(Phys.org)—A team of researchers at Purdue University in the U.S. and the University of Amsterdam and Université catholique de Louvain in the Netherlands has isolated the gene responsible for producing a protein that aids ...
The same mechanisms that quickly separate mixtures of oil and water are at play when controlling the organization in an unusual part of our DNA called heterochromatin, according to a new study by researchers at the Department ...
