This ancient rock is changing our theory on the origin of life | Tara Djokic

This is an episode of a podcast we think you'll love, Climate One. A third of Americans say that they've skipped food, medicine, or something else to be able to afford their energy bills. Much of the increase in the cost of electricity is driven by rising demand from artificial intelligence and data centers, industrial on shoring and hotter temperatures.How does your electricity bill get calculated, and who’s in charge of setting those rates? Does public power serve consumers better than investor-owned utilities? And will rising electricity prices dampen the transition to cleaner sources of energy?Guests:Shelley Welton, Professor of Law and Energy Policy, University of PennsylvaniaSeverin Borenstein, Professor, Haas School of Business, UC BerkeleyKevin Miller, Reporter, Maine Public Radio Hosted on Acast.

Exactly when and where did life on Earth begin? Scientists have long thought that it emerged three billion years ago in the ocean — until astrobiologist Tara Djokic and her team made an unexpected discovery in the western Australian desert. Learn how an ancient rock found near a hot volcanic pool is shifting our understanding of the origin-of-life puzzle. Hosted on Acast. See acast.com/privacy for more information.

Everyone has the right to a clean environment — but major disparities exist when it comes to who faces the consequences of pollution. Environmental justice leader Peggy Shepard points to the disproportionate impact that hazardous environmental conditions have on Black, brown and Indigenous communities and challenges us to build a truly equitable future that turns "sacrifice zones" — where community health is sacrificed for the sake of development — into "green zones" that redress the legacy of pollution and harmful policies.

Your closet is likely full of all kinds of materials — leather, cotton, nylon and polyester, to name a few — that contribute to fashion's sustainability crisis. Biomaterials investigator Dan Widmaier explains how we could look to nature for sustainable replacements for these much-used materials and introduces a leather alternative made from mushrooms that looks great and doesn't harm the environment. "We can make fashion sustainable, and we're going to do it with science," Widmaier says. Hosted on Acast. See acast.com/privacy for more information.

What if you could eat chicken nuggets without harming a chicken? It's possible through "cellular agriculture," says Isha Datar. In a talk about cutting-edge science, she explains how this new means of food production makes it possible to eat meat without the negative consequences of industrial farming — and how it could fundamentally change our food systems for the better. "It's our once-in-a-lifetime opportunity to get a second chance at agriculture," she says. Hosted on Acast. See acast.com/privacy for more information.

The single most important thing for avoiding a climate disaster is cutting carbon pollution from the current 51 billion tons per year to zero, says philanthropist and technologist Bill Gates. Introducing the concept of the "green premium" — the higher price of zero-emission products like electric cars, artificial meat or sustainable aviation fuel — Gates identifies the breakthroughs and investments we need to reduce the cost of clean tech, decarbonize the economy and create a pathway to a clean and prosperous future for all.
