GE researchers invent a 7-dimensional heart scanner
While conventional MRI scans can produce highly detailed images of our internal organs, the process can take up to 45 minutes -- not the sort of delay you want when suffering from a heart attack. However, a new scanning technology from GE promises to cut that time by up to 30 minutes and deliver near-real time videos of the heart in unprecedented detail.

It's already inside an Aston Martin racing car but the company's goal is to get it into mainstream consumer cars within a few years. Meanwhile Cornell scientists invented a polymer that has pores and can pump fluids, allowing it to act as an artificial foam heart. And a Tokyo-based eyewear company will begin selling its smart glasses next month. The classically-styled eyeglasses can track movement and are definitely less nerd-defining than the telltale Google Glass version.
Scientists make an artificial heart out of foam
Artificial hearts only kinda-sorta behave like the real thing. They pump blood, sure, but they're typically solid blocks of machinery that are out of place in a squishy human body. Cornell University thinks it can do better, though: its scientists have developed an artificial foam heart that imitates both the functions and shape of its fleshy counterpart. The key is a new polymer that can be poured into specific shapes, and has pores that let it pump fluids. It's not only soft and stretchable, but more efficient -- you don't need much energy to get liquids moving.
UV-light enabled catheter fixes heart defects without surgery
Advances in medicine are treating patients in ways that were never thought possible. The latest breakthrough comes from a team of scientists in Boston who have developed a way to fix holes in the heart without the need for invasive surgery. They created a ground-breaking catheter, biodegradable glue and patch that fit inside the patient's veins and are guided directly into the heart. Once there, it uses a reflective balloon and UV light to apply the patch and activate its adhesive coating.
MRI scans used to create 3D-printed hearts for surgery practice
Heart surgeries could be so much safer if surgeons can see and feel an actual representation of the patient's organ before the procedure itself. A system developed by a group of researchers from MIT and Boston Children's Hospital might make that a viable option. By using MRI scans as a blueprint, it allows doctors to print out a model of the patient's heart within just three hours. When you do an MRI scan, the machine takes hundreds of cross-sectional images of your organs. In order to create an accurate 3D-printable model, though, the boundaries between each part of the organ must be determined. It's critical for each part to look distinct, especially if the patient needs surgery due to an unusual anatomy.
Cardiovascular health app is the UK's first ResearchKit project
One of the first health apps built with Apple's ResearchKit platform is now available to download outside the US. MyHeart Counts, which was first announced at Apple's "Spring Forward" event in March, has been opened up to iPhone users in the UK and Hong Kong for the first time. Once you've opted in, you'll be asked every few months to take part in a weeklong test, which includes seven days of activity monitoring, a 6-minute walk and a submission of personal risk-factor information. Stanford University will offer a review of your heart's health in return, as well as some advice for improving general wellness, but the idea here is to make it as easy as possible to become a volunteer. ResearchKit was, after all, invented to help scientists and medical professionals conduct large-scale studies. There are over one billion iOS devices in the world, so if even a fraction of those take some time to use the app, that's a trove of new information that will benefit medical research.
Heartbeat chip tests medicine based on your natural rhythms
Scientists can simulate organs on chips when testing medicine, but mimicking your natural rhythm is another matter -- it's hard to know if those drugs will behave properly under the stresses of your body. That won't be a problem when the University of Michigan's newly developed testing chip comes into play. The device uses microscopic, gravity-powered fluid channels to replicate heartbeats and other natural flows (such as brain signals) when testing chemicals. You'll know if that treatment works properly when the patient's heart is racing, for example. And unlike previous attempts at emulating heartbeats, you don't need to stick around pumping fluid yourself -- you can conduct long-term tests that reflect what would happen in a real body over time.
This transforming phone is all heart, no brains
In Japan, people still use feature phones. But despite the smartphone revolution, dumb phone innovation is not dead. Not when a phone can magically, (Transformer-ly) convert from a heart shape into something approaching a chubby handset you can actually talk into. Imaginatively titled "Heart", it'll come to Nihon in both red and black options, and according to our Japan team, weighs a mere 54 grams. Curiously, it doesn't launch until after Valentines' Day (late March), but when it does arrive, the phone will also come with in a special Sailor Moon iteration, with magical wand dangly accessory and livery.
