Nature Conservancy study raises major questions on biofuels

02-07-2008 · EurekAlert!

A new Nature Conservancy study finds that converting land for biofuel crops results in major carbon emissions, actually worsening the problem of global warming instead of mitigating it. "This research examines the conversion of land for biofuels and asks the question 'Is it worth it?' Does the carbon you lose by converting forests, grasslands, and peatlands outweigh the carbon you 'save' by using biofuels instead of fossil fuels? And surprisingly, the answer is no,? said lead author Joe Fargione, a scientist for The Nature Conservancy.

    On the road to making biofuels more economically competitive with fossil fuels, there are significant potholes to negotiate. For cellulosic ethanol production, one major detour has being addressed with the characterization of the genetic blueprint of the fungus Pichia stipitis, by the U.S. Department of Energy Joint Genome Institute (DOE JGI) and collaborators at the U.S. Forest Service, Forest Products Laboratory. The research is featured in the March 4 advanced online publication of Nature Biotechnology.

  6. Hypertension experts clash over TROPHY study results
    03-05-2007 · EurekAlert!
    When the results of a major long-term, multicenter study, the Trial of Preventing Hypertension (TROPHY), were called into question in two editorials published in the November 2006 issue of the American Journal of Hypertension (AJH), it was inevitable that an exchange of views between the study's supporters and detractors would occur. The essential issue is whether the TROPHY data support the conclusions reported in the New England Journal of Medicine.

    Publicly funded science in America is accountable to the people and their government representatives. However, this arrangement raises questions regarding the effect such oversight has on science. It is a problem of particular relevance as the nation prepares for the end of the Bush administration, which has taken divisive stances on a number of issues, including stem cell research and global warming. Striking a balance is an essential question for Daniel Sarewitz of Arizona State University.
