Late fluid flow in a primitive asteroid revealed by Lu–Hf isotopes in Ryugu

Analysis of samples from the asteroid Ryugu provide evidence of late fluid flow in a carbonaceous asteroid, indicating that such bodies may have retained two to three times more water than previously thought.

Carbonate record of temporal change in oxygen fugacity and gaseous species in asteroid Ryugu

The asteroid Ryugu experienced aqueous alteration under changing temperature and redox conditions, according to an isotopic analysis of secondary calcite and dolomite grains in samples from Ryugu obtained by the Hayabusa2 spacecraft.

Contribution of Ryugu-like material to Earth’s volatile inventory by Cu and Zn isotopic analysis

A comparison of copper and zinc isotopic measurements between the Ryugu samples and various carbonaceous chondrites excludes any genetic link between the two except for the CI (Ivuna-type) chondrites. Ryugu-like material might have accounted for ~5% of Earth’s mass.

Apoptotic epithelial cells control the abundance of T_reg cells at barrier surfaces

Epithelia continually undergo apoptosis, but the physiological importance of this is unclear. Shibuya and colleagues show that apoptotic epithelial cells bind the glycoprotein CD300a on a dendritic cell subset at barrier surfaces and this negatively regulates commensal-driven T_reg cell proliferation.

Attenuated fusogenicity and pathogenicity of SARS-CoV-2 Omicron variant

In vitro studies in human cell lines and in vivo studies in a hamster model show that the SARS-CoV-2 Omicron variant is less pathogenic than both the Delta variant and an ancestral strain of SARS-CoV-2.

A multi-ethnic meta-analysis identifies novel genes, including ACSL5, associated with amyotrophic lateral sclerosis

Gen Sobue, Masao Nagasaki and colleagues report a genome-wide association study for amyotrophic lateral sclerosis (ALS) in a large, multi-ethnic cohort comprising Japanese, Chinese, and European ancestry populations. They find a significant association to variants within the ACSL5 gene and identify novel associations with 4 additional genes using a gene-based approach.
