Super Yeast Turns Pine into Ethanol

A research team from the University of Georgia has developed a "super strain" of yeast that can efficiently ferment ethanol from pretreated pine - one of the most common species of trees in the U.S. Their research could help biofuels replace gasoline as a transportation fuel.

Jet Fuel of the Future

With the DOE, Virent, Inc., and the National Renewable Energy Laboratory (NREL) working together, planes may soon take to the skies using less petroleum. In June, DOE announced an award of up to $13.4 million dollars to Virent and its partners to develop a process to cost effectively convert cellulosic biomass - in this case the non-edible parts of corn - into jet fuel.

Adapted Antennas Harness More Power From the Sun

A research team from Tel Aviv University is working on a solar panel composed of nano-antennas instead of semiconductors. By adapting classic metallic antennas to absorb light waves at optical frequencies, a much higher conversion rate from light into useable energy can be achieved.

Photosynthesis Helper Protein Discovered

Photosynthesis is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from Germany's Max Planck Institute of Biochemistry (MPIB) have now identified a helper protein for photosynthesis in red algae.
