    Why did Isaac Newton read books on chiromancy, the occult science of hand reading that revealed the secrets of the soul? Why did Charles Darwin claim that the hand gave humans dominion over all other species? Why did psychoanalyst Charlotte Wolff climb into the primate cages of the London Zoo, taking hundreds of delicate palm prints? Why did Francis Galton, the father of fingerprinting, take palm prints too? And why did world-leading geneticists study the geometry of palm lines in their search for the secrets of chromosomal syndromes? Decoding the Hand: A History of Science, Medicine, and Magic (University of Chicago, 2025) is an astounding history of magic, medicine, and science, of an enduring search for how our bodily surfaces might reveal an inner self—a soul, a character, an identity. From sixteenth-century occult physicians influenced by the Kabbalah to twentieth-century geneticists, and from criminologists to eugenicists, award-winning historian Dr. Alison Bashford takes us on a remarkable journey into the strange world of hand readers, revealing how signs on the hand—its shape, lines, marks, and patterns—have been elaborately decoded over the centuries. Sometimes learned, sometimes outrageously deceptive, sometimes earnest, and, more often than we ever expected, medically and scientifically trained, these palm readers of the past prove to be essential links in the human quest to peer into bodies, souls, minds, and selves. Not only for fortune-telling palmists were the future and the past, health, and character laid bare in the hand, but for other experts in bodies and minds as well: anatomists, psychiatrists, embryologists, primatologists, evolutionary biologists, geneticists, and more. Drawing telling parallels between the divination promised by palmistry and the appeal to self-knowledge offered by modern genetic testing, Decoding the Hand also makes clear that palm-reading is far from a relic or simple charlatanism. Dr. Bashford’s sagacious history of human hands touching and connecting opens wide the essential human pursuit of what lies within and beyond. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

  • Kenneth Aizawa, "Compositional Abduction and Scientific Interpretation: A Granular Approach" (Cambridge UP, 2025)

    Kenneth Aizawa, "Compositional Abduction and Scientific Interpretation: A Granular Approach" (Cambridge UP, 2025)
    Jan 10 2026
    How do scientists reason when they posit unobservables to explain their observed results? For example, how did Watson and Crick reason that DNA had a double-helix structure when they observed Franklin’s image 51, or how did Hodgkin and Huxley reason that sodium ions carried the current flowing into the membrane of a voltage-clamped giant squid axon? In Compositional Abduction and Scientific Interpretation: A granular approach (Cambridge University Press), Kenneth Aizawa argues for an account of such reasoning as singular compositional abduction: explaining particular experimental results in terms of lower-level entities, such as the bonds between nucleotides or the positive charges of sodium ions. Aizawa, who is professor of philosophy at Rutgers University—Newark, draws on close examination of scientific practice to argue that dominant views in philosophy of science regarding abduction do not capture what scientists are actually doing. Instead, he articulates compositional abduction as a specific form of inferential practice in science distinct from eliminating alternative hypotheses, employing hypothetical-deductive confirmation, or identifying mechanism components.

    Heino Falcke and Jörg Römer, "Light in the Darkness: Black Holes, the Universe, and Us" (HarperCollins, 2021)
    Jan 9 2026
    An astrophysicist chronicles his quest to photograph a black hole and reflects on its spiritual ramifications in this international-bestselling memoir. On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference—a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke's goal in making a black hole "visible" for the first time, he recognizes that the photo itself asks more questions for humanity than it answers.Light in the Darkness takes us on Falcke's extraordinary journey to the darkest corners of the universe. From the first humans looking up at the night sky to modern astrophysics, from the study of black holes to the still-unsolved mysteries of the universe, Falcke asks, in even the greatest triumphs of science, is there room for doubts, faith, and a God? A plea for curiosity and humility, Light in the Darkness sees one of the great minds shaping the world today as he ponders the big, pressing questions that present themselves when we look up at the stars.

    Marc Berman, "Nature and the Mind: The Science of How Nature Improves Cognitive, Physical, and Social Well-Being" (Simon and Schuster, 2025)
    Jan 8 2026
    Dr. Marc Berman, the pioneering creator of the field of environmental neuroscience, has discovered the surprising connection between mind, body, and environment, with a special emphasis on the natural environment. He has devoted his life to studying it. If you sometimes feel drained, distracted, or depressed, Dr. Berman has identified the elements of a “nature prescription” that can boost your energy, sharpen your focus, change your mood, and improve your mental and physical health. He also reveals how central attention is to all of these functions, and how interactions with nature can restore it. Nature and the Mind is both an introduction to a revolutionary new scientific field and a helpful guide to better living. In these pages, he draws on his original research and research from others and shares life-altering findings such as:-Just eleven more trees on your street can decrease cardio-metabolic disorders like stroke, diabetes, and heart disease.-A short walk in nature can improve attention by almost twenty percent, decrease depression symptoms, and make people feel more spiritual and self-reflective.-More greenspace around schools and homes is related to better school performance, reduced crime, and improved working memory.-Many of these effects can be achieved even if you don’t like nature.With an engaging and approachable style, Dr. Berman offers the nature prescription for physical health, mental health, and social health. Importantly, you don’t have to pack up your house and move to the country to participate. The nature prescription includes practical ways to bring the outside indoors and to “naturize” our spaces, no matter where you live. The positive effects of nature don’t just end at the individual; contact with nature can make people more caring towards one another, encourage people to care more for the environment, and more.This groundbreaking guide explains why and how nature is good for our brains and bodies and gives us a window into fundamental aspects of our psychology and physiology that can be improved through interactions with nature.

