Existence of solutions for an eigenvalue problem with weight
In this work we study the existence of solutions for the nonlinear eigenvalue problem with p-biharmonic $ Delta_p^2 u =lambda m(x)|u|^{p-2}u$ in a smooth bounded domain under Neumann boundary conditions.

Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Existence of periodic solutions of duffing equations
As the authors point out in the Introduction ``The main motivation for thus study is a paper by \textit{P. Dràbek} and \textit{S. Invernizzi} [Nonlinear Anal., Theory Methods Appl. 10, 643-650 (1986; Zbl 0616.34010)]''. One studies the problem \(u''(t)+ku'(t)+g(t,u(t))=f(t),\) \(u(0)=u(2\pi)\), \(u'(0)=u'(2\pi)\). To quote again from the Introduction ``

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Existence of Solutions of Riccati Differential Equations
A necessary condition for the existence of the solution of the Riccati differential equation for both linear, time varying systems and nonlinear systems is introduced. First, a necessary condition for the existence of the solution of the Riccati differential equation for linear, time varying systems is proposed.
