A band spectrum attributed to NBr [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1939 Abstract In the course of an investigation on the spectra of the halogens and other substances excited by active nitrogen, Strutt and Fowler (1912) observed that, when bromine was admitted into the glowing nitrogen, a feeble orange luminosity was developed.

Incorporating burn probability into spatial prioritization of woodland caribou habitat restoration
Restoration Ecology, EarlyView.Abstract Introduction Habitat disturbance is a major driver of population declines of woodland caribou in Canada. Habitat restoration is a critical component of a successful, long‐term approach to caribou recovery; however, with limited resources, it is important to target areas where restoration efforts will provide maximum benefits to caribou.

Geoscience Data Journal, Volume 13, Issue 3, July 2026.This work presents AQM‐HLS, a harmonized burned‐area dataset for the Pantanal covering 2014–2024. Landsat‐8/9 and Sentinel‐2 imagery were integrated into multitemporal NBR composites and classified using Random Forest. The dataset captures fire‐scar dynamics, delivering accurate 30‐m burned‐area maps suitable for long‐term monitoring and environmental ...

Magnesium as a conformational gatekeeper of KRAS: Structural dynamics and therapeutic implications
Protein Science, Volume 35, Issue 7, July 2026.Abstract Magnesium serves as an essential cofactor for small GTPases, yet its structural role in regulating KRAS conformational dynamics and nucleotide exchange remains poorly understood. Here, we combine hydrogen–deuterium exchange mass spectrometry (HDX‐MS), native mass spectrometry, and functional assays to elucidate how Mg2+ stabilizes the KRAS ...
