With two out of every 100 newborns in the United States now being test-tube babies, it raises a thought-provoking question: have we, in some way, always been "test-tube babies" from the beginning? From the helpless cries of an infant to the dominance of Earth's most powerful, humanity has embarked on an extraordinary journey—an epic odyssey across time and space. Our ascent on this Blue Planet is not merely a story of survival but a profound evolution and genesis, both real and symbolic. It's a rise that is as rapid as it is awe-inspiring.

What is the nature of the material world? How does it work? What is the universe and how was it formed? What is life? Where do we come from and how did we evolve? How and why do we think? What does it mean to be human? How do we know? There are many different versions of our creation story. This book tells the version according to modern science. It is a unique account, starting at the Big Bang and travelling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later.

The Mind of the Market will change the way we think about the economics of everyday life. Drawing on research from neuroeconomics, Michael Shermer explores what brain scans reveal about bargaining, snap purchases, and how trust is established in business. Utilizing experiments in behavioral economics, Shermer shows why people hang on to losing stocks and failing companies, why business negotiations often disintegrate into emotional tit-for-tat disputes, and why money does not make us happy.

The Evolution of Creationism is a compelling exploration of the enduring conflict between evolutionary science and creationist ideology. From the initial reactions to Darwin’s On the Origin of Species to the modern legal battles over science education, this book delves into the historical, cultural, and political forces shaping the debate. Through detailed analysis of key events—such as the Huxley-Wilberforce debate, the Scopes Trial, and contemporary Intelligent Design movements—this book exposes the shifting strategies of creationists and the scientific responses that have countered...

One of the biggest discoveries in physics, the quest for the Higgs boson demonstrates the value of a good theory. In July 2012, a Higgs-like particle was found near the energies scientists predicted. Now, armed with better evidence and better questions, the scientific process continues. In this audiobook, we’ve gathered our best reporting to explain that process - the theories, the search, the discovery, and the ongoing questions.

Eggs are the origins of ninety percent of the Earth's organisms. They can be found as far apart as deep-sea volcanoes and in space. Yet despite their fundamental importance, eggs often find themselves an afterthought in the discussion of evolution of life on Earth as the interests of scientists congregate around the things that emerge from eggs rather than the eggs themselves.

Today, with relatively easy access to our DNA ancestry, we have more data about ourselves and family history than previous generations could have imagined. In the 12 fascinating lessons of Identity in the Age of Ancestral DNA, Anita Foeman, PhD, professor of communication and media, and founder and primary investigator of the DNA Discussion Project at West Chester University, takes us behind the scenes to examine what really happens when individuals receive their personal DNA ancestry results.

In this landmark medical narrative, Pulitzer Prize-winning journalists Mark Johnson and Kathleen Gallagher chronicle the story of Nic Volker, the Wisconsin boy at the center of a daring breakthrough in medicine - a complete gene sequencing to discover the cure for an otherwise undiagnosable illness.

We've all asked ourselves the question. It's impossible to look up at the stars and NOT think about it: Are we alone in the universe? Books, movies, and television shows proliferate that attempt to answer this question and explore it. In Out There, Space.com senior writer Dr. Michael Wall treats that question as merely the beginning, touching off a wild ride of exploration into the final frontier. He considers, for instance, the myriad of questions that would arise once we do discover life beyond Earth (an eventuality which, top NASA officials told Wall, is only drawing closer).

The puzzling lack of evidence for the peculiar but widespread belief that birds have no sense of smell irked evolutionary biologist Danielle Whittaker. Exploring the science behind the myth led her on an unexpected quest investigating mysteries from how juncos win a fight to why cowbirds smell like cookies. In The Secret Perfume of Birds―part science, part intellectual history, and part memoir―Whittaker blends humor, clear writing, and a compelling narrative to describe how scent is important not just for birds but for all animals, including humans.

The language of genes has become common parlance. We know they make your eyes blue, your hair curly or your nose straight. The media tells us that our genes control the risk of cancer, heart disease, alcoholism or Alzheimer's. The cost of DNA sequencing has plummeted from billions of pounds to a few hundred, and gene-based advances in medicine hold huge promise. So we've all heard of genes, but how do they actually work?

Just 45 years ago, the age of gene modification was born. Researchers could create glow-in-the-dark mice, farmyard animals producing drugs in their milk, and vitamin-enhanced rice that could prevent half a million people going blind every year. But now GM is rapidly being supplanted by a new system called CRISPR or "gene editing". Using this approach, scientists can manipulate the genes of almost any organism with a degree of precision, ease and speed that we could only dream of ten years ago.

Did you know women walk more, eat less, socialize more, meet more men, dance more, and flirt more when they're ovulating? Or that PMS may have evolved to get rid of boyfriends with unfit sperm? Behind the "fickle" differences in what women find sexy about men, or what they like to wear, there's a hidden adaptive intelligence shaped over eons. Rather than making women irrational - as the conventional and irredeemably sexist wisdom goes - the female hormonal cycle has been exquisitely fine-tuned to give women the advantages they needed to succeed in our ancestral environments, and perhaps also today.

In this intriguing book, evolutionary biologist Scott Solomon draws on the explosion of discoveries in recent years to examine the future evolution of our species. Combining knowledge of our past with current trends, Solomon offers convincing evidence that evolutionary forces still affect us today. But how will modernization - including longer lifespans, changing diets, global travel, and widespread use of medicine and contraceptives - affect our evolutionary future?

Why are we the way we are? Why do some of us find it impossible to calm a quick temper or to shake anxiety? The debate has always been divided between nature and nurture, but as psychology professor Daniel P. Keating demonstrates in Born Anxious, new DNA science points to a third factor that allows us to inherit both the nature and the nurture of previous generations - with significant consequences.

James T. Costa takes listeners on a journey from Darwin's youth and travels on the HMS Beagle to Down House, his bustling home of 40 years. We accompany Darwin in his myriad pursuits against the backdrop of his enduring marriage, chronic illness, grief at the loss of three children, and joy in scientific revelation. At each chapter's end, Costa shows how we, too, can investigate the wonders of nature at work, with directions on how to re-create Darwin's experiments.

For 100.000 år siden var Jorden beboet af mindst seks menneskearter. I dag er der kun en tilbage: Os. Homo sapiens. Hvorfor endte lige praecis vores art med at herske over kloden? Hvordan kunne vores jaeger- og samlerforfaedre enes om at bygge byer og skabe kongeriger? Hvorfor begyndte vi at tro på guder, nationer og menneskerettigheder? At have tillid til penge, bøger og love? Og vaere slaver af bureaukrati, tidsplaner og forbrugerisme? Og hvordan vil vores verden udvikle sig i det naeste årtusinde?

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

Experts agree on the value of genetic testing when there is a family history of disease, or if the patient has an illness frequently caused by a mutation. Knowing the disease mutation lets family members find out if they have it too and need preventive care. The book explains that doctors can order tests with genetic counseling at relatively low cost and how this will help them prescribe preventive actions, make earlier diagnoses, and get better outcomes.

A list of the attributes that define a mammal is a ragbag of things - fur, live birth, three bones in the middle ear, a brain whose two halves are robustly joined together.... But this curious collection of features contain the roots of all the biology that makes us what we are: monkeys with massive brains who parent extensively, enjoy sport and think lots. Which is to say, what makes us mammals makes us human.
