Watch out, battery-powered MAVs -- your viability could be seriously in danger. Based on a patent application from University of Florida aerospace engineer Subrata Roy, he's reckoning that a micro air vehicle could be propelled by plasma. Scientists have known that passing a current or magnetic field through a conducting fluid generates a force, but exploiting it for use in moving an aircraft has proven futile thus far. The phenomenon, simply known as magnetohydrodynamics, has typically been tested on larger crafts, but Mr. Roy's invention would boast a wingspan of less than 15-centimeters and resemble a flying saucer more so than a 747. Of course, this fantastic idea has yet to become much more than just that, but for armed forces and entities obsessed with surveillance, this could undoubtedly be big.

From what we've seen, the British military is pretty savvy on its robotics. Apparently mechanical beings aren't integrated enough, however, as the British Ministry of Defense has launched its first ever Grand Challenge, which "encourages participants to turn their ideas into prototypes for machines the army can use in urban environments." The six finalists that were chosen each received around $600,000 in order to construct their contraptions, and this August, we'll see an unmanned buggy that can analyze a gunman's movements, a self-propelled, remote-controlled camera and minuscule helicopters used for reconnaissance missions. Best of all, these creations won't just be propped up on some shiny display -- oh no, they'll be taking part in a mock battle in Copehill Down, with even more loot and an enviable trophy on the line.

Rolling around jacking up innocents and tossing Molotov cocktails is pretty enthralling on your vanilla 46-inch HDTV, but can you even imagine the rush of swiping a hot dog, burning out in someone else's whip and then snagging a new pair of kicks on this? Researchers (and gamers, obviously) down at UC San Diego have re-engineered their middleware to enable such masterpieces as this to be played on the big monolithic HIPerSpace screen, and needless to say, we can't imagine much real work getting done with this new functionality coming to light. Head on down to the gallery to see what you're missing -- science, research and 4.0 GPAs are such beautiful things.

Researchers at Osaka University are redefining "thought-controlled" limbs. Hailed as the first endeavor to dabble in the world of bionic phalanges by requiring open-skull surgery, the research is seeking to develop "real-time mind-controlled robotic limbs for the disabled." Of course, it's not the goal that's striking, but the means. Essentially, gurus working on the project are hoping to place electrode sheets directly on the surface of the brain in order to "obtain a more accurate signal," and amazingly enough, they're currently working to sign up willing subjects that are already scheduled to have brain electrodes added to deal with "monitoring epilepsy or other conditions." Maybe the bionic beings really aren't that far off, eh?

Gurus at Purdue University have conjured up a prototype device which, when injected into a tumor, can actually track the "precise dose of radiation received and locate the exact position [of the tumor] during treatment." Currently, the needle-sized device is held within a hermetically sealed glass capillary, contains a miniature radiation dosimeter, operates without batteries and instead relies on "electrical coils placed next to the patient" for activation. As small as the RFID-enabled unit is, engineers are still hoping to create a version that is around the size of a grain of rice, and hopes are to have it in clinical trials in 2010.

Just two months prior, we all stood in awe of the mighty HERCULES laser housed at the University of Michigan. Now, however, those 300 terawatts of power look mighty puny compared to the one petawatt potential claimed by the Texas Petawatt. Hailed as "the highest powered laser in the world" by Todd Ditmire, a physicist at the University of Texas at Austin, the device has the "power output of more than 2,000 times the output of all power plants in the United States," and in case that wasn't impressive enough, it's also "brighter than sunlight on the surface of the sun" -- but alas, only for a tenth of a trillionth of a second. Aside from totally ganking the geeky gloating rights from the Wolverines, the Longhorns will use the laser to study astronomical phenomena in miniature (and probably take over the world in short order).

Think you could keep pace with Cornell's Ranger robot? Just last week, the robot walker set an unofficial world record by trotting nonstop for 45 laps (that's 5.6 miles, for those counting) around the university's Barton Hall running track. After reaching that mark, the creature presumably fell over from battery exhaustion, but the team of creators are investigating to find out the exact reason it finally collapsed. Although Guinness officials weren't involved due to too much "rigmarole," the team has quite a bit to be proud of -- after all, an earlier version of the creature only made it 0.62 miles before calling it a day. Aside from garnering bragging rights, the crew is hoping to use Ranger to better understand the "mechanics of walking," which could be used to improve rehabilitation procedures or even athletic performance.

