Summary: The study investigated the competition or co-existence of diatom Chaetoceros gracilis and coccolithophore Pleurochrysis Carterae in laboratory conditions. Results showed that monoculture of C. gracilis had higher growth rate and productivity compared to P. carterae. Co-culture resulted in a slower growth rate for P. carterae, with no significant impact on pigment production. Ash content increased at lower silicate concentrations, with SiO2 being the dominant component.

Summary: The phylogenetic relationships among mediophycean diatoms with elliptical valve outline and elevated apices, especially in relation to pennates, have been a subject of interest and debate. This study re-examined the sexual reproduction and auxospore structure of the diatom Biddulphia biddulphiana, identifying unique features but not providing conclusive evidence for the closest extant relatives of basal araphid pennates.

Summary: A new monoraphid diatom genus, Planoplatessa gen. nov., is described based on a detailed morphological investigation, including light and scanning electron microscopy. The new genus is characterized by uniseriate striae on both the raphe and the rapheless valves, a cavum in rapheless valves only, and straight distal raphe ends on the valve face.

Summary: The study found that increased iron availability and warming in the Southern Ocean can significantly enhance nutrient uptake and primary productivity in surface ocean microbial communities, with a greater effect observed under simultaneous iron addition and warming. Furthermore, the dominant diatom Pseudo-nitzschia showed increased abundance under warming conditions, attributed to its up-regulation of iron-conserving photosynthetic processes and improved iron uptake and storage mechanisms. These findings highlight important physiological differences between diatom groups and suggest potential shifts in phytoplankton assemblages and nutrient cycling in iron-limited Southern Ocean ecosystems under warming conditions.

Summary: A new genus of naviculoid diatom, Gandhia gen. nov., was described based on a detailed morphological investigation. This genus differs from other naviculoid diatoms by the presence of an internal siliceous lamina. Further investigations revealed biogeographic patterns and disjuncts between Europe and Asia.

Summary: This study investigates the organization of diatoms and discovers two competing tendencies, possibly controlled by different biological pathways. One tendency is the local organization of triangular lattice pores, while the other tendency is the global pointing of lattice vectors towards a center of symmetry. This competition results in a frustrated triangular lattice with defects concentrated near the center.

Summary: In this study, the organic modifier was used to adjust the morphology and successfully synthesized Bi24Si2O40-Bi2O2SiO3 (BSO) with a three-dimensional flower-like structure. The optimization of morphology promotes the effective formation of heterostructures, organic-mediated morphology growth, and the regulation of heterojunction, which effectively improves the activity of superoxide radicals and holes. The organic-modified MBSO-2 exhibits excellent photocatalytic performance.

Summary: This study tested the applicability of metabarcoding for the ecological status assessment of Hungarian water bodies, comparing its performance to that of morphology-based identification. The results showed that high-throughput sequencing can be a promising alternative method, but discrepancies between the two methods need to be considered.

Summary: The research reveals the potential of biomimetic silica self-organization for synthesizing innovative silica-based nanomaterials, with the use of block copolymer micelles shelled with charged catanionic surfactants directing the silication process. By adjusting the ratios of surfactants, mesoporous silica nanochannel plates with perpendicular orientation were successfully synthesized, laying the groundwork for innovative materials inspired by diatom frustules.

Summary: The study investigates human motion patterns at a large dance event, finding intermittent and persistent motion patterns among participants. It reveals that displacement distributions deviate from exponential distribution and are best fit by a stretched exponential distribution. Although no evidence of Levy walks is found, individuals exhibit directional persistence and superdiffusivity within the scale set by the stadium size.

Summary: Urban heat islands and other phenomena have raised concerns about the outdoor thermal comfort of city residents. Designing urban spaces that ensure and promote pedestrian thermal comfort is a major challenge for large cities. Understanding pedestrian behavior in urban thermal environments is crucial for achieving this goal. However, current research lacks controlled experimentation, which hinders the quantitative modeling of such complex behavior.

Summary: Chronic stress contributes to the onset of type 2 diabetes, but the exact mechanisms are not fully understood. Responses to stress are influenced by various factors and involve a complex network of neurotransmitters and hormones. Stress can also be influenced by behavioral, metabolic, and environmental factors. Therefore, studying the impact of chronic stress on metabolic health is a complex and emergent process.

Summary: This article describes the process of using causal loop diagrams (CLDs) and computational system dynamics models (SDMs) to study and simulate complex problems. By incorporating expert knowledge and converting it into a computational model, we can better understand the interactions and effects of different parts of a system, as well as the outcomes under different conditions. This approach can be applied to a broader range of complex problems and advances the application of computational science methods to biopsychosocial systems.

Summary: Understanding contact patterns in crowd movement is important for assessing infection spread at mass gathering events. This study uses Wi-Fi mobility data from sports and entertainment events in the Johan Cruijff ArenA stadium in Amsterdam to examine contact patterns. The results show that crowd movement at these events is not uniform, but consists of alternating periods of movement and rest. Contact duration distributions are heavy-tailed, which challenges existing models. The study also investigates the impact of heavy-tailed contact duration on infection spread using random walk models, finding that increased contact duration can pose a higher transmission risk than increased contact frequency.

Summary: Evolution of sedimentary assemblages of biogenic sea-ice proxies is not an accurate representation of diverse sea-ice connected communities. Direct observations reveal that commonly used Arctic diatoms and dinoflagellate cysts species as sea-ice proxies are indirectly linked to sea-ice conditions, and the sediment assemblages of these groups overrepresent summertime pelagic blooms. The study also finds certain isoprenoid lipids, previously considered indicators of open water, can be produced in sea-ice.

Summary: The outbreak of the COVID-19 pandemic has led to a surge in protests. This paper proposes a holistic approach to explore the relationship between societal conditions and the emergence of protests during the pandemic. A quantitative analysis comparing protest dynamics in 27 countries is conducted using statistical and computational modelling. The results highlight the need for alternative modelling approaches to better capture the complexity and underlying dynamics of protests.
