Recent social and political psychological research indicates that increased access to ancestry testing has strengthened the notion of genetic essentialism among some groups, or the idea that our biology ties us to particular ethnic identities. This can boost a sense of cultural pride and prosocial behaviors among communities that are perceived to be similar. In the worst-case scenarios, however, this phenomenon can contribute to deeper social woes like misinformation, anti-science agendas, and even social hatred among those who believe in racial superiority.
Using research from both the social sciences and the genetics literature as support, Ancestry Reimagined: Dismantling the Myth of Genetic Ethnicities (Oxford University Press, 2023) establishes realistic expectations about what we can learn from our DNA as a foundation for examining the psychological impact of ancestry testing, including the differences between how this information is perceived versus its reality. With this book, Dr. Kampourakis flexes his muscles as an esteemed interdisciplinary science educator and author to challenge these traditional social constructs, using the current genetic testing science as a myth busting tool.
Kampourakis argues that DNA ancestry testing cannot reveal a person's true ethnic identity because ethnic groups are socially and culturally constructed. In 10 accessible chapters, he explains the assumptions underlying the scientific study of ancestry, and the resulting paradoxes that are often overlooked. What the study of human DNA mostly shows is that human DNA variation is continuous, and it is not possible to clearly delimit ethnic groups based on DNA data. As a result, we all are members of a huge, extended family, and not of genetically distinct ethnic groups. What ancestry tests can provide are probabilistic estimations of similarities between the test-takers and particular reference populations. This does not devalue the results of these tests, however, because they can indeed provide some valuable information to people who may not know much about their ancestors. In fact, what the tests are very good at doing is finding close relatives, and this is perhaps why the whole enterprise should be rebranded as family, not ancestry, testing. Ultimately, this book reveals that genetic essentialism, biological ethnic identities, racial superiority, and similar social constructs are scientifically unsupported

Francisco Aboitiz is a professor at the Medical School and the director of the Interdisciplinary Center for Neuroscience at Pontificia Universidad Católica de Chile. A History of Bodies, Brains, and Minds: The Evolution of Life and Consciousness (MIT Press, 2024) tells the story of life and nervous systems. It introduces the conceptual framework and terminology of evolution, gives a great overview of our current knowledge and a thorough discussion of open questions.
The first part defines two basic concepts: evolution and life. Surprisingly, we learn that the first definition is more straightforward. If you are challenged by some terminology in the later chapters - like phylogeny, ontogeny, or the different types of homology - it is highly recommended to revisit the definitions in the first chapter.
The story begins in the second part. Chapter 3 introduces multiple theories on how the first cells might have appeared. In the next chapter, these cells start to form more complex, multicellular organisms. Chapter 5 is dedicated to the main characteristics and early history of neurons.
In the third part, we get acquinted with more complex animals. In chapter 6 with the bilaterians, in chapter 7 and 8 with the vertebrates and their nervous system, in chapter 9 with mammals. Chapter 10 provides a deep dive into the neocortex and its role in cognition.
The fourth part of the book is about "a singular ape". Chapter 11 describes the history of primates, focusing on Hominins. It goes into details on various aspects like walking, the growth of brains, toolmaking, and social life. Chapter 12 describes the evolution of vocal communication. Chapter 13 discusses how speech has influenced communication and social life. Chapter 14 explores numerous open questions around consciousness. How to define it? When and how did it emerge in evolution? Which animals are conscious and in which ways? After this long history, chapter 15 arrives in the present and the future. What are some current evolutionary trends? How do cultural and technological changes influence our nervous systems?
In our conversation with Professor Aboitiz, we focused on a few remarkable milestones in this story. For start, he outlined some theories how life might have begun.
Then a huge jump in time followed: How the first mammals appeared and survived in a world dominated by dinosaurs. Professor Aboitiz elaborated on how the brains of mammals differ from the brains of other vertebrates. He described the cerebral cortex, a new part in the mammalian brain. The role of senses changed significantly: The early mammals had worse vision, but better smell, touch, and audition compared to other vertebrates. Changes in the anatomy of the head and neck supported these more developed senses. The enhanced olfactory system is also related to the hippocampus, where some new skills appeared: advanced spatial orientation and short-term memory.
The next milestone we discussed in detail is the appearance of language. Professor Aboitiz shared some fascinating facts about the vocal communication of birds and primates. He explained the connection between toolmaking and language. He described the speech loop and the connection between working memory and talking. He proposes that manual gestures and vocal communication have evolved together, and communication has always been multi-modal.
The last part of our conversation focused on the current and future situation. How culture and technology has changed our nervous system, e.g. how a brain area is particularly involved in reading. Professor Aboitiz also discussed the more recent technological innovations and their effects on society and the environment. He introduced the social projects conducted by the Interdisciplinary Center for Neuroscience. The project RIEN (Robótica Integral Educativa & Neurociencia) facilitates workshops where kids work in teams with rotating roles to build and program robots.

