Science Friday

AI safety has dominated the news cycle for weeks, precipitated in part by an AI attack where a bunch of OpenAI’s agents teamed up and hacked another AI platform, Hugging Face, without humans knowing. Since then, multiple AI researchers have come forward to say they’re worried this tech is unsafe.
It seems every day there’s a new development: another warning from an AI researcher, an admission from a top lab that their AI systems breached another company, reassurances from CEOs. AI safety is even on the agenda for the UN General Assembly meeting this week. So how do we make sense of what’s happening in AI research right now?
Flora sits down with two researchers focusing on the engineering of AI safety: Andrea Lincoln, who studies how to mathematically understand the internal processes of AI models; and cryptographer Vinod Vaikuntanathan, who researches trust and security concerns in AI models.
GUESTS:
Dr. Vinod Vaikuntanathan is a cryptographer at MIT and a founding member of the Institute for Responsible Superintelligence.
Dr. Andrea Lincoln is a professor of computer science at Boston University and an advisory board member for The Alignment Project at the AI Security Institute.

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.

There’s a new wellness trend focused on an obscure capillary system that moves fluid around the body. Things like lymphatic walking, vibration plates, and compression boots have been touted as ways to stimulate the lymphatic system to combat bloating, flush away toxins, and generally promote health.
So what is the lymphatic system, and what does it do? And is there anything to these claims? Flora gets some answers with the help of two experts: Timothy Padera, a researcher who has dedicated his career to better understanding how the lymphatic system works; and physical therapist Marc Miller, who treats cancer patients with manual lymphatic drainage.
Guests:
Dr. Timothy Padera is an investigator at Mass General Research Institute and a professor of radiation oncology at Harvard Medical School.
Dr. Marc Miller is a certified lymphedema specialist and senior physical therapist at UT MD Anderson Cancer Center.
