Crocodiles, salamanders and turtles they can have the secret of humans can live up to 150 years, as the experts expected. For decades, scientists have struggled in their quest to find anti aging herb. Experiment with cold-blooded animals like turtle, which are known to outlive other animals of their size, can change our luck.
Researcher from Michigan State University they hope to discover “traits” that can also be used in humans. However, team have not identified potential longevity targets and any significant discovery could be years away.
Principal researcher and biologist, Professor Anne Bronikowski, said: “Understanding the comparative landscape of aging in animals it may reveal flexible properties that might be viable targets for biomedical studies related to human aging.”
For his part, co-author, Professor David Miller, from pennsylvania state university, added: “If we can understand what makes some animals age more slowly, we can better understand aging in humans.” In addition, he explains that in theory it can help inform conservation strategies for threatened or endangered species.
In profession, published in magazine Science, experts observe 77 different species of reptiles and amphibians in habitats scattered throughout the world. Some show signs of “insignificant aging.” Although all living organisms age and die, not all beings follow the same pattern from weakness and decline to old age and death.
“Negligible aging means that If the probability of an animal dying in one year is 1 percent at 10 years, if you live at 100, the chance of dying is still 1 percent.” Miller. “In contrast,” he continued, “in adult women in the United States, the risk of dying in one year is about 1 in 2,500 at 10 years and 1 in 24 at 80 years. When a species exhibits negligible aging (decline), senescence does not occur. .”
Researchers attribute this, in large part, to Turtles have hard shells to protect them from being eaten. Crocodiles are protected by their thick scales, while salamanders can fall back onto their poisonous skin. None of this clearly applies to humans. However, scientists believe that Another answer to how they can resist aging may be hiding deep within their bodies.
Findings too they helped improve previous scientific consensus linking the long life spans of some reptiles to their slower metabolisms. Because cold-blooded creatures draw energy from the environment, unlike mammals such as humans, which need to burn calories to stay warm, They don’t need to eat much which gives them a slower metabolism.
Previously this is thought to be the key to some reptiles that can live up to 190 years. However, a new analysis found that no relationship between slower metabolism and longer life by comparing its 77 species with warm-blooded creatures of the same size.
The oldest land animal in the world today is the giant tortoise in Seychellois called Jonathan, who is 190 years old. Data from National Statistics Office shows that life expectancy at birth in the UK is 79 years for men and just under 83 years for women. But a 150-year life expectancy, once thought to be a distant dream, is now getting closer to reality, according to some scientists.
In March this year Leading aging experts say children born in 2070 can live up to 150 years thanks to advances in reverse aging technology. This statement follows a groundbreaking study earlier that month that successfully reversed the aging process in aged mice.
