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.

A.I. Revolution
Can we harness the power of artificial intelligence to solve the world’s most challenging problems without creating an uncontrollable force that ultimately destroys us? ChatGPT and other new A.I. tools can now answer complex questions, write essays, and generate realistic-looking images in a matter of seconds. They can even pass a lawyer’s bar exam. Should we celebrate? Or worry? Or both? Correspondent Miles O’Brien investigates how researchers are trying to transform the world using A.I., hunting for big solutions in fields from medicine to climate change.
AI can restore the middle-class jobs lost to automation
AI is indeed changing the labor market, see the flood of news articles on layoffs happening in part due to companies’ priorities shifting to AI. Now a new working paper from Massachusetts Institute of Technology economist David Autor says that the shift presents a unique opportunity: AI could enable more workers to perform higher-stakes, decision-making tasks that are currently relegated to highly-educated workers such as doctors and lawyers.
