"Green Genes" in Yeast May Boost Biofuel Production

An effort to increase biofuel production has led scientists to discover genes in yeast that improve their tolerance to ethanol, allowing the production of more ethanol from the same amount of nutrients. This study shows how genetically altered yeast cells survive higher ethanol concentrations, addressing a bottleneck in the production of ethanol from cellulosic material (nonfood plant sources) in quantities that could compete economically with fossil fuels.

Champion Hydrogen-Producing Microbe

The cyanobacteria are famous for releasing the oxygen that made Earth the hospitable planet we know today, but some strains also have hidden talent for producing hydrogen gas. Washington University in St. Louis currently holds the gas-producing record for these versatile microbes.

Assessing the Seismic Hazard of the Central-Eastern United States

As the U.S. policy makers renew emphasis on the use of nuclear energy in their efforts to reduce the country's oil dependence, other factors come into play. One concern of paramount importance is the seismic hazard at the site where nuclear reactors are located.

Students Advise INdiana Sustainability Alliance on Green Economic Development

Mirroring an approach that Indiana has taken to the life sciences industry, the state's economic development efforts could capitalize on existing clusters of wind energy and automotive-related companies to foster a more sustainable and profitable business environment. That's the lead finding by a panel of second-year MBA students at Indiana University's Kelley School of Business, who were asked to participate in a competitive project for the INdiana Sustainability Alliance (INSA).

Researchers Engineer New Methane-Production Pathway in Microorganism

A University of Arkansas researcher and his colleagues have created the first methane-producing microorganism that can metabolize complex carbon structures, which could lead to microbial recycling of waste products and their transformation into natural gas.

Researchers Fabricate More Efficient Polymer Solar Cells

Researchers from Iowa State University and the Ames Laboratory have developed a process for fabricating more efficient polymer solar cells. The result is a polymer solar cell that captures more light and produces more power.

Great Balls of Evolution! Bacteria Cooperate in New Way

Microbiologists Derek Lovley, Zarath Summers and colleagues report in the Dec. 2 issue of Science that they've discovered a surprising new cooperative behavior in bacteria known as interspecies electron transfer. It could have important implications for the global carbon cycle and bioenergy.

Study Assesses Nuclear Power Assumptions

A broad review of current research on nuclear power economics has been published in the Journal of Renewable and Sustainable Energy. The report concludes that nuclear power will continue to be a viable power source but that the current fuel cycle is not sustainable.

A High-Yield Biomass Alternative for Making Chemicals

With a new process, chemical engineers can make valuable chemicals such as benzene, toluene and xylenes from pyrolytic oils, the cheapest liquid fuels available today from biomass. This could reduce or eliminate reliance on fossil fuels to make industrial chemicals worth an estimated $400 billion.

Study Reveals More About Biology of Energy Crop Insect

Scientists are learning more about the life stages and biology of an insect that may compete with humans for the energy crops of the future -- the insect some scientists are calling the switchgrass moth.

Optimizing Large Wind Farms

Researchers in Baltimore, MD and Belgium have developed a model to calculate the optimal spacing of wind turbines for the very large wind farms of the future. They will present their work today at the American Physical Society Division of Fluid Dynamics meeting in Long Beach, CA.

Whale-Inspired Ocean Turbine Blades

Lessons learned from the ocean's largest mammals have inspired United States Naval Academy researchers to tackle one of the serious design challenges facing a technology that uses underwater turbines to convert ocean tides into electricity -- work present today at the American Physical Society's Division of Fluid Dynamics (DFD) meeting in Long Beach, CA.

Enhancing the Efficiency of Wind Turbines

New ideas for enhancing the efficiency of wind turbines are being presented today at the American Physical Society Division of Fluid Dynamics meeting in Long Beach, CA. These include a new type intelligent system for turbines operating under many different wind conditions and a way to reduce drag on turbine blades by covering them with tiny grooves.

Should Airplanes Look Like Birds?

Airplanes do not look much like birds, but should they? This question is exactly what a pair of engineers in California and South Africa inadvertently answered recently in experiments they describe today at the American Physical Society Division of Fluid Dynamics meeting in Long Beach, CA.

Cement-Like Creation Could Help the Environment

A cement-like substance could help with stormwater management while potentially keeping millions of plastic bottles out of landfills.

New APS Report: Developing Energy Storage Technologies Among Crucial Steps Toward Increasing Renewable Electricity on Nation's Grid

U.S. policymakers must focus more closely on developing new energy storage technologies as they consider a national renewable electricity standard, according to one of the principal recommendations in a newly released report, Integrating Renewable Electricity on the Grid, by the American Physical Society's Panel on Public Affairs (POPA). Establishing a national renewable electricity standard will help to unify the fragmented U.S. grid system--an important step in the wider adoption of using more wind and solar for energy generation.

More accurate simulations could lead to "break-even" fusion in foreseeable future

Global Warming Reduces Available Wind Energy

A switch to wind energy will help reduce greenhouse gas emissions -- and reduce the global warming they cause. But there's a catch, according to a paper in the Journal of Renewable and Sustainable Energy: rising temperatures decrease wind speeds, making for less power bang for the wind turbine buck.
