GENE PATENTING: Gene patenting is widely accepted throughout the world, but many countries limit the scope of those patents. In June, the U.S. Supreme Court ruled that naturally occurring genes, whether human, animal, plant or microbial, are no longer patent-able. But, this decision does not rule out gene patenting in the U.S. altogether. A discussion with Derek Bambauer, associate law professor at the UA's College of Law, about the legal side of the issue.

GENETIC TESTING: A few decades ago, people wouldn't had been able to use a simple blood test or cheek swab to identify genes or gene mutations that can create potentially deadly illnesses, such as cancer. As access to genetic testing grows, more people have a chance to possibly prevent these.

PERSONALIZED MEDICINE: Thanks to genetic research, the 'one-size-fits-all' approach to medical care is being replaced with personalized medicine, a new method that can better diagnose a person's disease, and identify treatments that would be more successful and have less side effects.
