Enhanced Adiabatic Heating Drives Faster Warming of Early Summer Hot Extremes in North China

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract North China has recently seen frequent hot days above 35°C or even 40°C before or at the very beginning of June. This raises a concern about the changing seasonality of exceptional hot extremes in the region which might leave population there underprepared.

Enhancing Chimeric Fragmentation Spectra Deconvolution Using Direct Infusion–Tandem Mass Spectrometry Across High‐Resolution Mass Spectrometric Platforms

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Direct infusion mass spectrometry (DI‐MS) is a rapid analytical technique widely used in omics research and other fields. However, the complexity of DI‐MS spectra frequently leads to co‐fragmentation of analytes with similar m/z, resulting in chimeric fragmentation spectra that complicate compound identification.

Microcystin‐LR Triggers Renal Tubular Ferroptosis Through Epigenetic Repression of GPX4: Implications for Environmental Nephrotoxicity

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
MC‐LR stabilizes DNMT1/3a by blocking their ubiquitin‐mediated degradation, leading to Gpx4 promoter hypermethylation and E2F4/NCoR‐associated transcriptional repression, which drives renal tubular ferroptosis in mice. Pharmacological inhibition of DNA methylation (SGI‐1027) or ferroptosis (Fer‐1) disrupts this DNMT‐GPX4 axis, thereby alleviating MC‐LR‐
