Eternal youth is the concept of human physical immortality free of aging. And it seems that scientists have crossed a key milestone on the way to humanity's dream.
American researchers successfully transformated old human cells into young and healthy ones! They say that technique could extend human life and provide new hope for battling diseases that arise from old age.
The technique, using a modified form of RNA, increases the length of the "telomeres', which are the protective caps on the end of chromosomes that impact ageing and disease. In young people, telomeres are about 8,000-10,000 organic molecules, or nucleotides, long.
"Now we have found a way to lengthen human telomeres by as much as 1,000 nucleotides, turning back the internal clock in these cells by the equivalent of many years of human life. There are also implications for treating conditions of aging, such as diabetes and heart disease," said Helen Blau of Stanford University.
The researchers also hope that the method will be able to allow scientists to generate large numbers of cells that could someday lead to an effective anti-aging drug.
