The urgent need for microbiology literacy in society

Growing microbiology literacy through interdisciplinary approaches to food fermentations and an Indigenous peoples' rights framework

New approaches to microbiology education are needed to ensure equitable representation in microbiology and to build literacy in microbiology and science broadly. To address this goal, we developed a course held at the collegiate level that uniquely integrated microbiology, Indigenous studies, science and technology studies, and arts and performance. The course participants included students in 12 majors across science, engineering, humanities, and arts. The different disciplines of the course intersected around Inuit fermented foods as the basis for discussions on fundamental microbiological principles, the scientific method, food sovereignty, and Indigenous peoples' rights. A diverse array of activities was included, ranging from lectures in microbiology and fermentation, a sauerkraut-making lab, a walk through the Native American contemplative garden, a workshop on Inuit drum making and dance, as well as a performance by Inuit-soul group Pamyua. We propose that a radically interdisciplinary approach and a human rights framework in microbiology education can be a way to enhance microbiology and science literacy for a diverse group of students.

Gamifying Science-Novel Strategies for Bringing Microbiology to the Classroom

Microbes are essential in every environment, with an important role in the fight against climate change. Promoting microbiology literacy, especially among children, is crucial. Our Ibero-American consortium uses gamification to make science and microbiology education engaging, tested through outreach campaigns in Costa Rica, and promoting future campaigns across Latin America.

"The Littlest Creatures that Live Inside Us": Public understandings influencing microbiome-related behaviors

The impact of behaviors on the microbiome, and in turn its effects on health, are increasingly recognized by the scientific and medical communities. Yet little is known about public understandings of the microbiome and the relationships with health. We developed a semi-structured interview tool covering topics from microbiome composition to behavioral factors affecting microbiomes and related health throughout the life course. Drawing on semi-structured interviews conducted in 2021-22 with 32 US women purposefully recruited from 5 demographic categories (with pets, chronic illness, young children, complementary and alternative medicine use, and elders), we explore perspectives on topics including microbiome and diet, medicine use, cleaning practices, and travel. We conducted a thematic analysis, tallied response frequencies of elicited themes, and plotted emerging themes on semantic maps to provide visual representations of connections between concepts, and commonly mentioned metaphors to identify promising new lines of inquiry on public understandings of the microbiome. We observed interconnections between domains, as shown in semantic maps, and examples of ecological and militaristic analogies. Participants used analogies to estimate duration of microbiome disruption and recovery. Metaphors provide scaffolding for organizing new information about the microbiome and influence how people make choices about when and how to kill or promote microbes in their bodies and their environment. Characterizing these public understandings of microbiomes and linkages to health behaviors among different demographic groups is critical to designing and implementing health education and policy and informing future research inquiries in a participatory way through public-research collaborations.

A systematic scoping review reveals that geographic and taxonomic patterns influence the scientific and societal interest in urban soil microbial diversity

Urban green areas provide multiple ecosystem services in cities, mitigating environmental risks and providing a healthier environment for humans. Even if urban ecology has become popular in the last decade, the soil environment with its microbiota, which sustains many other biodiversity layers, remains overlooked. Here, a comprehensive database of scientific papers published in the last 30 years investigating different aspects of soil microbial diversity was built and systematically reviewed. The aim was to identify the taxa, experimental methods and geographical areas that have been investigated, and to highlight gaps in knowledge and research prospects. Our results show that current knowledge on urban soil microbiota remains incomplete, mainly due to the lack of publications on functional aspects, and is biased, in terms of investigated taxa, with most studies focused on Prokaryotes, and geographic representativeness, with the interest focused on a few large cities in the Northern hemisphere. By coupling bibliometrics with statistical modelling we found that soil microbial traits such as biomass and respiration and omics techniques attract the interest of the scientific community while multi-taxa and time-course studies appeal more to the general public.

Microbiome Literacy: Enhancing Public and Academic Understanding Through the 'Microbiome & Health' Online Course

Microorganisms are fundamental to life on Earth, influencing biogeochemical processes, soil fertility, and the health of humans, animals and plants. Human activities have left a remarkable footprint on the environment, including global microbiomes. Enhancing awareness and improving education about microbiome functions can contribute to a sustainable economy and resilient systems. However, public understanding of microbiome science is hindered by misinformation and limited accessible educational resources. To address this, we developed the massive open online course (MOOC) 'Microbiome & Health', available on iMooX.at and YouTube. The course, structured into six units, covers microbiome concepts, methodologies, human and plant microbiomes, antibiotic resistance, and environmental impacts, aligning with the One Health concept and the Sustainable Development Goals of the United Nations. Initial results show that the MOOC provides the means to increase microbiology literacy, with 73.2% external participation and above-average completion rates. Integration as a mandatory component in university courses has improved student performance, halting declining grades and pass rates. This highlights the MOOC's potential to enhance public and academic understanding of microbiome science, fostering informed decisions for sustainable health and environmental stewardship as well as paving the way for new microbiome-based solutions in biotechnology.

Characterization of heat, salt, acid, alkaline, and antibiotic stress response in soil isolate Bacillus subtilis strain PSK.A2

Microbes play an essential role in soil fertility by replenishing the nutrients; they encounter various biotic and abiotic stresses disrupting their cellular homeostasis, which expedites activating a conserved signaling pathway for transient over-expression of heat shock proteins (HSPs). In the present study, a versatile soil bacterium Bacillus subtilis strain PSK.A2 was isolated and characterized. Further, the isolated bacterium was exposed with several stresses, viz., heat, salt, acid, alkaline, and antibiotics. Stress-attributed cellular morphological modifications such as swelling, shrinkage, and clump formation were observed under the scanning electron microscope. The comparative protein expression pattern was studied by SDS-PAGE, relative protein stabilization was assessed by protein aggregation assay, and relative survival was mapped by single spot dilution and colony-counting method under control, stressed, lethal, and stressed lethal conditions of the isolate. The findings demonstrated that bacterial stress tolerance was maintained via the activation of various HSPs of molecular weight ranging from 17 to 115 kD to respective stimuli. The treatment of subinhibitory dose of antibiotics not interfering protein synthesis (amoxicillin and ciprofloxacin) resulted in the expression of eight HSPs of molecular weight ranging from 18 to 71 kD. The pre-treatment of short stress dosage showed endured overall tolerance of bacterium to lethal conditions, as evidenced by moderately enhanced total soluble intracellular protein content, better protein stabilization, comparatively over-expressed HSPs, and relatively enhanced cell survival. These findings hold an opportunity for developing novel approaches towards enhancing microbial resilience in a variety of conditions, including industrial bioprocessing, environmental remediation, and infectious disease management.

