Phaeocystis Dominance of a Large‐Scale Productivity Anomaly in the Northeast Atlantic Ocean During Spring 2024

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Changes to the North Atlantic spring bloom phytoplankton community structure are expected in response to regional warming trends. In 2024 an extensive body of low chlorophyll water, covering approximately 720,000 km2 in area, dominated the Northeast Atlantic during the peak of the spring bloom period.

The metabolic ability of swallowtails results in the production of bioactive substances from plant components.

PLoS ONE
Host plant selection may depend on the metabolic system in herbivorous insects. Although oligophagous insects take up specific host plant components, how host plant components and their biological activities are altered through their metabolic systems ...

Desiccation tolerance mechanisms in the green lineage and beyond

New Phytologist, Volume 251, Issue 6, Page 3159-3175, September 2026.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.
