Breast Cancer Cultural History, Butterfly Wings. Jan 31, 2020, Part 2

‘Radical’ Explores The Hidden History Of Breast Cancer 

Nearly 270,000 women are diagnosed with breast cancer every year, along with a couple thousand men. But the disease manifests in many different ways, meaning few patients have the same story to tell. 

Journalist Kate Pickert collects many of those stories in her book Radical: The Science, Culture, and History of Breast Cancer in America. And one of those stories is her own. As she writes about her own journey with breast cancer, Pickert delves into the history of breast cancer treatment—first devised by a Scottish medical student studying sheep in the 1800s—and chronicles the huge clinical trials for blockbuster drugs in the 80s and 90s—one of which required armies of people to harvest timber from the evergreen forests of the Pacific Northwest. 

She joins Ira Flatow to tell her story, and the surprising cultural history of breast cancer. 

With Butterfly Wings, There’s More Than Meets The Eye 

Scientists are learning that butterfly wings are more than just a pretty adornment. Once thought to be made up of non-living cells, new research suggests that portions of a butterfly wing are actually alive—and serve a very useful purpose. 

In a study published in the journal Nature Communications, Naomi Pierce, curator of Lepidoptera at the Harvard Museum of Comparative Zoology, found that nano-structures within the wing help regulate the wing’s temperature, an important function that keeps the thin membrane from overheating in the sun. They also discovered a “wing heart” that beats a few dozen times per minute to facilitate the directional flow of insect blood or hemolymph. 

Pierce joins Ira to talk about her work and the hidden structures of butterfly wings. Plus, Nipam Patel, director of the Marine Biological Laboratory, talks about how butterfly wing structure is an important component of the dazzling color on some butterfly wings.
