title: Largest genome assembly in Brassicaceae: retrotransposon-driven genome expansion and karyotype evolution in Matthiola incana

description: Matthiola incana, commonly known as stock and gillyflower, is a widely grown ornamental plant whose genome is significantly larger than that of other species in the mustard family. However, the evolutionary history behind such a large genome (~2 Gb) is still unknown. Here, we have succeeded in obtaining a high-quality chromosome-scale genome assembly of M. incana by integrating PacBio HiFi reads, Illumina short reads and Hi-C data. The resulting genome consists of seven pseudochromosomes with a length of 1965 Mb and 38 245 gene models. Phylogenetic analysis indicates that M. incana and other taxa of the supertribe Hesperodae represent an early-diverging lineage in the evolutionary history of the Brassicaceae. Through a comparative analysis, we revisited the ancestral Hesperodae karyotype (AHK, n = 7) and found several differences from the well-established ancestral crucifer karyotype (ACK, n = 8) model, including extensive inter- and intra-chromosomal rearrangements. Our results suggest that the primary reason for genome obesity in M. incana is the massive expansion of long terminal repeat retrotransposons (LTR-RTs), particularly from the Angela, Athila and Retand families. CHG methylation modification is obviously reduced in the regions where the highest density of Copia-type LTR-RTs and the lowest density of Gypsy-type LTR-RTs overlap, corresponding to the putative centromeres. Based on insertion times and methylation profiling, recently inserted LTR-RTs were found to have a significantly different methylation pattern compared to older ones.

title: Sinapis genomes provide insights into whole-genome triplication and divergence patterns within tribe Brassiceae

description: Sinapis alba and Sinapis arvensis are mustard crops within the Brassiceae tribe of the Brassicaceae family, and represent an important genetic resource for crop improvement. We performed the de novo assembly of Brassica nigra, S. alba, and S. arvensis, and conducted comparative genomics to investigate the pattern of genomic evolution since an ancient whole-genome triplication event. Both Sinapis species retained evi dence of the Brassiceae whole-genome triplication approximately 20.5 million years ago (Mya), with subge nome dominance observed in gene density, gene expression, and selective constraint. While S. alba diverged from the ancestor of Brassica and Raphanus at approximately 12.5 Mya, the divergence time of S. arvensis and B. nigra was approximately 6.5 Mya. S. arvensis and B. nigra had greater collinearity compared with their relationship to either Brassica rapa or Brassica oleracea. Two chromosomes of S. alba (Sal03 and Sal08) were completely collinear with two ancestral chromosomes proposed in the Ancestral Crucifer Kary otype (ACK) genomic block model, the first time this has been observed in the Brassiceae. These results are consistent with S. alba representing a relatively ancient lineage of the species evolved from the common ancestor of tribe Brassiceae, and suggest that the phylogeny of the Brassica and Sinapis genera requires some revision. Our study provides new insights into the genome evolution and phylogenetic relationships of Brassiceae and provides genomic information for genetic improvement of these plants.

description: This is version 1 of the dataset "Hourly Sub-Metered Energy Use Data from 48 public School Buildings in Oslo, Norway"

Files description:
1) Dataset_buildings_csv_files.zip: A zip containing 48 csv files, one per building with building meta data and time series data. The time series data contain hourly sub-metered energy use data from 48 school buildings located in Oslo, owned and managed by Oslobygg KF. 
2) Plots.zip: ZIP containing 48 .png files with plots of the energy use columns in each building in the csv files
3) README.txt: Description of dataset, csv-files and abbriviations

About dataset:
This dataset contains hourly sub-metered energy use data from 48 school buildings located in Oslo, owned and managed by Oslobygg KF. The dataset consists of one comma-delimited (.csv) file per building, each containing metadata about the building, time series data containing energy use measurements, and local weather data. The length of the dataset varies by building, covering between 1 and 11 years of raw data. Raw data for each building was downloaded in 2023 from Oslobygg KF’s energy surveillance system, Energinet. Only buildings with sufficiently reliable sub-metered heating data were included. This process included manual selection, quality control, relabeling, and cleaning to ensure consistency and accuracy. The dataset includes buildings with both electric heating (electric boilers and/or heat pumps) and district heating. All buildings have sub-metered heating data, and some also include sub-meters for domestic hot water heating and photovoltaic electricity generation. This dataset can be used for several research and engineering purposes, including benchmarking and validation of building simulations, heating disaggregation, energy use time series classification, forecasting of energy loads and flexibility, grid planning, and other modeling activities.

title: A collaborative co-curricular undergraduate research experience on sustainable materials: analysis of biochar using the boehm titration and spectroscopic techniques

description: The use of renewable feedstocks such as biomass aligns with global priorities such as sustainability and climate change. Integrating these materials into experiments helps students understand the real-world relevance of chemistry to addressing environmental challenges. Here, we show that the use of biochar as a renewable feedstock provides an inquiry-based laboratory activity that gives students the opportunity to engage in an authentic investigative process. This activity describes a cocurricular summer workshop carried out with undergraduate students who had no prior research experience. The activity combined the Boehm titration as a chemical method for the analysis of biochar coupled with spectroscopic techniques. The workshop was designed to be collaborative in nature, where students collectively contributed to the overall experimental results and discussion. The motivation for the activity stems from a student undertaking a longer Undergraduate Research Experience (URE) in the form of a summer research placement and based on this work designing a research experience workshop that could be rolled out to benefit a larger number of students. We believe this approach of using longer or individual UREs to develop research-focused initiatives could be readily adopted by other UREs to promote and develop research skills.

title: Heterogeneous Fenton-type oxidative degradation of low-density polyethylene to valuable acid products using a nanostructured Fe–CeO2 solid solution catalyst

description: The chemical conversion of waste plastic polymers to useful commodity chemicals has become crucial to helping tackle the issue of global plastic waste today. Polyolefins maintain the highest production rate and lowest recycling rate worldwide due to their inert chemical structures. This work shows the synthesis of solid-solution Fe–CeO2 catalyst as an excellent heterogeneous catalyst for Fenton-type oxidative degradation of low-density polyethylene to achieve high yields of organic acids. The catalyst was synthesized in 3 molar ratios of Fe : Ce and it was found that the molar ratio of iron and cerium was crucial for catalytic performance with the Fe–CeO2 1 : 1 catalyst giving the highest yields of acid products. The catalyst achieved 91% mass loss and 71% organic acid at pH 7, with 1 wt% catalyst loading. The use of a multi-metal Fenton system resulted in a synergistic effect, displaying superior activity to systems with only one Fenton active metal. The heterogeneous nature of the catalyst allowed for easy recovery and demonstrated excellent recyclability in multiple cycles. The high recyclability performance was attributed to the stability of the solid solution structure.
