After discovering that children who grow up on farms are less likely to suffer from asthma and allergies, researchers are trying to isolate the compounds in farm dust that lead to this protection. This ongoing research highlights a fascinating aspect of how our environment influences health. By examining farm dust, scientists hope to uncover natural compounds that could serve as protective factors against respiratory issues, opening avenues for new treatments or preventive measures to mitigate allergies and asthma in urban populations. When tackling language nuances such as verb tense, remember to choose the tense that best reflects the timing of actions. In this case, "are trying" suggests that the research is current and active, while past tenses might imply the work has been completed or set aside.
