Do you think cheerleaders are airheads? Think again. Many of the women you see dancing on the sidelines during games also have degrees in science, technology, engineering and mathematics.
When researchers need to take measurements under the ocean, on glaciers or even on other planets, they turn to Alberto Behar. He helps them overcome the challenges of using sensors in extreme conditions.
Get up close and personal with brain tissue, kidney cells, cyanobacteria and more. This slideshow lets you glimpse the realm of the tiny through confocal microscope images.
To receive a U.S. patent, an invention must be considered new, useful, and non-obvious. You cannot patent inventions that are already widely used or described, that have no useful purpose, or that would be obvious to anyone with ordinary skill in that art.
A soldier walks through a building in a war zone. Suddenly, an alarm begins going off in his pocket. He pulls out a sensor about the size of a deck of cards. The sensor has detected the disease-causing microbe anthrax. Okay, soldiers don't really have sensors this small and reliable yet. But scientists are working to create them.
Air is all around you. It presses against your body all the time. That’s why we call it air pressure. Anyone can measure air pressure using a tool called a barometer. Barometers work because air has weight.

Knud-niks, Neewalkers, O-dats, Keepers and holographic rooms. What do they all mean? A new Wiki created by high school students will explain it all.
