In a new study, researchers have developed a low-cost and eco-friendly method to extract gold from electronic waste using the leaves of the plant Lagerstroemia speciosa, commonly called the Pride of India. They have applied the principle of biosorption—the ability of biological materials in an aqueous solution to bind with heavy metals—to extract gold from wastewater.
A new review reveals that rising global temperatures, increased pollution, and extreme weather events are driving a global surge in eye diseases, disproportionately affecting vulnerable communities and challenging healthcare systems.
