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,

An Investigation into Hybrid Rocket Injectors

, 2020
Propulse NTNU er et nylig oppstartet rakettlag for studenter som nå forsøker å bygge en hybrid-rakett. Fordi dette er en ny organisasjon er det et behov for å samle kunnskap om hvordan raketter og deres nøkkelkomponenter fungerer. En av nøkkelkomponentene er injektoren, og dens rolle er å levere en spesifik massestrømningsrate av flytende oksidant som ...
