There are literally entire stores devoted to devices that detect drink spiking (okay, maybe not stores), but what about those of us concerned over food-borne pathogens? A crew of European researchers are addressing said worries by "creating one of only two prototype systems in the world that prepare samples and perform DNA tests on bacteria in a portable, easy-to-use and cost-effective chip." Essentially, the EU-funded OptoLabCard project is aiming to concoct a small, disposable laboratory that humans could carry around and use to detect diseases such as campylobacter and salmonella before ingesting contaminated grub. Team members are suggesting that a commercial product could be ready to roll within three years, with prices for each "lab" reaching as low as $0.50. 'Til then, always make your buddy have the first bite.

We've heard that the "gold standard" pen and paper test seems to work fairly well at detecting the earliest stage of Alzheimer's disease, but gurus from Georgia Tech and Emory University have teamed up to develop a much quicker method for accomplishing the same. The ten-minute DETECT test utilizes a head-worn visor with a built-in LCD, headphones and a handheld controller, which the patient interacts with as he / she is put through a series of visual and auditory tests that "assess cognitive abilities relative to age," gauge reaction time and measure memory capabilities. Initial tests have purportedly shown it to have "similar accuracy" to the aforementioned pen and paper test (which takes around 90-minutes to administer), and while we've no idea when the device will be available for public use, its creators have already formed a firm (Zenda Technologies) to commercialize it. Finally, a legitimate use for head-mounted displays -- thought we'd never see the day.

Yeah, we've got HMDs for the visually impaired, but seriously, who's for sporting one of those things just to catch an afternoon soap? Thankfully, Dr. Eli Peli (and colleagues) from Harvard Medical School is lookin' out for said sect, and has developed a method for "enhancing the contrast of images of people and objects of interest on their digital televisions," which, during trials, was found to enhance legibility and overall enjoyment when watching. Furthermore, the technology is said to be the first to play nice with digital TV images, which seems fairly important considering that analog signals have but a few months to live here in America. Purportedly, the all-important modification that made the adjustments possible could be applied to HDTVs and digital STBs in the future, and sure enough, Peli has already sparked up conversation with Analog Devices in order to create a prototype chip for use in forthcoming sets. Now, if only clearing up those Get Smart reruns were this simple...

The world is already well aware of just how potent (and useful) femtosecond lasers are, and a recent study conducted by a team of Arizona State University physicists explains how pulses could be used to dismantle viruses and bacteria without harming a single innocent cell. Rather than follow in the footsteps of indiscriminate laser treatment options, the group of Sun Devils reportedly figured out a way to "produce lethal vibrations in the protein coat of microorganisms," which has the potential to at least treat "blood-borne diseases such as AIDS and Hepatitis." The technique, dubbed ISRS (Impulsive Stimulated Raman Scattering), has shown to not harm healthy human cells while fighting the good fight against viral pathogens, and while there's no easy way to surmise how quickly we'll see this in action, we're gonna wait for a bit more proof before getting our hopes up.

We could almost swear we've heard this same scenario played out in a 80s era sci-fi drama, but apparently, this ain't out of any movie script. By utilizing 14 orbiting satellites and enlisting the assistance of NASA's Applied Sciences Program, scientists are reportedly observing our planet's environment to "help predict and prevent infectious disease outbreaks around the world." Apparently, the satellites collect environmental change data, which is then forwarded on to the Centers for Disease Control and Prevention and the Department of Defense and broken down to estimate and track epidemics. The remote sensing technology is currently be used to target and track malaria (among other things), and NASA surveillance systems can also be used to determine if a given outbreak was caused by "natural circumstances" or if bioterrorism was to blame. Phew, at least we know 28 Days Later won't become an infamous example of life imitating art... right?

While dexterous robots have been helping surgeons in America for some time, Edmonton's Royal Alexandra Hospital is finally getting with the program. Beginning in September, a four-armed surgical robot will be used in procedures to treat prostate cancer, and should provide a much improved in-depth view of the body as well as boosting overall agility while operating. One of the diminutive arms will grasp a camera while the others wield the tools, and trained surgeons will be controlling the action from a three-dimensional screen positioned at a nearby base. Notably, one of the primary reasons Canada has been slower to adopt this type of technology is the price, and while it did cost some $4 million to purchase and retrofit the system into the OR, the shorter recovery time and improved precision whilst operating will certainly prove worthwhile to the average patient.

We've already heard that electricity could cause all sorts of fatal side effects, and it's all but conclusive that stray WiFi can warp your brain, but how come magnetic signals are helping people get their lives back together? If you haven't already guessed, here we have yet another alarmist story which claims that "electrical fields generated by everyday electrical equipment may cause an increased risk of respiratory diseases and infection." The study, published by Imperial scientists, strongly suggests that these toxic fields (some created by computers, no less) can attract airborne particles thanks to stray electrostatic charges, and can then lead to excess amounts of potentially unwholesome deposits making their way into one's lungs. Of course, unless these masterminds wrote their research up via pencil and paper while dressed in ESD suits, we'd say they're just as exposed as the rest of us.

Caring for those with Alzheimer's could be getting a whole lot less stressful, as VeriChip has reportedly doled out 25 VeriMed RFID implantable microchips at the Alzheimer's Community Care 2007 Alzheimer's Educational Conference. Of course, these aren't the first invasive chips that the company has crammed under folks' skin for one reason or another, but these data packin' devices are aiming to provide medical personnel "quick access to identification and medical records information in an emergency situation." Interestingly, not much else was said about future rollouts beyond this small sample trial, but we can't imagine these not showing up en masse (and in humans) once it gets the green light from regulators.

