Shared scientific resources, also known as core facilities, support a significant portion of the research conducted at biomolecular research institutions. The Association of Biomolecular Resource Facilities (ABRF) established the Committee on Core Rigor and Reproducibility (CCoRRe) to further its mission of integrating advanced technologies, education, and communication in the operations of shared scientific resources in support of reproducible research. In order to first assess the needs of the scientific shared resource community, the CCoRRe solicited feedback from ABRF members via a survey. The purpose of the survey was to gain information on how U.S. National Institutes of Health (NIH) initiatives on advancing scientific rigor and reproducibility influenced current services and new technology development. In addition, the survey aimed to identify the challenges and opportunities related to implementation of new reporting requirements and to identify new practices and resources needed to ensure rigorous research. The results revealed a surprising unfamiliarity with the NIH guidelines. Many of the perceived challenges to the effective implementation of best practices (i.e., those designed to ensure rigor and reproducibility) were similarly noted as a challenge to effective provision of support services in a core setting. Further, most cores routinely use best practices and offer services that support rigor and reproducibility. These services include access to well-maintained instrumentation and training on experimental design and data analysis as well as data management. Feedback from this survey will enable the ABRF to build better educational resources and share critical best-practice guidelines. These resources will become important tools to the core community and the researchers they serve to impact rigor and transparency across the range of science and technology.

In cancer genetics, the ability to identify constitutive and low-allelic fraction structural variants (SVs) is crucial. Conventional karyotype and cytogenetics approaches are manually intensive. Microarrays and short-read sequencing cannot detect calls in segmental duplications and repeats, often miss balanced variants, and have trouble finding low-frequency mutations. We describe the use of Bionano Genomics Saphyr platform to comprehensively identify SVs for studying cancer genomes. DNA >100 kbp is extracted, labelled at specific motifs, and linearized through NanoChannel arrays for visualization. Molecule images are digitized and de novo assembled, creating chromosomal arm scale genome maps. Somatic mutations can be identified by running the variant annotation pipeline that compares the cancer sample assembly SVs against >600,000 SVs in Bionano control sample SV database, and against a matched control sample SVs, if avaliable. Also, two new Bionano pipelines leverage these long molecules to identify additional somatic SVs: the copy number variation (CNV) and the molecule mapping pipelines. By examining the coverage-depth of molecules alignment to the public reference, the pipeline can identify megabases long CNVs. Similarly, clusters of split-molecule alignments can reliably find translocations and other rearrangements. We applied this suite of discovery tools to identify SVs in a well-studied melanoma cell line COLO829. We collected data from the tumor and the matched blood cell line, constructed contiguous assemblies (N50 >50 Mbp), and called >6,000 SVs in each genome. Then, we classified 51 as somatic by comparing the tumor and the blood control. The two new pipelines further increased sensitivity to rearrangements, for example they captured a BRAF duplication, and other chromosome-arm CNVs. We apply these thorough approaches to multiple well-studied cancer lines to identify novel SVs missed by previous studies. In conclusion, with one comprehensive platform, Saphyr can discover a broad range of traditionally refractory but relevant SVs, and further improves our understanding of cancer.

In light of an upcoming new era of human expansion in the universe, such as future space travel to Mars, the microbiome of the closed space environment needs to be examined thoroughly to identify the types of microorganisms that can accumulate in this unique environment, how long they persist and survive and their impact on human health and spacecraft infrastructure. As part of this NASA initiative, the viable microbial communities on ISS surfaces from eight different locations over three flight missions, spanning 14 months, were characterized using culture-based techniques, qPCR and amplicon sequencing of the 16S rRNA gene and internal transcribed spacer region using the Illumina platform. Across three flight samplings, K. pneumoniaereads, an opportunistic BSL-2 pathogen, were retrieved during Flight 1 and successively its reads persisted in Flight 2. Subsequently, in Flight 3, most of the locations were inflicted with the presence of this opportunistic pathogen. Other noticeable opportunistic pathogens of all flights were A. baumannii, E. cloacae, S. enterica,and S. sonneias well as some fungi. None of the pathogenic fungi were persistent in any of the locations sampled.
