Street View heads back to the Antarctic, visits historic landmarks (video)

Terrence O'Brien — Tue, 17 Jul 2012 13:00:00 -0400

Google has already taken us on a trip to the frigid shores of Antarctica before. Now the search giant is back with even more panoramic images, this time from deeper inside the frozen continent. With help from the Polar Geospatial Center at the University of Minnesota and the New Zealand Antarctic Heritage Trust (not to mention a light-weight tripod and a fisheye lens), Street View can now bring to you the wonders of our most southern land mass. This isn't a short stroll in the footsteps of penguins either -- the ceremonial South Pole and Shackleton's Hut are among the numerous landmarks that get exposed to Google's image sensors. Enjoy the quick tour above and the video after the break.

University of Minnesota researchers flex the mind's muscle, steer CG choppers

Joseph Volpe — Thu, 27 Oct 2011 16:59:00 -0400

You've undoubtedly been told countless times by cheerleading elders that anything's possible if you put your mind to it. Turns out, those sagacious folks were spot on, although we're pretty sure this pioneering research isn't what they'd intended. A trio of biomedical engineers at the University of Minnesota have taken the realm of brain-computer interfaces a huge leap forward with a non-invasive control system -- so, no messy drills boring into skulls here. The group's innovative BCI meshes man's mental might with silicon whizzery to read and interpret sensorimotor rhythms (brain waves associated with motor control) via an electroencephalography measuring cap. By mapping these SMRs to a virtual helicopter's forward-backward and left to right movements, subjects were able to achieve "fast, accurate and continuous" three-dimensional control of the CG aircraft. The so scifi-it-borders-on-psychic tech could one day help amputees control synthetic limbs, or less nobly, helps us mentally manipulate 3D avatars. So, the future of gaming and locomotion looks to be secure, but we all know where this should really be headed -- defense tactics for the Robot Apocalypse.

New phase-changing alloy turns waste heat into green energy, exhibits spontaneous magnetism (video)

Christopher Trout — Sat, 25 Jun 2011 08:13:00 -0400

Looks like harvesting waste heat is all the rage in 2011. Yet another team of researchers -- this time at the University of Minnesota -- has found a way to harness energy from our hot castoffs. The group has apparently created a brand spanking new alloy that spontaneously creates energy when its temperature is raised by a small amount. Future uses for the material, known as Ni₄₅Co₅Mn₄₀Sn₁₀, include charging a hybrid car's battery with the help of waste heat from its exhaust. So what's the trick? Well, this wonder material is a phase changer, meaning it can go from non-magnetic to magnetic in moments, when the temperature rises. When that happens, the alloy absorbs heat, and bam! You've got electricity. The team is also collaborating with chemical engineers to create a thin film version of the material that could be used to convert waste heat from computers. If phase changing gets you all hot and bothered, check out a video demonstration of the alloy's sudden magnetism after the break.

Amphibious Aquapod might be the clumsiest robot ever (video)

Amar Toor — Thu, 26 May 2011 08:48:00 -0400

It may look like nothing more than a random piece of seaside trash, but that ugly little creature you're staring at is actually known as Aquapod -- an amphibious robot that crawls around by falling over itself. Literally. Developed by researchers at the University of Minnesota's Center for Distributed Robotics, Aquapod uses two carbon fiber arms and a servo motor system to somersault itself around, like an inebriated horseshoe crab. It's certainly not the swiftest of bots, but this guy's durable enough to move across rough terrains and, per its nickname, is completely waterproof and in full control of its buoyancy. Creators Andrew Carlson and Nikos Papanikolopoulos say their $2,000 brainchild could one day be used to monitor fish populations and conduct underwater experiments -- or to simply scare the bejesus out of beach-going children.

Rolling robot learns to fly, plots escape from human captors (video)

Donald Melanson — Mon, 16 May 2011 18:37:00 -0400

Why settle for a robot that can just roll or fly? That's the question some researchers from the University of Minnesota's Center for Distributed Robotics recently asked themselves, and this little transforming contraption is their answer. As you can see in the video above, it's able to roll around on the ground with relative ease (although obstacles may be another matter), and then prop itself up to take flight like any other robotic helicopter. Those thinking about trying their hand at a DIY version may want to think twice, however, as its not exactly as simple as it may appear. In fact, the researchers apparently spent a full $20,000 just to develop the folding rotor mechanism.

Human Connectome Project maps brain's circuitry, produces super trippy graphics

Christopher Trout — Sat, 01 Jan 2011 10:29:00 -0500

A team of researchers at the Human Connectome Project (HCP) have been carving up mice brains like Christmas hams to find out how we store memories, personality traits, and skills -- the slices they're making, though, are 29.4 nanometers thick. The end goal is to run these tiny slices under a microscope, create detailed images of the brain, and then stitch them back together, eventually creating a complete map of the mind, or connectome. The team, comprised of scientists at Harvard, UCLA, University of Minnesota, and Washington University, is still a long way from cutting up a human brain, partially due to storage limitations -- a picture of a one-millimeter cube of mouse brain uses about a petabyte of memory. A human brain would require millions of petabytes, and an indefinite number of years, causing speculation that the payoff isn't worth the effort -- although, we're convinced the HCP wallpaper possibilities are totally worth it.

Self-assembling solar cells built using ancient wisdom, modern technology

Vlad Savov — Fri, 15 Jan 2010 09:14:00 -0500

Alright, so self-assembling electronics are hardly new in and of themselves, and nanoscale tech tends to always come with bombastic promises, but you don't wanna miss how this latest innovation is built. Two professors from the University of Minnesota have successfully demonstrated a self-assembly technique that arranges microscopic electronic elements in their proper order thanks to the absolute enmity that exists between water and oil. By coating elements with a hydrophilic layer on one side and some hypdrophobic goo on the other, they've achieved the proper element orientation, and the final step in their work was the insertion of a pre-drilled, pre-soldered sheet, which picks up each element while being slowly drawn out of the liquid non-mixture. The achievement here is in finding the perfect densities of water and oil to make the magic happen, and a working device of 64,000 elements has been shown off -- taking only three minutes to put together. If the method's future proves successful, we'll all be using electronics built on flexible, plastic, metal, or otherwise unconventional substrates sometime soon.

University of Minnesota orders up 108- by 48-foot HD scoreboard from Daktronics

Richard Lawler — Tue, 04 Mar 2008 14:22:00 -0500

The University of Minnesota has finally found a way to one-up OSU and the other U of M's football squads by ordering up the first Daktronics HD-16 scoreboard in the Big Ten (Will you be able to watch the Big Ten Network on it?). Second-largest in college football to Texas' Godzillatron, the 108- by 48-foot display takes advantage of all the company's latest technologies, and should be ready for Minnesota's home opener against Air Force in 2009. Some fans may wonder how the big screen will make the football team better, but if top-notch facilities help recruit the next Marion Barber III-Laurence Maroney connection then it should be well worth it.
