Many great scientists developed their curiosity for science at an early age and in January we called on the brightest young minds from around the world to send us their ideas to change the world. Our 2013 Google Science Fair attracted an exciting and diverse range of entries, with thousands of submissions from more than 120 countries.

After a busy few months for the judges, we’re ready to reveal our 90 regional finalists for the 2013 Google Science Fair. It was no easy task selecting these projects, but in the end their creativity, scientific merit and global relevance shined through. This year’s finalists projects range from using banana peels to produce bioplastics to research into a green treatment for contaminated water. Other projects include a study on the effects of video gaming on the cognitive function of the brain and the evaluation of wireless transmission of electricity.

The 90 Regional Finalists come from all over the world.

For the second year, we’ll also be recognizing the Scientific American Science in Action Award. This award honors a project that makes a practical difference by addressing an environmental, health or resources challenge. From the 90 finalists’ projects, 15 were nominated for this year’s award.

On June 27 we’ll announce the 15 global finalists and the winner of the Science in Action Award. These young scientists will then be flown to Google’s California headquarters for the last round of judging and a celebratory event on September 23.

Thank you to everyone who submitted a project—we really appreciate all your hard work. Congratulations to our 90 regional finalists!
