Terminal Proterozoic cyanobacterial blooms and phosphogenesis documented by the Doushantuo granular phosphorites II: Microbial diversity and C isotopes [PDF]

, 2014
An unprecedented period of phosphogenesis, along with massive deposition of black shales, major perturbations in the global carbon cycle and the rise of atmospheric oxygen, occurred in the terminal Proterozoic in the aftermath of the Marinoan glaciation.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Detection of Different Pesticide Residues in Seasonal Leafy Vegetables of North Bengal Region, Bangladesh

Public Health Challenges, Volume 5, Issue 2, June 2026.
FTIR spectroscopy detected multiple pesticide residues—thiamethoxam, carbendazim, mancozeb + metalaxyl, and dimethoate—in commonly consumed leafy vegetables from North Bengal, Bangladesh. These findings highlight potential food safety risks and emphasize the need for regular monitoring and safer pesticide management practices.

Estratigrafía de Sr y evolución sedimentaria de los depósitos marinos del Mioceno temprano en el antepaís del norte de la Cuenca Austral (o Magallanes), Argentina [PDF]

, 2015
Early Miocene shallow marine deposits in the region of Lago Posadas-Meseta Belgrano (Argentina) represent part of the “Patagoniense” transgression, an Atlantic marine incursion that flooded large part of Patagonia, including the Austral (foreland) Basin (

Morphological and Morphometric Analysis of Animal Hair From 18th Century Burial Sites in Mazamet (Southwest France)

Archaeometry, Volume 68, Issue 3, Page 500-511, June 2026.
ABSTRACT Morphological and morphometric analysis of archaeological animal hairs offers a nondestructive method to explore past clothing. We examined hair from two 18th‐century burial areas (SP03 and SP04) in Mazamet, France. SP03 specimens exhibited a continuous medulla, a low medullary index (0.2 ± 0.03) and cuticular features suggesting goat or ...

Human Response to Postglacial Sea Level Change in Jomon Prehistoric Sites Around Lake Ogawara, Northern Japan

Geoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT The Jomon culture, characterized by hunting, gathering, and fishing, lasted from approximately 15.5–2.4 ka in the Japanese archipelago. In this study, the shore of Lake Ogawara in northeastern Japan was investigated using coring, fossil analyses, and radiocarbon dating to reconstruct the palaeoenvironmental changes as well as their ...

Eco‐Friendly Preparation of Porous Starch via Water‐Induced Amylose Solubilization

Polymers for Advanced Technologies, Volume 37, Issue 5, May 2026.
ABSTRACT Starch is a safe and biocompatible excipient in pharmaceutical formulations. Introducing pores into its granules transforms it into a biodegradable carrier suitable for drug delivery. Various strategies have been developed to induce pore formation, including physical methods (e.g., microwave, ultrasound), chemical methods (e.g., solvent ...
