This week we discover a plant indigenous to South Africa that is being used to create stress-relieving drugs worldwide and how more of these native plants could be made use of in the future. We also find out about superior solar cells, how our brains choose which hand we should use and discover a new way to catch drug traffickers in the act! Plus, we investigate if it's possible for a ball to roll uphill, in Question of the Week!
