The Science of Picky Eaters - 02:00
What makes a dish taste good to some people and terrible to others? Why do many people, particularly many kids, find broccoli and spinach unbearably bitter? Neil deGrasse Tyson, whose mother says he was always a good eater, sets out to investigate the science behind our sense of taste. It turns out that genetics largely determine our taste, and specific genes may provide new excuses for picky eaters.
Smart Marine Mammals - 14:47
Scientists studying the behavior and intelligence of seals, sea lions, and other captive marine mammals at the University of California's Long Marine Lab say that these animals are challenging long-held assumptions about what makes humans different from other animals. Correspondent Ziya Tong discovers just what the researchers mean after she meets some of their gregarious pinniped students.
Profile: Sangeeta Bhatia - 25:22
Biomedical engineer Sangeeta Bhatia comes from a line of enterprising women—her mother was one of the first women in India to receive an M.B.A. With her own Ph.D. and M.D., Bhatia is a tissue engineer at MIT. She builds unique microlivers to study disease and test drugs, and her work may someday lead to artificial organs for transplant.
While a student at MIT, Bhatia started an outreach program to get girls into labs—wearing spacesuits, working with lasers, and loving science. Now, as a mother, Bhatia is encouraging her two young daughters to see science as a creative, exciting endeavor.
Capturing Carbon - 36:41
How did an eighth-grader's science fair project inspire a new way to tackle rising levels of carbon dioxide in the atmosphere? Claire Lackner's father Klaus, a geophysicist at Columbia University, had a brainstorm after he saw how Claire used an aquarium pump to capture carbon dioxide in the air. A decade later, Dr. Lackner is testing a product inspired by his daughter's vision.
Cosmic Perspective & Coming To Our Senses - 49:21
