This week we amuse ourselves with the science of laughter. We find out why laughter is so contagious as well as find out how award-winning comedienne Katherine Ryan felt having her genome profiled. We also speak to L'oreal-UNESCO Women in science award winner Tebello Nyokong about her research in finding a treatment for cancer and we go googling for Question of the Week.
