What makes us tick?
It seems some of the answers will be found this week in the most unlikely of places - a science music competition.
Young scientists from around the country are being encouraged to enter Science Idol with rap, pop, or punk songs about what makes us tick.
Award-winning Stanford University biologist and science rapper Tom McFadden has been working with primary and intermediate schools in New Zealand, to get them to turn science into song.
Mr McFadden, also known as the Rhymebosome, has quite a reputation for sharing complicated scientific theory with science pupils by rapping about things like DNA, electrons or how glucose is converted into energy or ATP through glycolysis and the Krebs cycle.
Science Idol entrants were required to create a 30-second to two-minute-long music video on what makes us tick.
Entries closed on Sunday.
Winners will be announced on Friday and the grand prizewinner wins a trip to Dunedin to have their music professionally recorded at the University of Otago's Albany St recording studio.
The winners will also perform live with Mr McFadden during the New Zealand International Science Festival on July 6.
