Dopamine, a reward signal in the brain, can retroactively convert hippocampal synaptic depression into potentiation, suggesting an elegant biological solution to the distal reward problem.
anTraX is an algorithm and software package that facilitates automated analyses of insect social behavior in species and experimental settings that are not accessible with currently existing technology.
By properly accounting for gene copy number and cell-cycle effects, single cell snapshots of nascent and mature mRNA can be used to unveil the stochastic kinetics of gene activity.
The time it takes to secrete a protein is dominated by diffusion of positively charged arginines through the channel across the membrane, but lysines avoid this problem as they are neutralised before transport.

Emergent property inference, a novel machine learning methodology, learns distributions of neural circuit model parameters that produce computational properties and provides novel scientific insight through the quantification of the rich parametric structure it captures.
The proposed method deciphers which low-level patterns (such as spikes) control high-level features (behavior) in relative small biological datasets, taking into account the statistical dependencies between such patterns.
