New Books in the History of Science

Flowering currant, ivy, Portuguese laurel, and woad might all have grown in a medieval garden, but it would have taken special expertise to extract and create rich blue and purple pigments from them. Humans have been extracting dyes and inks from natural materials for millennia, and the practice was firmly established during the medieval era, recorded in manuscripts that survive today. Gold from Newton's Apple Tree: Historical Recipes for Natural Inks, Paints, and Dyes (Princeton UP, 2026) by Nabil Ali brings together recipes for making natural colors according to season, method, and ingredients.This unique book takes its title from an ink recipe derived from a descendant of Sir Isaac Newton’s apple tree, in which ingredients extracted from the bark are transformed, seemingly by magic, from brown to a yellow gold. But gold pigments can also be extracted from cornflower, crocus, greater celandine, myrrh, and turmeric. Ali shares his own accessible adaptations for preparing these and other recipes rooted in medieval craft traditions. Along the way, he provides an engaging and informative natural history of the plants used, alongside the broad spectrum of marvelous colors they produce.Presenting original translations of medieval recipes taken from painters’ and illuminators’ technical manuscripts from the third century BCE through to the twenty-first century, alongside stunning botanical illustrations, Gold from Newton’s Apple Tree is a captivating celebration of colors derived from nature.

The South American coca plant was established in 19th-century Britain as a medical product before it became a globally restricted drug. Drawing on botanical, economic, pharmaceutical, social, and political perspectives, in Coca and the Victorians: From Botanical Curiosity to Regulated Drug, 1835–1912 (Transcript Publishing, 2025), Dr. Kim Embrey analyses how the use and perception of coca changed as it was transferred to Europe. In a process of cultural dissimilation, coca was not simply adopted, but embedded into new medical, social, and scientific contexts. The study shows how a plant from the Andes was repositioned in British modernity.

In Sex Isn’t Real: The Invention of an Incoherent Binary (Duke UP, 2026), Beans Velocci traces the history of current high stakes attempts to define sex and to create a world devoid of trans life. Drawing on lab notes, family genealogies, medical case studies, and more, Velocci follows scientists and clinicians from the mid-nineteenth through the mid-twentieth century and across five disciplines—zoology, eugenics, gynecology, statistical sexology, and transsexual medicine—as their ideas and practices created a definitional tangle. They demonstrate how the sorting of bodies into male and female persists not despite but because of sex’s incoherence: the defining features of these categories shift to contain various understandings of anatomy and physiology, theories of race, developments in research and medical methodologies, and bodies that cannot be accounted for in a binary framework. Exposing the endless work required to produce a world in which most people have a binary gender identity that neatly fits their binarily sexed body, Velocci demonstrates that it is not cis people who fit the categories; it’s the categories that flex to make them fit.

Beans Velocci is Assistant Professor of History and Sociology of Science and Gender, Sexuality, and Women’s Studies at the University of Pennsylvania.

Europe's Laboratory: Climate and Health in Eighteenth-Century Russia (Cornell UP, 2025) is a history of eighteenth-century naturalists and physicians who were involved in the creation of a classification system for the people of the Russian Empire. These Enlightened scholars traveled through Russia describing its people, landscape, and customs. In an era when climate was seen as a significant factor affecting health and bodies, these men wondered: How did the Russians, a "cold" people—phlegmatic or melancholic, according to humoral theory—manage an empire?

The experiences and observations of doctors and scholars working within the Russian Empire contributed to advances in understanding and/or treating diseases like scurvy, smallpox, and more. Key insights were embedded in the travel writings and correspondences of colorful eighteenth-century figures who Romaniello brings to life with vibrant biographies. Medical knowledge was entangled with stories of culture and imperial politics as well. In Europe's Laboratory, Romaniello’s deft contextualization helps make sense of these intextricable branches of eighteenth-century taxonomies as he demonstrates that the Russian Empire was a part of global knowledge networks.

The Origins of the New (Princeton University Press, 2026) presents a revolutionary approach to evolutionary success in all realms of life. In this groundbreaking book, Douglas Erwin takes readers on a dazzling excursion across science and history to explore how evolution generates new and enduring features in biology, culture, and technology.Erwin begins by tracing how thinkers from Darwin’s time to the present day have sought to discover the driving mechanisms of evolutionary novelty. He then lays out compelling empirical evidence for separating novelty from innovation, showing that novelty involves the emergence of unique characteristics, while innovation concerns the success of those characteristics over time. Erwin develops a unifying conceptual framework for these powerful dynamics, demonstrating how they have shaped everything from the evolution of avian feathers and flight to the creation of human language and the breathtaking advances in digital computing we’re witnessing today.A landmark work that redefines our understanding of the changes happening all around us, The Origins of the New reveals how the forces of novelty and innovation are the same across nature and culture, continually producing new forms and refashioning the world as we know it.

Our guest is doctor Doug Erwin, who is an independent researcher at the Santa Fe Institute, after retiring as Senior Scientist and Curator of Paleobiology at the National Museum of Natural History of the Smithsonian Institution.

Our host is Eleonora Mattiacci, an Associate Professor of Political Science at Amherst College. She is the author of "Volatile States in International Politics" (Oxford University Press, 2023).
