The slower you grow, the longer you live: Growth rate influences lifespan

The slower you grow, the longer you live: Growth rate influences lifespan | Science Communication from mdashf | Scoop.it

New research from the University of Glasgow suggests that lifespan is affected by the rate at which bodies grow early in life.

 

A team from the University’s Institute of Biodiversity, Animal Health and Comparative Medicine altered the growth rate of 240 fish by exposing them to brief cold or warm spells, which put them behind or ahead their normal growth schedule.  Once the environmental temperature was returned to normal, the fish got back on track by accelerating or slowing their growth accordingly. However, the change in growth rate also affected their rate of aging. 

 

While the normal lifespan of sticklebacks is around two years, the slow-growth fish lived for more than 30 percent longer, with an average lifespan of nearly 1000 days. In contrast, the accelerated-growth fish had a lifespan that was 15% shorter than normal.

mdashf's insight:

they should check if this is statistically in confirmation with Einstein's Relativity which says "more enegy automatically means ime runs faster and less energy means time runs slower" hence having less energy spent per unit time allows this energy to be spent over a longer period time and hence aging slower. Slowe metabolic activites should entail longer ife span and even Einstein had said so "bilogical aging and the rate at which physical processes are governed by Relativity" b/cos they are to be governed by physical laws and Einstein's law is a physical law as well.

Permanently dye white hair with gold nanoparticles

Permanently dye white hair with gold nanoparticles | Science Communication from mdashf | Scoop.it

Attention seniors: French scientists have developed a process that permanently dyes white hair without harmful chemicals.

 

Philippe Walter and colleagues soaked white hairs in a solution containing fluorescent gold nanoparticles.

 

The hairs turned pale yellow and then darkened to a deep brown. The color remained even after repeated washings.

where do you think the golden aura in my hair comes from ?

When is this going to be commercially avaiable?
