This is a case study adapted from "Teaching Chemistry Through the Jigsaw Strategy" by the Quality Education Fund, Hong Kong (2007). It brings to attention the importance of chirality and the structures of molecules in a biological context. It describes the real events surrounding the drug Thalidomide before it was pulled off of the market. This drug has recently been introduced back to the market...

This segment demonstrates how cancer spreads through a mechanism called metastases, and how the puzzle of metastases inspired Dr. Folkman to identify more angiogenesis inhibitors. This is Part 6 of a 8 part series (http://www.pbs.org/wgbh/nova/cancer/program.html) that introduces a possible non-toxic cancer treatment and highlights the long journey of how angiogenesis (new blood vessel...
