In the developed world, we’ve reaped the benefits of refrigeration for more than a century, but the costs are catching up with us. We’ve eroded our connection to our food and redefined what “fresh” means. More important, refrigeration is one of the leading contributors to climate change. As the developing world races to build a US-style cold chain, Twilley asks: Can we reduce our dependence on refrigeration? Should we?

Raging ambition. Towering egos. Competition under a veneer of courtesy. Heroic effort combined with plagiarism, theft, exaggeration, and fraud. This was the state of bird study in eastern North America during the early 1800s, as a handful of intrepid men raced to find the last few birds that were still unknown to science. The most famous name in the bird world was John James Audubon, who painted spectacular portraits of birds. But although his images were beautiful, creating art was not his main goal. Instead, he aimed to illustrate (and write about) as many different species as possible.

Sweating may be one of our weirdest biological functions, but it’s also one of our most vital and least understood. In The Joy of Sweat, Sarah Everts delves into its role in the body - and in human history. Everts’ entertaining investigation takes listeners around the world - from Moscow, where she participates in a dating event in which people sniff sweat in search of love, to New Jersey, where companies hire trained armpit sniffers to assess the efficacy of their anti-sweat products. Along the way, Everts traces humanity’s long quest to control sweat.

On the morning of March 27, 1995, four quick shots cracked through Milan’s elegant streets. Maurizio Gucci, heir to the fabulous fashion dynasty, had been ambushed, slain on the steps to his office by an unknown gunman. Two years later, Milan’s chief of police entered the sumptuous palazzo of Maurizio’s ex-wife, Patrizia Reggiani - nicknamed “the Black Widow” by the press - and arrested her for the murder. Did Patrizia kill her ex-husband because his spending was wildly out of control? Or is it possible Patrizia didn’t do it at all?

When NASA sent astronauts to the moon in the 1960s and 1970s the agency excluded women from the corps, arguing that only military test pilots—made up exclusively of men—had the right stuff. It was an era in which women were steered away from jobs in science and deemed unqualified for space flight. Eventually, though, NASA recognized its blunder and opened the application process to a wider array of hopefuls, regardless of race or gender. From a candidate pool of 8,000 six elite women were selected in 1978—Sally Ride, Judy Resnik, Anna Fisher, Kathy Sullivan, Shannon Lucid, and Rhea Seddon.
