Carl Zimmer

Los parásitos son las formas vivas más exitosas de la Tierra, sino que también han favorecido el desarrollo del sexo, han dado forma a los ecosistemas, y han sido el motor de la evolución.A la hora de describir el universo de los parasitos, Zimmer realiza la increible afirmacion de que la mayoria de las especies son parasitas, y de que practicamente todos los animales, incluyendo a los humanos, seran en uno u otro momento el hogar de alguno de ellos. Zimmer muestra cuanto han evolucionado los parasitos y describe la aterradora y asombrosa ingenuidad con que estos comandos invasores suelen devorar a sus hospedadores desde su interior y controlar su conducta.

Combining the literary sensibility of David Quammen with the scientific rigor of Stephen Jay Gould, Carl Zimmer reveals the power, danger, and beauty of the surprising creatures who dominate the earth: parasites.For centuries, parasites have lived in nightmares, horror stories, and the darkest shadows of science. In Parasite Rex, Carl Zimmer takes readers on a fantastic voyage into the secret universe of these extraordinary life-formswhich are not only among the most highly evolved on Earth, but make up the majority of lifes 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. He also vividly describes parasites that can change DNA, rewire the brain, make men more distrustful and women more outgoing, and turn hosts into the living dead. This comprehensive, gracefully written book brings parasites out into the open and uncovers what they can teach us all about the most fundamental survival tactics in the universethe laws of Parasite Rex.

Everybody Out of the PondAt the Waters Edge will change the way you think about your place in the world. The awesome journey of lifes transformation from the first microbes 4 billion years ago to Homo sapiens today is an epic that we are only now beginning to grasp. Magnificent and bizarre, it is the story of how we got here, what we left behind, and what we brought with us. We all know about evolution, but it still seems absurd that our ancestors were fish. Darwins idea of natural selection was the key to solving generation-to-generation evolution -- microevolution -- but it could only point us toward a complete explanation, still to come, of the engines of macroevolution, the transformation of body shapes across millions of years. Now, drawing on the latest fossil discoveries and breakthrough scientific analysis, Carl Zimmer reveals how macroevolution works. Escorting us along the trail of discovery up to the current dramatic research in paleontology, ecology, genetics, and embryology, Zimmer shows how scientists today are unveiling the secrets of life that biologists struggled with two centuries ago. In this book, you will find a dazzling, brash literary talent and a rigorous scientific sensibility gracefully brought together. Carl Zimmer provides a comprehensive, lucid, and authoritative answer to the mystery of how nature actually made itself.

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. Nos descubre que no solo son las formas de vida mas exitosas de la Tierra, sino que favorecen el desarrollo del sexo, dan forma a los ecosistemas y son el motor de la evolucion. Zimmer muestra cuanto han evolucionado estos organismos y describe la aterradora facilidad con que pueden devorar a sus hospedadores e incluso controlar su conducta, como el siniestro Sacculina carcini, que se establece en un desafortunado cangrejo y devora todo menos aquello que su anfitrion necesita para llevarse comida a la boca, que sera consumida por el; o la criatura unicelular Toxoplasma gondii, que puede invadir el cerebro humano e influir en su conducta para asegurarse su supervivencia.Para Zimmer, la humanidad en si misma es una nueva clase de parasito que se aprovecha de todo el planeta. Por tanto, si vamos a alcanzar toda la sofisticacion que caracteriza a estas formas de vida, si vamos a fomentar el florecimiento de la vida en toda su diversidad tal como hacen ellos, debemos aprender como convive la naturaleza consigo misma, entender las leyes que rigen el extraño mundo de las criaturas mas peligrosas de la naturaleza.

In this unprecedented history of a scientific revolution, award-winning author and journalist Carl Zimmer tells the definitive story of the dawn of the age of the brain and modern consciousness. Told here for the first time, the dramatic tale of how the secrets of the brain were discovered in seventeenth-century England unfolds against a turbulent backdrop of civil war, the Great Fire of London, and plague. At the beginning of that chaotic century, no one knew how the brain worked or even what it looked like intact. But by the centurys close, even the most common conceptions and dominant philosophies had been completely overturned, supplanted by a radical new vision of man, God, and the universe. Presiding over the rise of this new scientific paradigm was the founder of modern neurology, Thomas Willis, a fascinating, sympathetic, even heroic figure at the center of an extraordinary group of scientists and philosophers known as the Oxford circle. Chronicled here in vivid detail are their groundbreaking revelations and the often gory experiments that first enshrined the brain as the physical seat of intelligence -- and the seat of the human soul. Soul Made Flesh conveys a contagious appreciation for the brain, its structure, and its many marvelous functions, and the implications for human identity, mind, and morality.

