It's not easy for most of us to receive negative feedback. Even when the person delivering that feedback is constructive and reasonable, we often feel the urge to defend ourselves. This week, we look at the psychology of defensiveness with neuroscientist Emily Falk. We'll explore what causes so many of us to resist constructive criticism, and how we can get better at giving and receiving such feedback. Then, in the latest installment of our ongoing series "Your Questions Answered," psychologist Ciara Greene returns to the show to answer your questions about memory and forgetfulness.If you have follow-up questions or thoughts for Emily Falk after listening to today’s conversation, and you’d be willing to share with the Hidden Brain audience, please record a voice memo on your phone and email it to us at ideas@hiddenbrain.org. Use the subject line “mental barriers.” Thanks! Our next stops on the Hidden Brain tour are coming up! Join us in Baltimore on October 11, Washington, D.C. on October 12, or Los Angeles on November 22. And stay tuned for more cities to be added for 2026.

How a group of 80’s Cuban misfits found rock-and-roll and created a revolution within a revolution, going into exile without ever leaving home. Reporter Luis Trelles brings us the story of punk rock’s arrival in Cuba and a small band of outsiders who sentenced themselves to death and set themselves free. We originally released this episode back in 2015 in a collaboration with Radio Ambulante, but the story is so fascinating (and, in many ways, still relevant) that we haven’t stopped thinking about it. Special thanks to the bands VIH, Eskoria, Metamorfosis and Alio Die & Mariolina Zitta for the use of their music. Radio Ambulante launches their 15th season on September 30th!!Check it out, here!!

First up on the podcast, aggressive tumors have a secret cache of DNA that may help them beat current drug treatments. Freelance journalist Elie Dolgin joins host Sarah Crespi to talk about targeting so-called extrachromosomal DNA—little gene-bearing loops of DNA—that help difficult-to-treat cancers break the laws of inheritance.
Next on the show, producer Meagan Cantwell talks with Weidong Sun, director of the Center of Deep Sea Research at the Chinese Academy of Sciences, about the discovery of a hydrogen-rich system so large it makes up at least 5% of current estimates for global hydrogen emissions from abiotic sources. They discuss how hydrogen gas rising from the mantle reacting with oxygen could have triggered an explosion that formed holes hundreds of meters across and dozens of meters deep.

Many of us have been raised to believe that if we want to get something done, we just need to set our minds to it. Where there's a will, there's a way, right? Yet somehow we end up polishing off that pint of ice cream in the freezer, or spending more than our budget allows. It's almost as if we're not the ones in charge. This week, we talk with psychologist and neuroscientist Emily Falk about why our minds often conspire against our best interests, and how we can regain control. Do you have follow-up questions or thoughts for Emily Falk after listening to today’s conversation?

Some people love the structure, others say it wrecks work-life balance - new data from Angus Reid says nearly 50% of Canadians think federal workers should be forced back into the office. Nearly the same number of people disagree. This is after major major banks like BMO and RBC have mandated up to four days a week in-office. Ontario's public service is following suit, with full-time office returns expected by January. Employers say it's about collaboration, creativity and mentorship. But some workers aren't convinced. For them, remote work offers flexibility, autonomy and time with family. Our question: Should employers be able to force workers back into the office? What is lost when we work from home?
Toronto's new renoviction bylaw forces landlords to prove renovations are necessary before evicting tenants. Supporters say it protects renters from being pushed out illegally. Landlords say it's a bureaucratic mess that discourages building upgrades and will ultimately lead to higher rents. But, we're not just focusing on Toronto. Cities across Canada, like New Westminster, B.C., Hamilton and London all have renoviction by-laws in motion or in place. So wherever you are in Canada, this issue may affect you.Our question: Are renoviction bylaws a step too far or not far enough?
In August we performed a live taping of the show from a theater perched on the edge of Manhattan, overlooking the Hudson River, overshadowed by the wide open night sky. Three stories about voids. One about a fish that screams into the night – and the mystery of its counterpart that doesn’t. Another about a group of women who gazed at the night sky and taught us just how vast the universe is. And a third about a man who talk to aliens – and the people who tell him he’s putting human civilization at risk by doing so. Finally, we turn back to Earth with the help of a reading from Samantha Harvey’s hit novel Orbital (https://zpr.io/RNi4sY2JVKxK) performed by the artist, actor and podcast host Helga Davis (https://zpr.io/TKGuzzDFnVjN). What does it mean to stand on the edge of a void, and what happens when you scream into it, or choose not to?This episode was originally produced and developed in front of a live audience by Little Island, Producing Artistic Director Zack Winokur, Executive Director Laura Clement.

Flying in the U.S. is still exceptionally safe, but the system relies on outdated tech and is under tremendous strain. Six experts tell us how it got this way and how it can (maybe) be fixed.

First up on the podcast, despite so many advances in treatment, HIV drugs can suppress the virus but can’t cure the infection. Where does suppressed HIV hide within the body? Staff Writer Jon Cohen joins host Sarah Crespi to talk about the Last Gift Study, in which people with HIV donate their bodies for rapid autopsy to help find the last reservoirs of the virus.
Next on the show, Christine Elliott, a doctoral candidate in the department of entomology at Purdue University, talks about the Bug Bowl—an annual public outreach event that highlights all the wonders and benefits of insects. We also get to hear the sounds of violins trying to be crickets and learn how music connects people to bugs in ways that posters and public lectures can’t.
