Genetic links could unlock clues to leading cause of blindness

...ral visible light. Frequent exposure to blue light rays has been linked to macular degeneration. If the disease is going to be treated early, Dawson said researchers must know the significance of these factors. Aside from studying early environmental risks, the next step for researchers is to map the spe...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...s are particularly vulnerable to cancer-causing UV rays from the sun. But the rest of the animal kingdom ?insects, fish, birds, amphibians, marsupials, and even bacteria, viruses and yeast ?retained a greater ability to repair such damage. Since the 1940s, scientists have been trying to understand how th...

Metal-containing compounds show promise as HIV weapon

...patterns made when the component atoms deflect the rays are deciphered. The metallacarboranes appeared to occupy the portion of the protease used to hold key proteins in place as part of the infective cycle of HIV, preventing the proteases from working. Other advantages are that the compounds are stabl...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

...ight waves, which are slightly longer than visible rays of light and pass harmlessly through our cells," Dai says. But shine a beam of near-infrared light on a carbon nanotube, and the results are dramatic. Electrons in the nanotube become excited and begin releasing excess energy in the form of heat. In...
