Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Now, a study by researchers at the US Department of Energy (DOE) Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has found that energy sorghum ( Sorghum bicolor ) behaves more like miscanthus in the way it efficiently captures light and uses water to produce abundant biomass.

Study associates long-term exposure to air pollution with increasing emphysema

Green Car Congress

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. The annual averages of ozone levels in study areas were between about 10 and 25 ppb.

Large-scale study finds decline in ovarian reserve related to PM and NO2 in atmosphere

Green Car Congress

A large-scale study has found that high levels of air pollution adversely effect ovarian reserve—a term widely adopted to reflect the number of resting follicles in the ovary and thus a marker of potential female fertility. Some studies have tried to make the connection between ovarian reserve (i.e., —Professor La Marca.
