Research into the pox being spread by the resistant grey squirrel, which is decimating the vulnerable red squirrel population, is underway in Liverpool University. Dead red squirrels with antibodies to the virus have been found in the National Trust woods at Formby, giving hope that a vaccine or controlled breeding programme can save the species. The work is urgent, as grey squirrels are now expanding into Scotland, despite all attempts at creating buffer zones and culling.  Guardian
