Virtually no one starts smoking after age 26

There's a reason the government has had to severely restrict cigarette advertising (and smoking in general) to minors: they're the only ones still gullible enough to think smoking is a good idea.

A Common Bacteria Can Be Injected Directly Into Tumors to Fight Cancer

In its natural form, Clostridium novyi is at best benign (it lives in the soil) and at worst harmful (it can cause infections). But a slightly modified version of the bacterium could be a completely new treatment for cancer.

Why E-Cigarettes Might Not Be as Safe as You Think

It's little wonder why e-cigarettes' popularity has exploded into a $2 billion industry over the last few years; the promise of safe, harmless nicotine delivery without all the carcinogenic byproducts of looseleaf combustion is a hard offer to pass up. But are these devices and the nicotinated fluids they atomize… » 8/13/14 12:30pm 8/13/14 12:30pm

The Truth About Cholesterol

For years conventional medicine has told us that high cholesterol levels contribute to heart disease, and as a result, doctors have instructed patients to keep cholesterol levels low – at nearly any cost.

See Inside a Living Mouse Brain Thanks to Lasers and Carbon Nanotubes

The living brain has always been a tricky thing to study. How do you figure out what's going on without poking, prodding, and jostling the brain so much that it's not working right? A relatively non-invasive new technique developed by neuroscientists at Stanford and Massachusetts General Hospital uses a laser and… » 8/07/14 4:21pm 8/07/14 4:21pm

What the Heck Is Toothpaste Anyway?

It's been part of humanity's hygiene regimen for more than 4,000 years, but have you ever stopped to think what's actually in the stuff you're smearing across your teeth? The ingredients of modern toothpaste may read like a mad scientist's shopping list, but they're far better than what our ancestors had to endure for… » 8/05/14 2:20pm 8/05/14 2:20pm

A Better First Aid Kit That Makes Suggestions and Knows What's Missing

Even a well-stocked first-aid kit is all but useless if you crack it open but have no idea what's actually needed for a particular emergency. So these aptly-named Clever Medkits feature a series of buttons and LED lighting that only illuminates the medical supplies needed for a specific injury, and it will even remind… » 7/30/14 1:29pm 7/30/14 1:29pm

How the "10 Percent of Our Brains" Myth Started (And Why It's Wrong)

Morgan Freeman can make anything sound legit no matter scientifically implausible. In Lucy for example, which premiered last Friday, his character cites the "fact" that humans only use about 10 percent of our brain's resources. This is very, very wrong! But why does it keep getting tossed around? And how much of our… » 7/29/14 12:00pm 7/29/14 12:00pm
