The Faustian bargain—in which an individual or group collaborates with an evil entity in order to obtain knowledge, power, or material gain—is perhaps best exemplified by the alliance between world-renowned human geneticists and the Nazi state. Under the swastika, German scientists descended into the moral abyss, perpetrating heinous medical crimes at Auschwitz and at euthanasia hospitals. But why did biomedical researchers accept such a bargain?

The Nazi Symbiosis offers a nuanced account of the myriad ways human heredity and Nazi politics reinforced each other before and during the Third Reich. Exploring the ethical and professional consequences for the scientists involved as well as the political ramifications for Nazi racial policies, Sheila Faith Weiss places genetics and eugenics in their larger international context. In questioning whether the motives that propelled German geneticists were different from the compromises that researchers from other countries and eras face, Weiss extends her argument into our modern moment, as we confront the promises and perils of genomic medicine today.

Burnout is common among doctors in the West, so one might assume that a medical career in Malawi, one of the poorest countries in the world, would place far greater strain on the idealism that drives many doctors. But, as A Heart for the Work makes clear, Malawian medical students learn to confront poverty creatively, experiencing fatigue and frustration but also joy and commitment on their way to becoming physicians. The first ethnography of medical training in the global South, Claire L. Wendland’s book is a moving and perceptive look at medicine in a world where the transnational movement of people and ideas creates both devastation and possibility.

Wendland, a physician anthropologist, conducted extensive interviews and worked in wards, clinics, and operating theaters alongside the student doctors whose stories she relates. From the relative calm of Malawi’s College of Medicine to the turbulence of training at hospitals with gravely ill patients and dramatically inadequate supplies, staff, and technology, Wendland’s work reveals the way these young doctors engage the contradictions of their circumstances, shedding new light on debates about the effects of medical training, the impact of traditional healing, and the purposes of medicine.

Fireworks are synonymous with celebration in the twenty-first century. But pyrotechnics—in the form of rockets, crackers, wheels, and bombs—have exploded in sparks and noise to delight audiences in Europe ever since the Renaissance. Here, Simon Werrett shows that, far from being only a means of entertainment, fireworks helped foster advances in natural philosophy, chemistry, mathematics, and many other branches of the sciences.

Fireworks brings to vibrant life the many artful practices of pyrotechnicians, as well as the elegant compositions of the architects, poets, painters, and musicians they inspired. At the same time, it uncovers the dynamic relationships that developed between the many artists and scientists who produced pyrotechnics. In so doing, the book demonstrates the critical role that pyrotechnics played in the development of physics, astronomy, chemistry and physiology, meteorology, and electrical science. Richly illustrated and drawing on a wide range of new sources, Fireworks takes readers back to a world where pyrotechnics were both divine and magical and reveals for the first time their vital contribution to the modernization of European ideas.

In Banquet at Delmonico’s, Barry Werth draws readers inside the circle of intellectuals, scientists, politicians, businessmen, and clergymen who brought Charles Darwin’s controversial ideas to post-Civil-War America. Each chapter is dedicated to a crucial intellectual encounter, culminating with an exclusive farewell dinner held in English philosopher Herbert Spencer’s honor at the venerable New York restaurant Delmonico’s in 1882. In this thought-provoking and nuanced account, Werth firmly situates social Darwinism in the context of the Gilded Age. Banquet at Delmonico’s is social history at its finest.

How does a so-called bad neighborhood go about changing its reputation? Is it simply a matter of improving material conditions or picking the savviest marketing strategy? What kind of role can or should the arts play in that process? Does gentrification always entail a betrayal of a neighborhood’s roots? Tackling these questions and offering a fresh take on the dynamics of urban revitalization, The Philadelphia Barrio examines one neighborhood’s fight to erase the stigma of devastation.

Frederick F. Wherry shows how, in the predominantly Latino neighborhood of Centro de Oro, entrepreneurs and community leaders forged connections between local businesses and cultural institutions to rebrand a place once nicknamed the Badlands. Artists and performers negotiated with government organizations and national foundations, Wherry reveals, and took to local galleries, stages, storefronts, and street parades in a concerted, canny effort to reanimate the spirit of their neighborhood.

Complicating our notions of neighborhood change by exploring the ways the process is driven by local residents, The Philadelphia Barrio presents a nuanced look at how city dwellers can make commercial interests serve the local culture, rather than exploit it.

Since the 1960s, yoga has become a billion-dollar industry in the West, attracting housewives and hipsters, New Agers and the old-aged. But our modern conception of yoga derives much from nineteenth-century European spirituality, and the true story of yoga’s origins in South Asia is far richer, stranger, and more entertaining than most of us realize.

To uncover this history, David Gordon White focuses on yoga’s practitioners. Combing through millennia of South Asia’s vast and diverse literature, he discovers that yogis are usually portrayed as wonder-workers or sorcerers who use their dangerous supernatural abilities—which can include raising the dead, possession, and levitation—to acquire power, wealth, and sexual gratification. As White shows, even those yogis who aren’t downright villainous bear little resemblance to Western assumptions about them. At turns rollicking and sophisticated, Sinister Yogis tears down the image of yogis as detached, contemplative teachers, finally placing them in their proper context.
