Summary: The 'Original antigenic sin' hypothesis suggests that when individuals are infected with a mutated variant of a pathogen, their immune response will be dominated by antibodies that target the original pathogen. Schiepers et al. provide support for this hypothesis using transgenic mice that have tagged antibodies based on their cellular origins and kinetics. They observe that cross-reactive antibodies accumulate mainly in long-lived immune responses.

Summary: Most eukaryotic genes are processed by the major spliceosome U2, but U12-type introns are rare. A recent study uncovered extensive U12-type intron gain and revealed an unexpectedly flexible and efficient minor spliceosome U12.

Summary: By studying the color phi phenomenon, a small neural network model is proposed that emphasizes the importance of dynamic behavior, showing how anomalous temporally-reversed perception of stimuli can appear based exclusively on bottom-up dynamics. Additionally, the results suggest that the color phi phenomenon might simply be a feature of the inherent dynamical and nonlinear sensory processing in the brain, and in and of itself is not related to consciousness.

Summary: Cerebral achromatopsia is a rare acquired color perception impairment caused by brain injury, with most cases involving bilateral or right hemisphere lesions. It differs from congenital color blindness by affecting perception of all colors. A study on stroke patients with posterior cerebral artery involvement found that 22% of patients showed significant color discrimination problems, with bilateral lesions associated with more severe impairments.

Summary: Immune thrombocytopenia (ITP) is an autoimmune bleeding disorder characterized by low platelet count. Platelet--autoantibodies and/or cytotoxic T cells, as well as the spleen, play important roles in its pathophysiology. The presence of accessory spleen (AcS) may contribute to ITP relapse after splenectomy. Pizzi et al. conducted a study comparing the immunological composition of AcS and main spleens in ITP patients, and found similarities between the two, suggesting the potential involvement of AcS in ITP relapse post splenectomy.

Summary: This study examines the phenomenon of non-human influencers on social media and analyzes user engagement factors through the analysis of user comments on Instagram posts. The findings suggest that users engage with non-human influencers for various reasons, and the study proposes a framework for the conceptualization of non-human influencers and presents research questions for future exploration. The implications of this study are significant for brands and businesses seeking to work with non-human influencers in their marketing strategies.

Summary: A recent analysis of the white dwarf sample in the SDSS survey has identified a well-defined ultracool or IR-faint white dwarf sequence in the Hertzsprung-Russell diagram. This discovery has allowed for the expansion of the IR-faint white dwarf sample, leading to the identification of new candidates through optical spectroscopy and model atmosphere analysis.

Summary: Most studies in the field of molecular electronics have focused on modifying the backbone of the molecular wire to adjust the electrical properties of the entire junction. However, the impact of the chemical structure of the anchor groups on the electronic structure and conductance of the system is often overlooked. In this study, we synthesized electron-accepting dithienophosphole oxide derivatives and constructed single-molecule junctions. Our findings revealed that the anchor group significantly affects charge-transport efficiency, with electron-deficient 4-pyridyl contacts suppressing conductance and electron-rich 4-thioanisole termini promoting efficient transport. Our calculations attribute this phenomenon to subtle changes in charge distribution at the electrode interface.

Summary: This study aimed to assess the predictive function of personal and social factors on the four roles in cyberbullying phenomenon. The results showed that aggressive humor predicted cyberbullying perpetration and negatively predicted cyber-defending. Self-defeating humor predicted all four roles, while affiliative humor predicted cyber-defending and self-enhancing humor predicted cyber-victimization. Peer norms predicted all four roles, while parental education about Internet use did not prove to be a significant predictor.

Summary: Research has shown that individuals can regulate emotional biases in risky judgment and decision-making processes through cognitive reappraisal. Distancing moderates the relationship between fear and risk taking, as well as anger and risk taking. Increasing levels of distancing can help individuals reduce the impact of fear on risk taking and risk estimation.

Summary: Vascular epiphytes can grow in tree crowns at suitable microhabitats, showing better growth conditions with higher nutrient concentrations, higher specific leaf area, and lower leaf dry matter content. The availability of old and structurally diverse trees is crucial for vascular epiphytism in the study area, suggesting the importance of preserving such trees in secondary forest ecosystems.

Summary: WD 0810-353 is a white dwarf predicted to pass within 1 pc of the solar system. However, it has a magnetic field with a strength of about 30 MG, unlike normal stars. New polarized spectra suggest that the star has regions of different field strength and opposite polarity. The radial velocity estimate from Gaia spectroscopy is rejected, indicating that there will probably be no close encounter between the solar system and WD 0810-353. It is a stellar remnant with a strong and complex magnetic field in the solar neighborhood.

Summary: Recent literature suggests that radical right parties tend to have moderate economic stances, but this paper argues that they take a clear stance favoring consumption policies in terms of the goals and principles the welfare state should meet. Empirical analysis based on new coding of welfare stances in party manifestos and original data on voters' perceptions supports this argument, highlighting the RRPs' emphasis on defending the traditional welfare state's consumptive focus.
