Abstract: Abstract The presence of shell bands is common in gastropods. Both the marine snails Littorina fabalis and Lttorina saxatilis are polymorphic for this trait. Such polymorphism would be expected to be lost by the action… read more here.

Abstract: Intratumoral heterogeneity is a major obstacle for many cancer therapies. Treatment modalities which target a particular phenotype select for cells with different phenotypes. For example, chemotherapy which targets fast-dividing cells may select for a tumor… read more here.
