In-Vivo Dosimetry for Ultra-High Dose Rate (UHDR) Electron Beam FLASH Radiotherapy Using an Organic (Plastic), an Organic–Inorganic Hybrid and an Inorganic Point Scintillator System

Photonics
Dosimetry is crucial in radiotherapy to warrant safe and correct treatment. In FLASH radiotherapy, where ultra-high dose rates (UHDRs) are used, the dosimetric demands are more stringent, requiring the development and investigation of new dosemeters.

Demonstration of a family of X‐ray dark‐field retrieval approaches on a common set of samples

Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 437-447, March 2026.
This study aims to guide users of dark‐field imaging in selecting the most suitable technique for their imaging goals. To this end, we provide a summary table and highlight opportunities for future research into the sources of dark‐field contrast across emerging methods.There are various imaging setups capable of capturing dark‐field images, each with ...

Al‐Khadhaf: The first camera‐observed (H5–6) meteorite fall from Oman

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 522-547, March 2026.
Abstract A fireball camera system installed in 2022 by the Oman Meteorite Monitoring Project (OMMP) as part of the Global Fireball Observatory (GFO) recorded a 3.2 s fireball on March 8, 2022 at 8:15 p.m. UTC. A meteoroid of 4 ± 2 kg entered the atmosphere at 14.0 km/s.

SALT OVERLY SENSITIVE 1 Na+/H+ Exchanger Operates in Mature Root Zone and Is a Major Contributor to Root Na+ Exclusion During Shoot‐to‐Root Na+ Recirculation

Plant, Cell &Environment, Volume 49, Issue 3, Page 1650-1660, March 2026.
ABSTRACT The Na+/H+ antiporter SALT OVERLY SENSITIVE 1 (SOS1) is a key component of Na+ exclusion and plant salt tolerance. Although previous studies have suggested that SOS1 functions in both the root apex and mature root zone, their contributions remain unclear due to limited methodological resolution and originated mostly from transcriptional ...

Fatty acids and glycerides are object recognition and carrying cues for foraging Camponotus modoc carpenter ants

Physiological Entomology, Volume 51, Issue 1, Page 29-39, March 2026.
Colour‐coded perlites were treated with specific fatty acids or mono‐, di‐ or triglycerides as perlite pickup cues for laboratory and field colonies of western carpenter ants. In laboratory and field experiments, ant colonies were offered multiple choices of these colour‐coded lipid‐treated perlites for pickup and transport to the nest.

Corona Discharges Glow on Trees Under Thunderstorms

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Coronae, which are weak electrical discharges, have long been hypothesized to form on trees under thunderstorms, though never directly observed, characterized, or quantified. Using a newly developed instrument that measures ultraviolet emissions from coronae, the first direct observations and quantifications of coronae are presented for two ...

Thousand Years of Nitrogen Oxide Sources in Western Europe: Evidence From Nitrogen Stable Isotopes (δ15N) of Nitrate in a Mont Blanc Ice Core

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Nitrogen stable isotopes (δ15N) of ice core nitrate (NO3−) are often subject to diverse interpretations associated with changes in nitrogen oxide (NOx) sourcing, atmospheric reactions, and/or post‐depositional processes. Here, an ice core from Mont Blanc (French Alps) was analyzed to investigate the δ15N(NO3−) record over the past 1,000 years.
