RESUMO

Research into crop yield and resilience has underpinned global food security, evident in yields tripling in the past 5 decades. The challenges that global agriculture now faces are not just to feed 10+ billion people within a generation, but to do so under a harsher, more variable, and less predictable climate, and in many cases with less water, more expensive inputs, and declining soil quality. The challenges of climate change are not simply to breed for a "hotter drier climate," but to enable resilience to floods and droughts and frosts and heat waves, possibly even within a single growing season. How well we prepare for the coming decades of climate variability will depend on our ability to modify current practices, innovate with novel breeding methods, and communicate and work with farming communities to ensure viability and profitability. Here we define how future climates will impact farming systems and growing seasons, thereby identifying the traits and practices needed and including exemplars being implemented and developed. Critically, this review will also consider societal perspectives and public engagement about emerging technologies for climate resilience, with participatory approaches presented as the best approach.

RESUMO

The short-beaked echidna is an iconic Australian animal and the most-widespread native mammal, inhabiting diverse environments. The cryptic nature of echidnas has limited research into their ecology in most areas; however, from the well-researched and endangered Kangaroo Island echidna population, we understand that the threats include habitat loss, roads, and invasive species. To obtain more information about echidnas Australia-wide, we established the Echidna Conservation Science Initiative (EchidnaCSI) citizen science project. EchidnaCSI calls on members of the public to submit photographs of wild echidnas and learn to identify and collect echidna scats for molecular analysis. To facilitate participation, we developed a smartphone application as well as ongoing social and traditional media activities and community events. In 3 y, more than 9,000 members of the public have downloaded the EchidnaCSI app, collecting 400 scats and submitting over 8,000 sightings of echidnas from across Australia. A subset of submitted scat samples were subjected to DNA extraction and PCR, which validated the approach of using citizen science for scat collection and viability for molecular analysis. To assess the impact of the project through public participation, we surveyed our participants (n = 944) to understand their demographics and motivations for engagement. Survey results also revealed that EchidnaCSI served as a gateway into citizen science more generally for many participants. EchidnaCSI demonstrates the potential for using citizen science approaches to collect high-quality data and material from a cryptic species over a very large geographic area and the considerable engagement value of citizen science research.

RESUMO

In this paper, we explore the recent creation of "iBlastoids," which are 3-D structures that resemble early human embryos prior to implantation which formed via self-organization of reprogrammed adult skin cells. We explore some of the ethical, philosophical, social, and regulatory issues related to this research, with focus particularly on what it means to "anticipate" research outcomes when using novel methods or when serendipitous discoveries are made. We defend the need for reflexive, anticipatory, and deliberative ethical and conceptual work by researchers working in emerging and contentious research domains, in collaboration with interdisciplinary scholars, as well as regulators, funders, and publics.

RESUMO

The Human Genome Project modeled its open science ethos on nematode biology, most famously through daily release of DNA sequence data based on the 1996 Bermuda Principles. That open science philosophy persists, but daily, unfettered release of data has had to adapt to constraints occasioned by the use of data from individual people, broader use of data not only by scientists but also by clinicians and individuals, the global reach of genomic applications and diverse national privacy and research ethics laws, and the rising prominence of a diverse commercial genomics sector. The Global Alliance for Genomics and Health was established to enable the data sharing that is essential for making meaning of genomic variation. Data-sharing policies and practices will continue to evolve as researchers, health professionals, and individuals strive to construct a global medical and scientific information commons.

RESUMO

Meat eating is a common behaviour, despite many people claiming to like, love, and care about animals. The apparent disconnection between not wanting animals to suffer, yet killing them for food, has been termed the 'meat paradox.' In this experimental study (N = 460), participants completed pre-affect, post-affect, meat attachment, and attitude towards animals questionnaires, under two conditions: exposure to the life of an Australian meat lamb, and information about the nutritional benefits of meat. A factorial MANOVA revealed that negative affect was significantly greater when participants were exposed to the meat-animal connection; however, more entrenched attitudes towards animals and attachment to meat remained unaffected. Significant gender effects were found across all variables: most notably, meat attachment differed according to gender, decreasing in women and increasing in men when exposed to the meat-animal condition. Open-ended responses were subjected to content analysis to understand participants' future meat-consumption preferences and accompanying reasoning strategies. Findings from the present study contribute to understanding how cognitive dissonance and inconsistencies are rationalised by meat consumers.

