...Jing Wen; Fangzhong Yang; Meihua Che Antibiotic resistance has become one of the major public health threats of the 21st century. Bacteria serve as an excellent model organism, allowing scientists to study evolution in a short amount of time. There are many misconceptions among students regarding...

It is advantageous for students to know about natural selection and coevolution before using the case study. Case studies are stories...

A diet of sugar- and fat-rich foods will cultivate less diverse bacteria and species that cause inflammation in your gut and impair memory and focus ( Quercia et al...

The ability to culture skin bacteria on agar plates and extract potential environmental factors from their own everyday lives make the human skin microbiome a model example for students to develop their own hypotheses about the variability both within and between different...

This exercise is done in three consecutive lab sessions. During Lab 1, students prepare a standard nutritive medium that has been mixed...

...Jesse A. Lewis; Nadja Anderson In this lesson students will use the Penicillium chrysogenum fungus, which naturally produces the antibiotic penicillin, to investigate the effect of naturally produced antibiotics on bacteria in laboratory cultures. Students co-culture P. chrysogenum with three...
