Scientists at the National Institutes of Health made an unpleasant discovery last week as they cleaned out an old laboratory: The lab contained vials of the smallpox virus, previously unknown to authorities. The vials have since been transferred to a secure lab at the federal Centers for Disease Control and Prevention in Atlanta.
According to new research, plants can actually hear the sounds of insects chewing. A University of Missouri study is the first work to report that plants can recognize the sound of a predator through the vibrations of their leaves. To learn more, Robert Siegel speaks with Heidi Appel, senior research scientist in the Bond Life Sciences Center at the University of Missouri.
Somewhere in Iowa, volunteers are earning $900 apiece by providing blood samples after eating bits of a banana kissed with a curious tinge of orange.
It's the first human trial of a banana that's been genetically engineered to contain higher levels of beta carotene, the nutrient that our body converts into vitamin A. Researchers want to confirm that eating the fruit does, in fact, lead to higher vitamin A levels in the volunteers' blood.
The volunteers in Iowa may not realize it, but they're playing a small part in a story that spans the globe.
