The Private Healthcare Exchanges conference July 16-17 in Chicago will focus on how the Affordable Care Act is changing the way insurers sell health insurance.

This conference, expected to draw about 14,000 scientists, will feature topics ranging from chemistry’s role in establishing the innocence of people wrongly convicted of murder to a spray-on coating to keep America’s favorite fresh fruit (that’s the banana) from ripening so quickly.

The Department of Health and Human Services has revised the schedule for its four regional forums to address questions and concerns from state officials and others as the department moves forward in implementing the Patient Protection and Affordable Care Act.
