    Nessa Carey's THE EPIGENETICS REVOLUTION looks at how modern biology is rewriting our understanding of genetics, disease and inheritance. 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 we still don't even know all the questions. The Epigenetics Revolution traces the thrilling path that epigenetics has taken over the last twenty years. Biologist Nessa Carey deftly explains such diverse phenomena as how queen bees control their colonies, why...read more

    For decades after the identification of the structure of DNA, scientists focused only on genes, the regions of the genome that contain codes for the production of proteins. Other regions that make up 98 percent of the human genome were dismissed as 'junk,' sequences that serve no purpose. But researchers have recently discovered variations and modulations in this junk DNA that are involved with a number of intractable diseases. Junk DNA can play vital and unanticipated roles in the control of gene expression, from fine-tuning individual genes to switching off entire chromosomes. These functions have forced scientists to revisit the very meaning of the word 'gene' and have engendered a...read more

    Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female;...read more

    Just 45 years ago, the age of gene modification was born. Researchers could create glow-in-the-dark mice, farmyard animals producing drugs in their milk, and vitamin-enhanced rice that could prevent half a million people going blind every year. But now GM is rapidly being supplanted by a new system called CRISPR or ‘gene editing’. Using this approach, scientists 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 even...read more

    From the author of the acclaimed The Epigenetics Revolution comes another thrilling exploration of the cutting edge of human science. For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of proteins. Other regions - 98% of the human genome - were dismissed as 'junk'. But in recent years researchers have discovered that variations in this 'junk' DNA underlie many previously intractable diseases, and they can now generate new approaches to tackling them. Nessa Carey explores the incredible story behind a controversy that has generated unusually vituperative public exchanges between...read more
