How did life begin? Why are we here? These are some of the most profound questions we can ask. For almost a century, a small band of eccentric scientists has struggled to answer these questions and explain one of the greatest mysteries of all: how and why life began on Earth. There are many different proposals and each idea has attracted passionate believers who promote it with an almost religious fervour, as well as detractors who reject it with equal passion.

The Very Best of Charles Darwin comprises On the Origin of Species and The Voyage of the Beagle. The first introduced the theory that populations evolve over the course of generations through a process of natural selection. The evidence was gathered on the Beagle expedition in the 1830s, recounted in The Voyage of the Beagle, which is both a travel memoir and a scientific field journal of anthropological, biological, and geological interest.

Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior - who we are and how we got to be here, our psychology, our cultures - and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution has been, and continues to be, regarded with suspicion by many.

International sex researcher, neuroscientist, and columnist Debra Soh debunks popular gender myths in this scientific examination of the many facets of gender identity that “is not only eminently reasonable and beautifully-written, it is brave and vital” (Ben Shapiro, number-one New York Times best-selling author).

If you think sexism thrives only on Wall Street or Hollywood, you haven’t visited a lab, a science department, a research foundation, or a biotech firm. Rita Colwell is one of the top scientists in America: the groundbreaking microbiologist who discovered how cholera survives between epidemics and the former head of the National Science Foundation. But when she first applied for a graduate fellowship in bacteriology, she was told, “We don’t waste fellowships on women.” A lack of support from some male superiors would lead her to change her area of study six times.

Did NASA really spend millions creating a pen that would write in space? Is chocolate poisonous to dogs? Does stress cause gray hair? These questions are a sample of the urban lore investigated in this audiobook, Fact or Fiction: Science Tackles 58 Popular Myths. Drawing from Scientific American’s “Fact or Fiction” and “Strange But True” columns, we’ve selected 58 of the most surprising, fascinating, useful, and just plain wacky topics confronted by our writers over the years.

Our sense of smell - or olfaction as it is technically known - is our most enigmatic sense. It can conjure up memories, taking us back to very specific places and emotions, whilst powerful smells can induce strong feelings of hunger or nausea. In the animal kingdom smell can be used to find food, a mate, or a home; to sense danger; and to send and receive complex messages with other members of a species. Yet despite its fundamental importance in our mental life and in the existence of all animals, our scientific understanding of how smell works is limited.

When writer Rebecca Giggs encountered a humpback whale stranded on her local beachfront in Australia, she began to wonder how the lives of whales reflect the condition of our oceans. Fathoms: The World in the Whale is “a work of bright and careful genius” (Robert Moor, New York Times best-selling author of On Trails), one that blends natural history, philosophy, and science to explore: How do whales experience ecological change? How has whale culture been both understood and changed by human technology?

In this Very Short Introduction audiobook, marine biologist Philip Mladenov provides an accessible and up-to-date overview of marine biology, offering a tour of marine life and marine processes that ranges from the unimaginably abundant microscopic organisms that drive the oceans' food web to the apex predators that we exploit for food; from polar ocean ecosystems to tropical coral reefs; and from the luxurious kelp beds of the coastal ocean to deep-ocean hydrothermal vents where life exists without the energy of the sun.

Keeping skin healthy is a booming industry, and yet it seems like almost no one agrees on what actually works. What one person says is vital another says is toxic. We have not cured acne or eczema, allergies keep getting worse, and autoimmune conditions are becoming increasingly common. In Clean, doctor and journalist James Hamblin explores how we got here, examining the science and culture of how we care for our skin today.

Popular science master Brian Clegg’s new book is an entertaining tour through the science of what makes you you. From the atomic level, through life and energy to genetics and personality, it explores how the billions of particles which make up you - your DNA, your skin, your memories - have come to be.

Sharks are ruthlessly efficient predators, the apex of 450 million years of evolution. They are older than trees, have survived five extinction events and are essential to maintaining balanced ocean ecosystems, but how much do we really know about their lives? The first book to reveal the hidden world of sharks, Emperors of the Deep draws upon the latest scientific research to examine four species in detail - mako, tiger, hammerhead and great white - as never before.

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.

In Regenesis, George Church and science writer Ed Regis explore the possibilities of the emerging field of synthetic biology. Synthetic biology, in which living organisms are selectively altered by modifying substantial portions of their genomes, allows for the creation of entirely new species of organisms. These technologies - far from the out-of-control nightmare depicted in science fiction - have the power to improve human and animal health, increase our intelligence, enhance our memory, and even extend our life span.

In Unfit for Purpose, biologist and broadcaster Adam Hart explores the mismatch between our fundamental biology and the modern world we have created. In each chapter Adam reveals the many ways in which biological adaptations that evolved to help us survive and thrive now work against us. For example, in the modern world stress is a killer, but how did 'fight or flight' instincts turn from life-savers to life-takers? Obesity might be a disease now, but is it really just a troublesome side-effect of our complex evolutionary past?

We all know that we depend on elements for survival - from oxygen in the air we breathe to carbon in the molecular structures of all living things. But we seldom appreciate how, say, phosphorus holds our DNA together or how potassium powers our optic nerves enabling us to see.

Systems biology came about as growing numbers of engineers and scientists from other fields created algorithms which supported the analysis of biological data in incredible quantities. Whereas biologists of the past had been forced to study one item or aspect at a time, due to technical and biological limitations, it suddenly became possible to study biological phenomena within their natural contexts.

From the humble drone to the fittingly named worker to the queen herself - who is more a slave than a monarch - the hive world, Andrew Coté reveals, is full of strivers and slackers, givers and takers, and even some insect promiscuity (startlingly similar to the prickly human variety). Written with Coté’s trademark humor, acumen, and a healthy dose of charm, Honey and Venom illuminates the obscure culture of New York City “beeks” and the biology of the bees themselves for both casual readers and bee enthusiasts.

El ojo desnudo reconstruye una historia de nuestro conocimiento de la visión y de la luz y nos ofrece la explicación de por qué vemos como vemos y cómo hemos alcanzado a comprender fenómenos que van mucho más allá de lo que nuestros sentidos nos permiten detectar.

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.
