On our monthly Feature Scientist, we talk to Vivey Phasha, a product development technician at CSIR (The Council for Scientific and Industrial Research) on the science behind beauty and cosmetic products. In our science news we discover a polymer coating that can make buildings cooler and the benefits of making kind decisions. In Unscience, we discover that smiling doesn't necessarily mean you're happy. Later on, Vivey Pasha takes us through a journey of her personal life. wits.journalism.co.za