Updated ASM Curriculum Guidelines describe core microbiology content to modernize the framework for microbiology education

Curricular guidelines promote standardized approaches to coverage of essential knowledge and skills in undergraduate education. The American Society for Microbiology (ASM) Curriculum Guidelines for Undergraduate Microbiology were developed in 2012. Continuous, rapid growth of knowledge in science and a dynamic, changing world necessitate updates to these guidelines. As such, ASM formed a task force in the summer of 2022. The task force assessed the 2012 ASM Curriculum Guidelines considering advancements in technology, an understanding of an expanded role of microbes, and a broader scope addressing relevant social and environmental aspects of microbiology. Language in the updated guidelines was also modified to better include eukaryotic microbes, viruses, and other acellular microbes. The task force formed working groups, each aimed at revising specific sections of the 2012 ASM Curriculum Guidelines. The revisions to the ASM Curriculum Guidelines were reviewed by subject matter experts and education stakeholders. Feedback from this peer review was incorporated into the updated guidelines, and further comments were solicited from the ASM Conference of Undergraduate Educators (ASMCUE) attendees in November 2023 before these guidelines were finalized. In this article, we describe the rationale and development of updated ASM Curriculum Guidelines which identify foundational concepts that will serve to improve microbial literacy and that can be expanded upon to address more advanced and specialized topics.

Pints of the past, flavours for the future

The recreation of historic beverages is possible via contemporary fermentations carried out with microbes revived form the past. Advanced molecular techniques have recently provided opportunities to investigate historic samples, such as those from beer found in shipwrecks, and provide data on their character as well as identifying differences with contemporary products. In some cases, isolates of yeasts and bacteria create the possibility for authentic recreations of fermented beverages that can have cultural and nostalgic interest. They may also provide insights into the relationship between humans and microbes. The authenticity of recreations, however, can be limited by difficulties in recipe interpretation, differences in water composition and ingredients, possible genetic changes of the retrieved microbes, and from advances in production processes and equipment. Such organisms may also be used to produce novel foods and for other new industrial (non-food) applications. Microorganisms in nature are known to survive geological time-periods. Nevertheless, the survival of some copiotrophic 'fermentation' microbes for a century or more suggests a robust stress biology. Moreover, it facilitates the exciting prospect of recreating fermented products once enjoyed by our predecessors.

Penitentiaries: Bringing microbiological literacy to the fringes of society

This report highlights a science outreach effort for prisons launched by the Spanish National Research Council (CSIC) in collaboration with the NGO Solidarios para el Desarrollo. The Microbiology-focused part of the initiative aims at educating inmates on some basic facts, in order to raise awareness about microorganisms and their impact on daily life. The outline of the talks, inspired by the International Initiative for Microbial Literacy, aims to encourage this collective to move from passive listeners into active participants, helping them understand that Earth is a microbial planet, and that their bodies harbour vast microbiomes that affect their health and social interactions. The talks introduce Microbiology using simple metaphors and emphasize the role of beneficial microorganisms. By explaining the power of microscopes, inmates are shown the hidden microbial world that surrounds them, sparking interest and curiosity. The talks also cover microbial biotechnology, using examples such as bioplastics, anti-cavity bacteria, and skin microorganisms designed for acne prevention. Overall, this outreach initiative seeks to provide inmates with valuable scientific knowledge, fostering curiosity and critical thinking. Despite the challenges of delivering such content in a prison setting, the initiative demonstrates that even marginalized groups can benefit from microbiological literacy, helping them to both endure their terms and eventually reintegrate into society.

Perspectives on the future of ecology, evolution, and biodiversity from the Council on Microbial Sciences of the American Society for Microbiology

The field of microbial ecology, evolution, and biodiversity (EEB) is at the leading edge of understanding how microbes shape our biosphere and influence the well-being of humankind and Earth. To that end, EEB is developing new transdisciplinary tools to analyze these ecologically critical, complex microbial communities. The American Society for Microbiology's Council on Microbial Sciences hosted a virtual retreat in 2023 to discuss the trajectory of EEB both within the Society and microbiology writ large. The retreat emphasized the interconnectedness of microbes and their outsized global influence on environmental and host health. The maximal potential impact of EEB will not be achieved without contributions from disparate fields that unite diverse technologies and data sets. In turn, this level of transdisciplinary efforts requires actively encouraging "broad" research, spanning inclusive global collaborations that incorporate both scientists and the public. Together, the American Society for Microbiology and EEB are poised to lead a paradigm shift that will result in a new era of collaboration, innovation, and societal relevance for microbiology.

Examination of public perceptions of microbes and microbiomes in the United States reveals insights for science communication

Within a changing research and media landscape, misconceptions and misinformation about microorganisms and microbiomes can arise, necessitating improvements in science communication practices through insights in public perceptions of the microbial world. Yet, little is known about public perceptions of microorganisms and microbiomes, making it difficult to develop tailored messaging. Here we perform an inductive thematic analysis with interviews and surveys from thirty adults across the United States to identify key factors to enhance microbial science communication efforts. Together, our results underscore the importance of 1) recognizing the existing and desired future knowledge of an audience, 2) aligning with broader socio-scientific issues that resonate with people in relevant channels using social networks, 3) fostering collaboration between microbiologists, social scientists, and communicators to improve messaging, and 4) appealing to people's values and emotions to establish meaningful connections. This study concludes that non-microbial interests, such as an interest in health and wellness, may lead to acquisition of microbial knowledge and that people want scientists to share microbial messages preferably on platforms like social media. Additionally, we identified confusion about microbial terms and a desire to understand human-centric benefits of microorganisms and microbiomes. We suggest that microbiologists partner with science communicators to develop microbial messaging, capitalizing on connections to non-microbial interests and appealing to people's microbial worldview.

'Tiny Biome Tales': A gamified review about the influence of lifestyle choices on the human microbiome

In the last two decades, new discoveries from microbiome research have changed our understanding of human health. It became evident that daily habits and lifestyle choices shape the human microbiome and ultimately determine health or disease. Therefore, we developed 'Tiny Biome Tales' (https://microbiome.gamelabgraz.at/), a science pedagogy video game designed like a scientific review based exclusively on peer-reviewed articles, to teach about the influence of lifestyle choices on the human microbiome during pregnancy, early and adult life, and related health consequences. Despite the scientific character, it can be played by a broad audience. Here, we also present a scientific assessment and showed that playing the game significantly contributed to knowledge gain. The innovative style of the 'gamified review' represents an ideal platform to disseminate future findings from microbiome research by updating existing and adding new scenes to the game.

