What is life? Humans have been asking this question for thousands of years. But as technology has advanced and our understanding of biology has deepened, the answer has evolved. For decades, scientists have been exploring the limits of nature by modifying and manipulating DNA, cells, and whole organisms to create new ones that could never have previously existed on their own.

Most of us think that longevity hinges on maintaining a normal Body Mass Index. But research conducted over the last decade hit the media in January with explosive news: Overweight and even moderately obese people with certain chronic diseases - from heart disease to cancer - often live longer and fare better than normal-weight individuals with the same ailments. In this groundbreaking audiobook, Carl Lavie, MD, reveals the science behind the obesity paradox and shows us how to achieve maximum health rather than minimum weight.

Today, we know more about mental health than ever before, but traditional medicine still mistakes subtle signs of trauma for stress, anxiety, or chronic disease—sometimes even retraumatizing patients with outdated and misguided methods. Treatment plans that focus on the mind are only addressing the downstream effects. Likewise, common medical approaches to manage symptoms fail to explore root causes and promote genuine recovery.

In all animals, mating is a deal. But few creatures behave as if sex is a simple, even mutually beneficial, transaction. Many more treat it with reverence, suspicion, angst, and violence. In the case of the Black Grouse, the bird at the center of Matt Ridley’s investigation, the males dance and sing for hours a day, for several exhausting months, in an arduous and even deadly ritual called a “lek.” To prepare for the ordeal, they grow, preen and display fancy, twisted, bold-colored feathers. When achieved, consummation with a female takes seconds.

Geoffrey West's research centres on a quest to find unifying principles and patterns connecting everything, from cells and ecosystems to cities, social networks and businesses. Scale addresses big, urgent questions about global sustainability, population explosion, urbanization, ageing, cancer, human life spans and the increasing pace of life but also encourages us to question the world around us.

A natural history of the wilderness in our homes, from the microbes in our showers to the crickets in our basements Even when the floors are sparkling clean and the house seems silent, our domestic domain is wild beyond imagination. In Never Home Alone, biologist Rob Dunn introduces us to the nearly 200,000 species living with us in our own homes, from the Egyptian meal moths in our cupboards and camel crickets in our basements to the lactobacillus lounging on our kitchen counters. You are not alone.

We all remember the "P" word we dreaded hearing about as adolescents...puberty. Sweaty, sticky, and pimply, we all go through puberty at some point in our lives, but why? Listen in as Seeker takes you on a scientific roller coaster ride of all things puberty like acne, hormones, body odor and more in this curated audio collection.

The knowledge of death is so terrifying that we live most of our lives in denial of it. Our fear of death has underpinned our religions, inspired our cultures, and also driven our science. Today we are living through a revolution in biology. Giant strides are being made in our understanding of why we age and die, and why some species live longer than others. Immortality, once a faint hope, has never been more within our grasp. Here, Nobel Prize-winning biologist Venki Ramakrishnan offers a definitive look at why we die - and whether we can do anything about it.

This is an inspiring tour of the world's oceans and 80 of its most notable inhabitants. Beautifully illustrated, the book includes fascinating stories of the fish, shellfish and other sea life that have somehow impacted human life - whether in our medicine, culture or folklore - in often surprising and unexpected ways.

In the late 1600s, a distinguished English polymath, Robert Hooke, and an eccentric Dutch cloth-merchant, Antonie van Leeuwenhoek, look down their hand-made microscopes. What they see introduces a radical concept that sweeps through biology and medicine, touching virtually every aspect of the two sciences and altering both forever. It is the fact that complex living organisms are assemblages of tiny self-contained, self-regulating units. Our organs, our physiology, our selves—hearts, blood, brains—are built from these compartments. Hooke christens them "cells".

Locked in the silence and darkness of your skull, your brain fashions the rich narratives of your reality and your identity. Join renowned neuroscientist David Eagleman for a journey into the questions at the mysterious heart of our existence. What is reality? Who are “you”? How do you make decisions? Why does your brain need other people? How is technology poised to change what it means to be human?

The key to living a happier, healthier life is inside us. Our gut is almost as important to us as our brain or our heart, yet we know very little about how it works. In Gut, Giulia Enders shows that rather than the utilitarian and - let's be honest - somewhat embarrassing body part we imagine it to be, it is one of the most complex, important, and even miraculous parts of our anatomy.

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.

Ants number in the ten quadrillions, and they have been here since the Jurassic era. Inside an anthill, you'll find high drama worthy of a royal court; and between colonies, high-stakes geopolitical intrigue is afoot. Just like us, ants grow crops, raise livestock, tend their young and infirm, and make vaccines. And, just like us, ants have a dark side: They wage war, despoil environments, and enslave rivals - but also rebel against their oppressors.

In this audiobook, Dr Kruszelnicki takes us on another exploration of the dazzling world of science. Does cranberry juice cure urinary tract infections? Is the hookah really a safer way to smoke? Will the Large Hadron Collider destroy the Earth and the Universe?

Our human brain is both unique and similar to that of other species. The only way we can trace its evolution is by comparing it to the brains of animals alive today. In this book, leading neuroscientist Rogier Mars offers an engaging account of the evolution of the brain by exploring the brains and cognitive capacities of animals from the humble sea squirt to the socially minded fox and the tiny shrew.

Enticingly read by the author, Philip Ball. 'An essential primer on humanity’s ongoing quest to understand the secrets of life . . . Excellent . . . Ball is a terrific writer.' – Adam Rutherford, The Guardian A cutting-edge new vision of biology that proposes to revise our concept of what...

In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy.

It seems like every time a new mother turns on her computer, radio, or television she is greeted with news of yet another scientific study about infancy. Ignoring good information isn't the right course, but just how does one tell the difference between solid studies, preliminary results, and snake oil? In this friendly guide through the science of infancy, Science of Mom blogger and PhD scientist Alice Callahan explains how nonscientist mothers can learn the difference between hype and evidence.

The emergence of strange new diseases is a frightening problem that seems to be getting worse. In this age of speedy travel, it threatens a worldwide pandemic. We hear news reports of Ebola, SARS, AIDS, and something called Hendra killing horses and people in Australia - but those reports miss the big truth that such phenomena are part of a single pattern. The bugs that transmit these diseases share one thing: they originate in wild animals and pass to humans by a process called spillover. David Quammen tracks this subject around the world.
