This activity utilizes the emergence of antibiotic resistance, and mechanisms thereof, to teach essential concepts including natural selection, bacterial gene transfer, mutation, and gene expression. It also provides a connection between course content and modern applications of important concepts. The activity (app. 25 minutes) is intended for introductory students in biology. It is flexible and...
In this activity, students are exposed to some of the most significant biomolecules currently exploited by technology and identify their natural origins. They also explain the significance of the roles these biomolecules play in nature, as well as for humans. Specifically, students work to develop a logical process for a real-life application of biotechnology (insulin production) using knowledge...
This segment shows how Dr. Judah Folkman gained his insight of angiogenesis, and how the biological field disagreed the existence of angiogenesis.
This is Part 2 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 growth) was discovered, how most...
This segment illustrates how Dr. Judah Folkman designed experiments to provide solid proof of angiogenesis' existence, and the further identification of angiogenesis factors. The identification of angiogenesis factors was so time consuming (it took several years of effort) that even Dr. Folkman doubt whether this factor existed. The quote from Dr. Folkman: "In research, there's a very fine line...
This segment shows the other approach of searching and identifying angiogenesis inhibitors.
This is Part 5 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 growth) was discovered, how most scientists thought angiogenesis as ridiculous, how...
