Fluorescence lifetime imaging microscopy, paired with fluorescent, voltage-sensitive dyes, provides a method for measuring and quantifying membrane potentials of living cells.

Several neuronal subtypes found in the early zebrafish olfactory placode are not derived from the neural crest, as previously thought, but from the preplacodal ectoderm.

Ptch1/2 can lower the sensitivity of Smo to activation by Shh via the secretion of a sterol precursor.

The planarian mex3-1 gene is required for non-stem cell fates and suppresses a stem cell fate in differentiating cells.

Perturbations in the extracellular environment drive transitions from a highly stable memory state to an alternative phenotype in microorganisms.

The transcription and splicing factor T-box3 is present in primary cilia, regulates multiple aspects of limb development, and interacts with members of the protein complex required for the stability and processing of the Gli3 transcription factor.

Pre-existing enhancers interpret T cell signaling strength in an analogue manner to direct quantitative changes in gene expression within the context of an overall digital response.

Peptide immunotherapy in mice depends upon sustained expression of co-inhibitory protein PD-1 in T cells.
