Researchers in the US say they might have discovered how to combat and even reverse some processes of ageing, at least in mice.
Scientists at Stanford University suggests blood taken from young mice and injected into older mice boosts the brain functions of the older mice.
In the study, 18-month-old mice were injected with the blood plasma of three-month-old mice. “The injected mice performed better on memory tests than mice of the same age that had not been given blood plasma,” said one scientist.
"There are factors present in blood from young mice that can recharge an old mouse’s brain so that it functions more like a younger one," said another.
So basically Elizabeth Bathory was right though.
