It may look a little strange, but Pranayama does a great job guiding you through stress-reducing breathing exercises.

The holidays can be a stressful time. So can the weeks that follow. And Mondays, Mondays are always tough. The Swine Flu won't go away. Who's ready for financiapocalypse 2010? Glenn Beck says the country's ruined. Locusts! Ahhhhhhhh!!!

Whew, I need to relax. Easier said than done, right? Enter Pranayama and Stress Free with Deepak Chopra, two new iPhone apps designed to help you trade stressed-out for chilled-out.

Pranayama performs one basic function: guided breathing. According to the developer, research shows that 15 daily minutes of slow, deep breathing can improve overall health and even treat ailments like depression and insomnia.

To get started, you choose a "skill" level, breathing pattern (inhale/exhale or inhale/retain/exhale), and timing option (how long each step should last). Then, just tap Play. You'll hear a musical tone that corresponds with inhaling, then a different one for exhaling.

This audio-guided method lets you focus on your breathing without having to count or look at the screen (which, for the sake of learning, features an animated torso showing how to use your abdomen properly).

It's a simple, straightforward app, with lots of good built-in instructions and information. The $4.99 price tag may seem a hair steep, but it's a bargain if you get results.

Stress Free with Deepak Chopra is like an interactive self-help book.

Stress Free with Deepak Chopra is more of a soup-to-nuts self-help program, complete with activities, music therapy, nutrition advice, and videos of the mental-health guru himself.

It's designed to play out over the course of six weeks (though you can go at your own pace), with each week spent on the various stages of six "keys" to a stress-free life.

Along the way you'll get a daily e-mail showing your progress in the program and a recommended exercise. So this isn't just an app you turn to when you're feeling stressed; rather, it's a systematic self-help book made interactive.

And it offers some impressive features that no book could match. For example, in one activity you're encouraged to commune with nature--and the tap of a button displays nearby parks in Google Maps.

(Neat idea, bad implementation: the search missed most of the actual parks in my area, but instead found neighborhoods and developments with the word "park" in their name.)

Overall, there's a lot to like about this thorough, inventive app, and I can see where it will appeal to some users. However, I found it a little too touchy-feely, and something about Chopra himself rubs me the wrong way.

Will you like Stress Free? It'll cost you $8.99 to find out.

A new type of artificial larynx could mean better-sounding speech for those who've had their larynx removed due to laryngeal cancer or other ailments.

Researchers hope the SmartPalate can work for those without a larynx. The space-time graph pictured below the device corresponds to the tongue-palate contact pattern for the word "been."

Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have come up with a system that tracks mouth movements to determine what word is being formed and then uses a speech synthesizer to audibly produce the correct word.

"All of the currently available devices produce such bad sound--it either sounds robotic or has a gruff speaking voice," Megan Russell, a Ph.D. candidate at the university, told Technology Review. "We felt the tech was there for an artificial synthesized voice solution."

Russell and her colleagues created the software for the system, which is being shown off this week at the International Conference on Biomedical and Pharmaceutical Engineering in Singapore. For their research, the team is training a retainer-like mouthpiece already utilized in speech therapy to recognize words mouthed by people without a larynx.

The mouthpiece, called a SmartPalate, is made by Utah-based company Complete Speech. It uses 118 embedded sensors to track tongue-to-palate and lip closure contacts.

A microprocessor input/output device worn around the user's neck or placed on the desktop connects the SmartPalate to a personal computer, and software produces real-time, onscreen visual feedback that shows those with speech impediments how to reposition their tongues.

The system being developed in South Africa, according to Technology Review, would translate mouth movements into words to be reproduced on a small sound synthesizer that could be kept in a pocket.

Russell has trained her software to recognize 50 common English words by saying each one multiple times with the SmartPalate in her mouth. The information picked up by the sensors can be represented on a graph and put into a database, and each time the wearer configures his or her mouth to form a word, the contact patterns are compared against the data to identify the right word.

Russell says the system identifies correct words 94.14 percent of the time, although this doesn't include words that the system classifies as "unknown" and chooses to skip.

