Selective Hydrodemethylation of Methylalkylbenzenes on Potassium Hydride

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Selective catalytic hydrodealkylation of methylalkylbenzenes on carbon‐supported potassium hydride is reported. The reaction exhibits a reactivity trend of 1° ∼ 2° ∼ 3° < CH3, which is opposite to traditional dealkylation and hydrodealkylation. DFT calculations on the (001) facet of KH with ortho‐ethyltoluene suggest that selectivity is controlled by ...

African Decolonial Theory: A Conversation

Antipode, Volume 58, Issue 2, 2026.
Abstract Antipode has become a key platform for engaging with decolonial and anticolonial scholarship, as well as adjacent fields such as Black geographies, Indigenous studies, Latin American feminism, and work on settler‐colonialism. African reference points in this literature, however, have been far less common, both in the journal and more broadly ...

Global Patterns and Gaps in Research on Salinity Tolerance of Inland Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 400-411, March 2026.
ABSTRACT Freshwater salinization is an emerging threat impacting approximately one‐third of the world's freshwater bodies. However, the salinity tolerance of many inland fishes remains understudied, despite being a crucial factor in determining species distributions and fitness.

Clustering sperm: A statistical approach to identify sperm morph numbers in the Drosophila obscura species group

Physiological Entomology, Volume 51, Issue 1, Page 48-62, March 2026.
Most Drosophila species, such as D. melanogaster, make one type of sperm, while the obscura species group produces multiple sperm morphs, with different total lengths and nuclear lengths. The pseudoobscura species subgroup produces three sperm morphs (one long, two short). This is a derived feature as other sub‐groups produce two sperm morphs.
