What happens when AI moves beyond convincing chatbots and custom image generators to something that matches—or outperforms—humans?Each week, tech companies trumpet yet another advance in artificial intelligence, from better chat services to image and video generators that spend less time in the uncanny valley. But the holy grail for AI companies is known as AGI, or artificial general intelligence—a technology that can meet or outperform human capabilities on any number of tasks, not just chat or images.The roadmap and schedule for getting to AGI depends on who you talk to and their precise definition of AGI. Some say it’s just around the corner, while other experts point a few years down the road. In fact, it’s not entirely clear whether current approaches to AI tech will be the ones that yield a true artificial general intelligence.Hosts Ira Flatow and Flora Lichtman talk with Will Douglas Heaven, who reports on AI for MIT Technology Review; and Dr. Rumman Chowdhury, who specializes in ethical, explainable and transparent AI, about the path to AGI and its potential impacts on society.Transcripts for each segment will be available after the show airs on sciencefriday.com.

In many parts of the United States, spring has sprung. There’s nothing quite like those first few beautiful days of spring. They’re delightful—until the sneezing starts.According to the CDC, a quarter of US adults deal with seasonal allergies. And if you think they’re getting worse, it’s not just in your head. Previous research has shown that climate change is making pollen seasons start earlier and become more intense, a problem that’s expected to get worse.Joining Host Ira Flatow to discuss the science behind seasonal allergies, and the best methods for treating them, is Dr. Neeta Ogden, director of the Allergy, Asthma and Sinus Center in Edison, New Jersey.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Over the past two decades, rates of peanut allergies in children have more than tripled. A variety of theories has been proposed to explain this, from a rise in industrialization keeping kids away from the germs that develop the immune system, to the previous pediatric guidelines that urged parents to restrict access to peanuts early in life. Whatever the cause, higher rates of peanut allergies means effective treatments are in higher demand.New research published in NEJM Evidence shows that a simple treatment could be effective for kids who can tolerate half a peanut or more before an overwhelming reaction: eating a small amount of store-bought peanut butter, gradually increasing the amount over 18 months. In the study, 100% of participating kids increased their tolerance to three tablespoons of peanut butter without an allergic reaction.Joining Host Flora Lichtman to discuss this study and other food allergy treatments on the horizon is Dr. Scott Sicherer, Director of the Jaffe Food Allergy Institute at Mount Sinai Hospital in New York.Transcripts for each segment will be available after the show airs on sciencefriday.com.
