Fossil freshwater fishes from the Pliocene of northern Colombia and the palaeogeography of northern South America

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Freshwater fishes from the northwestern Colombian Andes are reported from the Pliocene Sincelejo and Ware formations. A total of 10 taxa have been identified, involving two orders, five families and nine genera. Characters from dental morphology, fin spines and cranial bones are provided as taxonomic tools for the study of fossil fishes.

Optimization of Potassium Carbonate and Oil‐Based Dipping Pretreatments to Enhance Drying Rate and Quality of Sun‐Dried and Hot‐Air‐Dried Red Pepper

Journal of Food Process Engineering, Volume 49, Issue 7, July 2026.
Optimized potassium carbonate–oil dipping pretreatments significantly accelerated sun drying of red peppers (up to 39%). Hot air drying enhanced pungency and ascorbic acid content, while whole peppers better preserved carotenoids compared to chopped samples. ABSTRACT The effects of dipping pretreatments (potassium carbonate + olive oil or ethyl oleate),

Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

TAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...

“Humanizar”: aprendizajes sobre alteridad, salud y futuro en una experiencia de investigación compartida

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT The visit to Bogotá of a fééeneminaa (Muinane) friend, Célimo Nejedeka Jifichíu, and in particular, his work in researching and transmitting traditional health knowledge, offer the pretext to navigate the relationship between elements that at first glance seem distant from each other: indigenous imaginaries about otherness, their visions of ...

Tamoxifen‐Based Dimers: Design, Synthesis, Cell Viability Evaluation on Breast Cancer Cells, and Computational Insights

Archiv der Pharmazie, Volume 359, Issue 5, May 2026.
This study explores the design, synthesis, and evaluation of tamoxifen‐derived dimers as potential therapeutics for ER+ breast cancer. The new compounds exhibit improved IC50 values and selective cytotoxicity compared with tamoxifen. They promote apoptosis through a cell cycle‐independent pathway, highlighting their potential as promising alternatives ...

Recursive and Cyclic Constructions for Double‐Change Covering Designs

Journal of Combinatorial Designs, Volume 34, Issue 4, Page 198-209, April 2026.
ABSTRACT A double‐change covering design (DCCD) is a v‐set V and an ordered list L of b blocks of size k where every pair from V must occur in at least one block and each pair of consecutive blocks differs by exactly two elements. It is minimal if it has the fewest blocks possible and circular when the first and last blocks also differ by two elements.

Leaf Litter Decomposition in the Tropics Dynamically Recovers Following Experimental Disturbance Across Temporal Scales

Biotropica, Volume 58, Issue 2, March 2026.
Litter decomposition by arthropods and microbes is a key ecosystem process in tropical forests, yet its response to disturbance and forest regeneration remains poorly understood. To investigate decomposition dynamics across forest succession, we conducted a space‐for‐time study in the Ecuadorian lowland Chocó spanning active cacao plantations and ...
