A new model describes how adaptive molecular evolution shapes phylogenetic trees and can be used to estimate the fitness effects of mutations from phylogenies.

Psychophysical measurements using time pressure indicate that when attention is willfully deployed, a congruent scaccade is automatically planned, but the coupling is weak and can be rapidly broken.

Quantitative analysis of cell dynamics over a range of timescales reveals that core PCP is not required to organize large-scale tissue flows but does affect short timescale mechanics.
Many published findings about population history that rely on inference of admixture graph models fitted to f-statistics are not robust since the method is generally inappropriate for extracting new information about population history.
fMRI and high-density ECoG recordings reveal a hierarchical gradient along the auditory pathway for auditory sequence processing in the marmoset brain.
Improved 3D and 4D imaging of neurovascular processes across scales reveals new insights into eye disease mouse models and shows retinal vessels are significantly distorted using standard flat-mount confocal imaging.

A distinct subpopulation of neurons in the rat orbitofrontal cortex encodes reward history at the time of choice, providing a potential neural substrate by which reward history may influence decisions.
A principle from which the neuronal dynamics and synaptic plasticity in arbitrary network architectures can be inferred, so that output errors are online minimized while simultaneously processing sensory input streams.
