Imagine being 80 years old and discovering that some of your body’s cells could be made to resemble those of a teenager. It sounds like something pulled straight out of science fiction, but researchers in Germany have achieved something remarkably close in a laboratory experiment. Scientists at the University of Bonn have reprogrammed blood cell …
Scientists have found a way to make cells from an 80-year-old donor display a molecular age of less than 20, opening up new possibilities for studying how the body ages. The discovery came with an unexpected detail: the rejuvenation happened gradually, allowing researchers to watch the process unfold over more than 100 days. The research, …
What if an organ’s age were not as fixed as scientists once thought? A new Harvard-led study suggests that transplanted hearts can begin to take on the biological age of the people they enter, with older hearts showing molecular signs associated with rejuvenation inside younger recipients. The research is still preliminary, but it raises a …
A cancer gap has emerged among Americans under 50, and women are carrying much more of it. In 2021, women in this age group were diagnosed at nearly twice the rate of men. The reasons remain unsettled. Researchers are now examining everything from diet and biological aging to environmental exposures that may begin influencing the …
A team of Cambridge scientists may have taken one of the biggest steps yet toward slowing the effects of human aging. Researchers at the Babraham Institute managed to rewind the biological age of human skin cells by around 30 years while keeping the cells fully functional. The breakthrough sounds like science fiction, but the researchers …
