On 14 September 2015, after 50 years of searching, gravitational waves were detected for the first time and astronomy changed for ever. Until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays and the rest. But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead. At the two 4-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015 they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a new, powerful path to understand the workings of the universe.

Nearly 60 years ago, Nobel Prize-winners Arno Penzias and Robert Wilson stumbled across a mysterious hiss of faint radio static that was interfering with their observations. They had found the key to unravelling the story of the Big Bang and the origin of our universe. That signal was the Cosmic Microwave Background (CMB), the earliest light in the universe, released 379,000 years after the Big Bang. It contains secrets about what happened during the very first tiny increments of time, which had consequences that have rippled throughout cosmic history, leading to the universe of stars and galaxies that we live in today. This is the enthralling story of the quest to understand the CMB radiation and what it can tell us of the origins of time and space, from bubble universes to a cyclical cosmos – and possibly leading to the elusive theory of quantum gravity itself.

All the matter and light we can see in the universe makes up a trivial 5 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. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

A compelling and disquieting journey through the history and science of epidemics. 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. But while we chase the diseases we are already aware of, new ones are constantly emerging, like the coronavirus that spread across the world in 2020. At the same time, antimicrobial resistance is harnessing infections that we once knew how to control, enabling them to thrive once more. Meera Senthilingam presents a timely look at humanity’s ongoing battle against infection, examining the successes and failures of the past, along with how we are confronting the challenges of today, and our chances of eradicating disease in the future.

Dreams, schemes and opportunity as space opens for tourism and commerce. Twentieth century space exploration may have belonged to state-funded giants such as NASA, but there is a parallel history which has set the template for the future. 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. At the same time, other companies plan to mine the Moon for helium-3, or asteroids for precious metals. Science writer Andrew May takes an entertaining, in-depth look at the triumphs and heroic failures of our quixotic quest to commercialise the final frontier.

The controversial science that claims to have revolutionised economics. For centuries, economics was dominated by the idea that we are rational individuals who optimise our own ‘utility’. Then, in the 1970s, psychologists demonstrated that the reality is a lot messier. We don’t really know what our utility is, and we care about people other than ourselves. We are susceptible to external nudges. And far from being perfectly rational we are prone to ‘cognitive biases’ with complex effects on decision-making, such as forgetting to prepare for retirement. David Orrell explores the findings from psychology and neuroscience that are shaking up economics – and that are being exploited by policy-makers and marketers alike, to shape everything from how we shop for food, to how we tackle societal happiness or climate change. Finally, he asks: is behavioural economics a scientific revolution, or just a scientific form of marketing?

Extraterrestrial life is a common theme in science fiction, but is it a serious prospect in the real world? Astrobiology is the emerging field of science that seeks to answer this question. 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. Along the way the book addresses key questions such as the riddle of Fermi’s paradox (‘Where is everybody?’) and the crucial role of DNA and water – they’re essential to ‘life as we know it’, but is the same true of alien life? And the really big question: when we eventually find extraterrestrials, will they be friendly or hostile?

The ultimate non-technical guide to the fast-developing world of quantum computing Computer technology has improved exponentially over the last 50 years. But the headroom for bigger and better electronic solutions is running out. Our best hope is to engage the power of quantum physics. ‘Quantum algorithms’ had already been written long before hardware was built. These would enable, for example, a quantum computer to exponentially speed up an information search, or to crack the mathematical trick behind internet security. However, making a quantum computer is incredibly difficult. Despite hundreds of laboratories around the world working on them, we are only just seeing them come close to ‘supremacy’ where they can outperform a traditional computer. In this approachable introduction, Brian Clegg explains algorithms and their quantum counterparts, explores the physical building blocks and quantum weirdness necessary to make a quantum computer, and uncovers the capabilities of the current generation of machines.

The Higgs boson is the rock star of fundamental particles, catapulting CERN, the laboratory where it was found, into the global spotlight. But what is it, why does it matter, and what exactly is CERN? In the late 1940s, a handful of visionaries were working to steer Europe towards a more peaceful future through science, and CERN, the European particle physics laboratory, was duly born. James Gillies tells the gripping story of particle physics, from the original atomists of ancient Greece, through the people who made the crucial breakthroughs, to CERN itself, one of the most ambitious scientific undertakings of our time, and its eventual confirmation of the Higgs boson. Weaving together the scientific and political stories of CERN’s development, the book reveals how particle physics has evolved from being the realm of solitary genius to a global field of human endeavour, with CERN’s Large Hadron Collider as its frontier research tool.
