What I Am Reading:
Mitochondria Are More Than Powerhouses - They're the Motherboard of the Cell
Every cell biology class you ever took told you that mitochondria are the powerhouses of the cell. Martin Picard at Columbia argues that framing undersells them by about an order of magnitude. His research shows mitochondria function more like a central nervous system for cellular health: they sense stress, send signals to the nucleus, influence gene expression, and coordinate the body's response to everything from exercise to emotional trauma. The practical implication is that how you treat your body at the level of sleep, stress, and physical activity isn't just affecting your energy levels. It's shaping the intelligence of your cells.
Is the Secret to Men's Longevity a Great Butt?
The Wall Street Journal ran with a headline that sounds like a joke but the underlying research is serious. Glute strength turns out to be one of the strongest predictors of longevity in men, better than most biomarkers most people track obsessively. The mechanism makes sense: the glutes are the largest muscle group in the body, and their strength is a proxy for overall lower body power, metabolic health, and the kind of functional capacity that determines whether you can stay active and independent well into old age. Worth rethinking your training priorities if your current routine doesn't include anything that seriously loads the posterior chain.
What George Clooney Personally Taught Me About Charm
The insight here is deceptively simple: Clooney's charm is not about being interesting, it's about being interested. The way he makes every person in a room feel like the most important person in it is a skill, not a personality trait, and it's learnable. The author watched it happen up close and unpacks why it works: genuine curiosity signals to people that they matter, which creates trust faster than any amount of wit or charisma. Most people are so focused on how they're coming across that they forget the entire game is about making the other person feel seen.
Consciousness is the only truly creative thing in the universe
Oxford philosopher Victoria Trumbull published this piece last week and it's been sitting with me. Her argument: AI can produce outputs that mimic originality, but mimicry and genuine novelty are not the same thing. The creative act, in her view, requires consciousness because it requires the capacity to introduce something genuinely new into a universe otherwise governed by fixed laws. Whether you fully buy the argument or not, it forces a useful question about what we actually mean when we say something is creative, and whether the bar we're applying to AI is the right one.
The most innovative companies in defense tech for 2026
Fast Company's annual ranking of defense tech innovators is worth reading not for the list itself but for the narrative arc it traces. The common thread across the companies that made it is speed: not just technological speed but procurement speed, production speed, and organizational speed. The old defense model was built around decade-long programs and trillion-dollar contractors. What's winning now is the ability to ship something that works in the field within months, not years. Anduril reportedly raising another $4 billion at a $60 billion valuation confirms that investors believe this shift is permanent.
Many minds, not many worlds, constitute quantum reality
The many-worlds interpretation of quantum mechanics is dramatic enough to have entered pop culture, but physicist Nadia Blackshaw makes the case it's also probably wrong. The alternative she defends, called the many-minds interpretation, says that when quantum events occur it's not the universe that branches but the observer's mind. Reality stays singular. The branching is cognitive, not physical. It sounds subtle but the implications for how we think about the relationship between consciousness and the physical world are significant, and this is one of the cleaner explanations of the problem I've come across.
What I Am Listening to:
David Reich: Why the Bronze Age Was an Inflection Point in Human Evolution | Dwarkesh Podcast
Harvard geneticist David Reich just published a paper that overturns a long-standing assumption in evolutionary biology: that natural selection has been mostly dormant in humans since the agricultural revolution. It hasn't. Reich and his collaborators found that selection has been rampant over the last 10,000 years, particularly for immune traits, metabolic traits, and cognitive traits during the Bronze Age. The Dwarkesh conversation unpacks both the science and a genuinely provocative companion idea: that Neanderthals may have been culturally modern humans who interacted with, interbred with, and were eventually absorbed by our ancestors. One of the more mind-expanding episodes I've listened to this year.
BI 235 Romain Brette: The Brain, in Theory | Brain Inspired
Brain Inspired is hosted by Paul Middlebrooks and sits at one of the most underexplored intersections in science right now: neuroscience and artificial intelligence. This episode is a proper challenge to some of the deepest assumptions in both fields. Romain Brette, research director in computational and theoretical neuroscience in Paris, argues that the whole framework neuroscience has borrowed from computer science, notions like representation, computation, coding, prediction, is getting in the way of actually understanding how the brain works. He makes the case using a single-celled organism called the paramecium, which has no neurons at all but navigates and behaves with apparent purpose. The implications for AI are uncomfortable and interesting.
Peptides, Bioregulators, and the Future of Cellular Repair | LONGEVITY with Nathalie Niddam
Nathalie Niddam has been quietly building one of the more technically serious longevity podcasts around. Most health shows stay on the surface. This one goes into bioregulator peptides, senolytics, and the cellular mechanisms that actually govern how fast we age. The episode on mitochondrial health and peptide protocols pairs perfectly with the Martin Picard piece in this month's reading list. If you follow longevity science seriously and you haven't found this show yet, it's worth your time.
What I Am Watching:
Martin Short: Facing Tragedy with Joy
Martin Short has been one of the most reliably funny people in entertainment for over fifty years. This CBS Sunday Morning piece goes into what he's endured privately, including the loss of his wife Nancy to cancer in 2010 and several close friends, and how he has chosen to respond to all of it. His answer is not something you'd frame as a philosophy. It's more of a practice: keep going, stay engaged with the work, don't let grief become your identity. There's something genuinely instructive in watching someone with that much scar tissue still show up every day with that much lightness.
The Hard Problem of Consciousness Explained | Closer to Truth
Robert Lawrence Kuhn runs one of the best long-running series on the intersection of science and philosophy, and this episode cuts straight to the hardest version of the consciousness problem: why does physical processing give rise to subjective experience at all? Not how the brain works, but why anything going on in the brain feels like anything from the inside. The guests here include some of the best thinkers on the subject and the format lets the disagreements surface clearly rather than smoothing them over. This is a good entry point for anyone who hasn't spent time with the hard problem before.
Inside Anduril's Arsenal-1: America's First Autonomous Munitions Factory | CNBC
CNBC got rare access inside Anduril's Arsenal-1 facility in Columbus, Ohio, which is the first factory built from scratch specifically to produce autonomous munitions at industrial scale. The physical infrastructure is genuinely impressive: the building was designed around the production line rather than the other way around, which is the opposite of how most defense manufacturing still works. Watching this alongside the Fast Company defense tech rankings gives you a concrete sense of why the capital is flowing where it is. The companies that solve the manufacturing problem are the ones that define this decade.
