'A hugely useful and fascinating resume of rewilding - what it means, where it came from, why it's important and where it's going. Jepson and Blythe have done a masterly job, explaining the science behind rewilding in an accessible, honest and compelling way. It deserves to be widely read and become a book of great influence.' Isabella Tree, author of Wilding 'Compelling ... [a] succinct and objective account' Financial TimesRewilding is the first popular book on the ground-breaking science behind the restoration of wild nature.As ecologists Paul Jepson and Cain Blythe show, rewilding is a new and progressive approach to conservation, blending radical scientific insights with practical innovations to revive ecological processes, benefiting people as well as nature. Its goal is to restore lost interactions between animals, plants and natural disturbance that are the essence of thriving ecosystems.With its sense of hope and purpose, rewilding is breathing new life into the conservation movement, and enabling a growing number of people - even urban-dwellers - to enjoy thrilling wildlife experiences previously accessible only in remote wilderness reserves. 'De-domesticated' horses galloping across a Dutch 'Serengeti'; beavers creating wetlands in the British countryside; giant tortoises restoring the wildlife of the Mauritian islands; perhaps one day even rhinos roaming the Australian outback - rewilding is full of exciting and inspirational possibilities.

The ultimate non-technical guide to the fast-developing world of quantum computing Computer technology has improved exponentially over the last 50 years. But the headroom for bigger and better electronic solutions is running out. Our best hope is to engage the power of quantum physics. 'Quantum algorithms' had already been written long before hardware was built. These would enable, for example, a quantum computer to exponentially speed up an information search, or to crack the mathematical trick behind internet security. However, making a quantum computer is incredibly difficult. Despite hundreds of laboratories around the world working on them, we are only just seeing them come close to 'supremacy' where they can outperform a traditional computer. In this approachable introduction, Brian Clegg explains algorithms and their quantum counterparts, explores the physical building blocks and quantum weirdness necessary to make a quantum computer, and uncovers the capabilities of the current generation of machines.

Mars is back. Suddenly everyone - from Elon Musk to Ridley Scott to Donald Trump - is talking about going to the Red Planet.When the Apollo astronauts walked on the Moon in 1969, many people imagined Mars would be next. However NASA's Viking 1, which landed in 1976, was just a robot. The much-anticipated crewed mission failed to materialise, defeated by a combination of technological and political challenges.Four decades after Viking and almost half a century after Apollo technology has improved beyond recognition - as has politics. As private ventures like SpaceX seize centre stage from NASA, Mars has undergone a seismic shift - it's become the prime destination for future human expansion and colonisation.But what's it really like on Mars, and why should anyone want to go there? How do you get there and what are the risks? Astrophysicist and science writer Andrew May answers these questions and more, as he traces the history of our fascination with the Red Planet.

'Clear and compact ... It's hard to fault as a brief, easily digestible introduction to some of the biggest questions in the Universe' Giles Sparrow, BBC Four's The Sky at Night, Best astronomy and space books of 2019: 5/5All the matter and light we can see in the universe makes up a trivial 5 per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced.Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That 'something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence.Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

Is the Brexit vote successful big data politics or the end of democracy? Why do airlines overbook, and why do banks get it wrong so often? How does big data enable Netflix to forecast a hit, CERN to find the Higgs boson and medics to discover if red wine really is good for you? And how are companies using big data to benefit from smart meters, use advertising that spies on you and develop the gig economy, where workers are managed by the whim of an algorithm?The volumes of data we now access can give unparalleled abilities to make predictions, respond to customer demand and solve problems. But Big Brother's shadow hovers over it. Though big data can set us free and enhance our lives, it has the potential to create an underclass and a totalitarian state. With big data ever-present, you can't afford to ignore it. Acclaimed science writer Brian Clegg - a habitual early adopter of new technology (and the owner of the second-ever copy of Windows in the UK) - brings big data to life.

On 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed for ever.Until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays and the rest. But gravitational waves - ripples in the fabric of space and time - are unrelenting, passing through barriers that stop light dead.At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering.This was the first time black holes had ever been directly detected - and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.

