Science Issues 2016: Trump vs. Clinton

This article was originally posted on RealClearScience.

The 2016 presidential election has been conspicuously light on substance, particularly on matters of science and policy. In an effort to provide some clarity to voters who place an emphasis on science, we have created a chart that scores the presumptive Republican and Democratic Party candidates on key scientific issues. Please keep in mind three major caveats. Continue reading

Will Propane-Making Bacteria Revolutionize Energy?

This article was originally posted on RealClearScience.

Propane is the fossil fuel of red-blooded Americans. What poolside or tailgating experience would be complete without firing up the gas grill and torching some meat? (I know, I know… there are charcoal devotees out there.) Even metropolitan mass transit systems are getting in on the excitement. Fleets of buses that run on “LPG” (liquefied petroleum gas) are burning a mixture of propane and butane.

Currently, propane is extracted from natural gas or crude oil. But, in the long run, this is neither a sustainable nor an environmentally friendly practice. Burning propane extracted from the earth is also not carbon-neutral, though it is better than combusting oil or coal. Thus, researchers are looking for ways to produce renewable “fossil fuels” through the use of alternative technologies, such as synthetic biology. Last year, for instance, scientists engineered E. coli to churn out a biofuel that resembled gasoline. Continue reading
