Ep 4. Picky Eaters/Capturing Carbon/Sea Lions and Walruses/Sangeeta Bhatia

In this episode of NOVA scienceNOW, viewers explore a variety of scientific topics, from the eating habits of picky eaters to the capture and storage of carbon dioxide to the behavior of sea lions and walruses. The episode also features an interview with Sangeeta Bhatia, a biomedical engineer who is using innovative techniques to study complex diseases such as cancer.

First up is a segment on picky eaters, which focuses on the work of Linda Bartoshuk, a scientist who has devoted her career to understanding why some people are more sensitive to certain tastes than others. Bartoshuk explains how genetics and early experiences can shape a person's taste preferences, and offers insights into how we might be able to help picky eaters expand their diets.

Next, viewers learn about the growing field of carbon capture and storage, which seeks to capture carbon dioxide emitted by power plants and other sources and store it underground. The segment explores the challenges of this technology, including the high cost and the potential risks of leaks, but also highlights some promising breakthroughs that could make it more practical and affordable in the future.

The third segment shifts focus to the animal world, where viewers are treated to an up-close look at the fascinating behavior of sea lions and walruses. Shot in stunning high-definition footage, the segment follows researchers as they travel to remote locations to study these creatures and learn more about their social structures, communication, and adaptation to changing conditions in their environment.

The episode closes with an interview with Sangeeta Bhatia, a scientist who has made groundbreaking advances in the field of cancer research. Bhatia shares insights into her work, which involves using tiny particles called nanoparticles to target and destroy cancer cells without harming healthy tissue. She also discusses the importance of diversity in science and offers advice to aspiring young researchers.

Throughout the episode, host Neil deGrasse Tyson provides engaging commentary and insights into the science behind each topic, helping viewers to better understand and appreciate the complex issues and fascinating discoveries explored in each segment. With its blend of cutting-edge research, stunning visuals, and expert analysis, this episode of NOVA scienceNOW is a must-see for anyone curious about the frontiers of science and technology.
