During REM sleep, the respiratory pattern is irregular, with differences in the size of breaths and the spacing between them. Breathing during deep sleep follows an ordered pattern, "like a sine wave," says Bianchi. "And the breath-to-breath differences are very small." The lighter stages of non-REM sleep fall somewhere in between. "The motivation behind the shirt is to allow repeated measurements over time in the home," he adds. Users can log their habits, such as coffee or alcohol intake, exercise, or stress, and look for patterns in how those variables affect their quality of sleep.

"Throw in a nine-character, mixed-case random password, and while a CPU would take a mind-numbing 43 years to crack this, the GPU would be done in 48 days."

Facebook post bout how to enable a form of two factor authentication via SMS.  This system requires you to have your phone with you if you are accessing facebook from a new machine.  

Methods and systems for automated identification of celebrity face images are provided that generate a name list of prominent celebrities, obtain a set of images and corresponding feature vectors for each name, detect faces within the set of images, and remove non-face images. An analysis of the images is performed using an intra-model analysis, an inter-model analysis, and a spectral analysis to return highly accurate biometric models for each of the individuals present in the name list. Recognition is then performed based on precision and recall to identify the face images as belonging to a celebrity or indicate that the face is unknown.

While some organizations are still considering a basic social media facelift for their intranet, perhaps incorporating some blogs for corporate communication or a wiki area for some shared content authoring, it's almost certain that this is too little and too late for many companies. Over the last three years, the world has undergone a social media revolution that has changed the behaviors of most of the developed world that have gone on to be validated as beneficial for the workplace.

Wikipedia's tech team announces a test site for ensuring Wikipedia works seamlessly across mobile devices.  They are asking for input and testing support.

A series of 12 episodes are made available from Michael Sandel's innovative lecture series on morality and law.   Now anyone can essentially attend this highly sought-after class at Harvard. 

This guide is funded by the Robert Wood Johnson Foundation Pioneer Portfolio, which supports bold ideas at the cutting edge of health and health care, in partnership with Institute for the Future. Our goal is to gather and organize the world's collective self-tracking resources in one place, in a way that is useful and encourages collaboration between self-tracking experts and beginners who are just starting out.

Engineers have developed a device platform that combines electronic components for sensing, medical diagnostics, communications and human-machine interfaces, all on an ultrathin skin-like patch that mounts directly onto the skin with the ease, flexibility and comfort of a temporary tattoo. Led by researcher John A. Rogers, the Lee J. Flory-Founder professor of engineering at the University of Illinois, the researchers described their novel skin-mounted electronics in the Aug. 12 issue of the journal Science.

Studies show that younger generations really aren't that different from their older counterparts. Go figure.

YouTubers are some of the most innovative, entertaining and inspirational people in the world, and their creativity often needs more than the current upload limit of 15 minutes. Today, we're improving upon our previous launch by enabling long uploads for users with a clean track record who complete an account verification and continue to follow the copyright rules set forth in our Community Guidelines.

Use Google's ngram viewer to see how a word (or words) are used across time by searching for their prevalence in books.  

The apps are Color, Shopkick and IntoNow, all of which activate the microphones in users' iPhone or Android devices in order to gather contextual information that provides some benefit to the user.

Research out of Brigham Young University shows that political entries on Wikipedia are quite accurate and reliable locations to get information. 

encryption, as a preventive measure, assumes the primary threat is coming from the "outside" - typically (but not exclusively), in the form of a hacker trying to intercept communications or extract data from a lost or stolen device. While such threats are real and you absolutely must guard against them, we've reached a crucial point in the evolution of mobile technology, and just as importantly, user behavior where the primary mobile security threat is no longer the faceless and malicious hacker, but instead the legitimate, fully authenticated owner of the device itself.

So many cloud pundits are piling on to the misfortunes of Amazon Web Services this week as a response to the massive failures in the AWS Virginia region. If you think this week exposed weakness in the cloud, you don't get it: it was the cloud's shining moment, exposing the strength of cloud computing. In short, if your systems failed in the Amazon cloud this week, it wasn't Amazon's fault. You either deemed an outage of this nature an acceptable risk or you failed to design for Amazon's cloud computing model.

Before May 1st, not even the smartest of machine learning algorithms could have predicted Keith Urbahn's online relevancy score, or his potential to spark an incredibly viral information flow. While politicos "in the know" certainly knew him or of him, his previous interactions and size and nature of his social graph did little to reflect his potential to generate thousands of people's willingness to trust within a matter of minutes. While connections, authority, trust and persuasiveness play a key role in influencing others, they are only part of a complex set of dynamics that affect people's perception of a person, a piece of information or a product. Timing, initiating a network effect at the right time, and frankly, a dash of pure luck matter equally.

Google hopes that its slow rollout will encourage a steady momentum, and in the early stages Google+ will provide enough value to keep the early adopters engaged, and that it will motivate them to invite their contacts. No one expects an instant success. But even if this week's launch evokes snark or yawns, Google will keep at it. Google+ is not a product like Buzz or Wave where the company's leaders can chalk off a failure to laudable ambition and then move on. "We're in this for the long run," says Ben-Yair. "This isn't like an experiment. We're betting on this, so if obstacles arise, we'll adapt." "I don't really see what Google's alternative is," says Smarr. "People are going to be a fundamental layer of the internet. There's no going back."
