All of us would like to live longer, or to slow the debilitating effects of age. In How We Age: The Science of Longevity (Princeton UP, 2023), Coleen Murphy shows how recent research on longevity and aging may be bringing us closer to this goal. Murphy, a leading scholar of aging, explains that the study of model systems, particularly simple invertebrate animals, combined with breakthroughs in genomic methods, have allowed scientists to probe the molecular mechanisms of longevity and aging. Understanding the fundamental biological rules that govern aging in model systems provides clues about how we might slow human aging, which could lead in turn to new therapeutics and treatments for age-related disease.Among other vivid examples, Murphy describes research that shows how changing a single gene in the nematode worm C. elegans doubles its lifespan, extending not only the end of life but also the youthful, healthy part of life. Drawing on work in her own lab as well as other recent research, Murphy chronicles the history and current state of the field, explaining longevity's links to reproduction and mating, sensory and cognitive function, inheritances from our ancestors, and the gut microbiome. Written with clarity and wit, How We Age provides a guide to the science: what we know about aging, how we know what we know, and what we can do with this new knowledge.

In In the Herbarium: The Hidden World of Collecting and Preserving Plants (Yale University Press, 2023), Maura C. Flannery elucidates how herbaria illuminate the past and future of plant science. Collections of preserved plant specimens, known as herbaria, have existed for nearly five centuries. These pressed and labeled plants have been essential resources for scientists, allowing them to describe and differentiate species and to document and research plant changes and biodiversity over time--including changes related to climate. Flannery tells the history of herbaria, from the earliest collections belonging to such advocates of the technique as sixteenth-century botanist Luca Ghini, to the collections of poets, politicians, and painters, and to the digitization of these precious specimens today. She charts the growth of herbaria during the Age of Exploration, the development of classification systems to organize the collections, and herbaria's indispensable role in the tracking of climate change and molecular evolution. Herbaria also have historical, aesthetic, cultural, and ethnobotanical value--these preserved plants can be linked to the Indigenous peoples who used them, the collectors who sought them out, and the scientists who studied them. This book testifies to the central role of herbaria in the history of plant study and to their continued value, not only to biologists but to entirely new users as well: gardeners, artists, students, and citizen-scientists.Hallel Yadin is an archivist and special projects manager at the YIVO Institute for Jewish Research.

What is meaning? How does it arise? Where is it found in the world? In recent years, philosophers and scientists have answered these questions in different ways. Some see meaning as a uniquely human achievement, others extend it to trees, microbes, and even to the bonding of DNA and RNA molecules. In this groundbreaking book, Gary Tomlinson defines a middle path. Combining emergent thinking about evolution, new research on animal behaviors, and theories of information and signs, he tracks meaning far out into the animal world. At the same time he discerns limits to its scope and identifies innumerable life forms, including many animals and all other organisms, that make no meanings at all.Tomlinson’s map of meaning starts from signs, the fundamental units of reference or aboutness. Where signs are at work they shape meaning-laden lifeways, offering possibilities for distinctive organism/niche interactions and sometimes leading to technology and culture. The emergence of meaning does not, however, monopolize complexity in the living world. Countless organisms generate awe-inspiring behavioral intricacies without meaning. The Machines of Evolution and the Scope of Meaning (Zone Books, 2023) offers a revaluation of both meaning and meaninglessness, uncovering a foundational difference in animal solutions to the hard problem of life.”Nathan Smith is a PhD Student in Music Theory at Yale University (nathan.smith@yale.edu).

Should your doctor prescribe a placebo for you, instead of conventional medicine? And if she did, would it work? Is the double-blind placebo-controlled paradigm really the gold standard for medical research?Placebos are the most widely used treatments in the history of medicine. Thousands of studies show that they can be effective and make us happier and healthier. Yet confusion about what placebos are and how to measure their effects prevents some doctors from using them to help patients. Meanwhile, damage caused by the nocebo effect—the negative effect of expecting something bad—is not widely recognized.In The Power of Placebos: Unlocking Their Potential to Improve Health Care (Johns Hopkins UP, 2023), Jeremy Howick provides an interdisciplinary perspective on placebos and nocebos based on more than twenty years of research and data from over 300,000 patients. This book, the culmination of that research, offers practical ways for researchers, policymakers, and practitioners to put placebo and nocebo research into practice to improve health outcomes.In addition to providing an overview of placebos and nocebos and explaining how belief systems and context can create physiological effects in the body, Howick advocates for a number of controversial positions, including why it may be unethical to include placebos in most clinical trials in which there are already established therapies and why physicians should consider using placebos regularly in their practices. Howick also underscores the importance of the therapeutic effects of interactions between health care practitioners and patients, in the context of care. The Power of Placebos dispels the confusion surrounding placebos and paves the way for doctors to help patients by enhancing placebo effects and avoiding the pitfalls of nocebos.Renee Garfinkel, Ph.D. is a psychologist, writer, Middle East television commentator and host of The New Books Network’s Van Leer Jerusalem Series on Ideas.

During the Last Ice Age, Europe was a cold, dry place teeming with mammoths, woolly rhinoceroses, reindeer, bison, cave bears, cave hyenas, and cave lions. It was also the home of people physically indistinguishable from humans today, commonly known as the Cro-Magnons. Our knowledge of them comes from either their skeletons or the tools, art, and debris they left behind.Cro-Magnon: The Story of the Last Ice Age People of Europe (Columbia UP, 2023) tells the story of these dynamic and resilient people in light of recent scientific advances. Trenton Holliday-a paleoanthropologist who has studied the Cro-Magnons for decades-explores questions such as: Where and when did anatomically modern humans first emerge? When did they reach Europe, and via what routes? How extensive or frequent were their interactions with Neandertals? What did Cro-Magnons look like? What did they eat, and how did they acquire their food? What can we learn about their lives from studying their skeletons? How did they deal with the glacial cold? What does their art tell us about them?Holliday offers new insights into these ancient people from anthropological, archaeological, genetic, and geological perspectives. He also considers how the Cro-Magnons responded to Earth's postglacial warming almost 12,000 years ago, showing that how they dealt with climate change holds valuable lessons for us as we negotiate life on a rapidly warming planet.Melek Firat Altay is a neuroscientist, biologist and musician.
