Zinc-deficient children living in communities where they do not receive adequate amounts of zinc from their diet should be given supplements, even if they are HIV-infected, according to researchers from the Johns Hopkins Bloomberg School of Public Health.

Silenced gene in worm shows role in regeneration
Researchers at the University of Utah have discovered that when a gene called smedwi-2 is silenced in the adult stem cells of planarians, the quarter-inch long worm is unable to carry out a biological process that has mystified scientists for centuries: regeneration.
