Our nearest planetary neighbor has been the subject of endless fascination and wide-ranging theories throughout history. Is there life on Mars? Was there ever life on Mars? What was the atmosphere like thousands or millions of years ago? From Percival Lowell, who built his own observatory so he could dedicate himself to studying the red planet, to NASA landing the car-sized Curiosity rover in 2012, this book traces Scientific American's coverage of the observation and exploration of Mars. 

As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects and plans for high-tech hardware that could deflect an incoming object from a collision course - a procedure depicted in several Hollywood movies.

Following 10 years of detailed investigation, documentary film-maker Guillaume Coudray presents a powerful examination of the use of nitro-additives in meat. As he reveals, most mass-produced processed meats, and now even many ‘artisanal’ products, contain chemicals that react with meat to form cancer-causing compounds. He tells the full story of how, since the 1970s, the meat-processing industry has denied the health risks because these additives make curing cheaper and quicker, extending shelf life and giving meat a pleasing pink colour.

Blood carries life, yet the sight of it makes people faint. It is a life-saver, and can transmit deadly infections. It is medicine, and a commodity dearer than oil. Each of us has nine to 12 pints of it, yet many don’t know their own blood type. For all its ubiqutousness, menstruation is perhaps the single most demonized biological event. In Nine Pints, Rose George takes us from ancient practices of bloodletting to a cutting-edge trauma ward. 

A powerful reflection on life in isolation, in pursuit of the dream of Mars. In 2013 Kate Greene moved to Mars. On NASA’s first HI-SEAS simulated Mars mission in Hawaii, she lived for four months in an isolated geodesic dome with her crewmates, gaining incredible insight into human behaviour in tight quarters, as well as the nature of boredom, dreams and isolation that arise amidst the promise of scientific progress and glory. 

From the secret fossils of London to the three-billion-year-old rocks of the Scottish Highlands, and from state-of-the-art Californian laboratories to one of the world's most dangerous volcanic complexes hidden beneath the green hills of western Naples, set out on an adventure to those parts of the world where the Earth's life-story is written into the landscape. Helen Gordon turns a novelist's eye on the extraordinary scientists who are piecing together this planetary drama.

Written by experts and offering listeners the opportunity to pass off appropriated knowledge as their own, the Bluffer's Guides provide hard fact masquerading as frivolous observation in one witty, easy listen. Instantly acquire all the knowledge you need to pass as an expert in the world of quantum physics. Never again confuse a boson with a hadron, a fermion with a meson, or a photon with a lepton or an electron. If in doubt, always fall back on a bluffon.

From atomic structures to theories about magnetic forces, scientific progress has given us a good grasp on the properties of many different materials. However, science cannot tell us how to measure the temperature of steel just by looking at it, or how to sculpt stone into all kinds of shapes, or what it feels like to blow up a balloon of glass. Handmade is the story of materials through making and doing. Author and material scientist Anna Ploszajski journeys into the domain of makers and craftspeople to comprehend how the most popular materials really work.

Einstein's special theory of relativity made time travel to the future a possibility, and later his general theory of relativity showed us that loops in spacetime could exist, meaning that we might be able to bend time backwards, too. But what are the practicalities of making time travel possible? What do we still need to know? How do we deal with any paradoxical twists in time - and could quantum physics hold the answer?

From the pioneers of Los Alamos who got up close and personal with the cores of atomic bombs, to the hapless engineers in Soviet fuel-processing plants who unwittingly mixed up a disaster in a bucket, and from the terrifying impact of a tsunami at Fukushima to the mystery of the recent Russian incident, Meltdown explores the past and future of this extraordinary and potentially lethal source of infinite power 

For the past six years, Whitney Dafoe has been confined to a bedroom in the back of his parents' home, unable to walk, eat or speak. His diagnosis? The mysterious disease myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS) which affects 20 million people around the world who largely suffer in silence because the condition is little known and much misunderstood. Waiting for Superman follows Whitney's father, groundbreaking geneticist Ron, as he uncovers new possibilities for treatments and potentially a cure. 

Spotting a face in a crowd is so easy, you take it for granted. But how you do it is one of science's great mysteries. And vision is involved with so much of everything your brain does. Explaining how it works reveals more than just how you see. In We Know It When We See It, Harvard neuroscientist Richard Masland tackles vital questions about how the brain processes information - how it perceives, learns and remembers - through a careful study of the inner life of the eye.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

In an era of rapidly developing technology and renewed ambition, the 21st century has ushered in an exciting new age of space flight. But what has brought us to this point in our exploration of the universe? And what does the future of space travel hold? From the amazing technology that has enabled us to look beyond the clouds to the possibilities of space tourism, 10 Short Lessons in Space Travel takes a timely look at the essential lessons learned from our voyages into outer space.

The 13th person to walk on the moon could soon be part of a crew establishing a base on the lip of a crater at the lunar south pole. The discovery of ice in the eternal shadows of the polar regions transforms our ability to live on the moon. From bases on the moon we can make the long, lonely and dangerous voyage to Mars, where there is also ice. The obstacles are many, not least the fragilities of the human body. And what type of world would the first Mars explorers find?

Science journalist Lydia Denworth takes us in search of the biological, psychological and evolutionary foundations of this important bond. She finds that the human capacity for friendship is as old as humanity itself, when tribes of people on the African savanna grew large enough for individuals to seek meaningful connection with those outside their immediate families. Lydia meets scientists at the frontiers of brain and genetics research and discovers that friendship is reflected in our brain waves, our genomes and our cardiovascular and immune systems.

For centuries mankind has waged war against the infections that, left untreated, would have the power to wipe out communities, or even entire populations. Yet for all our advanced scientific knowledge, only one human disease - smallpox - has ever been eradicated globally. In recent years, outbreaks of Ebola and Zika have provided vivid examples of how difficult it is to contain an infection once it strikes and the panic that a rapidly spreading epidemic can ignite. 

Over the course of 14 billion years, humanity has gained the ability not only to imagine the future, but to design and engineer it. Entertaining and profound, Future Rising by Dr Andrew Maynard, provides a highly original perspective on our relationship with the future. Written to be easy to pick up and hard to stop listening to, Future Rising starts at the big bang and traces a pathway along the emergence of intelligent life, through what makes humans uniquely capable of creating different futures, to the profound responsibilities that this comes with. 

An earthquake shatters Haiti and a hurricane slices through Texas. We hear that nature runs rampant, seeking to destroy us through these 'natural disasters'. Science recounts a different story, however: disasters are not the consequence of natural causes; they are the consequence of human choices and decisions. we put ourselves in harm's way; we fail to take measures which we know would prevent disasters, no matter what the environment does.

Shining a light on the most profound insights revealed by modern physics, Jim Al-Khalili invites us all to understand what this crucially important science tells us about the universe and the nature of reality itself. Al-Khalili begins by introducing the fundamental concepts of space, time, energy, and matter, and then describes the three pillars of modern physics - quantum theory, relativity, and thermodynamics - showing how all three must come together if we are ever to have a full understanding of reality.
