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.
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.
Action-selection under response-conflict is buttressed by an inhibitory control signal from the basal ganglia that non-selectively suppresses motor excitability.
Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.
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.
New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.
