Evaluation of Phantom Doping Materials in Quantitative Susceptibility Mapping

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1545-1556, October 2026.
ABSTRACT Purpose To measure magnetic susceptibility (χ) with Quantitative Susceptibility Mapping (QSM) and evaluate its repeatability using four phantom doping materials relevant to QSM applications. Methods A cylindrical phantom was constructed containing vials of agarose gel doped with two paramagnetic materials (ferritin, USPIO) and two diamagnetic ...

Unraveling the Power of Disorder: A Bioinspired Cuttlebone Structure With Superior Strength, Energy Absorption and Isotropy

Advanced Science, Volume 13, Issue 43, 3 August 2026.
Cuttlebone‐inspired architected metamaterials introduce controlled structural disorder to simultaneously enhance strength, energy absorption, and compressive stability. Tunable disorder suppresses shear anisotropy, outperforms periodic lattices, and establishes discrete randomness as a robust route to high‐performance lightweight mechanical ...

The Effects of Suspended Sediments, Dye, and Their Variation on Fish Behavior

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Human activities are affecting the visual environments of freshwater ecosystems by introducing visual pollutants such as artificial dyes and elevated suspended sediment levels. Our research shows that dyes and suspended sediments can have contrasting effects of fish behavior, with dye increasing and sediments decreasing movement.

Searching for the beasts in the archive as methodological praxis

Geographical Research, Volume 64, Issue 3, August 2026.
This article offers searching for the beasts in the archive as a methodological tool available to researchers invested in both anticolonialism and antianthropocentrism. By focusing on three basic units of reference—categories, histories, and borders—the article shows how searching for the beasts unsettles some taken‐for‐granted assumptions that ...

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, Volume 16, Issue 7, Page 1314-1327, July 2026.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,
