Human-based electromechanical simulations reveal electrocardiogram biomarkers are better indicators of pro-arrhythmic substrate after myocardial infarction than ejection fraction.

Diversification of a conserved cholesterol binder drives functional replacement of cholesterol with symbiont-produced sterols in corals living in nutrient-poor environments.

Eutherian CD4 evolved counterbalancing motifs in the extracellular, transmembrane, and intracellular domains that regulate CD4⁺ T cell responses to peptide antigens presented by class II MHC (pMHCII).

The T cell repertoire can display immunodominance to an epitope as a result of optimal positive selection in the thymus by one self-peptide/MHC ligand.

The ultimate driver for the substantial between-species difference in the success of transposable elements, the widely distributed genetic parasite, may lie in the overall chromatin environment.

Judgments of how much time elapsed between two events in a story are predicted by changes in fMRI activity patterns.
