With a new grant from the USDA’s National Institute of Food and Agriculture, a team of researchers led by Case Western Reserve University is developing advanced nanocomposite materials for sustainable food-packaging designed to help food stay fresh longer while reducing the environmental impact. 

The Case Western Reserve-led research will focus on developing environmentally friendly packaging materials from renewable biological resources, including plant-based materials, such as corn, wood and agricultural residues.

The team will design biodegradable films that incorporate natural melanin-based nanoparticles. That material will help protect food from microbes, ultraviolet light and oxidation while maintaining mechanical strength, transparency and effective barrier performance.

A study of forests in Nepal’s Annapurna region reveals how elevation and precipitation shape forest structure in the Central Himalaya. Windward slopes support dense, broad-leaved forests, while drier leeward slopes have open, conifer-dominated stands. Despite these differences, overall forest structural complexity remains similar across tree-line ecotones. Elevation and precipitation were identified as the primary drivers of tree height and forest complexity, with tree height declining steadily at higher elevations and structural complexity remaining stable until near the tree line. The findings highlight the importance of considering both topography and climate in forest conservation and management.
