A substantial literature demonstrates public polarization over climate change, particularly among the science literate. The dominant explanation for this phenomenon is that science literacy amplifies directional motivated reasoning, the tendency to interpret evidence such that it confirms desired conclusions. However, the evidence regarding this biasing account of science literacy is inconclusive. The present study tests the biasing account of science literacy in a national survey experiment among the U.S. population. Although results replicated the typical correlational pattern of political polarization as a function of science literacy, results delivered little support for the core causal claim of the biasing account—that science literacy drives motivated reasoning, and  polarized belief-updating. First, results delivered little evidence that science literacy amplified motivated reasoning, despite strong motivated reasoning effects. And second, results delivered little evidence that science literacy amplified polarized belief-updating. That is, the science literate were polarized, but science literacy was not polarizing. These results help clarify the role of science literacy for public beliefs about contested science.

The Individual

Conspiracy theories are playing an increasingly prominent role worldwide in both political rhetoric and popular belief. Previous research has emphasized the individual-level factors behind conspiracy belief but paid less attention to the role of elite framing, while focusing mostly on domestic political contexts. This study assesses the relative weight of official conspiracy claims and motivated biases in producing conspiracy beliefs, in two countries where identities other than partisanship are salient: Georgia and Kazakhstan. I report the results of a survey experiment that depicts a possible conspiracy and varies the content of official claims and relevant contextual details. The results show that motivated reasoning stemming from state-level geopolitical identities is strongly associated with higher conspiracy belief, whereas official claims have little effect on people’s perceptions of conspiracy. Respondents who exhibit higher conspiracy ideation are more likely to perceive a conspiracy but do not weight motivated biases or official claims differently from people with lower conspiratorial predispositions. The findings indicate the importance of (geopolitical) identities in shaping conspiracy beliefs and highlight some of the constraints facing elites who seek to benefit from the use of conspiracy claims.

News Frame

The policy of free movement—one of the core principles of the European Union—has become increasingly politicized. This makes it more important to understand how attitudes toward free movement are shaped, and the role of the media. The purpose of this study is therefore to investigate how news frames affect attitudes toward free movement, and whether education moderates framing effects. The findings from a survey experiment conducted in seven European countries show that the effects are few and inconsistent across countries. This suggest that these attitudes are not easily shifted by exposure to a single news frame.

Cognitive Sophistication

The COVID-19 pandemic has become more political in the U.S.A. than in similar Western countries, allowing for a novel test of attitude polarization. Furthermore, past work disagrees about the role of cognitive sophistication (relative to ideology) in the formation of science beliefs. We therefore investigated the roles of political ideology and cognitive sophistication in explaining COVID-19 attitudes across the U.S.A. (N=689), the U.K. (N=642), and Canada (N=644). Polarization was greater in the U.S. than in the U.K., but not Canada. Furthermore, in all three countries, cognitive sophistication correlated negatively with misperceptions – and in fact was a stronger predictor than political ideology. We also found no evidence that cognitive sophistication was associated with increased polarization, contrary to identity-protective cognition accounts of motivated reasoning. Thus, although there is some evidence for political polarization, accurate beliefs about COVID-19 were broadly associated with the quality of one’s reasoning regardless of political polarization.

Effective Instrument

We discuss the role of linguistic metaphors as a cognitive frame for the understanding of genetic information processing. The essential similarity between language and genetic information processing has been recognized since the very beginning, and many prominent scholars have noted the possibility of considering genes and genomes as texts or languages. Most of the core terms in molecular biology are based on linguistic metaphors. The processing of genetic information is understood as some operations on text – writing, reading and editing and their specification (encoding/decoding, proofreading, transcription, translation, reading frame). The concept of gene reading can be traced from the archaic idea of the equation of Life and Nature with the Book. Thus, the genetics itself can be metaphorically represented as some operations on text (deciphering, understanding, code-breaking, transcribing, editing, etc.), which are performed by scientists. At the same time linguistic metaphors portrayed gene entities also as having the ability of reading. In the case of such “bio-reading” some essential features similar to the processes of human reading can be revealed: this is an ability to identify the biochemical sequences based on their function in an abstract system and distinguish between type and its contextual tokens of the same type. Metaphors seem to be an effective instrument for representation, as they make possible a two-dimensional description: biochemical by its experimental empirical results and textual based on the cognitive models of comprehension. In addition to their heuristic value, linguistic metaphors are based on the essential characteristics of genetic information derived from its dual nature: biochemical by its substance, textual (or quasi-textual) by its formal organization. It can be concluded that linguistic metaphors denoting biochemical objects and processes seem to be a method of description and explanation of these heterogeneous properties.

