The ability to follow single objects in 3D in a living organism with high spatiotemporal resolution opens new possibilities for quantitative biophysical studies of complex systems in their physiological context.

ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.

The Toxoplasma parasite requires an enzyme called ASP5 to cleave proteins for export into host cells.

Genetic and cell biological analyses reveal a new role of Drp1 in postsynaptic endocytosis during brain development beyond mitochondrial division GTPase.

Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.

Mechanically stimulating mitochondria causes them to divide via the recruitment of the mitochondrial fission machinery to the mechanically strained site, showing that intracellular organelles can be mechanoresponsive.

Mitochondria reach stable positions in dendrites during a critical developmental period of high motility.

Analysis of Chlamydomonas, planaria and mice reveals a novel and unanticipated role for a peptide amidating enzyme in primary and motile ciliary assembly through effects on post-Golgi trafficking.

Multivesicular bodies deliver long-range retrograde nerve growth factor (NGF) signals and serve as essential signaling and sorting platforms in the cell soma, and multivesicular body (MVB) cargoes dictate their vesicular fate.

EphB4 maintains critical functional properties of the adult cardiac vasculature, namely mechanical resistance and fatty acid transport capability, and thereby prevents dilated cardiomyopathy-like defects.
