RNA molecules with identical nucleotide sequences can adopt different structures. Mutations can alter their properties; for example, some mutations increase the stability of a functionally relevant structure at the expense of other structur...
Individual detachment-reintegration events in homing pigeon flocks and the dominance of directional adjustment in their kinematic features [0.03%]

Individual detachment-reintegration processes offer a useful window into brief non-steady reorganization in collective flight, but whether such events can be identified objectively across flight trials remains unclear. Using high-resolution...

The effect of thermal stress on beneficial symbiosis, in the face of rapid climate change, remains poorly understood. We investigate this using the model system, Euprymna scolopes (Es), the Hawaiian bobtail squid, and its bioluminescent sym...
Distinct geometrical landscapes distinguish between modes of tristability in gene regulatory networks [0.03%]

Geometrical models have recently been used to construct landscapes for cell-fate decisions inferred directly from experimental data. However, such quantitative cell-fate data are available for only a few systems; instead, gene regulatory ne...

The slime mould Physarum polycephalum has emerged as a model system for self-organization and coordination of contractile activity at large spatial scales. This organization results from cytoplasmic flows generated by propagating contractil...

Terracettes, striking, step-like landforms that stripe steep, vegetated hillslopes, have puzzled scientists for more than a century. Competing hypotheses invoke either slow mass wasting (gravity-driven soil flow) or the relentless trampling...

Male dragonflies engage in aggressive aerial contests to establish breeding territories. Using field stereographic recordings of Trithemis aurora, we examined dragonfly behavioural objectives during these encounters. Unlike predatory pursui...

Understanding microbial communities is essential for progress in ecology, biotechnology and human health. In the last decade, constraint-based metabolic models of individual organisms have been combined to study microbial consortia. In this...

Filamentation, a shape-shifting response commonly observed under stress, has often been viewed as a by-product of cellular damage. However, it has remained unclear whether filamentation alone, independent of the canonical SOS response, conf...

Recent advances in human mobility research have revealed consistent pairwise characteristics in movement behaviour, yet existing mobility models often overlook the spatial and topological structure of mobility networks. By analysing million...
