The grid is an accident of history and of culture, in no way intrinsic to how we produce, deliver and consume electrical power. Yet this is the system the United States ended up with, a jerry-built structure now so rickety and near collapse that a strong wind or a hot day can bring it to a grinding halt. The grid is now under threat from a new source: renewable and variable energy, which puts stress on its logics as much as its components.

The Story of the Earth in 25 Rocks tells the fascinating stories behind the discoveries that shook the foundations of geology. In 25 chapters, Donald R. Prothero recounts the scientific detective work that shaped our understanding of geology, from the unearthing of exemplary specimens to tectonic shifts in how we view the inner workings of our planet.

Riveting and timely, a look at the research that is transforming our understanding of the cosmos in the quest to discover whether we are alone.

Bigfoot and Beyond with Cliff and Bobo is a weekly podcast hosted by Cliff Barackman and James "Bobo" Fay of Animal Planet's "Finding Bigfoot".

Coyote America is both an environmental and a deep natural history of the coyote. It traces both the five-million-year-long biological story of an animal that has become the "wolf" in our backyards and its cultural evolution from a preeminent spot in Native American religions to the hapless foil of the Road Runner. A deeply American tale, the story of the coyote in the American West and beyond is a sort of Manifest Destiny in reverse.

A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century. In 2013, Lee Berger, a National Geographic explorer-in-residence, heard of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators - men and women small and adventurous enough to be able to squeeze through eight-inch tunnels to reach a sunless cave forty feet underground. It worked.

Time rules our lives, woven into the very fabric of the universe-from the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day. Nothing so pervades our existence and yet is so difficult to explain. But now, in a series of 24 riveting lectures, you can grasp exactly why - as you take a mind-expanding journey through the past, present, and future, guided by a noted author and scientist.

Our gut is almost as important to us as our brain, yet we know very little about how it works. Gut: The Inside Story is an entertaining, informative tour of the digestive system from the moment we raise a tasty morsel to our lips until the moment our body surrenders the remnants to the toilet bowl. No topic is too lowly for the author's wonder and admiration, from the careful choreography of breaking wind to the precise internal communication required for a cleansing vomit.

Apollo is the behind-the-scenes story of an epic achievement. Based on exhaustive research that included many exclusive interviews, Apollo tells how America went from a standing start to a landing on the moon at a speed that now seems impossible. It describes the unprecedented engineering challenges that had to be overcome to create the mammoth Saturn V and the facilities to launch it. It takes you into the tragedy of the fire on Apollo 1, the first descent to the lunar surface, and the rescue of Apollo 13.

At last, science and the soul shake hands. Writing in a style that is both lucid and charming, mischievous and profound, Dr. Amit Goswami uses the language and concepts of quantum physics to explore and scientifically prove metaphysical theories of reincarnation and immortality. In Physics of the Soul, Goswami helps listeners understand the perplexities of the quantum physics model of reality and the perennial beliefs of spiritual and religious traditions.

Terence McKenna hypothesizes that as the North African jungles receded, giving way to savannas and grasslands near the end of the most recent ice age, a branch of our arboreal primate ancestors left the forest canopy and began living in the open areas beyond. There they experimented with new varieties of foods as they adapted, physically and mentally, to the environment. Among the new foods found in this environment were psilocybin-containing mushrooms.

In his articles and in best-selling books such as The Botany of Desire, Michael Pollan has established himself as one of our most important and beloved writers on modern man's place in the natural world. A new literary classic, Second Nature has become a manifesto not just for gardeners but for environmentalists everywhere.

In 1994 Professor Bryan Sykes, a leading world authority on DNA and human evolution, was called in to examine the frozen remains of a man trapped in glacial ice in northern Italy. News of both the Ice Man's discovery and his age, which was put at over 5,000 years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative?

In 1973, Norma Cobb, her husband Lester, and their five children pulled up stakes in the lower 48 and headed north to Alaska to follow a pioneer dream of claiming land under the Homestead Act. The only land available lay north of Fairbanks near the Arctic Circle where grizzlies outnumbered humans 20 to one. In addition to fierce winters and predatory animals, the Alaskan frontier drew the more unsavory elements of society's fringes. From the beginning, the Cobbs found themselves pitted in a life or death feud with unscrupulous neighbors who would rob from new settlers.

In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

Temple Grandin’s professional training as an animal scientist and her history as a person with autism have given her a perspective like that of no other expert in the field. Grandin and coauthor Catherine Johnson present their powerful theory that autistic people can often think the way animals think—putting autistic people in the perfect position to translate “animal talk.”

Why evolution is more than just a theory: it is a fact. In all the current highly publicized debates about creationism and its descendant "intelligent design", there is an element of the controversy that is rarely mentioned: the evidence, the empirical truth of evolution by natural selection.
