For many of us, it's the fuel that wakes us up and gets us started on our day. Now, University of Cincinnati researchers are discovering that an ingredient in our old coffee grounds might someday serve as a cheaper, cleaner fuel for our cars, furnaces and other energy sources.

Read moreAlready noted for saving gasoline and having zero emissions, electric cars have quietly taken on an unlikely new dimension - the ability to reach blazing speeds that rival the 0-to-60 performance of a typical Porsche or BMW, and compete on some race courses with the world's best gasoline-powered cars, an authority said here today at a major scientific conference.

Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution. But a new Stanford University study finds that when you factor in the energetic costs, grid-scale batteries make sense for storing surplus solar energy, but not for wind.

Read moreNew research from the University of East Anglia shows that rising ocean temperatures will upset natural cycles of carbon dioxide, nitrogen and phosphorous. Plankton plays an important role in the ocean's carbon cycle by removing half of all CO2 from the atmosphere during photosynthesis and storing it deep under the sea. Findings published today in Nature Climate Change reveal that water temperature has a direct impact on maintaining the delicate plankton ecosystem of our oceans.

Read moreTwenty five years ago, the German chemist Michael Braungart developed a new approach to recycling, now called 'Cradle to Cradle' or C2C after the book, Cradle to Cradle: Remaking the Way We Make Things, which he and the American architect William McDonough published in 2002. Their basic idea is that the recycling process should start with the initial design of products.

Although microbes that live in the so-called "dark ocean"-- below a depth of some 600 feet where light doesn't penetrate-- may not absorb enough carbon to curtail global warming, they do absorb considerable amounts of carbon and merit further study, according to a University of Iowa study.
