This book is a totally fresh approach to observing birds in southern Africa. It affords you the opportunity to gather previously inaccessible and indecipherable information in the form of tracks and signs left behind by our avifauna. The book explores the unique details of the spoor, or tracks, of many species of birds. This is done in multiple ways including by observing their droppings, examining their feeding behaviour as well as their general nesting structures.
It’s remarkable how tracks and signs in nature help you to enrich your knowledge of bird species, providing knowledge as straightforward as the shape of the individual nests of our various species of weaver, or the ability to recognise and understand the role of a drum-site in the life of a bearded woodpecker, or even being able to see the subtle signs of a cardinal woodpecker on the various acacia pods which host its larval food.
Louis Liebenberg has generously provided some sketches of spoor he has made for his own publications, making these clear schematics available to assist with identification. Skulls, feathers, beaks and egg shells are also occasionally encountered, and a few examples of these will be included, as they also tell a story of a bird which has passed by. This approach to southern Africa’s birdlife will add tremendously to how we experience our wonderful avifauna.
A virologist's insight into how viruses evolve and why global epidemics are inevitable.
In 1993 a previously healthy young man was drowning in the middle of a desert, in fluids produced by his own lungs. This was the beginning of the terrifying Sin Nombre hantavirus epidemic and the start of a scientific journey that would forever change our understanding of what it means to be human. After witnessing the Sin Nombre outbreak, Dr Frank Ryan began researching viral evolution and was astonished to discover that it's inextricable from the evolution of all life on Earth. From AIDS and Ebola to the common cold, Ryan explores the role of the virus within every ecosystem on the planet.
His gripping conclusions shed new light on the natural world, proving that what doesn't kill you really does make you (and your species) stronger.

A wonderful successor to A Short History of Nearly Everything, this book will have you marvelling at the form you occupy, and celebrating the genius of your existence, time and time again.
A journey through the history and science of epidemics and pandemics – from measles to coronavirus.
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, anti-microbial 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.
Wat Moet Ons Met Ons Kerk Doen? is 'n poging om te probeer verstaan waar ons as Afrikaners teologies vandaan kom, watter kragte en magte ons en ons Kerk gevorm het en hoe ons Kerk tans daar uitsien.
Die N.G.Kerk was 'n belangrike en rigtinggewende rolspele in die opheffing van die Afrikaner na die Britse vergrype tydens en na die Tweede Vryheidsoorlog. Tans word die N.G.Kerk ervaar as 'n instansie wat ongevoelig teenoor die geestelike behoeftes van haar lidmate staan.

