What does a mammoth smell like? Do dinosaurs bob their heads as they walk, like today’s birds? Do aurochs moo like cows? You may soon find out.

From the Siberian permafrost to balmy California, scientists across the globe are working to resurrect all kinds of extinct animals, from ones that just left us to those that have been gone for many thousands of years. Their tools in this hunt are both fossils and cutting-edge genetic technologies. Some of these scientists are driven by sheer curiosity; others view the lost species as a powerful weapon in the fight to save rapidly disappearing ecosystems.

Science journalist Torill Kornfeldt travelled the world to meet the men and women working to bring extinct animals back from the dead. Along the way, she saw a mammoth that has been frozen for 20,000 years, and visited the places where these furry giants once walked. It seems certain that they and other lost species will walk the earth again, but what world will that give us? And is any of this a good idea?

This book covers thirty years of the Leningrad Mathematical Olympiad, which was, ostensibly, the very first formally organized, open, official city-level mathematical contest in the world. Founded in 1934 by a group of dedicated Soviet mathematicians, it played an outstanding (and often underappreciated) role in creating the Leningrad (St. Petersburg) school of mathematics of the 20th century.The book begins with the extensive introduction containing two prefaces (one of them written specifically for this edition), a large historical survey of the Leningrad Mathematical Olympiad, a section describing the logistical side of the contest, and a small chapter dedicated to the very first Mathematical Olympiad held in 1934, whose problems were recently found in the Soviet-era library archives.The main text contains approximately 1,100 highly original questions for students of grades 5 through 10 (ages 11-12 through 17-18) offered at the two concluding rounds of the Leningrad City Mathematics Olympiads in the years of 1961-1991. Full solutions, hints and answers are provided for all questions with very rare exceptions.It also includes 120 additional questions, offered at the various mathematical contests held in Leningrad over the same thirty-year period — on average, their difficulty is somewhat higher than that of the regular Mathematical Olympiad problems.

Since the earliest humans walked the earth, the vast mysteries and wonders of the night sky have fascinated and beguiled us, as we’ve struggled to understand our place in the cosmos. Even after the last century, which saw important and startling discoveries about our own planet, our solar system and the stars and galaxies beyond, there remain more questions than answers. But those questions – What is dark matter? Are we alone in the universe? Is time travel possible? – provide a fascinating insight into the vastness and infinite possibilities of space that we’re yet to determine. The sheer scale of the universe can be intimidating, but in this easily digestible book we embark on an incredible journey through all the essential astronomical discoveries, from the beliefs of ancient civilizations, through to the recent groundbreaking observations of the gravitational waves predicted by Einstein over 100 years ago. There’s never been a better time to get to grips with the universe and this essential guide to the cosmos is the perfect place to start!

Never before have we had so much information available to us about food and health. There’s GAPS, paleo, detox, gluten-free, alkaline, the sugar conspiracy, clean eating... Unfortunately, a lot of it is not only wrong but actually harmful. So why do so many of us believe this bad science?

Assembling a crack team of psychiatrists, behavioural economists, food scientists and dietitians, the Angry Chef unravels the mystery of why sensible, intelligent people are so easily taken in by the latest food fads, making brief detours for an expletive-laden rant. At the end of it all you’ll have the tools to spot pseudoscience for yourself and the Angry Chef will be off for a nice cup of tea – and it will have two sugars in it, thank you very much.

Introducing the Collins Modern Classics, a series featuring some of the most significant books of recent times, books that shed light on the human experience - classics which will endure for generations to come. 'Maths is one of the purest forms of thought, and to outsiders mathematicians may seem almost otherworldly' In 1963, schoolboy Andrew Wiles stumbled across the world's greatest mathematical problem: Fermat's Last Theorem. Unsolved for over 300 years, he dreamed of cracking it. Combining thrilling storytelling with a fascinating history of scientific discovery, Simon Singh uncovers how an Englishman, after years of secret toil, finally solved mathematics' most challenging problem. Fermat's Last Theorem is remarkable story of human endeavour, obsession and intellectual brilliance, sealing its reputation as a classic of popular science writing. 'To read it is to realise that there is a world of beauty and intellectual challenge that is denied to 99.9 per cent of us who are not high-level mathematicians' The Times

