Cover: Caenorhabditis elegans larvae crawling amongst developing early embryos. The spinning-disc confocal microscopy image shows fluorescent fusions of the DNA-binding protein BAF (yellow, mCherry-tagged BAF in larvae) and the inner nuclear membrane protein LEM-2 (blue, mNeonGreen-tagged LEM-2 in embryos) expressed from the endogenous loci. See article by S. R. Barger et al. (jcs261385).

RESEARCH HIGHLIGHTS
CELL SCIENTISTS TO WATCH
REVIEWS
30 years of nanobodies – an ongoing success story of small binders in biological research
Summary: In this Review we briefly summarize the basis for the development of nanobodies and provide an overview of the multiple applications of these versatile binders in biological research.
Cellular and molecular functions of SETD2 in the central nervous system
Summary: SETD2 catalyses trimethylation of lysine 36 on histone H3. Here, we review the roles of SETD2 in mammals, with a focus on the central nervous system, and summarise the consequences of pathogenic SETD2 variants in humans.
SHORT REPORT
Characterization of Pik1 function in fission yeast reveals its conserved role in lipid synthesis and not cytokinesis
Summary: Fission yeast Pik1 localizes exclusively to the trans-Golgi independently of Ncs1, where it contributes to PI4P but not PI(4,5)P2 synthesis. Pik1 does not affect cytokinesis.
RESEARCH ARTICLES
Nuclear envelope assembly relies on CHMP-7 in the absence of BAF–LEM-mediated hole closure
Highlighted Article: In C. elegans, nuclear closure around spindle microtubules requires BAF-1 binding to LEM-domain proteins and reveals redundant and unique functions for EMR-1, LEM-2 and CHMP-7 in nuclear maintenance.
Palmitate-induced insulin resistance causes actin filament stiffness and GLUT4 mis-sorting without altered Akt signalling
Highlighted Article: Saturated fats elicit muscle cell-autonomous dysregulation of the basal-state machinery required for the GLUT4 translocation that ‘primes’ skeletal muscle cells for insulin resistance.
Separation-of-function MCPH-associated mutations in CPAP affect centriole number and length
Summary: Defects in centrosome organization (centriole number and length) are imparted by MCPH-associated mutations in the CPAP G-box domain, which impacts spindle organization and cell survival.
Centrosome amplification promotes cell invasion via cell–cell contact disruption and Rap-1 activation
Summary: Centrosome amplification is sufficient, without additional pro-oncogenic alterations, to drive early tumorigenic change in a normal breast epithelial background.
The SUN-like protein TgSLP1 is essential for nuclear division in the apicomplexan parasite Toxoplasma gondii
Summary: Identification of a SUN-like protein in the apicomplexan parasite Toxoplasma gondii that is essential for replication.

Origin and evolution of mitochondrial inner membrane composition

In this Review, Kailash Venkatraman and colleagues provide an examination of the morphological similarities between prokaryotic intracytoplasmic membranes and mitochondrial inner membranes, and whether cristae evolution has driven specialisation of the mitochondrial lipidome.
Resolution in super-resolution microscopy
Super-resolution microscopy (SRM) has emerged as a powerful tool for biological discovery. In this Perspective, Kirti Prakash and colleagues compile expert opinions on crucial, yet often overlooked, aspects of SRM that are essential for maximising its benefits and advancing the field.