Google Glass can tell if you're stressed
It's not always easy to tell when your stress levels are through the roof, and you may not always want to break out a heart rate sensor just to find out when it's time to relax. You might not have to, if researchers at Georgia Tech and MIT have their way; they've developed BioGlass, an Android app that uses Google Glass to determine how frazzled you are. The software measures your heart and breathing rates by checking for tiny movements picked up by Glass' accelerometer, gyroscope and front-facing camera. In theory, you'd only have to wear the smart eyepiece to know when it's time to calm down.
Inhabitat's Week in Green: SuperPier, reversing the aging process and an artificial, self-regulating heart
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Well folks, we've made it through two major holidays, with just one more to go. We can't look into a crystal ball to see what 2014 has in store for us, but looking into Rawlemon's Betaray prototype might be the next best thing: It's a giant transparent marble capable of concentrating solar energy 10,000 times. If hanging out with all those nieces and nephews over the holidays has you feeling your age, you'll be thrilled to know that Harvard scientists have successfully reversed the aging process in a group of laboratory mice. And if you're already bored with typical 3D printing news, here's something new: Boots Industries just developed a new 3D printer that's capable of replicating itself.
Nymi bracelet uses biometric heart data to unlock digital and physical doors (video)
Unlike faces and fingerprints, a heart's electrical activity is difficult to fake -- it's a unique and potentially ideal security tool. Bionym is taking advantage of this trustworthiness in its upcoming Nymi bracelet. The wristwear authenticates users through a combination of electrocardiograms and Bluetooth proximity detection; if Nymi recognizes your heart rhythm, it automatically logs you into nearby devices. The bracelet also recognizes gesture commands, and a future developer kit should extend the gadget's usefulness beyond basic security for PCs and smartphones. It could unlock doors or make retail payments, for example. Nymi won't ship until early 2014, but it's already available for pre-order at a $79 early bird price.

The man, woman, or one-eyed Gnome of your dreams might just stumble over you on this fine day! Read on as we sum up some of the larger Valentine's events in MMOs today.
Stanford researchers make heart implant powered by radio waves, put batteries out of a job
Batteries used to be the only way to power implantable gadgets, but additional surgeries are needed to replace the power packs once their juice runs out -- a less-than-ideal solution for patients. Recent discoveries, however, have such medgadgets being powered by photons, hip hop and now high-frequency radio waves. Electrical engineers at Stanford built a cardiac device that uses a combination of inductive and radiative transmission of power, at about 1.7 billion cycles per second, to its coiled receiving antenna. Previous prevailing opinion held that the high frequencies needed for wireless power delivery couldn't penetrate the human body deep enough, and the lower frequencies that would do the trick require antennas too large to work as implants. That conundrum was solved by getting the high-frequency signals to penetrate deeper using alternating waves of electric and magnetic fields. That allowed a 10x increase in power delivery -- up to 50 microwatts to a millimeter radius antenna coil -- to an implant five centimeters below the skin. That antenna also was also designed to pull power regardless of its orientation, making it ideal for applications inside always-moving human bodies. Of course, the implant's really just a proof-of-concept at this stage, but hopefully it won't be long before battery powered implants go the way of the dodo TouchPad.
Prototype heart monitor collar could let sheep text their shepherd, tattle on creeping wolves
It's easy to imagine the lonely Swiss shepherd casually texting his pals during a long day in the field, but reading an SMS from his flock? More possible then you might think. A recent trial in Switzerland outfitted 10 sheep with heart monitoring collars and submitted them to a simulated wolf attack, causing their heart rate to jump from 60 / 80 BPM to 225. The team behind the experiment hope to pair the significant change in heart rate with a future device that releases a predator deterrent while simultaneously sending a text message to the local shepherd. Complete prototypes are being prepped for a 2013 trial in Switzerland and France, where wolf attacks are on the rise. The devices hopes to offer owners of smaller flocks an affordable alternative to keeping a sheepdog. [Image credit: Shutterstock]
Researchers develop cell spray to repair hearts, healthy dose of electricity included
Spray-on solutions have found a place in green technology and even in transmitting radio waves, and they're no strangers to medical research, either. Researchers at the British Heart Foundation are working on a bioelectric spray composed of heart cells to help mend that most vital of organs. Because the cells need to be extremely thin to form a sheet of heart tissue, they are passed through a conductive needle that charges them with up to 30,000 volts. Exposing the cells to an electric field turns the solution into small droplets, which in turn form the cardiac sheet. The scientists can also add other types of cells to create "three-dimensional" tissue, which can be grafted onto injured hearts or sprayed onto scar tissue to help patients' tickers pump more strongly. As is so often the case, the next step will be testing the technology on animals, and the project's ultimate goal is to use this spray-on solution rather than making patients wait for donor hearts.
