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.

When it comes to treating a lazy eye, there's evidence that turning the lights off may help — if you're a kitten.

When the X-ray was invented, people clamored to get one. Not for any medical reason, but just to see what was typically hidden inside their bodies.
Something like that seems to be happening with DNA sequencing technology. First it was companies offering to sequence people's genomes. Now it's learning all about your microbiome, the collection of microorganisms living on and in your body.
U.S. companies that have their networks routinely penetrated and their trade secrets stolen cannot be surprised by a new National Intelligence Estimate on the cyber-espionage threat. The classified NIE, the first-ever focusing on cybersecurity, concludes that the U.S. is the target of a major espionage campaign, with China the leading culprit.
Every few million years or so, the Earth burps up a gargantuan volcano.
These aren't like volcanoes in our lifetimes; these "super volcanoes" can erupt continuously for thousands of years. While they might be rare, you'd best look out when one hits.
The ash and volcanic gases from these volcanoes can wipe out most living things over large parts of the planet. Michael Thorne, a seismologist at the University of Utah, has some clues about what causes these big eruptions.