A genuine understanding of how mental states arise from the structure and function of the brain would be, as William James declared in 1892, "the scientific achievement before which all past achievements would pale." Can a comprehensive biological theory of consciousness be constructed in 1990? Any attempt has to reconcile evidence garnered from such diverse fields as developmental and evolutionary biology, neuroanatomy and neurophysiology, cognitive psychology, psychiatry, and philosophy.Having laid the groundwork in his critically acclaimed books Neural Darwinism (Basic Books, 1987) and Topobiology (Basic Books, 1988), Nobel laureate Gerald M. Edelman now proposes a comprehensive theory of consciousness in The Remembered Present . Integrating findings generated by the recent explosive growth in the neurosciences with current knowledge of anatomy, cell biology, and psychology, Edelman has been able to construct a detailed model of how we become aware of our own existence.In addition to providing a scientific account of brain function and consciousness, the theory advanced in The Remembered Present will have a significant impact on a wide variety of fields. It provides a new outlook that may prompt fundamental revisions in the way linguists view language, physicians classify mental diseases, and philosophers look at the mind-body problem.

Molds are everywhere: we inhale their microscopic spores from birth to death. But when an investigation in Ohio revealed that babies suffering from a serious lung illness had been exposed to a toxic black mold in their homes, millions of Americans became nervous about patches of mold in their own basements and bathrooms. Before long, lawsuits were filed by the residents of mold-contaminated homes in every state. By failing to address water damage, building contractors, plumbers, and insurance agents were held liable for exposing families to an unprecedented microbiological hazard. The mold crisis soon developed into a fully-fledged media circus. In Carpet Monsters and Killer Spores, Nicholas Money explores the science behind the headlines and courtroom dramas, and profiles the toxin-producing mold that is a common inhabitant of water-damaged buildings. Nicholas Money tells the most important mycological story since potato blight, with his inimitable style of scientific clarity and dark humor.

Freeman Dyson's life experiences made him a wise, kindly grandfather figure to two generations of students enrolled in an undergraduate university course 'Science, Technology, & Society.' Near the end of each semester, the class sent him written questions, on reading Professor Dyson's memoir Disturbing the Universe. The letter exchanges occurred regularly from April 1993 through December 2019.'Yours Ever, Freeman' is devoted to this correspondence between Professor Dyson and the students. His responses went beyond answering questions, as he enlarged the scope of the questions by sharing stories from his experiences. While others have written of Professor Dyson's accomplishments and awards; the class came to know him through his discussions about life, science, and society. Topics ranged from the existential to headlines of the day, from national policies to personal values. Over three thousand students have been blessed to count Freeman Dyson as a mentor and consider him as a friend.'Yours Ever, Freeman' supplements Dear Professor Dyson published earlier. While the 2016 book included in-depth reviews of the STS course contents from which the correspondence emerged, besides including the 2016-2019 correspondence, the present book maintains a tight focus on the correspondence itself, annotated as necessary for context. The book's title comes from the way Professor Dyson signed his letters.

Why do most diets fail? Why does one person eat a certain meal and gain weight, while another eating the same meal loses pounds? Why, despite all the advice about what to eat, are we all still getting fatter?

The answers are much more surprising - and fascinating - than we've been led to believe. The key to health and weight loss lies not in the latest fad diet, nor even in the simple mantra of 'eat less, exercise more', but in the microbes already inside us.

Drawing on the latest science and his own pioneering research, Professor Tim Spector demystifies the common misconceptions about fat, calories, vitamins and nutrients. Only by understanding what makes our own personal microbes tick can we overcome the confusion of modern nutrition, and achieve a healthy gut and a healthy body.

