A novel methodology, using diversity search AI algorithms, for exploring the space of possible behaviors of gene regulatory networks, from the perspective of generic problem-solving agents navigating their environment.

Electric signals produced by weakly electric gymnotiform fish, long seen as communication attempts, may also serve to localize conspecifics, revealing a distinct functional role.

Reinforcement learning produces long-lasting realignment of layer 1 apical dendrite tuft responses to behaviorally relevant task dimensions, both rewarded and unrewarded.

The scaling invariance of the droplet size distribution as a universal aspect of protein phase separation is reported, providing a quantitative approach to determinate the critical concentration for this process.

A hyperpolarization-activated cation channel, counteracting membrane depolarization, delimits the excitability of receptor neurons subjected to naturally prolonged stimulation to preserve the function of neighboring receptor neurons in Drosophila gustation.
