For centuries, parasites have lived in nightmares, horror stories, and the darkest shadows of science. In Parasite Rex, Carl Zimmer takes listeners on a fantastic voyage into the secret universe of these extraordinary life forms that are not only among the most highly evolved on Earth, but make up the majority of life's diversity. Traveling from the steamy jungles of Costa Rica to the parasite-riddled war zone of southern Sudan, Zimmer introduces an array of amazing creatures that invade their hosts, prey on them from within, and control their behavior.

What caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

In 2020, an invisible germ - a virus - wholly upended our lives. We're most familiar with the viruses that give us colds or Covid-19. But viruses also cause a vast range of other diseases, including one disorder that makes people sprout branch-like growths as if they were trees. Viruses have been a part of our lives for so long that we are actually part virus: the human genome contains more DNA from viruses than our own genes. Meanwhile, scientists are discovering viruses everywhere they look: in the soil, in the ocean, even in deep caves miles underground.

Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.

She Has Her Mother's Laugh presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. We need a new definition of what heredity is and, through Carl Zimmer's lucid exposition and storytelling, this resounding tour de force delivers it.

“What's most compelling about a scientific story is the way it challenges us to think about the concepts we take for granted,” writes guest editor Carl Zimmer in his introduction. The essays in this year’s Best American Science and Nature Writing probe at the ordinary and urge us to think more deeply about our place in the world around us.

Desde las junglas húmedas de Costa Rica hasta el fétido entorno de las zonas rebeldes del sur de Sudán, Carl Zimmer nos guía a través de un viaje por el universo de los parásitos, un mundo en el que habitamos sin ser conscientes. Así nos descubre no solo la forma de vida más exitosa del planeta, sino aquella que da forma a los ecosistemas y es el motor de la evolución. Zimmer nos muestra, pues, cuánto han evolucionado estos bichos, y relata la aterradora facilidad con que pueden devorar a quien los hospeda, e incluso controlar su conducta.

Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilised egg is a living person, for example, and when we ought to declare a person legally dead.

She Has Her Mother’s Laugh presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities....

"Mientras escribo esto, a lo largo del año 2015, los científicos intentan adelantarse a las próximas pandemias. Nadie es capaz de predecir cuándo una cepa en particular llevará a cabo el salto, si acaso lo hará. Sin embargo, no estamos indefensos ante lo que la evolución pueda tenernos reservado. Contamos con recursos para contrarrestar la expansión de la gripe, como lavarnos las manos. Y los científicos están aprendiendo a fabricar vacunas más efectivas. Al menos, ya no tenemos que mirar hacia las estrellas en busca de protección." — Carl Zimmer

The Los Angeles Times Festival of Books began in 1996 with a simple goal: to bring together the people who create books with the people who love to read them. The festival was an immediate success and has become the largest and most prestigious book festival in the country, attracting more than 130,000 book lovers each year.

Carl Zimmer prezintă cele mai recente cercetări despre modul în care virușii guvernează întreaga noastră existență, modul în care au contribuit la nașterea primelor forme de viață, cum contribuie la producerea de noi boli, cum putem valorifica virușii pentru propriile noastre scopuri și cum virușii vor continua să influențeze soarta omenirii în anii următori.
