摘要:Magnetotactic bacteria have evolved the remarkable capacity to biomineralize chains of magnetite [Fe(II)Fe(III)2O4] nanoparticles that align along the geomagnetic field and optimize their navigation in the environment. Mechanisms enabling magnetite formation require the complex action of numerous proteins for iron acquisition, sequestration in dedicated magnetosome organelles, and precipitation into magnetite. The MamP protein contains c- type cytochromes called magnetochrome domains that are ...

摘要:Circadian clocks respond to temperature changes over the calendar year, allowing organisms to adjust their daily biological rhythms to optimize health and fitness. In Drosophila, seasonal adaptations are regulated by temperature- sensitive alternative splicing (AS) of period (per) and timeless (tim) genes that encode key transcriptional repressors of clock gene expression. Although Clock (Clk) gene encodes the critical activator of circadian gene expression, AS of its transcripts and its poten...

摘要:Encouraging consumption of plant- based food products can help mitigate the impact of dietary choices on climate change. Research suggests that modifying environments in which people make purchasing decisions has the potential to achieve behavioral changes toward sustainable consumption. We examine the impact of two behavioral interventions, carbon footprint labeling, and product categorization, to promote sustainable food selection in an online grocery shopping environment. Online grocery sho...

摘要:Phase transition between ordered phases has garnered attention from the viewpoint of materials science as well as statistical physics. One interesting example is martensitic transformation and the resulting formation of twin structures, in which atoms or molecules that form one crystalline phase move in a concerted and diffusionless manner toward another crystalline phase. Recently martensitic transformation has been observed experimentally also in various soft materials. However, the complex ...

摘要:Increasing food production and ensuring drinking water safety have always been a focus of attention, especially for people in underdeveloped regions of the world. Traditional excessive fertilizer applications have increased crop yield but also caused groundwater nitrate pollution. Agricultural irrigating water is an important reservoir for nitrogen (N) (e.g., nitrate) accumulation after fertilization. Ammonium (NH4+-N) is a more readily absorbed N form by rice than nitrate (NO3--N). In this st...

摘要:The high-temperature superconducting cuprates host unidirectional spin- and charge- density-wave orders that can intertwine with superconductivity in nontrivial ways. While the charge components of these stripes have now been observed in nearly all cuprate families, their detailed evolution with doping varies across different materials and at high and low temperatures. We address this problem using nonperturbative determinant quantum Monte Carlo calculations for the three-band Hubbard model. U...

摘要:Unlike traditional approaches to Greco- Roman medicine, which are strongly based on textual evidence, we addressed some problems, currently debated by historians, through a technique borrowed from the biological sciences: We reenacted an ancient anatomical dissection of the abdominal wall, the peritoneal cavity, and its organs (as described by Galen during the 2nd century CE, in his major treatise Anatomical Proceedings). Our aim was to clarify incongruencies about the text itself-considering ...

摘要:Mobula rays have evolved leaf-shaped filter structures to separate food particles from seawater, which function similarly to industrial cross-flow filters. Unlike cross-flow filtration, where permeability and selectivity are rationally designed following trade-off analyses, the driving forces underlying the evolution of mobula filter geometry have remained elusive. To bridge the principles of cross-flow and mobula filtration, we establish a universal framework for the permeability-selectivity ...

摘要:Cortical condensates, transient punctate-like structures rich in actin and the actin nucleation pathway member Neural Wiskott-Aldrich syndrome protein (N-WASP), form during activation of the actin cortex in the Caenorhabditis elegans oocyte. Their emergence and spontaneous dissolution is linked to a phase separation process driven by chemical kinetics. However, the mechanisms that drive the onset of cortical condensate formation near membranes remain unexplored. Here, using a reconstituted pha...
