Scientists created living robots out of stem cells
Scientists have created a new life form that's something between a frog and a robot. Using stem cells scraped from frog embryos, researchers from the University of Vermont (UVM) and Tufts University assembled "xenobots." The millimeter-wide blobs act like living, self-healing robots. They can walk, swim and work cooperatively. Refined, they could be used inside the human body to reprogram tumors, deliver drugs or scrape plaque out of arteries.
Scientists build logic gates out of gut bacteria, then hopefully wash their hands
Ever thought about upgrading your PC by breeding more cores? Or planting a few GBs of extra storage out in the yard? Us neither, until we heard that scientists at Imperial College in London have succeeded in building "some of the basic components of digital devices" out of genetically modified E.Coli. We've seen these germs exploited in a similar way before, but Imperial's researchers claim they're the first to make bacterial logic gates that can be fitted together to form more complex gates and potentially whole biological processors. Aside from our strange upgrade fantasies, such processors could one day be implanted into living bodies -- to weed out cancer cells, clean arteries and deliver medication exactly where it's needed. So much for Activia.
Carnegie Mellon researchers develop world's smallest biological fuel cell
Cars and other vehicles may be the first thing that springs to mind at the mention of fuel cells, but the technology can of course also be used for plenty of other devices big and small, and a team of researchers at Carnegie Mellon University are now looking to take them to a few new places that haven't been possible so far. To that end, they've developed what they claim is the world's smallest biological fuel cell, which is the size of a single human hair and "generates energy from the metabolism of bacteria on thin gold plates in micro-manufactured channels." That, they say, could make it ideal for use in places like deep ocean environments where batteries are impractical -- or possibly in electronic devices with some further refinements, where they could potentially store more energy than traditional batteries in the same space. The university's full press release is after the break.
City of Heroes launches the Mutant Super Booster
With all the characters growing organic spines and shooting bio-electricity at foes, the new City of Heroes Mutant Super Booster seems like an addition that the game has long been awaiting. While yesterday saw a giveaway for several codes by the Paragon Studios team, today is the official launch where everyone can enjoy the new costumes, emotes, and bonus power. The first is the most eye-catching of the setup, naturally, and we've included a gallery of both the in-game art and concept art for the new Bioluminescent and Organic Armor costume sets. New costume change emotes are also par for the course, with this booster adding a triad that includes the supremely freaky Rapid Boil emote. (The Facebook video does it justice in both accuracy and freakiness.) Last but not least is the new innate power Secondary Mutation, which allows you to unleash the latent power of your DNA for a random effect, usually involving self-buffs of varying duration. City of Heroes players will find plenty to enjoy with the newest booster, so check out the gallery and start boiling yourself a new costume. %Gallery-96158%
DNA computer solves logical problems, inches closer to practical use
The world of biomolecular computing is hardly a lonely place: bacteria, enzymes, and all manner of chemicals have already been used to perform basic automated tasks. DNA computers are arguably the most advanced organic form of "autonomous programmable computing devices," with one already boasting a pretty tight game of Tic-Tac-Toe. The latest, put together by the Israeli Weizmann Institute, advances things with its ability to correctly respond to problems of logic. By feeding molecular rules and facts into the system, the researchers are able to program DNA strands to produce yes and no answers to basic questions. Programming is said to be technically identical to that used in electronic devices, with a robot compiler converting the programming language into molecular-level information. The ultimate aim of the project is to produce miniscule disease-fighting bots that can battle infections within the human body -- provided the DNA-programming drones don't go all Yul Brynner on us.[Thanks, Karl]
Leaping robots could embark on interplanetary exploration
Just as ASTRO and NextSat get ready for decommissioning, a duo of lightweight leapers are getting geared up to take the proverbial next step from testing to interplanetary exploration. Jollbot and Glumper, crafted by a group of mechanical engineers from the University of Bath, could provide solutions to "traveling across rough terrain, such as climbing stairs and jumping fences, that normally create obstacles for wheeled and walking robots." The machines utilize biologically inspired mechanisms that enable them to clear heights of up to 1.17-meters and capriole forward about two-meters at a time. Researchers are hoping to equip the devices with solar panels in order to keep them juiced up and ready to pounce at a moment's notice (you know, in case a stray asteroid comes zipping in), but there's been no plans made yet to get devices such as these launched into orbit.