Charles Darwin desempeñó un papel crucial a la hora de convertir la herencia en una cuestión científica y, sin embargo, fracasó estrepitosamente a la hora de responderla. El nacimiento de la genética, a principios del siglo XX, parecio hacer precisamente eso. Poco a poco la gente tradujo sus antiguas nociones sobre la herencia a un lenguaje de genes. A medida que la tecnologia para el estudio de los genes se abarato, millones de personas pidieron pruebas geneticas para relacionarse con padres desaparecidos, con antepasados lejanos, con identidades etnicas... Pero, escribe Zimmer, "cada uno de nosotros es portador de una amalgama de fragmentos de ADN, cosidos a partir de algunos de nuestros muchos antepasados. Cada pieza tiene su propia ascendencia, recorriendo un camino diferente a traves de la historia de la humanidad. Un fragmento concreto puede ser a veces motivo de preocupacion, pero la mayor parte de nuestro ADN influye en lo que somos -nuestro aspecto, nuestra estatura, nuestras inclinaciones- de maneras inconcebiblemente sutiles". La herencia no se limita a los genes que pasan de padres a hijos. La herencia continua dentro de nuestro propio cuerpo, ya que una sola celula da lugar a trillones de celulas que conforman nuestro cuerpo. Decimos que heredamos los genes de nuestros antepasados -utilizando una palabra que antaño se referia a reinos y haciendas-, pero heredamos otras cosas que importan tanto o mas para nuestras vidas, desde los microbios hasta las tecnologias que utilizamos para hacer la vida mas comoda. Necesitamos una nueva definicion de lo que es la herencia y, a traves de la lucida exposicion y narracion de Carl Zimmer, este resonante tour de force nos la proporciona. Entrelazando investigaciones cientificas historicas y actuales, su propia experiencia con sus dos hijas y el tipo de reportaje original que se espera de uno de los mejores periodistas cientificos del mundo, Zimmer acaba por desentrañar los urgentes dilemas bioeticos que surgen de las nuevas tecnologias biomedicas, pero tambien las antiguas presunciones sobre quienes somos realmente y que podemos transmitir a las generaciones futuras.

Durante anos, os cientistas avisaram-nos de que uma pandemia era inevitavel. Tinham razo. E agora todos temos muito a aprender. Os virus dominam o planeta e transformam as nossas vidas. Estamos mais familiarizados com o virus da gripe, e agora com o responsavel pela COVID-19, mas os virus so responsaveis por muitas outras doencas. Est?o presentes na nossa vida ha tanto tempo que, neste momento, o genoma humano contem mais ADN de virus do que dos nossos proprios genes. Para onde quer que olhem, os cientistas descobrem novos virus: no solo, no oceano, e ate em grutas a quilometros de profundidade. Um Planeta de Virus desvenda o mundo escondido dos virus, incluindo o responsavel pela disseminaço da COVID-19. Apresenta as ultimas investigac?es sobre como os virus dominam a nossa vida e a nossa biosfera, como esto a produzir novas doencas, como podemos aproveita- los para nosso beneficio e como ir?o continuar a controlar o nosso destino durante seculos. Uma viagem fascinante a um mundo que todos devemos compreender melhor.

In 1946, a twenty-year-old medical school student called Joshua Lederberg decided to find out whether microbes make love. Lederberg was motivated not by a displaced libido, but by scientific ambition. At the age of seven, he had declared that he hoped to become like Einstein and to discover a few things in science.The few things Lederberg discovered would revolutionise modern science and earn him a Nobel Prize. He chose to observe the breeding habits of a certain bacterium called Escherichia coli, better known as E coli. His experiments used defective E coli strains lacking the essential molecules to reproduce by cloning which should, by rights, perish in the petri dish. But slowly, a few colonies of survivors began to spread accross the dishes. The only possible explanation for their survival was that they were a product of sex. Not only had Lederberg proved that bacteria have sex, he had also proved they have genes.Since then, a bacterium that was once nothing more than a humble resident of the human gut has become our best guide to what it means to be alive. Most of us might only know E coli for its lethal strain that causes food poisoning, but Zimmer uses E coli as a prism to understand what life is, what it was, and what it will become. We learn how E coli microbes talk to each other, how studies of their evolution represent the most powerful evidence in support of natural selection, and how they might just explain life on other planets...

Durante años los científicos nos han estado advirtiendo que una pandemia era casi inevitable. Ahora está aquí y el resto de nosotros tenemos mucho que aprender.Un planeta de virus presenta la investigacion mas reciente sobre como los virus dominan nuestras vidas y nuestra biosfera. Las explicaciones lucidas de Zimmer y sus fascinantes historias demuestran cuan profundamente estan entrelazados los humanos y los virus. Estos ayudaron a dar lugar a las primeras formas de vida, son responsables de muchas de nuestras enfermedades mas devastadoras y continuaran controlando nuestro destino durante siglos.Completamente legible y, a pesar de su honestidad acerca de las amenazas, tan tranquilizador como aterrador, es un fascinante recorrido por un mundo que todos necesitamos comprender mejor.

