The project hasn’t reached full-scale yet, but the renewable energy research project that started out in a Nevada lab has reached demonstration stage at a water reclamation facility. The process dries sludge that is normally trucked away for disposal, converting it to solid fuel that can be gasified to produce electricity.

Scientists already know that some types of bacteria can alter uranium (VI)—a radioactive, toxic, and water-soluble relic of the Cold War era—into uranium (IV)—insoluble, stationary, and less harmful. Argonne Lab studies are beginning to unlock this pathway, but because bacteria interact with so many other elements, harnessing their abilities will prove difficult.

With inspiration from a semi-tropical frog that makes its own long-lived foam, engineers from the University of Cincinnati have blended plant, bacterial, frog and fungal enzymes to create foam that captures energy, converts to sugar, and removes excess carbon dioxide from the air.

If harnessing the unlimited solar power of the sun were easy, we wouldn't still have the greenhouse gas problem that results from the use of fossil fuel. And while solar energy systems work moderately well in hot desert climates, they are still inefficient and contribute only a small percentage of the general energy demand. A new solution may be coming from an unexpected source—a source that may be on your dinner plate tonight.

Almost a year ago, the buzz during the downturn was that the economic stimulus will help boost jobs in a sort of national improvement program reminiscent of the 1930s. Our coal would be phased out. Our grids would get smart. Our cars would get hybridized.

A study provides new information about the rates at which three of the most powerful greenhouse gases are destroyed by a chemical reaction that takes place in the upper atmosphere.

Real-life applications are slowly emerging from the world of carbon nanotube research. Engineers in Iran report having designed an electrode made from graphite and PTFE carbon nanotubes to function as a cathode. Through electrolysis and hydrogen peroxide production via this cathode, colorants were quickly removed from water.

Some of the young amphibians in a Univ. of Wyoming lab have been engineered to light up in response to metals. Others fluoresce when exposed to pollution from plastic. Better still, the glowing tadpoles indicate whether pollution exists in a form that can be absorbed by an organism.

A discovery by scientists at the University of East Anglia could contribute to the development of systems that use domestic or agricultural waste to generate clean electricity. The researchers have demonstrated for the first time the mechanism by which some bacteria survive by "breathing rocks". The findings could be applied to help in the development of new microbe-based technologies such as fuel cells, or ‘bio-batteries’, powered by animal or human waste.
