By harnessing a unique property of yeast, scientists can synthesize histones and the enzymes that modify these proteins, which spool DNA and influence gene expression.
Obese mice that exercised while pregnant gave birth to pups that grew up free of the metabolic issues present in the adult young of sedentary obese mothers—possibly by staving off epigenetic changes to a key metabolic gene.
Weill Cornell Medicine geneticist Christopher Mason speaks with The Scientist about a bolus of new work on the physiological, cellular, and molecular effects of leaving Earth.
Certain populations have been historically underrepresented in genome sequencing studies, but the NIH, private clinics, and 23andMe and other companies are trying to fix that.
Using CRISPR and other tools, scientists are modifying DNA methylation, histone marks, and other modifiers of gene expression to understand how they affect health and disease.