This is the Age of Microbial Technology: Crucial roles of learned societies and academies

Microbial technologies constitute a huge and unique potential for confronting major humanitarian and biosphere challenges, especially in the realms of sustainability and providing basic goods and services where they are needed and particularly in low-resource settings. These technologies are evolving rapidly. Powerful approaches are being developed to create novel products, processes, and circular economies, including new prophylactics and therapies in healthcare, bioelectric systems, and whole-cell understanding of metabolism that provides novel insights into mechanisms and how they can be utilised for applications. The modulation of microbiomes promises to create important applications and mitigate problems in a number of spheres. Collectively, microbial technologies save millions of lives each year and have the potential, through increased deployment, to save many more. They help restore environmental health, improve soil fertility, enable regenerative agriculture, reduce biodiversity losses, reduce pollution, and mitigate polluted environments. Many microbial technologies may be considered to be 'healing' technologies - healing of humans, of other members of the biosphere, and of the environment. This is the Age of Microbial Technology. However, the current exploitation of microbial technologies in the service of humanity and planetary health is woefully inadequate and this failing unnecessarily costs many lives and biosphere deterioration. Microbiologists - the practitioners of these healing technologies - have a special, preordained responsibility to promote and increase their deployment for the good of humanity and the planet. To do this effectively - to actually make a difference - microbiologists will need to partner with key enablers and gatekeepers, players such as other scientists with essential complementary skills like bioengineering and bioinformatics, politicians, financiers, and captains of industry, international organisations, and the general public. Orchestration and coordination of the establishment and functioning of effective partnerships will best be accomplished by learned societies, their academies, and the international umbrella organisations of learned societies. Effective dedication of players to the tasks at hand will require unstinting support from employers, particularly the heads of institutes of higher education and of research establishments. Humanity and the biosphere are currently facing challenges to their survival not experienced for millennia. Effectively confronting these challenges is existential, and microbiologists and their learned societies have pivotal roles to play: they must step up and act now.

A concept for international societally relevant microbiology education and microbiology knowledge promulgation in society

EXECUTIVE SUMMARY

Microbes are all pervasive in their distribution and influence on the functioning and well-being of humans, life in general and the planet. Microbially-based technologies contribute hugely to the supply of important goods and services we depend upon, such as the provision of food, medicines and clean water. They also offer mechanisms and strategies to mitigate and solve a wide range of problems and crises facing humanity at all levels, including those encapsulated in the sustainable development goals (SDGs) formulated by the United Nations. For example, microbial technologies can contribute in multiple ways to decarbonisation and hence confronting global warming, provide sanitation and clean water to the billions of people lacking them, improve soil fertility and hence food production and develop vaccines and other medicines to reduce and in some cases eliminate deadly infections. They are the foundation of biotechnology, an increasingly important and growing business sector and source of employment, and the centre of the bioeconomy, Green Deal, etc. But, because microbes are largely invisible, they are not familiar to most people, so opportunities they offer to effectively prevent and solve problems are often missed by decision-makers, with the negative consequences this entrains. To correct this lack of vital knowledge, the International Microbiology Literacy Initiative-the IMiLI-is recruiting from the global microbiology community and making freely available, teaching resources for a curriculum in societally relevant microbiology that can be used at all levels of learning. Its goal is the development of a society that is literate in relevant microbiology and, as a consequence, able to take full advantage of the potential of microbes and minimise the consequences of their negative activities. In addition to teaching about microbes, almost every lesson discusses the influence they have on sustainability and the SDGs and their ability to solve pressing problems of societal inequalities. The curriculum thus teaches about sustainability, societal needs and global citizenship. The lessons also reveal the impacts microbes and their activities have on our daily lives at the personal, family, community, national and global levels and their relevance for decisions at all levels. And, because effective, evidence-based decisions require not only relevant information but also critical and systems thinking, the resources also teach about these key generic aspects of deliberation. The IMiLI teaching resources are learner-centric, not academic microbiology-centric and deal with the microbiology of everyday issues. These span topics as diverse as owning and caring for a companion animal, the vast range of everyday foods that are produced via microbial processes, impressive geological formations created by microbes, childhood illnesses and how they are managed and how to reduce waste and pollution. They also leverage the exceptional excitement of exploration and discovery that typifies much progress in microbiology to capture the interest, inspire and motivate educators and learners alike. The IMiLI is establishing Regional Centres to translate the teaching resources into regional languages and adapt them to regional cultures, and to promote their use and assist educators employing them. Two of these are now operational. The Regional Centres constitute the interface between resource creators and educators-learners. As such, they will collect and analyse feedback from the end-users and transmit this to the resource creators so that teaching materials can be improved and refined, and new resources added in response to demand: educators and learners will thereby be directly involved in evolution of the teaching resources. The interactions between educators-learners and resource creators mediated by the Regional Centres will establish dynamic and synergistic relationships-a global societally relevant microbiology education ecosystem-in which creators also become learners, teaching resources are optimised and all players/stakeholders are empowered and their motivation increased. The IMiLI concept thus embraces the principle of teaching societally relevant microbiology embedded in the wider context of societal, biosphere and planetary needs, inequalities, the range of crises that confront us and the need for improved decisioning, which should ultimately lead to better citizenship and a humanity that is more sustainable and resilient.

ABSTRACT

The biosphere of planet Earth is a microbial world: a vast reactor of countless microbially driven chemical transformations and energy transfers that push and pull many planetary geochemical processes, including the cycling of the elements of life, mitigate or amplify climate change (e.g., Nature Reviews Microbiology, 2019, 17, 569) and impact the well-being and activities of all organisms, including humans. Microbes are both our ancestors and creators of the planetary chemistry that allowed us to evolve (e.g., Life's engines: How microbes made earth habitable, 2023). To understand how the biosphere functions, how humans can influence its development and live more sustainably with the other organisms sharing it, we need to understand the microbes. In a recent editorial (Environmental Microbiology, 2019, 21, 1513), we advocated for improved microbiology literacy in society. Our concept of microbiology literacy is not based on knowledge of the academic subject of microbiology, with its multitude of component topics, plus the growing number of additional topics from other disciplines that become vitally important elements of current microbiology. Rather it is focused on microbial activities that impact us-individuals/communities/nations/the human world-and the biosphere and that are key to reaching informed decisions on a multitude of issues that regularly confront us, ranging from personal issues to crises of global importance. In other words, it is knowledge and understanding essential for adulthood and the transition to it, knowledge and understanding that must be acquired early in life in school. The 2019 Editorial marked the launch of the International Microbiology Literacy Initiative, the IMiLI. HERE, WE PRESENT: our concept of how microbiology literacy may be achieved and the rationale underpinning it; the type of teaching resources being created to realise the concept and the framing of microbial activities treated in these resources in the context of sustainability, societal needs and responsibilities and decision-making; and the key role of Regional Centres that will translate the teaching resources into local languages, adapt them according to local cultural needs, interface with regional educators and develop and serve as hubs of microbiology literacy education networks. The topics featuring in teaching resources are learner-centric and have been selected for their inherent relevance, interest and ability to excite and engage. Importantly, the resources coherently integrate and emphasise the overarching issues of sustainability, stewardship and critical thinking and the pervasive interdependencies of processes. More broadly, the concept emphasises how the multifarious applications of microbial activities can be leveraged to promote human/animal, plant, environmental and planetary health, improve social equity, alleviate humanitarian deficits and causes of conflicts among peoples and increase understanding between peoples (Microbial Biotechnology, 2023, 16(6), 1091-1111). Importantly, although the primary target of the freely available (CC BY-NC 4.0) IMiLI teaching resources is schoolchildren and their educators, they and the teaching philosophy are intended for all ages, abilities and cultural spectra of learners worldwide: in university education, lifelong learning, curiosity-driven, web-based knowledge acquisition and public outreach. The IMiLI teaching resources aim to promote development of a global microbiology education ecosystem that democratises microbiology knowledge.

