Researchers used pseudotyped lentiviral particles to analyze how single mutations in the RSV F protein impact the effectiveness of existing neutralizing antibodies. The study highlights ongoing viral evolution under immune pressure and provides data to guide future antibody development. No infectious viruses were created during the experiments, ensuring biosafety compliance.
Researchers built a vacuum ultraviolet spectroscopy setup, using frequency-doubled laser light guided by dichroic mirrors into a chamber holding a thorium-229-doped crystal, to probe the nucleus's unusually low-energy isomeric transition. The system combined a stabilized frequency comb, referenced either to an atomic maser clock or an Yb+ ion clock, with precise beam alignment and a photomultiplier detector to record absorption signals from the crystal as the laser was scanned across the transition frequency.
Scientists synthesized thermally activated delayed fluorescence (TADF) block copolymers using atom transfer radical polymerization, first removing bromo end groups through hydrogenation and then building crosslinkable electroluminescent photoresists (ELPRs) from these polymers as macroinitiators. By adjusting the ratio of crosslinkable monomer to macroinitiator, the team controlled crosslinker density in the final light-emitting polymer material.
Researchers built Paper2Agent, a system that converts a scientific paper and its accompanying codebase into a functional MCP server accessible through an AI agent interface. It uses a multi-agent architecture built on Claude Code's agent SDK, with a central orchestrator directing specialized sub-agents through a six-step process covering repository discovery, environment setup, tutorial scanning, and execution auditing.
Researchers show that mitochondrial fission factor (MFF) controls a chain of events during ferroptosis, linking mitochondrial dysfunction, peroxisomal and mitochondrial ROS production, and release of mitochondrial DNA into the cytosol through VDAC1 oligomerization. Using CRISPR knockouts, rescue experiments and pharmacological inhibitors in HeLa cells, they mapped how loss of MFF or its downstream partners (PEX5, MFN1/2, DRP1) alters cell survival after RSL3-induced ferroptotic stress.
Researchers engineered mice with genetically depleted cortical tissue using Emx1-cre and Esco2 conditional knockout lines, then implanted human-derived brain organoids grown from induced pluripotent stem cells into the resulting cavity. The organoids were produced by aggregating dissociated hiPS cells in microwell plates and guiding them through early neural differentiation with dorsomorphin and SB-431542 before transplantation.
Researchers filtered the PostgreSQL version of the CHEMBL34 database to find pairs of compounds tested against the same protein target, assay, activity type and publication, where one molecule was a simple chemical modification of the other (such as swapping a hydrogen for fluorine or a carbon for nitrogen). This produced 191,732 parent-analogue pairs, which the team supplemented by synthesizing new analogues from 18 selected parent compounds using RDKit-driven enumeration of feasible single-atom substitutions, each capped at $400 per 10 mg.
Scientists studying Arabidopsis have uncovered how the plant hormone salicylic acid controls immune gene expression through two receptor systems, NPR1 and NPR3/NPR4. They found that salicylic acid prompts NPR1 to bind a protein called MED15A, linking it to the cell's transcription machinery to activate defense genes, while simultaneously blocking NPR3/NPR4 from partnering with NIMIN1 and repressive complexes that would otherwise silence those genes.
Researchers propose that Alzheimer's disease progresses through distinct molecular and cellular phases marked by biological thresholds, rather than a simple straight-line path from amyloid buildup to Tau pathology to neurodegeneration. At these thresholds, cells lose homeostatic balance and shift behavior, with these altered states spreading unevenly across brain tissue and eventually reaching regions critical to cognition. A key threshold identified is when amyloid triggers Tau phosphorylation, marking the transition from amyloid-driven tissue states to ones dominated by neuronal stress responses.
Researchers are increasingly using wearable devices—smartwatches, wristbands, patches and rings—to collect real-time physiological data such as heart rate, blood pressure and activity in clinical trials. Specialists say advances in sensor technology and AI could enable decentralized trials where participants are monitored remotely, with dosing personalized to individual data rather than fixed protocols. Current devices already track metrics via accelerometers, gyroscopes and photoplethysmography, with future versions potentially measuring biomarkers like glutamate and cortisol.
Wuyoh Sui, a digital-health researcher at Western University in Canada, examined how smart watches and rings are increasingly used in scientific studies of exercise, sleep and chronic disease. He points out that these commercial devices rely on opaque AI algorithms whose data handling is difficult to audit, raising ethical questions for researchers who adopt them.
Nature's science-fiction feature Futures ran a short story depicting numbered workers confined to a windowless facility, sedated with pills and coffee, weaving filaments under fluorescent light while elders recall a vanished world of trees. The piece imagines a future where natural landscapes have been erased and human labor is mechanized, monitored, and chemically controlled.