RESUMO

The Bermuda Principles for DNA sequence data sharing are an enduring legacy of the Human Genome Project (HGP). They were adopted by the HGP at a strategy meeting in Bermuda in February of 1996 and implemented in formal policies by early 1998, mandating daily release of HGP-funded DNA sequences into the public domain. The idea of daily sharing, we argue, emanated directly from strategies for large, goal-directed molecular biology projects first tested within the "community" of C. elegans researchers, and were introduced and defended for the HGP by the nematode biologists John Sulston and Robert Waterston. In the C. elegans community, and subsequently in the HGP, daily sharing served the pragmatic goals of quality control and project coordination. Yet in the HGP human genome, we also argue, the Bermuda Principles addressed concerns about gene patents impeding scientific advancement, and were aspirational and flexible in implementation and justification. They endured as an archetype for how rapid data sharing could be realized and rationalized, and permitted adaptation to the needs of various scientific communities. Yet in addition to the support of Sulston and Waterston, their adoption also depended on the clout of administrators at the US National Institutes of Health (NIH) and the UK nonprofit charity the Wellcome Trust, which together funded 90% of the HGP human sequencing effort. The other nations wishing to remain in the HGP consortium had to accommodate to the Bermuda Principles, requiring exceptions from incompatible existing or pending data access policies for publicly funded research in Germany, Japan, and France. We begin this story in 1963, with the biologist Sydney Brenner's proposal for a nematode research program at the Laboratory of Molecular Biology (LMB) at the University of Cambridge. We continue through 2003, with the completion of the HGP human reference genome, and conclude with observations about policy and the historiography of molecular biology.

RESUMO

Prior to the genomic sequencing era, the bible for those working in clinical genetics was McKusick's Mendelian Inheritance in Man (MIM), which appeared in multiple editions between the 1960s and the late 1990s. This catalogue was organized according to general patterns of inheritance and focused on phenotypes. Beginning in the mid-1980s, it was replaced by Online Mendelian Inheritance in Man (OMIM®), a continuously updated catalogue documenting molecular relationships between genetic variation and phenotypic expression. This paper explores this resource's evolution with attention to how disease is distinguished from clinically irrelevant variation and how phenotypic similarities are captured in cases where there is no obvious genotypic association. It is argued that hybrid compromises are encoded into OMIM®; in addition to serving its key original purpose of being a diagnostic catalogue, it also began to record detectable variations in the genome even if they were not known to be associated with phenotypically visible disorders or even phenotypic variations. Although the impacts of geneticization have been well recognized, particularly in popular media, this example allows exploration of some of the historic, epistemic, and methodological causes that underlie tendencies toward disease geneticization in contemporary medicine, while highlighting that such gene-focused strategies may in fact be warranted in some contexts.

RESUMO

BACKGROUND: Contemporary food systems are vast and complex, creating greater distance between consumers and their food. Consequently, consumers are required to put faith in a system of which they have limited knowledge or control. Country of origin labelling (CoOL) is one mechanism that theoretically enables consumer knowledge of provenance of food products. However, this labelling system has recently come under Australian Government review and recommendations for improvements have been proposed. Consumer engagement in this process has been limited. Therefore this study sought to obtain further consumer opinion on the issue of CoOL and to identify the extent to which Australian consumers agree with Australian Government recommendations for improvements. METHODS: A citizens' jury was conducted with a sample of 14 South Australian consumers to explore their perceptions on whether the CoOL system allows them to make informed food choices, as well as what changes (if any) need to be made to enable informed food choices (recommendations). RESULTS: Overall, jurors' perception of usefulness of CoOL, including its ability to enable consumers to make informed food choices, fluctuated throughout the Citizens' Jury. Initially, the majority of the jurors indicated that the labels allowed informed food choice, however by the end of the session the majority disagreed with this statement. Inconsistencies within jurors' opinions were observed, particularly following delivery of information from expert witnesses and jury deliberation. Jurors provided recommendations for changes to be made to CoOL, which were similar to those provided in the Australian Government inquiry. CONCLUSIONS: Consumers in this study engaged with the topical issue of CoOL and provided their opinions. Overall, consumers do not think that the current CoOL system in Australia enables consumers to make informed choices. Recommendations for changes, including increasing the size of the label and the label's font, and standardising its position, were made.

