Mechanism by which exercise strengthens bones and immunity
Scientists have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study also shows that movement-induced stimulation is required for the maintenance of this niche, as well a.....»»
Researchers identify peptides for pollen tube growth in rice
Double fertilization is a complex mechanism in flowering plants, wherein two sperm cells fuse with the embryo sac. To achieve this, pollens released from anthers must interact with the plant's stigma, hydrate, and germinate into pollen tubes. Thus, p.....»»
Scientists studying fluid dynamics explore mechanism at work in interfacial tension
Scientists have conducted a study of the interface between two liquids, focusing on a force called interfacial tension. Their numerical simulation helped them better understand the mechanism at work in interfacial tension. This work contributes to th.....»»
Glucagon receptor structures uncover new arrestin interaction mechanism
G protein-coupled receptors (GPCRs) are essential for cell signal transduction and constitute the largest drug target protein family. Upon agonist stimulation, these receptors activate multiple downstream transducers, including G proteins and arresti.....»»
Evolutionary forces shape the human skeleton
Genetic kinship analyses of human bones reach their limits if the DNA is poorly preserved or if destructive sampling is not possible. New research shows that in such cases, comparisons of the structure and shape of certain parts of the skeleton may a.....»»
Novel mechanism for oxygen evolution reaction on dual-atom catalysts increases reaction activity
Atomically precise cluster catalysts bridge the gap between homogeneous and heterogeneous catalysis, facilitating comprehensive elucidation of structure-activity relationships in catalytic processes. However, the synergistic effects between non-singl.....»»

New insights into the evolution of the plague pathogen
The origins of the plague go back to the Neolithic Age, with the oldest findings of the causative pathogen Yersinia pestis coming from human bones around 5,000 years old. In the history of the plague, the late antique Justinianic plague from the sixt.....»»
Dinosaurs and the evolution of breathing through bones
Dinosaurs' hyper-efficient breathing system also evolved in two other lineages. Enlarge / It takes careful study and the right kind of bones to determine how something like this breathed. (credit: Tito Aureliano et. al.).....»»
