Interferometric telescope observations of the Jovian moon Io reveal that the floor of the Loki Patera volcano has been resurfaced in two waves, with different starting times and velocities. Volcanic resurfacing on Io Jupiter's moon Io has the biggest active volcano in the Solar System. Inside the volcano, a warm floor surrounds a cool central island. Previous observations have indicated that volcanic resurfacing occurs every one to three years, but telescope observations have insufficient resolution to see how this progresses, and spacecraft observations have not been able to see the entire floor at once. Katherine De Kleer et al . used an occultation of Io by another of Jupiter's moons (Europa) to map the entire floor at a spatial resolution of 2 kilometres, using interferometric telescope observations. They find that the resurfacing happens in two waves, with different starting times and velocities, which then converge around the central island. They interpret the differences between the waves as evidence of either a non-uniformity in the lava or variations in the bulk density of the crust across the volcano. The Jovian moon Io hosts the most powerful persistently active volcano in the Solar System, Loki Patera 1 , 2 . The interior of this volcanic, caldera-like feature is composed of a warm, dark floor covering 21,500 square kilometres 3 surrounding a much cooler central ‘island’ 4 . The temperature gradient seen across areas of the patera indicates a systematic resurfacing process 4 , 5 , 6 , 7 , 8 , 9 , which has been seen to occur typically every one to three years since the 1980s 5 , 10 . Analysis of past data has indicated that the resurfacing progressed around the patera in an anti-clockwise direction at a rate of one to two kilometres per day, and that it is caused either by episodic eruptions that emplace voluminous lava flows or by a cyclically overturning lava lake contained within the patera 5 , 8 , 9 , 11 . However, spacecraft and telescope observations have been unable to map the emission from the entire patera floor at sufficient spatial resolution to establish the physical processes at play. Here we report temperature and lava cooling age maps of the entire patera floor at a spatial sampling of about two kilometres, derived from ground-based interferometric imaging of thermal emission from Loki Patera obtained on 8 March 2015 ut as the limb of Europa occulted Io. Our results indicate that Loki Patera is resurfaced by a multi-phase process in which two waves propagate and converge around the central island. The different velocities and start times of the waves indicate a non-uniformity in the lava gas content and/or crust bulk density across the patera.

Cybersecurity teams rely on signature-based scanners such as Loki, a command-line tool for scanning malware, to identify Indicators of Compromise (IOCs), malicious artifacts, and YARA-rule matches. However, the raw Loki log output delivered as CSV or plaintext is challenging to interpret without additional visualization and correlation tools. Therefore, this research discusses the creation of a web-based dashboard that displays results from the Loki scanner. The project focuses on processing and displaying information collected from Loki’s scans, which are available in log files or CSV format. DIGITRACKER was developed as a proof-of-concept (PoC) to process this data and present it in a user-friendly, visually appealing way, enabling system administrators and cybersecurity teams to monitor potential threats and vulnerabilities effectively. By leveraging modern web technologies and dynamic data visualization, the tool enhances the user experience, transforming raw scan results into a well-organized, interactive dashboard. This approach simplifies the often-complicated task of manual log analysis, making it easier to interpret output data and to support low-budget or resource-constrained cybersecurity teams by transforming raw logs into actionable insights. The project demonstrates the dashboard’s effectiveness in identifying and addressing threats, providing valuable tools for cybersecurity system administrators. Moreover, our evaluation shows that DIGITRACKER can process scan logs containing hundreds of IOC alerts within seconds and supports multiple concurrent users with minimal latency overhead. In test scenarios, the integrated Loki scans were achieved, and the end-to-end pipeline from the end of the scan to the initiation of dashboard visualization incurred an average latency of under 20 s. These results demonstrate improved threat visibility, support structured triage workflows, and enhance analysts’ task management. Overall, the system provides a practical, extensible PoC that bridges the gap between command-line scanners and operational security dashboards, with new scan results displayed on the dashboard faster than manual log analysis. By streamlining analysis and enabling near-real-time monitoring, the PoC tool DIGITRACKER empowers cyber defense initiatives and enhances overall system security.

Sleep is a universally conserved behavior whose origin and evolutionary purpose are uncertain. Using phylogenomics, this article investigates the evolutionary foundations of sleep from a never before used perspective. More specifically, it identifies orthologs of human sleep-related genes in the Lokiarchaeota of the Asgard superphylum and examines their functional role. Our findings indicate that a conserved suite of genes associated with energy metabolism and cellular repair is involved, thus suggesting that sleep plays a primordial role in cellular maintenance. The data cited lend credence to the idea that sleep improves organismal fitness across evolutionary time by acting as a restorative process. Notably, our approach demonstrates that phylogenomics is more useful than standard phylogenetics for clarifying common evolutionary traits. By offering insight into the evolutionary history of sleep and putting forth a novel model framework for sleep research across taxa, these findings contribute to our growing understanding of the molecular foundation of sleep. This study lays the groundwork for further investigations into the importance of sleep in various organisms. Such investigations could have consequences for improving human health and more generally could provide a deeper comprehension of the fundamental processes of life.

