Over the last several decades, manufacturing jobs in the U.S. have withered. Meanwhile, health care has become the fastest growing job sector in the country, and it’s been on top for years. According to Gabriel Winant, a historian at the University of Chicago, and author of “The Next Shift: The Fall of Industry and the Rise of Health Care in Rust Belt America,” not only are those two opposing trends related, but there are also some serious consequences to the connection.

From Mathew Brady’s Civil War photographs, to some of the first images of Earth in space, photography has shaped the way we see ourselves. Which means that when photographic technology changes and progresses, it can really shift our self-image. Ainissa Ramirez is a scientist and the author of The Alchemy of Us: How Humans and Matter Transformed One Another, and she was previously on Innovation Hub to talk about how materials science altered the way we think about time. Now, she tells the fascinating story of how people shaped photographs and how those photographs then shaped us. And that story begins with an incredibly rich man betting on horses.

Money is “a social agreement,” according to Frederick Kaufman, a journalism professor at the City University of New York. You and the cashier both agree that a $20 bill — a green piece of paper that any baby or dog wouldn’t hesitate to tear to shreds — is worth something, and this consensus imbues the bill with value. Eventually, babies get on board, as they’re taught the value humans have long ascribed to different types of currency; a value that’s socially constructed, but so deeply ingrained in our society that it feels silly to question.

This consensus has led Kaufman to crown money “the most powerful metaphor.” In his new book, The Money Plot, Kaufman unravels the myth-making that has underpinned financial transactions from bartering to bitcoin.

Do you have memories from adolescence you’d rather forget? Previously, that choice — whether to open up that embarrassing high school yearbook or keep it firmly closed — generally rested in your hands. But for kids growing up in today’s social media landscape, the digital footprint they (or their parents) create can immortalize childhood and its growing pains forever.

Kate Eichhorn, a professor of culture and media at The New School and author of The End of Forgetting, has researched how the permanence of social media chips away at our “agency over traces of the past.” What happens when a digital record won’t allow you to forget? Or when the digital breadcrumbs we create as minors are interpreted as an unshakable portrait of who we are in adulthood? According to Eichhorn, there can sometimes be painful consequences when young people grow up.

When you have a really good idea, copycats may try to steal it for themselves — and that’s what investigators assumed was happening when an unfamiliar man was spotted in a cornfield in Iowa in 2011. They knew that companies like Monsanto were using those fields to grow new types of corn seeds, and that the company was notoriously tight-lipped about the trade secrets behind its crops; farmers didn’t even necessarily know what was being grown on their land. That secretiveness was not without good reason, though. The man in the cornfield, Robert Mo, was indeed trying to smuggle corn seed to China, as a form of intellectual property theft.

Mara Hvistendahl, investigative reporter for The Intercept, and author of The Scientist and the Spy: A True Story of China, the FBI, and Industrial Espionage unpacks the story and explores the wide world of international idea-pilfering: from corn seeds to look-alike cars. According to Hvistendahl, in this war of confidential information, countries like China are notorious for creating knockoffs and bootlegs, while countries like the United States are deeply invested in keeping the secrets behind the originals just that — secret.

How much democracy is too much? Societies have been toying with different democratic models — from how often to hold elections, to who gets to vote and what the public can vote on — for centuries. Garett Jones, an economist and former Senate staffer, argues the current setup in the U.S. desperately needs some tinkering.

Jones says the ancient Greeks, who granted brief political mandates and gave some citizens direct input on law, would be shocked by our modern American politics: “you’re letting people have power for six years?” But he believes our retreat from direct democracy has been positive, and that there’s still further to go. In his latest book, 10% Less Democracy: Why You Should Trust Elites A Little More and The Masses a Little Less, Jones argues that embracing expertise and lengthening congressional terms would make for better politics and more “courageous” politicians.

Last year, many American cities were shut down for long periods during the coronavirus pandemic. They were also the backdrop for widespread demonstrations against racial injustice, in response to the death of George Floyd. As the Biden administration now plots out a road to recovery, with a massive infrastructure plan, Toni Griffin’s work designing cities and spaces focused on equity and inclusion could be more relevant than ever.

Griffin, the founder of Urban American City, professor in Practice of Urban Planning and the director of the Just City Lab at Harvard Graduate School of Design, explains the long and painful legacy of discrimination in urban planning and architecture in America and what it will take to overcome it.

There was a moment in early 2020 when life narrowed and the grocery store became a lifeline — in more ways than one. It was the source of breakfast, lunch and dinner, of course. But those lines emerging from sliding glass doors and wrapping around the block? For a while, they were as close to a social life as we could get, one of our last connections to the outside world. And, when certain items were in short supply in the early days of the pandemic, we were forced to think a lot more about where our food comes from.

The importance of the supermarket is no mystery to Benjamin Lorr, author of “The Secret Life of Groceries: The Dark Miracle of the American Supermarket,” and John Mackey, CEO and co-founder of Whole Foods and author of "Conscious Leadership: Elevating Humanity Through Business." From their general store origins in the 19th century to the vast supply chains we see today, grocery stores have played a hugely influential role in our society — becoming “as American as jazz or the t-shirt,” Lorr says. But, as he explains, there is also a dark side to our brightly-lit food aisles and a cost to our endless options and two-for-one deals.

Our brains are incredibly nimble pieces of machinery, and are actively being rewired and rewritten in response to experience. According to David Eagleman, a neuroscientist at Stanford University, the physical impact of this rewiring is so drastic that imaging is capable of distinguishing the motor cortex of a violinist from that of a pianist.

Eagleman is the author of the book Livewired: The Inside Story of the Ever-Changing Brain, and he walks us through how our daily habits – and forces including social feedback, shifting relevance, and curiosity – can reshape our phenomenally flexible and hardy brains.

Policymakers have a thumb on the scale when it comes to how long we live. Jennifer Karas Montez, a sociologist and demographer at Syracuse University, has spent her career studying the social causes of death and disease in the United States - how differing state policies have contributed to a 7 year gap between the state with the highest (Hawaii) and the lowest (West Virginia) life expectancy in the U.S.

Though COVID-19 has shined a light on how different state approaches to health affect day-to-day life, even in non-pandemic times, longevity and health are deeply impacted by what’s going on at the state level. From how generous paid leave is where you live, to how easy marijuiana is to access, the patchwork of policies across the U.S affect health outcomes.
