Cancer Immunotherapy, Raccoons, Frog Calls. Dec 14, 2018, Part 1

For years, cancer treatment has largely involved one of three options—surgery, radiation, or chemotherapy. In recent years, however, a new treatment option, immunotherapy, has entered the playing field. It has become the first-line preferred treatment for certain cancers. Immunotherapy is a class of treatments that use some aspect of the body’s own immune response to help battle cancer cells. There are several different approaches, each with their own advantages and weaknesses.This year, the 2018 Nobel Prize in Physiology or Medicine was awarded jointly to James P. Allison and Tasuku Honjo “for their discovery of cancer therapy by inhibition of negative immune regulation.” The Nobel committee called their discoveries a landmark in our fight against cancer. Treatments based on their work are now in use against several forms of cancer, with many more trials underway.

How do raccoons keep getting into people’s trash? It might just be one of the greatest unsolved mysteries of our time. No matter what kind of fancy lid, bungee cord, or alarm system we use, somehow these masked creatures always find a way into our smelly garbage. But are they just dexterous or actually smart? Lauren Stanton, Ph.D. candidate in the Animal Behavior and Cognition Lab at the University of Wyoming, joins Ira to talk about testing the animal’s smarts.

City mouse and country mouse aren’t just characters from stories—cities are unique ecosystems built by humans, and animals adapt when they move into urban areas. Researchers recently compared the calls of male túngara frogs in Panama that lived in the forest with those in the city. They found that the city frogs had more complex calls and that female frogs preferred these calls—but the less complex calls of country frogs made them easier to hide from predators. Biologist Alex Trillo, an author on the study, talks about the costs and benefits of changing calls for the túngara frog.
