Cyanobacteria are oxygen-producing micro-organisms that are the progenitors of land plants and responsible for nearly one half of the Earth's current primary productivity. David Kehoe, associate professor of biology at Indiana University, and his research group are interested in uncovering the molecular mechanisms that control how organisms sense and respond to changes in their environment. Cyanobacteria are excellent for his group's studies because Cyanobacteria have successfully colonized nearly every type of habitat on Earth.

IU Research and Teaching Preserve Open House and Tours
Thursday, Aug. 25
1 p.m. to 4 p.m.
Located near University Lake on the Griffy Woods property, IU Bloomington
An informal open house/tour of the IU Research & Teaching Preserve (IURTP) Field Lab will be held during orientation week. Everyone is invited to stop by to learn more about the facility and the preserve. The 6,000-square-foot IURTP Field Lab is available for research, teaching and meetings.

Scientist at Work: Mark Goebl
An Indiana University School of Medicine professor and three of his former students hope to have found the secret to making a yeast product that more efficiently breaks down corn and other plants into the biofuel ethanol. Professor of biochemistry and microbiology Mark Goebl's reaserch into yeast's dietary preferences could produce a savings at the pump and change the proficiency of ethanol production.

An Indiana University scientist studying human bone growth has received a $2.6 million grant from the U.S. Department of Defense to study a chemical compound with potential to fight osteoporosis and accelerate broken bone healing. "In preliminary studies, particularly in bone fractures, we've seen an effect in as little as a week," said Hiroki Yokota, professor at Indiana University-Purdue University Indianapolis, "and the effect is even stronger in two weeks."

It seems we may have parasites to thank for the existence of sex as we know it. Indiana University biologists have found that, although sexual reproduction between two individuals is costly from an evolutionary perspective, it is favored over self-fertilization in the presence of coevolving parasites. Sex allows parents to produce offspring that are more resistant to the parasites, while self-fertilization dooms populations to extinction at the hands of their biological enemies.

A new study from the School of Science at Indiana University-Purdue University Indianapolis is among the first to investigate mercury deposits in industrialized city soil near coal-fired power plants. The study reports that measurable amounts of the mercury emitted by coal-fired power plants are deposited in local soil and subsequently enter regional watersheds, contaminating fish and making them unsafe for human consumption.
