BABIES WITH TWO MOTHERS, IS IT WRONG?
Last March the Institute for Reproductive Medicine and Science of Saint Barnabas in West Orange, New Jersey, reported in the Journal of Human Reproduction in the paper: “Mitochondria in human offspring derived from ooplasmic transplantation: Brief communication,” that they had produced 16 babies that had two biological mothers and that here already 30 worldwide.

MOLECULAR AND CELULLAR MEDICINE ADVANCES = ETERNAL YOUTH? If you have read my previous six articles you know about all the scientific efforts that are being done that could lead to the expansion of the human life span. However, all of those are related to high biotech developments: Gene therapy, xenotransplantation, stem cells, artificial organs, human cloning and gene discoveries. Now, what would you say if life span could be increased 40% just by dieting?
