Possible good news for the red squirrel.
The BBC reports that scientists have found that some red squirrels have developed an immunity to squirrel pox a disease that has ravaged their numbers.
The pox is transmitted by grey squirrels; but while greys suffer no ill effects from it, if a red catches the virus it is dead within weeks.
The findings, published in EcoHealth, suggest a vaccine could now be developed to help to save red squirrels in Britain from extinction.
