We conducted an experiment to test whether altering the saliency of information provided by experts in fictitious news stories on climate change triggered different emotions among readers. Based on appraisal theories of emotions in the psychology literature, we hypothesized that 1) news stories that presented climate change related threats as diffuse and uncertain would elicit greater levels of anxiety, while 2) stories that provided a specific target to blame would induce greater anger, and 3) those that underlined the potential of (...) technology and human efforts to solve climate change related issues would elicit greater levels of hope. We found that while all news stories concerning climate change elicited high levels of anxiety, there were statistically significant differences between the emotions expressed by participations in the expected directions. We discuss the potential implications of these findings for climate change communication and for public opinion on climate change. (shrink)

Telomeres are protective caps for chromosome ends that are essential for genome stability. Broken chromosomes missing a telomere will not be maintained unless the chromosome is ‘healed’ with the formation of a new telomere. Chromosome healing can be a programmed event following developmentally regulated chromosome fragmentation, or it may occur spontaneously when a chromosome is accidentally broken. In this article we discuss the consequences of telomere loss and the possible mechanisms that the enzyme telomerase employs to form telomeres de novo (...) on broken chromosome ends. (shrink)
