Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT This study introduces a novel velocity‐iterative directional annealing (IDA) strategy to overcome stagnation challenges in columnar grain growth of Ti‐48Al‐2Cr‐2Nb alloys. By dynamically adjusting hot zone migration rates across iterative cycles, the IDA protocol achieved 92.2% synchronization between anisotropic α‐grain boundary (GB ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The limited osteogenic capacity of magnesium phosphate cement (MPC) has constrained its biomedical applications, underscoring the necessity to develop MPC with enhanced physical properties and bone‐forming capabilities. In this study, a multifunctional MPC system was developed by incorporating zoledronic acid‐loaded near‐infrared (NIR ...
