UCLA creates portable microscope that uses holograms, not lenses

Instead of lugging a heavy microscope into the field, doctors and nurses in remote regions may have a more portable choice — a lightweight microscope that replaces lenses with holograms. Researchers at UCLA announced a prototype dual-mode microscope that’s lightweight, costs between $50 and $100 to produce and is similar in size to a banana. Like a hologram that uses interfering rays to create an image, this device shines light on a sample where its sensor chip (apparently also found in iPhones and BlackBerrys) and a cloud-based software program analyze the interference pattern and reconstruct an image of the sample. Since it’s dual-mode, both large samples and small samples can be analyzed through processes called “transmission” and “reflection,” and doctors could potentially use their laptops or smartphones to access the images remotely. Although still considered a prototype, researchers think the development has the opportunity to revolutionize health care by allowing doctors to test things like water, blood and food. Check out the full PR after the break.

Eyeborg filmmaker fires up eye-cam to document cutting edge prosthetics (video)

Eyeborg

In late 2008 filmmaker Rob Spence, caught our attention when he announced his plan to jam a video camera in his skull to replace an eye he lost to an unfortunate accident. Instead of connecting the camera to his brain, Spence sought to become a so-called “lifecaster,” recording the feed on an external device. Now his bionic eye is up and running, and he’s even partnered with a little company called Square Enix to create a documentary about state-of-the-art prosthetics and cybernetics. The short film, embedded after the break, was commissioned to celebrate the launch of Deus Ex: Human Revolution. But, this isn’t just some over-long commercial for a game, it’s a serious exploration of cutting edge leg, arm, and eye replacement technology. Check it out below, but be warned — there are a few image that might not sit well with weaker stomachs.

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.

Robot skin captures super detailed 3D surface images

Remember those awesome pin art toys where you could press your hand (or face) into the pins to leaving a lasting impression? Researchers at MIT have taken the idea one (or two) steps further with “GelSight,” a hunk of synthetic rubber that creates a detailed computer visualized image of whatever surface you press it against. It works as such: push the reflective side of the gummy against an object (they chose a chicken feather and a $20 bill) and the camera on the other end will capture a 3-D image of the microscopic surface structure. Originally designed as robot “skin,” researchers realized the tool could be used in applications from criminal forensics (think bullets and fingerprints) to dermatology. The Coke can-sized machine is so sensitive, it can capture surface subtleties as small as one by two micrometer in surface — finally solving the mystery of who stole the cookies from the cookie jar. (Hint: we know it was you Velvet Sledgehammer).

Tiny RFID amulet stores medical records, makes paramedics’ lives easier

Medical RFIDUsing RFID to store medical records, ultimately making the jobs of paramedics and doctors that much easier, is hardly a new concept. But, for the most part, such devices have been limited to clinical trials. Asahi Kasei Corp. is hoping to change that with the debut of a tiny, 3cm-square charm that can be read by a computer or smartphone. In addition to basic info, such as name, birth date, and blood type, the chip could transmit links to more storage-intensive data like X-rays images. Instead of building out a proprietary system, the company is relying on established technology called FeliCa from Sony. That means the device will enjoy broad compatibility with existing products, and should be inexpensive to produce. Asahi Kasei hopes to begin selling the medical amulets to cities and hospitals within a year, for as little as ¥2,000 (around $25).

$1 chip tests for HIV in 15 minutes flat, fits in your wallet

Getting tested for STDs used to mean a doctor’s visit, vials of blood, and days, weeks, or even months of anxiously waiting for results. mChip aims to change all that, while simultaneously ridding your brain of viable excuses not to get tested. It works as such: one drop of blood goes on the microfluidics-based optical chip, 15 minutes pass, and boom, the AmEx-sized device will confirm whether or not you have syphilis and / or HIV. The bantam gizmo is practically foolproof, as reading the results doesn’t require any human interpretation whatsoever. Plus, it’s cheap — cheaper than a coffee at Starbucks. One dollar cheap. Researchers at Columbia University claim the mChip has a 100 percent detection rate, although there’s a four to six percent chance of getting a false positive — a stat similar to traditional lab tests. As you’d likely expect, there’s hope that the inexpensive mChip will help testing efforts in places like Africa to detect HIV before it turns into AIDS. Next stop: the self-service pharmacy at CVS?

RIBA-II healthcare robot now stronger, smarter — still a bear

RIKEN’s original RIBA healthcare robot was already fairly adept at lifting patients while not completely terrifying them but, as is the case with such things, it’s now been succeeded by a new and improved model. While its outward, bear-like appearance hasn’t changed, the new bot boasts a series of upgrades that now lets it bend over and lift patients up directly off the floor, not just off a bed or wheelchair. It’s also now able to lift patients that weight up to 176 pounds (41 pounds more than before), and it packs an array of new sensors that let it more accurately gauge a person’s weight and carry them more comfortably — not to mention some touchscreen controls on its back for when it needs a bit of direction. Hit the source link below for a video.

Scientists find less damaging defibrillation method, heart tissue relieved

Good news, aging Earthlings: a team of researchers have found a way to shock a coding patient’s heart, while leaving other organs and tissues undamaged from the defibrillator. The device send a single high voltage pulse of electrical energy to a patient’s chest in order to fix an irregular or nonexistent heart beat; traditionally, what often results is damage to point of contact and surrounding skin cells, muscles and tissues, but a team of whiz kids have seemingly figured out a way to dodge the dreadfulness.

Led by scientists Stefan Luther and Flavio Fenton, the team claims that by using a series of five pulses of less potent shocks (instead of a single concentrated charge), docs can see an 84 percent reduction in damaging power. This new technology — coined low-energy antifibrillation pacing (LEAP) — can also be used in implanted defibrillators, not just the well-known flappy paddles. Due to the relatively low emissions, both the patient and such implants have extended lives. And that, friends, is good for us all — given the impending Robot Apocalypse, we’ll be needing those extra years just to hold down the fort.

Samsung study finds no link between cancer and work conditions, might not be released in full

Samsung has finally wrapped up that investigation into alleged cancer risks at its chip facilities, but it might not share the details with the rest of the world. In the study, which the company commissioned last year, researchers from US-based Environ International Corp. found that cancers affecting six semiconductor employees were unrelated to any chemicals they may have been exposed to on the job. Of those six workers, four have already died and five of the families are currently pressing charges. Last month, a South Korea court determined that two of the cases could be linked to toxic chemical exposure — a ruling that Environ’s report clearly contradicts. Samsung, however, is reluctant to disclose the results in full, for fear that doing so may reveal some proprietary information. Environ’s Paul Harper declined to say how much Samsung paid for the investigation, due to client confidentiality, while confirming that the research was carried out in consultation with a panel of independent experts. Semiconductor exec Kwon Oh-hyun, meanwhile, denied that the company commissioned the study in order to use it as evidence in the ongoing court case, in which Samsung isn’t even listed as a defendant.
