The Argentine cactus moth, an invasive species from South America, has begun its march across the southern United States, threatening the delicate balance of native prickly pear cactus populations. Initially identified in Florida in 1989, its westward movement raises alarms among scientists regarding potential ecological disruptions in the southwestern U.S. and Mexico. Control measures, including the sterile insect technique, are in place to monitor and manage its spread.

Archaeologists have made an exciting discovery in Nagaland's Noklak district, uncovering pottery fragments that are approximately 3,500 years old. This revelation extends the timeline of human occupancy in Northeast India. The site also yielded stone tools and charred cereal remnants, hinting at a more intricate pattern of human migration and the development of agriculture. Continued exploration is anticipated to reveal even more about this ancient past.

Apollo 15 astronauts found unusual green flecks on the Moon's surface. These flecks were later identified as volcanic glass beads containing trapped water. Researchers discovered hydrogen within these tiny beads, proving lunar water existed. This finding challenged the long-held belief that the Moon was extremely dry. The discovery revealed significant water presence deep within the Moon's interior.

Delhi-NCR twins Naina and Nayantara Singh developed a plant-based water purification system. Their innovation, Aqua Sattva, uses okra, fenugreek, and rice husk to remove contaminants. This system targets microplastics and PFAS, often called forever chemicals. Independent laboratory testing showed significant removal efficiency for these pollutants. The affordable and eco-friendly prototype aims to make safe drinking water more accessible.
