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.

The Western Front, 1916. Private Percy Blakeney wakes up. He is lying on fresh spring grass. He can hear birdsong and the wind in the leaves.

Police officer Monica Jansson is exploring the burned-out home of a reclusive - some say mad, others allege dangerous - scientist who seems to have vanished. Sifting through the wreckage, Jansson find a curious gadget.

The world's largest land mammal could help us end cancer. The fastest bird is showing us how to solve a century-old engineering mystery. The oldest tree is giving us insights into climate change. The loudest whale is offering clues about the impact of solar storms. For a long time, scientists ignored superlative life forms as outliers. Increasingly, though, researchers are coming to see great value in studying plants and animals that exist on the outermost edges of the bell curve.

Centered in the Dordogne region of Southwestern France, one of Europe's most concentrated regions for Neandertal and early modern human occupations, writer Beebe Bahrami follows and participates in the work of archaeologists who are doing some of the most comprehensive and global work to date on the research, exploration, and recovery of our ancient ancestors. From this prehistoric perch, Bahrami gets to know firsthand the Neandertals and the people who love them.

It may be a wonderful world, but as Dan Riskin explains, it's also a dangerous, disturbing, and disgusting one. At every turn, it seems, living things are trying to eat us, poison us, use our bodies as their homes, or have us spread their eggs. In Mother Nature Is Trying to Kill You, Riskin is our guide through the natural world at its most gloriously ruthless. Using the seven deadly sins as a road map, Riskin offers dozens of jaw-dropping examples that illuminate how brutal nature can truly be.

Mary Roach meets Sam Kean and Bill Bryson in this uproarious tour of the basest instincts and biggest mysteries of the animal world. In The Truth About Animals, Lucy Cooke takes us on a worldwide journey to meet everyone from a Colombian hippo castrator to a Chinese panda porn peddler, all to lay bare the secret - and often hilarious - habits of the animal kingdom. Charming and at times downright weird, this modern bestiary is perfect for anyone who has ever suspected that virtue might be unnatural.

Geneticist Adam Rutherford and mathematician Hannah Fry guide listeners through time and space, through our bodies and brains, showing how emotions shape our view of reality, how our minds tell us lies, and why a mostly bald and curious ape decided to begin poking at the fabric of the universe.

Rosemary and Peter Grant and those assisting them have spend 20 years on Daphne Major, an island in the Galapagos, studying natural selection. They recognize each individual bird on the island, when there are 400 at the time of the author's visit or when there are over a thousand. They have observed about 20 generations of finches - continuously.Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself.

In The Lives of a Cell, Dr. Lewis Thomas opens up to the listener a universe of knowledge and perception that is perhaps not wholly unfamiliar to the research scientist; but the world he explores is also one of men and women, of complex interrelationships, old ironies, peculiar powers, and intricate languages that give identity to the alienated and direction to the dependent. This remarkable work offers a subtle, bold vision of humankind and the world around us - a sense of what gives life - from a writer who seems to draw grace and strength from the very substance of his subject.

How are eggs of different shapes made, and why are they the shapes they are? When does the shell of an egg harden? Why do some eggs contain two yolks? How are the colours and patterns of eggshells created, and why do they vary? And which end of an egg is laid first - the blunt end or the pointy end?

Feathers are an evolutionary marvel: Aerodynamic, insulating, beguiling. They date back more than 100 million years. Yet their story has never been fully told. In Feathers, biologist Thor Hanson details a sweeping natural history, as feathers have been used to fly, protect, attract, and adorn through time and place. Applying the research of paleontologists, ornithologists, biologists, engineers, and even art historians, Hanson asks: What are feathers? How did they evolve? What do they mean to us?