Microbes and us: microbiology literacy in Greece

Microbes are ubiquitous and provide numerous services to humans and our planet. However, a query arises as to whether these microbial services are valued by the general public especially after unprecedented conditions like the COVID-19 pandemic. In this context a survey was conducted to investigate the concept of microbe in Greece. Thematic analysis of 672 anonymous responses (age range 4-75yo) received for the open-ended prompt "What is the first thing that comes to mind when you hear the word microbe?" revealed five thematic categories: Negative emotions, Fuzzy associations, Biology, Entities and Health. Almost 80% of responses fell under "Biology" and "Health" and the general pattern of answers was the same across all age groups. Microbes took a variety of forms in the minds of respondents, however, the concept of "microbe" seems to be more unshaped at younger ages (4-11yo), as revealed in children's language choices. Overall, the often-negative perception of microorganisms seems to be confirmed in this study. Although this research was limited to participants from Greece, it remains relevant to other countries around the world as well. We discuss the reasons behind this negative perception and offer suggestions for reversing it.

Investigate the relationship between the microbiota awareness in first trimester and high risk pregnancy in Turkish women: cross-sectional study

BACKGROUND

It is suggested that pregnancy risks may be related to microbial dysbiosis, and it is known that knowledge on this subject is reflected in behaviors. The purpose of this study was to investigate whether microbiota awareness in the first trimester of pregnancy is associated with pregnancy-related risks.

METHODS

Within the scope of the study, the microbiota awareness scale was administered to 426 individuals in the first trimester of pregnancy, and information on any diagnosis related to high-risk pregnancy, gestational age, birth weight, and birth height of the newborn was obtained from their file records.

RESULTS

The mean total microbiota awareness score of individuals was 61.38 ± 11.00 (26.00-91.00). The microbiota awareness score (56.85 ± 11.65) was found to be lower in individuals diagnosed with high-risk pregnancy (p < 0.05) than in healthy subjects (63.64 ± 9.94). Moreover, in individuals with high-risk pregnancies, a positive correlation was found between the microbiota awareness score and newborn birth weight and height (p < 0.05).

CONCLUSION

The poor microbiota awareness level in pregnant women is associated with high-risk pregnancy and neonatal growth status.

Openly available illustrations as tools to describe eukaryotic microbial diversity

Microbial life maintains nearly all the support systems that keep the Earth habitable, yet the diversity of this vast microbial world is greatly understudied, misrepresented, and misunderstood. Even what we do know is difficult to communicate broadly because an intuitive grasp of what these tiny organisms are like is abstract, and we lack tools that would help to describe them. In this Essay, we present a series of openly available technical diagrams that illustrate the diverse range of complex body plans of microbial eukaryotes (or "protists"), as well as an illustrated tree to show the vast diversity they encompass and how they are related to the more familiar macroscopic animals, fungi, and plants. These sorts of tools are desperately needed for teaching and communication about the microbial world, which is a pressingly important problem where much improvement is needed.

Food systems microbiome-related educational needs

Within the European-funded Coordination and Support Action MicrobiomeSupport (https://www.microbiomesupport.eu/), the Workshop 'Education in Food Systems Microbiome Related Sciences: Needs for Universities, Industry and Public Health Systems' brought together over 70 researchers, public health and industry partners from all over the world to work on elaborating microbiome-related educational needs in food systems. This publication provides a summary of discussions held during and after the workshop and the resulting recommendations.

Synthetic Biology─High Time to Deliver?

Synthetic biology (SynBio) has attracted like no other recent development the attention not only of Life Science researchers and engineers but also of intellectuals, technology think-tanks, and private and public investors. This is largely due to its promise to propel biotechnology beyond its traditional realms in medicine, agriculture, and environment toward new territories historically dominated by the chemical and manufacturing industries─but now claimed to be amenable to complete biologization. For this to happen, it is crucial for the field to remain true to its foundational engineering drive, which relies on mathematics and quantitative tools to construct practical solutions to real-world problems. This article highlights several SynBio themes that, in our view, come with somewhat precarious promises that need to be tackled. First, SynBio must critically examine whether enough basic information is available to enable the design or redesign of life processes and turn biology from a descriptive science into a prescriptive one. Second, unlike circuit boards, cells are built with soft matter and possess inherent abilities to mutate and evolve, even without external cues. Third, the field cannot be presented as the one technical solution to many grave world problems and so must avoid exaggerated claims and hype. Finally, SynBio should pay heed to public sensitivities and involve social science in its development and growth, and thus change the technology narrative from sheer domination of the living world to conversation and win-win partnership.

Scientific novelty beyond the experiment

Practical experiments drive important scientific discoveries in biology, but theory-based research studies also contribute novel-sometimes paradigm-changing-findings. Here, we appraise the roles of theory-based approaches focusing on the experiment-dominated wet-biology research areas of microbial growth and survival, cell physiology, host-pathogen interactions, and competitive or symbiotic interactions. Additional examples relate to analyses of genome-sequence data, climate change and planetary health, habitability, and astrobiology. We assess the importance of thought at each step of the research process; the roles of natural philosophy, and inconsistencies in logic and language, as drivers of scientific progress; the value of thought experiments; the use and limitations of artificial intelligence technologies, including their potential for interdisciplinary and transdisciplinary research; and other instances when theory is the most-direct and most-scientifically robust route to scientific novelty including the development of techniques for practical experimentation or fieldwork. We highlight the intrinsic need for human engagement in scientific innovation, an issue pertinent to the ongoing controversy over papers authored using/authored by artificial intelligence (such as the large language model/chatbot ChatGPT). Other issues discussed are the way in which aspects of language can bias thinking towards the spatial rather than the temporal (and how this biased thinking can lead to skewed scientific terminology); receptivity to research that is non-mainstream; and the importance of theory-based science in education and epistemology. Whereas we briefly highlight classic works (those by Oakes Ames, Francis H.C. Crick and James D. Watson, Charles R. Darwin, Albert Einstein, James E. Lovelock, Lynn Margulis, Gilbert Ryle, Erwin R.J.A. Schrödinger, Alan M. Turing, and others), the focus is on microbiology studies that are more-recent, discussing these in the context of the scientific process and the types of scientific novelty that they represent. These include several studies carried out during the 2020 to 2022 lockdowns of the COVID-19 pandemic when access to research laboratories was disallowed (or limited). We interviewed the authors of some of the featured microbiology-related papers and-although we ourselves are involved in laboratory experiments and practical fieldwork-also drew from our own research experiences showing that such studies can not only produce new scientific findings but can also transcend barriers between disciplines, act counter to scientific reductionism, integrate biological data across different timescales and levels of complexity, and circumvent constraints imposed by practical techniques. In relation to urgent research needs, we believe that climate change and other global challenges may require approaches beyond the experiment.