In this book, Adrian Koopman describes the complex relationship between birds, the Zulu language and Zulu culture. A number of chapters look at the underlying meaning of bird names, and here we will find that the Zulu name of the Goliath Heron means ‘what gives birth to baby crocodiles’, the dikkop (umbangaqhwa) means ‘what causes frost’, and the African Hoopoe is a party-goer who wears a colourful blanket.
The book goes further than just Zulu names, exploring the underlying meanings of bird names from other South African languages and languages from Central and East Africa. Here we find birds with names that translate as ‘cool-porridge’, ‘kiss-banana-flower’ and ‘waiter-at-the-end-of-the furrow’.
A focus on Zulu traditional oral literature details the roles birds have played in Zulu praise poetry (including the praise poems of certain birds themselves) and in proverbs, riddles and children’s games. Also considered is traditional bird lore, examining the role played by various species as omens and portents, as indicators of bad luck and evil, as forecasters of rain and storm, and as harbingers of the seasons. Here we see that the Bateleur Eagle (ingqungqulu) is linked to war, the Southern Ground Hornbill (insingizi) to thunder and heavy rain, the Red-chested Cuckoo (uphezukokhono) to the start of the ploughing season, and the Jacobin Cuckoo (inkanku) to the start of summer.
Zulu Bird Names and Bird Lore discusses the Zulu Bird Name Project, a series of Zulu bird name workshops held between 2013 and 2017 with Zulu-speaking bird guides designed to confirm (or otherwise) all previously recorded Zulu names for birds, while at the same time devising new names for those without previously recorded names. The result has been a list of species-specific names for all birds in the Zulu-speaking region. Finally, the book turns to the role such new bird names can play in conservation education and in avi-tourism.
When Edwin Hubble looked into his telescope in the 1920s, he was shocked to find that nearly all of the galaxies he could see through it were flying away from one another. If these galaxies had always been travelling, he reasoned, then they must, at some point, have been on top of one another. This discovery transformed the debate about one of the most fundamental questions of human existence - how did the universe begin?
Every society has stories about the origin of the cosmos and its inhabitants, but now, with the power to peer into the early universe and deploy the knowledge gleaned from archaeology, geology, evolutionary biology and cosmology, we are closer than ever to understanding where it all came from. In The Origin of (almost) Everything, New Scientist explores the modern origin stories of everything from the Big Bang, meteorites and dark energy, to dinosaurs, civilisation, timekeeping, belly-button fluff and beyond.
From how complex life evolved on Earth, to the first written language, to how humans conquered space, The Origin of (almost) Everything offers a unique history of the past, present and future of our universe.
Your gut is astonishingly clever. It contains millions of neurons - as many as you would find in the brain of a cat - and is home to the microbiome, trillions of microbes that influence your mood, your immune system, and even your appetite.
In this groundbreaking book, Dr. Mosley takes us on a revelatory journey through the gut, showing how junk food and overuse of antibiotics have wiped out many good gut bacteria, leading to a modern plague of allergies, food intolerances, and obesity.
Drawing from the latest cutting-edge research, Dr. Mosley provides scientifically proven ways to control your cravings, boost your mood, and lose weight by encouraging a more diverse microbiome and increasing the good bacteria that keep you healthy.
Packed with delicious, healing recipes, meal plans, checklists, and tips, The Clever Guts Diet includes all the tools you need to transform your gut and your health, for life.
Everything you need to know about race (but were afraid to ask), previously published in 2015 as Black Brain, White Brain: Is Intelligence Skin Deep?.
In academic journals and on internet message boards, certain scientists and thinkers are laying siege to one of the great taboos. Could it be, they ask, that racism has a rational basis in science? These ideas are no longer limited to the fringe: race-based studies of intelligence have been discussed by thinkers such as Steven Pinker, Sam Harris and Jordan Peterson. If true, it would provide an intellectual foundation for so many of the attitudes that characterise the right wing, justifying inequality and discrimination. Gavin Evans tackles the nature vs nurture debate head-on, examining the latest studies on how intelligence develops and laying out new discoveries in genetics, palaeontology, archaeology and anthropology to unearth the truth about our shared past.
In doing so, Skin Deep demolishes the pernicious myth that our race is our destiny, and instead reveals what really makes us who we are.

The humble and industrious dung beetle is a marvellous beast: the 6 000 species identified so far are intricately entwined with human history and scientific endeavour.
These night-soil collectors of the planet have been worshipped as gods, worn as jewellery, and painted by artists. More practically, they saved Hawaii from ecological blight, and rescued Australia from plagues of flies. They fertilise soil, cleanse pastures, steer by the stars, and have a unique relationship with the African elephant (along with many other ungulates). Above all, they are the ideal subject for biological study in an evolving world.
In this sweeping history of more than 3 000 years, beginning with Ancient Egypt, scientist Marcus Byrne and writer, Helen Lunn capture the diversity of dung beetles and their unique behaviour patterns. Dung beetles’ fortunes have followed the shifts from a world dominated by a religion that symbolically incorporated them into some of its key concepts of rebirth, to a world in which science has largely separated itself from religion and alchemy.
With over 6 000 species found throughout the world, these unassuming but remarkable creatures are fundamental to some of humanity’s most cherished beliefs and have been ever present in religion, art, literature, science and the environment. They are at the centre of current gene research, play an important role in keeping our planet healthy, and some nocturnal dung beetles have been found to navigate by the starry skies. Outlining the development of science from the point of view of the humble dung beetle is what makes this charming story of immense interest to general readers and entomologists alike. This entertaining outline of the development of science from the the beetle’s perspective will enchant general readers and entomologists alike.
WHEN we eat may be as important as WHAT we eat.
Like most people, you probably wake up, get hungry for meals and doze off in bed around the same time every day. If you’ve ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. But for some people, that imbalance—difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon—is a constant. If you're one of those people, Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock.
Beginning with an in-depth explanation of the circadian clock—why it’s important, how it works, and how to know it isn’t working—The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn’t interfere with your body’s natural rhythm. Dr. Panda’s life changing methods show you how to prevent and reverse ailments like diabetes, cancer, and dementia, as well as microbiome conditions like acid reflux, heartburn, and irritable bowel disease.

