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....

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 fertilised egg is a living person, for example, and when we ought to declare a person legally dead.

In Air-borne, Carl Zimmer, Baillie Gifford-shortlisted author of She Has Her Mother’s Laugh and science columnist for The New York Times, traces the history and pre-history of the young science of aerobiology, from Antonie van Leeuwenhoek’s discovery of microbes under his hand-made microscopes in the seventeenth century to Darwin’s revelation, while aboard the Beagle in the middle of the Atlantic, that this invisible life can soar across the planet – he found sixty-seven different North African species that had travelled thousands of miles from the Sahara.

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.

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.
