Addressing Known Challenges in Solar Flare Forecasting I: Limb‐Flare Prediction With a 4π Full‐Heliosphere Framework

Space Weather, Volume 24, Issue 2, February 2026.
Abstract A demonstrated failure mode for operational solar flare forecasting is the inability to forecast flares that occur near, or just beyond, the solar limb. To address this shortcoming, we develop a “4π $4{\uppi }$” full‐heliosphere event forecasting framework and evaluate its statistical classification ability against this specific challenge.

Mechanochemical Synthesis of X‐Vinylbenziodoxol(on)es and One‐Pot Conversion to Complex Alkenes**

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
The synthesis of a wide range of complex 1,2‐di(heteroatom)‐substituted (Z)‐alkenes is achieved through a mechanochemical one‐pot reaction of ethynylbenziodoxol(on)es (EBX/EBO) with a variety of heteroatom nucleophiles. The mechanochemical activation enables synthesis of a range of novel vinylbenziodoxol(on)es (VBX/VBO) whose synthesis is inefficient ...

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests

New Phytologist, Volume 249, Issue 4, Page 1992-2009, February 2026.
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Whipped and Mixed Warm Clouds in the Deep Sea

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Turbulence is indispensable to redistribute nutrients for all life forms larger than microbial, on land and in the ocean. Yet, the development of deep‐sea turbulence was not studied in three dimensions to date. As a disproportionate laboratory, an array of nearly 3,000 high‐resolution temperature sensors had been installed for three years on ...

Solid‐State Vortex Laser at Eye‐Safe Band: A Perspective

Nanophotonics, Volume 15, Issue 2, 27 January 2026.
As one of the ideal vortex sources, solid‐state vortex laser at eye‐safe band has attracted considerable attention because of its potentials in multifunctional lidar. In this perspective, we summarize the schemes of eye‐safe vortex laser and discuss prospects for future development.
