Nevada researchers trying to turn roadside weed into biofuel

Three decades ago, a University of Nevada researcher who obtained one of the first U.S. Energy Department grants to study the potential to turn plants into biofuels became convinced that a roadside weed—curly top gumweed—was ...

New step towards producing cheap and efficient renewable fuels

A significant advance has been made in the potential to produce renewable fuels from excess atmospheric carbon dioxide (CO2), with the discovery of a cheap and efficient catalyst with which to carry out this process.
