Rejuvenation breakthrough: Scientists reverse 60 years of aging in human cells

Scientists converted blood cells from an 80-year-old into neural stem cells with a molecular age of under 20, effectively reversing more than 60 years of cellular aging in the laboratory. The researchers say the discovery offers a new way to study how cells become younger and could help researchers better understand age-related diseases such as Alzheimer's; the work remains at the laboratory stage.
