Researchers found waste eggshells can become a fine powder for mortar. This powder replaced cement, showing no reduction in compressive strength. The strongest results occurred when ten percent eggshell powder was used. Higher amounts increased porosity and weakened the mortar's internal structure. This study highlights a sustainable method for construction materials.

A trio of African wild dog brothers undertook a remarkable odyssey covering 4,126 kilometers across Zambia. This unprecedented trek marks the longest documented dispersal by a mammal in Africa. Their journey through various terrains, including natural reserves and areas impacted by humans, highlights the crucial need for habitat connectivity beyond national park borders, revealing pressing conservation issues faced by species that require large ranges.
