Summary:
 Histones are proteins that are essential in embryo development, as they help to assemble chromosomes, but too little histone will result in DNA damage and too much is toxic. Certain lipid droplets, commonly found in fat, contain high amounts of histones that the body uses to call into action during embryo development. The article tells how scientists have discovered that the lipids that store histones have greater versatility than they first believed. In the past, scientists thought that histones not bound to DNA were toxic, prompting them to be destroyed by the cells. The scientist'  work demonstrates that binding to lipid droplets protects the histones and the DNA, while storing them for later use in chromosome assembly.   This discovery has opened possibilities for medicine development and for greater understanding of the human body.
