The club, which has about 20 members, is researching the culture and regrowth of methanotrophic bacteria, using a wide variety of experiments and individual projects. The students meet every Thursday with their advisor, Michael Ralph, and they also work during their own time.

"We risk being in a post-antibiotic world," said Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention, referring to the urinary tract infection of a 49-year-old Pennsylvania woman who had not traveled within the prior five months. Frieden, speaking at a National Press Club luncheon in Washington, D.C., said the bacteria was resistant to colistin, an antibiotic that is reserved for use against "nightmare bacteria."

Genetically modified organisms (GMOs) or genetically engineered (GE) foods have the potential to cause a variety of health problems.  For example, they may produce new allergens and toxins, and spread harmful traits to non-GMO crops. In addition, at least one major environmental impact of genetic engineering has already reached critical proportions: overuse of herbicide-tolerant GE crops has spurred an increase in herbicide use and an epidemic of herbicide-resistant "superweeds," which will lead to even more herbicide use. The long-term impacts of GMOs are unknown, and once released into the environment they cannot be recalled.
