Can I Eat That? (Episode #604H)

KQED World: Fri, Jun 21, 2013 -- 7:00 AM

What are the secrets behind your favorite foods? Why are some treats - like chocolate chip cookies - delectable, while others - like cookies made with mealworms - disgusting? You may think you understand what makes something sweet, salty or bitter, but David Pogue gets a taste of a much more complicated truth as he ventures into labs and kitchens where everything from apple pie to Thanksgiving turkey to juicy grasshoppers is diced, sliced, dissected and put under the microscope. If scientists can uncover exactly what's behind the mouth-watering flavors and textures we take for granted every day, could they help us enjoy our food more - without packing on the pounds?

What Are Animals Thinking? (Episode #605H)

KQED World: Fri, Jun 14, 2013 -- 1:00 PM

Have you ever wondered what's going on inside an Animal's head? How do they see the world -- and us? Is your dog really feeling guilty when it gives you that famous "guilty look?" Do pigeon brains possess "superpowers" that allow them to find their way home across hundreds of unfamiliar miles? David Pogue meets -- and competes -- with a menagerie of smart critters that challenge preconceived notions about what makes "us" different from "them" expanding our understanding of how animals really think.

How Smart Are Animals? (Episode #504H)

KQED World: Fri, Jun 14, 2013 -- 12:00 PM

How Smart Can We Get? (Episode #603H)

KQED World: Fri, Jun 7, 2013 -- 7:00 AM

How do you get a genius brain? Is it all in your DNA? Or is it hard work? Is it possible that everyone's brain has untapped genius - just waiting for the right circumstances so it can be unleashed? From a man who suddenly acquired an extraordinary musical gift after a freak head injury to a "memory athlete" who can remember strings of hundreds of random numbers, David Pogue meets people stretching the boundaries of what the human mind can do. Then, Pogue puts himself to the test: After high-res scanning, he finds out how the anatomy of his brain measures up against the greatest mind of the century - Albert Einstein.
