That’s what one group of students did for a study published in Science Advances. Researchers made 3D printed, candy-sized models of proteins, and asked some of the students to identify them with their mouths.
The researchers blindfolded 281 college students, gave them the models, and asked them to identify what the models were supposed to be. Some used their mouths to try and figure it out, while others used their hands.
