Self-loops in Evolutionary Graph Theory: Friends or Foes?

The paper examines the impact of self-loops on evolutionary dynamics in structured populations, showing they are beneficial at low mutation rates but detrimental at intermediate and high rates.

Bacterial c-di-GMP plays a key role in the evolution of host-association

This study shows that c-di-GMP upregulation enables bacteria to adapt to host-association across diverse species.

This paper models how phenotypic heterogeneity in cancer cells affects treatment outcomes and relapse, showing that growth rate-dependent therapies delay relapse but may create resistant subpopulations.

Why is cyclic dominance so rare?

The paper investigates why cyclic dominance is rare in nature by showing that it is more likely to emerge when new types are unrelated to existing ones rather than similar.