Believe it or not, this isn't the first time we've seen software created in order to determine whether a subject is drop-dead gorgeous, but scientists at Tel Aviv University have seemingly concocted a program of their own that can "interpret attractiveness in women." Before you ask, the researchers have yet to perfect the art of computing the beauty of males, but they're attributing said omission to the difficulty in "defining" attractiveness in dudes. Nevertheless, the software was purportedly able to reach nearly the same conclusion as humans about how lovely (or not) a hundred different ladies were, as it broke down features like face symmetry, smoothness of the skin and hair color. We're told the development could eventually be used in "plastic and reconstructive surgery and computer visualization programs," but c'mon, this is totally meant to automate the grueling Hot or Not process.

Rest assured, we've witnessed quite a few astounding scientific displays set deep within university research labs, but it'd be mighty hard to cover up the $350,000 monolith residing at the Tufts University School of Engineering. The VisWall, unsurprisingly a product of Visbox, combines twin backscreen projectors and sophisticated software in order to display 3D imagery for DNA junkies and budding surgeons to swoon over. Aside from giving researchers and students alike the ability to investigate chemical structures and cellular makeups more closely, the 8- x 14-foot screen also dabbles in haptics, giving remote holders the ability to "guide the manipulation of virtual scalpels or surgical tweezers onscreen." Sheesh, it's like giving kids a reason to attend class -- imagine that.

We'll go ahead and warn you: if you're hoping to purge your mind of all things science this weekend, this post isn't the one to be reading. For the rest of you knowledge seekers, Arizona State University researcher Wayne Frasch has developed a biosensing nanodevice that could possibly revolutionize health screenings and speed up that grueling airport security process. Put simply (well, as simply as possible), he discovered that the enzyme F1– ATPase can be equipped with an optical probe and "manipulated to emit a signal when it detects a single molecule of target DNA." Currently, a prototype of the DNA detector is already being worked up, but there's no word on when (or if) the device will escape the lab and hit the commercial realm. Still not geeked out? Hit the read link and hold on for dear life.

We've seen self-healing materials and artificial arms, but a team of researchers hailing from UCLA have taken two fabulous ideas and wed them together to create "an artificial muscle that heals itself and generates electricity." Put simply, the contracting / expanding of the material can generate a small electric current, which can be "captured and used to power another expansion or stored in a battery." The scientists have relied on carbon nanotubes as electrodes rather than metal-based films that typically fail after extended usage, and in an ideal world, the research could eventually lead to (more) walking robots and highly advanced prosthetics. Integrate an AC adapter in there and we're sold.

The University of Michigan's COM-BAT most definitely isn't the first mechanical animal to get its inspirations from the bat, but it's probably the best equipped to play a vital role in modern day warfare. A select group of Wolverines have been blessed with a $10 million grant from the US Army in order to concoct a "six-inch robotic spy plane modeled after a bat [that] would gather data from sights, sounds and smells in urban combat zones and transmit information back to a soldier in real time." Purportedly, the critter will eventually boast a bevy of sensors, miniature microphones and detectors for picking up nuclear radiation and poisonous gases. Even more interesting, creators are hoping to implement "energy scavenging," which would enable the bat to stay charged from wind / solar energy along with vibrations and "other sources." So much for being nocturnal, eh?

After this, you'll never have the same mental image when hearing "remote controlled car" again. Ever. Resident engineer and all around madman Dr. James Brighton took a break from his rigorous teaching duties at Cranfield University and whipped up a RC Hummer H3 -- as in, the man converted an actual Hummer H3 into a remotely controlled toy. Amazingly, the conversion was completed in just a month, and it's reportedly able to "climb a 407-millimeter vertical wall, traverse a 40-percent side slope and operate in up to 610-millimeters of water." Hit up the read link for a few more images of this guy having the time of his life.

We've seen initiatives all over the globe created in an attempt to beat blindness, but researchers based at MIT are feeling fairly confident that their development is within a few years of being able to "restore partial sight to people who have slowly gone blind because of degenerative diseases of the retina." The bio-electronic implant, which is about the size of a pencil eraser, would actually sit behind the retina at the back of the eyeball, and images would be transmitted to the brain "via a connector the width of a human hair." As it stands, an FDA grant application is already in the works, and the scientists are hoping to have it implanted in an animal as early as this summer. Still, the solution only works for folks who "were once able to see and have partially intact optic nerve cells" -- those who were blind from birth or suffer from glaucoma are unfortunately ineligible for the procedure.

We'll be honest -- we've seen more snake-like robots than we care to count, but a new creature slithering out of the Norwegian University of Science and Technology is noticeably different than most. As you can see above, there's a distinct lack of treads, tracks or wheels on Aiko, as it actually pushes off foreign objects it encounters in order to creep forward. Additionally, researchers have created a "virtual double" of the critter in order to help guide the development of the actual robot, though we've yet to hear if it plans on joining Anna Konda in war on fire.
