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 […]

Sphingolipid synthesis maintains nuclear membrane integrity and genome stability during cell division

Lipid synthesis must be precisely regulated to support membrane growth and organelle biogenesis during cell division, yet little is known about how this process is coordinated with other cell cycle events. Here, we show that de novo synthesis of sphingolipids during the S and G2 phases of the cell cycle is essential to increasing nuclear […]

Crushing vs. Slashing: New skull scans reveal how giant dinosaurs killed

A new analysis of the bite strength of 18 species of carnivorous dinosaurs shows that while the Tyrannasaurus rex skull was optimized for quick, strong bites like a crocodile, other giant, predatory dinosaurs that walked on two legs — including spinosaurs and allosaurs — had much weaker bites and instead specialized in slashing and ripping […]
