A virologist's insight into how viruses evolve and why global epidemics are inevitable

The extraordinary role of viruses in evolution and how this is revolutionising biology and medicine.Darwin's theory of evolution is still the greatest breakthrough in biological science. 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 is the product of Dr Frank Ryan's decade of research at the frontiers of this new science - now called viral symbiosis - and the amazing revolution that it has had in these few years. As scientists begin to look for evidence of viral involvement in more and more processes, they have discovered that they are vital in nearly every case. And with this understanding comes the possibility of manipulating the role of the viruses to help fight a huge range of diseases.

Asperger syndrome (AS), also known as Asperger's syndrome, Asperger disorder (AD) or simply Asperger's, is an autism spectrum disorder (ASD) that is characterized by significant difficulties in social interaction and nonverbal communication, alongside restricted and repetitive patterns of behavior and interests. It differs from other autism spectrum disorders by its relative preservation of linguistic and cognitive development.Many people are afflicted with and suffer from Asperger's and there is little to no understanding by the general public in regards to this syndrome. There is a lack of awareness, so when people encounter someone who has Asperger's they view them strangely because aspies (as they commonly refer to themselves as) act and communicate differently from the rest of society so they are easily misunderstood.In his book entitled "Asperger Syndrome" author and Asperger expert Frank Ryan offers a comprehensive guide for understanding, living with and treating Asperger syndrome.Here are some of the topics covered: - Detail overview and history of the Asperger Syndrome- Effects of the syndrome on social interactions- Effects of the syndrome on behavior and interests- Effects of the syndrome on speech and language- Effects of the syndrome on motor and sensory perception- Therapies and medication- Alternative therapies and treatments- Available aids- Children who suffer from Asperger- Adults who suffer from Asperger- How to deal with and manage a loved one who has AspergerAnd much more......

Tuberculosis - the greatest killer of all time - has claimed more than a billion lives worldwide. Dr. Frank Ryan tells the remarkable story of the handful of dedicated doctors, chemists and bacteriologists who searched for and found a cure for this ferocious disease - an extraordinary detective feat that owed as much to luck and intuition as to any systematic scientific process. But a story that once ended in triumph now carries a dire warning, for the "old enemy" has found a new ally - AIDS - creating a deadly drug-resistant synergy that is ravaging the globe. As we face one of the worst epidemics of all time, no story could be more relevant.

A fascinating and long overdue examination of viruses - from what they are and what they do, to the vital role they have played in human history.What are viruses? Do they rely on genes, like all other forms of life? Do they follow the same patterns of evolution as plants and animals?Dr. Frank Ryan answers these questions and many more in a sweeping tour of illnesses caused by viruses. He examines the common cold, measles, chicken pox, herpes, mumps, and rubella, as well as less familiar maladies, such as rabies, "breakbone fever," hemorrhagic fevers like Ebola, and virus-induced cancers. Along the way, readers will learn about the behaviors of viruses and what drives them to infect a human host. Ryan explains the role of viruses in the evolution of life, revealing how viruses have changed us at the most intimate level, helping to make us quintessentially human.

How could a relatively simple chemical code give rise to the complexity of a human being? How could our human genome have evolved? And how does it actually work?Over the past 50 years we have deciphered the inner workings of the human genome. From the basic structure of DNA through to the complete sequence of the code, what first appeared to be simple is actually a complex and beautiful three-dimensional world that makes each of us who we are.In The Mysterious World of the Human Genome acclaimed science writer Frank Ryan leads us through the most exciting scientific discoveries of the last 50 years, revealing how this science has unlocked the cure of some genetic diseases, developed the use of DNA in forensic science and paternity testing, helped us trace our ancestors and provided a definitive map for the movement of humans out of Africa. This scientific journey has had a profound impact on our understanding of the evolution of life itself, through the role of the most ancient of organisms in our basic biology all the way to the revelation that our most recent ancestor, Homo neanderthalensis, lives on in many of us.In the ever more complicated world of the human genome, this is the first book to explain how the human genome actually works as a whole and how that knowledge will have a profound effect on our understanding of where we have come from and where we are likely to be going in the future.

In this enchanting work of scientific exploration, acclaimed science author Frank Ryan explains how metamorphosis - the intricate trick of nature by which caterpillars transform into butterflies - reveals secrets that are shaking the scientific world. Ryan brings to life the work of pioneering naturalists who have traced metamorphosis in myriad species, from amphibians to marine creatures, even human puberty, to rewrite some of our longest-held beliefs about evolution. Lyrical and provocative, The Mystery of Metamorphosis offers a new understanding of some of the most ancient miracles of the nature.
