Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2787-2826, August 2026.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Analysis of the Charge Structure and Lightning Activity During a Severe Beijing Thunderstorm via an Innovative Balloon‐Borne 3D Electric Field Observation System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

Depth‐Resolved Photo‐Degradation of Perovskite Layer in Solar Cells Stressed Under ISOS Light‐Aging Protocol Conditions: The Role of Substrate, Electron‐Transport‐Layer and Perovskite Deposition Method

Solar RRL, Volume 10, Issue 13, 15 July 2026.
Herein, a depth‐resolved analysis of ambient‐air‐processed perovskite layers employed in carbon‐based hole‐transport‐layer‐free photovoltaics subjected to ISOS light‐aging is provided. In all cases, the light‐induced degradation is demonstrated to start near both top and buried interfaces, and spread into the bulk, affecting perovskite crystals quality,
