An ambitious scientific project is unfolding in the desert of South Africa, with a multidecade time line that will eventually see expansion into Western Australia—a project that is detailed and celebrated in this book on the Square Kilometre Array (SKA). The SKA will be the largest and most sensitive radio telescope, expanding the capabilities of scientific probing and addressing significant unanswered questions about the universe, such as the formation of galaxies and the nature of gravity. Technology correspondent Sarah Wild covers the important development with this exploration of its implications on an international scale as well as its South African context, from the first telescope built in the country in the 1960s to Xhosa starlore. Interspersed with |Xam bushmen stories rewritten from original manuscripts, this consideration is an informed and thoughtful insight into an exciting step in astronomy.

<div> Humans are the dominant species on the planet. But how did we get here? Human Origins takes the reader on a fascinating 7-million-year journey from our earliest primordial ape-like roots through to the present day. For almost a hundred years, scientists have been trying to decipher the secrets of humanity's evolution. At first, they relied on rare pieces of ancient skulls and bone fragments. But every year, they make new discoveries, uncover new fossils and develop new techniques to tease apart the story of our evolution. So far, from skeletons to teeth, humanity has found more than 6,000 hominin individuals. These individuals span several species, all of which tell the tale of human evolution: how our brains changed over time, what we ate, how we lived. Including the latest scientific findings, Human Origins will also look at some of the biggest questions that remain: What makes humans unique? Where did the Neanderthals go? And are humans still evolving? </div>
