Trouet, a leading tree-ring scientist, takes us out into the field, from remote African villages to radioactive Russian forests, offering listeners an insider's look at tree-ring research, a discipline formally known as dendrochronology. Tracing her own professional journey while exploring dendrochronology's history and applications, Trouet describes the basics of how tell-tale tree cores are collected and dated with ring-by-ring precision, explaining the unexpected and momentous insights we've gained from the resulting samples.

Through riveting personal stories and the latest research, Harvard evolutionary biologist Carole Hooven shows how testosterone drives the behaviour of the sexes apart and how understanding the science behind this hormone is empowering for all.

At every moment, within your body and all around you, trillions of microscopic combatants are fighting an invisible war. Countless times per second, 'good' viruses known as phages are infecting and destroying bacteria. These phages are the most abundant life form on the planet and have an incredible power to heal rather than harm. So why have most of us never even heard of them? The Good Virus reveals how personalities, power and politics have repeatedly crashed together to hinder our understanding of these weird and wonderful life forms.

What defines who we are? For decades, the biological answer has been our genes. In The Master Builder, leading biologist Alfonso Martinez Arias breaks with decades of scientific and popular tradition to make a bold argument: what defines us is our cells. Drawing on new research from his lab and others, Martinez Arias reveals that we are composed of a thrillingly complex, constantly rearranging symphony of cells that know how to count, feel, and ultimately give form to our bodies.

James D. Watson, the Nobel laureate whose pioneering work helped unlock the mystery of DNA's structure, charts the greatest scientific journey of our time, from the discovery of the double helix to today's controversies to what the future may hold. Updated to include new findings in gene editing, epigenetics, and agricultural chemistry as well as two entirely new chapters on personal genomics and cancer research. This is the most comprehensive and authoritative exploration of DNA's impact on our society and our world.

Humans have kept honey bees in hives for millennia, yet only in recent decades have biologists begun to investigate how these industrious insects live in the wild. The Lives of Bees is Thomas Seeley’s captivating story of what scientists are learning about the behavior, social life, and survival strategies of honey bees living outside the beekeeper’s hive - and how wild honey bees may hold the key to reversing the alarming die-off of the planet’s managed honey bee populations.

Now in audio - a fascinating work of popular science from a world-renowned expert on mosquitoes and a prize-winning reporter. In this lively and comprehensive portrait of the mosquito, its role in history, and its threat to mankind, Spielman and D'Antonio take a mosquito's-eye view of nature and man. They show us how mosquitoes breed, live, mate, and die and introduce us to their enemies, both natural and man-made.

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?

Imagine a ferocious marine hunter up to 20 metres long, weighing twice as much as a humpback whale and ten times more than Tyrannosaurus rex. With jaws that open three metres wide, crammed with 276 serrated fangs, it can bite down with the greatest force of any animal that has ever lived. This is the Megalodon, and it once existed 3 million years ago. Acclaimed conservationist, palaeontologist and explorer Tim Flannery and his scientist daughter Emma tell the story of this enthralling great shark for the first time - what we know about where and how it lived, bred, hunted and died.

In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed - a toxic plant named for the sticky white substance emitted when its leaves are damaged - and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.

Menstruation is something half the world does for a week at a time, for months and years on end, yet it remains largely misunderstood. Scientists once thought of an individual’s period as useless and some doctors still believe it’s unsafe for a menstruating person to swim in the ocean wearing a tampon. Period counters the false theories that have long defined the study of the uterus, exposing the eugenic history of gynecology while providing an intersectional feminist perspective on menstruation science.

The Revolutionary Phenotype is a science book that brings us four billion years into the past, when the first living molecules showed up on Planet Earth. Unlike what was previously thought, we learn that DNA-based life did not emerge from random events in a primordial soup. Indeed, the first molecules of DNA were fabricated by a previous life form.

In this lively, lucid book, science writer David Stipp ponders Darwinian puzzles about nine familiar creatures and things—bumblebees, dogs, sparrows, caffeine, earthworms, and sleep, among others—to show how rewarding it can be to look at nature in this deeper way. By revealing hidden depths of the ordinary, The Everyday Darwinist shows not only that fascinating intricacies lie just beneath the natural world's familiar surfaces, but also that noticing them lets us connect dots that in many cases we didn't realize existed. This is backyard biophilia at its most entertaining and enlightening.

Several years ago, ecologist Lauren E. Oakes set out from California for Alaska's old-growth forests to hunt for a dying tree: the yellow-cedar. With climate change as the culprit, the death of this species meant loss for many Alaskans. Oakes and her research team wanted to chronicle how plants and people could cope with their rapidly changing world. Amidst the standing dead, she discovered the resiliency of forgotten forests, flourishing again in the wake of destruction, and a diverse community of people who persevered to create new relationships with the emerging environment.

Ignác Semmelweis is remembered for the now-commonplace notion that doctors must wash their hands before examining patients. In mid-19th century Vienna, however, this was a subversive idea. With deaths from childbed fever exploding, Semmelweis discovered that doctors themselves were spreading the disease. While his simple reforms worked immediately - childbed fever in Vienna all but disappeared - they brought down upon Semmelweis the wrath of the establishment, and led to his tragic end.

At the age of 16, renowned Australian palaeontologist Tim Flannery made a discovery that would spark a lifelong passion. Along the bank of a creek in his home state of Victoria, he found the fossilised tooth of a megalodon, a giant shark that roamed our oceans millions of years ago. This remarkable find, the tooth was large enough to cover his palm, sparked an interest in palaeontology that was to inform his life’s work and a lifelong quest to uncover the secrets of the world’s largest ever predator, the great shark Otodus megalodon.
