If you're like me, a jog without music just drags. Visions of the proverbial gerbil on the exercise wheel penetrate the brain, and the miles go by achingly slowly. Add the right song, at the right volume, and suddenly the run becomes something akin to enjoyable.

Recognizing the value of a good workout station, Pandora today announced a new workout genre with 12 stations. And the winners are:… Read more

We've written about mirrors that tell us more than whether we have a piece of spinach stuck between our teeth. A year ago, a Harvard-MIT student showed off a mirror that's able to read certain vital signs.

Now The New York Times Research & Development Lab is taking things a step further--bringing body tracking, shopping, news, and of course advertising to one's most intimate of places: the bathroom.

The group's "magic mirror" uses LCD and Kinect technology (it's really more of a computer with a reflective surface) that lets users browse the Web while brushing their teeth.

How is this better than using a smartphone in the bathroom? For one, it's hands-free. In fact, in the group's demo, one of the designers simply places a box of meds on the mirror's small ledge; it uses RFID tagging to recognize the type of meds and pull up information about dosages and where to buy more.… Read more

Let's all be thankful that the pictured woman enjoying her Shoulderflex isn't wearing a necklace or much in the way of clothing, and also that her hair is tied neatly atop her head. It turns out that necklaces, clothing, and hair have the potential to turn that peaceful look on her face into something else entirely.

No, seriously. One person was strangled to death after her necklace became caught in the personal massager's rotating component, while another was almost killed when a piece of clothing was caught. Still more have been injured when their hair became entangled in the device.

In light of the death and injuries, the Food and Drug Administration issued a warning last week that the device posed serious health risks, and yesterday the manufacturer, King International, voluntarily recalled nearly all of its 12,000 Shoulderflex massagers in the U.S. sold between 2003 and 2011.

To be fair, the promotional demonstration of the massager advises users to keep hair and jewelry away from the rotating bar--an obvious caution reminiscent of the floor being slippery when wet.

The video did not, however, warn that failure to do so could result in death by strangulation. (The video appears to have been deleted from a variety of sources as the Beaverton, Ore.-based firm tries to extricate itself from the unraveling imbroglio. Calls to the company for comment, meanwhile, went straight to voice mail.)

If you've got a Shoulderflex on hand, the FDA implores you to throw it away.… Read more

Radiation therapy requires oxygen to be effective, which makes cancers that tend to be hypoxic (meaning they are deprived of oxygen)--such as pancreatic and cervical cancers--harder to treat. (Tumors can become hypoxic for a few reasons, e.g. they grow so quickly they actually outgrow blood supply, or cells proliferate so many times that the density taxes the available oxygen.)

So researchers at Purdue have been building and testing tiny devices that can be implanted in tumors and then generate oxygen, thereby making the area far more susceptible to radiation and chemotherapy.… Read more

A good nose can be a curse. Dogs, for instance, have been shown to be able to sniff out lung cancer in humans, which means the poor creatures have to smell our breath, with a lot of smokers in the mix, one sample at a time.

Good news out of Germany, then, for man's best friend. A team of scientists at the University Hospital Jena is testing an electronic nose system that's able to distinguish between people without heart failure and people with it, and even between two types of heart failure (compensated and decompensated) with almost 90 percent accuracy--higher than what canines were able to achieve in the lung cancer study.

The system includes three thick-film metal oxide-based gas sensors with heater elements. Each is tailored to sense different odorant molecular types. As oxygen reacts to the heated sensor surface, the molecules interact with the sensors and change the free charge carrier concentrations, and thus conductivity, in the metal oxide layer.… Read more

I need to reprioritize the items in my Hurricane Irene Go Bag. How do I know this? Because this a.m. I found myself struggling to decide which toy my cat would prefer should we be forced to evacuate our home early tomorrow morning.

Before you go planning a disaster movie marathon this weekend, be sure to check out the NYC Hurricane Evacuation Zone map or enter your address in the Zone Finder to see if you live in an evacuation area.

And if you do live in one of the affected areas, you can download apps for both iOS and Android devices that show Doppler radar info, detailed maps, and ongoing weather warnings and satellite images for up-to-date news on the storm. But what should you pack in your emergency "Go Bag"? … Read more

A professor of civil and environmental engineering at Michigan State University has unveiled a device that, in conjunction with an iPod Touch or Android-based tablet, analyzes microRNAs to detect cancer quickly and affordably.

Syed Hashsham says his Gene-Z device, which he demonstrated this week at the National Institutes of Health's first Cancer Detection and Diagnostics Conference, in Bethesda, Md., could dramatically improve early cancer detection in developing nations that have few, if any, cancer screenings services.

"Until now, little effort has been concentrated on moving cancer detection to global health settings in resource-poor countries," Reza Nassiri, the … Read more

As anyone who has broken a bone knows, keeping up with physical therapy post-injury can be painful and annoying, and without a clear way to gauge progress, the regimen is as tempting to avoid as a bland diet.

Recent Copenhagen Institute of Interaction Design graduate Pedro Nakazato Andrade hopes to keep people motivated--and thus improve recovery time--via a prototype cast that employs electromyographic sensors, which measure the electrical activity produced by a muscle when it moves.

Called "Bones," his cast prototype can keep a running tally of how much the injured area is being exercised.

The idea behind the design is rooted in the idea behind weight loss programs such as Weight Watchers: people who can track their progress using real, hard data are more likely to stay motivated and keep doing what they have been told to do.… Read more

Yesterday started like so many others, with me standing in the back of a noisy, sweltering bus that smelled of urine. But unlike previous mornings, this time I was able to use my phone to quantify my stress level as it mounted with each jarring pothole.

Armed with a new app called Stress Check on my iPhone, I could verify that the stress I was feeling was real--when I woke up my level was 1 percent, but on the bus it topped 100. And while a number of apps require an external attachment to take health measurements, Stress Check required just me and my phone.

Released a couple of weeks ago, Stress Check is one of several apps from Palo Alto, Calif. start-up Azumio, which recently received $2.5 million in series A funding. The company's first health-oriented app, Instant Heart Rate (also available for Android), has generated 8 million downloads since its release in January. The company has more apps in the pipeline.

If it's easy, and fun, to collect personal health data, more people will likely be inclined to do so--and take action, reasons Azumio co-founder Bojan Bostjancic, who stopped by CNET headquarters last week to demo the company's health apps. … Read more