Please forgive me if I take the easy humor route and inject a few "Twilight: New Moon" jokes into my posts over the next few days. I haven't been sleeping well and when that happens I get groggy and tend to go for the easy laugh. The problem is that some nights I just don't get enough sleep (no, not a vampire). I go to bed at different times and always try to wake up at 8.

That being said, I'd like to try the WakeMate sometime to see how it can help me be more rested so I can make better jokes for all of you. It's a cell phone accessory that monitors and analyzes your sleep and then uses the data to wake you up at the optimal point in your sleep cycle.

Sleep analytics like this have been around for a while, but WakeMate appears to be the first system that uses off-the-shelf components (Bluetooth, iPhones, etc.) to bring the method to the masses.

Sleepers wear a wristband that tracks movements during sleep. The motion data is then analyzed to determine sleep patterns and circadian rhythms and sent to a device, like an iPhone, via Bluetooth. At just the right moment in the sleep cycle, the alarm goes off, hopefully waking snoozers to a great morning. Also included are personalized instructions on how to improve your slumber.

The WakeMate is the first product from Perfect Third, a company funded by venture firm Y Combinator, which focuses on early-stage start-ups. Other noted Y Combinator-funded companies include Loopt, Justin.tv, and Reddit. WakeMate is available for preorder for $49.99 from Perfect Third's site and we're guessing we'll hear a lot more about it in the coming months--if we can stay awake, that is.

The WakeMate delivers data on your sleep patterns, as well as suggestions for getting more rested.

Add another robot to the list of helping bots for seniors. A robot named Charlie rolled into a New Zealand retirement village on Monday to take residents' vital signs, deliver their medication reminders, and call for assistance if they fall.

Charlie's trial stint at Selwyn Retirement Village in Auckland's Point Chevalier is, in part, a response to a University of Auckland study exploring seniors' attitudes toward robots.

The study--part of a three-year "HealthBots" collaboration by the University of Auckland and Korea's Electronics and Telecommunications Research Institute--collated the opinions of Selwyn Retirement Village residents, their families, and staff on what tasks health care robots could perform and what the mechanical helpers should look like.

Results showed respondents felt most comfortable with robots taking vital signs such as blood pressure, calling for help, lifting heavy objects, cleaning, and making phone calls to a doctor or nurse. They did not identify personal care, medical advice, and assessing emotions as tasks they'd like to see taken over by robots.

As far as physical appearance, residents and staff indicated they preferred a "middle-age robot" with a clear voice, though they didn't have a preference for male or female features. The robot shouldn't be too human-like, they suggested, with some residents explicitly saying they'd rather be tended to by a robot without a face. The preferred design was silver and around 4 feet tall, so the robot was not too imposing, with wheels and a screen.

Enter Charlie, which pretty much fits that description. ... Read more

I have nothing against smoking, save for the difficult odor that emanates from every part, breath, and piece of clothing belonging to a smoker. I could no more live with a smoker than I could live with a third ear perched off the end of my nose.

However, I am embalmed in a curious sympathy after reading a report from The Consumerist concerning two Mac users whose AppleCare warranties appear to have been voided due to the presence of cigarette smoke in their homes.

One, named Derek, recounts the tale of his overheating black MacBook. He took it into the Apple store in Jordan Creek, West Des Moines.

He told The Consumerist: "Today, April, 28, 2008, the Apple store called and informed me that due to the computer having been used in a house where there was smoking, that has voided the warranty and they refuse to work on the machine, due to 'health risks of secondhand smoke.'"

He continued: "Nowhere in your AppleCare terms of service can I find anything mentioning being used in a smoking environment as voiding the warranty."

Will a Marlboro Lights habit makes this cute thing inoperable?

Derek's resulting appeal to the office of Steve Jobs bore him no joy, so he resorted to blowing some compressed air at the machine, leading it to restart its wondrous functions.

Then along came Ruth, who took her son's iMac to an authorized repair center. After five days, they apparently told her they couldn't work on it because it was contaminated with cigarette smoke and was therefore a bio-hazard.

Cardiac patients undergoing procedures at the National Heart Centre Singapore (NHCS) starting Thursday may find themselves either immersed in a Disney World setting or the African Savannah, with accompanying audio playing in the background. It's part of a testbed project by the center involving Philips' Ambient Experience to soothe patients through the intimidating clinical process of preparation, examination, treatment, and post-procedure.

