Rat transit markets in everything

Learning to drive small cars helps rats feel less stressed, scientists found.

Researchers at the University of Richmond in the US taught a group of 17 rats how to drive little plastic cars, in exchange for bits of cereal.

Study lead Dr Kelly Lambert said the rats felt more relaxed during the task, a finding that could help with the development of non-pharmaceutical treatments for mental illness.
