Showing results for "Sex" in Science & Engineering

Statistically speaking, only one out of every one thousand sexual acts between a man and a woman will result in a pregnancy. And, as we know, sex does not solely take place just between men and women. So: what is sex for? In this wide-ranging and powerful new history of sex, Dr Fern Riddell will uncover the sexual lives of our ancestors and show that, just like us, they were as preoccupied with sexual identities, masturbation, foreplay, sex and deviance; facing it with the same confusion, joy and accidental hilarity that we do today.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

There is no one better qualified than Jared Diamond - renowned expert in the fields of physiology and evolutionary biology and award-winning author - to explain the evolutionary forces that operated on our ancestors to make us sexually different. With wit and a wealth of fascinating examples, he explains how our sexuality has been as crucial as our large brains and upright posture in our rise to human status.

In The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity—and will Determine the Fate of the Human Race, George Washington University professor and psychiatrist Daniel Z. Lieberman, MD, and Georgetown University lecturer Michael E. Long present a potentially life-changing proposal: Much of human life has an unconsidered component that explains an array of behaviors previously thought to be unrelated, including why winners cheat, why geniuses often suffer with mental illness, why nearly all diets fail, and more.

In this fascinating and thought-provoking book, author Nick Lane brings together the latest research findings in the exciting field of mitochondria research to reveal how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death.

The brilliant and hugely influential book by the winner of the 2017 Royal Society Insight Investment Science Books Prize. Gender inequalities are increasingly defended by citing hard-wired differences between the male and female brain. That’s why, we’re told, there are so few women in science, so few men in the laundry room - different brains are just suited to different things. 

Between what can be learned from evolutionary psychology and cognitive science a picture emerges. In Sex, Murder, and the Meaning of Life, social psychologist Douglas Kenrick fuses these two fields to create a coherent story of human nature. In his analysis, many ingrained, apparently irrational behaviors—one-night stands, prejudice, conspicuous consumption, even art and religious devotion—are quite explicable and (when desired) avoidable.

What does it mean to be female? Mother, carer, the weaker sex? Think again. In the last few decades a revolution has been brewing in zoology and evolutionary biology. Lucy Cooke introduces us to a riotous cast of animals, and the scientists studying them, that are redefining the female of the species. Meet the female lemurs of Madagascar, our ancient primate cousins that dominate the males of their species physically and politically. Or female albatross couples, hooking up together to raise their chicks in Hawaii.

How much control do we have over love? Much less than we like to think. All that mystery, all that poetry, all those complex behaviors surrounding human bonding leading to the most life-changing decisions we’ll ever make, are unconsciously driven by a few molecules in our brains.

With acuity, humor, and respect for human diversity, The Shortest History of Sex reveals where the many facets of our sexuality—chemical, anatomical, behavioral, social—come from. Chasing down our evolutionary family tree, from the first aquatic creatures to primate societies, David Baker sheds light on our baffling array of passions, impulses, and fetishes, and guides us toward a clear understanding of one of the deepest, most abiding forces of human nature.

First published in 1871, The Descent of Man, and Selection in Relation to Sex sees Darwin apply his evolutionary theory to the human race, controversially placing apes in our family tree. The book covers a range of adjacent themes, including differences between different peoples, the dominance of women in mate choice, and the relevance of evolutionary theory to general society.

Imagine if it was possible to have the perfect sexual relationship without compromise, eat meat without killing animals, have babies without the need to bear them, and choose the time of our painless death. Life would be better, right? All over the globe, people are trying to make this a reality. They want to use technology to solve the thorniest problems of humanity. But what if these ‘problems’ are the very things that make us human?

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).

Thad Roberts, a fellow in a prestigious NASA program had an idea - a romantic, albeit crazy, idea. He wanted to give his girlfriend the moon. Literally. Thad convinced his girlfriend and another female accomplice, both NASA interns, to break into an impregnable laboratory at NASA's headquarters—past security checkpoints, an electronically-locked door with cipher security codes and camera-lined hallways—and help him steal the most precious objects in the world: the moon rocks.

Written in a brilliantly engaging style by biologist Jules Howard, this fascinating and highly engaging work covers the how and why of sex on Earth, in all its diversity. From sperm wars to cuckoldry, hermaphrodites and virgin births, spent males, racy harems, clitoral births, hips, breasts and birdsong, penis-percussion, and those riskiest and most elusive of all traits, monogamy and true love, all this and more is discussed in Sex on Earth, as Jules takes us on a voyage of discovery of the ins and outs of animal reproduction.

In the movies, robots can be terrifying. In reality, thinking machines are disrupting the world in ways that are even more disturbing than in Hollywood fantasies - but they also have the potential to change our lives for the better. In this stirring, visionary work, acclaimed roboticist Dr. Ayanna Howard explores how the tech world’s racial and sexual biases are infecting the next generation of Artificial Intelligence, with profoundly negative effects for humans of all genders and races.

Humans are the only mammals to walk on two, rather than four, legs. From an evolutionary perspective, this is an illogical development, as it slows us down. But here we are, suggesting there must have been something tremendous to gain from bipedalism. First Steps takes our ordinary, everyday walking experience and reveals how unusual and extraordinary it truly is. The seven-million-year-long journey through the origins of upright walking shows how it was in fact a gateway to many of the other attributes that make us human.

There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness.

With acuity, humor, and respect for human diversity, The Shortest History of Sex reveals where the many facets of our sexuality—chemical, anatomical, behavioral, social—come from. Chasing down our evolutionary family tree, from the first aquatic creatures to primate societies, David Baker sheds light on our baffling array of passions, impulses, and fetishes, and guides us toward a clear understanding of one of the deepest, most abiding forces of human nature.

We inherit mechanisms for survival from our primeval past - none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: It changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world.