RESUMO

Although Australians on average consume large quantities of meat, their attitudes to farm animal welfare are poorly understood. We know little about how farm animal production is discussed in Australian households or how children learn about the origins of meat. This study consisted of an online survey completed by 225 primary carers throughout Australia recruited through social media. Findings include that conversations about the origin of meat were generally stimulated by meal preparation within the home rather than visits to agricultural shows or similar activities. Parents preferred to initiate conversations with children about meat production before they were 5 years of age. Urban parents were more likely than rural parents to reveal that they were conflicted about eating meat and would be more empathetic to children who chose to stop eating meat. Rural parents were more likely than urban parents to feel that children should eat what they are given and that talking about meat is not a major issue. Both groups felt that it was important that children should know where their food comes from. The findings of this study suggest that parental attitudes to meat production and consumption influence conversations about meat origins with children.

RESUMO

We propose a framework to describe, analyze, and explain the conditions under which scientific communities organize themselves to do research, particularly within large-scale, multidisciplinary projects. The framework centers on the notion of a research repertoire, which encompasses well-aligned assemblages of the skills, behaviors, and material, social, and epistemic components that a group may use to practice certain kinds of science, and whose enactment affects the methods and results of research. This account provides an alternative to the idea of Kuhnian paradigms for understanding scientific change in the following ways: (1) it does not frame change as primarily generated and shaped by theoretical developments, but rather takes account of administrative, material, technological, and institutional innovations that contribute to change and explicitly questions whether and how such innovations accompany, underpin, and/or undercut theoretical shifts; (2) it thus allows for tracking of the organization, continuity, and coherence in research practices which Kuhn characterized as 'normal science' without relying on the occurrence of paradigmatic shifts and revolutions to be able to identify relevant components; and (3) it requires particular attention be paid to the performative aspects of science, whose study Kuhn pioneered but which he did not extensively conceptualize. We provide a detailed characterization of repertoires and discuss their relationship with communities, disciplines, and other forms of collaborative activities within science, building on an analysis of historical episodes and contemporary developments in the life sciences, as well as cases drawn from social and historical studies of physics, psychology, and medicine.

RESUMO

How effectively communities of scientists come together and co-operate is crucial both to the quality of research outputs and to the extent to which such outputs integrate insights, data and methods from a variety of fields, laboratories and locations around the globe. This essay focuses on the ensemble of material and social conditions that makes it possible for a short-term collaboration, set up to accomplish a specific task, to give rise to relatively stable communities of researchers. We refer to these distinctive features as repertoires, and investigate their development and implementation across three examples of collaborative research in the life sciences. We conclude that whether a particular project ends up fostering the emergence of a resilient research community is partly determined by the degree of attention and care devoted by researchers to material and social elements beyond the specific research questions under consideration.

RESUMO

In an article somewhat ironically entitled "Disambiguating Clinical Intentions," Lynn Jansen promotes an idea that should be bewildering to anyone familiar with the literature on the intention/foresight distinction. According to Jansen, "intention" has two commonsense meanings, one of which is equivalent to "foresight." Consequently, questions about intention are "infected" with ambiguity-people cannot tell what they mean and do not know how to answer them. This hypothesis is unsupported by evidence, but Jansen states it as if it were accepted fact. In this reply, we make explicit the multiple misrepresentations she has employed to make her hypothesis seem plausible. We also point out the ways in which it defies common sense. In particular, Jansen applies her thesis only to recent empirical research on the intentions of doctors, totally ignoring the widespread confusion that her assertion would imply in everyday life, in law, and indeed in religious and philosophical writings concerning the intention/foresight distinction and the Principle of Double Effect.

