Meet the 'Stars of Science' for season 7

The decision has been made and the 12 candidates to compete on the seventh season of " Stars of Science " have been revealed. Over the course of the season, these ambitious inventors will work alongside mentors in Doha to refine their ideas and build prototypes of their inventions.

Contestants will be tested in elimination episodes, during which the judges evaluate their engineering skills. Four finalists who survive the elimination rounds earn a share of the $600,000 prize, with the winner being revealed in a special live finale.

Last month, representatives of the program said this season would feature "its most talented innovators to date." Here is a look at the 12 individuals competing to the be the Middle East and North Africa's new "Star of Science."

From: Lebanon

Project: Ergonomic Activity Desk Lamp

The lamp analyzes a range of factors to ensure the ideal lighting conditions for tasks such as reading, writing, soldering and tailoring. As the user changes activities, the light changes seamlessly. The product would help students, office workers, mechanics and others professionals avoid the negative effects of bad lighting.

From: Jordan

Project: Date Pits Filter in Desalination

Ayesh's environmentally conscious project uses crushed date pits to rid seawater of its salt, making it drinkable. The project is significant for the region and globally, as freshwater sources are being depleted while the population continues to climb.
