摘要：Central emotion theories assume that during threatening and dangerous events the human face signals a prototypical, distinct, and universally recognized expression of fear which can be accurately decoded by conspecific perceivers. Due to the importance of fear expressions, an unusually large body of research has been dedicated to exploring their evolutionary origins, neurobiological mechanisms, and clinical significance. However, these studies typically utilize highly recognizable posed actor ...

摘要：Neural circuits comprise multiple interconnected regions, each with complex dynamics. The interplay between local and global activity is thought to underlie computational flexibility, yet the structure of multiregion neural activity and its origins in synaptic connectivity remain poorly understood. We investigate recurrent neural networks with multiple regions, each containing neurons with random and structured connections. Inspired by experimental evidence of communication subspaces, we use l...

摘要：Infiltrating macrophages contribute to muscle dystrophic changes in Duchenne musblood Ly6Chi inflammatory monocyte recruitment. This is accompanied by transient improvement of muscle damage, fibrosis, and regeneration. The benefit, however, is lost after the expansion of intramuscular Ly6Clo macrophages. To address the mechanisms underlying the Ly6Clo macrophage expansion, we compared mdx5cv/Nur77-/- and mdx5cv/ Ccr2-/-/Nur7-/- mice with mdx5cv and mdx5cv/Ccr2-/- mice, respectively, and found ...

摘要：Development of efficient cell factories that can compete with traditional chemical production processes is complex and generally driven by case- specific strategies, based on the product and microbial host of interest. Despite major advancements in the field of metabolic modeling in recent years, prediction of genetic modifications for increased production remains challenging. Here, we present a computational pipeline that leverages the concept of protein limitations in metabolism for predicti...

摘要：Telomerase elongates telomeres to maintain chromosome stability in most eukaryotes. Despite extensive studies across eukaryotic kingdoms, the telomerase holoenzyme in arthropods remains poorly understood. In this study, we purify the telomerase ribonucleoprotein complex from the lepidopteran insect Spodoptera frugiperda (fall army- worm) and identify a copurified 135- nucleotide telomerase RNA (TR) component. This miniature S. frugiperda TR (sfTR), the smallest TR known to date, retains a univ...

摘要：Predictive synthesis of aqueous organic solutions with desired liquid-solid phase equilibria could drive progress in industrial chemistry, cryopreservation, and beyond, but is limited by the predictive power of current solution thermodynamics models. In particular, few analytical models enable accurate liquidus and eutectic prediction based only on bulk thermodynamic properties of the pure components, requiring instead either direct measurement or costly simulation of solution properties. this...

摘要：To investigate the structure of the mycobacterial oxidative phosphorylation machinery, we prepared inverted membrane vesicles from Mycobacterium smegmatis, enriched for vesicles containing complexes of interest, and imaged the vesicles with electron cryomicroscopy. We show that this analysis allows determination of the structure of both mycobacterial ATP synthase and the supercomplex of respiratory complexes III and IV in their native membrane. The latter structure reveals that the enzyme mala...

摘要：Natural selection often acts on multiple traits simultaneously. For example, the virus HIV-1 faces pressure to evade host immunity while also preserving replicative fitness. While past work has studied selection during HIV-1 evolution, as in other examples where selection acts on multiple traits, it is challenging to quantitatively separate different contributions to fitness. This task is made more difficult because a single mutation can affect both immune escape and replication. Here, we deve...
