Pregnancy is a unique phase in a woman's life marked by profound physical transformations, including changes in body shape and weight. The Body Understanding Measure for Pregnancy Scale (BUMPs) was designed to assess body image during pregnancy. Despite its increasing use, the scale has not yet been adapted into Italian, and evidence regarding its predictive validity with respect to anxiety, depression, and body appreciation is lacking.

- Two polyploid grass weeds in Australia, Hordeum glaucum and Bromus diandrus, have developed resistance to glyphosate through the amplification of the EPSPS gene, which is crucial for their survival.
- Research involved analyzing the EPSPS gene's genomic structure using molecular cytogenetic methods, showing that resistant plants have significantly more copies of the gene compared to susceptible ones.
- The findings suggest that unequal crossover during meiosis may be responsible for the gene duplication, contributing to the evolution of glyphosate resistance in these weed species.
Citizen science represents an important opportunity for school students to make real-world connections with science through context-based learning with the potential to increase their engagement, enjoyment and understanding of science. However, to date, citizen science has not experienced wide uptake in school settings and there is a paucity of information about its implementation in the classroom. Here we present a mixed-method approach investigating teachers' knowledge and use of citizen science in Australian classrooms.

Weeds with resistance to 2,4-D and other auxinic herbicides have evolved, including several populations of Sonchus oleraceus from multiple sites in Australia. We report the underlying mechanism in these populations that gives rise to auxinic herbicide resistance.

Intra-procedural adrenocorticotropic hormone (ACTH), conventionally administered as a 250-μg bolus and/or 50 μg per hour infusion, increases cortisol and aldosterone secretion and can improve AVS success, but may cause discordant lateralisation compared to unstimulated AVS.
Aims: To assess if AVS performed with ultra-low dose ACTH infusion causes discordant lateralisation.
