ORMDL Proteins Turnover via Proteasome and Autophagy Is Cell‐Type Dependent and Tied to Ceramide Homeostasis

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.

Magnetic and Isotopic Analyses Unravel the Abundance and Sources of Magnetic Nanoparticles in Urban PM2.5

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Magnetic nanoparticles (NPs) are increasingly recognized as an emerging threat to ecosystems and human health, yet their mass concentrations and sources in urban atmosphere remain poorly characterized. Here, we developed a robust methodology for the extraction, quantification, and source apportionment of magnetic NPs in urban PM2.5.

A 500‐kyr Pluvial Interval Triggered Lacustrine Carbon Burial in Late Cretaceous East Asia

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The early Late Cretaceous hothouse was featured by intense storms and a prevailing monsoon climate, yet direct evidence for regional extreme precipitation events is rare. Here, we reconstruct local weathering and hydrological processes using magnesium and strontium isotopes (δ26Mg and 87Sr/86Sr) from lacustrine dolostones in the Upper ...

Sulfur‐Stabilized High Entropy Oxysulfides Enable Efficient CC Bond Cleavage in Ethylene Glycol Electrooxidation for Sustainable Plastic Upcycling to Formate

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Room‐temperature synthesis method of high‐entropy oxy‐sulfide (HEOS) is introduced. Compared to high‐entropy oxides (HEO), sulfur incorporation promotes oxygen vacancy stabilization and facilitates CC bond cleavage, improving efficiency of ethylene glycol electrooxidation to formic acid. Lower cell overall voltage enables sustainable plastic upcycling
