More than $7 billion in drugs, vaccines and supplies are stashed in warehouses to be tapped in case of a pandemic or an attack with chemical, biological or nuclear weapons. NPR got a peek at one.

The fields bend the hairs, and that generates a nerve signal, scientists say.

It's not unusual for males to try to impress females with big body parts. Consider antlers on deer, or elaborate tails on peacocks. Some male fruit flies take a different approach: giant sperm.

The women being monitored now include those who had positive lab tests but no symptoms, according to the CDC. Also affected are 122 women in U.S. territories, almost all in Puerto Rico.

The U.S. is the proud owner of the world's largest deadweight machine, used to calibrate high-tech measurement devices. Repairing it recently was risky, using 50-year-old tools. No toes were smashed.

Scientists have found the first eukaryotic organism that functions fine without mitochondria, the "powerhouses" that make energy for the cells of yeast, humans and other animals.
