Ready for RoundUp? Sep 01, 2021
Show notes

Today on how on earth, Beth talks to MIT scientist Stephanie Seneff about her book, Toxic Legacy. Dr Seneff takes us on a fast paced tour of the large range of toxicities produced by glyphosate. Glyphosate is the active ingredient in Roundup, the most commonly used weedkiller in the world. Nearly 300 million pounds of glyphosate-based herbicide are sprayed on farms—and food—every year. Although the herbicide is claimed
to be safe for humans, animals, and the environment, Seneff summarizes research showing otherwise.

A New Way to Measure Aging Aug 12, 2021
Show notes

This week on How on Earth, Beth talks with Professor Tom LaRocca, professor in the department of Health and Exercise Science at CSU in Fort Collins. His background is in molecular biology and physiology, but he is particularly interested in translational research (using laboratory science to develop practical applications or treatments that can help people). He is especially interested in the biology of healthspan, the period of life during which we are healthy and productive, and in research on ways to increase healthspan. He talks particularly about some of his recent work which has identified genetic marks of our biological age, as opposed to our chronological age or the number of years one has under their belt. You can see his website as well as the Healthy Aging website he and his colleagues maintain.

In this How on Earth episode, we learn about the latest research on psychedelic mushrooms (psilocybin) and their potential for treating depression. Jill Sjong speaks with Alex Kwan, a neuroscientist and Associate Professor in Psychiatry at Yale University’s School of Medicine, who studies dendritic plasticity in mice using advanced optical methods. Dr. Kwan explains how psilocybin changes the brain, how these changes last long after the psychedelic effects have worn off, and how these results may lead to future treatments for depression.

Emerging World: A Road Map for a Better World Jul 11, 2021
Show notes

Today on How on Earth, Beth speaks with author Roger Briggs about his new book: Emerging World. Briggs explores the evolution of consciousness and shows that this is behind everything humans have done, are now doing, and are capable of in the future. By bringing together knowledge from paleoanthropology, cultural philosophy, cognitive psychology, and evolutionary theory, he makes the case that humanity is now on the verge of a major transformation, a monumental turning point in our story. Emerging World offers a new understanding of our crisis today and points the way to a bright future for humanity and life on our planet. You’ll also hear about new research into the surprising role that the microbiome plays in aging fruit flies. You can find out more about Roger’s ongoing project at his website.
