Sunlight-driven CO2 fixation

The increased use of renewable energy sources, particularly sunlight, is highly desirable, as is industrial production that is as CO2-neutral as possible. Both of these wishes could be fulfilled if CO2 could be used as the raw material in a system driven by solar energy. Japanese researchers have now introduced an approach to this type of process.

Environmental impact assessment: the state of the art

In a recent issue of Impact Assessment and Project Appraisal, Richard K. Morgan of the University of Otago, New Zealand, reviews the progress of the EIA, with particular emphasis on the last 15-20 years. He also assesses whether EIA is ready for future challenges.

'Dangerous threshold' can hinder UN climate change negotiations

The identified critical threshold for dangerous climate change saying that the increase in global temperature should be below 2 degrees Celsius seems not to have helped the climate negotiations so far. New research shows that negotiations based on such a threshold fail because its value is determined by Nature. Climate negotiators should focus on other collective strategies.

Researchers find new access to abundant biomass for advanced biofuels

After cellulose, xylan is the most abundant biomass material on Earth, and therefore represents an enormous potential source of stored solar energy for the production of advance biofuels. A major roadblock, however, has been extracting xylan from plant cell walls. Researchers have taken a significant step towards removing this roadblock by identifying a gene in rice plants whose suppression improves both the extraction of xylan and the overall release of the sugars needed to make biofuels.
