AI-powered chatbots and image generators are changing tech interaction, but at a high environmental cost. Data centers for these models require huge amounts of electricity and water. The CEO of OpenAI seeks $7 trillion for AI chip production. Dr. Jesse Dodge discusses the energy usage of AI models and potential regulations needed. The podcast explores the impact of AI data centers on the environment and the challenges of improving efficiency in AI systems.

Scientists discuss how the number and symmetry of flight feathers can determine if a dinosaur could fly. French cheeses like Camembert and brie are at risk of extinction due to a lack of microbial diversity. The consistency of cheese flavors and colors over time poses a threat to traditional cheese-making practices.

Climate scientist Michael Mann discusses his defamation case victory against two conservative writers, highlighting the importance of defending scientists' integrity. The podcast also delves into shifting public opinions on climate change, the significance of constructive criticism in science, and the urgency for action in addressing human-caused climate change.

On this week's podcast, Odysseus, the spacecraft heading towards the moon, is discussed. If successful, it will be the first US spacecraft to land on the moon since the Apollo mission. Other topics include detecting methane leaks from space, the development of lithium-sulfur batteries, a treatment for frostbite, 'heart-on-a-chip' devices, a frog with a mushroom growing out of its leg, and estimating the population size of Skywalker gibbons through their love songs. The podcast also covers the ongoing cleanup efforts at a chemical spill site in East Palestine, Ohio.

Andy Cohen and Diane Hoskins, co-CEOs of Gensler, discuss how design can help communities adapt to global crises, including the pandemic, climate change, and social injustice. They explore changes in gathering design due to COVID-19, the impact of transitioning to electric cars on transportation design, and the importance of multimodal infrastructure and prioritizing pedestrians in city design.

The hosts discuss sonification of space data, the connection between humanities and astrophysics, using sound to convey scientific information, the multi-dimensional nature of the universe, and favorite space sounds.

Colorectal cancer rates are increasing in young people without typical risk factors, and a nurse practitioner shares warning signs and the importance of early screening. The podcast also explores teaching an AI model language by observing a child's experiences through a camera strapped to their head, highlighting challenges and surprising associations. The rising rates of colorectal cancer are discussed further, examining possible causes such as diet, lifestyle choices, and obesity. The podcast emphasizes the significance of spreading awareness about colorectal cancer and gut health through social media.
