Breakthrough Mathematical Model to Determine Optimal Design of Algae-Based Biorefinery

The combustion of fossil fuels drives the world's energy production, but it also emits carbon dioxide (CO2) and other greenhouse gases. In recent years, researchers have worked to cultivate alternative, renewable energy sources, including using algae-based systems.

New Model Helps Predict Impact of Changing Climate on Forests over Thousands of Years

It can take Mother Nature 1,000 years to grow a forest. But Nikolay Strigul, assistant professor of mathematics and statistics at Washington State University Vancouver, can grow one on a computer in three weeks.

MIT Economist Supports Carbon Tax to Make up for Disparity in Energy Costs

In recent years, proponents of clean energy have taken heart in the falling prices of solar and wind power, hoping they will drive an energy revolution. But a new study co-authored by an MIT professor suggests otherwise: Technology-driven cost reductions in fossil fuels will lead us to continue using all the oil, gas, and coal we can, unless governments pass new taxes on carbon emissions.

Researchers Use Microbial Fuel Cells to Generate Electricity from Wastewater

Historically, solar rays dominate the the renewable energy source market. Two researchers, Xueyang Feng and Jason He, from Virginia Tech have developed a new technique to increase the amount of electric current that can be produced from the wastewater.

Scientists Discover Genetic Diversity Enhances Productivity Yields of Switchgrass

Going down in history we find that even before farmers could settle down in the Midwestern United States and plant crops, there existed the root systems of prairie grasses, including strong-stemmed and tall switchgrass species that improved the quality of the soil, thus developing millions of acres of top-quality farmland.

University of California Commits to Emit Net Zero Greenhouse Gases by 2025

For Susanna Hecht, the future of life on this planet as we know it is a matter of degrees — a scant few at that.

New Technique to Reduce Plant Lignin Could Help Lower Biofuel Cost

Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown for the first time that an enzyme can be tweaked to reduce lignin in plants.

Newly Exposed Edges of Deforested Areas Highly Susceptible to Drastic Temperature Changes

The newly-exposed edges of deforested areas are highly susceptible to drastic temperature changes, leading to hotter, drier and more variable conditions for the forest that remains, according to new research from the University of Colorado Boulder.

High Concentration of CO2 in Soil Can Change Community of Organisms Living in Soil

A high concentration of carbon dioxide gas in the soil can change the community of organisms living in the soil in the long term. At the same time it changes processes in this ecosystem like the subterranean carbon cycle and carbon storage.

Plants and Decomposing Material in Soil Emit More CO2 than Fossil Fuels

In the concrete jungle at the core of a city, carbon dioxide (CO2) emissions are dominated by the fossil fuels burned by the dense concentrations of cars and buildings.

Shipwrecks could be Used to Monitor Health of Deep-Ocean Ecosystems

The 2010 Deepwater Horizon oil spill significantly altered microbial communities thriving near shipwrecks in the Gulf of Mexico, potentially changing these diverse ecosystems and degrading the historically and culturally significant ships they live on, according to new research being presented here. The findings are also revealing how decades-old, or even centuries-old, shipwrecks could be used to monitor the health of deep-ocean ecosystems, and the effects of oil and gas activity in the Gulf, according to the researchers.

Reducing U.S. Climate Emissions Could Prevent Pollution-Related Premature Deaths by 2030

Reducing U.S. climate emissions enough to avoid a 2-degree Celsius increase in global warming could prevent up to 175,000 pollution-related premature deaths nationwide by 2030 and generate health benefits of about $250 billion annually, according to a new analysis by researchers at Duke University and the NASA Goddard Institute for Space Studies.

Despite Reduced Sulfur Emissions, Atmospheric Sulfate Particles are Still Acidic

When acidic materials are spilled, the clean-up procedure involves adding a base chemical to neutralize the acid. Up to a point, the more base added, the more neutral and less toxic the spill becomes.

Antarctic Ice Sheets More Vulnerable to Rising Atmospheric Carbon Dioxide Than Previously Thought

Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought.

Warming Temperatures and Variable Precipitation Increase Severity of U.S. Forest Droughts

Forests nationwide are feeling the heat from increasing drought and climate change, according to a new study by scientists from 14 research institutions.
