In this videocast, Dr. Baggish talks about his group's latest research, in which the athletes are studied during actual periods of exercise, allowing researchers to assesses the heart's ability to function under conditions of increased blood pressure and volume.

When removing a cancerous tumor, surgeons must carefully determine what tissue to remove, and this can be a time-consuming process that requires a pathologist's analysis. Researchers in Germany are developing a method that combines electrosurgery with mass spectrometry to dramatically reduce the time spent identifying tissue. Watch this videocast to find out how it works.
