Ignác Semmelweis is remembered for the now-commonplace notion that doctors must wash their hands before examining patients. In mid-19th century Vienna, however, this was a subversive idea. With deaths from childbed fever exploding, Semmelweis discovered that doctors themselves were spreading the disease. While his simple reforms worked immediately - childbed fever in Vienna all but disappeared - they brought down upon Semmelweis the wrath of the establishment, and led to his tragic end.

Bacteria form a fundamental branch of life. They are the oldest forms of life and the most prolific of all living organisms, inhabiting every part of the Earth's surface, its ocean depths, and even such inhospitable places as boiling hot springs. In this Very Short Introduction, bacteriologist Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease.

For most of modern medicine, cancer drugs have been developed the same way: by designing molecules to treat diseased cells. Chimeric Antigen Receptor T cell therapy, commonly referred to as CAR T therapy, is a revolutionary cell-based immunotherapy treatment that breaks this mold. A patient's cells are transformed through genetic engineering and reinfused into the bloodstream, allowing the cells to identify and eliminate their targets better than they naturally can. For many patients, this translates to a long-term remission or cure. As an early pioneer in cell therapies using dendritic ...

Consciousness is our gateway to experience: it enables us to recognize Van Gogh’s starry skies, be enraptured by Beethoven’s Fifth, and stand in awe of a snowcapped mountain. Yet consciousness is subjective, personal, and famously difficult to examine: philosophers have for centuries declared this mental entity so mysterious as to be impenetrable to science. In The Ravenous Brain, neuroscientist Daniel Bor departs sharply from this historical view, and proposes a new model for how consciousness works.

What is life? Humans have been asking this question for thousands of years. But as technology has advanced and our understanding of biology has deepened, the answer has evolved. For decades, scientists have been exploring the limits of nature by modifying and manipulating DNA, cells, and whole organisms to create new ones that could never have previously existed on their own.

From beneficial yeasts that aid digestion to toxic molds that cause disease, we are constantly navigating a world filled with fungi. Molds, Mushrooms, and Medicines explores the amazing ways fungi interact with our bodies, showing how our health and well-being depend on an immense ecosystem of yeasts and molds inside and all around us.

Well-meaning physicians, parents, and even scientists today often spread misinformation about what biology can and can't tell us about our bodies, minds, and identities. In this accessible, myth-busting book, geneticist Shoumita Dasgupta draws on the latest science to correct common misconceptions about how much of our social identities are actually based in genetics.

In Tree Thieves, Lyndsie Bourgon takes us deep into the underbelly of the illegal timber market. As she traces three timber poaching cases, she introduces us to tree poachers, law enforcement, forensic wood specialists, the enigmatic residents of former logging communities, environmental activists, international timber cartels, and indigenous communities along the way.

Professor Rose Anne Kenny has thirty-five years of experience at the forefront of aging medicine. In Age Proof, she draws on her own pioneering research and the latest evidence to demystify why we age and shows us that 80% of our aging biology is within our control: we can not only live longer lives but become happier and healthier in our later years. Effortlessly distilling scientific theory into practical advice that we can apply to our lives, Professor Kenny examines the impact that food, genetics, friendships, purpose, sex, exercise, and laughter have on how our cells age.

In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarizing what we know about all of the major and minor extinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions.

In order to understand the future of antibiotics, we need to understand their past. Dangerous Miracle tells the story of antibiotics: weaving the grand arc of their evolution over millions of years with a history of the past century. Antibiotic resistance shows how easily bacteria have been able to undo human progress. If we want antibiotics to have a future, we need to prepare to adapt accordingly. And fast.

There is a fundamental connection between the brain, the gut, the microbiome, and the thyroid: if any one part of this "whole brain" system is malfunctioning, it will impact the others. Taking care of your whole brain is the basis of Dr. Kellman's revolutionary approach to curing depression and other mood problems - without medication.

In The Equations of Life, biologist Charles S. Cockell makes the forceful argument that the laws of physics narrowly constrain how life can evolve, making evolution's outcomes predictable. If we were to find something very much like a lady bug eating something very much like an aphid on a distant planet, we shouldn't be surprised. The forms of life are guided by a limited set of rules, and, as a result, there is a narrow set of solutions to the challenges of existence.

For much of recorded history, people considered the heart to be the most important organ in the body. In cultures around the world, the heart—not the brain—was believed to be the location of intelligence, memory, emotion, and the soul. Over time, views on the purpose of the heart have transformed. Modern medicine and science dismissed what was once the king of the organs as a mere blood pump subservient to the brain, yet the heart remains a potent symbol of love and health and an important part of our cultural iconography.

The question of how and why organisms age has teased scientists for centuries. There are myriad competing theories, from the idea that ageing is a simple wear and tear process, like the rusting of a car, to the belief that ageing and death are genetically programmed and controlled. In fact, there is no clearly defined limit to life and no single, predictable program playing itself out: different things are happening within and between tissues, and each system or organ accumulates damage at its own pace, according to the kind of insults imposed on it by daily living.

The Revolutionary Phenotype is a science book that brings us four billion years into the past, when the first living molecules showed up on Planet Earth. Unlike what was previously thought, we learn that DNA-based life did not emerge from random events in a primordial soup. Indeed, the first molecules of DNA were fabricated by a previous life form.

Guess what: Bees are incredible. Extreme bee enthusiast and bestselling author Matt Kracht is here to set the record straight with this helpful guidebook to all things bees.

Horses have a story to tell - one of resilience, sociability, and intelligence and of partnership with human beings. In The Horse, journalist and equestrienne Wendy Williams brings that story brilliantly to life. Williams chronicles the 56-million-year journey of horses as she visits with experts around the world, exploring what our biological affinities and differences can tell us about the bond between horses and humans and what our longtime companions might think and feel.

No eres solo humano, eres un universo de bacterias con más poder sobre ti del que crees…¡úsalo a tu favor! "El camino hacia la salud microbiana no es tarea sencilla. Sin embargo, con valentía, constancia, determinación y el apoyo de profesionales capacitados, lograrás que sea posible". ¿Sabías que en nuestro cuerpo existen más de 38 billones de bacterias? ¿Y que si las agrupamos conforman al menos mil especies distintas? Están en todas partes: en los intes¬tinos, en la boca, en el aparato reproductor, en toda nuestra piel.

Geoffrey West's research centres on a quest to find unifying principles and patterns connecting everything, from cells and ecosystems to cities, social networks and businesses. Scale addresses big, urgent questions about global sustainability, population explosion, urbanization, ageing, cancer, human life spans and the increasing pace of life but also encourages us to question the world around us.
