World leaders have gathered in Egypt this week to begin climate talks at the 27th Conference of the Parties. However, there are still outstanding questions about who should pay for climate change losses and damages. Vulnerable countries hit hardest by climate change are asking the wealthier countries most responsible for these damages for compensation.
Climate change correspondent Lauren Sommer joins Emily Kwong to talk about this debate — and the case one island nation is making to seek payment.

In 1859, Charles Darwin published On the Origin of Species, a book about the evolution of non-human animals by natural selection.In its wake, a political idea arose — eugenics. Reading Darwin's book, Sir Francis Galton proposed that humans should be bred to give more "suitable" characteristics a "better chance of prevailing." Today, producer Rebecca Ramirez talks to Adam Rutherford about his new book, Control: The Dark History and Troubling Present of Eugenics, which traces the inextricable link between political ideology and science, and the enduring shadow of eugenics.

Katie Wu is a cat person. She has two of them: twin boys named Calvin and Hobbes. But up until grad school, she couldn't be anywhere close to a cat without her throat tightening and her nose clogging up. In a stroke of luck, Katie's cat allergy suddenly disappeared. The reasons for her night-and-day immune overhaul remain a mystery.
In this episode, Katie walks host Aaron Scott through the dynamic world of allergies and what it reveals about our immune systems. Calvin and Hobbes make cameo appearances.

Pacific lamprey have lived on Earth for about 450 million years. When humans came along, a deep relationship formed between Pacific lamprey and Native American tribes across the western United States. But in the last few decades, tribal elders noticed that pacific lamprey populations have plummeted, due in part to habitat loss and dams built along the Columbia River. So today, an introduction to Pacific lamprey: its unique biology, cultural legacy in the Pacific Northwest and the people who are fighting to save it. (Encore)

Halloween calls to mind graveyards and the walking dead, so, naturally, Short Wave wanted to know what happens when you donate your body to real scientists. Host Aaron Scott talked with journalist Abby Ohlheiser about their reporting trips to a Forensic Osteology Research Station and an anatomy lab to learn how donated bodies help everyone from surgeons to law enforcement to forensic archeologists do their jobs. And while this episode might not be for the squeamish, Abby says these spaces of death are not morbid. Instead, they are surprisingly peaceful. You can read Abby's full article in the MIT Technology Review.

The common box turtle is found just about anywhere in the continental United States east of Colorado. For all their ubiquity, it's unclear how many there are or how they're faring in the face of many threats—from lawn mowers to climate change to criminals. So today, science correspondent Nell Greenfieldboyce presents the researchers hunting for turtles—and for answers. They're creating a century-long study to monitor thousands of box turtles in North Carolina.

When Steve Gosser heard the song of a scarlet tanager in the woods, he knew to look for a bright-red bird with black wings. But when he laid eyes on the singer, he saw instead a dark-colored head, black-and-white body, with a splash of red on its chest. "Well, that sort of looks like a first-year male rose-breasted grosbeak," he said. The song of one bird coming out of the body of another suggested this little guy could be a rare hybrid. Gosser enlisted the help of some pros, including biologist David Toews, who conducted a genetic analysis to see if this was truly the offspring of two species that diverged 10 million years ago, and today run in very different circles. On today's episode, Gosser and Toews fill Aaron in on this avian mystery, and what hybrid animals can teach us about evolution.
