’s hypervisors — programs that allow networked operating systems to operate independently of one another, but are also vulnerable to hackers. With the Trusted Computing Base (TCB) as its software foundation, Ping’s technique also allows programmers to devote specific CPU cores to handling sensitive data, thereby freeing up the other cores to execute normal functions. And, because TCB consists of just 300 lines of code, it leaves a smaller “surface” for cybercriminals to attack. When put to the test, the SICE architecture used only three percent of overhead performance for workloads that didn’t require direct network access — an amount that Ping describes as a “fairly modest price to pay for the enhanced security.” He acknowledges, however, that he and his team still need to find a way to speed up processes for workloads that do depend on network access, and it remains to be seen whether or not their technique will make it to the mainstream anytime soon. For now, though, you can float past the break for more details in the full PR.

Dipping capacitors and batteries in nanotubes could improve capacity

Super capacitorsStanford researchers figured out that, by dipping electrodes for super capacitors in a solution of carbon nanotubes or a conductive polymer they could increase the charging capacity by up to 45-percent. The team started working with composite electrodes of graphene and manganese oxide, since manganese is cheap and plentiful, but were hamstrung by its low conductivity. The thin coating of more conductive material greatly boosted the capacitance of the electrodes, and thus their ability to hold a charge. Further tests are still required to find the actual energy density of the dipped electrodes, but lead researchers Yi Cui and Zhenan Bao are already working on a way to apply the same technique to batteries.

Piezoelectric system turns your balmy breath into pungent power

Researchers at the University of Wisconsin-Madison have come up with a way to produce electricity from just about the most renewable source known to man — his own breath. It’s all thanks to a plastic microbelt developed by engineers Xudong Wang, Chengliang Sun and Jian Shi. Made of a material known as polyvinylidene fluoride (PVDF), this belt produces an electric charge whenever low-speed airflow passes over it and causes it to vibrate — a result of that vaunted piezoelectric effect. Eventually, Wang and his team were able to tinker with their system to the point where it could produce enough current to charge small electronic devices. “The airflow of normal human respiration is typically below about two meters per second,” Wang explained. “We calculated that if we could make this material thin enough, small vibrations could produce a microwatt of electrical energy that could be useful for sensors or other devices implanted in the face.” The researchers say their technology could be used to power smaller biomedical devices like blood monitors and pacemaker batteries, which typically don’t demand vast amounts of energy. No word yet on when this system could make its way to the mainstream, but we’ll be waiting with bated breath.

Invisibility cloak made of carbon nanotubes uses ‘mirage effect’ to disappear

If the phrase “I solemnly swear I’m up to no good” means anything to you, you’ll be happy to know that scientists have come one step closer to a Potter-style “invisibility cloak” so you can use your Marauder’s Map to the fullest. With the help of carbon nanotubes, researchers have been able to make objects seem to magically vanish by using the same principle that causes mirages. As anyone who’s been especially parched along Route 66 knows, optical illusions occur when heat changes the air’s temperature and density, something that forces light to “bend,” making us see all sorts of crazy things. Apply the same theory under water using nanotubes — one molecule carbon coils with super high heat conductivity — and scientists can make a sheet of the stuff “disappear.” Remember, it only works underwater, so get your gillyweed ready and check out the video after the break.
