The Belly Button Biodiversity Project found around 1,400 types of bacteria, more than 600 of which were unknown to science— they were completely new, unclassified organisms!

We are born without any bacteria on our skin, but as soon as we are exposed to the world we start to accumulate microbes. The places we go, the things we eat, the people we interact with — they all affect our "microbial signature." Our belly buttons — or really, the bacteria they contain — are reflections of our lives.

What’s going on here?[peptidoglycan (PDG) vs chitin]

PDG (peptidoglycan)

β-Lactam antibiotics inhibit the formation of peptidoglycan cross-links in the bacterial cell wall

How will β-Lactam antibiotics like penicillin affect… you?plants?fungi?virus?
