Dual mechanisms give rise to biphasic stomatal opening in onion

New Phytologist, Volume 252, Issue 5, Page 1976-1987, December 2026.
Anisotropic guard cell wall stiffness enhances onion stomatal pore opening by increasing guard cell arc length. Summary Stomata are controllable micropores on the leaf surface that regulate gas exchange and water loss. Pore aperture adjustment is a mechanical process whereby changes in guard cell turgor drive changes in cell shape, resulting in ...

Targeted marine cloud brightening can dampen El Ni\~no [PDF]

Many record-breaking climate extremes arise from both greenhouse gas-induced warming and natural climate variability. Marine cloud brightening, a solar geoengineering strategy originally proposed to reduce long-term warming, could potentially mitigate ...

Probing the Radio Counterpart of Gamma-ray Flaring Region in 3C 84

EPJ Web of Conferences, 2013
The radio source 3C 84 associated with the radio/giant elliptical galaxy NGC 1275 is one of the best targets to probe the radio counterpart of the γ-ray emitting region.

Temporal and angular variation of the solar limb brightening at 17 GHz

, 2003
In order to better understand the atmosphere structure of the Sun, we have analyzed over 3000 daily maps of the Sun taken at 17 GHz from the Nobeyama Radioheliograph (NoRH) from 1992 through 2001, focusing on the excess brightness temperature observed ...

Model‐Data Comparison of Electron Energization Associated With Kinetic Alfvén Waves in the Near Earth Magnetotail

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract A model‐data comparison between Gyrofluid‐Kinetic Electron simulations and MMS satellite observations of kinetic Alfvén waves (KAW) and associated electron energization in the near Earth magnetotail is presented. The observations reveal 10 keV electron beams embedded within intense KAW field‐aligned currents.

Station‐Based Assessment of Sub‐Seasonal Climate Trends in the Tyrolean Alps (Austria)

International Journal of Climatology, Volume 46, Issue 13, 15 November 2026.
In this study, we quantify the magnitude and significance of sub‐seasonal trends in the Tyrolean Alps (Austria) by collecting, processing and analysing meteorological observations from a dense network of climate stations. Our analysis indicates a warming rate of 0.43°C/dec over 1964–2023, greater sub‐seasonal trend variability when the analysis window ...

Two-stage Nature of a Solar Flare with Parallel and Semicircular Ribbons

The Astrophysical Journal
Flare ribbons with parallel and circular morphologies are typically associated with different magnetic reconnection models, and the simultaneous observation of both types in a single event remains rare. Using multiwavelength observations from a tandem of

Multi‐Biomimetic Structural Colors Inspired by Pearls and Bird Feathers

Advanced Materials, Volume 38, Issue 62, 6 November 2026.
A dual‐biomimetic strategy mimicking pearls and bird feathers is proposed to construct full‐gamut structural colors. By integrating a non‐strictly periodic inorganic multilayer architecture with tunable light absorbers, this facile approach circumvents the complex fabrication of traditional 1D photonic crystals, offering immense potential for cosmetics,

Sungrazer comets as analogs of star-planet magnetic interactions

Astronomy & Astrophysics
Context. Star–planet magnetic interactions (SPMIs) can transfer energy from an exoplanet to its host star via Alfvén waves when the planet orbits within a sub-Alfvénic stellar wind.