Weaponising microbes for peace

There is much human disadvantage and unmet need in the world, including deficits in basic resources and services considered to be human rights, such as drinking water, sanitation and hygiene, healthy nutrition, access to basic healthcare, and a clean environment. Furthermore, there are substantive asymmetries in the distribution of key resources among peoples. These deficits and asymmetries can lead to local and regional crises among peoples competing for limited resources, which, in turn, can become sources of discontent and conflict. Such conflicts have the potential to escalate into regional wars and even lead to global instability. Ergo: in addition to moral and ethical imperatives to level up, to ensure that all peoples have basic resources and services essential for healthy living and to reduce inequalities, all nations have a self-interest to pursue with determination all available avenues to promote peace through reducing sources of conflicts in the world. Microorganisms and pertinent microbial technologies have unique and exceptional abilities to provide, or contribute to the provision of, basic resources and services that are lacking in many parts of the world, and thereby address key deficits that might constitute sources of conflict. However, the deployment of such technologies to this end is seriously underexploited. Here, we highlight some of the key available and emerging technologies that demand greater consideration and exploitation in endeavours to eliminate unnecessary deprivations, enable healthy lives of all and remove preventable grounds for competition over limited resources that can escalate into conflicts in the world. We exhort central actors: microbiologists, funding agencies and philanthropic organisations, politicians worldwide and international governmental and non-governmental organisations, to engage - in full partnership - with all relevant stakeholders, to 'weaponise' microbes and microbial technologies to fight resource deficits and asymmetries, in particular among the most vulnerable populations, and thereby create humanitarian conditions more conducive to harmony and peace.

Challenges for Plant Growth Promoting Microorganism Transfer from Science to Industry: A Case Study from Chile

Research on the plant growth promoting microorganisms (PGPM) is increasing strongly due to the biotechnological potential for the agricultural, forestry, and food industry. The benefits of using PGPM in crop production are well proven; however, their incorporation in agricultural management is still limited. Therefore, we wanted to explore the gaps and challenges for the transfer of biotechnological innovations based on PGPM to the agricultural sector. Our systematic review of the state of the art of PGPM research and knowledge transfer takes Chile as an example. Several transfer limiting aspects are identified and discussed. Our two main conclusions are: neither academia nor industry can meet unfounded expectations during technology transfer, but mutually clarifying their needs, capabilities, and limitations is the starting point for successful collaborations; the generation of a collaborative innovation environment, where academia as well as public and private stakeholders (including the local community) take part, is crucial to enhance the acceptance and integration of PGPM on the way to sustainable agriculture.

A Road to Microbiology Literacy (and More): an Opportunity for a Paradigm Change in Teaching

Microbial activities pervasively impact the wellbeing of all organisms, including humans, and the functioning of the planet itself. In order for society to form informed opinions and take effective actions related to its welfare, it must be able to understand the causes of issues of importance and to appreciate the range of possible responses and their likely effectiveness. Society must become microbiology literate. The International Microbiology Literacy Initiative is creating a comprehensive range of teaching resources that will constitute a child-centric school curriculum of societally relevant microbiology. The core of the teaching resources, the lessons, are somewhat unusual in that each one is designed to be essentially stand-alone, so courses can be individually structured by teachers according to their perception of what is interesting and important for their charges. Moreover, the lessons deal not only with societally pertinent microbial activities, but also discuss and propose discussion of their relevance to sustainable development, of their impact on policies and decisions (personal, community, and national), and of issues of stewardship and stakeholder responsibilities. The class lessons are complemented by other child-centric teaching resources whose functions are to add value, to stimulate pupil imagination and excitement in discovery, to engage pupil interest and enthusiasm for topics like sustainability, climate change, international cooperation, citizen science, etc., and to empower pupils as stakeholders in their microbiology education and as educators and multiplicators.

Microbiology education: a significant path to sustainably improve the human and biosphere condition

In this short piece, I connect the dots between the pervasive influence of microbial activities on our health and that of the planet, including their positive and negative roles in current polycrises, our ability to influence microbes to promote their positive influences and mitigate their negative impacts, the roles of everyone as stewards and stakeholders in personal, family, community, national, and global wellbeing, the need for stewards and stakeholders to possess relevant information in order to fulfil their roles and obligations, and the compelling case for microbiology literacy and introduction of a societally relevant microbiology curriculum in school.

We can do it - Empowering learning

We all need to adapt constantly in order to thrive in our ever-changing complex world. Thus, education and educators need to empower learners to develop a mindset and skills set of lifelong and lifewide learning. Papers from around the globe, reflecting the current drivers in education, were published in the FEMS Microbiology Letters virtual Thematic Issue 'Empowering learning' in October 2023. Its content is reviewed here to provide the context for further discussions within the professional community. The focus is on being inclusive, on lowering and removing barriers to learning, and fostering a sense of belonging. So learning communities can be established and connected in support of learning with and from each other for societal benefit, and this is discussed. Authentic learning approaches are highlighted with respect to the inherent opportunities for learners to take ownership for their learning, yet learn collaboratively, and develop resilience over time. Supporting learners in becoming self-regulated and realizing their full potential is truly worthwhile.

Teaching and learning about respiratory infectious diseases: A scoping review of interventions in K-12 education

The pandemic outbreak of COVID-19 has highlighted an urgent need for infectious disease education for K-12 students. To gather a better understanding of what educational interventions have been conducted and to what effect, we performed a scoping review. We identified and examined 23 empirical researcher- and teacher-designed studies conducted in the last 20 years that have reported on efforts to help K-12 students learn about infectious diseases, with a focus on respiratory transmission. Our review shows studies of educational interventions on this topic are rare, especially with regard to the more population-scale (vs. cellular level) concepts of epidemiology. Furthermore, efforts to educate youth about infectious disease primarily focused on secondary school students, with an emphasis on interactive learning environments to model or simulate both cellular-level and population-level attributes of infectious disease. Studies were only mildly successful in raising science interest, with somewhat stronger findings on helping students engage in scientific inquiry on the biology of infectious diseases and/or community spread. Most importantly, efforts left out critical dimensions of transmission dynamics key to understanding implications for public health. Based on our review, we articulate implications for further research and development in this important domain.

Microbial Journey: Mount Everest to Mars

A rigorous exploration of microbial diversity has revealed its presence on Earth, deep oceans, and vast space. The presence of microbial life in diverse environmental conditions, ranging from moderate to extreme temperature, pH, salinity, oxygen, radiations, and altitudes, has provided the necessary impetus to search for them by extending the limits of their habitats. Microbiology started as a distinct science in the mid-nineteenth century and has provided inputs for the betterment of mankind during the last 150 years. As beneficial microbes are assets and pathogens are detrimental, studying both have its own merits. Scientists are nowadays working on illustrating the microbial dynamics in Earth's subsurface, deep sea, and polar regions. In addition to studying the role of microbes in the environment, the microbe-host interactions in humans, animals and plants are also unearthing newer insights that can help us to improve the health of the host by modulating the microbiota. Microbes have the potential to remediate persistent organic pollutants. Antimicrobial resistance which is a serious concern can also be tackled only after monitoring the spread of resistant microbes using disciplines of genomics and metagenomics The cognizance of microbiology has reached the top of the world. Space Missions are now looking for signs of life on the planets (specifically Mars), the Moon and beyond them. Among the most potent pieces of evidence to support the existence of life is to look for microbial, plant, and animal fossils. There is also an urgent need to deliberate and communicate these findings to layman and policymakers that would help them to take an adequate decision for better health and the environment around us. Here, we present a glimpse of recent advancements by scientists from around the world, exploring and exploiting microbial diversity.

