Nessa Carey - Böcker

'A book that would have had Darwin swooning - anyone seriously interested in who we are and how we function should read this.' Guardian At the beginning of this century enormous progress had been made in genetics. The Human Genome Project finished sequencing human DNA. It seemed it was only a matter of time until we had all the answers to the secrets of life on this planet.The cutting-edge of biology, however, is telling us that we still don't even know all of the questions.How is it that, despite each cell in your body carrying exactly the same DNA, you don't have teeth growing out of your eyeballs or toenails on your liver? How is it that identical twins share exactly the same DNA and yet can exhibit dramatic differences in the way that they live and grow?It turns out that cells read the genetic code in DNA more like a script to be interpreted than a mould that replicates the same result each time. This is epigenetics and it's the fastest-moving field in biology today.The Epigenetics Revolution traces the thrilling path this discipline has taken over the last twenty years. Biologist Nessa Carey deftly explains such diverse phenomena as how queen bees and ants control their colonies, why tortoiseshell cats are always female, why some plants need a period of cold before they can flower, why we age, develop disease and become addicted to drugs, and much more. Most excitingly, Carey reveals the amazing possibilities for humankind that epigenetics offers for us all - and in the surprisingly near 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

For decades, 98 per cent of our DNA was written off as 'junk' on the grounds that it did not code for proteins.From rare genetic diseases to Down's Syndrome, from viral infections to the ageing process, only now are the effects and the vital functions of these junk regions beginning to emerge. Scientists' rapidly growing knowledge of this often controversial field has already provided a successful cure for blindness and saved innocent people from death row via DNA fingerprinting, and looks set to revolutionise treatment for many medical conditions including obesity.From Nessa Carey, author of the acclaimed The Epigenetics Revolution, this is the first book for a general readership on a subject that may underpin the secrets of human complexity - even the very origins of life on earth.
