Bloodstains provide clues as to how a crime had been committed. When a speck of blood falls on a surface, it leaves a shape and stain. This is called bloodstain evidence. Each individual carries DNA that is unique to him or her, except for identical twins. With the help of bloodstains and saliva, as well as fingernails, an investigator can recover enough evidence to confirm whether a defendant is guilty or innocent of a crime. This book includes sidebars that further expand on the topic, as well as a further reading list and career information for readers interested in this intriguing STEM field.

In Immeasurable Weather Sara J. Grossman explores how environmental data collection has been central to the larger project of settler colonialism in the United States. She draws on an extensive archive of historical and meteorological data spanning two centuries to show how American scientific institutions used information about the weather to establish and reinforce the foundations of a white patriarchal settler society. Grossman outlines the relationship between climate data and state power in key moments in the history of American weather science, from the nineteenth-century public data-gathering practices of settler farmers and teachers and the automation of weather data during the Dust Bowl to the role of meteorological satellites in data science’s integration into the militarized state. Throughout, Grossman shows that weather science reproduced the natural world as something to be measured, owned, and exploited. This data gathering, she contends, gave coherence to a national weather project and to a notion of the nation itself, demonstrating that weather science’s impact cannot be reduced to a set of quantifiable phenomena.

`Sara Delamont eloquently explores the impact of feminism on sociology and powerfully argues that it has been marginalised. A "must read" for all sociologists searching for a complete account of the development of the discipline′ - Emma Wincup, School of Social Policy, Sociology and Social Research, University of Kent at Canterbury `This is a model of what a textbook should be, for Delamont states what she intends to do, does it with clarity, summarises succinctly and provides interesting and pertinent references′ - Sociological Research Online This book explores the achievements of British feminist sociology in theory, methods and empirical research. It outlines the barriers to the development of feminism and explores contemporary challenges. It provides an unrivalled guide to the origins of feminism in the discipline of sociology, analyses the uneasy relationships between feminists and the founding fathers and elucidates the opportunities and challenges presented by post-modernism. The book was written in the spirit of trying to be even-handed in its discussion of the various schools of feminism. It draws on a variety of empirical areas, from science to stratification and from healths and illness to the professions to illustrate the depth and vitality of feminist perspectives.

Grateful American Book Prize Book of Honorable Mention As a teenager, Mary Edwards Walker determined she would no longer wear the confining corsets and long skirts society dictated women wear at the time and instead opted for pants with a short skirt, setting the stage for her lifelong controversial efforts to change expectations. One of the first women to earn a degree in medicine, Walker championed women’s rights, social justice, and access to health care. She became a Civil War surgeon and a spy, who was captured and arrested by the Confederacy, and she is still the only woman to have been awarded the Medal of Honor. Written by young adult author Sara Latta, I Could Not Do Otherwise teaches readers about Walker’s determination and strength of conviction, as well as her complete disregard of what others thought of her unconventional style. The slogan, “women’s rights are human rights” is a direct descendent of Walker’s words: “The recognition of the individuality of woman, is simply an acknowledgement of human rights, which all human beings have guaranteed them, by the fact of their having an existence.” I Could Not Do Otherwise brings to light an amazing historical figure who broke gender norms and fought for issues that are still relevant today.

Everyone knows what it is to be afraid. But phobias take the normal (and even helpful!) human emotion of fear to a much more visceral, even primal, place. For some people, it’s a spider that does it. For others it’s a clown, or a trans-Atlantic flight, or even just a puddle of water. It’s the thing that stops us in our tracks, sets our hearts racing, and stands our hairs on end. Scared Stiff takes readers on a journey through these experiences—using biology, psychology, and history (not to mention pop culture) to explain where our phobias came from, how they affect us, and how we might eventually overcome them.