'This book is packed with big ideas about life. Every chapter has something in it which made me think wow. Having worked in a major cancer charity for many years, Arney writes with genuine in-depth understanding and is a perfect guide.' Daniel M. Davis, author of The Beautiful Cure 'Rebel Cell is a bright, engaging read, fizzing with energy and metaphor. Kat Arney is a science writer for all of us - a powerful and talented story teller.' Stephen McGann 'Kat's book is Dynamite. A crystal clear reappraisal of the story behind that word we fear to mention.' Dallas Campbell, author of Ad Astra: An Illustrated Guide to Leaving the Planet Cancer has always been with us. It killed our hominid ancestors, the mammals they evolved from and the dinosaurs that trampled the ground before that. Tumours grow in pets, livestock and wild animals. Even tiny jelly-like Hydra - creatures that are little more than a tube full of water - can get cancer. Paradoxically, many of us think of cancer as a contemporary killer, a disease of our own making caused by our modern lifestyles. But that's not true. Although it might be rare in many species, cancer is the enemy lurking within almost every living creature. Why? Because cancer is a bug in the system of life. We get cancer because we can't not get it. Cancer starts when cells revolt, throwing off their molecular shackles, and growing and dividing out of control in a shambolic mockery of normal life. This is why we can't avoid cancer: because the very genes that drive it are essential for life itself. The revolution has raged, on and off, for millions of years. But it was only in the twentieth century that doctors and scientists made any significant progress in understanding and treating cancer, and it's only in the past few decades that we've finally begun to kick the mob's malignant arse. Now the game is changing. Scientists have infiltrated cancer's cellular rebellion and are finally learning its secrets. Geneticist and science writer Kat Arney takes the reader back to the dawn of life on planet earth right up to the present day to get to the heart of what cancer really is and how by better understanding it we might one day overcome it.

An enchanting biography of the most resonant - and most necessary - chemical element on Earth. Carbon. It is the building block of every cell that makes up every living thing. It is the essential component of the food we eat, the fuel we burn, the wood we use and the air we breathe. It is worth billions as a luxury and half a trillion as a necessity, but there are still mysteries to be solved about the element that can be both diamond and coal. Where does it come from, what does it do, and why, above all, does life need it? In Symphony in C, leading carbon scientist Robert M. Hazen takes us on a vibrant journey through the origin and evolution of life's most widespread element. The story unfolds in four movements - Earth, Air, Fire and Water - and transports us through nearly 14 billion years of cosmic history, explaining how carbon is formed in the hearts of stars and why all life forms - earthbound or alien - use it as the basis of their biology. Symphony in C is a sweeping chronicle of carbon from its birth amidst the stars to its unknowable life cycle deep within the Earth's core and its role in the evolution of all life in the universe.
Sunday Times Bestseller `Passionate and well-researched' Tatler `A must-read' Independent A social history of Labradors, and how they have become the world's most beloved dogs, by writer, presenter and long-time dog lover Ben Fogle. Labradors are the most popular breed of dog in the world. Not only a great family companion, they also excel at hunting, tracking, retrieving, guiding and rescuing. But where did the breed originally come from? How did it develop? When did black, yellow and chocolate Labradors first appear? Did they really all come from Labrador in Canada and are they really all related to just one dog? In this first history of the Labrador, Ben Fogle goes in search of what makes Labradors so special. Their extraordinary companionship, intelligence, work ethic and loyalty is captured by Ben as he weaves the story of the breed into his own story of his beloved Inca. Ben visits Canada, discovers hair-raising stories of early Labrador exploits and uncovers stories of RNIB Labradors and Labradors at war, Labradors as working dogs and every other manifestation of the Labrador's character. Exploring their origin, early characteristics, their use as gun dogs, as therapy dogs, as police dogs, as search and rescue dogs and last - and absolutely not least - as family pets, Ben tells the story of a dog breed which has captured our imagination and love for hundreds of years.

Salmon, one of the most determined, single-minded creatures on earth, have for hundreds of thousands of years succeeded in returning from the sea to their birth rivers to spawn - no matter the conditions or obstacles. But in recent years increasingly fewer are returning due to steady incursions into their habitat from dams, industry, and climate change. The salmon of the Pacific Rim are set for near extinction, just like the salmon that once filled the Atlantic Ocean.
Stronghold is an enthralling account of an unlikely visionary, Guido Rahr, and his mission to protect the world s last bastion of wild salmon. The reader is taken on wild and at times dangerous adventure, as we follow him from Oregon to Alaska to one of the world s last remaining wildernesses, in the Russian Far East - a landscape of ecological richness and diversity that is rapidly being developed for oil, gas, minerals, and timber.
As Guido befriends and navigates scientists, conservationists, corrupt officials, Russian oligarchs, unexpected allies, and impenetrable bureaucracies, he reveals the astonishing natural history of the endangered salmon, a species whose demise will reverberate across the planet. And he sets into motion a plan that can secure their survival.
