When self-image takes a blow, many turn to television as a distraction

Whether you fancy yourself a jet-setting sophisticate or a down-to-earth outdoorsy type, a fast-track corporate star or an all-around nice guy, new research indicates that you probably tune out information that challenges your self-image by tuning in to television. “We each have ways in which we like to perceive ourselves,” said one of the lead researchers. “In many cases self-image is carefully constructed and zealously guarded, and it’s difficult to experience a conflict between who we are and who we would like to be. Television appears to be an effective means of reducing awareness of how we are falling short of our own standards.”

Studies dispute ultraviolet effect on declining amphibian populations

For several years it has been widely believed that increased ultraviolet-B radiation because of thinning of atmospheric ozone was a major culprit in deforming amphibian offspring and dwindling populations. Now two new studies cast serious doubt on that assumption, and the lead author of one says the belief could have had negative impacts on efforts to save amphibians. “All of the concentration on UV might have misdirected our conservation and research priorities,” said Wendy Palen, a University of Washington zoology doctoral student.
