How PM2.5 wrecks your airways and how the damage might be reversed

Immunology Frontier Research Center (IFReC) - Osaka University
Peer-Reviewed Publication

Researchers from The University of Osaka found that PM_2.5 air pollutants negatively affect mucociliary clearance, a protective mechanism of the respiratory tract. Air pollution led to the formation of lipid peroxide-derived aldehydes, known to damage protective cells in the airway and increase the risk of infections. ALDH1A1 was found to play an important role in protection against aldehydes, making it a potential therapeutic target to diminish the negative effects of air pollution.

Van der Waals bilayers: Monolayer stiffness stabilizes ferroelectricity above RT

Advanced Institute for Materials Research (AIMR), Tohoku University

Certain 2D van der Waals bilayers, such as WTe₂ and h-BN, exhibit sliding ferroelectricity, yet its stability above room temperature remained unexplained. AIMR researchers developed a thermodynamic model linking this stability to monolayer stiffness. Their findings reveal a soft “sliding phonon” governing the phase transition, with implications for next-generation nanoelectronics.
