Do the math, say UCLA researchers

In 2008, Reuben Granich and his colleagues at the World Health Organization published a paper in the medical journal The Lancet that proposed a new strategy for combating HIV in South Africa, a country staggered by the virus, with as much as 18 perc…

Quantum Dots Used to 'Draw' Circuits for Molecular Computers

By using tiny quantum dots to create trails of altered molecules, UCLA researchers are developing a method of producing nanoscale circuitry for the molecular computers of the future that will use molecular switches in place of transistors.
“This technology, although still in the unpublished, proof-of-concept stage, could eventually lead to a relatively inexpensive means of patterning interconnections between the logic gates of a molecular computer,” according to Harold G. Monbouquette, professor of chemical engineering at UCLA’s Henry Samueli School of Engineering and Applied Science, who leads the team.

Common Acne Treatment Stops Blindness in Animal Model

Administering Accutane, a drug commonly used to treat acne, UCLA researchers have successfully stopped the accumulation of toxic pigments in the eyes of animals with a genetic defect similar to Stargardt’s macular degeneration. The UCLA team gave a daily injection of Accutane to mimic the effect of constant light deprivation and the results proved dramatic. These toxic pigments, called lipofuscin, are responsible for the visual loss in patients with Stargardt’s disease.
