Health officials say there's very little risk to humans from the bird flu outbreak among dairy cattle, but there's still much they don't know. Here are four questions scientists are trying to answer.
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.

Surgeons transplanted a kidney and thymus gland from a gene-edited pig into a 54-year-old woman in an attempt to extend her life. It's the latest experimental use of animal organs in humans.
The agency stressed the material is inactivated and that the findings "do not represent actual virus that may be a risk to consumers," but it's continuing to study the issue.
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.

Thousands of years ago, there was a ceremony to bind close friends together as sworn siblings. Could the practice be resurrected today to strengthen modern friendships? Two women did just that.
The map can give researchers clues to understanding tick-borne diseases, while also showing the public where they’re likely to encounter a lone star tick in the state.
Studies suggest people who take metformin for diabetes may be at lower risk for cancer, heart disease and dementia. Now researchers aim to test if it prevents age-related diseases in healthy people.
Drug company reps commonly visit doctors to talk about new medications. A team of economists wanted to know if that helps patients live longer. They found that for cancer patients, the answer is no.