Thomas Bewick (1753-1828) is synonymous with finely crafted wood engravings of the natural world, and his instantly recognisable style influenced book illustration well into the nineteenth century. During his childhood in the Tyne valley, his two obsessions were art and nature. At fourteen, he was apprenticed to the engraver and businessman Ralph Beilby (1743-1817) with whom he later published A General History of Quadrupeds (also reissued in this series). The present work, with its text compiled from various sources, was the first practical field guide for the amateur ornithologist, inspiring also artists and writers. Each of the two volumes contains hundreds of illustrations of breathtaking beauty and precision: one for each species, neatly capturing its character in exquisite detail, interspersed with charming vignettes of country life. Volume 2, first published in 1804, covers water birds, including sandpipers, terns, grebes and guillemots.

Ian Stewart's up-to-the-minute guide to the cosmos moves from the formation of the Earth and its Moon to the planets and asteroids of the solar system and from there out into the galaxy and the universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it will end. He considers parallel universes, what forms extra-terrestrial life might take, and the likelihood of Earth being hit by an asteroid. Mathematics, Professor Stewart shows, has been the driving force in astronomy and cosmology since the ancient Babylonians. He describes how Kepler's work on planetary orbits led Newton to formulate his theory of gravity, and how two centuries later irregularities in the motion of Mars inspired Einstein's theory of general relativity. In crystal-clear terms he explains the fundamentals of gravity, spacetime, relativity and quantum theory, and shows how they all relate to each other. Eighty years ago the discovery that the universe is expanding led to the Big Bang theory of its origins. This in turn led cosmologists to posit features such as dark matter and dark energy. But does dark matter exist? Could another scientific revolution be on the way to challenge current scientific orthodoxy? These are among the questions Ian Stewart raises in his quest through the realms of astronomy and cosmology.

Winner of the 2010 Royal Society Prize for science books Powerful new research methods are providing fresh and vivid insights into the makeup of life. Comparing gene sequences, examining the atomic structure of proteins and looking into the geochemistry of rocks have all helped to explain creation and evolution in more detail than ever before. Nick Lane uses the full extent of this new knowledge to describe the ten greatest inventions of life, based on their historical impact, role in living organisms today and relevance to current controversies. DNA, sex, sight and consciousnesses are just four examples. Lane also explains how these findings have come about, and the extent to which they can be relied upon. The result is a gripping and lucid account of the ingenuity of nature, and a book which is essential reading for anyone who has ever questioned the science behind the glories of everyday life.

Laki is Iceland's largest volcano. Its eruption in 1783 is one of history's great, untold natural disasters. Spewing out sun-blocking ash and then a poisonous fog for eight long months, the effects of the eruption lingered across the world for years. It caused the deaths of people as far away as the Nile and created catastrophic conditions throughout Europe. Island on Fire is the story not only of a single eruption but the people whose lives it changed, the dawn of modern volcanology, as well as the history and potential of other super-volcanoes like Laki around the world. And perhaps most pertinently, in the wake of the eruption of another Icelandic volcano, Eyjafjallajokull, which closed European air space in 2010, acclaimed science writers Witze and Kanipe look at what might transpire should Laki erupt again in our lifetime.

Penicillin is the drug of the twentieth century. It was the first of the antibiotics that, for decades after the Second World War, underpinned a popular belief that infectious disease had at last met its match. With the emergence of 'superbugs' in recent decades these hopes have faded. Across the world, we are warned that widespread antibiotic abuse will inexorably erode the drugs' efficacy and our own earlier confidence in them. Penicillin pulls these different but conjoined stories into a compelling narrative spanning the second half of the twentieth century. Using a wealth of new research, Robert Bud sets the discovery and use of penicillin in the broader context of social and cultural change across the world. He examines the drug's critical contributions to medicine and agriculture, and he investigates the global spread of resistant bacteria as antibiotic use continues to rise. Clearly written and highly topical, his book will be of great interest to historians, scientists, and anyone wishing to understand penicillin's seismic impact on modern life. Penicillin: Triumph and Tragedy Curated by Robert Bud A new exhibition looking back over 50 years will explore changing attitudes to antibiotics and launch at the Science Museum on Thursday 10 May 2007 . In the 1950s antibiotics were cast as wonder drugs, but strains of bacteria resistant to penicillin were already widespread. They caused many deaths, most dramatically, infecting hospitalised victims of Asian flu in the autumn of 1957. Now we fear MRSA. How have attitudes, hopes and fears changed in half a century?

