Many scientists believe that the further a cell is from the embryonic stem cell stage, the harder it is to make a successful clone using that cell’s genetic material. Now, researchers at Whitehead Institute for Biomedical Research have cloned mice using olfactory neurons – cells far removed from the embryonic state.

New research into a family of cell wall proteins shows how yeast can present a variety of “faces” to its environment. In pathogens like yeast, these cell surface proteins regulate how the cell sticks to other cells, interacts with surrounding tissue and evades detection by the immune system.

The story of life and all its associated processes takes place within a vast universe of proteins and their interactions, a bountiful frontier ripe for exploration.
