This study shows that tumor cells adapt to changing environments through phenotypic switching, with optimal survival achieved by blocking mesenchymal to epithelial transition.

This paper shows that cheaters can promote cooperation by enabling group survival in a multi-level selection model, challenging the classical view that cheaters destabilize cooperation.

This study develops a mathematical model to show that prokaryotes evolve antivirus defense strategies based on environmental virus prevalence, with adaptive immunity optimal in stable environments and HGT dominant in fluctuating ones.

This study uses a computational simulator to show how globular protein folds can evolve from random sequences, finding that stable folds emerge with 3-8 amino acid replacements per site.
