“The Painful Truth about Hunger in America” with Professor Mariana Chilton

​

Hunger is far more than the immediate and tangible experience of not being able to find or buy food. While it is true that hunger is often depicted as the physical sensation of an empty stomach—a condition that can be temporarily alleviated by food—the issue runs much deeper. Hunger is more than the absence of food; it is a manifestation of deeper, societal and structural failings leading to individual and collective trauma. To genuinely combat hunger, we must engage with its underlying causes—economic inequality, systemic discrimination, and societal neglect—and strive to create a compassionate and just society where all people have the resources, respect, and opportunities they need to thrive. In her book “The Painful Truth about Hunger in America: Why We Must Unlearn Everything We Think We Know—and Start Again” professor Mariana Chilton presents a bold, transformative perspective on addressing hunger and poverty in the United States. The book emphasises that hunger in the United States is underpinned by profound societal and structural failures that perpetuate poverty and ensure that millions remain trapped in cycles of scarcity. In this episode of Bridging the Gaps I speak with professor Mariana Chilton.

Although the book focuses on the issues of hunger and poverty in the United States, the human experiences and the underlying structural and social root causes it explores are often universal. The insights and key points raised in the book resonate with similar challenges faced in other societies and regions, making its research and findings valuable for broader learning and application.

Mariana Chilton is a Professor of Health Management and Policy at Drexel University’s Dornsife School of Public Health. She is the founder of the Center for Hunger-Free Communities, where she initiated impactful programs such as “Witnesses to Hunger”, aimed at amplifying women’s voices in the national conversation on hunger and poverty, and the “Building Wealth and Health Network”, which focuses on fostering economic security and healing. Chilton has provided expert testimony on hunger solutions before both the US Senate and the House of Representatives.

Our discussion delves into the intricate connections between hunger and trauma, revealing the emotional and psychological toll on individuals and communities. We examine the persistent nature of poverty and its link to generational trauma and explore the complex relationship between poverty, violence, and systemic inequalities. Professor Chilton provides thoughtful explanations supported by real-world examples and personal stories, many of which are detailed in her book. We also discuss challenges involved in conducting research on such sensitive topics, particularly when working with vulnerable populations. The discussion covers both ethical considerations and the logistical obstacles researchers face when collecting data and sharing findings in a manner that respects and empowers participants. Professor Chilton’s insights shed light on the importance of compassionate, inclusive approaches to research and advocacy that prioritise the voices of those most affected by these issues.

“The Network of Life: A New View of Evolution” with Professor David Mindell

The Network of Life: A New View of Evolution on Bridging the Gaps

For a long time, the prevailing perspective on evolution has been that it follows a vertical pathway, where genetic information is passed down from one generation to the next in a linear fashion, resembling a “tree of life.” This classical view suggests that species evolve through a process of divergence from common ancestors, resulting in a branching tree structure that traces the lineage of life over time. In his new book “The Network of Life” Professor David Mindell emphasises the need to update this understanding, and explains that evolution functions more like a distributed, decentralised network. In this framework, there are possibilities for horizontal evolution, where genetic material is shared across species in a more fluid and interconnected manner. The book looks at the forces behind horizontal evolution, such as interbreeding, genetic recombination, merging of species, horizontal gene transfer, and coevolution. The network view of evolution leads to a new symbiotic theory of health. It suggests that the future well-being of humans, other species, and our environment relies on how life evolves and adapts within this interconnected web. In this episode of Bridging the Gaps I speak with Professor David Mindell.

Professor David Mindel is a senior researcher of Zoology at the University of California, Berkeley. He is a former professor of ecology and evolutionary biology at the University of Michigan, director of the University of Michigan Museum of Zoology, and Dean of Science at the California Academy of Sciences.

We begin our discussion by revisiting the traditional concept of vertical evolution, where life is represented as a branching tree. This model shows how species evolve through a series of splits, tracing their lineage back to common ancestors. We explore how this classical framework explains the development of species over time and then shift to discussing two core ideas in evolutionary theory: natural selection and genetic mutation. For much of history, evolution has been viewed primarily through the lens of vertical inheritance, which emphasises the transmission of traits from parent to offspring.