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist? Introducing readers to important discoveries in animal behavior and evolution, "Odd Couples" explores some of the most extraordinary sexual differences in the animal world. From the fields of Spain to the deep oceans, evolutionary biologist Daphne Fairbairn uncovers the unique and bizarre characteristics--in size, behavior, ecology, and life history--that exist in these remarkable species and the special strategies they use to maximize reproductive success. Fairbairn describes how male great bustards aggressively compete to display their gorgeous plumage and large physiques to watching, choosey females. She investigates why female elephant seals voluntarily live in harems where they are harassed constantly by eager males. And she reveals why dwarf male giant seadevils parasitically fuse to their giant female partners for life. Fairbairn also considers humans and explains that although we are keenly aware of our own sexual differences, they are unexceptional within the vast animal world.

Looking at some of the most amazing creatures on the planet, "Odd Couples" sheds astonishing light on what it means to be male or female in the animal kingdom.

The book is unique in its emphasis on the road to scientific success rather than the science itself. Scientists communicate much on their science through research publications, but they tend to talk much less, if at all, on the challenges encountered on the road to success. Information on the road to scientific success is helpful to people that are considering embarking on the journey on this road or are in the middle of the journey on this road. These people need inspiration and encouragement. Unless the information is recorded, it would be lost.The objectives of this book series are to:

"Inspiring and informative...deserves to be widely read." -Wall Street Journal "This fun book offers a philosophical take on number systems and revels in the beauty of math." -Science News Because we have ten fingers, grouping by ten seems natural, but twelve would be better for divisibility, and eight is well suited to repeated halving. Grouping by two, as in binary code, has turned out to have its own remarkable advantages. Paul Lockhart presents arithmetic not as rote manipulation of numbers-a practical if mundane branch of knowledge best suited for filling out tax forms-but as a fascinating, sometimes surprising intellectual craft that arises from our desire to add, divide, and multiply important things. Passionate and entertaining, Arithmetic invites us to experience the beauty of mathematics through the eyes of a beguiling teacher. "A nuanced understanding of working with numbers, gently connecting procedures that we once learned by rote with intuitions long since muddled by education... Lockhart presents arithmetic as a pleasurable pastime, and describes it as a craft like knitting." -Jonathon Keats, New Scientist "What are numbers, how did they arise, why did our ancestors invent them, and how did they represent them? They are, after all, one of humankind's most brilliant inventions, arguably having greater impact on our lives than the wheel. Lockhart recounts their fascinating story... A wonderful book." -Keith Devlin, author of Finding Fibonacci

Swearing, it turns out, is an incredibly useful part of our linguistic repertoire. Not only has some form of swearing existed since the earliest humans began to communicate, but it has been shown to reduce physical pain, help stroke victims recover their language, and encourage people to work together as a team.

Swearing Is Good For You is a spirited and hilarious defence of our most cherished dirty words, backed by historical case studies and cutting-edge research. From chimpanzees creating their own curse words to a man who lost half his brain in a mining accident experiencing a new-found compulsion to swear, Dr Emma Byrne outlines the fascinating science behind swearing: how it affects us both physically and emotionally, and how it is more natural and beneficial than we are led to believe.

In What Do Animals Think and Feel?, the biologist Karsten Brensing has something astonishing to tell us about the animal kingdom: namely that animals, by any reasonable assessment, have developed the sophisticated systems of social organization and behaviour that human beings call 'culture'. Dolphins call one another by name and orcas inhabit a culture that is over 700,000 years old. Chimpanzees wage strategic warfare, while bonobos delight in dirty talk. Ravens enjoy snowboarding on snow-covered roofs, and snails like to spin on hamster exercise wheels. Humped-back whales follow the dictates of fashion and rats are dedicated party animals. Ants recognize themselves in mirrors and spruce themselves up before they return home. Ducklings can pass complicated tests in abstract thinking. Dogs punish disloyalty, though they are also capable of forgiveness if you apologize to them. Brensing draws on the latest scientific findings as well as his own experience working with animals, to reveal a world of behavioural and cognitive sophistication that is remarkably similar to our own.

