By combining mark-recapture and genetic parentage data from wild #lizards, we show that the offspring of older parents do not have lower survival or reproductive success than the offspring of younger parents:

Parental age effects on offspring fitness in a wild population of a short-lived reptile
Abstract. As organisms age, the fitness of the offspring they produce can decline, which is often attributed to parental senescence. However, few studies h

I ❤️ inventions like that: bladeless wind power. ‘Instead of blades, these turbines use a tall, mast-like structure that oscillates or vibrates due to the aerodynamic phenomenon of vortex shedding. This oscillation is then converted into electricity.’

Why does eating less extend lifespan? 🧬
Mutation accumulation underpins evolution of lifespan extension by dietary restriction
We often think about saving energy or recycling waste - but we show how evolution acting on mutation load can generate longer life on low food 🧵
