Age-Related Behavioral Changes Across the Adult Lifespan of a Cricket: A Longitudinal Analysis Using DeepLabCut

<title>Abstract</title> Aging in insects is characterized by progressive behavioral changes, including declines in locomotion, altered sleep, and disrupted circadian rhythms. The two-spotted cricket ( <italic>Gryllus bimaculatus</italic> ) is a useful model for behavioral senesce...

Social system and spatial behavior drive interspecific differences in foraging intensity and plant-level damage in sympatric ungulates

Foraging behavior in ungulates affects not only their own fitness but also the fitness and morphology of the plants they consume. While intraspecific variation in ungulate foraging behavior has been extensively studied, interspecific differences—particularly those associated with...

A Programmable Nanovesicle Platform for MegapascalPressure Sensing

Abstract Hydrostatic pressure (HP) is a subtle yet pervasive force that shapes chemistry and biology from the ocean floor to living cells─yet real-time HP sensing at the microscale remains elusive. Here, we report pyrene-modified polyionic complex vesicles (Pyr-PICsomes) as a cla...

Genome analysis of the glycosphingolipid-producing green alga Tetraselmis sp. NKG400013

Abstract Microalgae are gaining attention as sustainable resources for the production of valuable compounds, including biofuels, pigments, and bioactive metabolites. To support metabolic engineering and genome editing approaches aimed at enhancing these traits, high-quality genom...

“Grafting-From” Synthesis of Cellulose Acetate-graft-Poly(propylene carbonate) and Evaluation of Its Physical Properties

Poly(propylene carbonate) (PPC) is synthesized through the alternating copolymerization of propylene oxide (PO) and carbon dioxide (CO2) and has been widely studied as a sustainable polymer material. Although PPC is known for its biodegradability, biocompatibility, high optical t...

Impulse-induced liquid jets from bubbles with arbitrary contact angles

This paper investigates the relationship between the contact angle of a spherical bubble attached to a tube submerged in a container and the jet speed induced by an impulsive acceleration at its base. While it has been well established that bubble geometry strongly influences the...

Engineering a Highly meta -Selective Biphenyl Monooxygenase for the Biosynthesis of High-Value Polymer Precursors

Abstract The meta-selective C–H functionalization of aromatic substrates lacking meta-directing electron-withdrawing groups remains challenging. To engineer the regioselective enzymatic conversion of biphenyl (BP) to 3,3′-dihydroxybiphenyl (33DHBP), an industrial precursor to hig...

Natural factors, not land use type, determine topsoil mercury levels in the urbanized mosaic of the Hengduan Mountains, Qinghai-Tibet Plateau, China

Context It is widely recognized that contaminants in urban topsoil can present substantial threats to ecosystems and human health. Mercury (Hg) is a persistent pollutant arising from both anthropogenic (industrial and transport emissions) and natural (e.g. biomass burning, weathe...