RESUMO

As we move ever closer to the brink of global environmental collapse, it is vital that we work collaboratively and collectively as global, national, and local communities to design multiscale change. Protecting future generations and reversing (or substantively slowing) the current trends require rapid sustainable progress at the required scale. It is more urgent than ever that we understand and more fully realize the power of transdisciplinary (Td) research to support sustainable practice. A defining factor of Td is the focus on collaboration and codesign and the extent that participation and attention to local context is integral to the knowledge building. Specifically, there is greater ability for community knowledge, values, and aspirations to influence and shape research inquiries to effect meaningful change in real-world decision-making and outcomes. Business-as-usual (BAU) approaches that perpetuate unequal knowledge sharing and dismiss other forms of knowledge beyond traditional science no longer suffice. Transdisciplinary approaches seek to achieve and support sustainable change, but the extent of transformation required to meet ecological protection and regenerative sustainability requires very different operating models for knowing and doing science than the limited traditions of positivist science. However, these powerful defaults and operating paradigms are more deeply ingrained than we might realize, and so challenges persist. This article illustrates how Td science differs from typical research paradigms, particularly in terms of the underlying epistemology; the focus on knowledge and/or power; attention to boundaries and scope; and the degree to which local knowledge, context, and community participation underpin the research process. Active conversations are required to better identify and overcome fundamental challenges for science and Td research approaches to support the necessary transformational change. Importantly, we suggest that Indigenous partnerships, knowledge, and values are vital in achieving the potential of Td research to provide transformational interventions to address complex social and environmental issues such as pollution.

RESUMO

The recently issued ISSCR standards in stem cell research recommend registration of human pluripotent stem cell lines (hPSCs). Registration is critical to establishing stem cell provenance and connecting cell lines to data derived on those lines. In this study, we sought to understand common barriers to registration by conducting interviews with forty-eight Australian stem cell stakeholders, including researchers, clinicians, and industry professionals. Australian stem cell researchers do not routinely register their lines, and only a third of those Australian lines captured by an international registry have fully completed the registration process. Most registered Australian cell lines lack complete information about their ethical provenance or key pluripotency characteristics. Incomplete registration is poorly aligned with the goals of open science on which registries are founded. Users also expressed concerns about the quality of the incomplete information provided to the resource. Registration was considered negatively, for instance as a hurdle or barrier to publication, which impacted on user perceptions of usefulness of registration and lowered the likelihood that they would engage with registries to find resources. Broader adoption of registration by journals, and continued advocacy by stem cell societies, will be important levers for awareness and engagement with registration. Although the Australian community represents a small fraction of potential registry users, the results of this study suggest ways for journals, registries, funders, and the international stem cell community to improve registration compliance.

RESUMO

BACKGROUND: Deliberative engagement techniques and citizens' juries are touted as means of incorporating the public into policy decision-making, managing community expectations and increasing commitment to public health policy. This paper reports a study to examine the feasibility of citizens' juries as a means of collecting data to inform public health policy related to food regulation through evaluation of the conduct of a citizens' jury. METHODS: A citizens' jury was conducted with a representative sample of 17 South Australians to explore their willingness to consider the proposition that food and drink advertising and/or sponsorship should be banned at children's sporting events. RESULTS: The results showed that, in relation to the central proposition and evaluation data from the jury, opinion on the proposition remained comparatively stable. Most jurors indicated that they thought that food and drink sponsorship and/or advertising at children's sporting events would have little or no effect on altering children's diet and eating habits, with the proportion increasing during the jury process. Jurors were given evaluation sheets about the content of the jury and the process of the citizens' jury to complete at the end of the session. The evaluation of the citizens' jury process revealed positive perceptions. The majority of jurors agreed that their knowledge of the issues of food and drink sponsorship in children's sport had increased as a result of participation in the citizens' jury. The majority also viewed the decision-making process as fair and felt that their views were listened to. One important response in the evaluation was that all jurors indicated that, if given the opportunity, they would participate in another citizens' jury. CONCLUSIONS: The findings suggest that the citizens' jury increased participant knowledge of the issue and facilitated reflective discussion of the proposition. Citizens' juries are an effective means of gaining insight into public views of policy and the circumstances under which the public will consider food regulation; however a number of issues need to be considered to ensure the successful conduct of a citizens' jury.
