Locked away, remote from the rest of the body in its own custom-built casing of skull bone, with no intrinsic moving parts, the human brain remains a tantalising mystery. But now, more than ever before, we have the expertise to tackle this mystery - the last 20 years have seen astounding progress in brain research. Susan Greenfield begins by exploring the roles of different regions of the brain.

Early birds and night owls are born, not made. Sleep patterns are the most obvious manifestation of the highly individualized biological clocks we inherit, but these clocks also regulate bodily functions from digestion to hormone levels to cognition. By understanding and respecting our internal time, we can live better.

We inherit mechanisms for survival from our primeval past - none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: It changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world.

Improbable Destinies will change the way we think and talk about evolution. Losos' insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet - having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and created breathtaking works of art - while chimps remain animals concerned primarily with the basic necessities of survival. What is it about that two percent difference in DNA that has created such a divergence between evolutionary cousins?

Finally, answers to all those strange questions you'd like to ask your own doctor but haven't had the guts (or more likely the time) to do so.

<>The Stokes Field Guide to Bird Songs: Eastern Region offers you the very best sound recordings available for the birds of eastern North America. It includes more species, more time per species, and more sounds per species than any other audio guide to Eastern bird songs. In addition, the recordings are accompanied by an informative pdf booklet that gives precise call and song descriptions of the 372 species included.

Physik war lange das meistgehasste Fach in der Schule, und Physiker galten nicht gerade als besonders sexy...

Why do people believe bunk? And what causes them to embrace such pseudoscientific beliefs and practices? Noted skeptic Massimo Pigliucci sets out to separate the fact from the fantasy in this entertaining exploration of the nature of science, the borderlands of fringe science, and - borrowing a famous phrase from philosopher Jeremy Bentham - the nonsense on stilts.

In Extreme, Emma Barrett and Paul Martin explore the challenges that people in extreme environments face, including pain, physical hardship, loneliness, and friction between individuals, and the approaches taken to overcome them. Using many fascinating examples and personal accounts, they argue that we can all benefit from the insights gained.

Thousands of people just like you have been raising bees and making their own honey right in their own backyards. Learn the ins and outs of the joy of keeping bees in this information packed beekeeping 101 guide.

If you have a taste for honey or an adventurous side, maybe you have thought of becoming a beekeeper. What would you really be in for, though? Is it really a job, or is it a fun way to get your own honey? Well, it's really both. Being a beekeeper is a lot of work, but it also has a lot of benefits. Anyone can do it, as long as they know to be prepared. You can't just wake up one day and decided to be a beekeeper and start immediately, without knowing what you are doing.

Can twins have different fathers? From the composition and function of human sex organs to the fascinating biochemistry behind sexual attraction, How Sex Works presents captivating new ideas and surprising answers to questions about contraception, fertility, circumcision, menopause, STDs, homosexuality, orgasms, and more. This is an entertaining, comprehensive exploration of culture, biology, and history that takes us far beyond our common understanding of sex.

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

An award-winning scientist offers a groundbreaking new understanding of the mind-body connection and its profound impact on everything from advertising to romance. The human body is not just a passive device carrying out messages sent by the brain but rather an integral part of how we think and make decisions.

Dolphins have fascinated humans for millennia, giving rise to an abundance of stories and myths about them, yet the actual details of their lives in the sea have remained elusive. In this enthralling book, Kathleen M. Dudzinski and Toni Frohoff take us into the dolphins' aquatic world to witness firsthand how they live their lives, communicate, and interact with one another and with other species, including people.

Your body is teeming with tens of trillions of microbes. It's an entire world, a colony full of life. In other words, you contain multitudes. These microscopic companions sculpt our organs, protect us from diseases, guide our behaviour and bombard us with their genes. They also hold the key to understanding all life on earth. In I Contain Multitudes, Ed Yong opens our eyes and invites us to marvel at ourselves and other animals in a new light, less as individuals and more as thriving ecosystems.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

How does life work? How does nature produce the right numbers of zebras and lions on the African savanna, or fish in the ocean? How do our bodies produce the right numbers of cells in our organs and bloodstream? In The Serengeti Rules, award-winning biologist and author Sean B. Carroll tells the stories of the pioneering scientists who sought the answers to such simple yet profoundly important questions.

Entomologist Justin O. Schmidt is on a mission. Some say it's a brave exploration, others shake their heads in disbelief. His goal? To compare the impacts of stinging insects on humans, mainly using himself as the gauge. In The Sting of the Wild, the colorful Dr. Schmidt takes us on a journey inside the lives of stinging insects, seeing the world through their eyes as well as his own.
