Study: Eat leafy green veggies to help prevent cataracts

.... "In addition to protective enzymes and compounds like vitamins C and E, we think that low concentrations of lutein and zeaxanthin in the eye lens help shield the eye from the harmful effects of UVB radiation." What researchers don't know, however, is how these two antioxidants get into the eye....

Read your shampoo's label: Study finds common ingredient stunts developing neurons of rats

...T and related compounds kill harmful bacteria that like to grow near moisture or water. As such, they often are found in personal care products, as well as in water-cooling systems and at factories that require water for manufacturing.
