Age, growth, and population structure of the African cuttlefish Sepia bertheloti based on beak microstructure

open access: yes, 2023
In this study, we explored the feasibility of using the beaks of the African cuttlefish Sepia bertheloti for age estimation and growth analysis. The rostrum sagittal section (RSS) of the lower beak was the most suitable region in the species.

Searching for the beasts in the archive as methodological praxis

open access: yesGeographical 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

open access: yesFEBS 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,

Batteries From Reused, Recycled, and Surplus Materials

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...