Background Loki zupa formula is kind of a traditional medicines which used to treat airway diseases, especially those caused by abnormal phlegm, such as cough, asthma and chronic bronchitis. The study aim was to explore the anti-inflammatory and anti-remodeling effects of Loki zupa by using a cigarette-smoke induced rat model of chronic obstructive pulmonary disease. Methods The rats were divided into five groups: the normal group, the model group, the LZ 4 g/kg and LZ8g/kg group, and the positive control group. Rats were exposed to cigarette smoke for 24 weeks to induce a COPD rat model. Lung function was assessed. Histopathological changes were recorded using Haematoxylin–eosin and Masson’s trichrome staining. Mucus hypersecretion was evaluated by PAS staining. Inflammatory factors were measured in blood serum and bronchial alveolar lavage fluid using an enzyme-linked immunosorbent assay. Malondialdehyde and superoxide dismutase and glutathione S -transferase levels were tested by biochemical methods. Gene expression patterns were evaluated using GN-GeneChip Clariom S Array for rat from Affymetrix. And top upregulated and downregulated genes validated by qPCR. And these genes was also compared with gene transcriptomic data from smoker patients with emphysema and non-smokers in GEO dataset. IL-6/PLAGA2A signalling protein expression was assessed by western blot and immunohistochemistry. TGF-β1and smad2/3 signalling expressions were analysed by western Blot. Results Loki zupa improved COPD rats lung function as compared to the model group and pathological changes including inflammatory cell infiltration and goblet cell metaplasia was alleviated in rats treated with Loki zupa Inflammatory factors IL-6, TNF-α, IL-1β and TGF-β1 decreased while significant increase was observed in blood serum IL-10 content in rats treated with Loki zupa. And IL-6 and TNF-α level in bronchial alveolar lavage fluid showed same expression trend in blood serum, while there was no change in MMP-9 content. It also increased antioxidant enzyme SOD and GPX activity while reducing the lipid peroxidation. Gene microarray analysis showed that there were 355 differentially expressed gene in LZ treated COPD rat lung as compared to model group. Both microarray and qPCR results showed that top differentially expressed genes nxt1 (up regulated) and pla2g2a (down regulated) expression were also reversed by LZ treatment. And protein expression level of IL-6 and pla2g2a was also elevated in CS exposed rats while significant reduction was observed in LZ treated rats. Accordingly, Loki zupa inhibited Collagen-1 upstream protein expression of TGF-β/smad2/3 signalling pathway. Conclusion These results demonstrated that Loki zupa showed protective effects in the lung of the COPD rat model. This mainly because of Loki zupa exerts anti-inflammatory effects by blocking IL-6/pla2g2a signalling and inhibiting inflammatory gene expression and attenuates fibrotic responses by inhibiting TGF-β/smad2/3 signalling pathway.

Caridean shrimp are critical components of sea-grass communities and occasionally harbor parasitic bopyrid isopods, which can negatively impact their hosts. However, the ecological factors that drive infection rates of parasitic bopyrid isopods in host carideans are poorly known. We examined 43,875 carideans belonging to 6 families and 11 genera from 19 shallow-water localities throughout south Florida. Of these, only 114 shrimp (belonging to 5 genera) were found to be infested with bopyrids (an additional 251 had deformed carapaces consistent with recent infestation). We identified 13 bopyrid species (Bopyrina abbreviata, Bopyrinella thorii, Eophrixus subcaudalis, Loki circumsaltanus, Metaphrixus carolii, Ovobopyrus alphezemiotes, Parabopyrella lata, Parabopyrella richardsonae, Parabopyriscus stellatus, Capitetragonia alphei, Probopyrus pandalicola, Schizobopyrina urocaridis, and an unidentified Diplophryxus sp.). Bopyrid infection rates were very low throughout the study area, with mean prevalence of 0.26% (range 0.04–1.48%). Furthermore, each isopod species was only ever recovered from a single host genus, suggesting a high degree of genus-level specificity. At the community level, multivariate analyses (RELATE and BVSTEP) indicated that bopyrid community composition was correlated with host community structure, latitude, and temperature, as well as the relative coverage of the sea grasses Thalassia sp. and Syringodium sp. and the alga Penicillus sp. Only 4 parasite taxa were sufficiently abundant to warrant further analysis at the individual taxon level: B. abbreviata, B. thorii, Diplophryxus sp., and P. pandalicola; stepwise regression indicated that bopyrid infection rates were primarily driven by the abundance of their specific hosts, and secondarily by environmental variables such as temperature and depth, as well as algal and sea-grass community composition.

Information on animal communities inhabiting Neotropical fragmented landscapes is important for developing conservation strategies. The structure of amphibian and reptile communities in six tropical rainforest fragments (<20 ha) and two reference areas in continuous forest at Los Tuxtlas, Mexico was studied. A total of 3,481 individuals of 51 species of amphibians and reptiles were recorded across 12 bimonthly surveys during 2 years. Taxonomic composition was different between the smallest fragments and the reference areas. Six species were exclusive to large undisturbed forest and richness was significantly lower in the five smallest fragments (1.4–6.6 ha) compared with the largest patch, one or both of the reference areas. Amphibian abundance tended to be higher in large areas, while reptiles were more abundant in the five smallest fragments. Craugastor loki and Anolis uniformis were the dominant species in all sites, and particularly in the smaller fragments. Amphibian and reptile richness was positively related to larger patch sizes, deeper leaf litter, closed canopy cover, and higher relative humidity and negatively related to linear patch shape and high temperatures. Abundance of reptiles was positively associated to high temperatures, high density of woody debris, and closed canopy cover; it was negatively affected by linear patch shape, low humidity levels, and steeper slopes. While amphibian and reptile communities were strongly affected in vegetation fragments, these patches retained a considerable number of rainforest species. Fragments up to at least 17 ha have the potential for preserving communities with similar structure to those occurring in large tropical rainforests.
