Regeneration.

[swestrup]

Scientists in Australia have announced that they have produced mice that can regenerate all of the various tissues of their bodies, except for the brain. This trick also seems to be transferable by injecting non-regenerative mice with fetal cells from the regenerating strain.

This certainly has possibilities! The next thing I want to know is how susceptible to cancer these creatures are, since one theory of why mammals don't regenerate has to do with increasing our resistance to cancer.

I envision a multi-tiered immune system;
* Cancer-killing oncovirus, waiting in the blood for tumours to infect;
* Infection-fighting crocotilian macrophages;
* Regenerative stem cells repairing damage and replacing worn-out cells.

The body of the future, without any need for nanotech!
