Meteorological Applications, Volume 33, Issue 3, May/June 2026.The Upper Paraguay River Basin faced intense droughts in 1999, 2007, and 2010, coinciding with extensive wildfires. In 2007, a severe drought episode affected 97.5% of its area. These extreme years were characterized by pronounced negative anomalies and shifts in atmospheric moisture contributions from key source regions, during dry season. ABSTRACT In

The Influence of Fluvial Incision on the Lithospheric Stress Field: A Numerical Approach
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Erosion along large fluvial valleys transports important sedimentary volumes across continents over geological time, modifying the loads imposed on the lithosphere and inducing isostasy‐related subsurface stresses. This work presents numerical experiments with a visco‐plastic lithosphere aimed at understanding the distribution and evolution of

Impact of Mantle Velocity Uncertainty on Receiver‐Function Imaging of the Transition Zone
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Seismological estimates of the 400‐km and 670‐km mantle discontinuities (d400 and d670) are crucial for understanding the thermochemical structure and dynamics of the mantle transition zone (MTZ). However, artifacts from using ray theory and uncertainties in mantle velocity structure can affect topographic mapping of these boundaries.

Laser‐Enabled Nanopinholes for Silicon Solar Cells with Polycrystalline Si/SiOx Passivating Contacts
Solar RRL, Volume 10, Issue 8, 27 April 2026.Conductive nanoscale pinholes are created by selective heating of pyramid tips on randomly textured silicon via pulsed laser irradiation. Due to heat concentration at the pyramid tips, the dielectric passivating layer is selectively opened at the pyramid tips.

Shape‐Changing Multiphase Microparticles from Complex Liquid Crystal Emulsions
Advanced Functional Materials, Volume 36, Issue 35, 30 April 2026.Liquid crystalline network (LCN) microparticles are prepared from single, double (Janus), and triple emulsions through a simple and scalable bulk‐emulsification strategy. Under heating, the particles exhibit robust, reversible, large‐amplitude deformations that depend both on the morphology and the liquid crystals director field configuration.
