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.

The field of mind-body medicine is plagued by wild claims that mislead patients and instil false hope. But as scientists in a range of fields uncover solid evidence that our minds influence our bodies quite profoundly, there is now great promise, too. Jo Marchant attempts to use scientific research to find out if alternative medicines work; if our thoughts, beliefs and emotions influence our physical health; and if we can train our brains to heal our bodies.

Brian Clegg was always fascinated by Isaac Asimov's classic Foundation series of books, in which the future is predicted using sophisticated mathematical modelling of human psychology and behaviour. Only much later did he realise that Asimov's 'psychohistory' had a real-world equivalent: game theory. Originating in the study of probabilistic gambling games that depend on a random source—the throw of a dice or the toss of a coin—game theory soon came to be applied to human interactions: essentially, what was the best strategy to win, whatever you were doing?

The discovery of radium in the late 19th century prompted a flurry of experiments to scope the limits of its potential applications. Half Lives tells the fascinating, curious, sometimes macabre story of the element through its ascendance as a desirable item - a present for a queen, a prize in a treasure hunt, a glow-in-the-dark dance costume, a boon to the housewife and an ingredient in a startling host of consumer products - to its role as a cure-all in everyday 20th-century life.  

Over 50 years ago, astronomers launched the world's first orbiting telescope. This allowed them to gaze further into outer space and examine anything that appears in the sky above our heads, from comets and planets to galaxy clusters and stars. Since then, almost 100 space telescopes have been launched from Earth and are orbiting our planet, with 26 still active and relaying information back to us. In Eyes in the Sky, science writer Andrew May takes us on a journey into space.

The twelve sheep have come into his life at just the right moment. After years of hard work, John felt a deep tiredness creeping up on him, a sadness that he couldn't shrug off. Having always sought spiritual guidance, he comes to realize that, in addition to the soothing words of literature and philosophy, perhaps the way ahead involves this simple flock of sheep. In the hard work of livestock rearing, in the long nights in the shed helping the sheep to lamb, he can reflect on what life truly means.

Physics informs our understanding of how the world works - but more than that, key breakthroughs in physics have transformed everyday life. We journey back to 10 separate days in history to understand how particular breakthroughs were achieved, meet the individuals responsible and see how each breakthrough has influenced our lives.

Ours is the age of global warming. Rising sea levels, extreme weather, forest fires. Climate scientist Peter Stott reveals the bitter fight to get international recognition for what, among scientists, has been known for decades: human activity causes climate change. Across continents and against the efforts of sceptical governments, prominent climate change deniers and shadowy lobbyists, Hot Air is the urgent story of how the science was developed, how it has been repeatedly sabotaged and why humanity hasn't a second to spare in the fight to halt climate change.

The Fens is Britain's most distinctive, complex, man-made and least understood landscape. Francis Pryor has lived in, excavated, farmed, walked and loved the Fen Country for more than 40 years: its levels and drains, its soaring churches and magnificent medieval buildings. In The Fens, he counterpoints the history of the Fenland landscape and its transformation with the story of his own discovery of it as an archaeologist.

In 1929, a 22-year-old maverick named Frank Whittle - a self-taught aeronautical obsessive and risk-takingly brilliant RAF pilot - presented a blueprint for a revolutionary, jet-powered aircraft engine to the Air Ministry. His idea had the potential to change the course of history, but it was summarily rejected. In this meticulously researched biography, Duncan Campbell-Smith charts Whittle's stoic efforts to build his jet engine in the interwar years.

Sally Coulthard explores the miraculous world of the earthworm, the modest little creature without whom life as we know it would not be possible. For Charles Darwin - who estimated every acre of land contained 53,000 earthworms - the humble earthworm was the most important creature on the planet. And yet, most people know almost nothing about these little engineers of the earth. We take them for granted but, without the earthworm, the world's soil would be barren and our gardens, fields and farms wouldn't be able to grow the food and support the animals we need to survive.

A garden fork. Preferably forged from a single piece of steel. Not because, given a good enough shove, its tines would pierce a zombie's skull as easily as an overripe melon but because come the end of the world, gardening will be what saves your skin. This book, which is aimed at beginners and more seasoned gardeners alike, will tell you what you need; provide the basics of gardening language and technique; provide a planting plan; debunk gardening myths; and show you how to preserve your food and grow your own medicine even if there are no zombies around.  

Greta Thunberg, author of No One Is Too Small to Make a Difference, has directed the attention of adults and her peers alike to issues crucial to the future of the planet, and the heads of even the youngest children have been filled with questions. Global warming, the greenhouse effect, fossil fuels - what do they all mean? What are biodiversity and sustainable development? Who is studying the changes that are taking place here on Earth? Which sources are reliable? What action can I take? 

Today's unprecedented pace of change leaves many people wondering what new technologies are doing to our lives. Has social media robbed us of our privacy and fed us with false information? Are the decisions about our health, security and finances made by computer programs inexplicable and biased? Will these algorithms become so complex that we can no longer control them? Are robots going to take our jobs? John Browne presents an impassioned defence of progress and innovation and argues that we need not and must not put the brakes on technological advance.

What does it mean to have a healthy, happy brain? Especially in the current climate, where our lifestyles are changing dramatically and our movements are being restricted, getting to know the factors that affect our brain function and the things we can actively do to improve it is crucial. Written in an accessible and engaging way for the nonscientist, this will be a comprehensive and up-to-date look at our current understanding, what a fast-changing field it is and how much we still don't know when it comes to disorders of the brain.

Taking you on an in-depth tour of your everyday household products, Anna Turns reveals the harmful chemicals that lurk inside your home, the damage they can cause and helpful swaps and tips to avoid them wherever you can. Go Toxic Free is a vital guide to help us all make important changes to our lifestyles and consumption to help reduce the devastating impact of chemical pollution.

To lark is to get out and about, to explore the world around us and to discover the little treasures hiding in plain sight. We think, of course, of mudlarking, but there is also beachlarking, fieldlarking or even simply exploring your own home with fresh eyes. In this field guide, Lara teaches us how to lark for ourselves. There are charts, tips and lists throughout to help identify finds. From tide tables for mudlarkers to a flint guide for fieldlarkers, this book is richly informative. Like a journal, it invites you to interact - to make notes and record finds along the way.

Even before Apollo 11 landed on the Moon, private companies were exploiting space via communication satellites - a sector that is seeing exponential growth in the internet age. In human spaceflight, too, commercialisation is making itself felt. Billionaire entrepreneurs Elon Musk, Jeff Bezos and Richard Branson have long trumpeted plans to make space travel a possibility for ordinary people and those ideas are inching ever closer to reality. 

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.

Maybe it's the weirdness of the weather. Maybe it's another way to pour scorn on politicians. Maybe the steady stream of headlines about fires, floods and droughts is finally starting to get to us. Whatever it is, for more and more of us, climate change is shifting from a shadowy fear in the backs of our minds to something we feel we need to get a handle on. Climate change may be a horror story, but, as Our Biggest Experiment shows, the tale of how we discovered it isn't.
