Severe COVID-19 is characterised by a plasma proteomic biomarker signature, indicating innate immune activation, leucocyte–endothelial interactions, and epithelial injury.

Longitudinal and computational analyses reveal an early and temporally stable hippocampal and striatal involvement in reinforcement learning in 6-to-7-year-old children.

Analyses of longitudinal neuroimaging data highlight the importance of social contact for brain health.

Third SARS-CoV-2 vaccination appears to eliminate disparities in anti-Spike antibodies between those who received Pfizer-BioNTech versus Oxford/AstraZeneca for first and second vaccination, but levels remain lower in certain groups such as those on the UK 'Shielded Patient List'.

What can authors and reviewers do to keep common statistical mistakes out of the literature?

In baboon gut microbiota, most pairwise correlations in bacterial abundances are weak and negative, and bacterial correlation patterns are largely shared across hosts, rather than personalized to each hosts.

Longitudinal qPCR-based pertussis surveillance of a low-resource African cohort reveals frequent asymptomatic pertussis infections in both young infants and mothers and suggests possible early warning signals for epidemic outbreaks.

Longitudinal tracking of individual T-cell clones reveals the expansion of pre-existing T-cell memory in response to SARS-CoV-2 infection.

High degree of clonal persistence and excess of inter-individual convergence are observed in human memory B cell repertoires, along with signatures of both negative and positive selection in most abundant clonal lineages.

Reliability and predictability analyses beyond standard measures provide empirically based guidance regarding the design of fear conditioning tasks to assess individual differences and group-level inferences cross-sectionally and longitudinally.
