Green Science is the application of eco-friendly thinking to scientific disciplines. Learn about global warming, pollution and other impacts on nature and the planet, plus what we can do to combat them.
In an effort to detect areas with poor air quality, China is training people to sniff out harmful levels of pollution. But what effect does this have on the human body? Learn about how the brain identifies and distinguishes among scents as well as new odor-detecting technology.
Clean coal -- isn't that an oxymoron? Not anymore. See how energy companies are using coal in cleaner ways to generate massive amounts of electricity. Alternative fuels may be making headway, but coal isn't used up yet. Find out why.
When the wind blows, particles in the gust of air are moving quickly. And that motion carries kinetic energy, which can be captured and harnessed to create electricity. The principle behind a wind-electric turbine isn't too different from an ordinary dam -- only it's capturing wind instead of water.
What happens to all of that trash the dump truck picks up every week? It doesn't just disappear into a parallel universe: Each day, we all contribute to the local landfill, and the waste disposal system is pretty involved.
