Lung surfactant coats tiny air sacs in the lung. Without it, every breath is a struggle, like blowing up millions of little balloons. With surfactant, breathing is as easy as blowing soap bubbles.
Scientists will search the sky Thursday for an undiscovered planet in the outer solar system — they're pretty sure it's out there, and computer models tell them where to look.
How thin can a camera be? Rice University researchers created a "FlatCam" without lenses — one that can even be potentially made into wallpaper. Its roots trace to early pinhole cameras.
Overheated lithium-ion batteries have been a problem for airplanes, cars and even "hoverboards." A chemical engineer at Stanford University thinks she has a solution to the problem.
Named Sustainability Base, a NASA facility in California is a model for energy-efficient federal buildings. It's powered by a fuel cell like those used on spacecraft and recycles water for flushing.
NASA is building a 2-pound helicopter drone that would help guide the vehicle on the Red Planet's surface. That way, the rover wouldn't need to wander as much to find its way around.
Even the smartest robot does a miserable job picking up objects it hasn't been programmed to recognize. One way robots may get better at it is to learn by experience, a researcher says.
It was 15 feet long, with a snout shaped like a dolphin's. This newly identified meat-eater swam the seas near the Isle of Skye in the time of dinosaurs.
