Researchers combined 2019 reconstructed marine fisheries landings from Sea Around Us with FAO inland fisheries and aquaculture data to measure how much invertebrates such as mollusks, crustaceans, sea cucumbers and jellyfish contribute to global seafood production. They standardized species names using the ASFIS taxonomic system and checked their findings across multiple years from 2014 to 2019 to confirm consistency. The analysis treated marine and inland fisheries separately due to gaps in reconstruction data for freshwater systems.
A new review synthesizes the evolving treatment landscape for metabolic dysfunction-associated steatohepatitis (MASH), the liver disease formerly called NASH, drawing on updated epidemiological data, revised diagnostic terminology, and studies on liver fibrosis assessment. It outlines existing approaches alongside emerging therapies aimed at addressing the disease's metabolic, cardiovascular and cancer-related complications.
Researchers built CW-Net, an explainable version of a black-box machine learning planner (based on the DriveIRL architecture) used to evaluate self-driving vehicle trajectories. The system was trained on two large datasets of millions of driving scenarios labeled with human-understandable concepts, allowing it to justify its trajectory choices in terms people can interpret rather than as opaque scores.
A newly compiled research review synthesizes recent findings on metabolic dysfunction-associated steatotic liver disease (MASLD) and its more severe form, MASH, tracing the field from its 1980 origins as NASH to the 2023 multisociety nomenclature update. It highlights recent multiomic and genetic studies showing that MASLD is not one uniform disease but splits into at least two distinct subtypes—one driven mainly by liver-specific factors and another tied to broader cardiometabolic dysfunction. The review also draws on global epidemiological data covering adult, pediatric and adolescent populations to frame the disease's rising burden.
Researchers modified the tethered Ribo-T ribosome system in E. coli by appending open reading frames for GFP, DFR and HiBiT directly onto the 3′ end of 16S rRNA, creating 'Ribo-TM' constructs. Gel electrophoresis and RT-PCR confirmed the fused mRNA-rRNA molecules were intact and correctly assembled inside functioning ribosomes, and growth assays with mutant ribosomal subunits helped verify that translation activity depended on a functional ribosome.
A new comparative analysis shows that pine trees planted in the Southern Hemisphere grow faster and cope with drought stress more effectively than pines in their native Northern Hemisphere ranges. Researchers attribute this to differences in growth-lifespan trade-offs and the absence of co-evolved pests and competitors that constrain growth in native habitats. The findings draw on decades of research into tree mortality, carbon storage, and invasive species dynamics across hemispheres.
A new analysis draws on atmospheric measurement records and emission datasets to explain why global methane concentrations temporarily plateaued rather than kept rising. Researchers attribute the pause primarily to increases in nitrogen oxide (NOx) emissions and a geographic shift of those emissions toward the Southern Hemisphere, which altered atmospheric chemistry governing methane's main removal pathway via hydroxyl radicals.
Researchers outline how six transition form factors govern the semileptonic weak decay of hyperons, focusing on the Lambda baryon's decay into a proton, electron and antineutrino. They show that because scalar and pseudoscalar form factors are suppressed by lepton-to-hyperon mass ratios, the electron-antineutrino channel effectively depends on just four form factors and the CKM parameter Vus, allowing a simplified branching ratio formula.
Researchers pooled data from 46 cohorts through the ReGPC consortium to run genome-wide association analyses on personality traits among participants with European-like and African-like ancestry. They applied strict quality controls—filtering low-frequency variants, poor imputation quality, and problematic samples—before analyzing how genetic variants relate to standardized Big Five personality measures.
Researchers at UC Berkeley gave 20-month-old female mice daily low-dose subcutaneous semaglutide, the active ingredient in drugs like Ozempic and Wegovy, and compared them with saline-treated and calorie-restricted counterparts. Over months of treatment, the semaglutide group showed slowed markers of aging and, in a full lifespan cohort of about 80 mice, longer survival than untreated controls.
Scientists engineered synthetic protein assemblies from the bottom up that can package and transport RNA molecules into human cells, using standard molecular cloning and transfection techniques in HEK293T cell lines. They validated the approach with a split-luciferase reporter system to confirm successful RNA delivery and functional expression inside cells.
A review of recent physics literature traces how AI tools like Melvin, Tachikoma and PyTheus have moved from proposing quantum optics setups on paper to producing configurations that experimentalists later built and confirmed in the lab. These systems use approaches ranging from genetic algorithms to diffusion models and neural network surrogates to search vast spaces of possible experimental arrangements, particularly in quantum information and photonics.
