The Unkempt RNA-binding protein reveals a local translation program in centriole overduplication

Excess centrosomes cause defects in mitosis, cell-signaling, and cell migration, and therefore their assembly is tightly regulated. The divergent Polo kinase, PLK4, controls centriole duplication at the heart of centrosome assembly, and elevated PLK4 levels promote centrosome amplification (CA), a founding event of tumorigenesis. Here, we investigate the transcriptional consequences of elevated PLK4 and find […]

Additive Manufacturing of Monolithic Gyroidal Solid Oxide Cells

In a transformative leap that challenges longstanding constraints in energy conversion technology, researchers have unveiled a groundbreaking design paradigm for solid oxide cells (SOCs) that dramatically enhances their efficiency, durability, and structural integration. Traditional SOCs, fundamental devices capable of interconverting chemical energy and electricity at high temperatures, have been largely limited by planar, two-dimensional (2D) […]

Archaeal Ribosome Shows Unique Active Site, Hibernation Factor

In the intricate machinery of life, ribosomes stand as the quintessential molecular factories responsible for translating genetic information into functional proteins. These macromolecular complexes orchestrate the decoding of messenger RNA (mRNA) into polypeptide chains, a process fundamental to all cellular organisms. Despite the long evolutionary journey and the structural variations observed across different domains of […]

A biotin-HaloTag ligand enables efficient affinity capture of protein variants from live cells

HaloTag technology represents a versatile tool for studying proteins. Fluorescent HaloTag ligands employed in sequential labeling led to the discovery of distinct protein variants for histones, cohesins, and MCM complexes. However, an efficient biochemical approach to separate these distinct protein variants to study their biological functions is missing. Principally, being a gap in technology, the […]

Flowering Plant Gene Regulation: Recruitment, Rewiring, Conservation

In the sprawling and intricately wired world of plant genetics, transcription factors (TFs) have emerged as central conductors orchestrating gene expression. These proteins bind to discrete regions of DNA, known as transcription factor binding sites (TFBSs), modulating when and where genes become active. This process underpins every aspect of plant life, from cellular identity and […]

Nonmuscle myosin II regulates presynaptic actin and neuronal mechanobiology in Drosophila

Neuromuscular junctions (NMJs) are evolutionarily ancient, specialized contacts between neurons and muscles. They experience lifelong strain, yet the mechanism preserving their integrity under mechanical load remains unclear. Here, we identify a novel actomyosin structure at Drosophila larval NMJs, consisting of a long-lived, low-turnover presynaptic actin core that colocalizes with nonmuscle myosin II (NMII) and becomes […]

Metabolic Syndrome Links BMI and Depression Trajectories

In a groundbreaking cohort study emerging from China, researchers have explored the complex interplay between body mass index (BMI), depressive symptoms, and metabolic syndrome in adults over the age of 45. This investigation not only illuminates the intricate cross-sectional and longitudinal associations between these health parameters but also delves into the mediating influence of metabolic […]

Optogenetic and chemical genetic tools for rapid repositioning of vimentin intermediate filaments

Intermediate filaments (IFs) are a key component of the cytoskeleton, essential for regulating cell mechanics, maintaining nuclear integrity, organelle positioning, and modulating cell signaling. Current insights into IF function primarily come from studies using long-term perturbations, such as protein depletion or mutation. Here, we present tools that allow rapid manipulation of vimentin IFs in the […]

Key Amino Acid Changes Attenuate Yellow Fever Vaccine

In a groundbreaking study published in Nature Microbiology, researchers have uncovered the molecular underpinnings that enable the yellow fever 17D vaccine strain to be both highly effective and unusually safe. Through meticulous molecular analyses, Zhang, Chavez, Winkler, and their colleagues have pinpointed specific amino acid substitutions in just two viral proteins that are responsible for […]

Scientists recreate life’s first step: Linking amino acids to RNA

Chemists at UCL have shown how two of biology’s most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of life four billion years ago. Amino acids are the building blocks of proteins, the “workhorses” of life essential to nearly every living process. But proteins cannot replicate or […]
