In this episode we hear about biofilms in bacteria, drug production, gender bias in peer review, nematode worms and how synchronising brain waves can boost memory.
In this episode we hear about controlling sperm by optogenetics, hibernation, body clocks, enzyme structure, and a way to overcome stress-induced infertility.
Astrocyte microdomain calcium transients are mediated by TrpML, stimulated by ROS and tyramine, and mediate astrocyte–tracheal interactions in CNS gas exchange.
Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.
Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.
Low-frequency correlations among neurons in monkey visual area V4 impair the animal's ability to perform an attention-demanding task, suggesting a causal role of these fluctuations in perception.
Action-selection under response-conflict is buttressed by an inhibitory control signal from the basal ganglia that non-selectively suppresses motor excitability.
A mouse virtual reality system is presented which allows normal spatial behavior and place, grid and head-direction cell firing patterns in 2-D arenas, and is compatible with electrophysiology and multi-photon imaging.
