Genetically Reprogramming Biological Clocks: One Step Closer To The Fountain Of Youth

Aging, the cruel fate from which no one can escape, is associated with drastic physiological changes amplified by the increased expression of genes related to cell damage. This uncontrolled expression contributes to the natural aging of our organs and tissues which gradually lose the ability... click to read more

Genetics agrees: Africa is thriving in diversity

Since the Human Genome Project published the first sequence of the human DNA code in 2001, the field of human genetics has dramatically expanded. New studies have identified specific changes in the DNA code (or genetic variants) that are linked to why some people are... click to read more
