Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean.

The U.S. Environmental Protection Agency has released a report that discusses the potential impacts of climate change on human health, human welfare, and communities in the U.S.

A transition to hydrogen vehicles could greatly reduce U.S. oil dependence and carbon dioxide emissions, says a new congressionally mandated report from the National Research Council, but making hydrogen vehicles competitive in the automotive market will not be easy.

Revisiting a once-abandoned technique, engineers at the Massachusetts Institute of Technology (MIT) have successfully created a sophisticated, yet affordable, method to turn ordinary glass into a high-tech solar concentrator.

Companies that develop green production processes can not only offset the costs of regulations, but can reap financial benefits.

A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers.

The forests of the future may need to be managed as much for a sustainable supply of clean water as any other goal, researchers say in a new federal report – but even so, forest resources will offer no "quick fix" to the insatiable, often conflicting demands for this precious resource.

It's summertime and people are flocking to the coasts around the country. But when summer storms arrive, it's not only beach-goers who are affected; the rains can also have an impact on living creatures far below the ocean surface.

I propose to you the following conjecture: Is it possible to directly convert solar energy in a mechanical form?

Closing coal-fired power plants can have a direct, positive impact on children's cognitive development and health.
