The Intimate Animal, a new book from Kinsey Institute Executive Director Dr. Justin Garcia

The Science of Sex, Fidelity, and Why We Live and Die for Love

2025-12-16

(Press-News.org) Why do we love who we love? Why do we stay in unfulfilling relationships and stray from rewarding ones? Is it ever a good idea to open a relationship? How has the digital age affected courtship? And why do some longtime couples crash and burn while others stay madly in love? These are just some of the questions Kinsey Institute Executive Director Dr. Justin Garcia explores in his highly anticipated new book, The Intimate Animal.

Drawing on decades of interdisciplinary research in evolutionary biology, psychology, neuroscience, anthropology, and social science, Dr. Garcia reveals the surprising science behind why we crave connection, why relationships can be so complicated, and how intimacy anchors us in the world. With warmth and clarity, his book explains how humans have evolved to need meaningful relationships, while exploring how modern challenges such as digital dating, shifting social norms, and the loneliness epidemic are impacting our ability to connect today.

Blending rigorous science with real-world relevance, The Intimate Animal shows us we are not prisoners of our drives for sex or love. And the more we understand about the science behind our choices, the better equipped we are to build healthy and happy relationships.

Praise for The Intimate Animal

As technology fundamentally shifts how we experience intimacy, Garcia brings us back to the animal inside to remind us that even when connection, love, and desire feel elusive, it’s exactly what we’re wired for.

—Esther Perel, psychotherapist, author of Mating in Captivity and The State of Affairs, and host of Where Should We Begin?

I ABSOLUTELY LOVED THIS BOOK! So exciting to see a research-based book that gets to the real fundamentals in understanding what it means to be human. This book is a real page-turner — so rare in non-fiction.

—Dr. John Gottman, psychologist, co-founder of The Gottman Institute. and author of Fight Right

The Intimate Animal promises to be the best book on modern mating for the next decade. It is scientifically sound, yet conversational in style — highly accessible and informative to everyone. It’s sure to be a smashing success.

—Dr. David M. Buss, evolutionary psychologist and author of The Evolution of Desire: Strategies of Human Mating

This book is a revelation — honest, nuanced, and deeply compassionate. Garcia cuts through noise and shame to map how we bond, break, and begin again.

—Lara Love Hardin, founder of True Literary and author of The Many Lives of Mama Love

A brilliant exploration of why we love, connect, and sometimes stray. …Insightful and eye-opening, The Intimate Animal will make you stop, reflect, and say, ‘Oh, that is why I do that.’ A must-read for anyone curious about the deeper forces behind love, sex, and connection.

When blue-collar workers lose union protection, they try self-employment

2025-12-16

In U.S. states with anti-union labor environments, workers are up to 53% more likely to start their own businesses—and blue-collar workers are more likely to do it out of necessity. A study in Strategic Entrepreneurship Journal examines how the labor environment in states with “right-to-work” (RTW) laws compared with that in neighboring states with stronger union bargaining power. “We found that the enactment of stringent anti-union laws reduces employees’ incentives to stay ...

New video dataset to advance AI for health care

2025-12-16

Researchers at the University of Pennsylvania have launched Observer, the first multimodal medical dataset to capture anonymized, real-time interactions between patients and clinicians. Much like the medical drama The Pitt, which portrays life in the emergency room, Observer lets outsiders peer inside primary care clinics — only, in this case, none of the filmed interactions are fictional. Until now, the data available to health care researchers has been limited to traces left behind after a visit: qualitative information like clinician notes and quantitative measurements like patient vital signs. None of these sources ...

MEA-based graph deviation network for early autism syndrome signatures in human forebrain organoids

2025-12-16

Multi-electrode arrays (MEAs) provide a noninvasive interface with sub-millisecond temporal resolution and long-term, multi-site recordings, enabling mechanistic investigations of in vitro human brain development and disease-related dysfunction; nevertheless, conventional MEA pipelines largely rely on firing/burst statistics or channel-/waveform-level features, which can be insufficient to systematically characterize and interpret network-level organization and its subtle pathological deviations. Accordingly, representing ...

