    Could solar energy be the key to unlocking a future free from fossil fuels and extreme poverty? Casey Handmer, founder and CEO of Terraform Industries, believes so. His company is pioneering technology that could revolutionize how we produce and consume energy, potentially solving climate change and global energy inequality in one fell swoop.
    Terraform Industries is developing machines that create synthetic natural gas from sunlight and air. It sounds like science fiction, but the technology is rooted in simple chemistry and powered by the rapidly advancing field of solar energy.
    But Handmer's vision extends beyond just replacing fossil fuels. He sees solar energy as the catalyst for a new era of human progress. By providing cheap, abundant energy to every corner of the globe, we could potentially eliminate extreme poverty within our lifetimes. It's an ambitious goal, but one that Handmer believes we have a responsibility to pursue.

  • How 30 seconds of clarity saved my life | Andrew Zimmern
    What happens when an irredeemable person receives love, gratitude, and respect? After decades of drug and alcohol abuse, chef and television personality Andrew Zimmern learned firsthand.

    As a teenager, Andrew Zimmern experienced deep pain when his mother became permanently disabled, and his father enforced a rule to avoid discussing feelings. Without an outlet, that pain grew into resentment and substance abuse. By 14, Zimmern was drinking daily, and his addiction followed him into adulthood, ultimately costing him his career, relationships, and home.
    In January 1992, after hitting rock bottom, Zimmern attempted to take his own life. When he woke up, something shifted. For the first time, he asked for help. His friends intervened, sending him to rehab, where he began confronting his emotions and embracing a mindset of learning and giving.
    Zimmern rebuilt his life, becoming a celebrated chef, author, and TV personality. Today, he credits that one vulnerable moment with saving his life and inspiring him to live with purpose and gratitude.

  • Are we disciplining ourselves out of happiness? | Oliver Burkeman for Big Think+
    "There will always be too much to do. You're never going to feel completely ready. You're never going to be able to feel confident about what's coming in the future."

    Many of us wake up each morning with something Oliver Burkeman calls “productivity debt.” The bestselling author and journalist explains this term as “a sense that you've got to work really hard during the day to pay off this debt of getting things done. Otherwise, you won't quite feel like you're an adequate and acceptable human being.”
    It's becoming very obvious that this ever-accelerating treadmill of productivity  isn't going to lead to a final, perfect destination There will always be more to do. You're never going to feel completely ready. You're never going to be able to feel confident about what's coming in the future. 
    If you set out on some big project of scheduling your time very, very, very strictly, not only will you probably fail and get very stressed, but even if you succeed, you'll fail in a way because there'll be some lack of spontaneity to that path, a sense of having to carry out these instructions that you've given yourself that is at odds with what we really value from being alive. And so that's why we need a way of understanding and thinking about work and productivity that does not treat getting on top of everything as the goal, explains Burkeman. Here, he lays out four guiding principles to lead a better, more fulfilling life.

  • The surprising data on AI and unemployment rates | Joseph Politano
    “I'm here to argue that AI is not going to cause a rise in unemployment. I think it's actually increased employment in the United States, not decreased it.”

    Up next, How COVID-era monetary policy changed everything ► https://www.youtube.com/watch?v=YEnxt1cf3MI
    When ChatGPT was first rolled out, there was a widespread fear that unemployment was going to rise very quickly. Well, it's been several years since ChatGPT was released, and the unemployment rate in the United States has stayed the same, says Joseph Politano, economic analyst and data journalist.
    In fact, if you look at employment in the U.S., it's near some of the highest levels on record -- and they've only increased over the last few years since the start of the pandemic. The economy has gone through tectonic economic shifts before. Think: the rise of the smartphone, or the rise of the internet, or the rise of the phone in the first place. Or even things as simple as elevator buttons that put elevator operators out of work. These created new jobs that more than replaced the jobs lost by technological change.
    In fact, if you look at data from the U.S. Census Bureau, on one of the most comprehensive surveys of businesses in America, the vast majority of businesses said that AI has not affected their employment levels at all. And if you look at the subset of businesses that said AI affected their employment levels, the majority said that it increased the number of people they had on staff, not decreased. That's not to say that all industries and all occupations are going to be completely unaffected. There's going to be a shift away from the kind of work that AI is able to do exceptionally well, and towards the kind of work that humans can specialize in. Here’s what to expect from the job market with the rise of generative AI.

  • How to detect a scam supplement (3 easy tests) | Dr. Jen Gunter
    “The truth is there are very few supplements that have good evidence-based medicine to support them.”

