These tiny, lightweight gadgets could mean huge savings for farmers "Farmers have a very good eye. They can look at their crop if they've been farming for a long time and say, 'My crop needs water, I can tell,'" says Richard Stoner, founder of the biotech and agriculture company, AgriHouse. So who might know more about what a plant needs than a farmer or a greenhouse owner? How about the plant itself? What if plants could tell us when they are thirsty? With funding from the National...

Community college program trains future wind power technicians Soon, 44-year-old Brad Clark will begin his second career, 300 feet off the ground. "About a year ago, I got laid off from my position in high tech," explains Clark. "I'm an engineer by education and training, and once I got laid off, I had to think, what do I want to do? What's going to be a business that is going to be around? So I was part of a government retraining program." For more Science Nation, go to...

Unmanned Helicopters Could Help Air Traffic Controllers Small aircraft could have big impact on safety The chilling video of a small plane and helicopter colliding over the Hudson River in early August showed that technology can't always protect the crowded skies. Nine people died in that crash in New York City. Some answers to better collision avoidance systems may come from unusual tools: small, autonomous helicopters that are getting smarter all the time. "We're interested in...

Sunspots have fascinated mankind right from their first detection. Their mere existence challenged science and philosophy when it was recognized that the sun, once believed to be pure and unchanging, was indeed not. Now, state-of-the art telescopes, combined with the muscle of a supercomputer called "Bluefire," are allowing scientists to come to a physics understanding of sunspots and to accurately model their structure and dynamics.
