What happens when your family tells you one thing, but a DNA test tells you another? Georgina Lawton grew up in a loving family but she didn’t look like anyone else. She has dark eyes, curly hair and brown skin. Both her parents were white. Georgina took a DNA test. The results changed her life forever. With millions around the world using 'do-it-yourself' DNA testing kits, Georgina follows the stories of those learning to live with the results.

Walter Isaacson vertelt het verhaal van DNA-expert en Nobelprijswinnaar Jennifer Doudna. In oktober 2020 ontving biochemicus Jennifer Doudna samen met haar collega Emmanuelle Charpentier de Nobelprijs voor de Scheikunde voor hun doorslaggevende bijdrage aan de ontwikkeling van CRISPR-Cas. Met deze techniek kunnen wetenschappers het menselijk genoom bewerken door te knippen en plakken in DNA-sequenties.

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.

Hace 13.000 años la evolución de las distintas sociedades humanas comenzó a tomar rumbos diferentes. La temprana domesticación de animales y el cultivo de plantas silvestres en el Creciente Fértil, China, Mesoamérica y otras zonas geográficas otorgó una ventaja inicial a sus habitantes. Sin embargo, los orígenes localizados de la agricultura y la ganadería son solo una parte de la explicación de los diferentes destinos. Las sociedades que superaron esta fase de cazadores-recolectores se encontraron con más probabilidades de desarrollo, supervivencia y poder bélico.

Un estudio que cambia las reglas del juego. Es un hecho que las mujeres viven más que los hombres, tienen un sistema inmunitario más fuerte, son mejores para combatir el cáncer y otras enfermedades y sobrevivir en caso de hambruna; incluso ven el mundo en una variedad más amplia de colores. Son simplemente más fuertes que los hombres en todas las etapas de la vida. ¿Por qué? ¿Y por qué nos enseñan lo contrario?

Wissenschaftlichen Schätzungen zufolge leidet jeder Mensch unter mindestens 2.000 Gendefekten. Sie lassen unser Immunsystem schlechter funktionieren, führen zu Arthrose und Osteoporose, können Diabetes und Sehschwäche verursachen, und sie machen dick. Aber Gene sind kein Schicksal mehr. Der Molekularbiologe Dr. Daniel Wallerstorfer zeigt, wie wir mit der richtigen Vorsorge, guter Ernährung und dem geeigneten Lebensstil unsere Erbanlagen steuern und unsere Gesundheit kontrollieren können.

Draghi, ciclopi, giganti, unicorni, fenici. Quando gli antichi si imbattevano in resti di animali sconosciuti, subito li attribuivano a creature fantastiche. Poi gli scienziati hanno dimostrato che si trattava solo di fantasie ancestrali: i mostri non esistono, oggi lo sappiamo tutti; eppure la spiegazione che gli studiosi hanno dato di quei reperti è stata addirittura più terrificante: prima di noi, una miriade di altri viventi abitava il nostro pianeta, ma ora non ci sono più. Sulla Terra, infatti, nulla è per sempre.

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.

« Biologie des croyances » est une œuvre révolutionnaire dans le domaine de la nouvelle biologie. Chercheur et ex-professeur d'une école de médecine, Bruce H. Lipton, Phd., présente ses expériences et celles d'autres scientifiques de pointe qui ont examiné en détail les mécanismes par lesquels les cellules reçoivent et traitent les informations. Les implications de ces recherches changent radicalement notre compréhension de la vie en démontrant que les gènes et l'ADN ne contrôlent pas notre fonctionnement biologique.

In the aftermath of an asteroid impact, Earth’s power grid is damaged nearly beyond recovery. The survival of our world may well depend on energy sources collected from an abandoned undersea settlement beneath the icy surface of Enceladus. Earth-raised Colonel Carter Rhodes, in charge of Earth’s recovery efforts, calls upon Gwen Baré, a Venusian engineer, to regain control of the deserted moon outpost and collect fuel for Earth’s collapsing power grids.

Are humans close to living forever? With advances in medicine and new therapies that prolong life expectancy, we are on track to make aging even more manageable. This new entry in the exciting Alice in Futureland series explores both the science and cultural impulse behind extending lifespans, and the numerous ways the quest for eternity forces us to reevaluate what it means to be human. Some experts believe that we haven’t fully realized our true human potential, and we are about to embark on an extraordinary evolutionary shift.

While plenty of entertaining books have been written about the history of alcohol and other intoxicants, none have offered a comprehensive, convincing answer to the basic question of why humans want to get high in the first place. Drunk elegantly cuts through the tangle of urban legends and anecdotal impressions that surround our notions of intoxication to provide the first rigorous, scientifically grounded explanation for our love of alcohol.

Cystic fibrosis was once a mysterious disease that killed infants and children. Now it could be the key to healing millions with genetic diseases of every type - from Alzheimer's and Parkinson's to diabetes and sickle cell anemia. Told from the perspectives of the patients, families, physicians, scientists, and philanthropists fighting on the front lines, Breath from Salt is a remarkable story of unlikely scientific and medical firsts, of setbacks and successes, and of people who refused to give up hope....

In From Darwin to Derrida, evolutionary biologist David Haig explains how a physical world of matter in motion gave rise to a living world of purpose and meaning. Natural selection, a process without purpose, gives rise to purposeful beings who find meaning in the world. The key to this, Haig proposes, is the origin of mutable “texts”―genes―that preserve a record of what has worked in the world. These texts become the specifications for the intricate mechanisms of living beings.

How did humans, a species of self-centered apes, come to care about others? Since Darwin, scientists have tried to answer this question using evolutionary theory. In The Kindness of Strangers, psychologist Michael E. McCullough shows why they have failed and offers a new explanation instead. From the moment nomadic humans first settled down until the aftermath of the Second World War, our species has confronted repeated crises that we could only survive by changing our behavior.

Mary Anning was only 12 years old when, in 1811, she discovered the first dinosaur skeleton - of an ichthyosaur - while fossil hunting on the cliffs of Lyme Regis, England. Until Mary's incredible discovery, it was widely believed that animals did not become extinct.

What is animal welfare? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as "health and animals having what they want", a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we need to collect to improve animal welfare in practice. Above all, it puts the animal's own point of view at the heart of an assessment of its welfare.

In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed - a toxic plant named for the sticky white substance emitted when its leaves are damaged - and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.

In The Genealogical Adam and Eve, S. Joshua Swamidass tests a scientific hypothesis: What if the traditional account is somehow true, with the origins of Adam and Eve taking place alongside evolution? Building on well-established but overlooked science, Swamidass explains how it's possible for Adam and Eve to be rightly identified as the ancestors of everyone.
