A bird in the hand thanks to a robot that can perch
Land-bound robots? Been there, done that. Researchers at the University of Illinois at Urbana-Champaign are taking things up a notch with a bird-style bot capable of autonomous flight. By replicating the features that enable birds to make a soft landing -- including the flapping wings that help them change direction -- the researchers developed the first micro aerial vehicle (MAV) capable of swooping down to perch on a human hand. The craft forgoes a vertical tail, which birds also lack, to allow for enough agility to land on a small surface. Articulated wings help the robo-bird complete the maneuver successfully, by first gliding into position and then pitching up and slowing down. Who knew perching was so complicated? Besides just providing a super-nifty party trick for these lucky researchers, the autonomous aircraft could be used in urban surveillance, where a small size would come in handy. Check out the MAV in action, along with the press release, after the break.
Researchers develop self-healing electronics, adamantium sadly not included
In today's feature-laden electronics devices, the failure of one little electronic component can scuttle the entire package. To make matters worse, if the damage happens to strike something like a multilayer integrated circuit, then you pretty much need to replace the whole computer chip. But what if the chip could repair itself like a certain vertically challenged Canadian mutant? That's exactly what researchers at the University of Illinois at Urbana-Champaign managed to do after placing self-healing polymers on top of a gold circuit. Once a break occurred, microcapsules with liquid metal filled the crack and restored 99 percent of conductivity in mere microseconds. Self-healing electronics would especially be helpful on things like aircraft, where miles of conductive wires can make finding a break difficult, researchers said. The research is just the latest in a field that also has seen self-healing sensors and shape-memory polymers, but sadly, there's still no word on using this stuff to self-heal a broken heart....
University gets $188 million AMD-based supercomputer, free copy of Norton
It used to be that you only needed a bachelor's degree and elbow patches to be taken seriously as an academic, but now it's all about that 50-petaflop supercomputer with 500 petabytes of storage whirring away in the basement. The University of Illinois used to shop with IBM, but it's just about to have a brand new Cray XK6 installed instead, so it can continue providing computing power to the National Science Foundation's Blue Waters project. It's not all about inciting gadget envy, of course: the machine's unlikely truce of AMD Opteron 6200 16-core processors and NVIDIA Tesla GPUs will help more than 25 teams of scientists to model and understand real-world phenomena, from the damage caused by earthquakes to the way viruses to break into cells. Breakthroughs from these projects will -- hopefully, one day -- make the $188 million total cost of Cray's products and services seem like a bargain. Full details in the PR after the break.
EES packs circuits into temporary tattoos, makes medical diagnostics fashionable
Flexible circuit pioneer John Rogers and his team are at it again. This time he's developing a wearable, ultra-thin circuit that attaches to your skin just like a temporary tattoo. The Epidermal Electronic System (EES) consists of circuits which could contain electrodes capable of measuring brain, heart and muscle activity in the same way an EEG does now, transmitting this data wirelessly to your doctor. Because it's flexible and bonds to the skin, it can be worn for extended periods, unlike traditional diagnostic pads used in hospitals today. In the lab, the devices were solar-powered with embedded photovoltaic cells -- heavier duty circuits would require inductive charging to be practical. Rogers' team also looked into the tech acting as a game controller (they wired it up to someone's throat and played Sokoban with voice commands, still managing to yield a 90 percent accuracy rate), but it's some way off from replacing your SIXAXIS. One of the problems encountered concerned RF communication -- perhaps they should get on the horn to their friends in Oregon and build those fashionable diagnostic pants we're eagerly waiting for.
