New sensor can read your heart from afar, but knows not your feelings
Are you fed up with your current ECG sensor? Tired of all the mess of electroconductive gels, sticky electrodes and tangled wires? How about this: Britain's Plessey Semiconductors offers an ECG sensor that promises heart-monitoring without the hassle. We've seen similar technology before, but according to the company, the Electric Potential Integrated Circuit -- or EPIC, as it's humbly called -- can read heartbeats even through a sweater; future versions might be embedded in hospital gurneys for constant, unobtrusive monitoring. Like an extremely sensitive voltmeter, it detects tiny changes in electric fields, which means it could also be used for Kinect-style motion interfaces. The company even imagines a future system where firefighters can use the EPIC to find humans in a smoke-filled room. If you're thinking, "My, that sounds just like my Deus Ex dreams" -- hey, we're right there with you.
Cardiograph flatlines on the iPhone and iPad
Cardiograph is a universal app that purports to measure your heart rate via the cameras built into the iPhone or iPad 2. The app has a very slick-looking user interface reminiscent of a real-world electrocardiogram, complete with authentic (and irritating) sound effects, including the always-unnerving sound of a flatline. The app functions similarly to a pulse oximeter, measuring blood flow through a finger placed over the camera and converting that into a pulse rate. Cardiograph has support for multiple profiles and can keep track of multiple users' heart rates over time -- if you can get it to work, that is. Unfortunately, I found Cardiograph was very twitchy about properly measuring my heart rate on the iPhone 4, and it didn't work at all on my iPad 2. On the iPhone, the pulse rate seemed to jump wildly between 100 and 0 beats per minute -- my actual resting heart rate is usually between 45-50 BPM -- while on the iPad 2 Cardiograph insisted it was too dark to obtain a good reading even though I was in a well-lit room and holding my finger right in front of a light. Given Cardiograph's visual polish, it's unfortunate that the basic function the app is supposed to fulfill works so poorly. It's not as though it's impossible for an app like this to work well; I've been successfully using Instant Heart Rate for months. While that app is still less reliable than a chest strap sensor (or even just taking your pulse the old-fashioned way with a finger and a stopwatch), Instant Heart Rate still manages to get an accurate reading much faster and more reliably than Cardiograph. Actual heart rate at time of reading: 50 BPM Cardiograph was just released and has a lot of potential, so hopefully developer MacroPinch can fine-tune the measuring capabilities of Cardiograph and get it to the point where the app is more usable. As it stands now, the 1.0 release of Cardiograph doesn't function well enough for me to recommend it.
Rock Band Weekly: Beastie Boys, Heart, James Brown, Rufus

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.
Ford car seat prototype keeps its sensors on your heart, so you can keep your eyes on the road
Chevy had the whole "Heartbeat of America" thing cornered in the 80s, but now its Ford's turn to get in on the action. The car maker's European research team unveiled a prototype car seat capable of monitoring a driver's heart courtesy of six embedded electrodes, which can take measurements without coming in direct contact with skin. The technology, the latest in a recent string of health-related in-vehicle concepts from the company, can detect whether the driver is having a heart attack and transmit that information to the vehicle's safety system. According to the researchers, the system is already highly accurate in its prototype state, making correct readings for 98 percent of drive time with 95 percent of the drivers tested. For more information on the system, check the video and press release after the break.
Heart Story: One player's quest for iconic affection
The first character I ever made in WoW was a rogue named Lockette. She was an adorable little gnome with green pigtails who I played for 5 minutes while my boyfriend (who'd left himself logged in on the character selection screen) was in the shower. I don't recall much of what I did in the game during those few minutes, but I remember being fascinated by the sight of my character's footsteps on the snowy terrain of Dun Morogh. Looking back on it now, I know it probably sounds like a strange thing to be impressed by, but my gaming experience at that time was limited to sprite RPGs that didn't have those kinds of little details. I wasn't used to being able to affect the environment of a game. So I ran in circles, squiggles, and zigzags, then finally made a small effort at drawing something simple: a heart. That's when I realized the prints fade quite quickly.
