Today's edition
Picked for broad interest, a real step forward and honest claims, with no field allowed to take over.
In-orbit operation of a programmable quantum photonic processor
Here, we report a programmable quantum photonic platform operating on a nanosatellite, processing two photons in a six-mode universal integrated circuit.
PreprintClaims a big stepReal-world useRecursive self-improvement of AI research agents
Together, these results show that an AI research agent can improve its own research efficiency through recursive self-improvement, and that these gains transfer to tasks and domains the loop never encountered.
PreprintClaims a big stepRising water is an underappreciated driver of forest mortality
Our findings identify rising waters as a widespread, underappreciated driver of forest die-off that can extend far inland, underscoring the need to reassess the impacts of climate change on the functioning, demography, and carbon-methane budgets amongst the world's most carbon-rich forests as seas rise and hydroclimate shifts globally.
PreprintReal-world useGenerative Neuromorphic Programming of Mammalian Cells
Here we establish generative programming of mammalian cells through a neuromorphic framework that compiles desired behavior into DNA.
PreprintClaims a big stepValuing five centuries of unpaid breastfeeding in England
We impute upper and lower bounds for the value of unpaid breastfeeding over five centuries in England to better understand its economic role over the course of economic development.
Peer-reviewed journalBroad interestExo-LAMP: A Rapid Extraction-Free Isothermal Assay for Exosomal mRNA Detection
Here, we report Exo-LAMP, an extraction-free isothermal assay for detecting placental exosomal KISS1 mRNA, representing the first isothermal approach for exosomal mRNA detection.
PreprintClaims a big stepReal-world useAutonomous Quantum Transport Measurements of 2D Semiconductors by an AI Agent
Herein, we introduce an AI-driven workflow in which an AI agent performs multi-step, multi-day quantum transport measurements end-to-end.
PreprintBistability of compartmentalized autocatalytic systems at the dawn of hereditary variation
Here we show that two mutually interacting autocatalytic networks can form alternative stable chemical states, maintained by weak cross-catalysis and switched by environmental change when enclosed in reproducing compartments.
Peer-reviewed journalMultimodal Visual Sensing of Temperature and Pressure: From Spectroscopic Readout to Multiple Linear Regression-Enhanced RGB Analysis
This work presents the first application of MLR-assisted RGB analysis for quantitative luminescence pressure sensing.
PreprintClaims a big stepDense Packing of Tetrahedra in Cylinders
Combining numerical simulations with exact analytical theory, we classify the densest configurations into two continuous, mathematically tractable families: chiral Tetra Helices and achiral Dimer Chains.
PreprintClaims a big stepMultidirectional Colossal Polarization in a Centrosymmetric Crystal via Long-Range Ion Displacement
Herein, we demonstrate that colossal polarization occurs by long-range ion displacement even in the nonpolar proton conductor Na2MnN(CN)4·3.25H2O (1·H2O).
Peer-reviewed journalClaims a big stepDr-LiSA: Direct Radar-Lidar Scan Alignment for Localization
This paper introduces Dr-LiSA, a first-of-its-kind direct method for localizing 2D spinning radar intensity measurements in against 3D lidar maps.
PreprintClaims a big stepReal-world useSimulation and Analysis of Solute Transport in Multi-Lymphangion Lymphatic Vessels
Overall, the proposed PBS framework provides a first quantitative basis for solute transport modeling in the LS and several concrete application scenarios for MC in this underexplored domain.
PreprintLearned Human Aortic Morphodynamics: A Dynamical-Systems Model of Post-EVAR Sac Remodeling
Recovering the equations that govern remodeling, rather than tracking its instantaneous state, therefore provides a foundation for clinical models built from the sparse records that routine imaging surveillance actually produces.
PreprintReal-world useGenerating protein hydrogels with customizable stress relaxation behavior via deep learning-driven entanglement design
Here, we introduce TangleDiff, a deep learning framework for the de novo design of homodimeric entangled proteins with programmable features.
Peer-reviewed journalReal-world useBeyond Natural Language: An Agent-Native Language for Autonomous Science
We introduce Lara, a machine-checkable language and protocol for checking and revising support for research claims.
PreprintClaims a big stepRachel: A general-purpose language model directs and revises retrosynthetic routes
Within Rachel, a general-purpose LLM coordinated successive chemical choices and revised its strategy as earlier decisions reshaped the remaining problems.
PreprintData center cooling choices shift water impacts across the grid: An integrated water-energy model for sustainable data center development
Air-cooled data centers halve total water consumption relative to evaporative cooling, but increase electricity demand and raise indirect water consumption by one-third, shifting the water footprint from the facility to generators.
PreprintReal-world useRelegation, promotion and the components of scoring in water polo
Fitted to a new dataset of 940 matches, the model identifies the directly relegated club from the ninth round, before the league table does, predicts the play-out field better than the table, and shows the play-out itself to be close to a coin toss.
PreprintFirst Observation of a Polar Coronal Hole-like Fast Solar Wind Stream in the Sub-Alfv\'enic Solar Corona: an Analysis of Turbulence Properties
At heliocentric distances of approximately 10 solar radii, with speed mostly above 400 km/s, this interval is a first example of "polar coronal hole-like (PCH-l) fast" solar wind observed in the sub-Alfv\'enic solar corona.
