Summary: The study reports the discovery of an unidentified instrumental signature in the Kepler/K2 observations and suggests that systematic errors may affect the study of active galactic nuclei. The presence of nonastrophysical low-frequency trends and time-delay variations with respect to the detector center radius enhances the complexity of the data analysis.

Summary: Researchers have found a rapid increase in the frequency of symbolic artifacts in the Old World paleolithic record -40-45,000 BP. Correcting the record for taphonomic bias does not change this peak, but suggests it may be a product of research bias. Small peaks at -65,000, 75,000, and 115-120,000 BP are also observed, but their existence might also be influenced by research bias. Understanding the effects of taphonomic and research bias is important.

Summary: This study examines the Hotelling-Smithies game with elastic demand using numerical simulation. The simulation technique allows for monitoring the accuracy of available analytical solutions, such as the monopolistic model, and exploring scenarios where analytical solutions are not easily obtainable. It is found that in games with variable location and price or with variable location and fixed price, the simulated locations tend to drift towards the center, consistent with Hotelling's theory.

Summary: This study investigated whether Aristolochic acids (AAs) were the main cause of liver cancer in the context of HBV infection in mainland China. The results showed that long-term administration of AAs barely increased liver tumorigenesis in adult mice, opposite from its tumor-inducing role in infant mice. Furthermore, AAI induced dose-dependent accumulation of AA-DNA adduct in target organs in adult mice, with the most detected in the kidney instead of the liver. Overall, the data suggest that AA exposure is not a major threat of liver cancer in adulthood.

Summary: Earth's earliest continental crust, dominated by tonalite-trondhjemite-granodiorite (TTG) suites, provides important insights into the global geodynamic regime during the Archaean period. The tectonic setting of TTG magmatism is controversial, with debates on whether subduction was involved. Petrological modeling suggests that high geothermal gradients in hot subduction zones produce Ba-rich TTG, indicating the onset of subduction. Analysis of Ba contents in TTG suites worldwide reveals significant increases from regional to global subduction events occurring between 4 Ga and 2.7 Ga.

Summary: Human capital is the integration of innate skills and knowledge acquired through investing in individual formation, which pays off in the long term. In the Italian legal system, a person is recognized from birth, determining the acquisition of personal rights. While a fetus does not possess these rights by law, it has the innate potential to acquire them after birth.

Summary: This study aimed to test whether the reported increase in frontolateral 40 Hz power during lucid REM sleep is due to the saccadic spike potential artifact. The results showed that lucid dreams are associated with higher physiological activation during REM sleep. Increases in 40 Hz power were attributed to the increased REM density accompanying heightened activation.

Summary: Thin arborescent lycopsid axes belonging to the genus Sigiltaria were discovered in Inner Mongolia, China, showing major differences from previously known taxa. Two new morphospedes, Sigillaria pfefferkornii sp. nov. and Sigillaria wudensis sp. nov., were identified among the thin axes, indicating more diversity in the Permian Sigillaria species in Cathaysia than previously understood. The study provides insights into evaluating early and late ontogenetic stages of plants and highlights the lack of an accurate search image for juvenile arborescent lycopsids.

Summary: The study of insect herbivory in fossil record lacks a quantitative framework, and estimates of damage type diversity are generated with inconsistent sampling standardization routines. Coverage-based rarefaction has been shown to yield valid and reliable estimates of damage type diversity that are robust to differences among floral assemblages. A theoretical ecospace combining various metrics has the potential to distinguish between potential causes of increased herbivory.

Summary: Prototaxites is one of the most enigmatic terrestrial fossils, forming massive treelike or columnar structures. The debate over its affinities has lasted for over 150 years, with the most widely accepted interpretation being that it is a fungus. However, recent research suggests the possibility that it represents a lichen. The authors argue against interpretations as an agaricomycete sporocarp or ascomycete lichen association, and suggest that if it is indeed of fungal origin, it may belong to an extinct lineage.

Summary: A new species of the botryopterid genus Diodonopteris, Diodonopteris virgulata, is described based on a well-preserved specimen from the early Permian Wuda Tuff Flora in Inner Mongolia, China. The new species shares similarities with the type species, D. gracilis, but differs in cortex structure and xylem strand morphology. Both D. virgulata and its host plant are confirmed as climbers, suggesting the complexity of early Permian ecosystems.

Summary: The evolution of high-productivity angiosperms has been considered as a driver for the restructuring of ecosystems during the Mesozoic period. However, the availability of rock-derived nutrients such as phosphorus limits terrestrial productivity, and permanent increases in weathering would violate the mass balance requirements of the long-term carbon cycle. This study provides evidence supporting the potential reality of sustained productivity increases since the Mesozoic through the documentation of a significant increase in the evolution of nitrogen-fixing or nitrogen-scavenging symbioses. The authors also explore how enhanced phosphorus availability could be sustained without violating mass balance requirements using carbon cycle modeling.

Summary: Evolutionary events may have impacts on the geological carbon cycle, but the suggested causes often predate the environmental effects they are linked to. This poses challenges for resolving carbon cycle perturbations within a million years. Preservational filtering can affect the sampling of fossil records, leading to a time lag between the occurrence of an evolutionary lineage and its first appearance in the fossil record.

Summary: The study results do not support the previously proposed mechanisms for the extended gap in the fossil record of winged insects, including sampling bias, preservation bias, and body size. The inference of an early origin of Pterygota, long before their first appearance in the fossil record, is likely an analytical artefact of taxon sampling and choice of fossil calibration points, possibly compounded by heterogeneity in rates of sequence evolution or speciation, including radiations or 'bursts' during their early history.

Summary: The terrestrial biota plays a crucial role in the long-term carbon cycle through the formation of coal and other sedimentary organic matter, as well as the impact on weathering of silicate minerals. However, there are misconceptions that hinder progress in understanding these processes, such as mass balance requirements, the nature and duration of perturbations, timescale constraints, and the role of models.

Summary: The success of various lineages is partly due to changes in vegetation. The evolutionary history of ants is closely associated with the evolution and spread of flowering plants. This study investigates the diversification of ants in relation to flowering plants and biome evolution, focusing on their expansion from forested to non-forested biomes and the relationship between climatic niche evolution and arboreal nesting. The spread of ants into non-forested biomes during the Paleogene-Neogene era was likely driven by the evolution and expansion of arid-adapted angiosperms, providing food for ants. The choice of nesting location in trees is linked to evolutionary innovations in angiosperm physiology and the establishment of everwet tropical rainforests. Differences in climatic optima and climate niche evolution are also associated with nesting location, with arboreal nesters preferring warmer and less seasonal climates and exhibiting slower rates of climatic niche evolution. This research offers new insights into the impact of flowering plant evolution on the ecology and evolution of associated lineages.
