Zeroing in on Cancer Épisode 4

One in three Japanese people will die of cancer, so it's no surprise that cancer research is one of the most important medical fields. Currently, there are three established treatments: surgery, chemotherapy and radiation therapy. But today scientists around the world are working to add a fourth: cancer vaccines. And Japanese researchers are right in the thick of it! They are identifying genes that are expressed only in cancer cells, and making vaccines from molecules called peptides that form from the breakdown of the proteins these "cancer genes" encode. We hear about patients who were treated with the vaccine-and saw amazing results. And in the studio, we have Yusuke Nakamura of the University of Tokyo Institute of Medical Science, one of Japan's leading researchers in this field.

New Frontiers in Seismic Design Épisode 13

Do you know what the most significant source of damage is to a building during an earthquake? While most people might think of the magnitude and intensity scales as a way to measure a quake's destructiveness, there is actually another important factor: an earthquake's period of oscillation. For example, during earthquakes with a long period of oscillation, tall buildings are most susceptible to damage because of a phenomenon called resonance. Studies have now begun to analyze the kind of ground cities are built upon in an effort to predict the period of earthquakes before they happen. We report on this cutting edge research protect buildings against giant earthquakes.
