Science Friday

AI is popping up in many corners of society, but how are doctors using it in their practice? We asked our physician listeners to call in, and many of you did. What we heard mirrored broad trends: that more and more doctors are using AI tools for diagnosis, paperwork, and getting up to speed on patients. But they also have concerns.

So how is AI changing medical care? And how is it affecting patients? Joining Host Flora Lichtman to sort fact from hallucination is physician-computer scientist Jonathan Chen, who’s studied the accuracy of these models and how healthcare workers use them.

Guest:

Dr. Jonathan Chen is an associate professor of medicine and director for Medical Education in Artificial Intelligence at Stanford University.

We’ve been hearing for years that climate change makes weather more extreme, and extreme weather more frequent. But what’s been more difficult to measure is exactly how climate change influences a particular weather event. For example, how much more intense was Hurricane Lala because of climate change? How much more deadly were India’s heat waves this summer? A growing field called attribution science is trying to answer questions like these.

Flora chats with climate scientist Joyce Kimutai about the field and why it's so important. Then, we hear from climate law expert Maxine Burkett about how attribution science could be used in policy, and in the courtroom, to hold emitters responsible.

Guests:

Dr. Joyce Kimutai is a climate scientist specializing in attribution science. She works for the World Weather Attribution Consortium at Imperial College London and is the principal climate scientist for the Kenya Meteorological Services.

Maxine Burkett is a professor of climate, environment, and society at Stanford University in California.

GPS is such an essential part of our lives that it’s easy to forget there was once a world without it. But, like many tech advancements of the 20th century, GPS was originally created by the U.S. military. So how did it become a part of daily civilian life? And how vulnerable is it to manipulation?

Katherine Dunn has written all about this and more in her book, “Little Blue Dot: How GPS Shaped the Modern World.”

Guest:

Katherine Dunn is a science journalist and author of “Little Blue Dot: How GPS Shaped the Modern World.”

A controversial pipeline project in Michigan has been stuck in legal limbo for years. But this month, the Michigan Supreme Court sided with environmentalists and leaned on an ancient legal framework: the public trust doctrine.

This doctrine, which dates back to the Roman Empire, says that natural resources, like water, belong to the public, and development must do no harm. Legal experts say this argument is cropping up more and more in climate and environmental lawsuits. Joining Flora to get into the details are environment reporter Vivian La, and law professor Oday Salim.

Guests:

Vivian La is the climate solutions reporter for Interlochen Public Radio and Grist in Northern Michigan.

Oday Salim is director of the Environmental Law & Sustainability Clinic and a co-director of the Environmental and Energy Law Program at the University of Michigan Law School.

When the James Webb Space Telescope started sending back images in 2022, something mysterious appeared: little red dots, speckled across the sky. They didn’t look like any known celestial objects, and astronomers began racing to figure out what they were.

There was a lot of hot debate, but researchers are making progress—the dots appear to be black holes, but black holes like we’ve never seen them before. In a recent study, astrophysicist Rohan Naidu and his team looked into one little red dot with the catchy name of MoM-BH*-1 and concluded it was a new cosmic category called a black hole star.

Guest:

Dr. Rohan Naidu is an assistant professor at the Institute for Astronomy at the University of Hawaiʻi.

Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
