In‐vivo pilot study to assess a new plant‐based cosmetic formulation containing Ziziphus joazeiro bark extract and Apium graveolens seed extract for the improvement of dandruff while enhancing scalp microbiome balance and barrier function in subjects with oily to dry sensitive scalps

International Journal of Cosmetic Science, Volume 48, Issue 1, Page 51-69, February 2026.
This study comprising dermatological as well as microbiome analysis indicates that mild‐to‐moderate dandruff symptoms can successfully be reduced with a plant‐based shampoo by restoring the bacterial scalp microbiome balance, suggesting a ‘microbiome‐friendly’ formulation tolerated excellently for oily scalp and sensitive scalp.

Pol‐NIC: An open database on pollen nutrients, imaging, and contaminants

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Pollen is a key component of pollinators' nutrition, yet information on its nutrient composition is largely missing from floral trait datasets. These data paper compiles existing data for 283 plant species and adds new multidimensional analyses of cultivated and wild plants to address major knowledge gaps, along with photos of pollen grain morphology ...

Integrating target capture with whole genome sequencing of recent and natural history collections to explain the phylogeography of wild‐growing and cultivated cannabis

PLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1771-1788, November 2025.
Cannabis has been used by humans for millennia, resulting in diverse landraces and uses. Its complex legal status and economic importance make sampling wild‐growing populations difficult, limiting past studies to modern cultivars with low genetic diversity. Our research provides crucial insights into the genetic diversity of wild‐growing and cultivated

Misplaced fears? What the evidence reveals of the ecological effects of tidal power generation

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Marine energy (tidal range and stream/flow) is a dependable and clean power source that stands out as a compelling alternative to fossil fuels. Despite widespread concerns surrounding the ecological effects of tidal energy infrastructure, we find few of these are substantiated by evidence or long‐term monitoring of existing tidal power projects.