  • Alexa Hagerty, "Still Life with Bones: Genocide, Forensics, and What Remains" (Crown, 2023)

    Alexa Hagerty, "Still Life with Bones: Genocide, Forensics, and What Remains" (Crown, 2023)
    Jan 6 2026
    In Still Life with Bones: Genocide, Forensics, and What Remains (Crown, 2023), anthropologist Alexa Hagerty learns to see the dead body with a forensic eye. She examines bones for marks of torture and fatal wounds—hands bound by rope, machete cuts—and also for signs of identity: how life shapes us down to the bone. A weaver is recognized from the tiny bones of the toes, molded by kneeling before a loom; a girl is identified alongside her pet dog. In the tenderness of understanding these bones, forensics not only offers proof of mass atrocity but also tells the story of each life lost. Working with forensic teams at mass grave sites and in labs, Hagerty discovers how bones bear witness to crimes against humanity and how exhumation can bring families meaning after unimaginable loss. She also comes to see how cutting-edge science can act as ritual—a way of caring for the dead with symbolic force that can repair societies torn apart by violence. Weaving together powerful stories about investigative breakthroughs, histories of violence and resistance, and her own forensic coming-of-age, Hagerty crafts a moving portrait of the living and the dead. Kelly McFall is Professor of History and Director of the Honors Program at Newman University. Learn more about your ad choices.

    Kevin J. Mitchell, "Free Agents: How Evolution Gave Us Free Will" (Princeton UP, 2023)
    Jan 1 2026
    Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency--or free will--is an illusion. In Free Agents: How Evolution Gave Us Free Will (Princeton UP, 2023), leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose. Traversing billions of years of evolution, Mitchell tells the remarkable story of how living beings capable of choice arose from lifeless matter. He explains how the emergence of nervous systems provided a means to learn about the world, granting sentient animals the capacity to model, predict, and simulate. Mitchell reveals how these faculties reached their peak in humans with our abilities to imagine and to be introspective, to reason in the moment, and to shape our possible futures through the exercise of our individual agency. Mitchell's argument has important implications--for how we understand decision making, for how our individual agency can be enhanced or infringed, for how we think about collective agency in the face of global crises, and for how we consider the limitations and future of artificial intelligence. An astonishing journey of discovery, Free Agents offers a new framework for understanding how, across a billion years of Earth history, life evolved the power to choose, and why it matters.

    James Welsh et al., "Weathering Space" (American Scientist 114:1 2026)
    Dec 31 2025
    Past human space missions were protected by Earth’s magnetic field and a measure of luck, but future missions beyond the Earth–Moon system will face far greater and longer-lasting radiation risks that cannot be managed by route planning alone. The authors argue that safe deep-space exploration will require major advances in understanding radiation, developing effective shielding, and mitigating both acute and long-term health effects, rather than relying on chance.

    Jeremiah Joven Joaquin and James Franklin eds., "The Necessities Underlying Reality: Connecting Philosophy of Mathematics, Ethics and Probability" (Bloomsbury, 2025)
    Dec 24 2025
    The Necessities Underlying Reality: Connecting Philosophy of Mathematics, Ethics and Probability (Bloomsbury, 2025) is an open access book that covers four decades of work by the leading Australian philosopher, mathematician and historian of ideas, James Franklin.These interlinking essays are connected by a core theme: the necessary structures in reality that allow certain knowledge of absolute truths. Franklin's Aristotelian realist philosophy of mathematics shows how mathematical truths are directly about physical reality, and at the same time certainly and provably true. Ranging from mathematics to evidence evaluation to ethics, his philosophy of probability sees the relation of evidence to hypothesis, such as in science and law, as purely logical, hence necessary.Across ethics and the philosophy of religion, the theme of necessity is repeated: basic ethical truths (such as the worth of persons and the wrongness of murder) are shown to have the same certainty as mathematics. Focus on the history of ideas connects the philosophical work in the present with the medieval scholastic tradition, which defended similar necessities but is now neglected.Here is an up-to-date introduction to Franklin's overall perspective. Recalling Western philosophy to its roots, it reveals the way absolute necessities are discoverable across the abstract fields of mathematics, logical evidence and ethics.
