Researchers at the University of Washington experimented with genetically modified fruit flies that gradually die of dopamine cells as they reach old age. Laboratory scientist Leo Parank and his team were surprised to find that when they squeezed tobacco and coffee into juice and fed it to the flies, their dopamine cells increased again, and the flies became alive again. However, Leo Parank also points out that fruit flies are sensitive to some chemicals. The effects of chemicals in tobacco and coffee on the human brain need to be tested by further experiments.
