Equivalence testing and Bayes factors are informative statistical methods for analyzing replication studies of original studies with null results, and can address the limitations of the commonly used non-significance criterion.

Bayesian estimation of the proportion of the population that would show an effect in an experiment provides a broadly applicable alternative to standard null hypothesis tests on the population mean with several advantages.

The enzyme PKMzeta is crucial for the maintenance of long-term memories, but a closely related enzyme provides a back-up should PKMzeta fail, thus explaining the controversy over why deleting the gene for PKMzeta may not appear to impair memory.

The use of preparatory activity in the smooth eye movement region of the frontal eye fields as a visual-motor gain signal allows preparation to progress without inappropriate movement.

What can authors and reviewers do to keep common statistical mistakes out of the literature?

The animacy organization in human ventral visual cortex is driven by both the presence of animal-diagnostic visual features and the psychological property of agency.

Herpes simplex ICP4 preferentially binds to and delineates the viral genome, ultimately resulting in robust viral transcription at the expense of the host.

Microbiomediversity favors further diversity in a positive feedback that is strongest in lower-diversity biomes but which plateaus as niches are increasingly filled in higher-diversity biomes.

The sickle cell trait strongly protects against not only retinopathy-positive cerebral malaria but also retinopathy-negative cerebral malaria, providing evidence that malarial parasites also contribute to retinopathy-negative cerebral malaria and are not innocent bystanders.

Although questionable research practices inflate false positive rates, they have little effect on replicability because they also increase power.