One of Smithsonian Magazines Ten Best Science Books of 2025The fascinating, untold story of the air we breathe, the hidden life it contains, and invisible dangers that can turn the world upside downEvery day we draw in two thousand gallons of airand thousands of living things. From the ground to the stratosphere, the air teems with invisible life. This last great biological frontier remains so mysterious that it took over two years for scientists to finally agree that the Covid pandemic was caused by an airborne virus.In Air-Borne, award-winning New York Times columnist and author Carl Zimmer leads us on an odyssey through the living atmosphere and through the history of its discovery. We travel to the tops of mountain glaciers, where Louis Pasteur caught germs from the air, and follow Amelia Earhart and Charles Lindbergh above the clouds, where they conducted groundbreaking experiments. We meet the long-forgotten pioneers of aerobiology including William and Mildred Wells, who tried for decades to warn the world about airborne infections, only to die in obscurity.Air-Borne chronicles the dark side of aerobiology with gripping accounts of how the United States and the Soviet Union clandestinely built arsenals of airborne biological weapons designed to spread anthrax, smallpox, and an array of other pathogens. Air-Borne also leaves readers looking at the world with new eyesas a place where the oceans and forests loft trillions of cells into the air, where microbes eat clouds, and where life soars thousands of miles on the wind.Weaving together gripping history with the latest reporting on Covid and other threats to global health, Air-Borne surprises us on every page as it reveals the hidden world of the air.

Profound, lyrical, and fascinating, Lifes Edge will give you a newfound appreciation for life itself. It is the work of a master science writer at the height of his skills. Ed Yong, author of An Immense WorldWe all assume we know what life is, but the more scientists learn about the living world from protocells to brains, from zygotes to pandemic viruses the harder they find it to locate the edges of life, where it begins and ends. What exactly does it mean to be alive? Is a virus alive? Is a foetus?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 cant 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 societys most charged conflicts whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.Lifes Edge is a fascinating investigation by one of the most celebrated science writers of our time. Whether he is handling pythons in Alabama or searching for hibernating bats in the Adirondacks, Zimmer revels in astounding examples of life at its most bizarre. He tries his own hand at evolving life in a test tube with unnerving results. Charting the obsession with Dr Frankensteins monster and how Coleridge came to believe the whole universe was alive, Zimmer leads us all the way into the labs and minds of researchers working on engineering life from the ground up.

Lifes Edge is an utterly fascinating investigation that no one but one of the most celebrated science writers of our generation could craft. Zimmer journeys through the strange experiments that have attempted to re-create life. Literally hundreds of definitions of what that should look like now exist, but none has yet emerged as an obvious winner. Lists of what living things have in common do not add up to a theory of life. Its never clear why some items on the list are essential and others not. Coronaviruses have altered the course of history, and yet many scientists maintain they are not alive. Chemists are creating droplets that can swarm, sense their environment, and multiply. Have they made life in the lab? Whether he is handling pythons in Alabama or searching for hibernating bats in the Adirondacks, Zimmer revels in astounding examples of life at its most bizarre. He tries his own hand at evolving life in a test tube with unnerving results. Charting the obsession with Dr. Frankensteins monster and how the world briefly believed radium was the source of all life, Zimmer leads us all the way into the labs and minds of researchers engineering life from scratch.

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...But, Zimmer writes, Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we areour appearance, our height, our penchantsin inconceivably subtle ways. Heredity isnt just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestorsusing a word that once referred to kingdoms and estatesbut we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity is and, through Carl Zimmers lucid exposition and storytelling, this resounding tour de force delivers it. Weaving historical and current scientific research, his own experience with his two daughters, and the kind of original reporting expected of one of the worlds best science journalists, Zimmer ultimately unpacks urgent bioethical quandaries arising from new biomedical technologies, but also long-standing presumptions about who we really are and what we can pass on to future generations.

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. Asi nos descubre no solo la forma de vida mas exitosa del planeta, sino aquella que da forma a los ecosistemas y es el motor de la evolucion. Zimmer nos muestra, pues, cuanto han evolucionado estos bichos, y relata la aterradora facilidad con que pueden devorar a quien los hospeda, e incluso controlar su conducta. Es el caso del siniestro Sacculina carcini, que lo devora todo del infortunado cangrejo que lo lleve dentro, salvo aquello que al cangrejo le haga falta para alimentarse. Porque el alimento acabara siendo para el parasito. O pensemos en la criatura unicelular Toxoplasma gondii, que puede invadir el cerebro humano e influir en su conducta para asegurarse la propia supervivencia."Zimmer deshecha la ilusion de un mundo sin parasitos; mas practico le parece aprender a convivir con ellos y a tenerlos a raya (). Y si, despues de su argumentacion, el lector sigue considerando a esos seres una asquerosidad sin paliativos, el autor le invita a preguntarse: ¿no seremos nosotros el pinaculo de la jerarquia parasitaria, la especie mas ducha en succionar la vitalidad de nuestra anfitriona, la Tierra?"
