THE SCIENCE INSIDE - Pollution

This week, we chat with Nano technologist Florence Lehutso, from the Council for Scientific and Industrial Research (CSIR), as she delivers her teams’ findings on nano-pollution and the extent of pollution on our water sources if not evaluated and studied extensively.

In our final story, Wouter Le Roux from the CSIR unloads the results of his study where he discovered that water sourced from hand-dug wells in the community of Stinkwater is contaminated and unsafe to drink.

Lastly, on unscience, we find out how high-level mathematicians are tricked by some aspects of their knowledge about the world and as a result fail to solve primary school-level subtraction problems.