Why the world needs less AI and better programming languages. Decades ago, we believed that robots and computers would take over all the boring jobs and drudgery, leaving humans to a life of leisure. This hasn’t happened. Instead, humans are still doing boring jobs, and even worse, AI researchers have built technology that is creative, self-aware, and emotional—doing the tasks humans were supposed to enjoy. How did we get here?
In Moral Codes: Designing Alternatives to AI (MIT Press, 2024), Alan Blackwell argues that there is a fundamental flaw in the research agenda of AI. What humanity needs, Blackwell argues, is better ways to tell computers what we want them to do, with new and better programming languages: More Open Representations, Access to Learning, and Control Over Digital Expression, in other words, MORAL CODE. Blackwell draws on his deep experiences as a programming language designer—which he has been doing since 1983—to unpack fundamental principles of interaction design and explain their technical relationship to ideas of creativity and fairness. Taking aim at software that constrains our conversations with strict word counts or infantilizes human interaction with likes and emojis, Blackwell shows how to design software that is better—not more efficient or more profitable, but better for society and better for all people. Covering recent research and the latest smart tools, Blackwell offers rich design principles for a better kind of software—and a better kind of world.
Alan F. Blackwell is Professor of Interdisciplinary Design in the Cambridge University department of Computer Science and Technology. He is a Fellow of Darwin College Cambridge, cofounder with David Good of the Crucible Network for Research in Interdisciplinary Design, and with David and Lara Allen the Global Challenges strategic research initiative of the University of Cambridge.

There are many routes to mental well-being. In this groundbreaking book, neuroscientist Camilla Nord offers a fascinating tour of the scientific developments that are revolutionising the way we think about mental health, showing why and how events--and treatments--can affect people in such different ways.
In The Balanced Brain: The Science of Mental Health (Princeton UP, 2024), Nord explains how our brain constructs our sense of mental health--actively striving to maintain balance in response to our changing circumstances. While a mentally healthy brain deals well with life's turbulence, poor mental health results when the brain struggles with disruption. But just what is the brain trying to balance? Nord describes the foundations of mental health in the brain--from the neurobiology of pleasure, pain and desire to the role of mood-mediating chemicals like dopamine, serotonin and opioids. She then pivots to interventions, revealing how antidepressants, placebos and even recreational drugs work; how psychotherapy changes brain chemistry; and how the brain and body interact to make us feel physically (as well as mentally) healthy. Along the way, Nord explains how the seemingly small things we use to lift our moods--a piece of chocolate, a walk, a chat with a friend--work on the same pathways in our brains as the latest treatments for mental health disorders.
Understanding the cause of poor mental health is one of the crucial questions of our time. But the answer is unique to each of us, and it requires finding what helps our brains rebalance and thrive. With so many factors at play, there are more possibilities for recovery and resilience than we might think.

