Early life microbial succession in the gut follows common patterns in humans across the globe.

Characterizing the dynamics of microbial community succession in the infant gut microbiome is crucial for understanding child health and development, but no normative model currently exists. Here, we estimate child age using gut microbial taxonomic relative abundances from metagenomes, with high temporal resolution (±3 months) for the first 1.5 years of life.

Mechanism of Amplified Photoacoustic Effect for Silica-Coated Spherical Gold Nanoparticles.

Plasmonic nanomaterials are effective photoacoustic (PA) contrast agents with diverse biomedical applications. While silica coatings on gold nanoparticles (AuNPs) have been demonstrated to increase PA efficiency, the underlying mechanism remains elusive. Here, we systematically investigated the impact of silica coatings on PA generation under picosecond and nanosecond laser pulses.

Tired of being tired: Black college students' experiences of racial battle fatigue from highly publicized anti-Black violence.

The highly publicized murders of Breonna Taylor, George Floyd, and Ahmaud Arbery in 2020 sparked public outrage and widespread discussion around anti-Black violence. While some studies have examined the effects of anti-Black violence exposure on mental health outcomes, there is a paucity of research that explores how these racially charged events contribute to cumulative stress and "weathering" for Black people, particularly. Informed by racial battle fatigue theory, this in-depth qualitative study explored the lived experiences of 30 Black male and female undergraduate college students (aged 18-28) exposed to highly publicized acts of anti-Black violence.

Interconnected pathways link faecal microbiota plasma lipids and brain activity to childhood malnutrition related cognition.

Malnutrition affects over 30 million children annually and has profound immediate and enduring repercussions. Survivors often suffer lasting neurocognitive consequences that impact academic performance and socioeconomic outcomes. Mechanistic understanding of the emergence of these consequences is poorly understood.
