A Ph.D. student at the University of Toronto is using the same transfer paper currently affixing temporary tattoos to kids -- in conjunction with a common screen-printing technique -- to develop a medical sensor that keeps tabs on a person's exertion by monitoring the skin's pH levels.

Similar devices, which are called ion-selective electrodes (ISEs), are already common among athletic trainers and medical researchers to help spot fatigue, dehydration, or even metabolic diseases. But they tend to be bulky and don't stick well to sweaty skin.

The new sensor stays put and doesn't look so, … Read more

Back in April of 2008 BJ (before Justin), motivational speaker James Arthur Ray guest-hosted The 404 Podcast and Jeff, Wilson, and Randall spoke to him about how to grow your own meat--no lie. Anyway, the show left a sour taste in The 404's collective mouth, and more than a year later it turns out that Mr. Ray is a big phony, not unlike Balloon Boy Sr.

Turns out that three people died in Arizona at a spiritual retreat "sweat lodge" organized by the self-appointed guru. It's a very sad story, and our hearts go out to the families of the victims. And James? Shame on you.

Oh, and surprise! The personal information you put up on the Internet is no longer private. According to this Wired Danger Room blog, a branch of the CIA has begun heavily investing in Visible Technologies, a software firm that monitors social media, including blog posts, Internet forums, online videos, radio reports, and so on. Luckily, Facebook is currently immune to such companies due to its closed architecture, but Twitter, Amazon, and YouTube are all fair game.

This report is definitely worth reading, but we're not surprised. Actually, we thought there was already a system set up to spy on our Web activities: it's called GOOGLE, and it's not doing such a great job at keeping our information private. The company is under suspicion of accidentally posting transcribed voice mails from its Google Voice service. Although this issue might actually concern me if my entire voice mail box weren't filled with concerned messages from my mother...

We're doing three Beck's Beer Audio Drafts this week to make up for the one we skipped last Friday due to Wilson's absence, and Wilson's pick for today is Works Progress Administration, a country outfit comprised of some of the most recognizable names in country music, including Glen Phillips from Toad the Wet Sprocket, Sean Watkins from Nickel Creek, and Benmont Tench from Tom Petty and the Heartbreakers.

The songs of the day are called "Good as Ever" and "Always Have My Love," and although Jeff and I aren't huge fans of the country music genre, we can definitely appreciate the musical talent of this supergroup, and Wilson chimes in to explain the difference between country-pop, country-rock, and a million other sub-genres. The band is currently on a West Coast Tour, so be sure to check out the WPA Web site for more details.

There are two major reasons to swap out the headphones that came packaged with your MP3 player. The first is sound quality, and the second is fit. The two are not mutually exclusive, but you may place emphasis on one over the other depending on your device usage. If you mainly use your MP3 player at the gym, getting a pair of headphones that both fit securely and offer some sweat resistance is key. The $40 Nike Aero Sport Headphones certainly fit the bill there, and although music doesn't sound great through this set, the sleek and sweatproof design … Read more

We previously reported on complaints of iPhones being damaged by sweaty workouts and the ensuing customer frustration when Apple responded then insisted those customers had to pay full price for replacements and extend their AT&T contracts.

Now Apple retail stores have adopted a new policy allowing them to charge less to replace water-damaged iPhones. We contacted the Apple store located at The Grove in Los Angeles, Calif. to verify the news. Representatives at the store confirmed that Apple now offers replacement iPhones for $199 (without a contract extension) if the phone has stopped working because of moisture damage.… Read more

Some iPhone owners are claiming that exercise, while good for you, may break your Apple device. Of course, as with most electronic devices, significant moisture can ruin Apple's iPhone, iPod Touch, and iPod. But now, some are saying that water damage may occur during activities as mundane as going for a jog.

This past Monday, KPRC Channel 2 in Houston ran a story during its Ask Amy consumer segment titled Ask Amy: iPhones Sweat Sensitive. (The video segment can be seen here.) In the segment, investigative reporter Amy Davis pursued consumer complaints about iPhones being damaged by sweat.… Read more