Privacy Risks in Microbiome Research: Public Perspectives before and during a Global Pandemic

We assessed public perspectives of microbiome research privacy risks before and after a nationwide emergency was declared in the United States regarding the Covid-19 pandemic. From January to July of 2020, we conducted an online survey of perceived privacy risks of microbiome research among U.S. adults. Among 3,106 participants (the preemergency group), most expressed that the microbiome posed privacy risks similar to those associated with DNA (60.3%) or medical records (50.6%) and that they would prefer detailed explanations (70.2%) of risk in consent materials. Only 8.9% reported moderate to high familiarity with microbiome privacy risks. In adjusted analyses, individuals who participated in the study after the Covid-19 emergency was declared (the Covid-19 emergency group) were less likely to express that microbiome privacy risks were similar to those of DNA or medical records and more likely to report familiarity with the privacy risks of microbiomes. There was a trend toward increased concern after the Covid-19 emergency was declared (p = 0.053). Overall, the study revealed that many U.S. adults believe that microbiome privacy risks are similar to those associated with DNA or medical records, and they prefer detailed explanations in consent documents. Individuals who participated after the Covid-19 emergency was declared reported greater knowledge of microbiome privacy risks but had more concern.

Priorities for ocean microbiome research

Microbial communities have essential roles in ocean ecology and planetary health. Microbes participate in nutrient cycles, remove huge quantities of carbon dioxide from the air and support ocean food webs. The taxonomic and functional diversity of the global ocean microbiome has been revealed by technological advances in sampling, DNA sequencing and bioinformatics. A better understanding of the ocean microbiome could underpin strategies to address environmental and societal challenges, including achievement of multiple Sustainable Development Goals way beyond SDG 14 'life below water'. We propose a set of priorities for understanding and protecting the ocean microbiome, which include delineating interactions between microbiota, sustainably applying resources from oceanic microorganisms and creating policy- and funder-friendly ocean education resources, and discuss how to achieve these ambitious goals.

Lessons From Insect Fungiculture: From Microbial Ecology to Plastics Degradation

Anthropogenic activities have extensively transformed the biosphere by extracting and disposing of resources, crossing boundaries of planetary threat while causing a global crisis of waste overload. Despite fundamental differences regarding structure and recalcitrance, lignocellulose and plastic polymers share physical-chemical properties to some extent, that include carbon skeletons with similar chemical bonds, hydrophobic properties, amorphous and crystalline regions. Microbial strategies for metabolizing recalcitrant polymers have been selected and optimized through evolution, thus understanding natural processes for lignocellulose modification could aid the challenge of dealing with the recalcitrant human-made polymers spread worldwide. We propose to look for inspiration in the charismatic fungal-growing insects to understand multipartite degradation of plant polymers. Independently evolved in diverse insect lineages, fungiculture embraces passive or active fungal cultivation for food, protection, and structural purposes. We consider there is much to learn from these symbioses, in special from the community-level degradation of recalcitrant biomass and defensive metabolites. Microbial plant-degrading systems at the core of insect fungicultures could be promising candidates for degrading synthetic plastics. Here, we first compare the degradation of lignocellulose and plastic polymers, with emphasis in the overlapping microbial players and enzymatic activities between these processes. Second, we review the literature on diverse insect fungiculture systems, focusing on features that, while supporting insects' ecology and evolution, could also be applied in biotechnological processes. Third, taking lessons from these microbial communities, we suggest multidisciplinary strategies to identify microbial degraders, degrading enzymes and pathways, as well as microbial interactions and interdependencies. Spanning from multiomics to spectroscopy, microscopy, stable isotopes probing, enrichment microcosmos, and synthetic communities, these strategies would allow for a systemic understanding of the fungiculture ecology, driving to application possibilities. Detailing how the metabolic landscape is entangled to achieve ecological success could inspire sustainable efforts for mitigating the current environmental crisis.

Microbial biotechnology to assure national security of supplies of essential resources: energy, food and water, medical reagents, waste disposal and a circular economy

The core responsibility of governments is the security of their citizens, and this means inter alia protecting their safety, nutrition and health. Microbiology and microbial biotechnology have key roles to play in improving supply security of essential resources. In this paper, we discuss the urgent need to fully and immediately exploit existing microbial biotechnologies to maximize supply security of energy, food and medical supplies, and of waste management, and to invest in new research specifically targetting supply security of essential resources.

Spit bubbles, speech bubbles, and COVID-19: creating comics in the age of post-infection India

Positioning this essay at intersection of comics studies, visual literacy studies, and information literacy studies, we investigate an interdisciplinary liaison between crisis in the age of COVID-19 and its awareness campaign through Indian comics. With a focus on awareness programme, Indian artists designed comics to demonstrate their vital position in social engagement through this visual medium. Following impending threats and growing concerns, people of all ages glued themselves to social media, newspapers, and television to keep them updated on the impact of COVID-19. Indian comics e.g. Nagraj Strikes: The Attack of Coronaman (2020), Priya's Mask (2020), Kids, Vaayu, and Corona: Who Wins the Fight? (2020), and 'Be aware of Droplets & Bubbles!!' (2020) aimed to help children comprehend the precautionary steps to be taken to save themselves from getting infected with Coronavirus. While the first three comics showcase spit-bubbles primarily as the source of COVID-19, infusing the content with a tinge of superhero fantasy, 'Be aware of Droplets & Bubbles!!' (2020) unveils the microbiological evolution and mutation of the pathogen in comics format. The objective of the article is to show how Indian comics on COVID-19 can be an advantageous communicative medium to nurture knowledge and edutainment in post-infection India.

‘Superbugs’: raising public awareness of antimicrobial resistance through a pop-up science shop

‘Superbugs: A Pop-up Science Shop’ was a public engagement event in the school summer holidays of 2019, organised by members of Cardiff University’s School of Medicine. We transformed an empty retail unit in the centre of Wales’s largest shopping centre into an interactive and immersive microbiology experience. We facilitated two-way dialogue to impart positive impact on the awareness of antibiotic resistance, while concurrently evaluating the efficacy of an engagement strategy focused on the utilisation of public spaces to attract public demographics diverse to those who would normally engage with conventional science, technology, engineering and mathematics (STEM) outreach. Over the course of 14 days, we welcomed 6,566 visitors, with 67 per cent attending as part of the natural footfall of the shopping centre. We created 1,626 young Antibiotic Resistance Champions, located in over two hundred schools, across many of the most deprived areas in Wales. We imparted a positive impact to our stakeholders, with a significant increase in the knowledge and understanding of the subject of antimicrobial resistance (AMR); 91.7 per cent indicated that they had a better understanding after the event. In this article, we discuss the evolution of ‘Superbugs’ from concept, planning and design, to the logistics of delivering an engagement event of this scale. We focus in particular on the learning outcomes of the project, and on how this will shape the future of our ‘Superbugs’ project, and engagement events beyond.

