NLC-Based Sunscreen Formulations with Optimized Proportion of Encapsulated and Free Filters Exhibit Enhanced UVA and UVB Photoprotection

Pharmaceutics
The topical use of sunscreens is recommended for avoiding the damaging effects of UV radiation. However, improvements are still needed in the existing products to enhance their photoprotection effectiveness and safety. This involves minimizing the use of

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Leaf photoprotection and water relations traits reveal novel axes of coordination and trade‐offs in leaf function

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants can express considerable plasticity in leaf functional traits, but that plasticity may be constrained by coordination and trade‐offs among multiple functions.

Novel Means for Photoprotection

Frontiers in Medicine, 2018
Due to changes in human lifestyle (expanded sunbathing, the use of solaria, etc.) and, most importantly, increasing lifetime and thus higher cumulative exposure to solar radiation, skin aging and skin cancer have become major health issues.

Ascorbate-mediated regulation of growth, photoprotection, and photoinhibition in Arabidopsis thaliana. [PDF]

, 2018
The requirements for ascorbate for growth and photosynthesis were assessed under low (LL; 250 µmol m-2 s-1) or high (HL; 1600 µmol m-2 s-1) irradiance in wild-type Arabidopsis thaliana and two ascorbate synthesis mutants (vtc2-1 and vtc2-4) that have 30%

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.