Massively's guide to Valentine's Day festivities
Ah spring! 'Tis the time when young men and women's thoughts turn to love -- or at least scoring some nifty holiday-themed loot! This year there's quite a bit going on. Some events are old familiar ones that have stood the test of time. Others offer new twists and things to do for those who have been there, done that. If you aren't feeling the love bug biting, there's even the odd anti-Valentine's-type event, perfect for those who would rather rain destruction down on the head of anyone foolish enough to approach him with anything heart-shaped or pink. Curious as to what's going on? Check out our listing below -- and feel free to chime in if you know of a fun event others should check out! Rip out your Fallen Earth character's heart for Valentine's Day (February 11th-13th) What's better than surviving a nuclear holocaust and wandering your way across a blasted brown landscape rife with societal collapse? Why, sharing said wanderings with someone you love, of course (or at least, someone you lust after in that we've-got-to-do-this-for-the-future-of-mankind sort of way). In a novel spin on the traditional mid-February holiday, Icarus Studios is presenting Fallen Earth's Valentine's Day Massacre event, and clones everywhere can literally offer their hearts as a sign of affection (and a +3 stamina buff). Vindictus spreads the love with new update and holiday (February 1st-15th) Quirky events have quickly become one of Vindictus' staples. Right now players can participate in V-Day events for special rewards. If fishing and chocolate hunting isn't your bag, you can simply purchase a Valentine's Package at the Supply Depot for "sexy Valentine's themed Inner Armor." Cute undies, in other words. Valentine's events will end after the 15th, so players are encouraged to partake sooner rather than regret it later. Time for love in Final Fantasy XI (February 1st-15th) Valentine's Day is almost here, that special time of year when you attempt to distill the essence of a romantic relationship into chocolate form. And if you were hoping to escape from the day within Vana'diel, your efforts are rather misdirected -- Valentione's Day coincides nicely with the holiday in the real world, with just as much saccharine summation of liaisons in Final Fantasy XI.
Fallen Earth serves up a Valentine's Day celebration wasteland-style
People always say that Valentine's Day is just an excuse to sell chocolates and greeting cards, but in Fallen Earth it goes beyond just that. No, the post-apocalyptic game remembers that the core of the holiday should involve giving your heart to someone you love. And since you're not going to be purchasing a heart-shaped box of candy and you've got plenty of spare clones left, you might as well make "giving your heart" a bit more literal, yes? Valentine's Day will see a new mission dubbed "My Bloody Valentine" added to the game for one day only. Successfully completing said mission will give characters a chance to craft their sweethearts a blood-pumping organ complete with a nice +3 Stamina boost. (Although it's not precisely "crafting" when you rip it out of your chest.) So if you're in Fallen Earth during the holiday, let your significant other know the lengths you'll go for a romantic gift.
Heart Spark pendant blinks with your heart, automatically gets you into B.E.D. (video)
Not that we haven't been inundated with circuit-related fashion accessories in the past, but if you've already started thinking about what to get that lovely lad (or lady) in your life come February, look no further. SenseBridge, a research group with loads of passion, has just revealed the Heart Spark ($69, on sale now) -- a wearable pendant with an integrated wireless receiver, a smattering of LEDs and a wow factor that's downright heartwarming. The fortunate wearer must also strap a belt around their chest in order to monitor their heart rate, which is then transmitted wirelessly to the Heart Spark; upon receiving the information, the onboard lights will flash at the same rate as your heart, making it easy for the love of your life to see when your heart is aflutter. Video demonstration is just past the break, and yes, it's about as precious as you'd imagine.
