Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

open access: yesGeological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Cigarette Smoke Exposure Attenuates T2R‐Mediated Apoptosis in Head and Neck Squamous Cell Carcinoma

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Tobacco use is associated with worse outcomes in head and neck squamous cell carcinoma (HNSCC). Bitter taste receptor (T2R) activation induces apoptosis via calcium‐dependent signaling, and higher T2R expression correlates with increased survival in HNSCC.

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

open access: yesInterdisciplinary Materials, EarlyView.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

Tin‐based perovskite light‐emitting diodes: Progress and perspective

open access: yesInfoScience, EarlyView.
This review assesses tin‐based perovskite light‐emitting diodes (PeLEDs), focusing on the limitations of Sn2+ oxidation–induced defects and uncontrolled crystallization. By evaluating advanced device engineering and structural innovations, this article highlights their viability in narrowband pure‐red displays and near‐infrared optical communication ...

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...
