Shocker! Excessive cell phone chatter is seriously annoying
It looks like science has confirmed what we were all thinking: being party to one half of someone else's cell phone conversation is seriously annoying. In a paper to be published in an upcoming issue of Psychological Science, Cornell University grad student Lauren Emberson explains it thusly: not being able to hear the responses to one part of the convo proves inherently unsettling, because it's unpredictable, and thus makes it hard to concentrate. According to Science News, Emberson found that, while performing "attention tasks" in silence or while listening to various conversations (including a normal, two-sided conversation, a one-sided cell phone conversation, and a monologue) accurate completion of the tests "declined slightly but to a statistically significant extent" during the one-sided conversations, relative to the other conditions. Now if someone could only do a similar study involving The Best Of Sade, maybe we could cite it the next time we have to ask the barista at the Liberty Avenue Crazy Mocha to turn down the music while we're trying to read.
Fifth Ave Apple Store is NYC's fifth most-photographed location
Philip DeWitt at Apple 2.0 is reporting that Apple's Fifth Avenue retail store is now New York City's fifth most-photographed location. The ranking is according to a year-old analysis of 35 million Flickr images by Cornell University students on a university supercomputer. So which four landmarks are beating the Fifth Ave store? The Empire State Building, Times Square, Rockefeller Center, and Grand Central Station, in that order. It's hard to believe the Apple Store beat the Statue of Liberty (ranked 7th). Cornell's study can be read here (PDF). It's an interesting list of the most photographed cities and landmarks around the world. Even when you take all the landmarks of the entire planet into account, the Fifth Avenue Apple Store is still ranked 28th globally. Ironically enough Peter Bohlin, the man who designed the hottest computer store on the planet, has been good-naturedly called "a total computer illiterate" by his Philadelphia partner. When Steve Jobs met with Bohlin they wondered how to turn the property, part of which was underground, into a space people would want to enter. The answer, Bohlin told Philly.com, was to make the cube into a giant skylight. "There has always been something magical about a glass building." And thus a star -- er, cube -- was born.
Cornell's switchable adhesive device keeps candy from falling, could let you dance on the ceiling (video)
Climbing walls is one of those odd feats that scientific establishments seem compelled to master -- despite there being few practical applications beyond the ultimate in Marvel-themed Halloween attire. The latest to tackle the challenge are Paul Steen and Michael Vogel from Cornell University, who have stolen the sticky-feet technique of a Floridian beetle that apparently failed to file a patent. The technique relies on the surface tension of water and capillary action of fluids forced through thousands of microscopic holes. When moisture is pushed through the holes it creates a suction on a smooth surface, enough at this point for the team's prototype to hold a weight of 30 grams. When the water is retracted the suction disappears. If all goes well, future implementations of a similar size could hold 15 pounds, meaning with enough of them you could climb a wall -- without leaving a sticky mess behind.

Cornell gurus look to carbon nanotubes for efficient solar cells
You know what we love? Solar-powered gadgets, and carbon nanotubes. Oh, and Ivy League schools. Boffins from Cornell University are now looking to use the multifaceted carbon nanotube instead of silicon to develop efficient solar cells, and judging by the glacial pace at which solar cell efficiency is improving, we'd say the sector could use the boost. The researchers have already fabricated, tested and measured a simple solar cell (called a photodiode, just so you know) that was formed from an individual carbon nanotube. The tube was essentially a rolled-up sheet of graphene, and while the inner workings would take days to explain, the gist of it is this: "The nanotube may be a nearly ideal photovoltaic cell because it allowed electrons to create more electrons by utilizing the spare energy from the light."So, solar-powered F-350 trucks are now a possibility for next year, right?[Via Graphene-Info]
Video: Cornell's autonomous robot sub wins competition, our hearts
Cornell sure seems to be doing its part to usher in a world where robots call the shots and humans spend most of their time cowering in the corners of bomb-out buildings. Researchers at the school have variously applied their brain matter (and we're guessing the occasional government check) to such sticky problems as robot consciousness, distance walking, and complications related to using robotics in zero gravity. And now we've heard that the school has just won something called the Autonomous Underwater Vehicle Competition. The vehicles entered in the 12th annual AUVC (which was held at the Space and Naval Warfare Systems Center in San Diego) ran an underwater obstacle course that involved bombing things, firing torpedoes, and eventually recovering a suitcase with "secret documents" (or old issues of 2600: The Hacker Quarterly, depending on who you believe). You can see the thing in action for yourself in the video after the break.[Via GoRobotics.net]
Quest for invisibility cloaks revisited by two research groups
After a brief period of no news, it's time to revisit the world of invisible cloaks. Inspired by the ideas of theoretical physicist John Pendry at Imperial College, London, two separate groups of researchers from Cornell University and UC Berkeley claim to have prototyped their own cloaking devices. Both work essentially the same way: the object is hidden by mirrors that look entirely flat thanks to tiny silicon nanopillars that steer reflected light in such a way to create the illusion. It gets a bit technical, sure, but hopefully from at least one of these projects we'll get a video presentation that's sure to make us downright giddy.
