Their findings, published in the open-access, peer-reviewed journal PLOS ONE, conclude that biofuel crops proposed for use in the Hawaiian Islands are two to four times more likely to establish wild populations or be invasive in Hawaii and in other tropical areas when compared to a random sample of other introduced plants.
Recent spikes in energy costs and political instability in many oil-rich regions of the world are driving a search for homegrown alternatives to traditional fossil fuels, such as coal, oil and natural gas.
Biofuel crops are often touted as a "green" solution to U.S. dependence on foreign oil and have been promoted for stimulus package "green jobs". Despite the potential benefits, researchers say biofuel crops actually might be aggressive invasive plants grown under the guise of beneficial crops.
The researchers used a weed risk assessment that examines a plant's biology, geographic origin, pest status elsewhere, and published information on its behavior in Hawaii to identify plants with a high risk of becoming invasive pests in Hawaii or other Pacific islands.
Despite these findings, researchers say some high risk biofuel crops could be grown if measures are implemented that reduce their risk of spreading out of control and causing unintended problems.
"By identifying the species with the highest risk, and pushing for planting guidelines and precautionary measures prior to widespread planting, we hope to spare the Hawaiian Islands and similar tropical ecosystems from future economic and environmental costs of the worst invaders while encouraging and promoting the use of lower risk alternative crops," said Christopher Buddenhagen, co-author of "Assessing Biofuel Crop Invasiveness: A Case Study."

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