One reason for this focus on vertical evolution is that early evolutionary studies, including Darwin’s, were centred around natural selection, with limited knowledge about genetic mutations. At that time, the role of genetic mutations was not well understood. Today, we know they are essential drivers of evolution. We examine how this early gap in understanding may have shaped the preference for the vertical model of evolution and consider whether it limited perspectives on how species adapt over time.

Next, we delve into the concept of horizontal evolution, which presents a shift from the traditional view. In “The Network of Life”, Professor David Mindell explores evidence suggesting that horizontal evolution—where genes are shared across species—has been happening since life began on Earth. To set the stage, I ask him to outline what we currently know about the origins of life. We also discuss the intriguing role of viruses, which can transfer genetic material between species and influence evolutionary paths.

We then dive into the key discoveries that support and solidify the concept of horizontal evolution. Processes such as hybridization, species merging, and horizontal gene transfer provide strong evidence for this interconnected view of life. Mindell highlights the contributions of prominent scientists and pivotal studies that have reshaped our understanding of evolution.

If we update the current evolutionary framework to include horizontal evolution, what new questions might this approach help us answer? We discuss the significance of adopting this broader perspective and how it could refine our understanding of life’s history.

Finally, we explore the exciting possibilities that arise from this new understanding. By embracing the network view of evolution, we can enhance research on synthetic life, support assisted evolution to help species adapt to climate change, and revolutionise our approaches to biotechnology, medicine, and environmental sustainability. This has been an insightful and enriching conversation, shedding light on the profound impact of horizontal evolution on our world.

“Middle Tech: Software Work and the Culture of Good Enough” with Professor Paula Bialski

Middle Tech on Bridging the Gaps

Contrary to the widespread belief that all technology is sleek, flawless, and cutting-edge, much of it isn’t designed to meet such high standards or be revolutionary. In many environments, the goal isn’t always to create perfect, futuristic products. Instead, the focus is often on functionality—producing tech that is good enough to meet immediate needs without striving for perfection. This mindset contrasts with the image of the tech world as a space of constant innovation, where every new development is expected to disrupt industries and change lives. Instead, in many cases, the aim is to simply keep things running smoothly, making sure the technology works well enough to get by, while knowing that it will likely be improved or replaced in the next version. In her book “Middle Tech: Software Work and the Culture of Good Enough” Professor Paula Bialski explores this idea through an ethnographic study of software developers working at a corporate tech company. In this episode of Bridging the Gaps, I speak with Professor Paula Bialski.

Paula Bialski is associate professor of digital sociology at the University of St. Gallen in St. Gallen, Switzerland.

We begin our discussion by exploring why Paula chose to conduct her study at a mid-sized software development company, rather than focusing on the world’s top tech firms with their sleek offices and cutting-edge facilities. This choice allowed her to investigate a more grounded and realistic aspect of the tech industry. From there, we dive into how she conducted her research—how she embedded herself with the developers and built rapport to understand their day-to-day work and culture.

A major focus of our conversation is the concept of “good enoughness” in corporate software development. Paula explains how this mindset shapes the way tech workers approach their tasks, balancing functionality and time constraints over perfection. I ask her if “good enough” can sometimes become a way to avoid striving for excellence, or even an excuse for sloppiness, which leads us to a broader conversation about how developers navigate this balance.

We also discuss the challenges software engineers face at work, such as dealing with outdated systems, tight deadlines, and corporate expectations, and how these challenges compare to those in other professions. We also touch upon the challenges they face in their personal space. Paula gives insight into how the fast-paced culture of the tech world, where professionals often move quickly from one job to the next, influences the work environment.

Finally, we briefly touch on Paula’s upcoming project, which will examine the impact of AI on software development—a topic that promises to provide new insights into how technology will continue to shape this field. It has been a fascinating conversation that sheds light on a side of the tech industry not often discussed.
