The researchers used harmonic radar, a technology developed in 1996 by the Greenwich group to allow individual insects to be tracked in flight.

A new study shows that genetic variations that confer longevity in some fruit flies often turn out to have adverse effects on flies of the opposite sex or those in a different environment.
