The activation of defence brain circuits drives decisions to help conspecifics under threat.

Experimental evolution of yeast models of congenital disorders of glycosylation reveals that reduction, but not loss, of phosphoglucomutase activity best compensates for impaired phosphomannomutase activity.

Across 63 large US cities, street tree communities are shaped by climate, clustered by species, and made more similar between cities due to the presence of introduced species.

Active selfish genetic elements in infected cells aid virus adaptation by catalyzing the transfer of host genes to virus genomes.

The analysis of mass-spectrometry data for all possible open reading frames reveals protein evidence for evolutionarily young, unannotated proteins with distinct characters.

The wtf family of meiotic drivers has maintained the capacity to cause meiotic drive for over 100 million years.

A new bacterium isolated from an underground stream shows a novel multicellularity by self-organizing its filamentous cells like a liquid crystal and accommodating daughter cells in a sequential manner, which would be a new extant model of prokaryotic multicellularity.

A new species of multicellular bacteria broadens our understanding of prokaryotic multicellularity and provides insight into how multicellular organisms arise.

In Drosophila, genomic CRISPR/Cas9 expression necessary for CRISPR-based gene drives harbors fitness costs presumably caused by off-target effects, which can be minimized by using a high-fidelity version of Cas9.

Phylogenetic evidence suggests that the majority of HIV infections occurring in the UNAIDS Fast-track city Amsterdam continue to have an Amsterdam resident as source, indicating that the majority of HIV infections in Amsterdam could be prevented through city-level interventions.