SeaAway's offshore Sea Sentinels detect incoming contraband
A Florida-based startup dubbed SeaAway (no relation to Segway, truth be told) is looking to make our ports a good bit safer in the future by implementing an offshore screening process that could detect "chemical, biological, and nuclear traces as ships travel through." The aptly-dubbed Sea Sentinels would be anchored to the seafloor some 14-miles from a port, and will even house up to 15 humans and an array of unmanned aerial vehicles for extreme situations. The platforms would utilize RFID readers to detect what types of cargo passed through its screen, and if sensors flag a suspicious container, the Coast Guard is called into action. Unfortunately, the $100 million it costs to erect each system would have to be subsidized by a passage fee of $20 per container, but tax breaks for shippers are currently be pondered. Nevertheless, a prototype system will see construction later this summer, and if all goes well, finalized versions could be patrolling our seas in the not too distant future.
Oculus' uber-oxidised water hastens healing
We've seen self-assembling chips, self-healing panels, and even regenerative houses hit the drawing board before, but California-based Oculus has created a liquid that can reportedly quicken the healing process when recovering from wounds. The firm's Dermacyn topical wound care is an "oxychlorine formulation" using the company's own Microcyn concoction, which is made by "taking purified water and passing it through a semi-permeable sodium chloride membrane to produce the oxychlorine ions," and essentially contains "electrically charged molecules which pierce the cell walls of free-living microbes." The formula is reportedly successful in killing off virii, bacteria, and fungi, and currently, the company is enrolling patients in a Phase II trial to evaluate its effectiveness in treating diabetic foot infections. The company is hoping to start said trial in Q3 of this year, and if all goes well, wants to execute a pair of larger Phase III trials shortly thereafter.[Via BBC]
Nuke detectors could eventually reside in your cellphone
Just in case fixed sensors all across the country, bomb-sniffing bees, and Bay Area nuke detectors weren't enough to make you rest easy, Homeland Security is cookin' up another safeguard at the expense of privacy. Reportedly, the Department is looking into the idea of "outfitting cellphones with tiny, sensitive detectors that would alert the government and emergency responders to the presence of radiological isotopes, toxic chemicals, and deadly biological agents." Essentially, future mobiles could come pre-loaded with such a device that continuously monitors said chemicals and sends off alerts via GPS if anything goes awry. Of course, officials are expecting "quite a few hurdles" along the way, one of which will be battling the privacy advocates who don't understand that their handset probably already contains the technology for Big Brother to see everywhere they go. No word on when these plans could take effect, nor whether older phones will be retrofitted with the toxic sensors, but we can already envision quite a few false alarms care of the cellphone-totin' chemists in the crowd.

USC researcher crafting silicon brain cells
C'mon, linking actual brain cells to a silicon chip might sound a bit sensational at first, but considering the work that's already been done on replacement retinas and human brains, Ted Berger's recently-hyped work is pretty much right on time. Essentially, the USC researcher has spent the past decade or so "engineering a brain implant that can re-create thoughts," and moreover, certain implementations could even "remedy everything from Alzheimer's to absent-mindedness." We know, thoughts of instantaneous brilliance are running wild through your mind, and considering that Ted (and his highly-regarded team) have figured out how to link a silicon chip to actual brain cells and elicit responses, the possibilities are indeed nearly endless. Put simply, Berger hopes that brain disorders that are currently battled with intensive drug regimens with less-than-exciting side effects can be solved "by simply implanting a few computerized brain cells." Of course, the team admits that it's "years, maybe decades" away from hospital-approved apparatuses, but if you're interested in reading (a lot) more about "the future of brain science," grab your specs, prepare your paltry short term memory, and hit the read link for all the insight.[Via MedGadget]
Virginia Tech researcher crafting amoeba-inspired robotic helpers
Although we've seen failed attempts at turning amoebas into helpers, Virginia Tech's Dennis Hong is hoping that his creations will see a bit more success. Using funding from the prestigious CAREER grant, the researcher is designing a Whole Skin Locomotion (WSL) mechanism "for robots to work on much the same principle as the pseudopod, or cytoplasmic foot, of the amoeba." The device's primary goal seems to hover around the world of search-and-rescue, as the diminutive crawler can maneuver in and around tight spaces without regard for its own health, and of course, a nearly-microscopic bot just can't be developed without hinting at one day ending up somewhere inside your body. Notably, it appears that Mr. Hong isn't satisfied with just building a prototype, as he's already got plans for implementing the technology into projects such as IMPASS (Intelligent Mobility Platform with Active Spoke System, DARwin (Dynamic Anthropomorphic Robot with Intelligence), and STriDER (Self-Excited Tripedal Dynamic Experimental Robot).[Via MedGadget]
