Warwick researchers discover freezing blood method

Researchers at the University of Warwick say they have discovered a way of preserving blood for longer than the current limit of 42 days.

When blood is donated, it can be kept refrigerated for that time but then passes its use-by date.

It does not respond well to being frozen as the ice crystals thaw in such a way that they tear cells apart, making it unusable.

Now, researchers have discovered a polymer - similar to ones found in wood glue - that disrupts the behaviour of the crystals, and large-scale trials are expected to begin in the next year.
