In this episode we hear about how flatworms regenerate, the evolution of photosynthesis, social interactions between mice, the properties of undead cells, and how steroids and genes interact.
Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.
Regional differences in activator and inhibitor signals alter hair cycle pace across mouse skin and produce unique fur renewal 'landscapes', with fastest renewal on the ventrum and slowest renewal on the ear pinnae.
Asymmetric cell division is linked to cell-specific transcription by handoff of a key developmental regulator from the cytokinetic machinery to the adjacent cell pole where it oligomerizes to become stabilized and activated.
Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.
High-resolution live imaging reveals how and when the mouse heart first starts to beat during development and how the onset of beating impacts on heart muscle cell maturation and heart formation.
A continuum of genome relationships is discovered through comparative genomics of 627 sequenced mycobacteriophages isolated and characterized in an integrated research/education initiative.
Thousands of small Open Reading Frames are translated, and form two distinct classes based on their translational efficiency and bioinformatic indicators.
