New Technology Could Let Disabled Communicate by Sniffing
If you're paying attention, there can be an awful lot of information encoded in a series of nose sniffs. In and out, long and short, strong and shallow. One sniff, two sniffs, three sniffs.

An Unbelievable Accent
If I told you that "ants don't sleep," would you believe me? What if I were speaking with a foreign accent?Researchers at the University of Chicago have found that we judge non-native speakers to be less believable, though not because of any bias against foreigners.

Here in the United States, the disease is rare—only 12,904 cases were reported in 2008—and generally treatable with antibiotics. Outside of North America, Au...

Wearing a Water Filter
Water is something that's easy to take for granted, especially in a developed country where the taps run clean and clear.

Odd Malaria Risk Factor: Drinking Beer
Here in the United States, we rarely have to worry that a mosquito bite will cause malaria. Like Canada, Australia, much of Europe and a few other places, we've been designated "malaria-free" by World Health Organization. Other places aren't so lucky. Nearly one million people died from the disease...

Vaccines Don't Cause Autism
It's rare in science and science writing to make definitive statements, particularly about causation. We like to add what I call "wishy washy" words like "may" and "probably" and "perhaps."
