In this video segment adapted from NOVA scienceNOW, learn how one species of bacteria, which is harmless to most people, has evolved to become deadly to others. The bacterium, known as Acinetobacter baumannii in medical science, and as "Iraqibacter" ...to soldiers both in and returning from Iraq, has developed resistance to even the strongest of antibiotics. Iraqibacter's genome reveals that much of its resistance has been acquired from other bacteria species through a process known as horizontal gene transfer. The video also examines how scientists may be able to prevent the bacteria from infecting humans. Closed captioning included. Run time 05:13.

This video segment adapted from NOVA scienceNOW examines the threat of a virus being spread from birds to humans, and then from humans to humans. It details the mechanisms viruses use to infect cells, and explores how mutations in a virus may change ...its virulence and how it can spread. It also looks at work being done with a re-created flu virus—from the deadly 1918 strain—that may help prevent future flu pandemics. Closed captioning included. Run time 05:08.

This video produced by Teachers' Domain features Cathy Drennan, Professor of Chemistry and Biology at the Massachusetts Institute of Technology. Cathy explains that her research focuses on microorganisms that live off carbon dioxide, one of several g...reenhouse gases that are widely believed to accelerate global warming. Specifically, Cathy is investigating how a protein inside these microorganisms converts carbon dioxide into energy. Ultimately, Cathy hopes humans might apply what they learn from microorganisms to remove carbon dioxide from the environment. Closed captioning included. Run time 02:48.