The Ambient Experience takes patients on a multimedia ride, letting them personalize the lighting, projected images, and sounds in the examination or lab room. The 10 themes can be selected via a menu on a wireless touch-screen tablet, with more themes on the way. Once picked, the patient's choice is projected on the walls and ceilings and through TV screens, wrapping the user in a multi-sensory setting of his or her own choosing.

The wireless touch screen lets the patient instantaneously personalize the room's "theme."

So far, the Ambient Experience appears to have had a positive impact on the three patients who earlier sampled it. According to 75-year-old Neo Bee, who was at the cardiac catheterization laboratory to have angioplasty to open her blocked arteries, "I saw birds and kangaroos on the ceiling and there was soothing music, too. I felt calm and relaxed."

Just in time for the crazed holiday shopping season, San Francisco-based GoodGuide releases the first iPhone app that lets you scan bar codes for what the guide calls "impartial" health, environmental, and social responsibility ratings of not only the products you are scanning but their companies, too.

GoodGuide's free app lets you scan an item's bar code and instantly retrieve info on that product's health, environmental, and social responsibility ratings.

As our Webware staff wrote in August, "GoodGuide is the reason we have awards for tech services and products: it's a small and relatively unknown service that demonstrates real leadership on the Web." And as we report in Health Tech just this week, GoodGuide is an invaluable resource when shopping for toys, as it provides the levels of lead, mercury, chlorine, etc., that might be in the toys.

But GoodGuide's newest app is quite possibly the group's pinnacle achievement thus far. Now, instead of having to be organized enough to do your research online before hitting the stores, or using the app's 2008 iteration, which involves entering a product into a GoodGuide database on your phone, now anyone with an iPhone can literally scan bar codes while shopping.

Seriously, this could become a tick. I kind of want to spend all day scanning bar codes with the same fervor I used to pop package bubbles as a kid. As GoodGuide spokesperson Suzanne Skyvara (mother of two boys, ages 8 and 5) tells me in a delightful English accent that somehow makes everything sound healthy and socially responsible: "It's making it easier to be good. We all want to do this, but god, who's got the time to research it all?"

I envision scoffing with delight at the higher-priced products that don't actually measure up to their less expensive counterparts, a discovery likely as satisfying as catching a poker player mid-bluff. Or, conversely, I can see justifying a slightly more expensive product that is far healthier for my body and environment.

Of course, the value of such a system hinges on how good the information is. GoodGuide licensed Occipital's RedLaser bar code-scanning technology for this app and culled ratings for more than 62,000 food, personal care, household chemical and toy products and companies, and plans to add thousands more every month. Learn more about GoodGuide's rating system here.

Best of all, of course, is that GoodGuide's app is free--a fact that also sounds delightful in an English accent. All you need is the funds to own an iPhone, but that's a different story.

It even looks good.

You take a scale. You give it Wi-Fi. And then you let it log in to your Twitter account to tell the world how much you weigh each morning. That's what this is: the Wi-Fi Body Scale.

At first it sounds silly, but the more I think about it the more I like the idea. If I'm trying to lose weight, this is a good way to force me to watch what I eat lest I embarrass myself in front of my Twitter followers. If it shows me blowing up like a whale instead of dropping pounds then I don't just know I'm doing something wrong, my peers do, too. Shame can be a powerful tool.

The $159 scale already records the user's body weight, lean and fat mass, and calculated body mass index (BMI) to a secure Web site accessible by the user. The Twitter integration, though, is a new feature. The Twitter feature is being called "peer motivation" by Withings, the scale's maker, and they're right. I'd call it "weight loss by fear as motivation," but I'm just some blogger.

A wireless digital 'plaster' that monitors vital signs is being tested on patients and volunteers at Imperial College London.

When you go to the doctor and you get your heart rate or blood pressure taken, the resulting data is narrow, since the measurements are taken of you doing just one thing: sitting still. True monitoring throughout someone's typical daily activities has until now been something of a pipe dream.

All that could be about to change.

A range of vital signs, including body temperature, heart rate, and respiration, is currently being monitored--continuously and remotely--by a small strip of digital plaster affixed to a patient's chest, neck, and/or arm.