The darkest microbiome-a post-human biosphere

Microbial technology is exceptional among human activities and endeavours in its range of applications that benefit humanity, even exceeding those of chemistry. What is more, microbial technologists are among the most creative scientists, and the scope of the field continuously expands as new ideas and applications emerge. Notwithstanding this diversity of applications, given the dire predictions for the fate of the surface biosphere as a result of current trajectories of global warming, the future of microbial biotechnology research must have a single purpose, namely to help secure the future of life on Earth. Everything else will, by comparison, be irrelevant. Crucially, microbes themselves play pivotal roles in climate (Cavicchioli et al., Nature Revs Microbiol 17: 569-586, 2019). To enable realization of their full potential in humanity's effort to survive, development of new and transformative global warming-relevant technologies must become the lynchpin of microbial biotechnology research and development. As a consequence, microbial biotechnologists must consider constraining their usual degree of freedom, and re-orienting their focus towards planetary-biosphere exigences. And they must actively seek alliances and synergies with others to get the job done as fast as humanly possible; they need to enthusiastically embrace and join the global effort, subordinating where necessary individual aspirations to the common good (the amazing speed with which new COVID-19 diagnostics and vaccines were developed and implemented demonstrates what is possible given creativity, singleness of purpose and funding). In terms of priorities, some will be obvious, others less so, with some only becoming revealed after dedicated effort yields new insights/opens new vistas. We therefore refrain from developing a priority list here. Rather, we consider what is likely to happen to the Earth's biosphere if we (and the rest of humanity) fail to rescue it. We do so with the aim of galvanizing the formulation and implementation of strategic and financial science policy decisions that will maximally stimulate the development of relevant new microbial technologies, and maximally exploit available technologies, to repair existing environmental damage and mitigate against future deterioration.

Photobiology of the keystone genus Metarhizium

Metarhizium fungi are soil-inhabiting ascomycetes which are saprotrophs, symbionts of plants, pathogens of insects, and participate in other trophic/ecological interactions, thereby performing multiple essential ecosystem services. Metarhizium species are used to control insect pests of crop plants and insects that act as vectors of human and animal diseases. To fulfil their functions in the environment and as biocontrol agents, these fungi must endure cellular stresses imposed by the environment, one of the most potent of which is solar ultraviolet (UV) radiation. Here, we examine the cellular stress biology of Metarhizium species in context of their photobiology, showing how photobiology facilitates key aspects of their ecology as keystone microbes and as mycoinsectides. The biophysical basis of UV-induced damage to Metarhizium, and mechanistic basis of molecular and cellular responses to effect damage repair, are discussed and interpreted in relation to the solar radiation received on Earth. We analyse the interplay between UV and visible light and how the latter increases cellular tolerance to the former via expression of a photolyase gene. By integrating current knowledge, we propose the mechanism through which Metarhizium species use the visible fraction of (low-UV) early-morning light to mitigate potentially lethal damage from intense UV radiation later in the day. We also show how this mechanism could increase Metarhizium environmental persistence and improve its bioinsecticide performance. We discuss the finding that visible light modulates stress biology in the context of further work needed on Metarhizium ecology in natural and agricultural ecosystems, and as keystone microbes that provide essential services within Earth's biosphere.

15 years of microbial biotechnology: the time has come to think big-and act soon

Our epoch is largely characterized by the growing realization and concern about the reality of climate change and environmental deterioration, the surge of global pandemics, the unacceptable inequalities between developed and underdeveloped countries and their unavoidable translation into messy immigration, overpopulation and food crises. While all of these issues have a fundamentally political core, they are not altogether removed from the fact that Earth is primarily a microbial planet and microorganisms are the key agents that make the biosphere (including ourselves) function as it does. It thus makes sense that we bring the microbial world-that is the environmental microbiome-to the necessary multi-tiered conversation (hopefully followed by action) on how to avoid future threats and how to make our globe a habitable common house. Beyond discussion on governance, such a dialogue has technical and scientific aspects that only frontline microbial biotechnology can help to tackle. Fortunately, the field has witnessed the onset of new conceptual and material tools that were missing when the journal started.

Evaluating Knowledge of Human Microbiota among University Students in Jordan, an Online Cross-Sectional Survey

Human microbiota have a significant impact on the health of individuals, and reciprocally, lifestyle choices of individuals have an important effect on the diversity and composition of microbiota. Studies assessing microbiota knowledge among the public are lacking, although it is hypothesized that this knowledge can motivate healthier behavior. Hence, this study aimed to measure microbiota knowledge among university students, and the effect of this knowledge on behavioral beliefs. A descriptive cross-sectional study was conducted among students from various fields of study enrolled at the University of Jordan, using an online questionnaire. The questionnaire consisted of 3 parts: demographics, general knowledge of microbiota, and behavioral beliefs related to microbiota. Four hundred and two responses were collected from verified university students. Participants were divided into two groups depending on whether they took a formal microbiology course (45 h) or not. Results from those two groups were compared using appropriate statistical methods. Results showed that most participants, even those who did not take a formal microbiology course, displayed good knowledge of what microbiota is and how they can be influenced by personal and environmental factors. Participants who took a microbiology course had significantly higher microbiota knowledge scores and were more aware of the effect of antibiotics on microbiota. Participants' behavioral beliefs regarding their antibiotic use, but not their diet and lifestyle choices, were affected by their knowledge of microbiota. The study indicates that disseminating knowledge regarding microbiota and microbiology in general, can improve behaviors related to antibiotic use.

Students’ Interests in Biodiversity: Links with Health and Sustainability

The COVID-19 pandemic has shown that sustainable actions to preserve biodiversity are critical to preventing new microorganisms from harming human health. In this sense, education and encouraging young people’s interest in local biodiversity are crucial to promoting its preservation and sustainability. This research studied the biodiversity interests of 14–15-year-old students in São Paulo State, focusing on the links between biodiversity and human health. The criterion of maximum variation was used to constitute a heterogeneous sample of students. Students answered a four-point Likert questionnaire. The items in this questionnaire were divided into categories related to the interest of young people in biodiversity, and these were analyzed using descriptive and inferential statistics (Wilcoxon test). Categories of biodiversity linked to “health or human utility” were of higher interest to young people than those with no links to human benefits, such as “diversity of organisms”. These findings, along with the literature, showed that young people are interested in biodiversity issues associated with human health. Therefore, teaching biodiversity should reflect on new possibilities for making a more sustainable environment and promoting social and environmental justice, fundamental aspects of promoting and guaranteeing human health.

