Alternative Policy Designs to Help Farmers Select Profitable Conservation Practices

Agribusiness, EarlyView.
ABSTRACT Voluntary private carbon initiatives (VPCIs) promote the implementation of agricultural conservation practices that mitigate emissions of greenhouse gases (GHGs) via financial incentives to participating farmers. Simultaneously, an array of public policies supports the adoption of conservation practices through technical and financial ...

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Correlations Between Osteocyte Lacuno‐Canalicular Network and Material Characteristics in Healthy and Mechanically Stimulated Murine Tibiae

Advanced NanoBiomed Research, EarlyView.
This article reveals how calcium content, mineral nanostructure, and lacuno‐canalicular network (LCN) organization interact to shape bone heterogeneity in mouse tibiae. Advanced multimodal imaging uncovers that mechanical loading promotes mature mineral structures even in low‐calcium regions, highlighting LCN‐driven mineralization and offering new ...

Inferring the CO2 Abundance in Comet 45P/Honda-Mrkos-Pajdušáková from [O i] Observations: Implications for the Source of Icy Grains in Cometary Comae

The Planetary Science Journal
The study of cometary composition is important for understanding our solar system's early evolutionary processes. Carbon dioxide (CO _2 ) is a common hypervolatile in comets that can drive activity but is more difficult to study than other hypervolatiles

Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

Cancer Nexus, EarlyView.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

The Long-Term Dynamical Behavior of Short-Period Comets [PDF]

Icarus, 1994
We have developed and carefully tested a new computer code to follow the long-term dynamical evolution of a swarm of test particles in the solar system. This new integrator is approximately an order of magnitude faster than previously existing codes. The technique efficiently and accurately handles close approaches between test particles and planets ...

Consensus findings of an International Workshops on Genotoxicity Testing workshop on using transcriptomic biomarkers to predict genotoxicity

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Gene expression biomarkers have the potential to identify genotoxic and non‐genotoxic carcinogens, providing opportunities for integrated testing and reducing animal use. In August 2022, an International Workshops on Genotoxicity Testing (IWGT) workshop was held to critically review current methods to identify genotoxicants using ...

Multiple Outbursts of Halley-type Comet 12P/Pons–Brooks

The Astronomical Journal
We present optical observations of the Halley-type comet 12P/Pons–Brooks (12P) on its approach to perihelion. The comet was active even in the first observations at ∼8 au.

A Systematic Mapping Review of Core Outcome Reporting in Surgical Research for Oesophageal Cancer

Journal of Surgical Oncology, EarlyView.
ABSTRACT Oesophageal carcinoma is a rising global health burden, with surgical resection and perioperative chemotherapy forming the cornerstone of curative treatment. However, uncertainty persists regarding the optimal surgical approach, partly due to heterogeneity in outcome reporting, which hinders data synthesis and evidence‐based decision‐making ...

On the Early Thermal Processing of Planetesimals during and after the Giant Planet Instability

The Planetary Science Journal
Born as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets’ dynamical instability in the early stages of our solar system’s history.
