The more you sit, the less physically active you are, which can lead to all sorts of health problems, including an early death.
But too much sitting increasingly looks like a health risk all its own. Researchers at Northwestern University say that for people 60 and older, each additional hour a day spent sitting increases the risk of becoming physically disabled by about 50 percent — no matter how much exercise they get.
Have you ever watched a little kid playing in a sink full of water? It could be the kitchen sink, the bathroom sink or even the tub — it's all the same to kids. The faucet goes on.

This past weekend marked the 450th anniversary of Galileo's birth. In articles celebrating his contributions to science, Clara Moskowitz at Scientific American wonders what he'd make of contemporary science, while Dan Vergano at National Geographic credits him with nothing short of the invention of "our own modern world."

Electronic cigarettes are often billed as a safe way for smokers to try to kick their habit. But it's not just smokers who are getting their fix this way.

And between 2011 and 2012, e-cigarettes doubled in popularity among middle and high school students.
As flu-watchers like to say, you can always count on influenza virus to surprise.
The latest revelation is that scientists have apparently been wrong about where new flu viruses come from. The dogma is that they always incubate in wild migratory birds, then get into domestic poultry, and then jump into mammals — especially pigs and humans.
Secretary of State John Kerry is continuing a push to move climate change to the top of the global agenda, telling an audience in the archipelago nation of Indonesia that rising global temperatures and sea levels could threaten their "entire way of life."
