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.

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.

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.
Watch out, Andy Green!
THEY’RE PROBABLY the only cars capable of giving land speed record holder Andy Green sleepless nights. A team of talented schoolkids smashed a land speed record not once, but twice in the same weekend when their rocket-powered model cars achieved, first, 478.1mph, and then 556.28mph.
Led by proud teacher Phil Worsley, the students, members of the young engineers club at Joseph Whitaker School in Rainworth, Nottinghamshire, shredded the existing record of 287mph set in 2011 when they put three model cars through their paces at Rolls-Royce’s test track at nearby Hucknall last weekend.
