Recently, the US Food and Drug Administration approved a first-of-its-kind cancer therapy to treat aggresive forms of skin cancer. It has us thinking of the long history of cancer. One of the first recorded mentions of cancer appears in an ancient Egyptian text from around 3000 B.C. And although we now know much more about how cancer begins — as a series of mutations in someone's DNA — it's a disease people are still grappling with how to cure cancers today. This episode, cancer epidemiologist Mariana Stern talks about cancer history and treatment today — plus, why some people are more prone to certain cancers and why that might matter for curing them.

Ten years ago, Flint, Mich. switched water sources to the Flint River. The lack of corrosion control in the pipes caused lead to leach into the water supply of tens of thousands of residents. Pediatrician Mona Hanna-Attisha recognized a public health crisis in the making and gathered data proving the negative health impact on Flint's young children. In doing so, she and community organizers in Flint sparked a national conversation about lead in the U.S. water system that persists today. 

Today on the show, host Emily Kwong and science correspondent Pien Huang talk about the state of Flint and other cities with lead pipes. Efforts to replace these pipes hinge on proposed changes to the EPA's Lead and Copper Rule.

10 Years After Flint, The Fight To Replace Lead Pipes Continues

NPR's Tom Dreisbach is back in the host chair for a day. This time, he reports on a story very close to home: The years-long battle his parents have been locked in with the local wild beaver population. Each night, the beavers would dam the culverts along the Dreisbachs' property, threatening to make their home inaccessible. Each morning, Tom's parents deconstructed those dams — until the annual winter freeze hit and left them all in a temporary stalemate.

As beaver populations have increased, so have these kinds of conflicts with people...like Tom's parents. But the solution may not be to chase away the beavers. They're a keystone species that scientists believe could play an important role in cleaning water supplies, creating healthy ecosystems and alleviating some of the effects of climate change. So, today, Tom calls up Jakob Shockey, the executive director of the non-profit Project Beaver. Jakob offers a bit of perspective to Tom and his parents, and the Dreisbachs contemplate what a peaceful coexistence with these furry neighbors might look like.

Beavers Can Help With Climate Change. So How Do We Get Along?

Roughly 196 million tons of fish were harvested in 2020, according to the Food and Agriculture Organization of the United Nations. The organization also notes that the number of overfished stocks worldwide has tripled in the last century.  All of this overfishing has led to the decline of entire species, like Atlantic cod.  

Enter the Monterey Bay Aquarium's Seafood Watch. It and other free guides give consumers an overview of the world of fish and seafood, helping people to figure out the most sustainable fish available to them. With the help of Life Kit's Clare Marie Schneider, we figure out how to make informed decisions about what we eating – whether that's at a restaurant or the local supermarket.

Sustainable Seafood Is All Around You — If You Know Where To Look

When the dinosaurs walked the Earth, massive marine reptiles swam. Among them, a species of Ichthyosaur that measured over 80 feet long. Today, we look into how a chance discovery by a father-daughter duo of fossil hunters furthered paleontologist's understanding of the "giant fish lizard of the Severn." Currently, it is the largest marine reptile known to scientists.

An 11-Year-old Unearthed Fossils Of The Largest Known Marine Reptile

500 million years ago, the world was a very different place. During this period of time, known as the Cambrian period, basically all life was in the water. The ocean was brimming with animals that looked pretty different from the ones we recognize today — including a group of predatory worms with a throat covered in teeth and spines. 

Researchers thought these tiny terrors died out at the end of the Cambrian period. But a paper published recently in the journal Biology Letters showed examples of a new species of this worm in the fossil record 25 million years after scientists thought they'd vanished from the Earth. One of the authors of the paper, Karma Nanglu, tells us how this finding may change how scientists understand the boundaries of time.