Robotic tuatara fools males, partakes in social dominance study
Although Wowwee's farm of robotic animals are quite the playful bunch, they aren't exactly prime targets for participating in a biological study of how animals interact in the wild, but Jennifer Moore from Victoria's School of Biological Science is aiming to use a faux tuatara to be the focal point of a new study. Modeled after a highly-regarded and recently deceased tuatara named Oliver, the new creature will purportedly be mingling with others of its kind in order to give a first-hand view on "social dominance and aggression in wild tuatara." Crafted by the Weta Workshop, Robotic Oliver will be used for the first time next month on the tuatara capital of the world, Stephens Island, in order to carefully inspect male mating habits in an effort to "significantly enhance conservation efforts." Of course, utilizing robotic clones for the betterment of a species seems like a brilliant idea, but we should probably all join in unison and hope this same stunt isn't pulled on the human population.[Via RobotGossip]
Colorado researchers edging closer to tabletop X-rays
Although improvements on the typical X-ray are being made quite frequently of late, a team of researchers at the University of Colorado at Boulder is hoping to make a huge leap forward in the way we're forced to handle these traditionally burdensome machines. In an effort to reduce the size required to install and utilize your average X-ray machine, the crew has purportedly developed a new technique to "generate laser-like X-ray beams" that avoid the existing need for such a "monstrous power source." The end goal is, of course, a tabletop device that can handle uber-high resolution imaging at a fraction of the cost and size of current units. It all starts by using "a powerful laser to pluck an electron from an atom of argon and then slam it back into the same atom," which then bypasses the typical problem of X-ray waves "not marching in step" by sending "weak pulses of visible laser light into the gas in the opposite direction of the laser beam generating the X-rays." The feeble beam reportedly "manipulates the electrons plucked from the argon atoms" in order to perfectly intensify the strength of the process by "over a hundred times." Essentially, the researchers have devised a more controlled way to perfect the timing of X-ray blasts, and are utilizing light to focus the process rather than using gobs of energy as it hopes enough undirected beams strike the intended area. Per usual, we've no idea just how close this idea is to becoming ready for the commercial world, but considering all the competition that's currently out there, we don't envision these Buffs wasting any precious time.
Leg spines set to give robots better footing
Just what we need: an invention to make the robotic armies that will one day surely turn against their creators better scramblers. Regardless of future impact, researchers at the University of California and Pennsylvania University are envisioning "leg spines" that would allow robotic creatures resembling insects and spiders to scramble across gap-ridden surfaces much better than they currently can. The scientists carefully watched slow-motion footage of arachnids dashing across wire mesh and noticed just a 22-percent slow down from running across solid ground. Apparently, the little buggers are able to distribute their weight just so across their myriad of legs, so that there's usually one leg that catches another's fall and prevents the creature from getting too caught up. This biological method is being applied to robotic limbs, assisting crawling creatures to make it across less-than-ideal conditions by utilizing mechanical feedback. Look, we're down with eight-legged freaks, we're just not so fond of these things possessing an inhuman ability to track us down should a case of mutiny sweep the robotic world.
Researchers craft microscale robotic hand for surgeries
It's no surprise that humans are doing less and less of the dirty work while they simply control robotic creatures that are actually doing the internal repairs, but a UCLA researcher has devised a ridiculously tiny "microhand" to handle even the smallest surgery-related tasks. The hand, which is said to be a "feat of microscale mechanical systems (MEMS)," measures just one millimeter across when closed into a fist, features four "fingers" made of six silicon wafers each, and touts four gas-powered balloons acting as the muscles at the wafers' joints. As you may expect, the gas lines that run to the balloons inflate and deflate the joints, causing the fingers to grasp and release as needed. The primary purpose is to eventually use the technology in new forms of "minimally invasive surgery," and although the microhand is likely years away from practical use, they're already in cahoots with robotic firm to develop a "slightly larger" rendition with an onboard camera for live action video feeds.[Via MedGadget]
