Researchers use sunlight to produce chemicals and energy

Researchers at the University of Copenhagen have discovered a natural process they describe as "reverse photosynthesis," by which the energy in solar rays breaks down plant biomass rather than building it, as is the case ...

Oxygen levels in the air do not limit plant productivity

There have been concerns that present oxygen levels may limit plant productivity. Swedish researchers at Umea University show that this is not the case in a new study published in the journal The Proceedings of the National ...

Engineered yeast could expand biofuels' reach

Boosting production of biofuels such as ethanol could be an important step toward reducing global consumption of fossil fuels. However, ethanol production is limited in large part by its reliance on corn, which isn't grown ...