Microbial Interactions Drive Distinct Taxonomic and Potential Metabolic Responses to Habitats in Karst Cave Ecosystem

The geological role of microorganisms has been widely studied in the karst cave ecosystem. However, microbial interactions and ecological functions in such a dark, humid, and oligotrophic habitat have received far less attention, which is crucial to understanding cave biogeochemistry. Herein, microorganisms from weathered rock and sediment along the Heshang Cave depth were analyzed by random matrix theory-based network and Tax4Fun functional prediction. The results showed that although the cave microbial communities have spatial heterogeneity, differential habitats drove the community structure and diversity. Actinobacteria were predominant in weathered rock, whereas Proteobacteria dominated the sediment. The sediment communities presented significantly higher alpha diversities due to the relatively abundant nutrition from the outside by the intermittent stream. Consistently, microbial interactions in sediment were more complex, as visualized by more nodes and links. The abundant taxa presented more positive correlations with other community members in both of the two networks, indicating that they relied on promotion effects to adapt to the extreme environment. The keystones in weathered rock were mainly involved in the biodegradation of organic compounds, whereas the keystone Nitrospira in sediment contributed to carbon/nitrogen fixation. Collectively, these findings suggest that microbial interactions may lead to distinct taxonomic and functional communities in weathered rock and sediment in the subsurface Heshang Cave.

IMPORTANCE In general, the constant physicochemical conditions and limited nutrient sources over long periods in the subsurface support a stable ecosystem in karst cave. Previous studies on cave microbial ecology were mostly focused on community composition, diversity, and the relationship with local environmental factors. There are still many unknowns about the microbial interactions and functions in such a dark environment with little human interference. Two representative habitats, including weathered rock and sediment in Heshang Cave, were selected to give an integrated insight into microbial interactions and potential functions. The cooccurrence network, especially the subnetwork, was used to characterize the cave microbial interactions in detail. We demonstrated that abundant taxa primarily relied on promotion effects rather than inhibition effects to survive in Heshang Cave. Keystone species may play important metabolic roles in sustaining ecological functions. Our study provides improved understanding of microbial interaction patterns and community ecological functions in the karst cave ecosystem.

Absence makes the mind grow stronger - Educating in a pandemic and beyond

With more than one academic year into the pandemic, it is timely to consider the lessons we learnt, and how they could shape education in the future. Papers from around the globe, reflecting on the directions we took and could take, were published in the FEMS Microbiology Letters virtual Thematic Issue 'Educating in a pandemic and beyond' in October 2021. Its content is reviewed here to facilitate discussions within the professional community. Online platforms and tools, that allowed a rapid emergency response, are covered, as well as enhancing student engagement, complementing and blending in-person activities with online elements for more flexible and accessible learning opportunities, the need for educator training, and improving science literacy overall and microbiology literacy specifically. As we go forward, in order to benefit from blended and flexible learning, we need to select our approaches based on evidence, and mindful of the potential impact on learners and educators. Education did not only continue during the pandemic, but it evolved, leading us into the future.

Visualising an invisible symbiosis

Despite the vast abundance and global importance of plant and microbial species, the large majority go unnoticed and unappreciated by humans, contributing to pressing issues including the neglect of study and research of these organisms, the lack of interest and support for their protection and conservation, low microbial and botanical literacy in society, and a growing disconnect between people and nature. The invisibility of many of these organisms is a key factor in their oversight by society, but also points to a solution: sharing the wealth of visual data produced during scientific research with a broader audience. Here, we discuss how the invisible can be visualised for a public audience, and the benefits it can bring.

SUMMARY

Whether too small, slow or concealed, the majority of species on Earth go unseen by humans. One such rather unobservable group of organisms are the arbuscular mycorrhizal (AM) fungi, who form beneficial symbioses with plants. AM symbiosis is ubiquitous and vitally important globally in ecosystem functioning, but partly as a consequence of its invisibility, it receives disproportionally little attention and appreciation. Yet AM fungi, and other unseen organisms, need not remain overlooked: from decades of scientific research there exists a goldmine of visual data, which if shared effectively we believe can alleviate the issues of low awareness. Here, we use examples from our experience of public engagement with AM symbiosis as well as evidence from the literature to outline the diverse ways in which invisible organisms can be visualised for a broad audience. We highlight outcomes and knock-on consequences of this visualisation, ranging from improved human mental health to environmental protection, making the case for researchers to share their images more widely for the benefit of plants (and fungi and other overlooked organisms), people and planet.

A kiosk survey of perception, attitudes and knowledge (PAK) of Australians concerning microbes, antibiotics, probiotics and hygiene

Issues addressed

To obtain a baseline of public perception, attitudes and knowledge (PAK) of Australians about microbes, antibiotics and hygiene like hand washing and use of probiotics.

Methods

Using a kiosk‐based survey method at the American Museum of Natural History (AMNH), we remotely assayed PAK of Australians through their interaction with the kiosk. The surveys we used had five and seven multiple answer questions and were analysed using standard comparative approaches. We also made comparisons based on gender and on age group for many of the questions.

Results

Our analyses indicate that there is a lack of general understanding of the role of microbes in everyday life among Australians. In addition, we detected some basic misunderstandings about antibiotics. While 80% of the respondents identified penicillin as an antibiotic, up to 30% of the respondents wrongly identified aspirin, Tylenol, valium and Benadryl as antibiotics. We also detected a general lack of knowledge about hand washing hygiene and probiotic use.

Conclusions

Our results from around 700 Australian respondents can serve as a baseline for further PAK assessment of Australians. PAK of Australians with respect to microbes and hand washing hygiene is poor therefore public education is needed. This study should stimulate a better roadmap for public education about microbes, antibiotics, probiotics and hygiene.

So what?

With the recent spread of SARS‐Cov2 and the ensuing Covid19 pandemic and the continuing rise in antimicrobial resistance, the need for assessment PAK of microbes and infectious disease has become acute.

Analysis of university student responses to the pandemic in a formal microbiology assessment

During the coronavirus pandemic, second-year students on the B.Sc. molecular biology and genetics degree at Istanbul Technical University sat an open-ended online exam for a microbiology course in which one of the compulsory questions asked how the course had helped them during the first phase of the pandemic (April–July 2020). Fifty of 69 students gave consent for their (anonymous) responses to be analysed in order to discern any key ways in which their knowledge had been applied. The aim of the study was to investigate whether taking an advanced microbiology course increases understanding of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic and has a positive impact on student behaviours with respect to public health practices. Findings were divided into four major themes: course content (information), application of course content to behavioural change (practice), professionalism and their ‘audience’ whilst at home in lockdown (family and friends). Social distancing, wearing face masks, and hand and surface hygiene were described as important behaviours, with this practice informed by their basic microbiology knowledge. This paper describes a scenario where rote assessment can be used to assess wider scientific literacy with respect to application in society, providing students with an opportunity to incorporate and apply their learning into real-life situations, whilst tutors can assess constructivist learning, conceptual understanding and impact on student behaviour.
