The Poisoners is a history of four devastating chapters in the making of the region, seen through the disturbing use of toxins and accusations of poisoning circulated by soldiers, spies, and politicians in Zimbabwe and South Africa.

Imraan Coovadia’s fascinating new book exposes the secret use of poisons and diseases in the Rhodesian bush war and independent Zimbabwe, and the apparent connection to the 2001 anthrax attacks in the United States; the enquiry into the chemical and biological warfare programme in South Africa known as Project Coast, discovered through the arrest and failed prosecution of Dr Wouter Basson; the use of toxic compounds such as Virodene to treat patients at the height of the Aids epidemic in South Africa, and the insistence of the government that proven therapies like Nevirapine, which could have saved hundreds of thousands of lives, were in fact poisons; and the history of poisoning and accusations of poisoning in the modern history of the African National Congress, from its guerrilla camps in Angola to Jacob Zuma’s suggestion that his fourth wife collaborated with a foreign intelligence agency to have him murdered.

But The Poisoners is not merely a book of history. It is also a meditation, by a most perceptive commentator, on the meaning of race, on the unhappy history of black and white in southern Africa, and on the nature of good and evil.

The story of YouTube, the global phenomenon which single-handedly upended traditional media and transformed Google into one of the world's most profitable companies.

Since 2005, YouTube has exploded, giving a platform to unique and valuable voices, but also to propaganda, misinformation and illicit videos. The algorithm which determines whether a channel lives or dies - how or when videos are seen, and how much creators earn through advertising - is notoriously secretive, remaining a mystery to consumers and broadcasters alike. At the same time, the site is massively profitable for parent company Google, helping turn it into one of the most influential powers on the planet.

In Like, Comment, Subscribe, Bloomberg tech journalist Mark Bergen delivers the definitive account on YouTube, detailing how it started, how it works and ultimately how it drives Google's success. It can be seen as the story of a technical marvel that has upended traditional media and created stars out of everyday people, or the story of the rise of a ruthless advertising conglomerate with little regard for its impact on the world beyond the bottom line - but in reality, it's the story of both.

A brilliant takedown and exposé of the great con job of the twenty-first century—the metaverse, crypto, space travel, transhumanism—being sold by four billionaires (Peter Thiel, Mark Zuckerberg, Marc Andreesen, Elon Musk), leading to the degeneration and bankruptcy of our society.

At a time when the crises of income inequality, climate, and democracy are compounding to create epic wealth disparity and the prospect of a second American civil war, four billionaires are hyping schemes that are designed to divert our attention away from issues that really matter. Each scheme—the metaverse, cryptocurrency, space travel, and transhumanism—is an existential threat in moral, political, and economic terms.

In The End of Reality¸ Jonathan Taplin provides perceptive insight into the personal backgrounds and cultural power of these billionaires—Peter Thiel, Elon Musk, Mark Zuckerberg, and Marc Andreesen (“The Four”) —and shows how their tech monopolies have brought middle-class wage stagnation, the hollowing out of many American towns, a radical increase in income inequality, and unbounded public acrimony. Meanwhile, the enormous amount of taxpayer money to be funneled into the dystopian ventures of "The Four," the benefits of which will accrue to billionaires, exacerbate these disturbing trends.

The End of Reality is both scathing critique and reform agenda that replaces the warped worldview of "The Four" with a vision of regenerative economics that seeks to build a sustainable society with healthy growth and full employment.

A true-life scientific adventure story, this thrilling book takes the reader deep into South African caves to discover fossil remains that compel a monumental reframing of the human family tree.

In the summer of 2022, Lee Berger lost 50 pounds in order to wriggle though impossibly small openings in the Rising Star cave complex in South Africa—spaces where his team has been unearthing the remains of Homo naledi, a proto-human likely to have coexisted with Homo sapiens some 250,000 years ago. The lead researcher on the site, still Berger had never made his way into the dark, cramped, dangerous underground spaces where many of the naledi fossils had been found. Now he was ready to do so.

Once inside the cave, Berger made shocking new discoveries that expand our understanding of this early hominid—discoveries that stand to alter our fundamental understanding of what makes us human. So what does it all mean?

Join Berger on the adventure of a lifetime as he explores the Rising Star cave system and begins the complicated process of explaining these extraordinary finds—finds that force a rethinking of human evolution, and discoveries that Berger calls “the Rosetta stone of the human mind.”

Youth Revolution is the inspirational story of how a sixteen-year-old high-school student from Johannesburg, Kiara Nirghin, overcame huge health obstacles to win the grand prize at the 2016 International Google Science Fair for her unique and innovative solution to worldwide drought. Having experienced bacterial meningitis, undiagnosed bilharzia and severe weight loss, Kiara was forced to postpone her school career for hospitalisation, with a real chance of losing her hearing, her sight and the use of her limbs.

Youth Revolution not only covers her journey from the hospital bed to the stage as the winner of the science award, but also looks at issues surrounding stagnant youth innovation, while considering the dangers of lacking diversity in STEM (science, technology, engineering and maths). It also includes contributions from prominent women in science and education, among them Malala Yousafzai, VP of Education and University Programs for Google and the recipient of the L’Oréal-UNESCO Award for Women in Science.

Youth Revolution is a deeply human and truly inspirational real-life story that will enthral teenagers and adults alike, and proves that even ‘ordinary’ teenagers can do extraordinary things.

This well-respected book introduces readers to the theory and application of modern numerical approximation techniques. Providing an accessible treatment that only requires a calculus prerequisite, the authors explain how, why, and when approximation techniques can be expected to work-and why, in some situations, they fail. A wealth of examples and exercises develop readers' intuition, and demonstrate the subject's practical applications to important everyday problems in math, computing, engineering, and physical science disciplines. Three decades after it was first published, Burden, Faires, and Burden's NUMERICAL ANALYSIS remains the definitive introduction to a vital and practical subject.

An interrogation of why we don't talk to strangers, what happens when we do, and why it affects everything from the rise and fall of nations to personal health and wellbeing, in the tradition of Susan Cain's Quiet and Rutger Bregman's Humankind.

When was the last time you spoke to a stranger? In our cities, we stand in silent buses and tube carriages, barely acknowledging one another. Online, we retreat into silos and carefully curate who we interact with. But while we often fear strangers, or blame them for the ills of society, history and science show us that they are actually our solution. Throughout human history, our attitude to the stranger has determined the fate and wellbeing of both nations and individuals. A raft of new science confirms that the more we open ourselves up to encounters with those we don't know, the healthier we are.

In The Power of Strangers, with the help of sociologists, psychologists, neuroscientists, theologians, philosophers, political scientists and historians, Joe Keohane learns how we're wired to sometimes fear, distrust and even hate strangers, and discovers what happens to us when we indulge those biases. At the same time, he digs into a growing body of cutting-edge research on the surprising social and psychological benefits that come from talking to strangers; how even passing interactions can enhance empathy, happiness, and cognitive development, ease loneliness and isolation, and root us in the world, deepening our sense of belonging.

Warm, erudite and profound, this deeply researched book will make you reconsider how you perceive and approach strangers: paradoxically, strangers can help us become more fully ourselves.
