In this episode, we hear about colour vision in bats, frog vocal systems, ageing, problematic cell lines and how larger neurons could lead to a higher IQ.
The nerve growth-repellent activity that generates spinal nerve repeat-patterning in birds and mammals is identified at the molecular level, and a similar system is revealed in adult brain grey matter.
Genetic analyses illustrate the novel requirement of Ftz-f1 and Sim in adult Drosophila ovaries for regulating follicle cell differentiation and ovulation that is likely conserved in mammals.
A subcortical white matter connection from the pulvinar to the amygdala predicts how well we recognise fearful faces and the strength of feed-forward neural connectivity.
MgADP binding to the high-affinity 'consensus' ATPase active site of SUR1 and remodeling of the L0-loop (lasso region) overrides tonic ATP inhibition of KATP channels.
A multipartite virus functionally spreads its distinct genome segments in distinct individual cells of the host plant, and complementation of the viral genes across cells allows a pluricellular infection cycle.