Today I talked to Al Posamentier about his books (co-authored with Christian Speitzer) The Mathematics of Everyday Life (Prometheus Books, 2018). We all are told – practically from the moment we enter school – that mathematics is important because it permeates practically all aspects of our lives. But, for the most part, we don’t really notice it except for those moments, such as when we balance a checkbook, that we know we’re doing mathematics. This book, which requires nothing more than high-school math, is a wonderful way to see that mathematics really is all around us, in our home, in our workplace, in the entertainments we enjoy, and in the world we live in.

Many historical figures have their lives and works shrouded in myth, both in life and long after their deaths. Charles Darwin (1809–82) is no exception to this phenomenon and his hero-worship has become an accepted narrative.
Darwin Mythology: Debunking Myths, Correcting Falsehoods (Cambridge UP, 2024) unpacks this narrative to rehumanize Darwin's story and establish what it meant to be a 'genius' in the Victorian context. Leading Darwin scholars have come together to argue that, far from being a lonely genius in an ivory tower, Darwin had fortune, diligence and – crucially – community behind him. The aims of this essential work are twofold. First, to set the historical record straight, debunking the most pervasive myths and correcting falsehoods. Second, to provide a deeper understanding of the nature of science itself, relevant to historians, scientists and the public alike.

Our universe might appear chaotic, but deep down it's simply a myriad of rules working independently to create patterns of action, force, and consequence. In Ten Patterns That Explain the Universe (MIT Press, 2021), Brian Clegg explores the phenomena that make up the very fabric of our world by examining ten essential sequenced systems. From diagrams that show the deep relationships between space and time to the quantum behaviors that rule the way that matter and light interact, Clegg shows how these patterns provide a unique view of the physical world and its fundamental workings.
Guiding readers on a tour of our world and the universe beyond, Clegg describes the cosmic microwave background, sometimes called the "echo of the big bang," and how it offers clues to the universe's beginnings; the diagrams that illustrate Einstein's revelation of the intertwined nature of space and time; the particle trail patterns revealed by the Large Hadron Collider and other accelerators; and the simple-looking patterns that predict quantum behavior (and decorated Richard Feynman's van). Clegg explains how the periodic table reflects the underlying pattern of the configuration of atoms, discusses the power of the number line, demonstrates the explanatory uses of tree diagrams, and more.

Listen to this interview of Bram Adams, Professor at the School of Computing, Queen's University, Canada. We talk about current developments in peer review, as it is practised in software engineering research.
Bram Adams : "As an editor, one thing you want to see in a review is a summary that clearly says, 'Okay, my overall scoring is this, and my reasons for that are (a) these few negative points but also (b) these few positive points.' But that, in my experience, is missing from reviews much more often than before. Now it is common for editors to get very long and detailed reviews — very well done, in fact — but the major turning-point-reasons for the reviewer’s final recommendation are really spread all throughout the review. And the problem here is that the editor is now put in the difficult position of having to sift through and to locate and in the end really interpret so that those reasons can be made clear to the authors but also to the presiding editor too.”

Peoples & Things host, Lee Vinsel, talks to Cyrus Mody, Professor in the History of Science, Technology, and Innovation and Director of the STS Program at Maastricht University, about his book, The Squares: US Physical and Engineering Scientists in the Long 1970s (MIT Press, 2022). Many narratives about contemporary technologies, especially digital computing and the Internet, focus on the influences of 1960s counter-cultures. In _The Squares_, Mody takes the opposite approach and asks how square, non-counter-cultural scientists and engineers reacted to their changing environments in the 1970s. Vinsel and Mody also talk about what this story may suggest about current efforts to refocus STEM education on “values.” The pair also discuss how, over the course of his career, Mody has continually used a set of historical actors he knows a great deal about to examine different historical themes and questions. Finally, they discuss Mody’s current projects and where he is headed.

