Wow: The quest the two researchers embarked on to build this nose began in 2019. That was when they heard reports of Joy Milne, a retired nurse living in Scotland, who could detect people with Parkinson’s from a distinctive odour they emitted—distinctive to her, at least, though for reasons still obscure, undetectable by others. Mrs Milne first noticed this odour when her husband developed the illness. She made the general connection later, when she smelled it at sufferers’ support groups attended by her spouse. Tests using clothes worn by patients confirmed her ability. She even noted one seemingly healthy individual as having the disease months before other symptoms developed.
