The first fossil longhorn beetles (Coleoptera: Cerambycidae) from Australia.

Longhorn beetles (family Cerambycidae) are globally distributed insects with important ecological roles. Here we present the first discovery of fossil longhorn beetles from Australia. The two new taxa described, Ventiala beattiei gen.

Cry1 resistance in a CRISPR/Cas9-mediated HaCad1 gene knockout strain of the Australian cotton bollworm Helicoverpa armigera conferta (Lepidoptera: Noctuidae).

Background: Helicoverpa armigera is a highly polyphagous species that causes huge losses to agricultural and horticultural crops worldwide. In the cotton industry, H. armigera, including the Australian subspecies Helicoverpa armigera conferta, is largely managed using genetically modified crops that express insecticidal toxins, such as Cry1Ac.

Hepatobiliary organoids derived from leporids support the replication of hepatotropic lagoviruses.

The genus of the family contains some of the most virulent vertebrate viruses known. Lagoviruses infect leporids, such as rabbits, hares and cottontails. Highly pathogenic viruses such as (RHDV1) cause a fulminant hepatitis that typically leads to disseminated intravascular coagulation within 24-72 h of infection, killing over 95 % of susceptible animals.

Inferring the age and environmental characteristics of fossil sites using citizen science.

Not all fossil sites preserve microfossils that can be extracted using acid digestion, which may leave knowledge gaps regarding a site's age or environmental characteristics. Here we report on a citizen science approach that was developed to identify microfossils in situ on the surface of sedimentary rocks. Samples were collected from McGraths Flat, a recently discovered Miocene rainforest lake deposit located in central New South Wales, Australia.

Interventions for the long-term prevention of hereditary angioedema attacks.

Background: Hereditary angioedema (HAE) is a serious and potentially life-threatening condition that causes acute attacks of swelling, pain and reduced quality of life. People with Type I HAE (approximately 80% of all HAE cases) have insufficient amounts of C1 esterase inhibitor (C1-INH) protein; people with Type II HAE (approximately 20% of all cases) may have normal C1-INH concentrations, but, due to genetic mutations, these do not function properly. A few people, predominantly females, experience HAE despite having normal C1-INH levels and C1-INH function (rare Type III HAE).

Failure to learn from failure is mitigated by loss-framing and corrective feedback: A replication and test of the boundary conditions of the tune-out effect.

Do people learn from failure or do they mentally "tune-out" upon failure feedback, which in turn undermines learning? Recent research (Eskreis-Winkler & Fishbach, 2019) has suggested the latter, whereas research in educational and work settings indicates that failure can lead to more learning than can success and error-free performance. We conducted two preregistered experiments to replicate the tune-out effect and to test two potential boundary conditions (N = 520). The tune-out effect fully replicated in those experimental conditions that represented close replications of the original study, underscoring the reliability of the original effect.

Lagovirus Non-structural Protein p23: A Putative Viroporin That Interacts With Heat Shock Proteins and Uses a Disulfide Bond for Dimerization.

The exact function(s) of the lagovirus non-structural protein p23 is unknown as robust cell culture systems for the (RHDV) and other lagoviruses have not been established. Instead, a range of and models have been used to study p23, revealing that p23 oligomerizes, accumulates in the cytoplasm, and possesses a conserved C-terminal region with two amphipathic helices. Furthermore, the positional homologs of p23 in other caliciviruses have been shown to possess viroporin activity.

Screening for insecticide resistance in Australian field populations of Bemisia tabaci (Hemiptera: Aleyrodidae) using bioassays and DNA sequencing.

Background: Species within the Bemisia tabaci cryptic species complex can cause significant crop damage. We used high-throughput amplicon sequencing to identify the species composition and resistance allele genotypes in field populations from cotton fields in Australia. For selected populations, the resistance phenotype was determined in bioassays and compared with sequencing data.

Inducing Error Management Culture - Evidence From Experimental Team Studies.

Field studies indicate that error management culture can be beneficial for organizational performance. The question of whether and how error management culture can be induced remained unanswered. We conducted two experiments with newly formed teams, in which we aimed to induce error management culture and to explore whether we would also find beneficial effects of error management culture on performance in an experimental setting.

A Lagerstätte from Australia provides insight into the nature of Miocene mesic ecosystems.

Reduced precipitation in the Miocene triggered the geographic contraction of rainforest ecosystems around the world. In Australia, this change was particularly pronounced; mesic rainforest ecosystems that once dominated the landscape transformed into the shrublands, grasslands, and deserts of today. A lack of well-preserved fossils has made it difficult to understand the nature of Australian ecosystems before the aridification.

Calicivirus Non-structural Proteins: Potential Functions in Replication and Host Cell Manipulation.

The are a family of viruses with a single-stranded, non-segmented RNA genome of positive polarity. The ongoing discovery of caliciviruses has increased the number of genera in this family to 11 (, , , , , , , , , , and ). Caliciviruses infect a wide range of hosts that include fishes, amphibians, reptiles, birds, and marine and land mammals.

Initiative in Work Teams: Lever between Authentic Leadership and Results.

: The central point of this study is , and we analyzed how the theoretical model of antecedents and consequents of personal initiative contribute to explaining the relationship between team initiative and its antecedents and consequents. Authentic leadership is proposed as the antecedent, and the consequent leads to two types of outcomes, one of which is related to employee well-being, and the other is related to performance. However, little is known about what occurs in this relationship once the focus shifts to the team level.

Chronic Fructose Substitution for Glucose or Sucrose in Food or Beverages and Metabolic Outcomes: An Updated Systematic Review and Meta-Analysis.

