Teaching next-generation sequencing to medical students with a portable sequencing device

Bridging Place-Based Astrobiology Education with Genomics, Including Descriptions of Three Novel Bacterial Species Isolated from Mars Analog Sites of Cultural Relevance

Democratizing genomic data science, including bioinformatics, can diversify the STEM workforce and may, in turn, bring new perspectives into the space sciences. In this respect, the development of education and research programs that bridge genome science with "place" and world-views specific to a given region are valuable for Indigenous students and educators. Through a multi-institutional collaboration, we developed an ongoing education program and model that includes Illumina and Oxford Nanopore sequencing, free bioinformatic platforms, and teacher training workshops to address our research and education goals through a place-based science education lens. High school students and researchers cultivated, sequenced, assembled, and annotated the genomes of 13 bacteria from Mars analog sites with cultural relevance, 10 of which were novel species. Students, teachers, and community members assisted with the discovery of new, potentially chemolithotrophic bacteria relevant to astrobiology. This joint education-research program also led to the discovery of species from Mars analog sites capable of producing N-acyl homoserine lactones, which are quorum-sensing molecules used in bacterial communication. Whole genome sequencing was completed in high school classrooms, and connected students to funded space research, increased research output, and provided culturally relevant, place-based science education, with participants naming three novel species described here. Students at St. Andrew's School (Honolulu, Hawai'i) proposed the name Bradyrhizobium prioritasuperba for the type strain, BL16AT, of the new species (DSM 112479T = NCTC 14602T). The nonprofit organization Kauluakalana proposed the name Brenneria ulupoensis for the type strain, K61T, of the new species (DSM 116657T = LMG = 33184T), and Hawai'i Baptist Academy students proposed the name Paraflavitalea speifideiaquila for the type strain, BL16ET, of the new species (DSM 112478T = NCTC 14603T).

The Impact of Experiential Learning in Host-Pathogen Research on Medical Students' Interests and Attitudes towards Microbiology and Immunology

There is a shortage of residents in the infectious diseases (IDs) specialty due to a lack of interest in this field. If the choice of an ID subspecialty is linked to medical school experiences, then how we teach microbiology and immunology could be a factor in the declining interest in the field. We sought to determine whether experiential learning activities on host-pathogen research might improve students' interests and attitudes toward medical microbiology and immunology. Experiential learning of medical students undertaking research project on microbiology/immunology leads to subjective attitude changes (i.e., increased science motivation, confidence, and knowledge) and the development of a new social niche. It also lets students learn new scientific techniques and use novel technological devices, which have an impact in the experiential learning of basic sciences such as microbiology and immunology. The results of this study support the idea of a beneficial effect of experiential learning, which may rekindle interest of medical students in the field of infectious diseases.

Miniaturized DNA Sequencers for Personal Use: Unreachable Dreams or Achievable Goals

The appearance of next generation sequencing technology that features short read length with high measurement throughput and low cost has revolutionized the field of life science, medicine, and even computer science. The subsequent development of the third-generation sequencing technologies represented by nanopore and zero-mode waveguide techniques offers even higher speed and long read length with promising applications in portable and rapid genomic tests in field. Especially under the current circumstances, issues such as public health emergencies and global pandemics impose soaring demand on quick identification of origins and species of analytes through DNA sequences. In addition, future development of disease diagnosis, treatment, and tracking techniques may also require frequent DNA testing. As a result, DNA sequencers with miniaturized size and highly integrated components for personal and portable use to tackle increasing needs for disease prevention, personal medicine, and biohazard protection may become future trends. Just like many other biological and medical analytical systems that were originally bulky in sizes, collaborative work from various subjects in engineering and science eventually leads to the miniaturization of these systems. DNA sequencers that involve nanoprobes, detectors, microfluidics, microelectronics, and circuits as well as complex functional materials and structures are extremely complicated but may be miniaturized with technical advancement. This paper reviews the state-of-the-art technology in developing essential components in DNA sequencers and analyzes the feasibility to achieve miniaturized DNA sequencers for personal use. Future perspectives on the opportunities and associated challenges for compact DNA sequencers are also identified.

The Future of Infectious Diseases Education

The infectious diseases (ID) specialty continues to be in crisis due to a lack of interest by residents in the recruitment pool. It is possible that enhancing and innovating how microbiology is taught in medical school could increase the interest in ID. We need to improve teaching of preclinical medical microbiology and immunology by incorporating advancements in education and learning technologies to reignite the interest in the field. The shortage of ID specialists has important implications in our fight against ID threats such as the current COVID-19 global pandemic. In order to address this problem, we need to perform extensive research to identify the issues that medical learners and trainees are facing as they progress through their medical education towards the ID specialty.
