Insects might make us recoil in repugnance, but they also manufacture - or make possible in other ways - many of the things we take for granted in our daily lives. When we bite into a shiny apple, listen to the resonant notes of a violin, try on the latest fashions, receive a dental implant, or get a manicure, we are mingling with the by-products of their everyday lives.

We live in a world of seeds. From our morning toast to the cotton in our clothes, they are quite literally the stuff and staff of life, supporting diets, economies, and civilizations around the globe. Just as the search for nutmeg and the humble peppercorn drove the Age of Discovery, so did coffee beans help fuel the Enlightenment and cottonseed help spark the Industrial Revolution. And from the fall of Rome to the Arab Spring, the fate of nations continues to hinge on the seeds of a Middle Eastern grass known as wheat.

Harry Cliff - a University of Cambridge particle physicist and researcher on the Large Hadron Collider - sets out in pursuit of answers. He ventures to the largest underground research facility in the world, deep beneath Italy's Gran Sasso mountains, where scientists gaze into the heart of the Sun using the most elusive of particles, the ghostly neutrino. He visits CERN in Switzerland to explore the "Antimatter Factory," where the stuff of science fiction is manufactured daily (and we're close to knowing whether it falls up).

A lifetime of adventures with bats around the world reveals why these special and imperiled creatures should be protected rather than feared.

Every one of us contains a billion times more atoms than all the grains of sand in the earth’s deserts. If you weigh 150 pounds, you’ve got enough carbon to make 25 pounds of charcoal, enough salt to fill a saltshaker, enough chlorine to disinfect several backyard swimming pools, and enough iron to forge a 3-inch nail. But how did these elements combine to make us human?

How did a simple commodity, once the prized monopoly of kings and princes, become an essential ingredient in the lives of millions, before mutating yet again into the cause of a global health epidemic? Prior to 1600, sugar was a costly luxury, the domain of the rich. But with the rise of the sugar colonies in the New World over the following century, sugar became cheap, ubiquitous, and an everyday necessity. Less than 50 years ago, few people suggested that sugar posed a global health problem.

They destroy plant diseases. They break down toxins. They plough the earth. They transform forests. They’ve survived two mass extinctions, including the one that wiped out the dinosaur. Not bad for a creature that’s deaf, blind, and spineless. Who knew that earthworms were one of our planet’s most important caretakers? Or that Charles Darwin devoted his last years to studying their remarkable achievements?

For particularly brilliant theoretical physicists like James Clerk Maxwell, Paul Dirac, or Albert Einstein, the search for mathematical truths led to strange new understandings of the ultimate nature of reality. But what are these truths? What are the mysterious numbers that explain the universe? In Fantastic Numbers and Where to Find Them, the leading theoretical physicist and YouTube star Antonio Padilla takes us on an irreverent cosmic tour of nine of the most extraordinary numbers in physics, offering a startling picture of how the universe works.

Omega-3 fatty acids have long been celebrated by doctors and dieticians as key to a healthy heart and a sharper brain. In the last few decades, that promise has been encapsulated in one of America's most popular dietary supplements. Omega-3s are today a multi-billion dollar business, and sales are still growing apace - even as recent medical studies caution that the promise of omega-3s may not be what it first appeared.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

In Mycophilia, accomplished food writer and cookbook author Eugenia Bone examines the role of fungi as exotic delicacy, curative, poison, and hallucinogen, and ultimately discovers that a greater understanding of fungi is key to facing many challenges of the 21st century.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat? Drawing on decades of research, Harvard psychiatrist Dr. Chris Palmer outlines a revolutionary new understanding that for the first time unites our existing knowledge about mental illness within a single framework: mental disorders are metabolic disorders of the brain. Brain Energy will transform the field of mental health, and the lives of countless people around the world.
