Researchers find molecular switch to make old brains young again

Researchers find molecular switch to make old brains young again | Longevity science | Scoop.it

Researchers at Yale University have found a way to effectively turn back the clock and make an old brain young again.

 

As we enter adulthood, our brains become more stable and rigid when compared to that of an adolescent. This is partially due to the triggering of a single gene that slows the rapid change in synaptic connections between neurons, thereby suppressing the high levels of plasticity of an adolescent brain.

Hydra's immortality gene sheds light on human ageing

Hydra's immortality gene sheds light on human ageing | Longevity science | Scoop.it

The tiny freshwater polyp Hydra is a remarkable creature. It does not show any signs of ageing and appears to be immortal. Researchers from Kiel University have examined this phenomenon and uncovered an important link to the ageing process in humans that could lead to the development of advanced rejuvenation therapies.

 

How does the polyp Hydra do this? It accomplishes the feat of apparent immorality by reproducing through budding rather than mating. Each polyp contains stem cells capable of continuous proliferation. Without this endless supply of regenerating stem cells, the animals could not reproduce.
