I’ve been pondering this notion that certain species can be trained to detect explosives through scent recognition, specifically with regards to the use of rodents like rats in such applications. The idea is not entirely new and has garnered some attention from researchers who have explored various methods for utilizing these animals’ keen sense of smell. Furthermore, it’s worth noting that rats are capable of navigating complex environments relative quickly which could be advantageous when searching through rubble or debris after an explosion. However the technical challenges involved in training such a system to accurately detect explosives before they pose a threat is considerable and would require significant further study.
