In the thirteenth-century Mediterranean, commerce transformed as merchants shifted from Roman to Indo-Arabic numerals—an alternative that better facilitated complex calculations. It has long been known that this transition stemmed from Europe’s increasing exchanges with India, Persia, and the Arabic world. Yet much remains to be understood about how Indo-Arabic numerals—and the practical arithmetic they enabled—actually spread across Europe. As Dr. Raffaele Danna shows in The Craft of Indo-Arabic Numerals: How Practical Arithmetic Shaped Commerce and Mathematics in Western Europe, 1200–1600 (Harvard University Press, 2026), it was hundreds of ordinary merchants, schoolmasters, and artisans who nurtured these changes, thereby driving key advances in both commerce and mathematics.

Drawing on an original catalog of more than 1,200 practical arithmetic manuals, Dr. Danna charts the incremental spread of the new figures with unprecedented precision. While Italian merchants were the early adopters, it took nearly three centuries for Indo-Arabic numerals to become established in northern Europe. As Dr. Danna shows, adoption did not follow the routes of maritime trade. Rather, Indo-Arabic numerals moved gradually across the continent through inland networks of practitioners. Everywhere they went, the ten figures enhanced commercial practices and facilitated the emergence of a coherent language of mathematical craft. The growing social circulation of this knowledge, in turn, had a lasting impact on the economic trajectory of Western Europe. By the late sixteenth century, even academics were absorbing lessons from the vernacular tradition—a development that led to the first major breakthroughs in European mathematical theory since antiquity.

Combining economic history with the social history of mathematics, The Craft of Indo-Arabic Numerals illuminates the integral role of practical arithmetic in both intellectual and commercial transformations across Western Europe.

What makes us who we are?Through the stories of seven of his patients, acclaimed Oxford University neurologist Masud Husain shows us how our brains create, change and can even restore our identity. Husain introduces us to a man who ran out of words, a woman who lost all inhibitions and another who believed she was having an affair with the man who was really her husband.These compelling human dramas reveal how our identities are created by different functions within the brain. It will ignite new ideas about who we really are – and why we act in the ways we do.

For nearly a century, every Democratic president—and many Republicans—entered office promising to restructure America’s health care system. Barack Obama finally broke through but, in the process, opened a tumultuous decade in which battles over health care dominated American politics. In Whiplash: From the Battle for Obamacare to the War on Science (Yale University Press, 2026), Dr. David Blumenthal and Dr. James A. Morone go behind the scenes to describe how three very different presidents—pursuing very different goals—maneuvered through the fraught politics of health care.President Obama ended the century-long quest for reform but ignited a screaming culture war that blazed into the Trump administration and blew up during the COVID epidemic. President Trump, facing the greatest health crisis in a century, denied and dithered. Then he directed a medical triumph in Operation Warp Speed. He and President Biden, facing the pandemic’s devastation, mounted the most successful anti-poverty program in eighty years. But in the tumult, Trump launched a shattering new political war, not over coverage but over science itself.Authoritative and gripping, this book describes the remarkable achievements of these years while also showing how respect for science clashed with scorn toward the deep state and left the nation unprepared for the next health crisis.

Imagine a future where we grow houses rather than build them. Where smartphones are alive, clothing has opinions and all human knowledge fits into a speck of DNA. A world where disease is a thing of the past and the human lifespan is dramatically extended.To achieve this, says Adrian Woolfson, founder of the genome writing company Genyro, we must transform biology into a predictive, programmable engineering material. That means decoding the generative grammar of DNA: the language of life itself. We will then be able to author genomes—and, if we choose, even rewrite our own.In On the Future of Species: Authoring Life by Means of Artificial Biological Intelligence (MIT Press, 2026), Woolfson describes how we are at the cusp of a technological revolution, driven by the convergence of artificial intelligence and synthetic biology. Currently at the scribbling phase—writing the genomes of viruses, bacteria and yeast—we will eventually author the genomes of extinct and never-before-realized species. Life will become computable, detached from its past and no longer bound by Darwinian evolution.While offering extraordinary opportunities, this power also carries great risk, and it is vital for everyone to understand what the future might hold. In this groundbreaking work, Woolfson provides a guide to this bold new world, offering a moral compass to help us do so safely, wisely and ethically.

Adrian Woolfson is the cofounder of Genyro, a California-based biotechnology company specializing in synthetic genome design and construction. He studied medicine at Balliol College, Oxford, and was formerly the Charles and Katherine Darwin Research Fellow at Darwin College, Cambridge, working at the MRC Laboratory of Molecular Biology.

Have you ever wondered what it would be like to watch a double sunset on Tatooine, stand among the sand dunes of Arrakis or gaze at the gas-giant planet Polyphemus from the moon Pandora? In Amazing Worlds of Science Fiction and Science Fact (Reaktion, 2025), Keith Cooper explores the fictional planets of films such as Star Wars, Dune and Avatar, and discusses how realistic they are based on our current scientific understanding and astronomical observations. The real exoplanets astronomers are now discovering are truly stranger than fiction, as the author shows. Featuring insights from over a dozen scientists and award-winning science-fiction authors, including Charlie Jane Anders, Stephen Baxter and Alastair Reynolds, Amazing Worlds of Science Fiction and Science Fact is perfect for readers of popular science and fans of science fiction.
