Harvard team develops oPhone, trades scents between New
York, Paris
Who hasn’t been transported back to childhood by the sweet
aroma of baking cookies, or to a favorite forest by the earthy smell of leaf
litter, or to a summer beach by the tang of salt air?
Harvard Professor David Edwards and a former student, Rachel
Field, want to harness the evocative power of smell, not just to bring us back,
but to bring us closer.