Psychologists and neuroscientists struggle with how best to interpret human motivation and decision making. The assumption is that below a mental “surface” of conscious awareness lies a deep and complex set of inner beliefs, values, and desires that govern our thoughts, ideas, and actions, and that to know this depth is to know ourselves. In the The Mind Is Flat: The Remarkable Shallowness of the Improvising Brain (Yale UP, 2019), behavioural scientist Nick Chater contends just the opposite: rather than being the plaything of unconscious currents, the brain generates behaviors in the moment based entirely on our past experiences. Engaging the reader with eye-opening experiments and visual examples, Chater first demolishes our intuitive sense of how our mind works, then argues for a positive interpretation of the brain as a ceaseless and creative improviser.
Dr. Nick Chater is Professor of behavioral science at the Warwick Business School and cofounder of Decision Technology Ltd. He has contributed to more than two hundred articles and book chapters and is author, co-author, or co-editor of fourteen books.
Dr. John Griffiths (@neurodidact) is an Assistant Professor at the University of Toronto, and Head of Whole Brain Modelling at the CAMH Krembil Centre for Neuroinformatics.

Butterflies have long captivated the imagination of humans, from naturalists to children to poets. Indeed it would be hard to imagine a world without butterflies. And yet their populations are declining at an alarming rate, to the extent that even the seemingly ubiquitous Monarch could conceivably go the way of the Passenger Pigeon. Many other, more obscure, butterfly species are already perilously close to extinction. For the last 20 years, Nick Haddad has worked to identify and save some of the rarest butterflies on earth, a quest that has taken him to both surprisingly ordinary and extraordinarily inhospitable areas, including a swampy, active artillery range on a military installation in North Carolina. It has also led him to some surprising conclusions about the best ways to protect these increasingly endangered butterflies.
In The Last Butterflies: A Scientist’s Quest to Save a Rare and Vanishing Creature (Princeton UP, 2019), Haddad profiles five such species – the ones he has determined to be the rarest of all – and takes us into each one’s unique habitat, life cycle, and existential challenges. From the Crystal Skipper, bouncing over sand dunes adjacent to vacation homes on barrier islands, to the Schaus’ Swallowtail, confined to increasingly remote areas of the Florida Keys, Haddad shows how human activities have affected rare butterfly populations. His unexpected conclusion is that leaving them in peace is not a viable option; disturbances, both natural and human-caused, are necessary for the ecosystems that support butterfly populations to thrive. One of the hardest lessons for him to absorb was that to save populations, some individuals have to be killed in the process.
Haddad’s intrepid field work – he describes one of his strengths as “an unusual capacity to tolerate harsh environments - informs the story of each butterfly species. His lab’s effort to collect, quantify, propagate, and ultimately perpetuate, the rarest butterflies has led to increasing awareness of how much more biologists have to learn about their natural histories, and how critical such knowledge is to saving them. In perhaps the most dramatic example of unintended consequences, Haddad’s team discovered that the St. Francis Satyr, a small brown butterfly, was protected by regular artillery fire on the Fort Bragg army installation in southern North Carolina. The resulting fires were one disturbance the St. Francis Satyr needed to sustain viable conditions (dams built by beavers was another). In another twist, it turned out that Haddad’s initial efforts to help the species were having the opposite effect. Yet over time, these discoveries led to lessons that ultimately have helped the St. Francis Satyr and can be applied to other conservation efforts.
The Last Butterflies could be read as a warning, but Haddad’s tone is never dire. The book is infused with enthusiasm for conservation efforts, both now and in the future, and with an admiration for the beauty, fragility, and resilience of butterflies. It is an important book for anyone concerned with biodiversity and conservation issues. It’s also an eye-opening and engaging read for anyone with an interest in butterflies.
Rachel Pagones is chair of the doctoral program in acupuncture and Chinese medicine at Pacific College of Health and Science in San Diego. She is a longtime butterfly enthusiast and is working, slowly, on a fictional book for middle-grade readers about butterfly conservation.

