Categorizing Cancers: Gene activity predicts leukemia outcome
By dividing acute myeloid leukemia into subtypes on the basis of which genes are abnormally active in a given patient, doctors may be able to predict outcomes and make better treatment decisions.

Could refrigeration explain Crohn’s rise?
Crohn's disease, marked by inflammation of the small intestine, could be caused by refrigeration of meats, a process that selects for hardy bacteria that handle cold temperatures well, researchers hypothesize.

All Roads Lead to RUNX
Genetic mutations that predispose some people to the autoimmune diseases lupus, psoriasis, and rheumatoid arthritis appear to have a common molecular feature: They derail the work of a protein, called RUNX1, that regulates how active certain genes are.
