Over 4.5 billion years, Earth's climate has transformed tremendously. Before our more temperate recent past, the planet swung from one extreme to another--from a greenhouse world of sweltering temperatures and high sea levels to a "snowball earth" in which glaciers reached the equator. During this history, we now know, living things and the climate have always influenced and even shaped each other. But the climate has never changed as rapidly or as drastically as it has since the Industrial Revolution.In The Story of Earth's Climate in 25 Discoveries: How Scientists Found the Connections Between Climate and Life (Columbia University Press, 2024), Donald R. Prothero explores the astonishing connections between climate and life through the ages, telling the remarkable stories of the scientists who made crucial discoveries. Journeying through the intertwined evolution of climate and life, he tackles questions such as: Why do we have phytoplankton to thank for the air we breathe? What kind of climate was necessary for the rise of the dinosaurs--or the mammals, their successors? When and how have climatic changes caused mass extinctions? Prothero concludes with the Ice Ages and the Holocene, the role of climate in human history, and the perils of anthropogenic climate change. Understanding why the climate has changed in the past, this timely book shows, is essential to grasping the gravity of how radically human activity is altering the climate today.

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 unsupportedKostas Kampourakis is the author and editor of several books about evolution, genetics, philosophy and history of science, as well as the editor of the Cambridge University Press book series Understanding Life.

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. Learn more about your ad choices.

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.Dr. Michael LaMagna is the Information Literacy Program & Library Services Coordinator and Professor of Library Services at Delaware County Community College.

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. Learn more about your ad choices.

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. Aims to debunk myths and correct falsehoods about Charles Darwin's life and work Leading Darwin scholars offer new conclusions about the history and nature of science Accessibly written for readers across many fields including history, philosophy and the sciences Kostas Kampourakis is the author and editor of several books about evolution, genetics, philosophy and history of science, as well as the editor of the Cambridge University Press book series Understanding Life.

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.Galina Limorenko is a doctoral candidate in Neuroscience with a focus on biochemistry and molecular biology of neurodegenerative diseases at EPFL in Switzerland.
