Reference genomes of root microbes are essential for metagenomic analyses and mechanistic studies of crop root microbiomes. By combining high-throughput bacterial cultivation with metagenomic sequencing, we constructed comprehensive bacterial and viral genome collections from the roots of wheat, rice, maize, and Medicago. The crop root bacterial genome collection (CRBC) significantly expands the quantity and phylogenetic diversity of publicly available crop root bacterial genomes, with 6,699 bacterial genomes (68.9% from isolates) and 1,817 undefined species, expanding crop root bacterial diversity by 290.6%. The crop root viral genome collection (CRVC) contains 9,736 non-redundant viral genomes, with 1,572 previously unreported genus-level clusters in crop root microbiomes. From these, we identified conserved bacterial functions enriched in root microbiomes across soils and host species and uncovered previously unexplored bacteria-virus connections in crop root ecosystems. Together, the CRBC and CRVC serve as valuable resources for investigating microbial mechanisms and applications, supporting sustainable agriculture. © 2025 The Authors

Groundwater treatment residuals are rich in nano-sized metal oxides which have the potential to remove various water contaminants. In this study, hexavalent chromium adsorbents were synthesized from the residuals of a 30,000 m3 d-1 groundwater treatment plant in Taiwan. The effects of acid type and ratio, acid concentration, ultrasonication time, and heating duration on adsorption capacity were examined. Adsorbents synthesized using dual-acid solutions yielded lower adsorption capacities compared to those which used pure acid solutions. Adsorption capacity decreased with higher ultrasonication time and heating duration. Chromium removal was improved with higher ionic strength and lower pH of the solution. Results showed high correlation between experimental data and the Freundlich isotherm (R2 = 0.9607) and the pseudo-second order kinetic model (R2 = 0.9740) suggesting that the dominant mechanism in the adsorption process is chemisorption. The involvement of Fe and Mn species during chromium adsorption was confirmed by the results of energy dispersive X-ray spectroscopy and Fourier transform infrared (FTIR) spectroscopy analyses. © 2017

Zeolite micropattern created from structurally similar hydrophobic Sil-1 and hydrophilic ZSM-5 zeolites, and tested for the immobilization of fluorescein isothiocyanate conjugate bovine serum albumin (BSA-FITC), biotin conjugate bovine serum albumin (Biotin-BSA), Hochest 33342 and rhodamine conjugate α- bungatoxin, were preferentially deposited onto hydrophobic ZSM-5 patterns regardless of the pattern geometry. Being inorganic, the zeolite micropattern does not deteriorate with time and can be readily reused by simply burning away the deposited chemicals and biomolecules. This suggests that compositional micropattern of zeolite could be used to create high resolution array of biomolecules on flat substrate.

AIRPET, an Asian regional air pollution research network, which is coordinated by the Asian Institute of technology, involves six cities: Bandung, Bangkok, Beijing, Chennai, Manila, and Hanoi. One of the objectives of the network is to provide a comprehensive assessment of particulate matter (PM) air quality though monitoring and receptor modeling tools jointly by six research teams in these cities. The results within the scope of this monitoring and modeling objective in phase 1 (2001-2003) were presented. In total, the network collected over 2500 PM_2.5 and PM₁₀ samples from characteristic urban sites. In all these cities the levels of PM₁₀ and PM_2.5 were found high especially during the dry season which the frequently exceeded the EPA standard for PM₁₀ and PM_2.5, especially at the traffic sites. Traffic had the highest PM_2.5 contribution in most cities with the exceptional high share (> 70%) in Manila. Traffic and coal combustion had high contribution in Beijing while NaNO₃ was found high in Hanoi. This is an abstract of a paper presented at the 98th AWMA Annual Conference and Exhibition (Minneapolis, MN 6/21-24/2005).

