Using genetics, it is possible to uncouple higher adiposity from its adverse metabolic effects and show that some obesity-associated conditions may benefit from treating the metabolic effects alone, whilst others may benefit more from weight loss.

3% of >1,000 asymptomatic healthcare workers in their workplace tested positive for SARS-CoV-2, suggesting that comprehensive screening programmes are vital to prevent acquisition of COVID-19 in hospitals.

It is unclear how much a child's BMI at age 8 affects their depressive and ADHD symptoms after family-level factors are accounted for, but a substantial impact on anxiety symptoms is unlikely.

A naturally acquired human monoclonal antibody recognizes proteins expressed at different stages of the Plasmodium falciparum life cycle through affinity-matured homotypic interactions with glutamate-rich repeats.

The rapid and gradual fin whale songs changes adopted by individuals of a certain area provide evidence of vocal learning in this species, elucidate patterns of song evolution and hints on the limits of song variation.

Breast luminal epithelial cells are the hotspots of aging-associated changes, which prime aged epithelia for oncogenic gene activation and may explain individual differences in breast cancer susceptibility due to the aging-associated increase in gene expression variances in luminal epithelia.

The ability to adjust body size in response to diet is greater in Drosophila females than males because of a sex difference in the nutrient-dependent regulation of the insulin pathway.

Excitatory cortical neurons with a shared developmental lineage are transcriptomically diverse and preferentially connect to each other vertically, across cortical layers, but not laterally within the same layer.

Mesoderm-derived enteric neurons born in the post-natal vertebrates drive maturation and aging of the enteric nervous system.

Nosocomial transmission of SARS-Cov-2 in geriatric settings is complex, with different patterns between patients and healthcare workers working in Covid/non-Covid wards that should be taken into account when designing infection control strategies.