We can't say we'd be first in line to get a dose of Schizophrenia or anything, but Janssen L.P.'s Virtual Hallucinations system shows promise of helping cops, paramedics, and social workers understand a bit more of what the afflicted go through. The technology consists of set of goggles and earphones that envelope you in one of two interactive scenarios that a typical Schizophrenic might face, including being a passenger on a bus in which the other riders continually vanish and reappear while stray birds attempt to invade the inside. The system is reportedly being trialed in a half dozen or so states, and professionals that had made it through the mind warp seem to have a new outlook on respecting and dealing with those with mental illnesses. Of course, if you're just interested in creeping yourself out, there's always easier alternatives.

Although we've seen gait monitors and even prosthetic feet that assist individuals in regaining a more natural stride, scientists at Technion Institute of Technology in Israel have resorted to a head-mounted display for its rendition. This virtual reality device combines "auditory and visual feedback to improve walking speed and stride length in patients suffering from Multiple Sclerosis and Parkinson's disease," and provides the wearer with a "tiled-floor image" that apparently assists them in navigating nearly any terrain. The device is meant to take the place of normal muscle feedback mechanisms, and to provide said feedback to these disabled individuals so they can make adjustments and improve the efficiency of their walk. The HMD has already made its way to several medical centers and has purportedly yielded positive results, but there was no word on when this device would be commercially available.

As the saga continues, we've got yet another flip-flopped story rolling through in regard to the toxicity (or not) of cellphones to our environment. Just under a fortnight ago, a report based on an (admittedly lacking) research study claimed that Colony Collapse Disorder within bees was being encouraged by cellphone radiation. As expected, the researchers began living a life filled with Q&A sessions about the data, and now the "truth" is coming out. Essentially, the scientists are claiming that their data was "misinterpreted," and that the study actually looked at DECT phones and base stations, which transmit a "different frequency than mobiles." Furthermore, another member chimed in and boldly stated that their "studies cannot indicate that electromagnetic radiation is a cause of CCD." So that settles it -- until the next round of bickering begins, of course.

MIT's brainiacs aren't exactly new to the world of partying, and now scientists at the MIT Media Lab have invented a way to "reversibly silence brain cells using pulses of yellow light." The presumably rave-inspired pulsing design offers up the prospect of "controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease," which could theoretically lead to the creation of "optical brain prosthetics to control neurons, eliminating the need for irreversible surgery." Aside from being thrilled that this stuff could help us avoid dodgy robot-led surgeries, it could also help gamers who tend to suffer from epileptic fits when dealing with those head-mounted displays. Additionally, the team is also looking at utilizing the new system to more effectively study neural circuits, but considering that this technology has the ability to "exert exquisite control" over individual neurons within you dome, we certainly hope Big Brother doesn't get ahold of this.

If you see yourself taking an unwanted trip to the ER anytime in the next decade or so, there's a fairly decent chance you'll end up with at least one or two creepy creatures perusing some aspect of your innards. As if mechanical beings cruising through your intestines wasn't eerie enough, a team of Georgia Tech researchers have proposed a new way to constantly monitor one's blood pressure. The aptly-dubbed nanowires take advantage of the "piezoelectric effect in semiconducting zinc oxide" in order to detect minute forces as tiny "as a few piconewtones," or about the same amount needed to unzip a strand of DNA. The specially designed sensors will purportedly enable robotic nurses to continually monitor your blood pressure to take action before things get too out of hand, and of course, the "biocompatible "system would beam results wirelessly to devices in hospitals or even wrist-mounted readers so you'd know when to pop a proverbial chill pill. This should definitely suffice as a "second opinion," eh?

There's already a bevy of devices out there designed to keep track and manage one's diabetes and glucose levels, but Eli Lilly's innocuous pen-like injector looks to make the process of taking insulin a bit less invasive. The Huma-Pen Memoir resembles your average ink pen and shouldn't look too out of place holding it down in your tee's front pocket, but whenever you need a shot of insulin, it conveniently turns into an injector thanks to the hidden hypodermic needle encased within. The device also "allows the user to dial the amount of insulin they need to take," and keeps the dosage, date, and time of the previous 16 shots in order to keep diabetics from overdosing. Users should be able to utilize the same pen for "around three years," and after a needle is used, another is inserted and ready to go at the owners request. A few lucky participants have already received their pen here in the US, and while this nifty invention has been available across Europe for some time now, it will officially hit American retail shelves next week for around $45.

After a long, hard day spent fixing that ever-present paper jam in the office printer, it's nice to kick back in iJoy's ZipConnect while letting the iGoGo personal massager sooth away your aches and pains to the tune of your favorite Breakfast Club jam. But Ntech wants to add one more aspect to your already jubilating experience by tossing an extra vibe directly on your ear. The NVE 100B is an "earring-style" Bluetooth earphone designed to simply clip onto your ear, with the front half pumping out music while the backside thumps to the beat. Strangely enough, the company actually expects the non-intrusive earbud to "prevent possible auditory disease," but we're assuming you take a major hit in sound quality to accomplish such a precaution. Nevertheless, these oddly sensational (albeit probably dysfunctional) earclips should be available on the Korean market just before the year's end for a currently undisclosed price.
