Last month, Vice President Joe Biden unveiled his plan for climate change—a sweeping $2 trillion dollar platform that aims to tighten standards for clean energy, decarbonize the electrical grid by 2035, and reach carbon neutrality for the whole country by 2050. Biden’s plan, like the Green New Deal, purports to create millions of jobs at a time when people are reeling financially from the pandemic—proposing employment opportunities including retrofitting buildings, converting electrical grids and vehicles, and otherwise transforming the country into an energy efficient, emissions-free economy.

But are the foundations of this plan on solid scientific ground? Yes, say Ira’s guests, political scientist Leah Stokes and energy systems engineer Sally Benson. Stokes and Benson run through Biden’s proposals, explaining what’s ambitious, what’s pragmatic, and what people might show up to vote for.

Deep in the largest rainforest of Latin America is the Peruvian Boiling River, a name earned from water that can reach 100°C—or about 212°F. 

While the river is hot enough to cook any animal unfortunate enough to wind up in it, its microbes don’t mind. They can handle the heat—and their odd survival mechanisms might have medicinal value. 

Joining Ira to talk about these tiny heat-seekers and the Peruvian Boiling River is Rosa Vásquez Espinoza, a Ph.D. candidate in chemical biology at the University of Michigan. 

See photos and video of Rosa Vásquez Espinoza’s expedition to the Boiling River and learn more about her research on extreme microbes in a feature article on SciFri. 

It’s been a busy week for science news. Cities are still grappling with COVID-19, and in New York City, previously the country’s largest coronavirus hotspot, health commissioner Oxiris Barbot has resigned. She cited Mayor Bill de Blasio’s handling of the pandemic as her reason for doing so, issuing a scathing statement on her way out the door. Barbot is just one of the many health officials around the country who have butted heads with the politicians that oversee them during the pandemic.

And across the world, devastating explosions in Beirut, Lebanon have injured thousands and killed several dozen. As officials piece together why this happened, they’re pointing to a warehouse of ammonium nitrate as the source of the blasts. 

Joining Ira to talk about these stories, and other science news of the week, is Sophie Bushwick, technology editor at Scientific American in New York, New York.
