Hans de los Santos, 16, of the United States, was the overall top scorer in the Popular Vote contest with more than 8,000 likes for his video “The Power of Antimatter”. As a result, Hans will receive automatic entry into the final round of judging that determines the winner of the Breakthrough Junior Challenge.

The winner of the Breakthrough Junior Challenge will be awarded a $250,000 college scholarship. The science teacher who inspired the winning student will also win a $50,000 prize and the winner’s school will receive a state-of-the-art science lab valued at $100,000.

Additionally, Popular Vote Regional Champions were named for each of the seven geographic regions. They are:

  • Jasmine Eyal, 15, Czech Republic (Europe)
  • Sia Godika, 17, India (India)
  • Cheng-You Ho, 16, Taiwan (Asia)
  • Brandon Kwok, 16, Australia (Australia / New Zealand)
  • Jeffrin Mario, 17, United Arab Emirates (Middle East / Africa)
  • Rupali Mishra, 17, Brazil, (Central / South America)
  • Hans de los Santos, 16, United States (North America)

The Popular Vote contest ran from September 5 to September 20 on the Breakthrough Prize Facebook and YouTube pages, and invited the public to vote for their favorite semifinalists by “liking” the videos. Collectively, during the 16-day contest, the 30 videos reached more than 500,000 people, helping to teach and inspire minds across the globe.

This year the Breakthrough Junior Challenge attracted more than 2,400 applicants. Since its launch in 2015, the Challenge has received 25,000 submissions from more than 200 countries. Submissions were narrowed down to 30 semifinalists, which represented the top submissions after two rounds of judging: first, a mandatory peer review, followed by an evaluation panel of judges.

Past Breakthrough Junior Challenge winners have hailed from Canada, India, Mauritius, Peru, the Philippines, Singapore, and the United States.

The finalist videos will be reviewed by the Selection Committee, comprising of: Ian Agol, professor of mathematics, University of California, Berkeley, and Breakthrough Prize in Mathematics laureate; Rachel Crane, former space and science correspondent, CNN; Pascale Ehrenfreund, PhD, president, Committee on Space Research COSPAR; John Grunsfeld, PhD, NASA astronaut and administrator; Mae Jemison, science literacy expert, former astronaut, and principal, 100 Year Starship; Jeffrey W. Kelly, professor of chemistry, Scripps Research Institute; Scott Kelly, retired NASA astronaut; Salman Khan, founder and CEO, Khan Academy; Ijad Madisch, CEO, co-founder, ResearchGate; Nicole Stott, NASA astronaut; Andrew Strominger, professor of physics, Harvard University; Terence Tao, UCLA professor and Breakthrough Prize in Mathematics laureate; Esther Wojcicki, founder, Palo Alto High Media Arts Center; Pete Worden, chairman, Breakthrough Prize Foundation and executive director, Breakthrough StarShot.

For the ninth year, students ages 13-18 were invited to create original videos (up to two minutes in length) that illustrated a concept or theory in the area of life sciences, physics or mathematics. The submissions were evaluated based on the students’ ability to communicate complex scientific ideas in the most engaging, illuminating and imaginative ways.

The Breakthrough Junior Challenge is a global initiative to develop and demonstrate young people’s knowledge of science and scientific principles; generate excitement in these fields; support STEM career choices; and engage the imagination and interest of the public-at-large in key concepts of fundamental science. Submissions are judged on the student’s ability to communicate complex scientific ideas in engaging, illuminating and imaginative ways.

The Breakthrough Prize

For the 12th year, the Breakthrough Prize, renowned as the “Oscars® of Science,” recognizes the world’s top scientists. Each prize is $3 million and presented in the fields of Life Sciences, Fundamental Physics and Mathematics. In addition, up to three New Horizons in Physics Prizes, up to three New Horizons in Mathematics Prizes and up to three Maryam Mirzakhani New Frontiers Prizes are given out to early-career researchers each year. Laureates attend a gala award ceremony designed to celebrate their achievements and inspire the next generation of scientists.

The Breakthrough Prizes were founded by Sergey Brin, Priscilla Chan and Mark Zuckerberg, Julia and Yuri Milner, and Anne Wojcicki and have been sponsored by foundations established by them. Selection Committees composed of previous Breakthrough Prize laureates in each field choose the winners. Information on the Breakthrough Prize is available at
