By day, Jess Wade is an experimental physicist at Imperial College London. But at night, she's a contributor to Wikipedia — where she writes entries about women and POC scientists. She chats with Emily Kwong about how Wikipedia can influence the direction of scientific research and why it's important to have entries about scientists from under-represented communities.

Here are the Wikipedia entries of the scientists mentioned in today's show: Sarah Gilbert, Kizzmekia Corbett, Gladys West, and of course, Jess Wade.

For nearly forty years, the Guam Rail bird (locally known as the Ko'Ko') has been extinct in the wild — decimated by the invasive brown tree snake. But the Ko'Ko' has been successfully re-introduced. It is the second bird in history to recover from extinction in the wild. Wildlife biologist Suzanne Medina tells us the story of how the Guam Department of Agriculture brought the Ko'Ko' back, with a little matchmaking and a lot of patience. (Encore episode)

Today, something special...an episode of The NPR Politics Podcast we think you might appreciate. Our colleagues take a look at Joe Biden's approach to climate and health policy.

His climate agenda will look very different than President Trump's and even President Obama's. And, on top of responding to the pandemic, the president-elect will also have to wrangle all of the other problems in the American healthcare system.

It's been more than 40 years since rocks from the moon have come back to Earth. But in late November, a Chinese craft landed on the moon's surface--it's the country's first mission designed to retrieve samples of the moon's surface. The mission is called Chang'e-5, in honor of the moon goddess. NPR science correspondent Geoff Brumfiel tells us what the mission will tell us about the solar system, and how it foreshadows China's future ambitions on Earth and in space.

The FDA has issued emergency use authorizations for two monoclonal antibody treatments for COVID-19 – one produced by Eli Lilly and another by Regeneron. As science correspondent Richard Harris explains, emergency use authorization doesn't assure that these new drugs are effective, but that their potential benefits are likely to outweigh the risks. So today, we get to the bottom of how this type of treatment works and if they'll really make a difference.
