The mathematical model incorporating new parameters explains multimodal distributions in escape direction (i.e., multiple preferred escape trajectories), which are previously observed in various animal taxa.
The crystal structure of bacterial RNA polymerase bound to the transcription bubble reveals key features that support the formation of a double-strand/single-strand DNA junction at the upstream edge of the −10 element where bubble formation initiates.
Multiple trans-synaptic tracing methods reveal that there is no spatial segregation between flexor and extensor premotor interneurons in the lumbar spinal cord.

Detailed tracking of live predators attacking live schools of prey reveals the crucial interplay between predator attack strategy and prey behaviour and positioning in determining the predation risk within mobile animal groups.
Intraspecific predator interference enables a wide range of consumer species to coexist with a limited variety of resources, explaining the paradox of the plankton and species diversity patterns across ecosystems.

A flexible transcription initiation architecture and a uniform regulatory grammar buffer expression variability and the effects of genetic variants on essential genes while a rigid transcription initiation architecture and a diverse regulatory grammar ensure condition-specific responsiveness of other genes.

A combination of genetics, expression, genomic localization, and genomic nucleosome profiling demonstrates antagonism between two chromatin remodelers that reveal different mechanisms at different promoter architectures.
