Unlike most places in the brain,

, the olfactory system is constantly replenished with a steady stream of newborn neurons. To tell the brain what the nose has smelled,

, these newbies must send message-sending tendrils called axons to very specific blobs of neural tissue called glomeruli. Each neuron carries one type of odor-detecting protein,

, which determines the axon’s final destination.
Those destinations can be disrupted when certain neurons are engineered to contain a different odor-sensing protein, Barnea and Lulu Tsai of Drexel University in Philadelphia found in one of the studies,

. This engineered odor-sensing molecule was a bad influence: It incited other neurons’ axons to go to the wrong glomeruli,

. Researchers don’t know whether this mistake affected the animals’ sense of smell.
The axons were vulnerable to diversion only for a brief window of time, Barnea and Tsai found. When the engineered odor-sensing molecule was produced right after birth,
