After nearly 50 years of searching, the vacuum ultraviolet Th nuclear isomeric transition has recently been directly laser excited and measured with high spectroscopic precision. Nuclear clocks based on this transition are expected to be more robust than and may outperform current optical atomic clocks. These clocks also promise sensitive tests for new physics beyond the standard model.

This analysis evaluated progress toward HCV elimination among people with HIV in Australia between 2014 and 2023.
Methods: The CEASE cohort study enrolled adults with HIV with past or current HCV infection (anti-HCV antibody positive) from 14 primary and tertiary clinics.

Objective: To evaluate whether the use of a labor mirror during the active pushing phase of the second stage of labor is associated with a shorter duration of pushing. Additionally, we examined maternal and neonatal outcomes secondary to mirror use versus non-mirror use.
Design: Retrospective observational cohort study.
Premise: There is a general lack of consensus on the best practices for filtering of single-nucleotide polymorphisms (SNPs) and whether it is better to use SNPs or include flanking regions (full "locus") in phylogenomic analyses and subsequent comparative methods.
Methods: Using genotyping-by-sequencing data from 22 species, we assessed the effects of SNP vs. locus usage and SNP retention stringency.
