Female and male brains are different, thanks to hormones coursing through the brain before birth. That’s taught as fact in psychology textbooks, academic journals, and bestselling books. And these hardwired differences explain everything from sexual orientation to gender identity, to why there aren’t more women physicists or more stay-at-home dads. In this compelling book, Rebecca Jordan-Young takes on the evidence that sex differences are hardwired into the brain. Analyzing virtually all published research that supports the claims of “human brain organization theory,” Jordan-Young reveals how often these studies fail the standards of science. Even if careful researchers point out th...
Testosterone is neither the biological essence of manliness nor even the "male sex hormone." It doesn't predict competitiveness or aggressiveness, strength or sex drive. Rebecca Jordan-Young and Katrina Karkazis pry testosterone loose from more than a century of misconceptions that undermine science while making social fables seem scientific.

Going beyond the hype of recent fMRI 'findings', thisinterdisciplinary collection examines such questions as: Do women and men have significantly different brains? Do women empathize, while men systematize? Is there a 'feminine' ethics? What does brain research on intersex conditions tell us about sex and gender?
Here is a brief and authoritative account of human physical growth, beautifully written by one of the world's foremost experts. In Fetus into Man Professor Tanner tells the story of growth in language that is both accessible to the nonbiologist and acceptable to the biologist. The book begins with the basics of growth: cell division, hormonal control and differential growth of body tissues. It then builds on these basics to provide a picture of individual growth--from the fetus in utero to the development of sex differences at puberty. Tanner pays special attention along the way to the psychological and social problems faced by children who mature either too soon or too late, and he concludes with a full description of the major growth disorders and current methods of treatment. Fetus into Man will be an important reference for parents, educators, students of development, and indeed anyone who must deal with the growing child.
Please note: This is a companion version & not the original book. Sample Book Insights: #1 The definition of testosterone is a hormone made in the testes that stimulates the development of male sex organs, secondary sexual traits, and sperm. However, this definition is misleading, because it makes it seem like T is only made by male bodies for male traits. #2 The importance of context is crucial when discussing the singularity of T. T is a multiplicity that exists in bodies, and it is in a constant flow of generation and transformation. It is not just found in sex organs, but everywhere else throughout the body. #3 The first step in the research process is to choose which qualities or behaviors to define aggression. Researchers then have to decide which T to use and how to measure it. T can be extracted from blood, muscle, or other tissues, and it is also found in urine and saliva. #4 The aggression domain is where salivary T has been used the most. It is a good substitute for testosterone in blood, and it is easier to obtain large numbers of people to participate in studies if they don’t need to have blood drawn.
Since World War II, cell biology and molecular biology have worked separately in probing the central question of cancer research. But a new alliance is being forged in the effort to conquer cancer. Drawing on more than 500 classic and recent references, Baserga's work provides the unifying background for this cross-fertilization of ideas.
Winner of a British Medical Association Book Award A Brain Pickings Best Science Book of the Year Early birds and night owls are born, not made. Sleep patterns may be the most obvious manifestation of the highly individualized biological clocks we inherit, but these clocks also regulate bodily functions from digestion to hormone levels to cognition. Living at odds with our internal timepieces, Till Roenneberg shows, can make us chronically sleep deprived and more likely to smoke, gain weight, feel depressed, fall ill, and fail geometry. By understanding and respecting our internal time, we can live better. “Internal Time is a cautionary tale—actually a series of 24 tales, not coincidenta...
In this powerful critique, the esteemed historian and philosopher of science Evelyn Fox Keller addresses the nature-nurture debates, including the persistent disputes regarding the roles played by genes and the environment in determining individual traits and behavior. Keller is interested in both how an oppositional “versus” came to be inserted between nature and nurture, and how the distinction on which that opposition depends, the idea that nature and nurture are separable, came to be taken for granted. How, she asks, did the illusion of a space between nature and nurture become entrenched in our thinking, and why is it so tenacious? Keller reveals that the assumption that the influen...
Sex discrimination is supposedly a distant memory. Yet popular books, magazines and even scientific articles defend inequalities by citing immutable biological differences between the male and female brain. Why are there so few women in science and engineering, so few men in the laundry room? Well, they say, it's our brains.
