Altering genes could let us live to be 500

The greedy human beings have been desiring to live up to ten thousand years. Scientists are also working hard on this aspect. Recently, researchers from the United States claimed that it might be possible to increase the human lifespan five times by changing genes.

So far, this research result has only been proven effective on worms. Researchers in the laboratory extended the life of Caenorhabditis elegans (a type of nematode) by altering two groups of gene channels, increasing its lifespan five times.

The researchers thus proposed the hypothesis of gene anti-aging. Dr. Pankaj Kapahi from the Buck Institute of Age Research said, "We have increased the lifespan by five times. The positive feedback brought by the two mutations has extended the life of some special tissues. If such technology can be applied to humans, it would allow humans to live to 400-500 years old."