New silicon film ferroelectric may pave the way for instant-on computers (or maybe not)
While the gang at Toshiba are still trying to bring FeRAM to the masses, a team of researchers at Cornell University have devised a new ferroelectric material composed of silicon and strontium titanate that they say can be used (someday!) to build "instant on" transistors. And you know what that means -- instant on computers for students, and instant on death rays for future robot armies. To coax the generally mild-mannered strontium titanate into acting "ferro-electrified" (not an actual scientific term), researchers grew it onto a silicon substrate using a process known as epitaxy. The material literally squeezed itself within the spaces of the silicon molecules, which gave it ferroelectric properties. As you may have guessed, this research was partially funded by the Office of Naval Research -- so the "death ray" remark may not be so off base, after all. We'll keep an eye out.[Via Daily Tech]
Scientists develop 'coin sorter' for nanoparticles, first-ever nanofluidic device with complex 3D surface
The National Institute of Standards and Technology (NIST) and Cornell University have banded together and formed what they're touting is the first nanoscale fluidic device with a complex three-dimensional surface. The staircase-shaped prototype is 10nm at its tiniest and 620nm at its tallest -- all smaller than the average bacterium, and a departure from the usual flat, rectangular-shaped fare. According to the press release, it can manipulate nanoparticles by size, similar to how coin sorters separate your pocket change. Potential uses includes helping to measure nanoparticle mixtures for drug delivery or gene therapy, or the isolation / confinement of individual DNA strands.

Artificial Intelligence solves boring science experiments, makes interns obsolete
Researchers at Aberystwyth University in Wales have developed a robot that is being heralded as the first machine to have discovered new scientific knowledge independently of a human operator. Named Adam, the device has already identified the role of several genes in yeast cells, and has the ability to plan further experiments to test its own hypotheses. Ross King, from the university's computer science department, remarked that the robot is meant to take care of the tedious aspects of the scientific method, freeing up human scientists for "more advanced experiments." Across the pond at Cornell, researchers have developed a computer that can find established laws in the natural world -- without any prior scientific knowledge. According to PhysOrg, they've tested the AI on "simple mechanical systems" and plan on applying it to more complex problems in areas such as biology to cosmology where there are mountains of data to be poured through. It sure is nice to hear about robots doing something helpful for a change.[Thanks, bo3of]Read: Robo-scientist's first findingsRead: Being Isaac Newton: Computer derives natural laws from raw data
New robotic arm promises to mind Newton's third law
Don't you hate it how simply moving a robotic arm in a microgravity environment can produce enough negative reaction forces to alter a spacecraft's orientation? Well, a group of researchers from Cornell University have now devised a new type of robot arm that they say could make that pesky problem a thing of the past. To do that, they've employed a device known as a control-moment gyroscope (or CMG) instead of a motor to control the arm's joints, which not only reduces the amount energy required to move the arm, but lets it move faster as well. As you can see above, they've already tested the arm on board NASA's famous Vomit Comet, but there's no indication just yet as to when or if the arm will actually see action in space.
Fab@Home shows you how to build a fabber on your own
Fabbers, or 3D printers, or prototyping machines, are traditionally used in product manufacturing to get an idea of how a product sketch will look and feel in real life. Just like many technological products, a homebrew open-source community has started up around fabbers -- a new one has just begun at Cornell University, appropriately called Fab@Home. The project, which is already several weeks old, has resulted in some pretty awesome projects, including a fabbing chocolate machine done by a high school student in Kentucky that makes some pretty tasty looking treats. As you'd expect, the group has put together a set of instructions and accompanying software (Windows only, sorry Mac and Linux fans) so that you too can build your own fabber, chocolate or otherwise. No word on if you can make a totally fab Fabergé egg with a fabber, however.[Via Hack A Day]
Nanotech napkin to detect bacteria, viruses
You know how your mother told you to wipe your mouth after you eat? Well, if you're afraid that your eating area is infested with biohazards, you may find yourself wiping a lot more in the near future. Researchers at Cornell University announced last week that a "biodegradable absorbent wipe" is in the works, which would signal -- possibly through a color change -- if the surface it touches is infested with bacteria, viruses, or other "dangerous substances" by employing embedded nanofibers. Prof. Margaret Frey of Cornell says that this napkin is still "a few years away" from being available to the public -- so in the meantime, you may still want to use that e-nose to detect bugs that infect your bagged spinach food supply.[Via Sci Fi Tech]
