Every month, between 50 and 70 million passengers travel through U.S. airports, toting more than 30 million pieces of luggage destined for aircraft cargo holds
In the United States, about 80 million x-ray computed tomography (CT) scans are made every year – 7 million of them on children – according to the American
In living organisms, biomolecules such as proteins are constantly in complex motion, bending and flexing in different ways at different points. Each molecule
In the pursuit of precision measurements, nothing is simple, even when the apparatus employed appears to be utterly uncomplicated. An instructive case in point
Why there is stuff in the universe—more properly, why there is an imbalance between matter and antimatter—is one of the long-standing mysteries of cosmology. A
The idea of probing the body's interior with radiation stretches back to experiments with X rays in the 1800s, but more than a century later, images taken with
