Congratulations! You're the proud owner of the most complex information processing device in the known universe. The human brain comes equipped with all sorts of useful design features, but also many bugs and weaknesses. Problem is you don't get an owner's manual. You have to just plug and play. As a result, most of us never properly understand how our brains work and what they're truly capable of. We fail get the best out of them, ignore some of their most useful features and struggle to overcome their design faults.

The End of Money is an essential introduction to cryptocurrencies and the blockchain revolution, which has been hailed as the greatest advancement since the invention of the Internet. Murder for hire. Drug trafficking. Embezzlement. Money laundering. These might sound like plot lines of a thriller, but they are true stories from the short history of cryptocurrencies - digital currencies conceived by computer hackers and cryptographers that represent a completely new sort of financial transaction.

Are you tired of hearing about coronavirus? Has lockdown left you worn out? Then perhaps it’s time to escape. Join Rowan Hooper and the team at New Scientist in this covid-free space, as they discuss all that’s right with the world - the stories that remind us of how wonderful this planet really is.

The story of how our ancestors made the first tentative steps towards becoming human, how we lost our fur but gained language, fire and tools, and how we strode out of Africa, invented farming and cities and ultimately created modern civilisation. Where did we come from? Where are we going? Homo sapiens is the most successful, the most widespread and the most influential species ever to walk the Earth.

Think of a number between one and 10. No, hang on, let's make this interesting. Between zero and infinity. Even if you stick to the whole numbers, there are a lot to choose from - an infinite number in fact. Throw in decimal fractions, and infinity suddenly gets an awful lot bigger (is that even possible?). And then there are the negative numbers, the imaginary numbers, the irrational numbers like pi which never end. It literally never ends.

This Is Planet Earth is dedicated to the wonders of planet Earth, the most amazing place in the known universe. The ancient Greeks called it Gaia, the Romans Terra. We know it simply as Earth, the planet we call home. And what a planet it is. Formed around 4.6 billion years ago from the debris of the big bang and long-dead stars, at first it was nothing special, but somehow it evolved to become the most amazing place in the known universe.

A Journey Through the Universe is a grand tour of the most amazing celestial objects and how they fit together to build the cosmos. There's a whole universe out there.... Imagine you had a spacecraft capable of travelling through interstellar space. You climb in, blast into orbit, fly out of the solar system and keep going. Where do you end up, and what do you see along the way? The answer is: mostly nothing. Space is astonishingly, mind-blowingly empty.

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.

Machines That Think explores how artificial intelligence helps us understand human intelligence, machines that compose music and write stories - and asks if AI is really a threat. Sometime in the future, the intelligence of machines will exceed that of human brain power. So are we on the edge of an AI-pocalypse, with superintelligent devices superseding humanity, as predicted by Stephen Hawking? Or will this herald a kind of utopia, with machines doing a far better job at complex tasks than us?

As you read this, billions of neutrinos from the sun are passing through your body, antimatter is sprouting from your dinner and the core of your being is a chaotic mess of particles known only as quarks and gluons. If the recent discovery of the Higgs boson piqued your interest, then Why the Universe Exists will take you deeper into the world of particle physics, with leading physicists and New Scientist exploring how the universe functions at the smallest scales.

What is this strange mental world that seems so essential to being human? The conscious mind brings together sensations, perceptions, thoughts and memories to generate the seamless movie of a person's life. It makes us aware of the world around us and our own self. How all this emerges from a kilogram of brain cells is one of the greatest unanswered questions.

What is it that makes us human? Is it language, imagination, morality, or is it that we cook and wear shoes? Or perhaps we are less human than we think - Neanderthal and Denisovan genes can be found within all of us! Once again, New Scientist have all of the unexpected answers, and - just as they did for the universe in The Origin of (Almost) Everything - they take us on a tour around the human body and brain, taking in everything from evolution to email, from the Stone Age to Spotify.

A journey through life, the universe and everything. From what actually happened in the big bang to the accidental discovery of Post-it notes, science is packed with surprising discoveries. Did you know, for instance, that if you were to get too close to a black hole it would suck you up like a noodle (it's called spaghettification), why your keyboard is laid out in QWERTY (it's not to make it easier to type) or whether the invention of the wheel was less important to civilisation than the bag (think about it)? New Scientist does.

A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. His theory changed the way we think about space and time, revealed how our universe has been expanding from a hot, dense state called the big bang and predicted black holes. Where the Universe Came From is a 13.8 billiion-year journey through the cosmos.

In The Quantum World, leading physicists and New Scientist take you on a journey through quantum theory, its mind-bending properties and the technologies transforming our world. Forget everything you thought you knew about reality. The world is a seriously bizarre place. Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched.

In How Your Brain Works, leading neuroscientists and New Scientist introduce the evolution and anatomy of the brain viewed through traits such as memory, emotions, sleep, sensing and perception. Ever wondered what's going on inside your head? You are your brain. Everything that makes you you, and all your experiences of the world, are somehow conjured up by 1.4 kilograms of grey matter inside your skull.

What's the nature of reality? Does the universe ever end? What is time, and does it even exist? These are the biggest imagination-stretching, brain-staggering questions in the universe - and here are their fascinating answers. From quantum weirdness to freaky cosmology (like white holes - which spew out matter instead of sucking it in), This Book Will Blow Your Mind takes you on an epic journey to the furthest extremes of science, to the things you never thought possible.

From stress to saturated fats, HIIT to HRT, veganism to vitamins, This Book Could Save Your Life debunks the fads and explores the real science of better health. What's the best way to lose weight (and keep it off)? How can you ensure a good night's sleep? What are the real superfoods? Cutting through confusing statistics and terrifying headlines, here is the truth about dieting, drugs, 10,000 steps a day, bacon, calorie counting, coffee, dairy, sleep, fibre, hangovers, salt, sugar, cardio, sunscreen, statins, vitamins and much more.
