July 20, 2022 Shedding New Light on Dark Matter
Planets, interstellar gas, and stars that illuminate the night sky account for only 15% of the matter in the universe. So, how important is a “Cosmological Signature” and what is “Cosmic Microwave Background”? What does either have to do with scientists’ search for invisible, dark matter, 85% of the universe, created in the wake of the “Big Bang”? Learn more on NSFs “The Discovery Files.”

July 18, 2022 Megalodon, King of the sharks
Megalodon was a gigantic, prehistoric shark with teeth as big as a human hand that ruled the oceans 3-16 million years ago. We’ll explore the Meg’s place in the ancient food web from traces of food left behind in the fossilized enamel of their teeth and look for insights into why the Megalodon went extinct.

We are joined by researcher Dr. Emma Kast and Paleontologist Dr. Bruce MacFadden.

July 07, 2022 Protective Food Packaging
As the cost of buying groceries rises, food spoilage sends up to 40% of America’s food into landfills, and foodborne illness causes 420,000 deaths per year worldwide, could an innovative medical technology born on the battlefield be the solution? Researchers adapted that technology to develop a food packaging system that is biodegradable, protects against microbial contamination, and extends shelf life.