IBM and NCSA end their Blue Waters affair, go back to just being supercomputing friends
It seems that IBM and the National Center for Supercomputing Applications at the University of Illinois have hit a snag in their once fruitful relationship. After nearly four years of partnering for the Blue Waters petascale supercomputer, the NCSA's recently released a joint statement explaining that IBM's "terminated" its involvement with the project. If you'll recall, IBM was supplying its latest Power7 rigs to get all that data flowing, but the company's now decided that Ol' Blue will require more resources than initially anticipated. Apparently, there were talks to try and keep the spark alive, but since those fell through both have decided to return each others CDs and hoodies assets involved with the project (per contract terms): IBM gives back the money, while the NCSA returns any hardware supplied. The two plan on remaining in touch for future endeavours, and the NCSA doesn't appear to be too down either as it'll be consulting with the National Science Foundation to keep Blue Waters afloat. You'll find the official statement in the source link below, but we've included a video rendition of how we'd like to imagine it past the break. [Photo credit: kosheahan]
Metamaterial printing method inches us closer to invisibility cloaks
In theory, metamaterials are all kinds of awesome -- they can boost antenna strength, focus lasers, and create invisibility cloaks. But, they've been limited to day dreams lab experiments because producing the light-interfering materials in any practical quantity has been difficult and time consuming. John Rogers, a professor at the University of Illinois has figured out a way to print a layered, nano-scale mesh that bends near-infrared light in much larger amounts than previously possible. The new method, based around a plastic stamp, has been used to create sheets of metamaterial measuring a few square inches, but Rogers is confident he can scale it up to several feet. Who knows, by the time the second installment of The Deathly Hallows hits theaters in July you could get the best Harry Potter costume -- one that lets you sneak in without shelling out $13.

StripeSpotter turns wild zebras into trackable barcodes
We've heard plenty of stories over the past few years about tagging animals with RFID chips, but we've never been particularly keen on the idea. Well, now a team of researchers has come up with a much less invasive way of tracking individual animals -- specifically zebras -- by essentially using their stripes as barcodes. StripeSpotter, as it's known, takes an isolated portion of a photograph of a zebra and slices it into a series of horizontal bands. Each pixel in the selection is then fully converted into black or white, and the bands are in turn encoded into StripeStrings, which eventually make up a StripeCode that resembles a barcode. All this information is stored in a database that allows researchers to directly identify particular animals without ever having to get too close. StripeCode may be a zebra-centric application for now, but its developers see it making a mark across the food chain with the inclusion of other distinctly patterned beasts, like tigers and giraffes. Animal tracking hobbyists can get their own free copy of the application by clicking on the source link below.
Researchers find graphene transistors cool themselves, silicon counterparts seethe with envy
We've seen graphene promise some pretty slick tricks already: budget-minded bendable batteries, superior stain resistance, and upping ultracapacitors' energy density. We can now add self-cooling transistors to the list of awesome, yet unfulfilled possibilities for these microscopic sheets of carbon. Using an atomic force microscope, a team of researchers at the University of Illinois led by Professor William King discovered that graphene transistors have a thermoelectric cooling effect where they make their metal connections. This self-cooling is greater than the resistive heating that normally follows the flow of electrons -- meaning graphene-based electronics from the future could make their silicon competition look decidedly uncool in comparison.
Styrofoam touches electrodes to create incredibly fast-charging wonderbatteries
Elon Musk's heart may have already given up on the humble battery, lusting after capacitors, but researchers at the University of Illinois have think there's life in the 'ol cells yet, creating batteries that charge and discharge in seconds. They've found a way to create electrodes using polystyrene beads as a sort of substrate, tiny spheres helping to set the porosity of either the nickel-metal hydride or lithium-manganese capacitor material. By adjusting the size and density of the bean bag innards the team was able to create an electrode porosity of 94 percent, which is just a few ticks short of theoretically ideal for exposing the maximum surface area of the electrode to the battery material. This results in extremely fast charges and discharges, the NiMH cell hitting 90 percent capacity in just 20 seconds and discharging in as quickly as 2.7 seconds. While we don't know just what kind of charging system the team was using to achieve this, even assuming a high-amperage stream of electrons this is still a remarkable feat. But, like most major advances there's a drawback: similar to Toshiba's SCiB batts the capacity of these cells is only about three quarters what it would be using normal battery construction, meaning you'd need roughly 25 percent more mass to get the same range in your ultra-fast charging EV of the future. That might just be a worthy trade-off.