Plasticrusts manifest as a coating on intertidal rocks due to environmental exposure. They refer to crushed plastic debris that blankets rocks found along intertidal shorelines. This study significantly contributes to a better understanding of the occurrence of these novel plastic formations, shedding light on their potential pathways of formation during the Anthropocene era. The research provides comprehensive insights into the composition, origins, challenges, and effective management strategies for removing coastal plastic litter. The findings of this investigation offer valuable evidence regarding the formation and impact of these recently discovered plastic items in coastal regions, prompting discussions about their formation processes and their effects on the marine ecosystem. Recognizing that these newly emerged plastic litter pose a considerable threat to the marine environment is crucial. With their emergence, we face an environmental challenge, especially concerning the health of coastal ecosystems. Plasticrusts, when degraded, can release microplastics (MPs) and nanoparticles (NPs) into the surrounding environment. These micro- and nano-sized plastic particles pose significant ecological risks as they persist in ecosystems, potentially harming wildlife and entering the food chain, causing widespread environmental contamination. Significantly, it outlines strategies to minimize the impact of this emerging plastic debris and its source. © 2024, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

The enormous amount of short reads generated by the new DNA sequencing technologies call for the development of fast and accurate read alignment programs. A first generation of hash table-based methods has been developed, including Mapping and Assembly with Quality (MAQ), which is accurate, feature rich and fast enough to align short reads from a single individual .However, MAQ does not support gapped alignment for single-end reads, which makes it unsuitable for alignment of longer reads where indels may occur frequently. The speed of MAQ is also a concern when the alignment is scaled up to the resequencing of hundreds of individuals. Therefore, we carried out an in-depth performance analysis of BWA a popular BWT-based aligner and discovered that its performance is significantly better than MAQ although, it has drawbacks regarding execution speed, time complexity and accuracy. Based on those factors we implemented an improved Burrows-Wheeler Alignment algorithm (BWA), anew read alignment package which is original BWT optimized by source code of Ziv-Lempel (LZ-77) sliding window technique and prefix trie string matching, to efficiently search for inexact and exact matches on tandem repeats against a large reference sequence genome. Our analysis show that search speed of improved BWA significantly increased by approximately 1.40 ×faster than MAQ-32 while achieving sufficiently higher accuracy with percent confidence of 96.7 % and 93.0 %. Moreover, it is more efficient to search exact and inexact matches supported by percent error of 0.05 % single ends and 0.04 % for paired end reads also more effective to search for left and right overlap tandem repeat at percent confidence of 88.9%

The measurement of insects is an important component of many entomological applications, including forensic evidence, where larvae size is used as a proxy for developmental stage, and hence time since colonization/death. Current methods for measuring insects are confounded by varying preservation techniques, biased and non-standardized measurements, and often a lack of sample size given practical constraints. Towards enhanced accuracy and precision in measuring live insects to help avoid these variables, and that allows for different measurements to be analyzed, we developed a non-invasive, digital method using widely available free analytical software to measure live blow fly larvae. Using crime scene photographic equipment currently standard in investigation protocols, we measured the live length of 282 Phormia regina larvae. Repeated measurements of maggots, for all instars, were performed for several orientations and images. Most accurate measurements were obtained when maggots were oriented in their natural full extension. Killed specimens resulted in greater length measurements (Mean 1.79 ± 1.11 mm) when compared to live length. Herein, we report a technically simple, fast, and accurate measurement technique adapted for field and lab-based measurements, as well as, a simple linear equation for conversion of live length to standard killed length measurements. We propose this method be utilized for the standardization of forensic entomological evidence collection and development model creation. © 2019 The Authors

Coastal areas are very dynamic and fragile environment, demanding for policies to preserve these areas as materialized in the Resilient Coastal Development program (PKPT) by the Indonesian government. Amongst the targeted area was Timbulsloko Village in Sayung District, Demak Regency, which coastal areas is severely damaged by erosion. This article analyzed the development of the Coastal Community Group (CCG) related to the PKPT program in Timbulsloko village, especially in how the group is empowered to increase the community's resilient in facing the disaster. This study, applied an analytical descriptive method, used the development of the CCG as phenomenon. Primary data was collected through observation and in-depth interviews with stakeholders, accompanying the secondary data. The result shows that the PKPT funding was mostly spent on infrastructure development and used for project management, not for optimizing local economic empowerment. After the completion of the PKPT, there are no actions or following programs to keep the physical results constructed by the CCG. Accordingly, the orientation towards the CCG building capacity for Timbulsloko community's ecological resilience had not been optimally implemented. This study recommended a "putting the last first" policy approach to preparing the local community. The government must play a stronger role in encouraging a self-help local group for strong human development. © 2018 The Authors, published by EDP sciences.
