The possibility of life elsewhere in the cosmos is one of the most profound subjects that human beings can ponder. Astrophysicist Andrew May gives an expert overview of our current state of knowledge, looking at how life started on Earth, the tell-tale ‘signatures’ it produces and how such signatures might be detected elsewhere in the solar system or on the many ‘exoplanets’ now being discovered by the Kepler and TESS missions.

First there was the genetic revolution—the discovery that physical structures in the cell, including DNA and RNA, shape every organism. Now, says evolutionary biologist Richard Sternberg, we are overdue for another and more profound revolution. Recent findings reveal that genetic and even epigenetic sources alone cannot account for the rich dynamism of life—not even close. Some other informational source is required.

In "Icarus; or, The Future of Science," Bertrand Russell explores the potential consequences of scientific advancement, drawing parallels between the myth of Icarus and the development of technology. He argues that while science can lead to progress, it also poses risks, particularly regarding power and societal structures. Russell suggests that scientific advancements, especially in the physical sciences, can increase power, lead to industrialism and war, and necessitate large-scale organization, which could potentially be used for oppressive purposes.

In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy.

The Earth teems with life: in its oceans, forests, skies, and cities. Yet there's a black hole at the heart of biology. We do not know why complex life is the way it is, or, for that matter, how life first began. In The Vital Question, award-winning author and biochemist Nick Lane radically reframes evolutionary history, putting forward a solution to conundrums that have puzzled generations of scientists.

It seems like every time a new mother turns on her computer, radio, or television she is greeted with news of yet another scientific study about infancy. Ignoring good information isn't the right course, but just how does one tell the difference between solid studies, preliminary results, and snake oil? In this friendly guide through the science of infancy, Science of Mom blogger and PhD scientist Alice Callahan explains how nonscientist mothers can learn the difference between hype and evidence.

The landscape of cancer treatment and prevention is a vastly different place than it was even a decade ago. Thanks to a relatively new focus on molecular medicine, researchers are gaining a deeper understanding of the mechanisms involved in the disease, poising them on the brink of huge breakthroughs. What Science Knows About Cancer reports from the front lines of the war on cancer with a clear and scientifically precise - yet thoroughly accessible - guide to how the disease develops, thrives, and can potentially be conquered.

Epidemiologist Steffanie Strathdee and her husband, psychologist Tom Patterson, were vacationing in Egypt when Tom came down with a stomach bug. What at first seemed like a case of food poisoning quickly turned critical, and by the time Tom had been transferred via emergency medevac to the world-class medical center at UC San Diego, where both he and Steffanie worked, blood work revealed why modern medicine was failing: Tom was fighting one of the most dangerous, antibiotic-resistant bacteria in the world.

A journey through life, the universe and everything. From what actually happened in the big bang to the accidental discovery of Post-it notes, science is packed with surprising discoveries. Did you know, for instance, that if you were to get too close to a black hole it would suck you up like a noodle (it's called spaghettification), why your keyboard is laid out in QWERTY (it's not to make it easier to type) or whether the invention of the wheel was less important to civilisation than the bag (think about it)? New Scientist does.

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.

The existence of free will - our ability to choose between one course of action and another, to determine our own destiny - is a foundation stone of Western society, dictating our notions of fairness and justice, punishment and reward, our very identity as individuals and humans. But as world-renowned scientist Robert Sapolsky shows, there is not a shred of evidence to suggest that free will exists, even while everything in our biology leads us to believe that it does.

We may believe that we are the masters of our fates, but in reality, we are at the mercy of hundreds of trillions of single-celled organisms that exert control over every aspect of how our minds and bodies function. These are the diverse species of microbes that work together synergistically to communicate with each other and with every system in our bodies. You are your microbiome’s home, and it wants to take care of you, but first you have to protect it. In Gut Check, Dr. Steven Gundry reveals the emerging science proving that Hippocrates was right—all disease begins in the gut.

Susan Casey is our premiere chronicler of the aquatic world. For The Underworld she traversed the globe, joining scientists and explorers on dives to the deepest places on the planet, interviewing the marine geologists, marine biologists, and oceanographers who are searching for knowledge in this vast unseen realm. She takes us on a fascinating journey through the history of deep-sea exploration, from the myths and legends of the ancient world to storied shipwrecks we can now reach on the bottom.

The European eel, Anguilla anguilla, is one of the strangest creatures nature ever created. Remarkably little is known about the eel, even today. What we do know is that it’s born as a tiny willow-leaf-shaped larva in the Sargasso Sea, travels on the ocean currents toward the coasts of Europe - a journey of about 4,000 miles that takes at least two years. Upon arrival, it transforms itself into a glass eel and then into a yellow eel before it wanders up into fresh water.

Part mind-bending medical mystery—part cutting-edge science—Hidden Guests uncovers the astonishing phenomenon of microchimerism: the presence of foreign cells inside our own bodies. The incredible story of how those cells got there—and what they do once they arrive—might change everything we know about the immune system, lineage, and identity.

Humanities Breakthrough on Longevity and Immortality.

All of life is profoundly shaped by the daily, monthly, and yearly cycles of our planet, and all creatures have internal timekeeping systems that rely on cues from the surrounding environment. With modern technology, we are changing our environments—and by proxy, the ecosystems around us—to override these innate rhythms of life. But at what cost? Life in Sync reveals how Earth’s rotations shape our biology, what human sleep cycles looked like before the advent of artificial light, and why technology can’t free us from the constraints of our circadian clocks.

Carlos López-Otín, prominente figura en el ámbito de la bioquímica y la biología molecular y autor de la exitosa Trilogía de la vida, nos propone un nuevo enfoque científico centrado en la medicina de la salud, y nos desvela los secretos para fomentarla y lograr el necesario equilibrio físico y mental.

We all know the importance of mothers. They are typically as paramount in the wild as they are in human relationships. But what about fathers? In most mammals, fathers have little to no involvement in raising their offspring—and sometimes even kill the offspring sired by other fathers. How, then, can we explain modern fathers having the capacity to be highly engaged parents? In Father Nature, James Rilling explores how humans have evolved to endow modern fathers with this potential and considers why this capacity evolved in humans.
