How Much Brain Do We Really Need? challenges you to think differently about the brain. Rather than solely concentrating on the many wonderful things the brain can do, it asks whether in fact we can live satisfactorily without some of it. It turns out that brain shrinkage, for instance, is no rare thing. While the bad news for all of us is that from our mid-30s our brains start to shrink, the good news is that somehow we generally still seem to muddle along. But how can this be?

As the BBC's North America Editor, Jon Sopel has had a pretty busy time of it lately. In the 18 months it's taken for a reality star to go from laughingstock to leader of the free world, Jon has travelled the length and breadth of the United States, experiencing it from a perspective that most of us could only dream of: he has flown aboard Air Force One, interviewed President Obama and has even been described as 'a beauty' by none other than Donald Trump.

Mars, the red planet, is ingrained in our culture, from David Bowie's extra-terrestrial spiders to Captain Scarlet to War of the Worlds. It has inspired hundreds of authors, scientists and science-fiction writers - but why? What is it about this particular planet that makes it so intriguing? Ancient mythologies defined Mars as a violent harbinger of war, star-gazers puzzled over its peculiar motion, and astrologers defined human personalities by its position and bizarre dance through the sky.

Pig/Pork explores the love-hate relationship between humans and pigs through the lenses of archaeology, biology, history and gastronomy, providing a close and affectionate look at the myriad causes underlying this multimillennial bond. What is it that people in all four corners of the world find so fascinating about the pig? When did the human obsession with pigs begin, how did it develop through time and where is it heading? Why are pigs so special to some of us but not to others?

We depend on - we believe in - algorithms to help us get a ride, choose which book to buy, execute a mathematical proof. It's as if we think of code as a magic spell, an incantation to reveal what we need to know and even what we want. Humans have always believed that certain invocations - the marriage vow, the shaman's curse - do not merely describe the world but make it.

Worm: The First Digital World War tells the story of the Conficker worm, a potentially devastating piece of malware that has baffled experts and infected more than twelve million computers worldwide. When Conficker was unleashed in November 2008, cybersecurity experts did not know what to make of it. Exploiting security flaws in Microsoft Windows, it grew at an astonishingly rapid rate, infecting millions of computers around the world within weeks.

What is transhumanism? Simply put, it is a movement whose aim is to use technology to fundamentally change the human condition, to improve our bodies and minds to the point where we become something other, and better, than the animals we are. It's a philosophy that, depending on how you look at it, can seem hopeful, or terrifying, or absurd. In To Be a Machine, Mark O'Connell presents us with the first full-length exploration of transhumanism.

The word "barbarian" quickly conjures images of Attila the Hun and Genghis Khan. Yet few people realize these men belong to a succession of nomadic warriors who emerged from the Eurasian steppes to conquer civilizations. It's a part of ancient and medieval history that's often overlooked, but for an accurate view of how the world evolved, it's essential. Covering some 6,000 miles and 6,000 years, this eye-opening course illuminates how a series of groups pushed ever westward, coming into contact with the Roman Empire, Han China, and distant cultures from Iraq to India.

Imagine a world without bees, butterflies, and flowering plants. That was Earth 125 million years ago. Turn back the clock 400 million years, and there were no trees. At 450 million years in the past, even the earliest insects had not yet developed. And looking back 500 million years, the land was devoid of life, which at that time flourished in a profusion of strange forms in the oceans. These and other major turning points are the amazing story of evolution.

The field of mind-body medicine is plagued by wild claims that mislead patients and instil false hope. But as scientists in a range of fields uncover solid evidence that our minds influence our bodies quite profoundly, there is now great promise, too. Jo Marchant attempts to use scientific research to find out if alternative medicines work; if our thoughts, beliefs and emotions influence our physical health; and if we can train our brains to heal our bodies.

'I have a truly marvellous demonstration of this proposition which this margin is too narrow to contain.' It was with these words, written in the 1630s, that Pierre de Fermat intrigued and infuriated the mathematics community. For over 350 years, proving Fermat's Last Theorem was the most notorious unsolved mathematical problem, a puzzle whose basics most children could grasp but whose solution eluded the greatest minds in the world.

Over 5,000 years, India has been home to a rich tapestry of peoples and cultures. Two of the world's great religions - Hinduism and Buddhism - have their origins in South Asia, and the lands east of the Indus River have long been a central hub for trade, migration, and cultural exchange. Today the subcontinent contains 20 percent of the world's population and is a thriving center for global business, making this region one of most significant economic powerhouses in the world.

Maybe it was a viral pandemic or an asteroid strike or perhaps nuclear war. Whatever the cause, the world as we know it has ended, and you and the other survivors must start again. What key knowledge would you need to start rebuilding civilisation from scratch? Once you’ve scavenged what you can, how do you begin producing the essentials? How do you grow food, generate power, prepare medicines, or get metal out of rocks? Could you avert another Dark Ages or take shortcuts to accelerate redevelopment?

Penguin presents the audiobook edition of The Mind Is Flat, written and read by Nick Chater. Most of us assume that our thoughts, desires and behaviour arise from the murky depths of our minds, and if only we could access this inner world we could truly understand ourselves. For more than a century, psychologists, psychiatrists and neuroscientists have struggled, using methods from psychotherapy to brain scans, to discover what lies below the surface of our minds. In a profound reappraisal of how the mind works, preeminent behavioural scientist Nick Chater reveals that this entire enterprise is misguided: that we have no mental depths to plumb.

How did we get here? All cultures have a creation story, but a little over 150 years ago, Charles Darwin introduced a revolutionary new one. We, and all living things, exist because of the action of evolution on the first simple life form and its descendants. In How Evolution Explains Everything About Life, leading biologists and New Scientist take you on a journey of a lifetime, exploring the questions of whether life is inevitable or a one-off fluke and how it got kick-started.
