Covariance decomposition distinguishes coalescent and substitution noise in species-tree estimation
This research indicates that pairwise distance estimates in species-tree methods can be decomposed into coalescent and substitution noise components, and that the dominant source of variance depends on mutation rate and species-tree height.

Longer-lived C. elegans show expanded decrepitude, not slower ageing
This research indicates that reduced beta values in Gompertz mortality curves reflect expanded decrepitude in longer-lived Caenorhabditis elegans, while reduced alpha values better match expanded healthspan and slower biological ageing.

Computational cell biology needs principles for viability
This research indicates that computational cell biology needs a theory of viability that addresses the life-death boundary, and that geometric structures in a model's state space may help organize cell fate.

Tick bite and DSCATT are linked to distinct circulating miRNA changes
This research indicates that tick bite and Debilitating Symptom Complexes Attributed to Ticks (DSCATT) are associated with changes in circulating host microRNAs and with a five-microRNA signature that classified acute tick bite with 86% accuracy.

Border cell migration is shaped by tangential contact forces and tissue geometry
This research indicates that a phase-field model can capture how border cell cluster migration in the Drosophila egg chamber is guided by contact-mediated propulsion, tissue geometry, and chemical cues.
