Preliminary results from ACTG 315 show that an antiretroviral drug cocktail can partially restore immune function in people with moderately advanced HIV disease. The study found increases in CD4+ T cell counts, decreased plasma levels of HIV, and improved immune response.
MIT researchers verify coherence property in atomic beam, a key attribute of optical lasers, and extract controlled fraction of atoms from Bose-Einstein condensate to produce directional stream. This breakthrough may lead to significant innovations in nanotechnology and precision measurements at the quantum level.
A team of researchers has solved a centuries-old puzzle in eye development by discovering that the embryo has a single eye field that normally separates into two. The study found that an inhibitory signal shuts off gene expression in the middle of the eye field, leading to cyclopia if this fails to happen.
