A Generic Approach to Creating a National Soil Security Strategy

open access: yesSustainable Development, EarlyView.
ABSTRACT Soil is a living and non‐renewable resource that underpins our very existence. It produces our food, filters our water, stores vast amounts of carbon, cycles essential nutrients, and sustains the rich tapestry of biodiversity on which our planet depends.

A Modified Hierarchical Vision Transformer for Soil Moisture Retrieval From CYGNSS Data

open access: yesWater Resources Research
This research introduces a new deep learning (DL) framework, multi‐head self‐attention‐aided vision Transformer (MSA‐ViT), for soil moisture (SM) retrieval using Cyclone Global Navigation Satellite System (CYGNSS) data. We first assess the sensitivity of

SMAP and CalCOFI Observe Freshening during the 2014–2016 Northeast Pacific Warm Anomaly

open access: yesRemote Sensing, 2018
Data from NASA’s Soil Moisture Active Passive Mission (SMAP) and from the California Cooperative Oceanic Fisheries Investigations (CalCOFI) were used to examine the freshening that occurred during 2015⁻2016 in the Southern California Current ...

Discovery of structural and functional transition sites for membrane-penetrating activity of sheep myeloid antimicrobial peptide-18

open access: yesScientific Reports, 2023
Cathelicidin antimicrobial peptides have an extended and/or unstructured conformation in aqueous solutions but fold into ordered conformations, such as the α-helical structure, when interacting with cellular membranes. These structural transitions can be

Presynaptic actin nanostructures: A reproducibility case study

open access: yesJournal of Microscopy, EarlyView.
Abstract In an effort to assess the reproducibility of bioimage analyses in current publications, we took part in a Global BioImage Analysts’ Society (GloBIAS) initiative to try and reproduce results from published articles. We attempted to reproduce core findings from Bingham et al.

Biocrust restoration in novel climates: assisted migration, habitat amelioration, and varied community composition as climate‐smart techniques

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Successful restoration of terrestrial drylands depends on stable, fertile soils that retain water. These functions are provided by biological soil crusts (biocrust), suggesting their reestablishment is a critical step in dryland restoration.

Floods From Space: How Remote Sensing, AI, and Cloud Platforms Are Reshaping Disaster Risk Reduction

open access: yesJournal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Flooding remains one of the most damaging climate‐related hazards globally, yet flood remote sensing has historically developed largely along sensor‐specific pathways. This review addresses the need for a systematic and decision‐oriented synthesis of how space‐borne remote sensing has evolved toward integrated flood monitoring and disaster ...

Validation of SMAP Soil Moisture at Terrestrial National Ecological Observatory Network (NEON) Sites Show Potential for Soil Moisture Retrieval in Forested Areas

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Soil moisture influences forest health, fire occurrence and extent, and insect and pathogen impacts, creating a need for regular, globally extensive soil moisture measurements that can only be achieved by satellite-based sensors, such as NASA's ...
