Between one-third and one-half of individuals in the United States who were infected with HIV around the time of birth may not have sufficient immunity to ward off measles, mumps, and rubella—even though they may have been vaccinated against these diseases. This estimate, from a National Institutes of Health research network, in collaboration with the Centers for Disease Control and Prevention, is based on a study of more than 600 children and youth exposed to HIV in the womb.

Researchers, using novel large-scale imaging technology, have mapped the spatial location of individual genes in the nucleus of human cells and identified 50 cellular factors required for the proper three-dimensional (3D) positioning of genes. These spatial locations play important roles in gene expression, DNA repair, genome stability, and other cellular activities.
