Red squirrels could beat squirrel pox
Scientists studying red squirrels say things may be looking up for the garden favourites.
For the past 100 years the number of red squirrels has been dropping.
Thousands of red squirrels have been killed by a disease called squirrel pox.
The disease is carried by grey squirrels - but it doesn't affect them.
Now scientists from the University of Liverpool have now found that some red squirrels can recover from the virus.
It's hoped this latest discovery can help reverse the decline of the red squirrel.
