[extropy-chat] Cancer-resistant mice age normally

[Joao Magalhaes]

Hi,

It looks like cancer-resistant mice have a normal lifespan and age normally.

Here's a link to the story on BBC:

This is a very nice work by Manuel Serrano's group in Madrid as it shows 
that increasing cellular defences against damage, while influencing cancer, 
does not impact on aging. What it tells me is that aging is not merely a 
result from damage accumulation. It also raises questions on the link 
between cancer and aging--one which I've argued for in the past.

All the best,

Joao
