Study: Those Exposed to Asbestos Should Not Take Beta-Carotene
Taking beta-carotene health supplements could increase the risk of lung cancer or death from cardiovascular disease for anyone who is regularly exposed to asbestos, according to a panel of medicine experts. Based on existing scientific evidence, the U.S. Preventive Services Task Force concluded recently that the potential harms of beta-carotene supplements outweigh any benefits, particularly for those with occupational exposure to asbestos. The task force, an independent group of medical volunteers, makes recommendations about clinical preventive services. In the same report, it also said vitamin E provided no benefi...

A genetic mechanism for sexual dichromatism in birds
Sexual dichromatism, a difference in coloration between males and females, may be due to sexual selection for ornamentation and mate choice. Here, we show that carotenoid-based dichromatism in mosaic canaries, a hybrid phenotype that arises in offspring of the sexually dichromatic red siskin and monochromatic canaries, is controlled by the gene that encodes the carotenoid-cleaving enzyme β-carotene oxygenase 2 (BCO2). Dichromatism in mosaic canaries is explained by differential carotenoid degradation in the integument, rather than sex-specific variation in physiological functions such as pigment uptake or transport. T...
