If you've ever played around with one of those carbon or water footprint calculators, you probably know that meat production demands a lot from the environment — a lot of oil, water and land. (Check out the infographic we did on what goes into a hamburger last year for Meat Week.)

But have you thought about your meat's phosphorus footprint? Probably not.

It sounds like something out of a spy movie: A new app called Silent Circle allows users to "burn" sensitive messages sent on their phones.

Jon Callas, one of the people who developed the app, says the idea is pretty simple.

"It's a timer. So you can say, one hour; seven minutes. Whatever," Callas tells Jacki Lyden, host of weekends on All Things Considered.

It's called a "burn notice." When the time's up, the text is erased from both the sender and receiver's phones.

That hesitation right before a kiss

I don't remember ever learning this

I've never had a valentine before

I'm not a little baby anymore

It's poetry — rhyming couplets written in perfect iambic pentameter, those ten-syllable lines of alternating emphasis made famous by authors of sonnets and blank verse. But unlike your average metered rhyme, these lines were written by Twitter ... with some help from a program called Pentametron.

You really don't want to mess with your Achilles tendons. Trust us, injury to these tendons can take months to heal, and even then recovery is often not complete.

A big reason the Achilles is such a foot-dragger at getting better is that the tendon tissue we have as adults is basically the same as we had when we were teenagers.

That finding was published earlier this week in The FASEB Journal.

A new study released by the UT Health Science Center at San Antonio found primary care clinicians may be missing three-fourths of the alcohol problems in their patients.
