The Big Ratchet is the story of the ratchets: the technologies and innovations, big and small, that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket. Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened.

From rainforests to deserts, mountains to plains, the sea to the sky, animals raise their voices in an eclectic and thrilling chorus. This collection celebrates the unique calls of the keel-billed toucan, the morning roar of the Guatemalan howler monkey, the seriously social laughing of the spotted hyena Guatemalan coatimundi, the honk of the courtship-crazed hammerhead bat, sophisticated conversation from the Central African forest elephant, the subtle bellow of the great plains bison, and many more intriguing sounds.

It happens everywhere: offices, schools, even your own backyard. And, seemingly, anything can trigger it: cell phones, sirens, bad music, constant distractions, your boss, or even your spouse. We all know certain things get under our skin. Can science explain why? NPR's Joe Palca and Flora Lichtman take you on a scientific quest through psychology, evolutionary biology, anthropology, and other disciplines to uncover the truth about being annoyed.

The NPR Sound Treks series brings the outdoors to life with outstanding audio documentaries, stories, and commentary from the NPR archives.

Norman MacLean spent the last 14 years of his life determined to sift through grief and controversy in search of the truth behind the Mann Gulch tragedy, one of the worst disasters in the history of the Forest Service. Young Men and Fire is the culmination of his investigations. It is a story about honor, death, compassion, and the human spirit.

Are birds monogamous? Why do kookaburras laugh? Is the ivory-billed woodpecker really extinct? These fascinating stories feature the delightful and exotic sounds of birds, plus astute and informative commentary from bird lovers, bird experts, and sometimes birds themselves. Learn how naturalist F. Schuyler Matthews translated bird song into musical notes. Discover how the city of Chicago has drawn purple martins back to Lake Michigan, their historic habitat.

Thanks to the popularity of personal genetic testing services, it's now easier than ever to get information about our own unique DNA - but who does this information really benefit? And, as genome editing and gene therapy transform the healthcare landscape, what do we gain - and what might we give up in return?

Wherever there are people, there are penises. And even though men always carry their penis with them, we might not know it as well as we think.... Members Club is a fascinating and important exploration of the penis written by leading urologist Piet Hoebeke.

Is the five-second rule legitimate? Are electric hand dryers really bacteria blowers? How gross is backwash? When it comes to food safety and germs, there are as many common questions as there are misconceptions. And yet there has never been a book that clearly examines the science behind these important issues - until now.

Twenty meters below water, the oceanographer François Sarano came face to face with a five-and-a-half-meter great white shark. Seduced by the gentle elegance of this majestic creature, Sarano experienced a profound sense of affinity with her as they swam side by side, shoulder to shoulder, eye to eye, cutting a single figure through the ocean depths. It was an experience which made him realize the depth of our ignorance of the lives of sharks, leading him to become a passionate advocate for their protection.

We know much about our history from bones and DNA, but these studies do not tell us about the characteristics that are not preserved in the fossil record―the fleshy parts and behaviors. Looking Down the Tree applies evolutionary principles to understand the history of our species and the pressures of natural selection which led to our unique appearance and behaviors. Cruzan draws upon evidence from fossils, genomics, phylogenetics, coalescence theory.

Microfluidics is the field of science that studies fluids constrained to spaces that are smaller than one millimeter wide, and by extension, the engineering field which builds devices that exploit the unique properties of fluids at these scales. Author Albert Folch explores this micro science which has inspired engineers to build devices such as engines, spray cans, ballpoint pens, inkjet and 3D printers, pregnancy and Covid tests, glucometers, asthma nebulizers, kidney dialysis machines, and DNA analyzers.

At the heart of Israel Rosenfield and Edward Ziff's inquiry is the nature of brain function. The sensory world is disordered and chaotic. There are no labels for tables, chairs, or airplanes, and indeed there are no colors, sounds, or smells, only photons, airwaves, odorant molecules, and so on, which are unlabeled and impossible to "know." To make sense of this chaos, the brain must simplify the sensory inputs by creating, or inventing, the colors, sounds, smells, forms, and faces that are perceived in consciousness, which become a proxy for the chaotic world in which we live.

Journalist Marguerite Holloway arrives at the Women's Tree Climbing Workshop as a climbing novice, but with a passion for trees and a deep concern about their future. Run by twin sister tree doctors Bear LeVangie and Melissa LeVangie Ingersoll, the workshop helps people develop impressive technical skills and ascend into the canopy.

The last decade has seen an explosion of urban beekeeping in the US, Canada, and Europe, a well-intentioned response to perceived threats to the global honey bee population. Many thousands of people have taken up this seemingly environmentally friendly hobby, tending backyard and rooftop hives (or paying a company to do so) and encouraging honey bees to make honey and pollinate flowers. What could be wrong with that? Quite a lot, in fact. In The Honey Trap, scientist and author Dana Church demonstrates that despite reports to the contrary, honey bees are nowhere near extinction.
