Showing results for "lifes a" in Biology

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

From the battlefields of Homer's Iliad, where muscles first entered world literature, to the Victorian-era gymnasiums where women built strength and muscle by lifting heavy weights, to a retirement home in Boston, where a young doctor discovered that training at high intensity can produce the same relative gains for frail ninety-year-olds as for thirty-year-olds, Stronger places the science and significance of our muscles in an astonishing new light.

In LIFE AS NO ONE KNOWS IT, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is. This is an urgent issue for efforts to make life from scratch in laboratories here on Earth and missions searching for life on other planets. Walker proposes a new paradigm for understanding what physics encompasses and what we recognize as life.

The world is in crisis! What is the solution? Ultimately, we have to find the redeeming, and thus transforming, understanding of our psychologically troubled human condition. And it is precisely that dreamed-of insight, and its now desperately needed transformation of our lives, that Australian biologist Jeremy Griffith presents in this book.

Sir Paul Nurse is one of Britain's greatest living scientists. Here he invites listeners on a journey of discovery of biology's five great building blocks including The Cell, The Gene, Evolution by Natural Selection, Life as Chemistry, Life as Information and then an inspiring piece on how we can change the world with this knowledge. Accessible and easy to listen to, Paul's engaging, personal tone will make listeners light up with excitement as they learn how all living beings are connected.

Biology is undergoing a quiet but profound transformation. Several aspects of the standard picture of how life works—the idea of the genome as a blueprint, of genes as instructions for building an organism, of proteins as precisely tailored molecular machines, of cells as entities with fixed identities, and more—have been exposed as incomplete, misleading, or wrong. In How Life Works, Philip Ball explores the new biology, revealing life to be a far richer, more ingenious affair than we had guessed.

What is it that helps both scorpions and cyclists to survive? What do raw eggs and gyroscopes have in common? And why does it matter? In an age of string theory, fluid dynamics and biophysics, it can seem as if the science of our world is for only specialists and academics. Not so, insists Helen Czerski - and in this sparkling new audiobook she explores the patterns and connections that illustrate the grandest theories in the smallest everyday objects and experiences.

Have you ever wondered what makes every heartbeat, every thought, and every movement possible? Meet your mitochondria—tiny but mighty organelles that are the true engines of life. These organelles are popularly known as the “powerhouses of the cell,” but new research shows that the mitochondria do more than just convert food into energy—they’re orchestrators of critical functions that keep you healthy and alive.

Trees clean air and water; hoverflies and bees pollinate our crops; the kingfisher inspired the construction of high-speed trains. In Tapestries of Life, best-selling author Anne Sverdrup-Thygeson explains how closely we are all connected with the natural world, highlighting our indelible link with nature’s finely knit system and our everyday lives.

Every Living Thing centres on the rivalry pledged between two scientists, Linnaeus and Buffon, who, from 1743 to 1778 raced each other to complete an inventory of all life on Earth. Their focus was on scientific immortality and the core conception of our relationship to the natural world. Their catalogues were starkly different and showed a divergence of opinion on the creation of nature and humanity. Buffon advocating for a natural system of classification, while Linnaeus was dedicated to naming and classifying objects of nature.

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

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?

The notion of a living world is one of humanity’s oldest beliefs. Though once scorned by many scientists, the concept of Earth as a vast interconnected living system has gained acceptance in recent decades. Life not only adapts to its surroundings – it also shapes them in dramatic and enduring ways. Over billions of years, life transformed a lump of orbiting rock into our cosmic oasis, breathing oxygen into the atmosphere, concocting the modern oceans, and turning rock into fertile soil. Life is intertwined with Earth’s capacity to regulate its climate and maintain balance.

Spontaneous generation of living organisms - life arising without progenitor or seed - was a common belief in the time of Aristotle. Over the next 2,000 years, support for spontaneous generation slowly retreated to its final stronghold: spontaneous formation of the first living organism.

Charles Darwin’s theories, first published more than 150 years ago, still set the paradigm of how we understand the evolution of life--but scientific advances of recent decades have radically altered that. Now two pioneering scientists draw on their years of experience in paleontology, biology, chemistry, and astrobiology to deliver an eye-opening narrative using a generation’s worth of insights culled from new research.

While cells are commonly considered the building block of living things, it is actually the communication between cells that brings us to life, controlling our bodies and brains, determining whether we are healthy or sick, and directly influencing how we think, feel, and behave. In The Secret Language of Cells, doctor and neuroscientist Jon Lieff lets us listen in on these conversations, and reveals their significance for everything from mental health to cancer.

In this classic work that continues to inspire its many fans, James Lovelock deftly explains his idea that life on Earth functions as a single organism. Written for the non-scientist, Gaia is a journey through time and space in search of evidence with which to support a new and radically different model of our planet. In contrast to conventional belief that living matter is passive in the face of threats to its existence, the book explores the hypothesis that the Earth's living matter - air, ocean, and land surfaces - forms a complex system that has the capacity to keep the Earth a fit place for life.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.
