His explanation of the role of natural selection in driving the evolution of life on earth depended on steady variation of living things over time – but he was unable to explain how this variation occurred. In the 150 years since publication of the Origin of Species, we have discovered three main sources for this variation – mutation, hybridisation and epigenetics. Then on Sunday, 12th February, 2001 the evidence for perhaps the most extraordinary cause of variation was simultaneously released by two organisations – the code for the entire human genome. Not only was the human genome unbelievably simple (it is only ten times more complicated than a bacteria), but embedded in the code were large fragments that were derived from viruses – fragments that were vital to evolution of all organisms and the evidence for a fourth and vital source of variation – viruses.Virolution was the subject of a feature article in New Scientist. Translated into Russian, French, German and Japanese, this book has become a hot topic for discussion among scientists and thinkers in recent years. It offers a very new interpretation of our human evolution - and extrapolates to new avenues of approach to fight important diseases, such as cancer and MS.In early 2014 Dr Ryan has co-authored a relevant new paper with Swedish and Chinese scientists working on the Human Proteome project. More details about this paper and other developments will follow in his articles and blogs. So popular is the topic he has been commissioned to give a plenary lecture followed by planning and research advice to PhD students in biology and evolutionary biology at the annual European Society for Evolutionary Biology annual meeting for PhD students in Belgium in September 2014.More anon...

    Together, they explain virtually everything about the world we live in. But, almost a century after their advent, most people haven't the slightest clue what either is about. Did you know that there's so much empty space inside matter that the entire human race could be squeezed into the volume of a sugar cube? Or that you grow old more quickly on the top floor of a building than on the ground floor? And did you realize that 1 per cent of the static on a TV tuned between stations is the relic of the Big Bang? These and many other remarkable facts about the world are direct consequences of quantum physics and relativity. Quantum theory has literally made the modern world possible. Not only has it given us lasers, computers, and nuclear reactors, but it has provided an explanation of why the sun shines and why the ground beneath our feet is solid. Despite this, however, quantum theory and relativity remain a patchwork of fragmented ideas, vaguely understood at best and often utterly mysterious. average person. Author Marcus Chown emphatically disagrees. As Einstein himself said, Most of the fundamental ideas of science are essentially simple and may, as a rule, be expressed in a language comprehensible to everyone. If you think that the marvels of modern physics have passed you by, it is not too late. In Chown's capable hands, quantum physics and relativity are not only painless but downright fun. So sit back, relax, and get comfortable as an adept and experienced science communicator brings you quickly up to speed on some of the greatest ideas in the history of human thought.

    As well as lucid descriptions of all the topics and many worked examples, it contains over 800 exercises. New stand-alone chapters give a systematic account of the 'special functions' of physical science, cover an extended range of practical applications of complex variables, and give an introduction to quantum operators. Further tabulations, of relevance in statistics and numerical integration, have been added. In this edition, half of the exercises are provided with hints and answers and, in a separate manual available to both students and their teachers, complete worked solutions. The remaining exercises have no hints, answers or worked solutions and can be used for unaided homework; full solutions are available to instructors on a password-protected web site, www.cambridge.org/9780521679718.

    Distinguishing agents (e.g., molecules, cells, animals, and species) from their interactions (e.g., chemical reactions, immune system responses, sexual reproduction, and evolution), Flake argues that it is the computational properties of interactions that account for much of what we think of as beautiful and interesting. From this basic thesis, Flake explores what he considers to be today's four most interesting computational topics: fractals, chaos, complex systems, and adaptation.Each of the book's parts can be read independently, enabling even the casual reader to understand and work with the basic equations and programs. Yet the parts are bound together by the theme of the computer as a laboratory and a metaphor for understanding the universe. The inspired reader will experiment further with the ideas presented to create fractal landscapes, chaotic systems, artificial life forms, genetic algorithms, and artificial neural networks.

    With the pressures of choosing a practical future path bearing down, she needs a drastic change. Too old to run away from home, she opts instead to embark on a solo 2-month road trip. But her freedom is tempered by loneliness - and anxiety tests her resolve as she comes face-to-face with her quirky internet friends. Aside from contracting mono and repeatedly getting herself lost, Angeli's adventure is mired by more unforeseen glitches - like being detained by Canadian authorities, and a near-death experience at the hands of an overzealous amateur wrestler. Her odyssey is complicated further when she unwittingly earns the affections of two young men. One a privileged martial artist; the other a talented techie with a colorful past. Bewildered by the emotions they stir, Angeli spurns the idea of a doomed long-distance relationship. But she is unprepared for the determination of her hopeful suitors. In the wake of her refusal, one man will betray her, and the other will prove himself worthy of a place in her future. Angeli sets off in search of a better understanding of herself, the world, and her place in it. What she finds is an impractical love, with the potential to restore her faith in happy endings. A true story with an unapologetically honest outlook on life, love, faith, and adventure - Once Upon A Road Trip is a coming-of-age memoir.

    In this spirit, the team at NASA set about developing the Space Shuttle, arguably the most complex piece of machinery ever created. The world’s first reusable spacecraft, it launched like a rocket, landed like a glider, and carried out complicated missions in between.  Bold They Rise tells the story of the Space Shuttle through the personal experiences of the astronauts, engineers, and scientists who made it happen—in space and on the ground, from the days of research and design through the heroic accomplishments of the program to the tragic last minutes of the Challenger disaster. In the participants’ own voices, we learn what so few are privy to: what it was like to create a new form of spacecraft, to risk one’s life testing that craft, to float freely in the vacuum of space as a one-man satellite, to witness a friend’s death. A “guided tour” of the Shuttle—in historical, scientific, and personal terms—this book provides a fascinating, richly informed, and deeply personal view of a feat without parallel in the human story.
