Not too long ago, there was no coming back from death. But now, with revolutionary medical advances, death has become just another serious complication. As a young medical student, Dr. David Casarett was inspired by the story of a two-year-old girl named Michelle Funk. Michelle fell into a creek and was underwater for over an hour. When she was found she wasn't breathing, and her pupils were fixed and dilated. That drowning should have been fatal. But after three hours of persistent work, a team of doctors and nurses was able to bring her back.

Are we alone in the universe—or is life a cosmic inevitability? Life in the Cosmic Context goes beyond the conventional search for extraterrestrial biology, asking deeper questions about the very nature of life and our place in an immense, evolving cosmos. In this groundbreaking work, astrobiology becomes more than the science of life beyond Earth; it is a philosophical lens for reimagining what life itself can be. From the origins of life on Earth to the potential for entirely different biochemistries elsewhere, this book challenges listeners to rethink what is possible.

We know much about our history from bones and DNA, but these studies do not tell us about the characteristics that are not preserved in the fossil record―the fleshy parts and behaviors. Looking Down the Tree applies evolutionary principles to understand the history of our species and the pressures of natural selection which led to our unique appearance and behaviors. Cruzan draws upon evidence from fossils, genomics, phylogenetics, coalescence theory.

Microfluidics is the field of science that studies fluids constrained to spaces that are smaller than one millimeter wide, and by extension, the engineering field which builds devices that exploit the unique properties of fluids at these scales. Author Albert Folch explores this micro science which has inspired engineers to build devices such as engines, spray cans, ballpoint pens, inkjet and 3D printers, pregnancy and Covid tests, glucometers, asthma nebulizers, kidney dialysis machines, and DNA analyzers.

En 2016, se publicaron los resultados de un experimento sorprendente. A un grupo de ratones les cambiaron todas sus bacterias intestinales por otras de personas con depresión. Al cabo de unos días, los ratones se deprimieron. La depresión se puede trasplantar… en ratones. Estudios como este demuestran la estrecha relación entre nuestros microbios (la microbiota) y nuestras células. Cuando ese equilibrio se altera y disminuyen el número y diversidad de los microorganismos, tenemos un problema.

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.

A comprehensive guide to everything one needs to know about the male reproductive system.

Сначала Земля представляла собой негостеприимное чужеродное место: на планету непрерывно обрушивались потоки химических веществ, она была покрыта бурлящими океанами, а ландшафт формировали непрекращающиеся извержения вулканов. Посреди этого буйства стихий и катастроф и началась жизнь. Похожие на мыльные пузырьки первые клетки с дерзкой отвагой бросили вызов безжизненному миру.

La consciencia humana es lo que nos hace ser unos seres vivos excepcionales. Gracias a ella sabemos que existimos, tenemos idea de que hay un pasado y un futuro. Permite que creamos en cosas que no vemos y hasta nos dota de esperanza para pensar en una vida más allá de la muerte. Este libro indaga en lo que entendemos por consciencia desde un punto de vista científico, filosófico y cultural. ¿Dónde reside nuestra consciencia? ¿Cómo afecta a cada ser humano? Estas y muchas preguntas más se abordan en esta obra.

Throughout the ages, human beings have had a profound fascination with the natural world. It has influenced all aspects of our civilisation, from science and religion to music, art, literature and film. These 12 episodes, taken from Radio 4's epic series Natural Histories, find presenter Brett Westwood exploring two major groups of animals - fish, who have lived on Earth for over 450 million years, and invertebrates, who make up 97 percent of all species worldwide - to find out how our perception and representation of them has changed over time.

This book comes from two authors with scientific backgrounds. It recognizes the huge advances made through science and their beneficial impact on society. However, it also expresses concern that the essentially tentative nature of scientific conclusions is being replaced by a growing tendency to accord to science the last word on a range of subjects.

Von einer, die auszog, die Schildkröten zu retten. Elegant gleiten sie durchs Wasser, legen Tausende Kilometer zurück und finden selbst Jahre später noch den Weg an die Strände ihrer Geburt. Meeresschildkröten sind faszinierende Urzeitwesen, und Christine Figgener macht sich seit Langem für ihre Erforschung und ihren Schutz stark. Expertenwissen einer engagierten Meeresbiologin. Nun nimmt sie uns mit auf eine Reise durch das Leben dieser Tiere und durch ihr eigenes.

The egg is a paradox―both alive and not alive―and a symbol as old as culture itself. In this wide-ranging and delightful journey through its natural and cultural history, Lizzie Stark explores the egg’s deep meanings, innumerable uses, and metabolic importance through a dozen dazzling specimens. Egg is playful, informative, and guarantees that you’ll never take this delicate ovoid for granted again.

Als im späten 16. Jahrhundert der englische Universalgelehrte Robert Hooke und der holländische Tuchhändler Antonie van Leeuwenhoek durch ihre handgefertigten Mikroskope blickten, sahen sie etwas, was der Biologie und der Medizin ein radikal neues Konzept hinzufügte und beide Wissenschaften für immer veränderte: Komplexe lebende Organismen bestehen aus winzigen, in sich geschlossenen und sich selbst regulierenden Einheiten. Unsere Organe, unsere Physiologie, unser Selbst – Herz, Blut, Gehirn – sind aus diesen kleinen Teilen aufgebaut: den Zellen.

Tap into an ancient cellular survival program to optimize health and longevity. Understanding Life will help curious people understand how life might have originated, how metabolism evolved, and what the implications are for health, aging, and disease.

For as long as humans have existed, insects have been our constant companions. Yet we hardly know them, not even the ones we’re closest to: those that eat our food, share our beds, and live in our homes. Organizing his book alphabetically, Hugh Raffles weaves together brief vignettes, meditations, and extended essays, taking the listener on a mesmerizing exploration of history and science, anthropology and travel, economics, philosophy, and popular culture.

La humanidad ha estado siempre obsesionada con la idea de la inmortalidad y los secretos de la longevidad siguen siendo un misterio, hasta que la ciencia ha empezado a observar la naturaleza en busca de respuestas. Este libro nos cuenta por qué y cómo envejecemos, qué podemos aprender de la naturaleza para vivir más años y qué estrategias seguir en nuestra vida para mantener un buen estado físico hasta la vejez.

Un libro imprescindible en la línea de Sapiens, de Yuval Noah Harari. Un ensayo que mezcla las humanidades, con la filosofía moral y la ciencia. Una investigación que aporta una visión amplia y humana de lo que significa ser humano. Los humanos son los animales más curiosos, emocionales, imaginativos, agresivos y desconcertantes del planeta. Pero, ¿nos conocemos realmente bien a nosotros mismos?

SARS­CoV­2 hält seit über zwei Jahren die Welt in Atem. Doch wo liegt der Ursprung des Virus und wie genau ist es entstanden? Wie ein Krimi ­nal kommissar hat sich der erfahrene Molekular­biologe Günter Theißen auf Spurensuche begeben und seit Anbeginn der Pandemie alle verfügbaren Fakten zusammenge tragen. Schon bald musste er jedoch feststellen, dass sich die Mehrzahl der Fachleute und ein Großteil der Medien auf eine rein natürliche Entstehung des Virus festgelegt haben—ohne hieb­ und stichfeste Beweise! Warum besteht so wenig Interesse daran, die Wahrheit zu erfahren?
