The ‘Alice in Wonderland’ mechanics of the rejection of (climate) science:simulating coherence by conspiracism

Science strives for coherence. For example, the findings from climate science form a highly coherent body of knowledge that is supported by many independent lines of evidence: greenhouse gas (GHG) emissions from human economic activities are causing the global climate to warm and unless GHG emissions are drastically reduced in the near future, the risks from climate change will continue to grow and major adverse consequences will become unavoidable. People who oppose this scientific body of knowledge because the implications of cutting GHG emissions—such as regulation or increased taxation—threaten their worldview or livelihood cannot provide an alternative view that is coherent by the standards of conventional scientific thinking. Instead, we suggest that people who reject the fact that the Earth’s climate is changing due to greenhouse gas emissions (or any other body of well-established scientific knowledge) oppose whatever inconvenient finding they are confronting in piece-meal fashion, rather than systematically, and without considering the implications of this rejection to the rest of the relevant scientific theory and findings. Hence, claims that the globe “is cooling” can coexist with claims that the “observed warming is natural” and that “the human influence does not matter because warming is good for us.” Coherence between these mutually contradictory opinions can only be achieved at a highly abstract level, namely that “something must be wrong” with the scientific evidence in order to justify a political position against climate change mitigation. This high-level coherence accompanied by contradictory subordinate propositions is a known attribute of conspiracist ideation, and conspiracism may be implicated when people reject well-established scientific propositions

Paleo-Balkan and Slavic Contributions to the Genetic Pool of Moldavians

Moldova has a rich historical and cultural heritage, which may be reflected in the current genetic makeup of its population. To date, no comprehensive studies exist about the population genetic structure of modern Moldavians. To bridge this gap with respect to paternal lineages, we analyzed 37 binary and 17 multiallelic (STRs) polymorphisms on the non-recombining portion of the Y chromosome in 125 Moldavian males. In addition, 53 Ukrainians from eastern Moldova and 54 Romanians from the neighboring eastern Romania were typed using the same set of markers. In Moldavians, 19 Y chromosome haplogroups were identified, the most common being I-M423 (20.8%), R-M17* (17.6%), R-M458 (12.8%), E-v13 (8.8%), RM269* and R-M412* (both 7.2%). In Romanians, 14 haplogroups were found including I-M423 (40.7%), R-M17* (16.7%), RM405 (7.4%), E-v13 and R-M412* (both 5.6%). In Ukrainians, 13 haplogroups were identified including R-M17 (34.0%), I-M423 (20.8%), R-M269* (9.4%), N-M178, R-M458 and R-M73 (each 5.7%). Our results show that a significant majority of the Moldavian paternal gene pool belongs to eastern/central European and Balkan/eastern Mediterranean Y lineages. Phylogenetic and AMOVA analyses based on Y-STR loci also revealed that Moldavians are close to both eastern/central European and Balkan-Carpathian populations. The data correlate well with historical accounts and geographical location of the region and thus allow to hypothesize that extant Moldavian paternal genetic lineages arose from extensive recent admixture between genetically autochthonous populations of the Balkan-Carpathian zone and neighboring Slavic group

Space Weather and Financial Systems: Findings and Outlook. An event co-organised by the European Commission’s Joint Research Centre, the UK Civil Contingencies Secretariat and the NOAA Space Weather Prediction Centre 27 June, 2014, London, UK

Space weather can affect both ground-based and space-borne infrastructures, potentially resulting in failures or service disruptions across the globe and causing damage to equipment and systems. With society having become increasingly reliant on the services these infrastructures provide, a more thorough analysis of the risk due to extreme space weather is warranted. Most studies on the impact of space weather on infrastructures focus on the high-voltage power grid, aviation and communication. A less well-known area of potential vulnerability is the impact of space weather on the financial services sector. Elements of this sector’s operations depend on accurate timing, a service which is increasingly provided by space based – and therefore space weather prone - technologies. The Global Navigation Satellite Systems (GNSS), for example, is commonly used for deriving time stamps for financial transactions. In order to address this topic, the Joint Research Centre of the European Commission, the UK Civil Contingencies Secretariat, and the US National Oceanic and Atmospheric Administration jointly organised the “Space weather and financial services” workshop in London on 27 June 2014. The half-day workshop was attended by 50 representatives of the financial service industry, insurance, European and US government agencies, regulators, academia and the European Commission. The objectives of the workshop were to discuss the potential impact of extreme space weather on financial services, in particular through the effect on timing systems of a loss of GNSS services, and to raise the awareness of this risk in the sector. This report presents the findings of this workshop.JRC.G.5-Security technology assessmen

Violation of a Leggett-Garg inequality using ideal negative measurements in neutron interferometry

We report on an experiment that demonstrates the violation of a Leggett-Garg inequality (LGI) with neutrons. LGIs have been proposed in order to assess how far the predictions of quantum mechanics defy macroscopic realism. With LGIs, correlations of measurements performed on a single system at different times are described. The measured value of K = 1.120 +/- 0.007, obtained in a neutron interferometric experiment, is clearly above the limit K = 1 predicted by macro-realistic theories.Comment: 6 pages, 8 figure

Cross-Modal Search and Exploration of Greek Painted Pottery

This paper focuses on digitally-supported research methods for an important group of cultural heritage objects, the Greek pottery, especially with figured decoration. The design, development and application of new digital methods for searching, comparing, and visually exploring these vases needs an interdisciplinary approach to effectively analyse the various features of the vases, like shape, decoration, and manufacturing techniques, and relationships between the vases. We motivate the need and opportunities by a multimodal representation of the objects, including 3D shape, material, and painting. We then illustrate a range of innovative methods for these representations, including quantified surface and capacity comparison, material analysis, image flattening from 3D objects, retrieval and comparison of shapes and paintings, and multidimensional data visualization. We also discuss challenges and future work in this area.Comment: 14 pages, 10 figures, preprint for a book chapter, supplementary video available at https://youtu.be/x_Xg0vy3nJ

M-band: a safeguard for sarcomere stability?

The sarcomere of striated muscle is a very efficient machine transforming chemical energy into movement. However, a wrong distribution of the generated forces may lead to self-destruction of the engine itself. A well-known example for this is eccentric contraction (elongation of the sarcomere in the activated state), which damages sarcomeric structure and leads to a reduced muscle performance. The goal of this review is to discuss the involvement of different cytoskeletal systems, in particular the M-band filaments, in the mechanisms that provide stability during sarcomeric contraction. The M-band is the transverse structure in the center of the sarcomeric A-band, which is responsible both for the regular packing of thick filaments and for the uniform distribution of the tension over the myosin filament lattice in the activated sarcomere. Although some proteins from the Ig-superfamily, like myomesin and M-protein, are the major candidates for the role of M-band bridges, the exact molecular organisation of the M-band is not clear. However, the protein composition of the M-band seems to modulate the mechanical characteristics of the thick filament lattice, in particular its stiffness, adjusting it to the specific demands in different muscle types. The special M-band design in slow fibers might be part of structural adaptations, favouring sarcomere stability for a continuous contractile activity over a broad working range. In conclusion, we discuss why the interference with M-band structure might have fatal consequences for the integrity of the working sarcomer