Fake jellyfish made from rat cells have a place in our hearts (video)
There's a whole sea of jellyfish out there ready to sting indiscriminately. So, why do we keep trying to make them? Scientists from Harvard and Caltech have a pretty good reason for creating fake jellies -- they hope to mend broken hearts by adapting their 'pumping' style of movement. Much like our own vital organ, the creatures are a mass of muscle adept at shifting fluid, meaning the research has several medical applications, such as bioengineered pacemakers for busted tickers. In creating the Medusoids, the team used a silicon scaffold coated in functional rat cardiac tissue, copying the muscle layout of a real jellyfish as best they could. When immersed in salt water and treated to bursts of current, the cells contract and cause the silicon sheet to move in a way eerily similar to the real thing. Next step for the team? An autonomous version that can move and potentially feed without their influence, of course. And, after seeing the little swimmers in action, we've certainly got palpitations. See what we mean after the break.
Heartbeat visualizer lets your ticker power a light show (video)
It may look like something that'd be at home in iTunes, but this visualizer developed by NYU student Phan V is linked to something even more unique to you than your music collection. With the aid of a mic'd up stethoscope, it's able to visualize a person's heartbeat in a manner that has quite a bit more punch than the usual means -- the person's pulse rate determines the speed of the animation, while the volume of the heartbeat captured determines the brightness. Practical? Maybe not, but you can check it out in action in the video after the break.

DARPA to develop biometric sensor capable of seeing through walls, pulling your heartstrings
The feds may soon know the way to your heart. Literally. Earlier this month, the forward-thinkers over at DARPA announced plans to develop new technologies capable of identifying human life through walls. The program, known as "Biometrics-at-a-distance," would essentially combine two pre-existing Pentagon projects: the Radar Scope, a device that can see through walls, and 2009's LifeReader, a system that uses Doppler radar to detect heartbeats. Though the military already employs a handful of devices to help soldiers see humans from behind walls, DARPA apparently thinks there's room for improvement. Most contemporary technologies, for example, only work from a maximum distance of eight meters, and aren't as accurate within more densely populated areas. DARPA wants its next project to extend this range beyond ten meters, while sharpening its ability to penetrate thicker obstructions. The agency also wants its sensor to identify individual humans using electrocardiography, which traces the heart's electrical activity. According to DARPA, this could allow users to pinpoint up to ten people at the same time, which could pay dividends during disaster rescue efforts, military operations, or your next Eyes Wide Shut party.
Oregon Scientific trots out Gaiam Touch button-free heart rate monitors
They're being hailed as the first button-free, touch screen heart rate monitors, with Oregon Scientific and Gaiam teaming up to produce the wearable SE338M and SE336. According to the companies, these things are a scant two millimeters thinner than any competing product on the market, and they've even captured an International CES Innovations 2012 Design and Engineering Award in the Health & Wellness category. Looking more like a watch than a fitness / health tool, the Touch line supports both wrist and chest-worn options, utilizing ECG technology that requires but a single touch of the finger on the monitor's sensor for an accurate heart rate reading. For those eying the strap model, that one operates in digital and analog modes and tracks fat burned, though the strap-free model will also track calories burned and heart rate data. Predictably, you'll also find a stopwatch, zone alarm, clock and calendar, and those itching to find a stocking stuffer this early can plop down $99.99 to $109.99 right now at the Oregon Scientific Online Store, Target, Sports Authority, Academy Sports, MC Sports and Athleta.
