A single-cell map of C. elegans’s transcriptome during development finds cell lineages that start out genetically different and end up as cells of similar function and genetic profile.
Suppressing the natural age-related increase in neuronal excitation lengthens the lives of worms, and there are indications that the same may be true for mice and humans.
Transcriptional profiling of post-mortem human brains reveals commonalities in the genes over- and under-expressed in schizophrenia, bipolar disorder, autism, and major depression.