Extraterrestrial life is a common theme inscience fiction, but is it a serious prospect in the real world? Astrobiologyis the emerging field of science that seeks to answer this question.The possibility of life elsewhere in the cosmosis one of the most profound subjects that human beings can ponder. AstrophysicistAndrew May gives an expert overview of our current state of knowledge, lookingat how life started on Earth, the tell-tale 'signatures' it produces, and howsuch signatures might be detected elsewhere in the Solar System or on the many 'exoplanets'now being discovered by the Kepler and TESS missions.Along the way the book addresses key questions such as the riddle of Fermi'sparadox ('Where is everybody?') and the crucial role of DNA and water - they'reessential to 'life as we know it', but is the same true of alien life? And the reallybig question: when we eventually find extraterrestrials, will they be friendlyor hostile?

In 2003, Russian physicists Andre Geim and Konstantin Novoselov found a way to produce graphene - the thinnest substance in the world - by using sticky tape to separate an atom-thick layer from a block of graphite.Their efforts would win the 2010 Nobel Prize for Physics, and now the applications of graphene and other 'two-dimensional' substances form a worldwide industry. Graphene is far stronger than steel, a far better conductor than any metal, and able to act as a molecular sieve to purify water. Electronic components made from graphene are a fraction of the size of silicon microchips and can be both flexible and transparent, making it possible to build electronics into clothing, produce solar cells to fit any surface, or even create invisible temporary tattoos that monitor your health.Ultra-thin materials give us the next big step forward since the transistor revolutionised electronics. Get ready for the graphene revolution.

The Higgs boson is the rock star of fundamental particles, catapulting CERN, the laboratory where it was found, into the global spotlight. But what is it, why does it matter, and what exactly is CERN? In the late 1940s, a handful of visionaries were working to steer Europe towards a more peaceful future through science, and CERN, the European particle physics laboratory, was duly born. James Gillies tells the gripping story of particle physics, from the original atomists of ancient Greece, through the people who made the crucial breakthroughs, to CERN itself, one of the most ambitious scientific undertakings of our time, and its eventual confirmation of the Higgs boson. Weaving together the scientific and political stories of CERN's development, the book reveals how particle physics has evolved from being the realm of solitary genius to a global field of human endeavour, with CERN's Large Hadron Collider as its frontier research tool.

Artificial intelligence has long been a mainstay of science fiction and increasingly it feels as if AI is entering our everyday lives, with technology like Apple's Siri now prominent, and self-driving cars almost upon us.But what do we actually mean when we talk about 'AI'? Are the sentient machines of 2001 or The Matrix a real possibility or will real-world artificial intelligence look and feel very different? What has it done for us so far? And what technologies could it yield in the future?AI expert Yorick Wilks takes a journey through the history of artificial intelligence up to the present day, examining its origins, controversies and achievements, as well as looking into just how it works. He also considers the future, assessing whether these technologies could menace our way of life, but also how we are all likely to benefit from AI applications in the years to come.Entertaining, enlightening, and keenly argued, this is the essential one-stop guide to the AI debate.

'A book that couldn't be more timely, providing an accessible introduction to epidemiology.' KirkusA compelling and disquieting journey through the history and science of epidemics.For centuries mankind has waged war against the infections that, left untreated, would have the power to wipe out communities, or even entire populations. Yet for all our advanced scientific knowledge, only one human disease - smallpox - has ever been eradicated globally.In recent years, outbreaks of Ebola and Zika have provided vivid examples of how difficult it is to contain an infection once it strikes, and the panic that a rapidly spreading epidemic can ignite. But while we chase the diseases we are already aware of, new ones are constantly emerging, like the coronavirus that spread across the world in 2020. At the same time, antimicrobial resistance is harnessing infections that we once knew how to control, enabling them to thrive once more.Meera Senthilingam presents a timely look at humanity's ongoing battle against infection, examining the successes and failures of the past, along with how we are confronting the challenges of today, and our chances of eradicating disease in the future.

