Summary: Drones have become popular in video capturing, and edited drone videos provide valuable information for cinematography and camera path planning. However, filtering drone clips and extracting camera motions from edited videos is challenging, and existing video search engines cannot accurately return only drone clips. To address this, the proposed approach automatically retrieves drone clips from unlabeled videos based on high-level search queries and introduces a large-scale dataset of edited drone videos for training and validation.

Summary: Tourists' use of drones for vacation purposes is increasing, but there is limited understanding of how they use drones and the nature of the resulting videos. This study analyzed 351 vacation drone videos from an international sample to examine their content, technological aspects, and social practices. The findings reveal significant variations in the production of vacation drone videos depending on the type of video creator, confirming and expanding existing knowledge about drone videography in tourism contexts. The study suggests that destination management organizations should view vacation drone videos as a new form of user-generated content and proactively collaborate with drone videographers to maximize the potential opportunities.

Summary: In this study, a specific and sensitive multiplex PCR method was developed for the detection of the chestnut nut rot pathogen Gnomoniopsis smithogilvyi. The assay reliability was enhanced by optimizing primer annealing temperature and concentration. The detection limit of the assay was low, and there was no cross-reactivity with closely and distantly related fungal species. Significant differences in morphologic and virulence traits were found among different isolates of G. smithogilvyi.

Summary: This study evaluated the antifungal potential of biological control agents (BCAs) and their secreted metabolites against G. smithogilvyi. The results showed that BCAs significantly suppressed the pathogen's growth through the production of volatile and non-volatile compounds. Metabolomics analysis also revealed the presence of antifungal compounds in the BCAs. These findings suggest that BCAs could be an ecological alternative for managing chestnut rot, but further field studies are needed to assess their effectiveness.

Summary: Exogenous RNA polymerase III (pol III) promoters are commonly used to express short hairpin RNA (shRNA). However, their expression can cause toxicity due to saturation of the native miRNA pathway. In this study, the researchers developed a novel strategy to mitigate shRNA-associated toxicity by harnessing native miRNA processing enzymes. They found that using miR30-structured shRNAs resulted in the highest expression and subsequent knockdown of target transcripts. Injection of a vector encoding multiple shRNAs into chicken embryos confirmed that this parallel processing was not toxic. This study provides new opportunities for RNAi-based applications in animal species.