Medtronic debuts tiny lead-less pacemaker at TEDMED 2010
There are two pacemakers in the picture above. There's the typical clunky, stone shaped device with wires on the right -- and on the left, a device dwarfed even by a one-cent coin. This is the Medtronic wireless pacemaker, just revealed at TEDMED 2010, which can be implanted directly into your heart via catheter and permanently latch itself into flesh with tiny claws. Then, doctors can wirelessly monitor and even control the device from a nearby smartphone. Medtronic's working to make it even smaller still, and we're hoping to get more information soon. Welcome to the future, folks. %Gallery-106218%
Infrared laser shown to quicken heart rate, gives hope for ultra-small pacemakers
Here's an interesting one. Just years after a researcher in Japan realized that lasers could stimulate nerves, a professor of biomedical engineering at Vanderbilt University along with cohorts from Case Western Reserve have found that the same is true with the heart. By using an Infrared laser on an early embryonic heart, tests were able to show that the muscle was "in lockstep with the laser pulse rate." The crew also found no signs of laser damage after a few hours of experimenting, though obviously more extensive research would be required before any medical agency allowed such a device to be beamed underneath a human chest. The hope here is that this discovery could one day lead to ultra-small, implantable pacemakers, or better still, to "pace an adult heart during surgery." There's nary a mention of when this stuff will actually be ready for FDA oversight, but there's a downright creepy video of it all in the source link. Consider yourself warned.
Medical devices could be powered by nanowire generators and the human heart
Researchers at Georgia Institute of Technology are getting to the heart of the matter, developing nanowire generators which could power medical devices inside a patient that are powered by the patient's own heart. The team -- led by Zhong Lin Wang --first demonstrated working nanowires back in 2005, and have since demo'd the wired generators being powered by a running hamster, tapping fingers, and piezoelectric solar cells. In the most recent and interesting turn of events Zhong and company have just demonstrated the nanowires functioning inside of a living animal (in this case, a rat). These zinc oxide nanogenerators could be ideally suited to as the power source for things like glucose level monitors and blood pressure in the somewhat near future. The ultimate goal, Zhong says, is to make what are essentially self-powered medical devices. Sounds a little creepy, if you ask us, but it's probably better than a hamster running in a wheel powering your pacemaker, right?
Nike+ heart rate monitor tipped for June 1 launch
It was hinted at back in September 2009, now it appears certain that Nike will deliver a Nike+ heart rate monitor iPod accessory to the US on June 1st. The following Nike forum post by a long-time contributor and a suspected Nike employee has set heart valves aflutter: "I have a U.S. launch date for the Nike+ compatible heart rate monitor. It will officially launch on June 1, 2010, although it may reach some retail outlets slightly sooner. It will reach Canadian markets in June and will launch internationally in summer 2010, exact date to be determined." We might buy one just to prove that we're still alive.
Newfangled nanoscale scanning technique could improve heart health
Oh, nanotechnology -- your wonders never cease. Boffins at Imperial College London have been able to use live nanoscale microscopy (a technique called scanning ion conductance microscopy) in order to see the surface of the cardiac muscle cell at more detailed levels than those possible using conventional live microscopy. Without getting too gross on you, the new process could lead to improved designs of beta-blockers, the drugs that can retard the development of heart failure. Researchers are hoping that the findings could also lead to "improvements in current therapeutic approaches to treating heart failure and abnormal heart rhythms," and while these exceptionally detailed images are helping the cardiac muscle right now, we're hoping that this stuff could also bleed over to other fields of medicine. Ventricles crossed!
