Last week I mentioned artificial muscle and skin, both possibly for use in robots.

But I haven't heard much reference to this article in the BBC on artificial blood (or maybe more accurately, instant blood).

Doctors have for the first time successfully used artificial blood to treat patients.
The product is a powder which can be stored for years, say scientists at Stockholm's Karolinska Hospital.

It is made from donated supplies of real blood, which normally has a shelf-life of just 42 days.

The powder can then be mixed into liquid form when needed, and used immediately regardless of the patient's blood type.

This seems like a pretty big deal...anybody else heard anything about it?
