Impact of Sugarcane Management Practices and Time Periods on Soil Organic Carbon and δ13C Signature After Paddy Rice Conversion

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Multiproxy Chronologies of the Hurd Rock Glacier (Livingston Island, South Shetland Islands, Maritime Antarctica): Between the Late‐Stage Stabilization and Flow Deceleration

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.

Bifunctional Electrocatalysts in Rechargeable Lithium‐Gas Batteries: Material Evolution and Mechanistic Insights from Metal‐Free Carbons to Carbon‐Supported Single‐Atom Sites

open access: yesSmall, EarlyView.
This review charts the material evolution of bifunctional electrocatalysts for rechargeable lithium‐gas batteries. It highlights the journey from heteroatom‐doped, metal‐free carbon architectures to precision‐engineered carbon‐supported single‐atom sites. The discussion focuses on mechanistic insights into how these catalysts govern reversible O2, CO2,

Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

The Swanscombe fossil at 90: revisiting its phylogeny, taxonomy, and place in human origins Le fossile de Swanscombe, 90 ans après : retour sur sa place phylogénique, taxonomique et dans les origines de l'humanité

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The year 2025 marked the ninetieth since a fossil hominin occipital bone was discovered in Swanscombe, southeast England. In subsequent years, its parietal bones were found, producing what remains the oldest partial cranium from Britain today. In the earliest analyses, it was interpreted as a descendant of the infamous fraudulent fossil Piltdown Man ...

Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Mechanisms of lithium and cesium enrichment in the Semi-Dazi geothermal field, Qinghai-Xizang Plateau: insights from H–O–Li–Sr isotopes

open access: yesGeothermal Energy
Hot springs in the southern Qinghai-Xizang Plateau show anomalous lithium (Li) and cesium (Cs) enrichment, but the mechanisms driving this enrichment remain poorly constrained.

Method Study for Determination of Penetration Time of Resin-fixed Beds Utilized in TRPO Solvent Purification

open access: yesYuanzineng kexue jishu
The TRPO process is a treatment methodology for high-level waste liquid that has been independently developed in China. This process uses TRPO as an extractant to remove long-lived isotopes such as transuranic elements and highly toxic isotopes such as ...

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

open access: yesThe FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).