'An excellent, brisk guide to what is likely to happen as opposed to the fantastically remote.' - Los Angeles Review of BooksIn 2018 the world woke up to gene editing with a storm of controversy over twin girls born in China with genetic changes deliberately introduced by scientists - changes they will pass on to their own offspring. Genetic modification (GM) has been with us for 45 years now, but the new system known as CRISPR or gene editing can manipulate the genes of almost any organism with a degree of precision, ease and speed that we could only dream of ten years ago. But is it ethical to change the genetic material of organisms in a way that might be passed on to future generations? If a person is suffering from a lethal genetic disease, is it unethical to deny them this option? Who controls the application of this technology, when it makes 'biohacking' - perhaps of one's own genome - a real possibility?Nessa Carey's book is a thrilling and timely snapshot of a cutting-edge technology that will radically alter our futures and the way we prevent disease.'A focused snapshot of a brave new world.' - Nature 'A brisk, accessible primer on the fast-moving field, a clear-eyed look at a technology that is already driving major scientific advances - and raising complex ethical questions.' - Emily Anthes, Undark

The quest to find a theory of quantum gravity that could potentially explain everything.Nearly 60 years ago, Nobel Prize-winners Arno Penzias and Robert Wilson stumbled across a mysterious hiss of faint radio static that was interfering with their observations. They had found the key to unravelling the story of the Big Bang and the origin of our universe.That signal was the Cosmic Microwave Background (CMB), the earliest light in the universe, released 379,000 years after the Big Bang. It contains secrets about what happened during the very first tiny increments of time, which had consequences that have rippled throughout cosmic history, leading to the universe of stars and galaxies that we live in today. This is the enthralling story of the quest to understand the CMB radiation and what it can tell us of the origins of time and space, from bubble universes to a cyclical cosmos - and possibly leading to the elusive theory of quantum gravity itself.

The controversial science that claims to have revolutionised economics.For centuries, economics was dominated by the idea that we are rational individuals who optimise our own 'utility'. Then, in the 1970s, psychologists demonstrated that the reality is a lot messier. We don't really know what our utility is, and we care about people other than ourselves. We are susceptible to external nudges. And far from being perfectly rational we are prone to 'cognitive biases' with complex effects on decision-making, such as forgetting to prepare for retirement. David Orrell explores the findings from psychology and neuroscience that are shaking up economics - and that are being exploited by policy-makers and marketers alike, to shape everything from how we shop for food, to how we tackle societal happiness or climate change. Finally, he asks: is behavioural economics a scientific revolution, or just a scientific form of marketing?

Dreams, schemes and opportunity as space opens for tourism and commerce.Twentieth century space exploration may have belonged to state-funded giants such as NASA, but there is a parallel history which has set the template for the future.Even before Apollo 11 landed on the Moon, private companies were exploiting space via communication satellites - a sector that is seeing exponential growth in the internet age. In human spaceflight, too, commercialisation is making itself felt. Billionaire entrepreneurs Elon Musk, Jeff Bezos and Richard Branson have long trumpeted plans to make space travel a possibility for ordinary people and those ideas are inching ever closer to reality. At the same time, other companies plan to mine the Moon for helium-3, or asteroids for precious metals.Science writer Andrew May takes an entertaining, in-depth look at the triumphs and heroic failures of our quixotic quest to commercialise the final frontier.

An exploration of the transformative ways in which nature has inspired the technological advancement of humankind.Biomimetics literally means emulating biology - and in a broader sense the term covers technological advances where the original inspiration came from nature. The Earth is a vast laboratory where the mechanisms of natural selection have enabled evolutionary solutions to be developed to a wide range of problems.In this new title in the Hot Science series, science writer Brian Clegg looks at how humans have piggybacked on natural experimentation, redeploying a solution to create things that make our lives easier. He looks at how the hooks on burdock seeds inspired the creation of Velcro, how the stickiness of the feet of geckos and frogs has been used to create gripping surfaces, such as tyre treads, and how even the most basic optical enhancement in the form of spectacles is itself a form of biomimetics.

Music is shaped by the science of sound.How can music - an artform - have anything to do with science? Yet there are myriad ways in which the two are intertwined, from the basics of music theory and the design of instruments to hi-fi systems and how the brain processes music.Science writer Andrew May traces the surprising connections between science and music, from the theory of sound waves to the way musicians use mathematical algorithms to create music.The most obvious impact of science on music can be seen in the way electronic technology has revolutionised how we create, record and listen to music. Technology has also provided new insights into the effects that different music has on the brain, to the extent that some algorithms can now predict our reactions with uncanny accuracy, which raises a worrying question: how long will it be before AI can create music on a par with humans?
