A global comparison of surface and subsurface microbiomes reveals large-scale biodiversity gradients, and a marine-terrestrial divide.

Subsurface environments are among Earth's largest habitats for microbial life. Yet, until recently, we lacked adequate data to accurately differentiate between globally distributed marine and terrestrial surface and subsurface microbiomes. Here, we analyzed 478 archaeal and 964 bacterial metabarcoding datasets and 147 metagenomes from diverse and widely distributed environments.

Bgee in 2024: focus on curated single-cell RNA-seq datasets, and query tools.

Bgee (https://www.bgee.org/) is a database to retrieve and compare gene expression patterns in multiple animal species.

Impact of targeted neonatal echocardiography consultations for critically sick preterm neonates.

Rationale: Preterm neonates needing rescue treatments with inotropes and/or inhaled nitric oxide (iNO) (acute critical illnesses, ACIs) in neonatal intensive care units (NICUs) are at high risk of mortality. While targeted neonatal echocardiography consultations (TNE) are increasingly used to guide management, its clinical impact need evaluation.

Objectives: To investigate clinical outcomes in relation to TNE utilisation during episodes of ACIs among preterm neonates.

Metatranscriptomic response of deep ocean microbial populations to infusions of oil and/or synthetic chemical dispersant.

Oil spills are a frequent perturbation to the marine environment that has rapid and significant impacts on the local microbiome. Previous studies have shown that exposure to synthetic dispersant alone did not enhance heterotrophic microbial activity or oxidation rates of specific hydrocarbon components but increased the abundance of some taxa (e.g.
