For billions of years, microbes have produced and consumed greenhouse gases that regulate global temperature and in turn other aspects of our climate. The balance of these gases maintains Earth's habitability. Methane, a greenhouse gas produced only by microbes, may have kept Earth out of a deep freeze billions of years ago. Likewise, variations in carbon dioxide, another greenhouse gas released by microbes and other organisms, help to explain the comings and goings of ice ages over the last million years. Now we face a human-made climate crisis with drastic consequences.

Long Litt Woon met Eiolf a month after arriving in Norway from Malaysia as an exchange student. They fell in love, married, and settled into domestic bliss. Then Eiolf’s unexpected death at 54 left Woon struggling to imagine a life without the man who had been her partner and anchor for 32 years. Adrift in grief, she signed up for a beginner’s course on mushrooming - a course the two of them had planned to take together - and found, to her surprise, that the pursuit of mushrooms rekindled her zest for life.

More than anything else, this is a book about love. In this deeply moving account, you will hear about Rambo, a sheep who informs the staff when another animal is in trouble; and Paulie, a former cockfighting rooster who eats lunch with humans; Dino, an old toothless pony who survived a fire; and many more. Alongside these horses, roosters, pigs, sheep, rabbits, cows, and other animals is a staff of loving humans for whom every animal life, even that of a frog rushed to the vet for emergency surgery, has merit.

George Soper (1870-1948) was a sanitation engineer who tracked down Mary Mallon, or Typhoid Mary (1869-1938), a cook who was an asymptomatic carrier of typhoid responsible for at least 54 cases with four deaths in nine different epidemics. Soper was called in when a landlord in Long Island struggled to trace the source of an outbreak in 1906. Soper’s every attempt to reason with Mary was met by denial and a refusal to cooperate. She was arrested by the New York Health Department and placed in a detention hospital on March 19, 1907.

Being overweight is not just the result of too many cheeseburgers or not enough exercise. According to leading-edge science, there are silent saboteurs in our daily lives that contribute greatly to our obesity epidemic: obesogens. These weight-inducing offenders, most of which are chemicals, disrupt our hormonal systems, alter how we create and store fat, and change how we respond to dietary choices. Because they are largely unregulated, obesogens lurk all around us - in food, furniture, plastic products such as water bottles and food containers, and other surprising exposure points.

Have you been worrying that your memory may be slipping? Or are you envious of your classmate’s apparent ability to memorize large amounts of information with ease? Perhaps you are heading towards the “golden years” and you just want to make sure you keep your memory sharp. Or you are about to start school after a long sabbatical and you want to be sure your study skills are up to par.

Suddenly, research findings require a paradigm shift in our view of the microbial world. The Human Microbiome Project at the National Institutes of Health is well under way, and unprecedented scientific technology now allows the censusing of trillions of microbes inside and on our bodies as well as in the places where we live, work, and play. This intriguing, up-to-the-minute book for scientists and nonscientists alike explains what researchers are discovering about the microbe world and what the implications are for modern science and medicine.

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.

What is life? Many scientists believe life can be reduced to ‘mechanistic’ factors, such as genes and information codes. Yet there is a growing army of scientists, philosophers and artists who reject this view. The gene metaphor is not only too simplistic but deeply misleading. If there is a way to reduce life to a single principle, that principle must acknowledge the creativity of life, turning genetic determinism on its head.

By 2030, experts predict two-thirds of people living on this planet will not have enough water, a situation expected to result in the deaths of millions and an unprecedented rise in military conflicts. Can we as individuals hope to reverse these dire predictions? Award-winning author and water activist Florencia Ramirez believes we can if our conservation efforts focus on the 70 percent of freshwater flowing to the fields and ranches that grow our food. Eat Less Water takes the listener on a journey to meet America's food producers growing food with less water.

In Sex Robots and Vegan Meat, award-winning journalist and documentary maker Jenny Kleeman takes us on a journey into the world of the people who are changing what it means to be human. Focusing on the central pillars of the human experience - birth, food, sex, and death - Kleeman examines the people who are driving some truly amazing, and perhaps worrying, innovations.

Why is it impossible to spin your right foot clockwise while you draw a six with your right hand? Can you extract DNA from a strawberry daiquiri? Would you make love like a praying mantis? Should you book a holiday on Earth 2.0? The Element in the Room will take you on a rib-tickling, experiment-fuelled adventure to explain everyday science that is staring you in the face. If you are sci-curious, pi-curious or just the-end-is-nigh-curious then this is the book for you.

Arsuaga en su máximo esplendor. El primer libro sobre la evolución de la anatomía humana, y que une ciencia y arte. 4.ª edición. Más de 40.000 lectores. En el museo del Prado, un científico recorre con la vista la escultura del Diadúmeno de Policleto; en su anatomía puede leer una historia evolutiva de siete millones de años. En la sala contigua hay otra algo más tardía que muestra la figura desnuda de la Venus del delfín, el canon helenístico de la belleza femenina. El científico aprecia las diferencias entre ambos y se pregunta por su significado.

Most of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender's Blue? Or the St. Francis' Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures - some numbering no more than what can be held in one hand.

A group of traders huddles around a pile of dried shark fins on a gleaming white floor in Hong Kong. A Papua New Guinean elder shoves off in his hand-carved canoe, ready to summon a shark with ancient magic. A scientist finds a rare shark in Indonesia and forges a deal with villagers so it and other species can survive. In this eye-opening adventure that spans the globe, Juliet Eilperin investigates the fascinating ways different individuals and cultures relate to the ocean’s top predator. Along the way, she reminds us why, after millions of years, sharks remain among nature’s most awe-inspiring creatures.

I will show you how to find and harvest Chaga mushrooms and how to properly consume Chaga. We’ll also provide you with some recipes that help you improve your health and keep it running smoothly for years to come.

Written in a brilliantly engaging style by biologist Jules Howard, this fascinating and highly engaging work covers the how and why of sex on Earth, in all its diversity. From sperm wars to cuckoldry, hermaphrodites and virgin births, spent males, racy harems, clitoral births, hips, breasts and birdsong, penis-percussion, and those riskiest and most elusive of all traits, monogamy and true love, all this and more is discussed in Sex on Earth, as Jules takes us on a voyage of discovery of the ins and outs of animal reproduction.

Life is the most extraordinary phenomenon in the known universe; but how does it work? Even in this age of cloning and synthetic biology, the remarkable truth remains: nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we missing a vital ingredient in its creation? Like Richard Dawkins' The Selfish Gene, which provided a new perspective on how evolution works, Life on the Edge alters our understanding of life's dynamics.

Para cada célula humana em nosso organismo, há outras nove impostoras, pegando carona. Você não é formado apenas de carne e osso, sangue e músculo, mas também de bactérias e fungos. Não é um indivíduo, mas uma colônia–um ecossistema. Somos apenas 10% humanos. Até pouco tempo atrás, os micróbios eram vistos como invasores, inimigos, parasitas. Estávamos decididos a exterminá-los. Mas a ciência vem revelando uma história bem diferente: os micro-organismos comandam nosso corpo e evoluíram numa relação de estreita simbiose com os humanos–e é impossível ser saudável sem eles.

Since the birth of civilization, human beings have manipulated other life-forms. We have selectively bred plants and animals for thousands of years to maximize agricultural production and cater to our tastes in pets. The observation of the creation of artificial animal and plant variants was a key stimulant for Charles Darwin's theory of evolution. The ability to directly engineer the genomes of organisms first became possible in the 1970s, when the gene for human insulin was introduced into bacteria.
