With breathtaking complexity and haunting beauty, the songs of whales have long fascinated scientists. Whales are the only mammals that can sing continuously for ten hours or more, changing the unique songs they sing every year. In Why Whales Sing (JHU Press, 2025), bioacoustician and cognitive scientist Eduardo Mercado transforms our understanding of these enigmatic sounds and proposes a groundbreaking theory that challenges decades of established science.
Fifty years of field research have led most scientists to conclude that humpback whales sing for the same reason that birds do: to advertise their sexual fitness. But if whale songs are nothing more than tools of attraction, why do whales sing even when they're alone and there are no listeners nearby? In light of modern advances in neuroscience and ocean acoustics, Mercado reaches the surprising conclusion that whales may not actually be "singing," but rather engaging in an activity more commonly associated with dolphins and bats--echolocating--which enables them to see their world with sound. By incessantly streaming sounds while listening closely to the returning echoes, whales may be actively tuning their brains in ways that allow them to monitor the movements of silent whales located miles away.
Sophisticated, long-range sonar can enable whales to perceive their vast underwater worlds in unimaginable ways. From the military origins of whale song recordings to the persistent mysteries of cetacean communication, this book displays the wonder of whales and reshapes how we view their intelligence, behavior, and acoustic mastery.

Embodied Intelligence: Multidisciplinary Perspectives on Natural, Artificial, and Hybrid Systems (MIT Press, 2026) explores a radical transformation taking place in intelligence research. Rather than focusing exclusively on brains and computer code, the book examines the important role that embodiment plays in producing intelligent, goal-directed behavior.
Once dismissed as unscientific, psychoanalytic therapy is proving to be among our most effective medical treatments of any kind - outperforming psychiatric drugs and rivaling vaccines in its power to prevent and heal. Why does it work so well?Perhaps because one of the most controversial figures in psychology was right all along. Neuroscience now confirms much of what Sigmund Freud conjectured over a century ago: our deepest struggles stem, not from chemical imbalances, but from buried memories and unconscious conflicts that no pill can touch.Using enthralling case studies and cutting-edge brain science, pioneering neuroscientist Mark Solms makes the case that psychoanalysis should resume its position as our master theory of the mind. Yet modern research also reveals where Freud got important things wrong. Could correcting these errors make therapy even more effective?As psychiatric diagnoses soar and standard treatments continue to fail many patients, The Only Cure: Freud and the Neuroscience of Mental Healing (Pegasus, 2026) offers a revolutionary hope: a real science of healing, rooted in the radical idea that our suffering arises from truths we haven't yet faced.

Today I’m speaking with neuroscientist Stave Ramirez about bullshit and memory. Steve is an associate professor at Boston University, where he runs a lab dedicated to uncovering the mysteries of memory. How memory works, and importantly, how it doesn’t, are crucial questions for understanding everything from the validity of eyewitness testimony to understanding how people overcome traumatic experiences. While the science on memory is far from settled, researchers like Steve are pushing the frontiers of the field forward to better understand how memories are created, stored, and altered. If we can better understand how memory works, we will be better able to understand ourselves. To help us avoid the pitfalls of the bullshit that surrounds the science of memory, I’m pleased to speak with Steve Ramirez.
