Aug 1, 2025 Michael Le Page, a reporter for New Scientist, joins to discuss groundbreaking topics. Weight-loss drugs Ozempic and Wegovy show promise in reversing biological aging—participants in trials experienced a surprising drop in their biological age. Le Page also reveals the creation of a synthetic bacterium with 101,000 genomic alterations, potentially revolutionizing genetic engineering. Finally, he provides insights into the recent rare earthquake off Russia's coast, its geological implications, and how effective tsunami warnings played a crucial role.

Episode notes
Semaglutide Reverses Biological Aging
- Semaglutide drugs like Ozempic slow or even reverse biological aging by lowering biological age by over 3 years on average.
- They reduce inflammation and improve metabolic health, causing organ systems including the brain to appear younger by up to 5 years.
Caution on Using Semaglutide As Anti-Aging
- It is premature to use semaglutide solely for rejuvenation without weight loss since more trials are needed.
- Await results from larger studies assessing effects on diverse groups and long-term safety, especially in older adults.
GLP-1 Drugs and Aging Mechanisms
- GLP-1 receptor agonists may slow aging by reducing visceral fat and inflammation which accelerate aging.
- Biological age clocks offer quicker insight into anti-aging effects than decades-long clinical trials.
