The next time your stomach turns at the smell of spoiled food or the sight of feces, pay attention. New research, published in the Proceedings of the National Academy of Sciences on Feb. 15, suggests that disgust could be the body’s way of helping people avoid infection giving new meaning to the phrase “trust your gut.”
The study is the first in its field to directly test whether people who experience a greater pathogen disgust sensitivity that is, people who are more sensitive to feeling disgust will become exposed to fewer pathogens in their local environments, and thus suffer fewer infections, according to Theresa E. Gildner, assistant professor of biological anthropology in Arts & Sciences at Washington University in St. Louis and study co-author.
Research from Washington University in St. Louis helps flesh out the origin story for the so-called “lost crops” of the Midwest and Northeast. These plants that may have fed as many Indigenous people as maize, but until the 1930s had been lost to history. Natalie Mueller, assistant professor of archaeology in Arts & Sciences at Washington University in St. Louis, shares evidence that bison were “co-creators” along with Indigenous peoples of landscapes of disturbance that gave rise to greater diversity and more agricultural opportunities.

The past year has been a terrible one for the standardized testing industry, as colleges have shifted to test-optional policies and test cancellations have plagued administrations.

It was around before the pandemic but has taken off during the year of COVID-19.
