During the last ice age, America’s coastlines and waterways looked much different than they do today. When glaciers melted, coasts and shorelines were inundated, burying early human settlements underwater. This is where underwater archeology comes in. Donning scuba gear and trowels, researchers are finding remarkably well-preserved artifacts that tell us more about what life was like in the early Americas.

Joining Flora to talk about this is reporter Reid Frazier, who accompanied an underwater archeology team on an excursion in Lake Erie. Then, underwater archeologist Jessi Halligan talks about her discoveries at a key site in Florida.

GUESTS:

Reid Frazier is an energy reporter for The Allegheny Front in Pittsburgh, Pennsylvania.

Dr. Jessi Halligan is an underwater archeologist and associate professor at Texas A&M in College Station, Texas.

The Hawaiian Islands tend to be insulated from the worst effects of hurricanes, but this summer has been different. In mid-August, Hurricane Lala pummeled the Big Island, damaging homes and roads and causing flooding and power outages. Then a few weeks later, Hurricane Lowell hit the islands of Ni‘ihau and Kaua‘i.

What do scientists make of this hurricane season? And how is climate change playing out along Hawaiʻi’s coasts? Flora talks with Haunani Kane, who studies how climate change impacts the islands, about resilience, the importance of reefs, and combining different types of knowledge.

Guest:

Dr. Haunani Kane is an assistant professor at the University of Hawaiʻi at Mānoa studying how climate change impacts islands and island people.

A lot of things in life are squishy, including your skin, your organs, and all the goo inside you. But technology tends to be rigid and hard. Figuring out how to get those two worlds to work together can be challenging. How do you connect an electronic sensor to a soft, beating heart?

As an inventor of biocompatible electronic devices, John A. Rogers has designed things like flexible probes, a pacemaker smaller than a grain of rice, and wireless sensors that stick to skin like a temporary tattoo. He joins Host Flora Lichtman to talk about the challenges of meshing the natural and artificial worlds, and his approach to science and technology development.

Guest:

Dr. John A. Rogers is a professor and director of the Querrey-Simpson Institute of Bioelectronics at Northwestern University.
