Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

Advanced Science, Volume 13, Issue 17, 23 March 2026.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 155-179, March 2026.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

Micromilling Enhances Iron Bioaccessibility from Wholegrain Wheat [PDF]

Journal of Agricultural and Food Chemistry, 2014
Cereals constitute important sources of iron in human diet; however, much of the iron in wheat is lost during processing for the production of white flour. This study employed novel food processing techniques to increase the bioaccessibility of naturally occurring iron in wheat. Iron was localized in wheat by Perl's Prussian blue staining. Soluble iron
