Resource Segmentation: A New Dimension of the Segmentation Hypothesis in Drought Adaptive Strategies and Its Links to Tree Growth Performance.

Plant Cell Environ

January 2025

Qianyanzhou Ecological Research Station, Key Laboratory of Ecosystem Network Observation and Modeling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing, China.

The segmentation hypothesis, a framework for understanding plant drought adaptive strategy, has long been based on hydraulic resistance and vulnerability. Storage of water and carbohydrate resources is another critical function and shapes plant drought adaption and fitness together with hydraulic efficiency and vulnerability. However, patterns and implications of the interdependency of stored water and carbohydrate resources in the context of the segmentation hypothesis are poorly understood.

Genetic Correlations Among Dental, Mandibular, and Postcranial Dimensions in Rhesus Macaques (Macaca mulatta).

Am J Biol Anthropol

January 2025

Department of Medical Anatomical Sciences, College of Osteopathic Medicine of the Pacific-Northwest, Western University of Health Sciences, Lebanon, Oregon, USA.

Objectives: Tooth dimensions typically scale with mandibular and postcranial size in primates, although the exact pattern of scaling varies. This study assesses whether correlations by tissue type, anatomical region, or function (mastication or intrasexual competition) are present and could therefore act as evolutionary constraints on tooth-jaw-body size relationships by estimating genetic and phenotypic correlations between dental, mandibular, and postcranial dimensions in rhesus macaques (Macaca mulatta).

Materials And Methods: The teeth, mandibles, and postcrania of 362 adults from the Cayo Santiago skeletal collection were measured.

Affinity for OH Produces Four-Coordinated Zn Impurities in Hydrated Amorphous Calcium Carbonate.

Inorg Chem

January 2025

Physical and Computational Sciences Directorate, Pacific Northwest National Laboratory, Richland, Washington 99352, United States.

Using ab initio based molecular dynamics and electronic structure calculations, we show that Zn impurities in hydrated amorphous calcium carbonate (ACC) have a much lower coordination number than other divalent impurities due to covalent interactions between the 3d Zn shell and the oxygen atoms of the carbonate and water groups. The local structure around Zn in ACC, including the predicted low coordination number, is confirmed by X-ray absorption spectroscopy of synthetic Zn-bearing ACC. The strong Zn-O chemical interaction leads to substantial water dissociation and slightly disrupts the hydrogen bonding network.

Background: Proso millet bran protein (PMBP), derived from agricultural by-products, possesses high nutritional value, despite its challenging extraction process. The present study proposes an extraction method for PMBP using ultrasound-assisted cellulase technology (UAE), and optimizes the process parameters. Non-waxy (N-PMBP) and waxy (W-PMBP) PMBPs, extracted through alkaline solubilization and acid precipitation (conventional treatment, CT), served as control groups to assess the impact of UAE on the structure and functionality of PMBP, as well as the distinctions between N-PMBPs and W-PMBPs.

Chirality of sub-nanometer nanowires/nanobelts.

Nanoscale

January 2025

School of Chemistry and Chemical Engineering, Beijing Institution of Technology (BIT), Beijing 100081, P. R. China.

Chirality is a widespread phenomenon in the fields of nature and chemicals, endowing compounds with distinctive chemical and biological characteristics. The conventional synthesis of chiral nanomaterials relies on the introduction of chiral ligands or additives and environmental factors such as solvents and mechanical forces. Sub-nanometer nanowires (SNWs) and sub-nanometer nanobelts (SNBs) are one-dimensional nanomaterials with high anisotropy, nearly 100% atomic exposure ratio and some other distinctive characteristics.

The clastic rocks of the Yanchang Formation in the Ordos Basin display poor physical properties but are rich in petroleum resources, exhibiting significant exploration potential. However, due to the existence of multiple sets of oil-bearing formations, hydrocarbon-generating formations, and a large longitudinal span, elucidating the correspondence between crude oil and source rocks is vital for further exploration. This study concentrates on the Lower Yanchang Formation of Triassic in the Yan'an area of the Ordos Basin, aiming to perform refined oil-source correlation.
