An improved culture method for explanted adult Drosophila organs allows the live-imaging of damage response, cell differentiation, and tracing of progenitor cell lineages through multiple rounds of division.

Fat2 signals from the trailing edge of each cell to localize WAVE activity to the leading edge of the cell behind, polarizing protrusive regions within cells and across the epithelium.

Parkinson’s disease-associated LRRK2 kinase is recruited to membranes by its Rab GTPase substrates, and LRRK2 is both retained on membranes and further activated there by cooperative interaction with the phosphorylated Rab proteins that it generates.

A novel experimental paradigm investigating how humans manage limited search capacity over many alternatives reveals close-to-optimal behaviours and identifies heuristics used to minimize computation with little impact on performance.
Behavioral, lipidomic, and genetic analyses of adult Drosophila on a chronic high-sugar regime identified that fat body activity of a phospholipid biosynthesis enzyme, Pect, regulates insulin sensitivity and hunger response.

The SPARC complex directs accurate RNAPII positioning for transcription initiation and, in some instances, ensures correct transcription directionality in Trypanosoma brucei.