Despite the publication of several of meta-analyses in recent years, the effects of fructose on human health remains a topic of debate. We previously undertook two meta-analyses on post-prandial and chronic responses to isoenergetic replacement of fructose for sucrose or glucose in food or beverages (Evans et al. 2017, AJCN 106:506-518 & 519-529).

Culture and differentiation of rabbit intestinal organoids and organoid-derived cell monolayers.

Organoids emulate many aspects of their parental tissue and are therefore used to study pathogen-host interactions and other complex biological processes. Here, we report a robust protocol for the isolation, maintenance and differentiation of rabbit small intestinal organoids and organoid-derived cell monolayers. Our rabbit intestinal spheroid and monolayer cultures grew most efficiently in L-WRN-conditioned medium that contained Wnt, R-spondin and Noggin, and that had been supplemented with ROCK and TGF-β inhibitors.

Environmental gut bacteria in European honey bees (Apis mellifera) from Australia and their relationship to the chalkbrood disease.

We report on aerobic "environmental" bacteria isolated from European honey bees (Apis mellifera). We determined the number of culturable aerobic bacteria in the gut of nurse bees sampled from locations around Australia. Bees from healthy colonies had 107-108 aerobic bacteria per g of bee gut, while bees from colonies with chalkbrood consistently had significantly fewer bacteria (104-105 bacteria per g).

When passions collide: Passion convergence in entrepreneurial teams.

Extant research on passion is replete with individual-level studies. Although team-level studies have emerged, these empirical studies have adopted a static approach. We pivot from the predominant static focus on passion by examining passion convergence, or the dynamic pattern of increasing similarity in passion among members of a team.

Intraindividual variability in identity centrality: Examining the dynamics of perceived role progress and state identity centrality.

Conventionally, identity centrality has been conceived of as a stable and transsituational construct, with situational variability in identity centrality treated as being of little informational value. In contrast to past research, we develop a theoretical model arguing that a portion of within-person variability in identity centrality is systematic and meaningful. Drawing on identity control theory, we examine the within-person relationship flowing from perceived role progress to state identity centrality, which is conventionally viewed as reverse causal at the between-person level.

Calicivirus RNA-Dependent RNA Polymerases: Evolution, Structure, Protein Dynamics, and Function.

The are viruses with a positive-sense, single-stranded RNA genome that is packaged into an icosahedral, environmentally stable protein capsid. The family contains five genera (, , , and ) that infect vertebrates including amphibians, reptiles, birds, and mammals. The RNA-dependent RNA polymerase (RdRp) replicates the genome of RNA viruses and can speed up evolution due to its error-prone nature.

Reciprocal relationships between dispositional optimism and work experiences: A five-wave longitudinal investigation.

Previous research on dispositional optimism has predominantly concentrated on the selection effect of dispositional optimism on predicting work outcomes. Recent research, however, has started to examine the socialization effect of life experiences on fostering dispositional optimism development. Extrapolating primarily from the TESSERA framework of personality development (Wrzus & Roberts, 2017) and the literature on dispositional optimism, the current study represents a first attempt to reconcile the 2 seemingly contrasting perspectives.

On the importance of a motivational agency variable: Being a formal business in developing countries is only helpful for growth if business owners show a high degree of personal initiative.

This article advances the understanding of when and how formal status of small-scale entrepreneurs can contribute to higher growth in comparison to their informal counterparts. Our integrative framework suggests that both formal status and personal initiative (PI) behavior have a common pathway to predict firm growth. More importantly, formal firms improve their growth perspectives only if the entrepreneurs show a high degree of PI.

Restricted Host Specificity of Rabbit Hemorrhagic Disease Virus Is Supported by Challenge Experiments in Immune-compromised Mice ( Mus musculus).

Rabbit hemorrhagic disease virus (RHDV) is a highly contagious calicivirus that causes peracute hemorrhagic fever and frequently kills rabbits before an effective adaptive immune response can be developed. In Australia and New Zealand, RHDV is employed to manage wild European rabbit ( Oryctolagus cuniculus) populations. Although there is no evidence that RHDV replicates in animals other than lagomorphs, the detection of RHDV-specific antibodies and RHDV RNA in mice and other species has raised concerns about the host specificity of the virus.

The effects of work engagement and self-efficacy on personal initiative and performance.

Background: Two popular concepts, work engagement and personal initiative, are different but related constructs. This study is based on and extends the Frese and Fay (2001) model of personal initiative (PI) by including work engagement (WE) and self-efficacy as antecedents of PI, and performance as a consequence.

Method: Two studies (study 1, with a cross-sectional design using N = 396 participants from 22 organizations, and study 2, with a longitudinal design conducted in two waves with N = 118 participants from 15 organizations) test the hypotheses.

Teaching personal initiative beats traditional training in boosting small business in West Africa.

Standard business training programs aim to boost the incomes of the millions of self-employed business owners in developing countries by teaching basic financial and marketing practices, yet the impacts of such programs are mixed. We tested whether a psychology-based personal initiative training approach, which teaches a proactive mindset and focuses on entrepreneurial behaviors, could have more success. A randomized controlled trial in Togo assigned microenterprise owners to a control group ( = 500), a leading business training program ( = 500), or a personal initiative training program ( = 500).

A Motif in the F Homomorph of Rabbit Haemorrhagic Disease Virus Polymerase Is Important for the Subcellular Localisation of the Protein and Its Ability to Induce Redistribution of Golgi Membranes.

(RHDV) is a calicivirus that infects and frequently kills rabbits. Previously, we showed that the RHDV RNA-dependent RNA polymerase (RdRp) is associated with distinct, but yet uncharacterised subcellular structures and is capable of inducing a redistribution of Golgi membranes. In this study, we identified a partially hidden hydrophobic motif that determines the subcellular localisation of recombinant RHDV RdRp in transfected cells.
