Scientists have corrected a recent study published in Nature, which explored the evolutionary relationship between eukaryotes and Asgard archaea, revealing that eukaryotes likely emerged from an Asgard archaeal ancestor. The correction, published online on June 14, 2023, addressed redundancies in the phylogenetic markers used in the original research, according to Nature News (Source 1).
The initial study, which included a phylogenomic analysis, suggested that eukaryotes and the heimdallarchaeial order Hodarchaeales form a monophyletic group. The researchers utilized a set of 57 phylogenetic markers (NM57) to reach their conclusions. However, after publication, the team discovered that three of these markers were partially redundant due to their belonging to paralogous families. Consequently, the dataset was reduced to 54 non-redundant markers, as detailed in the correction.
While the correction focused on the methodology of the archaeal study, other news sources highlighted a range of significant events. Devastating climate-change-fueled wildfires in Chile and Argentina caused widespread destruction and fatalities, impacting ancient forests and raising concerns about government budget cuts, according to multiple news sources summarized by Nature News (Sources 3 & 4). The wildfires resulted in 23 deaths.
Other news included the 20th anniversary of Steve's impactful commencement address at Stanford, which continues to inspire many, as reported by Nature News (Sources 3 & 4). Additionally, the FDA rejected Moderna's mRNA flu vaccine application, sparking surprise and scrutiny, as noted by Nature News (Source 3).
In other international news, Bangladesh held its first election since a period of political unrest, according to journalist Moudud Ahmmed Sujan, as reported by Al Jazeera (Source 5). Prince William concluded his first tour of Saudi Arabia with a visit to a nature reserve focused on endangered species reintroduction, including the Arabian leopard. The Prince also toured AlUla, a historic town with numerous mudbrick houses, according to Al Jazeera (Source 5).