Nanoparticle inks print 3D antennas 'orders of magnitude' better than your boring 2D antenna
If you want better cellphone reception it's time to go small or go home, with researchers at the University of Illinois coming up with a nanoscale printing technique that allows for the creation of so-called 3D antennas. Of course, unless you're hunting for signal in Flatland all antennas are to some degree three-dimensional, but these suckers are printed using nanoparticle silver ink onto a curved substrate, as shown up yonder. The resulting components "exhibit performance metrics that are an order of magnitude better than those realized by monopole antenna designs." In fact these creations are said to approach the Chu-Harrington Limit of theoretical performance in an antenna. Most important? They look pretty darned cool. Shame they'll likely find themselves tucked away inside of a device's chassis -- whenever they actually go into production.
Northwestern University's curvilinear 'eyeball camera' is squishy, just like yours
We've seen gooey lenses before, the Varioptic variety already having found a home in an honest to gosh retail product. But, this is a little different. It's called the "eyeball camera," a curvilinear lens and sensor system developed by a team at Northwestern University and the University of Illinois at Urbana-Champaign. It uses a similar sort of flexible design, this one actuated by varying the pressure of fluids in the device -- higher pressure for convex, lower pressure for concave. Interestingly here the camera sensor itself flexes right along with the lens, and while the maximum zoom is currently a measly 3.5x, higher power is said to be possible -- eventually. No word was given on when we might see these coming to market, so don't pull a Batou and get rid of your fleshy ones just yet.
NCSA prepares for Blue Waters petascale supercomputer, and we've got the video to prove it
How often do you get to see an unboxing of this magnitude? Our buddy Bill at the NCSA (National Center for Supercomputing Applications at the University of Illinois) has been kind enough to hit us up with a video that shows the arrival and installation of the facility's new IBM 780 hardware at the National Petascale Computing Facility. This hardware will allow scientists to prep code in anticipation of the Blue Waters -- which, as previously reported, will be the largest publicly accessible supercomputer in the world when it goes online in 2011, thanks to its over 16,000 Power7 nodes.

Scientists develop implants that melt onto the surface of the brain
Looks like brain implants have just got a lot more effective -- and a lot creepier. Developed by researchers at the University of Pennsylvania School of Medicine in Philadelphia, the new bio-integrated electronics eschew electrodes resembling needles or semi-flexible wires for an ultrathin flexible material that is made partly from silk. Since the new material "essentially melts into place" (scientists compare it to shrink-wrap), it hugs the brain, getting more effective readings than previous technology. It is hoped that the new technology will prove much more effective -- and extremely beneficial for patients with epilepsy, spinal cord injuries, and other neurological disorders. According to John Rogers, Ph.D., the man who invented the flexible electronics at the University of Illinois, "It may also be possible to compress the silk-based implants and deliver them to the brain, through a catheter." We wish these good folks the best of luck with their research -- and we really, really hope that we never have anything shot into our brain with a catheter. PR after the break.
Artificial nose becomes coffee analyzer, sniffs out KIRF Starbucks venues
Artificial schnozzes have been sniffing foreign objects for years now, but rarely are they engineered to sniff out specific things. A team of researchers from the University of Illinois in Urbana-Champaign have done just that, though, with a new snout that acts as a coffee analyzer. Reportedly, the device can "distinguish between ten well-known commercial brands of coffee and can also make a distinction between coffee beans that have been roasted at different temperatures or lengths of time." The significance here is that this distinction is incredibly difficult to make, and it could one day help coffee growers determine whether batches are as good as prior batches on the cheap. More importantly, however, it could help the modern java hunter determine whether or not they're walking in a corporate Starbucks or one of those "branded" kiosks with two-fifths the menu. Brilliant, right?
