The Young Engineers and Scientists of Africa (YESA) is an initiative aimed at increasing the pipeline Science, Technology, Engineering, Mathematics and Innovation (STEMI). YESA interventions operate from Grades 0-12 and are designed to supplement the national curriculum in a stimulating and challenging environment to promote creativity and innovation. All interventions are aimed at addressing the gaps in the developmental stages of providing support to learners through a broad range of activities.
Rosetta is named after the Rosetta Stone, an incomplete stela of black basalt incised with the same priestly decree in three scripts (Egyptian Hieroglyphs, Egyptian Demotic and Greek) concerning Ptolemy V. The great significance of the Stone is that it provided the key to deciphering Egyptian hieroglyphs. The Rosetta Space Mission seeks to see if comet C-G can provide a key to deciphering the origins of the solar system and/or life on Earth.

Nearly one billion people around the globe are homeless or live in substandard housing. In the era of 3D printing, some have addressed this crisis through quickly built concrete buildings. While this method would create a secure dwelling, delivering the raw materials and bulky printer increases the cost significantly, reducing its feasibility. The Italian 3D printing company WASP may have solved this problem by developing an easily-transportable machine that can quickly create dwellings out of mud and natural fibers—materials already available where the houses will be built.

It’s been nearly 30 years since the catastrophe at Chernobyl, and as the cleanup grinds on, the far-reaching effects continue to be documented. Birds with smaller brains, increasing spiders, decreasing butterflies, all these and more have been reported from the areas surrounding Chernobyl. One group you don’t hear very much about are the decomposers -- those bugs, microbes, fungi, and slime molds who nourish themselves by consuming the remains of dead organisms. Without these recyclers, carbon, nitrogen, and other elements essential to life would be locked in plant corpses.
