Glass from Teniky (Madagascar): Geochemical Evidence for Multiple Production Systems and Long‐Distance Exchange in the Mediaeval Indian Ocean

open access: yesArchaeometry, EarlyView.
ABSTRACT The inland rock‐cut site of Teniky, located in the Isalo massif of southern Madagascar, represents an exceptional archaeological context recently dated to the 11th–12th centuries ad, corresponding to the early phases of settlement on the island.

Bioaccumulation and translocation of radionuclides heavy metals in Cynodon dactylon: A phytoremediation approach in Al-Dora refinery

open access: yesJournal of Radiation Research and Applied Sciences
Oil extraction methods such as fracking and drilling can disperse radioactive elements into the environment, posing potential hazards. Certain plants like Bermuda grass can combat this through rhizodegradation, a process that breaks down pollutants into ...

Morphometric analysis of cirques in central Siberia's western Putorana Plateau: a proxy for palaeoclimate

open access: yesBoreas, EarlyView.
A detailed morphometric analysis of 200 cirques across the western Putorana Plateau, central Siberia, was undertaken to investigate cirque development, reconstruct glaciers and infer palaeoclimatic conditions. Cirques are amphitheatre‐shaped landforms with mean length and widths of 936 and 1000 m, respectively, indicating a mature glacial landscape ...

Oral Butyrate Reduces Progression of Kidney Damage in an L‐NAME‐Induced Diabetic Kidney Disease Mouse Model

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Diabetic kidney disease (DKD) is one of the main causes of kidney failure worldwide. Interestingly, patients affected by DKD are characterised by a low abundance of gut bacteria producing short fatty acids including butyrate, which is suggested to play a role in the decline of renal function.

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).

Overlooked components of lipid metabolism: Odd‐chain polyunsaturated fatty acids in photosynthetic microorganisms

open access: yesJournal of Phycology, EarlyView.
Abstract This mini‐review examines odd‐carbon polyunsaturated fatty acids (odd‐PUFAs), a rare but biologically significant group of fatty acids in photosynthetic microorganisms. Odd‐PUFAs are straight‐chain fatty acids containing an odd number of carbon atoms and two or more methylene‐interrupted double bonds. They typically account for less than 1% of

STUDY OF RADIOACTIVE DECAY IN ENVIRONMENTAL AND HEALTH CONTEXTS

open access: yesWorldwide Journal of Physics
Radioactive decay is a fundamental physical process with wide-reaching implications for environmental safety and public health. This study explores the impact of naturally occurring and anthropogenic radioactive isotopes, such as uranium-238, thorium-232,

Reciprocal transport of carbon and nitrogen between plants and the hyphosphere microbiome in a temperate grassland

open access: yesNew Phytologist, EarlyView.
Overview of the experimental design and 13CO2 pulse‐labeling approach in the field. Summary Despite its relevance for plant nutrient acquisition, the role of the hyphosphere in structuring fungal–bacterial networks and mediating carbon–nitrogen (C–N) exchange under field conditions remains unclear.

Integrated Metabolomics and Selection Signal Analysis Provide Insights Into the Selection for Flavonol Biosynthesis Associated With Lettuce Quality Improvement

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Lettuce is a critical leafy vegetable consumed worldwide and is a substantial dietary source of health‐promoting compounds. Exploring changes in metabolism during lettuce domestication under artificial selection conditions is important to facilitate further breeding and cultivation for quality improvement.
