An Introduction to the Microbial Cosmos
Too often, microbes are thought of as nothing more than germs, agents of disease. Meanwhile, these tiny alchemists are busy breaking down pollutants, synthesizing psychedelic substances, or crafting some of our favorite fermented beverages! The Museum of Beadwork and the Microbe Institute want to change the way we think about the invisible lifeforms who share this planet with us (and who vastly outnumber us).
As part of a truly remarkable–and GLITTERY–participatory science, art, and education experience to open in 2026 at the Museum of Beadwork in Portland, Maine, we’re asking you to help us reveal this unseen world through the use of beadwork. To learn more about the call for new art, as well as the opening date of the new exhibit, please visit the link below. To help inspire you to create such art, we’ve provided a brief intro, and collection of resources on this page to welcome you to the microbial cosmos.

Microbes: The Basics
Microorganisms, or 'microbes,' include bacteria, fungi, protists and viruses. They are a group of creatures that are so small that we often need a microscope to see them. The smallest and most basic unit of all living things is a cell. Microbes can be just one cell or have many cells (multicellular).* Even with one cell, microbes can eat, drink, excrete waste, grow and reproduce.
Microbes come in various shapes and sizes—some are spheres, while others are hot dog-shaped. Some look like long strings. Some microbial species can even move around and change their shape. Most microbes divide asexually, which means one cell divides into two to make new and more microbes. Depending on the microbe species and where they live, they can reproduce in 20 minutes, or take decades to replicate.
Mushrooms are a fungus. They are the fruiting bodies—reproductive structures—produced by certain fungal species. While some fungi produce mushrooms, others live their lives as nearly invisible cells.
* Viruses, unlike other microbes, are not made from cells and require host cells to reproduce.
Microbes can live almost anywhere. They are present in clouds, in dust particles floating in air, in water, in the deep floors of the ocean, in soil, food, and plants. They’re even in our dishwashers and washing machines. They live on you and in you. They are everywhere!
They are also extremely diverse. For example, there are more microbial species in our backyard soil than there are species of animals or plants in this world. Only a very tiny minority of all microbial species cause disease or are harmful to humans. Most microbial species are either harmless or helpful to us. Today, scientists use microbes to help crops grow, to clean up pollution, and to produce many of our life-saving medications.