    Supplements and vitamins constantly go viral with claims that they can transform your health just by integrating these pills into your daily routine. But before you add to cart, take a pause and make sure you’re buying exactly what you think you are. In the US, supplement companies can’t explicitly claim to cure, treat, or prevent a disease. So how can you know which ones are legit, and which ones might just be a money grab?
    Besides being potentially ineffective and a waste of money, some supplements have been shown to contain heavy metal, fungi, or even mold contaminants, and others contain just a fraction of what they claim to.
    OB/GYN and bestselling author Dr. Jen Gunter says that you can easily discern snake oil salesmen from legitimate supplements grounded in good science with these 3 tips.

    About Dr. Jen Gunter:
    I am an OB/GYN and a pain medicine physician. I write a lot about sex, science, and social media, but sometimes I write about other things because, well, why not?
    I’ve been called Twitter’s resident gynecologist, the Internet’s OB/GYN, and one of the fiercest advocates for women’s health. I have devoted my professional life to caring for women.
    I’m here to build a better medical Internet. You can’t be empowered about your health if you have incorrect information. I got interested in online snake oil and dubious science when my own children were born extremely prematurely. I found separating the facts from the fiction difficult and I am a doctor, so I started thinking if this is hard for me how does everyone else manage? It put the bad information that my own patients were bringing into the office in perspective. I know people sit up late at night Googling things and fall down rabbit holes of misinformation because I’ve been there!

  • The secret behind Diana Nyad’s incredible 53-hour swim

    At 64, Diana Nyad swam 110 miles from Cuba to Florida, facing jellyfish, exhaustion, and tough ocean currents for over 53 hours. But this feat was more than just physical - it was the result of a lifetime of mental endurance.
    As a young swimmer, she faced sexual abuse from her coach, which derailed her Olympic dreams and left deep emotional scars. Instead of letting those experiences hold her back, she found a way to channel that pain into something powerful. She talks about developing a "steel trap mind," using her struggles as motivation to pursue her goals.
    Diana's journey goes beyond breaking records. It’s a powerful reminder of the human spirit's ability to persevere and heal, no matter the odds. Her swim from Cuba to Florida, completed on her fifth attempt, showcases her incredible willpower and serves as an inspiration to people everywhere.

  • The illusion of self and the illusion of free will, explained | Annaka Harris
    “Many people get stuck in feeling responsible for their psychological state, and there's a way in which simply being with whatever uncomfortable emotions rather than believing that you are controlling them can be extremely beneficial for psychological wellbeing.”

    Up next, Science is shattering our intuitions about consciousness ► https://www.youtube.com/watch?v=m0UjqT45JsQ
    Are you actually in the driver’s seat of your own life? The illusion of free will says that our choices are determined by factors greater than our intentions and actions, that total conscious control is purely an illusion.
    We may assume that illusions like this have evolved for their usefulness, but most illusions that we experience are actually glitches, says bestselling author Annaka Harris.
    Take for example the illusion of self – the other side of the illusion of free will coin. We think of ourselves as solid, unchanging entities that move through time and space, separate from the rest of the physical world. This illusion confuses us about our place in nature, and the state of our reality.
    Harris explores these two illusions and how they shape our everyday experience.

    As modern humans we experience a different world and experience than anyone who has ever come before us. This is because we've inverted the dynamics of how our lives unfold. We live on a planet defined by local stability, but global instability. The hunter-gatherers that came before us lived in a world that was defined by local instability, but global stability, says political scientist Dr. Brian Klaas.
    As hunter-gatherers, their day-to-day lives in their local environment was unpredictable. Now we have flipped that world. We experience local stability, but global instability. We have extreme regularity in our daily lives. We can order products online and expect exactly when they're going to arrive. We can go to Starbucks anywhere in the world and it's going to taste roughly the same.
    But our world is changing faster than it ever has before. Consequentially, when things do go wrong, the ripple effects are much more profound and much more immediate. This is where that sort of aspect of global instability becomes very dangerous.

  • Prime your mind for disaster — while you’re still in control | Amanda Ripley

    Up next, She studied extreme psychopaths. Here’s what it taught her about human nature ► https://www.youtube.com/watch?v=kyow7KAHDks
    We all have ideas about how we're gonna behave in a crisis or emergency, but it’s almost never how it actually plays out when we’re faced with a disaster situation, says bestselling author Amanda Ripley.
    In fact, you have another personality – a ‘disaster personality’ –, and it's helpful to understand what it is before you are forced to embody it. Studying human behavior in different disasters across history reveals a huge spectrum of responses. Sometimes people start hysterically screaming, others shut down. Some laugh in the face of a life or death situation.
    In Ripley’s book, "The Unthinkable," the author followed people who had survived disasters of all kinds, and found that there's a pattern, even across very different contexts, from plane crashes to earthquakes. Almost always, people go through a period of certain emotions. Do you want to learn how to master your disaster response before facing a crisis? Ripley explains how.
