The short story is this: you can place two species of hydra animals in the same environment at a temperature of 10 degrees Celsius. One will age (Hydra oligactis) and the other one won’t (Hydra vulgaris). Now here are the details. Hydras are primitive multicelullar animals. When well-fed, they reproduce asexually by budding. But when…… Continue reading How temperature switches aging on and off in hydra animals

3 simple things you must do to stop the aging clock
The dose makes the poison. In large doses, a stressor can kill you. In low doses, it can make you stronger. The specific adaptation that a cell derives from being exposed to a low dose of some stressor is called hormesis. And this concept is central to understanding aging. Because if cells – for whatever…… Continue reading 3 simple things you must do to stop the aging clock
Life is chemistry
Life can’t exist without the chemical reactions which are the backbone of metabolism. For a fleeting moment in time called lifespan, such chemical reactions maintain stable internal conditions. We call this homeostasis. Do chemical reactions remain the same with age? According to a new hypothesis of aging – which unfortunately I didn’t get to include…… Continue reading Life is chemistry
The 5 common traits of negligibly senescent species
By studying the processes which give these negligibly senescent creatures longer lifespans, there is the possibility that they could be recreated in humans in order to extend our own. How negligible senescence is achieved by each individual species varies, but here are five of the most common traits. The article I just posted on Life…… Continue reading The 5 common traits of negligibly senescent species
