  • This Is Your Brain On Dessert

    This Is Your Brain On Dessert
    Feb 21 2025
    Ever eat a full meal ... and find you still have room for dessert? If so, you're not alone. Sugar is a quick form of energy that many people crave — even when they're full. Today, hosts Emily Kwong and Regina G. Barber dive into a new study on the neural origins of the "dessert brain."

  • Party In Peru: New Critters Just Dropped

    Party In Peru: New Critters Just Dropped
    Feb 19 2025
    What happens when a team of scientists and local Awajún guides go on a 38-day trip into the Alto Mayo region of Peru? Over 2000 species are identified, of course! Tucked in this lush landscape where the Amazon basin meets the Andes mountains, were 27 species of animals previously unknown to science. It makes us wonder, what else is out there that the scientific community hasn't seen? And who already knows about it?

    Check out photos of all the critters we mentioned — and more!

  • When AI Cannibalizes Its Data

    When AI Cannibalizes Its Data
    Feb 18 2025
    Asked ChatGPT anything lately? Talked with a customer service chatbot? Read the results of Google's "AI Overviews" summary feature? If you've used the Internet lately, chances are, you've consumed content created by a large language model. These models, like DeepSeek-R1 or OpenAI's ChatGPT, are kind of like the predictive text feature in your phone on steroids. In order for them to "learn" how to write, the models are trained on millions of examples of human-written text. Thanks in part to these same large language models, a lot of content on the Internet today is written by generative AI. That means that AI models trained nowadays may be consuming their own synthetic content ... and suffering the consequences.

    View the AI-generated images mentioned in this episode.
