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

Regeneration from simple to complex animals and back
Less turnover. Less replacement. Aging is mainly tissue attrition. Hence regeneration research is where time, money and energy are best spent when it comes to solving the puzzle of aging. Because the ability to regenerate is often – but not always – found in species with negligible senescence. Coupled or not with slow growth. There…… Continue reading Regeneration from simple to complex animals and back
Aging is the loss of cell polarity maintenance
There are 2 ways to deal with the inevitable damage that takes place in an organism in time: 1. You can try to repair it. 2. You can try to limit it. The first solution is usable, but expensive. Energetically expensive. Species mainly use it on the short-term. Some kind of repair is needed for…… Continue reading Aging is the loss of cell polarity maintenance
How to buy time for free: calorie restriction with optimal nutrition without daily tracking software or measuring ingredients
No matter who you are, the day still has 24 hours in it. Aside from slowing down the rotation of Earth around the sun, how can you actually buy time? You can do that by trying a method that extended the average and maximum lifespan of several species: calorie restriction with optimal nutrition. And while…… Continue reading How to buy time for free: calorie restriction with optimal nutrition without daily tracking software or measuring ingredients