Objective: Lingzhu San (LZS) is a traditional Chinese medicine (TCM) prescription which can be effective in treating febrile seizures (FS) and has few researches on the mechanisms. In order to better guide the clinical use of LZS, we used the research ideas and methods of network pharmacology to find the potential core compounds, targets and pathways of LZS in the complex TCM system for the treatment of FS, and predict the mechanism. Materials and Methods: Databases such as BATMAN, TCMSP, TCMID, and SWISS TARGET are used to mine the active compounds and targets of LZS, and the target information of FS was obtained through GENECARDS and OMIM. Using Venny2.1.0 and Cytoscape software to locked the potential core compounds and targets of FS. The R language and ClusterProfiler software package were adopt to enrich and analyze the KEGG and GO pathways of the core targets and the biological processes and potential mechanisms of the core targets were revealed. Results: 187 active compounds and 2113 target proteins of LZS were collected. And 38 potential core compounds, 35 core targets and 775 metabolic and functional pathways were screened which involved in mediating FS. Finally, the role of the core compounds, targets and pivotal pathways of LZS regulated FS in the pathogenesis and therapeutic mechanism of FS was discussed and clarified. Conclusions: In this paper, the multi-compounds, multi-targets and multi-pathways mechanism of LZS in the treatment of FS was preliminarily revealed through the analysis of network pharmacology data, which is consistent with the principle of multi-compounds compatibility of TCM prescriptions and unified treatment of diseases from multiple angles, and it provides a new way for TCM to treat complex diseases caused by multiple factors.

Key Enzyme

: Acid ceramidase (AC), the key enzyme of the ceramide metabolic pathway hydrolyzes pro-apoptotic ceramide to sphingosine, which by the action of sphingosine-1-kinase is metabolized to mitogenic sphingosine-1-phosphate. The intracellular level of AC determines ceramide/sphingosine-1-phosphate rheostat which in turn decides the cell fate. The upregulated AC expression during cancerous condition acts as a “double-edged sword” by converting pro-apoptotic ceramide to anti-apoptotic sphingosine-1-phosphate, wherein on one end, the level of ceramide is decreased and on the other end, the level of sphingosine-1-phosphate is increased, thus altogether aggravating the cancer progression. In addition, cancer cells with upregulated AC expression exhibited increased cell proliferation, metastasis, chemoresistance, radioresistance and numerous strategies were developed in the past to effectively target the enzyme. Gene silencing and pharmacological inhibition of AC sensitized the resistant cells to chemo/radiotherapy thereby promoting cell death. The core objective of this review is to explore AC mediated tumour progression and the potential role of AC inhibitors in various cancer cell lines/models.

This chapter focuses on the role of the dominant player in conservative media, Fox News, during the first year of Donald Trump’s presidency. It looks at three case studies to illustrate how Fox News used its position at the core of the right-wing media ecosystem repeatedly to mount propaganda attacks in support of Trump: the Michael Flynn firing in March 2017, when Fox adopted the “deep state” framing of the entire controversy; the James Comey firing and Robert Mueller appointment in May 2017; when Fox propagated the Seth Rich murder conspiracy; and in October and November, when the arrests of Paul Manafort and guilty plea of Flynn seemed to mark a new level of threat to the president, Fox reframed the Uranium One story as an attack on the integrity of the FBI and Justice Department officials in charge of the investigation.

This chapter examines the development and politics of US energy policy, with an emphasis on three themes: the distribution of authority to regulate energy between national (or federal) and subnational governments, the relationship between energy and environmental policy and regulation, and the role of climate action in energy politics. It reviews patterns of energy production and consumption; provides an overview of national energy politics; and reviews literatures on federalism and energy politics and policy, the increasing integration of energy and environmental policies, and the politics of energy and climate action. The chapter concludes with a discussion of a future research agenda that underscores the significance of political polarization, subnational governance, and technological innovation for understanding US energy policy.

AbstractWe present first results from our study of the host galaxies and environments of quasars in Galaxy And Mass Assembly (GAMA), a multiwavelength photometric and spectroscopic survey for ∼300,000 galaxies over ∼300 deg2, to a limiting magnitude of r ∼ 20 mag. We use a GAIA-selected sample of ∼350 quasars at z < 0.3 in GAMA. For all the quasars, we determine all surrounding GAMA galaxies and measure their star formation (SF) rate and SF history, and the host galaxy morphology and group membership of the quasars. As a comparison sample of inactive galaxies, we use 1000 subsets of galaxies in GAMA, matched in redshift and galaxy stellar mass to the quasars. We find that quasar activity does not depend on the large-scale environment (cluster/group/void), although quasars tend to prefer satellite location in their environment. Compared to inactive galaxies, quasars are preferentially hosted in bulge-dominated galaxies and have higher SF rates, both overall and averaged over the last 10 and 100 Myr. Quasars also have shorter median SF timescales, shorter median time since the last SF burst, and higher metallicity than inactive galaxies. We discuss these results in terms of triggering mechanisms of the quasar activity and the role of quasars in galaxy evolution.
