"[D]ogs steal food quietly to make sure they don't get caught.... [P]revious studies had found that dogs are more likely to take food when people are not watching them."
And at p. 17, same issue... not to be outdone -- another work of genius involves the study of one  baby, whose diet was carefully monitored while stool samples were monitored for bacteria... presumably under the supervision of a Cornell University prof on maternity leave:
"Baby's gut bugs are shaped by diet. ... While the baby was breastfeeding, the bacteria in his stomach contained numerous genes useful for breaking down milk sugars. When he moved to a diet of solid foods, there were more bacteria with genes that influence starch digestion."