Sonic & Sega All-Stars Racing screens make a pit stop in your heart
click to enlarge Sega has dropped some new screens from its upcoming Sonic & Sega All-Stars Racing kart game, and if you don't find them completely charming, there's something broken near your left ventricle. We don't yet know if the game is any good or not, but if you look at these lush, colorful 3D recreations of classic Sega environments and characters and don't feel the slightest stirring down in your jaded, Mature excuse for a gamer heart, you better get it checked. Note that these screens come from the Xbox 360 version, which explains why Banjo and the Avatars (coincidentally a great band name) appear within. Enjoy. %Gallery-83937%
Arterial tandem: coronary drill gets cleared for use, MEMS sensor distinguishes between kinds of plaque
We know discussing things involving "arteries" and "coronary plaque" generally don't do much for one's appetite, but being the holidays and all, we honestly can't think of a more fitting way to remind you not to pig out this evening. Up first is a MEMS-based sensor designed by downright enlightened researchers at the University of Southern California, which is used to "distinguish between stable and unstable atherosclerotic plaques in coronary arteries." The idea here is to more easily determine whether a patient needs immediate surgery or simple lifestyle changes in order to remedy artery issues, though the process is still awaiting clinical approval before it can be used en masse. In related news, Pathway Medical has just received European clearance to sell its Jetstream G2 NXT coronary drill overseas (or "peripheral atherectomy catheter," as it were), which does exactly what you'd expect it to: clear clogged blood vessels in the treatment of PAD. If you're not already grossed out, feel free to tap the links below for more information on head past the break for a couple of video demonstrations. Mmm, honey ham!
Computer scientist mods Xbox 360 to detect heart attacks, girls still mysteriously elusive
We've seen so many mods around here that sometimes it's truly hard to get excited over the minor stuff. Well, this doesn't fall into that category in any way. A computer scientist at the University in Warwick has developed a method to use Microsoft's Xbox 360 to detect heart defects and help prevent heart attacks. Based on a demo created by Simon Scarle a few years back when he worked at Rare studio, it's based on a modded chip that -- instead of producing graphics for the game -- now produces data tracking how the electrical signals in the heart moves about damaged cells, creating a model of it. The model can then be used to help doctors to identify defects and disturbances in the heart's beating. This significantly decreases the costs and complications of creating a model of the heart, which is currently done by supercomputers and is very expensive. Scarle's project and findings were just published in the August issue of the Journal of Computational Biology and Chemistry. Looks like we'll all have a response the next time someone tells us that gaming is good for nothing, right?
Xbox 360 being used to detect heart defects
We've suffered our fair share of broken hearts at the hands of the Red Ring of Death -- now, the Xbox 360 is being used to mend our ailing blood-pumpers. A computer scientist at the University of Warwick in England recently did some sweet console modification to allow his 360 to calculate heart rhythms using a complex algorithm. Microsoft's console is capable of performing these calculations five times faster (and 10 times cheaper) than a lab computer, and has the added benefit of letting its users play Madden in between bursts of scientific study. To sum up, the 360 is now being used to cure heart disease, and the PS3 is being used to cure cancer. Ball's in your court, Nintendo.
Samsung Mini S2 portable HDD graced with colors that perfectly match your tacky beach gear
Sammy's done it again. The company, known to have a penchant for pink products, has unveiled two new eye-catching colors for its Mini S2 portable HDD series. Joining the already available Snow White are Ocean Blue and Sweet Pink, pictured -- and yep, if you look closely enough, that's a sea of hearts lining the case on the right. All other options appear to be the same as when Samsung first unveiled the 2.5-inch drive, with capacity options ranging from 160GB all the way up to 500GB, and it's current status is "coming soon" in Korea, with options to import likely to follow shortly after. Catering / pandering to the female audience? You betcha, and if this pic's not proof enough, hit up the break for an image that's decidedly more in line with the device's initial inspiration / concept art. [Via Engadget Spanish]
NC State gurus keep hearts beating outside of the body
If NC State's athletic branches had even half the aptitude as its medical researchers, maybe then those blue boys down the road wouldn't have so much right to bang us up. Personal beefs aside, we're simultaneously stoked and amazed by a new machine crafted down in Raleigh, one that enables scientists to keep a heart pumping even after it has been removed from the body, but for research purposes only. Andrew Richards, a bright young mechanical engineering student, designed the so-called dynamic heart system, which "pumps fluid through a pig heart so that it functions in a very realistic way." Obviously, such a device has a multitude of benefits, including time / money savings compared to alternative approaches, the ability to record the inner workings of a pumping heart and scoring the creator some serious street cred in the industry. Mind-blowing video is just after the break.[Via Neatorama]
