Methane Gyrations Last 2,000 Years Show Human Influence On Atmosphere
Humans have been tinkering with greenhouse gas levels in Earth's atmosphere for at least 2,000 years and probably longer, according to a surprising new study of methane trapped in Antarctic ice cores conducted by an international research team that involves the University of Colorado at Boulder.

Hydrogen-generating Technology Closer Than Ever
Researchers have further developed a technology that could represent a pollution-free energy source for a range of potential applications, from golf carts to submarines and cars to emergency portable generators. The technology produces hydrogen by adding water to an alloy of aluminum and gallium. When water is added to the alloy, the aluminum splits water by attracting oxygen, liberating hydrogen in the process. The researchers are developing a method to create particles of the alloy that could be placed in a tank to react with water and produce hydrogen on demand.