Do newborns think-do they know that 'three' is greater than 'two'? Do they prefer 'right' to 'wrong'? What about emotions--do newborns recognize happiness or anger? If they do, then how are our inborn thoughts and feelings encoded in our bodies? Could they persist after we die? Going all the way back to ancient Greece, human nature and the mind-body link are the topics of age-old scholarly debates. But laypeople also have strong opinions about such matters. Most people believe, for example, that newborn babies don't know the difference between right and wrong-such knowledge, they insist, can only be learned. For emotions, they presume the opposite-that our capacity to feel fear, for example, is both inborn and embodied. These beliefs are stories we tell ourselves about what we know and who we are. They reflect and influence our understanding of ourselves and others and they guide every aspect of our lives. In a twist that could have come out of a Greek tragedy, Berent proposes that our errors are our fate. These mistakes emanate from the very principles that make our minds tick: our blindness to human nature is rooted in human nature itself.
An intellectual journey that draws on philosophy, anthropology, linguistics, cognitive science, and Berent's own cutting-edge research, The Blind Storyteller: How We Reason about Human Nature (Oxford UP, 2020) grapples with a host of provocative questions, from why we are so infatuated with our brains to what happens when we die. The end result is a startling new perspective on our humanity.

On Task: How Our Brain Gets Things Done (Princeton UP, 2020) is a look at the extraordinary ways the brain turns thoughts into actions—and how this shapes our everyday lives.
Why is it hard to text and drive at the same time? How do you resist eating that extra piece of cake? Why does staring at a tax form feel mentally exhausting? Why can your child expertly fix the computer and yet still forget to put on a coat? From making a cup of coffee to buying a house to changing the world around them, humans are uniquely able to execute necessary actions. How do we do it? Or in other words, how do our brains get things done?
In On Task, cognitive neuroscientist David Badre presents the first authoritative introduction to the neuroscience of cognitive control—the remarkable ways that our brains devise sophisticated actions to achieve our goals. We barely notice this routine part of our lives. Yet, cognitive control, also known as executive function, is an astonishing phenomenon that has a profound impact on our well-being. Drawing on cutting-edge research, vivid clinical case studies, and examples from daily life, Badre sheds light on the evolution and inner workings of cognitive control. He examines issues from multitasking and willpower to habitual errors and bad decision making, as well as what happens as our brains develop in childhood and change as we age—and what happens when cognitive control breaks down. Ultimately, Badre shows that cognitive control affects just about everything we do. A revelatory look at how billions of neurons collectively translate abstract ideas into concrete plans, On Task offers an eye-opening investigation into the brain’s critical role in human behavior.

There is no shortage of books on the growing impact of data collection and analysis on our societies, our cultures, and our everyday lives. David Hand's new book Dark Data: Why What You Don't Know Matters (Princeton University Press, 2020) is unique in this genre for its focus on those data that aren't collected or don't get analyzed. More than an introduction to missingness and how to account for it, this book proposes that the whole of data analysis can benefit from a "dark data" perspective—that is, careful consideration of not only what is seen but what is unseen. David assembles wide-ranging examples, from the histories of science and finance to his own research and consultancy, to show how this perspective can shed new light on concepts as classical as random sampling and survey design and as cutting-edge as machine learning and the measurement of honesty. I expect the book to inspire the same enjoyment and reflection in general readers as it is sure to in statisticians and other data analysts.

