There is a strand-based evolutionary mechanism for the diversification of outer membrane proteins, which has implications for how repeat proteins are created and for how outer membrane proteins fold.

Cryo-EM structures of 70S•RelA ribosome complexes reveal how cognate deacyl-tRNA activates RelA.

Serially remembered items are successively reactivated during memory maintenance in the human brain, and replay profiles, temporally compressed and reverse in order, are associated with recency effect in behavioral performance.

The combination of short-term and long-term plasticity enables hippocampus to learn goal-directed paths through replay in a reversed order.

What will happen where and when could be predicted by the sequential reactivation of place cells that occurs while an animal pauses, suggesting that the replay is linked to mental time travel.

Two distinct subpopulations of CA1 neurons that increased or decreased their firing rate during delay were identified, suggesting that they have distinct roles in the valuation process in the hippocampus.

fMRI evidence for off-task replay predicts subsequent replanning behavior in humans, suggesting that learning from simulated experience during replay helps update past policies in reinforcement learning.

Despite differing by only one amino acid in the C-terminal tail, copy 1 of yeast histone 2A has a repair-specific role not shared by copy 2.

An experimentally supported model of grid cells naturally enables them to participate in firing sequences that encode rapid trajectories in space.

An RNA-mediated mechanism that stabilizes association of the Suv39h enzymes at mouse heterochromatin is defined.
