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.