New modeling approach sheds light on rare gut disease

2025-12-16

During development of the digestive system, a complex network of nerves forms around it, creating a “second brain” — the enteric nervous system (ENS) — which controls the movement of food and waste through the gut. But a combination of changes in the molecular letters making up certain genetic instructions can prevent these nerves from developing properly, leading to Hirschsprung disease (HSCR), a painful and often dangerous condition in which babies develop intestinal blockage and are unable to pass stool. A study led by NYU Langone Health researchers reveals a new strategy to ...

Study documents potentially hazardous flame retardants in firefighter gear

2025-12-16

Some firefighter gear is manufactured with chemicals called brominated flame retardants that could pose a risk to firefighter health, according to a new study published in Environmental Science & Technology Letters on Dec. 16. The study is the first published research in the U.S. to investigate and document the use of brominated flame retardants in firefighter turnout gear, worn for protection on the job. The findings could inform fire department decision-making when it comes to keeping or replacing gear. Structural firefighters — those working in the built environment — wear turnout gear consisting of three layers: a flame-resistant outer shell; a ...

Can certain bacteria regulate aging of the immune system and its related alterations?

2025-12-16

The process of aging is associated with a decline in immune functions and persistent low-level inflammation. Now, researchers from Japan have discovered a strain of Lentilactobacillus capable of preventing and even reversing aging-related immune alterations. Feeding aged mice with heat-inactivated YRC2606 resulted in lowered levels of inflammatory cytokines and signaling proteins. These findings point to the possibility of a functional food intervention that has the potential to benefit an increasingly aging population. The health benefits of consuming fermented milk products have been passed down through generations, without clearly understanding ...

AI model helps diagnose often undetected heart disease from simple EKG

2025-12-16

Doctors may soon be able to diagnose an elusive form of heart disease within seconds by using an AI model developed at University of Michigan, according to a recent study. Researchers trained the model to detect coronary microvascular dysfunction, a complex condition that requires advanced imaging techniques to diagnose, using a common electrocardiogram. Their prediction tool significantly outperformed earlier AI models in nearly every diagnostic task, including predicting myocardial flow reserve, the gold standard for ...

There are fewer online trolls than people think

2025-12-16

Americans overestimate online toxicity, believing 43% of Reddit users post severely toxic comments when only 3% actually do, and this misperception inculcates pessimism about society. Angela Y. Lee, Eric Neumann, and colleagues surveyed 1,090 American adults via the online platform CloudResearch Connect to compare people’s perceptions of harmful online behavior with platform-level data from past research. Participants overestimated the prevalence of Reddit users posting toxic content by 13-fold and overestimated the prevalence of Facebook users sharing false news by 5-fold, guessing 47% of users post false news while only 8.5% actually do. Even when participants ...

Cell membrane fluctuations produce electricity

2025-12-16

Researchers develop a theoretical framework that shows how living cell membranes can generate electricity from molecular fluctuations. Pradeep Sharma and colleagues created a model demonstrating that active biological processes, such as protein dynamics and ATP hydrolysis, create membrane fluctuations that could produce transmembrane voltages via flexoelectricity. Such transmembrane voltages can reach 90 millivolts. Voltage changes can happen on millisecond timescales, matching typical action potential curves for neurons. The authors’ framework predicts that active membrane ...

Jeonbuk National University study shows positive parenting can protect adolescents against self-harm

2025-12-16

Self-harm refers to intentionally injuring one’s own body as a coping mechanism to emotional distress. It manifests in many forms and has serious consequences not only on physical health but also on mental health. Self-harm among adolescents is becoming a significant public issue. It is more common in adolescence than any other age group, and adolescent self-harm experiences can increase the likelihood of repeated self-harm, suicide risk, substance use in adulthood, and long-term mental health difficulties. Among ...
