From Dewi Morgan
The idea of rescue rats trained to locate trapped survivors is appealing (25 September, p 21). However, I note that the design has feedback only to the pleasure area of the rats’ brains, not to the “don’t eat that, it tastes vile” area, if there is such a thing.
Which leads one to ask what the first instinct of a rat will be on finding a wounded, immobilised person?
