NAIVE CD4 T CELLS, which normally make up about half of the CD4 T cells circulating in the body, mount the body's initial response to infections such as HIV. According to research reported in the April Journal of Clinical Investigation by Mario Roederer, a genetics research associate, and colleagues, HIV can't replicate in these cells and hence can't directly harm them, so the finding could lead to a new weapon against HIV.

ACTIVATED AIR BAGS can inflict severe eye injuries even in minor car accidents, according to a small-scale study authored by Edward E. Manche, assistant professor of ophthalmology, and colleagues in the March Journal of Ophthalmic Surgery and Lasers. The paper reviews five air bag injury cases treated at the UCLA ophthalmology trauma service between 1993 and 1995.
