Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

Advanced Functional Materials, Volume 36, Issue 68, 24 August 2026.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Protective Potential of Vinpocetine on Acrylamide Induced Liver Toxicity in Male Albino Rats

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
This study sought to assess the protective effects of vinpocetine, a synthetic analog of the natural alkaloid vincamine exhibiting strong antioxidant and anti‐inflammatory properties against ACR‐induced hepatic injury. Co‐administration of vinpocetine mitigated the ACR‐induced alterations and help in normalization of biochemical parameters, enhancing ...

Beet leafhopper transmits virescence of periwinkle

California Agriculture, 1977
Photo above shows healthy periwinkle on left and virescence-affected periwinkle on right; plant on right was exposed to beet leafhopper (Circulifer tenellus) that had previously fed on another virescence-affected periwinkle.

Multi‐metric complexity drives ecological succession on blue‐green infrastructure across scales

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Our findings demonstrate that restoring coastal habitat complexity can substantially improve ecosystem diversity and functioning, offering a scalable marine conservation approach within increasingly engineered seascapes. We highlight the need for multi‐metric, multi‐scale assessments of spatio‐temporal community formation on eco‐engineered ...

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

Plant Biotechnology Journal, Volume 24, Issue 8, Page 4823-4843, August 2026.
ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

Step by step: Floral structure and developmental changes to the formation of the gynostegium in Apocynaceae s.l.

Plant Biology, Volume 28, Issue 5, Page 1467-1480, August 2026.
Developmental changes in Apocynaceae s.l. reveal progressive reductions in the corolla tube and epipetaly, together with increased staminal tube formation, highlighting shifts in floral integration associated with gynostegium evolution and organization.

Metabolic reprogramming of periwinkle plant culture [PDF]

Nature Chemical Biology, 2009
We transformed an alkaloid biosynthetic gene with reengineered substrate specificity into Catharanthus roseus. The resulting transgenic plant cell culture produced a variety of unnatural alkaloid compounds when cocultured with simple, achiral, commercially available precursors that the reengineered enzyme was designed to accept.

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

Journal of Surfactants and Detergents, Volume 29, Issue 4, Page 537-547, July 2026.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Picking a way forward: valuing and managing traditional shellfish gathering for Littorina littorea

Aquatic Living Resources, 2018
Littorina littorea (periwinkles) have been harvested by hand picking from the shore since prehistoric times. Harvests are generally unregulated, catches are not linked to particular shores and fisheries statistics are considered to be unreliable.
