Us Versus Them:The Role of National Identity in the Formation of False Memories for Fake News

People are prone to forming false memories for fictitious events described in fake news stories. In this preregistered study, we hypothesized that the formation of false memories may be promoted when the fake news includes stereotypes that reflect positively on one’s own nationality or negatively on another nationality. We exposed German and Irish participants (N = 1,184) to fabricated news stories that were consistent with positive or negative stereotypes about Germany and Ireland. The predicted three-way interaction was not observed. Exploratory follow-up analyses revealed the expected pattern of results for German participants but not for Irish participants, who were more likely to remember positive stories and stories about Ireland. Individual differences in patriotism did not significantly affect false memory rates; however, higher levels of cognitive ability and analytical reasoning decreased false memories and increased participants’ ability to distinguish between true and false news stories. These results demonstrate that stereotypical information pertaining to national identity can influence the formation of false memories for fake news, but variations in cultural context may affect how misinformation is received and processed. We conclude by urging researchers to consider the sociopolitical and media landscape when predicting the consequences of fake news exposure.</p

Anti-phosphorylated histone H2AThr120: A universal microscopic marker for centromeric chromatin of mono- and holocentric plant species

Based on the analysis of 20 different monocot and eudicot species, we propose that the centromeric distribution of the phosphorylated histone H2AThr120 is evolutionary highly conserved across species with mono- and holocentric chromosomes. Therefore, antibodies recognizing the phosphorylated threonine 120 of the histone H2A can serve as a universal marker for the cytological detection of centromeres of mono- and holokinetic plant species. In addition, super resolution microscopy of signals specific to the centromere-specific histone H3 variant CENH3 and to H2AThr120ph revealed that these histone variants are incorporated into different nucleosomes, which form distinct, partly intermingled chromatin domains. This specific arrangement of both histone variants suggests different centromeric functions during the cell cycle
