In 2018, the first genetically modified babies were reportedly born in China, made possible by the invention of CRISPR technology in 2012. This controversial advancement overturned the preexisting moral consensus, which had held for over 50 years before: While gene editing an adult person was morally acceptable, modifying babies, and thus subsequent generations, crossed a significant moral line. John H. Evans here provides a meta-level guide to how these debates move forward and their significance to society.

Resistance to malaria. Blue eyes. Lactose tolerance. What do all of these traits have in common? Every one of them has emerged in the last 10,000 years.

Since 2010, it has been possible to determine a person's genetic makeup in a matter of days at an accessible cost for many millions of people. Along with this technological breakthrough there has emerged a movement to use this information to help prospective parents "eliminate preventable genetic disease". As the prospect of systematically excluding the appearance of unwanted mutations in our children comes within reach, David B. Goldstein examines the possible consequences from these types of choices.

Una piccola sigla, un mondo di significati: il DNA è una risorsa contro le malattie, uno strumento per identificare gli assassini e una chiave per comprendere il comportamento umano. La sua storia è talmente antica da intrecciarsi con quella della comparsa della vita sulla Terra. E in futuro? Proviamo a parlarne direttamente con lui. Dalla genetica di Neandertal alla clonazione di esseri umani, metteremo a fuoco speranze (e timori) che grazie al DNA si aprono per la scienza e per le nostre esistenze.

In the book Diet and Health, I explained what brought us to our current state of 40 percent obesity in the Western world. My goal is to prevent type 2 diabetes, and to do that, I have to prevent obesity. I compared our historical diet to the modern Western diet, and showed how the modern diet has induced insulin resistance. I offered treatment for those who are obese or have pre-diabetes. I then described the various maintenance diets. If you already have type 2 diabetes, I can help you control it.

"Egoístas, inmortales y viajeras" explora el pasado, la realidad actual y el futuro de una enfermedad que, en términos estrictos, no es una única entidad sino más de doscientas distintas, tantas como tipos celulares construyen los diferentes órganos y tejidos de nuestro cuerpo. Discutiremos en primer lugar el origen del cáncer, una cuestión que hasta una fecha reciente no tuvo una respuesta concreta y de la que hoy podemos decir que es una enfermedad de los genes en el planeta de los genes.

The emergence of genomic science in the last quarter century has revolutionized medicine, the justice system, and our understanding of who we are. We use genomics to determine guilt and exonerate the falsely convicted; devise new medicines; test embryos; and discover our ethnic and national roots. One might think that, given these advances, most would favor the availability of genomic tools. Yet as Jennifer Hochschild explains in Genomic Politics, the uses of genomic science are both politically charged and hotly contested.

While in the world of literature and film, mad scientists create monsters like "Frankenstein” and almost all religions are promoting skepticism towards science and the fear of manipulating human beings, reality has bypassed such concerns long ago. Osho has a unique view – supporting science, specifically genetic science – but as a conscious science.

Was ist Leben? Und was bedeutet die Antwort auf diese Frage für die Herausforderungen, denen sich die Menschheit heute gegenübersieht - Klimawandel, Pandemien und Artensterben? Paul Nurse erhielt den Nobelpreis dafür, gezeigt zu haben, wie lebende Zellen funktionieren. In seinem so klar wie elegant verfassten Buch synthetisiert er auf wenigen Seiten sämtliches Wissen darüber, was es heißt, am Leben zu sein. Schritt für Schritt erläutert Nurse die fünf revolutionären Ideen, die der Biologie zugrunde liegen - die Zelle, das Gen, Evolution durch natürliche Selektion, das Leben als Chemie und das Leben als Information.

In The Genetic Lottery, Harden introduces listeners to the latest genetic science, dismantling dangerous ideas about racial superiority and challenging us to grapple with what equality really means in a world where people are born different. Weaving together personal stories with scientific evidence, Harden shows why our refusal to recognize the power of DNA perpetuates the myth of meritocracy, and argues that we must acknowledge the role of genetic luck if we are ever to create a fair society.

The discovery of DNA’s structure is the story of five towering minds in pursuit of the advancement of science, and for almost all of them, the prospect of fame and immortality: Watson, Crick, Rosalind Franklin, Maurice Wilkins, and Linus Pauling. Howard Markel skillfully recreates the intense intellectual journey, and fraught personal relationships, that ultimately led to a spectacular breakthrough. But it is Rosalind Franklin - fiercely determined, relentless, and an outsider at Cambridge and the University of London in the 1950s - who becomes a focal point for Markel.

Today, with relatively easy access to our DNA ancestry, we have more data about ourselves and family history than previous generations could have imagined. In the 12 fascinating lessons of Identity in the Age of Ancestral DNA, Anita Foeman, PhD, professor of communication and media, and founder and primary investigator of the DNA Discussion Project at West Chester University, takes us behind the scenes to examine what really happens when individuals receive their personal DNA ancestry results.

I nostri geni non sono scolpiti nella pietra e i nostri fattori ereditari non sono un' "impronta digitale" fissa e immodificabile. Un essere umano infatti è molto più della somma dei suoi geni. Tutto quello che mangiamo, facciamo e sentiamo, tutto ciò che ci accade può influire sull'attività del DNA, a prescindere dalla configurazione genetica con la quale nasciamo. L'epigenetica, cioè la branca della genetica che si occupa di indagare le variazioni dell'espressione del nostro DNA, ci porta infatti una buona notizia: tali variazioni sono reversibili.

I’ve written a number of books on longevity and immortality. But I’ve only had some partial chapters on long-lived plants and animals. This is an important subject because all of this life is based on the same DNA code we have in our own bodies. If this life can live for hundreds or thousands of years, then this says that it is possible for humanity to live that long, also. Here I’ve researched and included lots of specimens of animal and plant life which represent the extremes of longevity for widely varying life.

The Secret Body is a gripping drama of discovery and a landmark account of the dawning revolution in human health that reveals a hitherto invisible universe within each of us.

Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human - big breakthroughs that made whole new ways of life possible - including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air.

In November 2018, the world was shocked to learn that two babies had been born in China with DNA edited while they were embryos - as dramatic a development in genetics as the cloning of Dolly the sheep was in 1996. In this book, Hank Greely, a leading authority on law and genetics, tells the fascinating story of this human experiment and its consequences. Greely explains what Chinese scientist He Jiankui did, how he did it, and how the public and other scientists learned about and reacted to this unprecedented genetic intervention.

Since the dawn of humankind, mental illness has been one of our greatest causes of suffering as a species. But for the majority of our history, its causes have remained a mystery. Professor Karl Deisseroth shares his breakthrough discovery, optogenetics, a biological technique that allows us to decipher the brain's inner workings using light. With moving and revelatory stories from both personal and professional experience, he reveals what mental illnesses really are, why we suffer from them and the unexpected role they have played in our evolution.

Brian and Deborah Charlesworth provide a clear and concise summary of the process of evolution by natural selection, and how natural selection gives rise to adaptations and eventually, over many generations, to new species. They introduce the central concepts of the field of evolutionary biology, as they have developed since Darwin and Wallace on the subject, over 140 years ago, and discuss some of the remaining questions regarding processes.

DEL AUTOR DEL BESTSELLER "LA VIDA EN CUATRO LETRAS". "El sueño del tiempo" surge de la constatación de que, aunque la física y la filosofía nos enseñan que el flujo del tiempo puede ser solo una fantasía creada por nuestra mente, el tiempo biológico vive en nosotros y nosotros vivimos en el tiempo del mundo.