Einstein’s Dreams (Vintage, 1992) by Alan Lightman, set in Albert Einstein’s “miracle year” of 1905, is a novel about the cultural interconnection of time, relativity and life. As the young genius creates his theory of relativity, in a series of dreams, he imagines other worlds, each with a different conceptualization of time. In one, time is circular, and people are destined to repeat triumphs and failures over and over. In another, time stands still. In yet another, time is a nightingale, trapped by a bell jar.
Translated into over thirty languages, Einstein’s Dreams has inspired playwrights, dancers, musicians and artists around the world. In poetic vignettes, Alan Lightman explores the connections between science and art, creativity and the rhythms of life, and ultimately the fragility of human existence.
This conversation includes Alan Lightman (MIT), Jeffrey Herlihy-Mera and Annette Martínez-Iñesta, of the Departamento de Humanidades at the Universidad de Puerto Rico-Mayagüez (UPRM), and Joshua Chaparro Mata, a UPRM graduate and doctoral student in Applied Physics at Yale. They discuss dreaming as a scientific and creative resource; the importance of Berne, Switzerland, in the thought of Einstein and Lightman; Lightman’s precise and harmonious poetics; the role of technology in contemporary life; and the course Lightman’s life, experiences and creative process.
This is the second of two episodes about Einstein’s Dreams. The first, in Spanish, appeared on the New Books Network en español. The series is sponsored by the Lenguaje focal group at Instituto Nuevos Horizontes at UPRM, a group of scholars who consider how translanguaging can provide unique dimensions to knowledge.
This episode and the Instituto Nuevos Horizontes at the UPRM have been supported by the Mellon Foundation. The conversation is part of the “STEM to STEAM” project of the “Cornerstone” initiative, sponsored by the Teagle Foundation, which stresses the importance of integrating humanistic perspectives in the sciences.

On the surface of the Sun, spots appear and fade in a predictable cycle, like a great clock in the sky. In medieval Russia, China, and Korea, monks and court astronomers recorded the appearance of these dark shapes, interpreting them as omens of things to come. In Western Europe, by contrast, where a cosmology originating with Aristotle prevailed, the Sun was regarded as part of the unchanging celestial realm, and it took observations through telescopes by Galileo and others to establish the reality of solar imperfections. In the nineteenth century, amateur astronomers discovered that sunspots ebb and flow about every eleven years—spurring speculation about their influence on the weather and even the stock market.
Exploring these and many other crucial developments, Pierre Sokolsky provides a history of knowledge of the Sun through the lens of sunspots and the solar cycle. He ranges widely across cultures and throughout history, from the earliest recorded observations of sunspots in Chinese annals to satellites orbiting the Sun today, and from worship of the Sun as a deity in ancient times to present-day scientific understandings of stars and their magnetic fields. Considering how various thinkers sought to solve the puzzle of sunspots, Sokolsky sheds new light on key discoveries and the people who made them, as well as their historical and cultural contexts. Fast-paced, comprehensive, and learned, Clock in the Sun: How We Came to Understand Our Nearest Star (Columbia UP, 2024) shows readers our closest star from many new angles.

A probing examination of the dynamic history of predictive methods and values in science and engineering that helps us better understand today's cultures of prediction.
The ability to make reliable predictions based on robust and replicable methods is a defining feature of the scientific endeavor, allowing engineers to determine whether a building will stand up or where a cannonball will strike. Cultures of Prediction: How Engineering and Science Evolve with Mathematical Tools (MIT Press, 2024), which bridges history and philosophy, uncovers the dynamic history of prediction in science and engineering over four centuries. Ann Johnson and Johannes Lenhard identify four different cultures, or modes, of prediction in the history of science and engineering: rational, empirical, iterative-numerical, and exploratory-iterative. They show how all four develop together and interact with one another while emphasizing that mathematization is not a single unitary process but one that has taken many forms.
The story is not one of the triumph of abstract mathematics or technology but of how different modes of prediction, complementary concepts of mathematization, and technology coevolved, building what the authors call “cultures of prediction.” The first part of the book examines prediction from early modernity up to the computer age. The second part probes computer-related cultures of prediction, which focus on making things and testing their performance, often in computer simulations. This new orientation challenges basic tenets of the philosophy of science, in which scientific theories and models are predominantly seen as explanatory rather than predictive.
