Aging - not cancer, not heart disease - is the underlying cause of most human death and suffering. The same cascade of biological changes that renders us wrinkled and gray also opens the door to dementia and disease. We work furiously to conquer each individual disease, but we never think to ask: Is aging itself necessary? Nature tells us it is not: There are tortoises and salamanders who are spry into old age and whose risk of dying is the same no matter how old they are.

To date, more than a million insect species have been described, with probably at least another 5-8 million species waiting in the wings for a name. Insects are a fascinatingly diverse and beautiful spectrum of animals. They range in size from the tiny parasitic wasp, measuring a mere 139µm, to the aptly named Titan beetle, which can reach lengths of up to 17cm. They can be found on all continents of the world, from the Sahara Desert to the frozen wastes of Antarctica. While no insects live beneath the waves, the intrepid sea skaters skim the surface of some of the world's oceans.

The egg is a paradox―both alive and not alive―and a symbol as old as culture itself. In this wide-ranging and delightful journey through its natural and cultural history, Lizzie Stark explores the egg’s deep meanings, innumerable uses, and metabolic importance through a dozen dazzling specimens. Egg is playful, informative, and guarantees that you’ll never take this delicate ovoid for granted again.

This is your informal guide to the subatomic ecosystem we’re all immersed in. In this series, we explore the taxa of particle species and how they interact with one another. Our aim is give us all a better foundation for understanding our place in the universe. The guide starts with a host of different particle species. We’ll talk about their masses, charges and interactions with other particles. We’ll talk about how they are created, how they decay, and what other particles they might be made of.

The deep-learning revolution has brought us driverless cars, the greatly improved Google Translate, fluent conversations with Siri and Alexa, and enormous profits from automated trading on the New York Stock Exchange. Deep-learning networks can play poker better than professional poker players and defeat a world champion at Go. In this book, Terry Sejnowski explains how deep learning went from being an arcane academic field to a disruptive technology in the information economy.

Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do.

Why do women live longer than men? Why do women have menopause? Why are women more likely to get Alzheimer’s? Why do girls score better at every academic subject than boys until puberty, when suddenly their scores plummet? And does the female brain really exist? In Eve, Cat Bohannon answers questions scientists should have been addressing for decades. With boundless curiosity and sharp wit, she covers the past 200 million years to explain the specific science behind the development of the female sex.

In The Language Puzzle, renowned archaeologist Steven Mithen puts forward a groundbreaking new account of the origins of language. Scientists have gained new insights into the first humans of 2.8 million years ago, and how numerous species flourished but only one, Homo sapiens, survives today. Drawing from this work and synthesizing research across archaeology, psychology, linguistics, genetics, and more, Mithen details a step-by-step explanation of how our human ancestors transitioned from apelike calls to words, and from words to language as we use it today.

The mathematician and author Steven Strogatz and the astrophysicist and author Janna Levin interview leading researchers about the great scientific and mathematical questions of our time.

Editors at The Lancet Oncology, in conversation with the journal’s authors, explore their latest research and its impact on people’s health, healthcare, and health policy. A monthly audio companion to the journal, this podcast covers a broad range of topics, from early-stage breast cancer treatment to mRNA vaccines, the access to essential cancer medicines for children to measuring ovarian toxicity, and more.

The possibility of life elsewhere in the cosmos is one of the most profound subjects that human beings can ponder. Astrophysicist Andrew May gives an expert overview of our current state of knowledge, looking at how life started on Earth, the tell-tale ‘signatures’ it produces and how such signatures might be detected elsewhere in the solar system or on the many ‘exoplanets’ now being discovered by the Kepler and TESS missions.

What happens in our brains to make us feel fear, love, hate, anger, joy? Do we control our emotions, or do they control us? Do animals have emotions? How can traumatic experiences in early childhood influence adult behavior, even though we have no conscious memory of them? In The Emotional Brain, Joseph LeDoux investigates the origins of human emotions and explains that many exist as part of complex neural systems that evolved to enable us to survive.

The conscious mind, the part of your mental life you experience directly, is responsible for only a tiny sliver of what science says is going on inside your brain. Most of what you experience, your moods, and the things you like or dislike—most of who you are—comes from a much more mysterious part of your mind: the unconscious. And to really understand the influences of the unconscious, says psychiatrist Daniel Z. Liberman, coauthor of The Molecule of More, we need to look to something often considered science’s alter ego: magic.

Colin Wilson was one of the most prolific and eclectic writers of the 20th century. In more than 150 books and countless articles and contributions to other works, published over 50 years, he covered subjects as diverse as existentialism, esotericism and the occult, religion, biography, and several volumes of autobiography. 

From award-winning writer Leila Philip, BEAVERLAND is a masterful work of narrative science writing, a book that highlights, though history and contemporary storytelling, how this weird rodent plays an oversized role in American history and its future. She follows fur trappers who lead her through waist high water, fur traders and fur auctioneers, as well as wildlife managers, PETA activists, Native American environmental vigilantes, scientists, engineers, and the colorful group of activists known as beaver believers.

Birding can be an acoustic experience as much as a visual one. Songs and Sounds follows birding guide and nature recordist Rob Porter through various songbird and waterfowl habitats around southern Ontario during the course of a year. Recorded entirely outdoors in both natural and manmade habitats, this audiobook is like any other: you won't just hear about the birds; you will hear from the birds themselves during breeding season, migration, and wintering.

One of our greatest philosophers and scientists of the mind asks where the self comes from - and how our selves can exist in the minds of others. I Am a Strange Loop argues that the key to understanding selves and consciousness is the "strange loop" - a special kind of abstract feedback loop inhabiting our brains. The most central and complex symbol in your brain is the one called "I". The "I" is the nexus in our brain, one of many symbols seeming to have free will and to have gained the paradoxical ability to push particles around, rather than the reverse.

In this illuminating book, brain scientist and horsewoman Janet Jones describes human and equine brains working together. Using plain language, she explores the differences and similarities between equine and human ways of negotiating the world. Mental abilities—like seeing, learning, fearing, trusting, and focusing—are discussed from both human and horse perspectives. Throughout, true stories of horses and handlers attempting to understand each other—sometimes successfully, sometimes not—help to illustrate the principles.
