The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Determination of strontium 90 in environmental materials. [PDF]

open access: yes, 1967
A method for determining strontium 90 in environmental materials is described. It consists of the ion-exchange separation of strontium from calcium at an elevated temperature by careful control of pH and the molar ratio of Ca:EDTA, followed by scavenging,

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5563-5579, August 2026.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Mechanical Loading Induces Distinct and Shared Responses in Endothelial and Muscle Cells and Reveals Exercise‐Like Molecular Profiles

open access: yesThe FASEB Journal, Volume 40, Issue 14, 31 July 2026.
Mechanical loading of human endothelial and muscle cells induced several distinct and shared molecular responses, many of which are commonly observed after exercise in vivo. Both cell types secreted acetate and endothelial cells increased serine synthesis from glucose.

Exercise Modalities to Preserve Muscle Mass and Bone Health After Metabolic Bariatric Surgery

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 3, June 2026.
ABSTRACT Background Metabolic bariatric surgery (MBS) effectively reduces fat mass (FM), but how to best preserve muscle and bone mass after MBS is unknown. Objective This study aimed to evaluate the effect of aerobic, resistance and combined exercise regimens on body composition, bone mineral density (BMD) and physical function in adults following MBS.

Middle Cretaceous Andean‐Type Arc Evolution in the Sanandaj–Sirjan Zone (Shalair Valley), Iraq: New Geochronological and Geochemical Constraints

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The middle Cretaceous granitoid plutons of the Shalair Valley, situated in northeastern Iraq, constitute a principal magmatic component of the Sanandaj–Sirjan Zone within the northwestern segment of the Zagros Orogenic Belt. Among these plutons, the equigranular Aulan body (AG) and the porphyritic Laladar body (LG) were crystallized at 111.0 ±
