Abstract
The cellular world has some daunting problems for biologists. For example, cells use the ubiquitin molecule in different ways to achieve different effects. These tangled events come under the spotlight in new work.
The cells in our bodies need to interact with each other and with the environment around them. For example, they take up certain nutrients (such as cholesterol, vitamin B12 and iron) from their environment, and can signal to each other with messenger molecules that activate receptor proteins on the cell surface.
