Radiocarbon Reveals Modern Carbon Exchange With Topsoil Inorganic Carbon in Drylands

Global Change Biology, Volume 32, Issue 9, September 2026.
Radiocarbon measurements across drylands reveal that topsoil inorganic carbon carries a measurable modern carbon signature linked to soil pH and organic carbon pools. This modern imprint weakens with increasing aridity and soil depth, indicating reduced exchange with contemporary carbon sources under drier conditions and in deeper soils.

Degradation of Silicate Glass Used as Fine Aggregate in Concrete

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT A large body of literature has previously reported on the deleterious expansion which occurs if recycled soda lime silica (SLS) bottle glass is used as fine aggregate in concrete cast with ordinary Portland cement (OPC). It is theorized that this expansion is due to a propensity for the formation of a volume‐expanding alkali–silica reaction ...

Microstructural evidence for multiple generations of sulfide precipitation and impact‐induced thermal alteration under acidic conditions on Asteroid Ryugu

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2201-2217, September 2026.
Abstract Here we report on the microstructure and chemistry of sulfide minerals returned from asteroid (162173) Ryugu. We identify a unique sulfide population in particle A0016 composed of violarite (FeNi2S4), pyrite (FeS2), chalcopyrite (CuFeS2), pyrrhotite (Fe1‐xS), and pentlandite ([Fe,Ni]9S8).

Nature, origin, and phosphorylation potential of the phosphorus/sulfur‐bearing nanoscale multiphasic assemblages in the CM chondrites Murchison and Murray

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2303-2335, September 2026.
Abstract Carbonaceous chondrites contain phosphorus, whose speciation and thus history remain to be investigated. Phosphorus/sulfur‐bearing assemblages have been reported in carbonaceous CM chondrites, but there is no consensus about their exact compositions and origins.

Soil remineralization with silicate rock powder: nutrient effects on plant quality and ungulate foraging

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Silicate rock powder (SRP), a slow‐release mineral additive, is increasingly used as a potential mitigation measure against soil acidification in natural areas. SRP addition has led to a higher soil base saturation and small increases in soil nutrient availability.