A gritty, dark tale of infectious disease gone wrong - the timely graphic novel from Sunday Times bestselling author Val McDermid, stunningly illustrated by Kathryn Briggs 'A brilliant and timely story, told with McDermid's verve, style and passion. I couldn't stop turning the pages, even when I could barely take the tension. Wonderful.' Denise Mina It's the summer solstice weekend, and 150,000 people descend on a farm in the northeast of England for an open-air music festival. At first, a spot of rain seems to be the only thing dampening the fun - until a mystery bug appears. Before long, the illness is spreading at an electrifying speed and seems resistant to all antibiotics. Can journalist Zoe Meadows track the outbreak to its source, and will a cure be found before the disease becomes a pandemic? A heart-racing thriller, Resistance imagines a nightmare pandemic that seems only too credible in the wake of COVID-19. Number one bestseller and queen of crime Val McDermid has teamed up with illustrator Kathryn Briggs to create a masterful graphic novel.

This book explains, in simple terms, with a minimum of mathematics, why things can appear to be in two places at the same time, why correlations between simultaneous events occurring far apart cannot be explained by local mechanisms, and why, nevertheless, the quantum theory can be understood in terms of matter in motion. No need to worry, as some people do, whether a cat can be both dead and alive, whether the moon is there when nobody looks at it, or whether quantum systems need an observer to acquire definite properties. The author's inimitable and even humorous style makes the book a pleasure to read while bringing a new clarity to many of the longstanding puzzles of quantum physics.

What do proteins and pop-up cards have in common? How is opening a grocery bag different from opening a gift box? How can you cut out the letters for a whole word all at once with one straight scissors cut? How many ways are there to flatten a cube? You can answer these questions and more through the mathematics of folding and unfolding. From this book, you will discover new and old mathematical theorems by folding paper and find out how to reason toward proofs. With the help of 200 color figures, author Joseph O'Rourke explains these fascinating folding problems starting from high school algebra and geometry and introducing more advanced concepts in tangible contexts as they arise. He shows how variations on these basic problems lead directly to the frontiers of current mathematical research and offers ten accessible unsolved problems for the enterprising reader. Before tackling these, you can test your skills on fifty exercises with complete solutions. The book's Web site, http: //www.howtofoldit.org, has dynamic animations of many of the foldings and downloadable templates for readers to fold or cut out.

Presents the current view of quantum biology Presents central topics via introductory anecdotes Combines scientifically correct explanations and a popular language Demystifies quantum physics Provides standard and most recent references and recommended reading Includes a dictionary explaining central concepts

A fresh look at electricity and its powerful role in life on Earth When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices-or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical. The story of how we came to understand electricity's essential role in all life is rooted in our observations of its influences on the body-influences governed by the body's central nervous system. Spark explains the science of electricity from this fresh, biological perspective. Through vivid tales of scientists and individuals-from Benjamin Franklin to Elon Musk-Timothy Jorgensen shows how our views of electricity and the nervous system evolved in tandem, and how progress in one area enabled advancements in the other. He explains how these developments have allowed us to understand-and replicate-the ways electricity enables the body's essential functions of sight, hearing, touch, and movement itself. Throughout, Jorgensen examines our fascination with electricity and how it can help or harm us. He explores a broad range of topics and events, including the Nobel Prize-winning discoveries of the electron and neuron, the history of experimentation involving electricity's effects on the body, and recent breakthroughs in the use of electricity to treat disease. Filled with gripping adventures in scientific exploration, Spark offers an indispensable look at electricity, how it works, and how it animates our lives from within and without.