New materials change color when stressed, making fans of mechanochemical transduction positively giddy
A U.S. Army-funded research project at the University of Illinois has developed a material that changes color when it is met with force or becomes overstressed. Among the examples trotted out in this month's issue of Nature are an elastomer that starts out the color of amber and turns progressively more orange as it's pulled, eventually turning red as it reaches its point of failure and snaps (see the photo on the right). Once relieved of stress, the material reverts to its original color -- and it can be used multiple times. Suggested uses for this technology include parachute cords, climbing ropes, coatings for bridges -- anything, really, that you'd want a heads-up on before imminent failure. Pretty wild, huh?

Eye-shaped camera is shaped like an eye
Some researchers at Northwestern University and University of Illinois have managed to build an eye-like camera that's actually shaped like an eye. Sure, that sounds a tad unimpressive, but the real contribution of this project is the idea of electronics on a curved, flexible surface. The researchers have developed a mesh-like material that carries the photodetectors and electronic components necessary, and they say the resulting camera has a better field of vision than a traditional camera, in addition to conveniently resembling a human eye. Of course, they're a long ways away from communicating with the brain well enough to make an actual fully bionic eyeball, but the curved electronics could have other medical -- and regular form factor-busting, we hope -- applications as well.
Stretchy silicon circuits wrap around complex shapes, like your wife
The first "completely integrated, extremely bendable circuit" was just demonstrated to the world. The team behind the research is led by John Rogers of the University of Illinois at Urbana-Champaign. The process bonds circuit sheets measuring just 1.5 micrometers (50 times thinner than human hair) to a piece of pre-stretched rubber. That allows the circuits to buckle like an accordion when pulled or twisted without losing their electrical properties. Unfortunately, the materials used thus far are not compatible with human tissue. In other words, no X-ray vision implant for you. X-ray contacts perhaps... quantum-computers now, please Mr. Scientists? Watch a circuit buckle in the video after the break.[Via BBC, thanks YoJIMbo]
University of Illinois students show off Lego-based crop harvester
Believe us when we tell you that we've seen Legos used in ways its creators could have never, ever imagined. Thankfully, a team from the University of Illinois found a way to demonstrate a rather useful (read: not bizarre) technology with everyone's favorite building block. By setting up shop at the American Society of Agricultural and Biological Engineers in Minnesota, students were able to show off an autonomous crop harvesting system that transferred heaps of BBs onto unloaders, which then hurried them away to meet artificial deadlines. The setup was configured using Robolab software, and aside from requiring the creators to dump BBs into the harvester, the entire show was put on sans human interaction. Granted, the idea behind all of this is far from fresh, but there's just something strangely satisfying about putting a stash of spare Legos to work for you.
Researchers working on Cell processor supercomputer
For years, Sony and IBM have talked up the power of the Cell processor that's at the core of of every PS3. Now, some University of Illinois researchers are working on finally unlocking that power for the next generation of highly parallel supercomputers. The Illinois News-Gazette has a report on the efforts of user interface experts Marc Snir, Laxmikant Kale and David Kunzman, who say that a computer with a cluster of Cell chips could offer 50 times the performance of a similar sized PC. Squeezing out that performance is no small task, though -- Kale admits "it's going to be a challenge to program it." Despite the team's inside access to Cell technology and tools, the N-G article ends with a joking complaint that the team members "haven't received a PlayStation 3 yet, either." Hey, if you want one that badly, just go to your local store, guys.
Software lets neighbors securely share WiFi bandwidth
Instead of fighting about property lines and whose dog is keeping everyone up at night, researchers from the University of Illinois at Urbana-Champaign want you and your neighbors to get together and share your WiFi signal in a method that supposedly delivers better performance to each individual user. Assistant computer science professor Haiyun Luo and graduate student Nathanael Thompson of the school's Systems, Wireless, and Networking Group have released a free download that analyzes local airwaves and exploits unused bandwidth from one network to complement ones experiencing heavy usage, but always gives users priority access to their own signal. Part of the two-year-old PERM project, the application uses flow-scheduling algorithms to determine bandwidth allocation, and has so-far undergone testing on Linux clients and with Linksys routers. Security is obviously a key concern in such a sharing setup, so PERM developed the software to both "preserve a user's privacy and security, and mitigate the free-riding problem."[Via PCWorld]
