Mental health benefits of urban green—A systematic review and meta‐analysis of 56 pre‐post control experiments

open access: yesPeople and Nature, Volume 8, Issue 4, Page 808-834, April 2026.
Abstract Background. Fostering healthy urban living conditions is a critical public health objective. One efficient approach lies in the contact to nature, as numerous studies have shown that urban and peri‐urban natural elements both indoors and outdoors carry a large potential in buffering typical urban threats to mental health.

Exploring the Therapeutic Potential of Cannabidiol in Cutaneous Squamous Cell Carcinoma: An Integrated Computational and Experimental Study

open access: yesInternational Journal of Quantum Chemistry, Volume 126, Issue 5, March 5, 2026.
Cannabidiol (CBD) exhibits increased reactivity, stronger CB1 receptor binding, and enhanced cytotoxicity against A431 squamous carcinoma cells compared to 5‐fluorouracil (5‐FU). Integrated DFT, molecular docking, and experimental analyses demonstrate CBD's improved stability and binding affinity, highlighting its potential as an alternative ...
