Wurdi Youang: an Australian Aboriginal stone arrangement with possible solar indications
Wurdi Youang is an egg-shaped Aboriginal stone arrangement in Victoria,
Australia. Here we present a new survey of the site, and show that its major
axis is aligned within a few degrees of east-west. We confirm a previous
hypothesis that it contains alignments to the position on the horizon of the
setting sun at the equinox and the solstices, and show that two independent
sets of indicators are aligned in these directions. We show that these
alignments are unlikely to have arisen by chance, and instead the builders of
this stone arrangement appear to have deliberately aligned the site on
astronomically significant positions.Comment: Accepted by Rock Art Researc

International Consensus Statement on Rhinology and Allergy: Rhinosinusitis
Background: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICARâRS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICARâRSâ2021 as well as updates to the original 140 topics. This executive summary consolidates the evidenceâbased findings of the document. Methods: ICARâRS presents over 180 topics in the forms of evidenceâbased reviews with recommendations (EBRRs), evidenceâbased reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results: ICARâRSâ2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidenceâbased management algorithm is provided. Conclusion: This ICARâRSâ2021 executive summary provides a compilation of the evidenceâbased recommendations for medical and surgical treatment of the most common forms of RS
