Interviews with veterinarians, nutritionists and researchers about topics related to beef cattle production in Canada

International sex researcher, neuroscientist, and columnist Debra Soh debunks popular gender myths in this scientific examination of the many facets of gender identity that “is not only eminently reasonable and beautifully-written, it is brave and vital” (Ben Shapiro, number-one New York Times best-selling author).

Life is the most extraordinary phenomenon in the known universe; but how did it come to be? Even in an age of cloning and artificial biology, the remarkable truth remains: Nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we still missing a vital ingredient in its creation?

For the first time in history, the secrets of the living brain are being revealed by a battery of high-tech brain scans devised by physicists. Now what was once solely the province of science fiction has become a startling reality. Recording memories, telepathy, videotaping our dreams, mind control, avatars, and telekinesis are not only possible; they already exist.

A highly infectious, deadly virus from the central African rain forest suddenly appears in the suburbs of Washington, D.C. There is no cure. In a few days, 90 percent of its victims are dead. A secret military SWAT team of soldiers and scientists is mobilized to stop the outbreak of this exotic "hot" virus. The Hot Zone tells this dramatic story, giving a hair-raising account of the appearance of rare and lethal viruses and their "crashes" into the human race. Shocking, frightening, and impossible to ignore, The Hot Zone proves that truth really is scarier than fiction.

Not since the atomic bomb has a technology so alarmed its inventors that they warned the world about its use. Not, that is, until the spring of 2015, when biologist Jennifer Doudna called for a worldwide moratorium on the use of the new gene-editing tool CRISPR - a revolutionary new technology that she helped create - to make heritable changes in human embryos.

Once again, John Gierach tells the world why the pastime of fly-fishing makes so much sense—except when it doesn't. In sparkling prose, with more than a touch of humor, he recalls the joys of landing that trout he's been watching for the last hour—and then losing an even fatter one a little later. Joy and frustration mix in Gierach's latest appreciation of the fly-fishing life as he takes us from his home waters on the Front Range of the Rockies in Colorado to fishing meccas all over North America.

When Donald Johanson found a partial skeleton, approximately 3.5 million years old, in a remote region of Ethiopia in 1974, a headline-making controversy was launched that continues today. Bursting with all the suspense and intrigue of a fast-paced adventure novel, here is Johanson’s lively account of the extraordinary discovery of “Lucy.” By expounding the controversial change Lucy makes in our view of human origins, Johanson provides a vivid, behind-the-scenes account of the history of paleoanthropology and the colorful, eccentric characters who were, and are, a part of it.

In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

James Herriot brings back familiar and much-loved friends, including his partner Siegfried and his most lucrative patient, the delightful Tricki Woo. There are some some new arrivals too, such as the abandoned and terrified mongrol Titch who finds the perfect home with a gruff grocer and feral kittens Olly and Ginny who live in James and wife Helen's back garden. Above all, the veterinary practise in Darrowby is enlivened by a marvelouslly eccentric assistant, Calum Buchanan, who arrives with a pet badger and proceeds to add dogs, owls and a monkey called Mortimer to his growing menagerie.

From award-winning author Merilyn Simonds, a remarkable biography of an extraordinary woman—a Swedish aristocrat who survived the Russian Revolution to become an internationally renowned naturalist, one of the first to track the mid-century decline of songbirds.

In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy.

Adored by children and adults alike, tyrannosaurus is the most famous dinosaur in the world, one that pops up again and again in pop culture, often battling other beasts such as King Kong, triceratops, or velociraptors in Jurassic Park. But despite the hype, tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right and are among the best-studied of all dinosaurs.

Fifty thousand years ago, we were not the only species of human in the world. There were at least four others, including the Neanderthals, Homo floresiensis, Homo luzonesis and the Denisovans. At the forefront of the latter's ground-breaking discovery was Oxford Professor Tom Higham. In The World Before Us, he explains the scientific and technological advancements.

John T. Cacioppo's groundbreaking research topples one of the pillars of modern medicine and psychology: the focus on the individual as the unit of inquiry. By employing brain scans, monitoring blood pressure, and analyzing immune function, he demonstrates the overpowering influence of social context - a factor so strong that it can alter DNA replication.

In 12 fiercely funny, mind-expanding chapters, Dawkins explains how the natural world arose without a designer - the improbability and beauty of the "bottom-up programming" that engineers an embryo or a flock of starlings - and challenges head-on some of the most basic assumptions made by the world’s religions: Do you believe in God? Which one? Is the Bible a "Good Book"? Is adhering to a religion necessary, or even likely, to make people good to one another? Outgrowing God is a concise, provocative guide to thinking for yourself.

In her groundbreaking and best-selling book Animals in Translation, Temple Grandin drew on her own experience with autism as well as her distinguished career as an animal scientist to deliver extraordinary insights into how animals think, act, and feel. Now she builds on those insights to show us how to give our animals the best and happiest life - on their terms, not ours. Animals Make Us Human is the culmination of almost thirty years of research, experimentation, and experience.

Tell a stranger that you talk to yourself, and you’re likely to get written off as eccentric. But the truth is that we all have a voice in our head. When we talk to ourselves, we often hope to tap into our inner coach but find our inner critic instead. When we’re facing a tough task, our inner coach can buoy us up: Focus - you can do this. But, just as often, our inner critic sinks us entirely: I’m going to fail. They’ll all laugh at me. What’s the use?

Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells - taken without her knowledge - became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than 60 years. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects.

In the New York Times bestseller Brain Rules, Dr. John Medina, a molecular biologist, shares his lifelong interest in how the brain sciences might influence the way we teach our children and the way we work. In each chapter, he describes a brain rule - what scientists know for sure about how our brains work - and then offers transformative ideas for our daily lives. Medina’s fascinating stories and infectious sense of humor breathe life into brain science.
