Although women make up nearly half of the world population, their presence in the sciences constitutes a vastly smaller percentage. Today, only twelve percent of engineers are female. Science, technology, engineering, and math (STEM for short) are all fields in which women are under-represented. This is precisely why this year’s Google Science Fair results are so exciting–all three top prizes were awarded to women.

The winning projects put the classic baking soda volcano to shame. Lauren Hodge, winner of the 13-14 age group, tested a variety of marinades and their effects on the carcinogens typically found in grilled chicken. Her findings showed that lemon juice and brown sugar sharply decreased carcinogen levels, while soy sauce actually increased them.

Naomi Shah, winner of the 15-16 age group, performed a study of 103 adult subjects where she was able to link the increase in two environmental pollutants to decreased lung function and asthma symptoms.

The grand prize was awarded to the winner of the 17-18 age group, Shree Bose of Fort Worth, Texas. Bose’s project focused on the chemotherapy drug cisplatin that is commonly taken by women with ovarian cancer. Bose discovered a protein known as AMPK that, when paired with the drug, stops cancer cells from becoming resistant to its effects. Bose shared her feelings in an interview with ABC:

“That perception that women can’t compete in science has been ingrained in this field for so long. It just shows that our world is changing and women are stepping forward in science, and I’m excited to be a small part of that.”

This year the fair received 7,000 entries from 91 countries. Despite the notion that the US is falling behind in the sciences, 60% of these entries were from Americans, and all three winners are citizens of the US.

Google scientist and fair judge Vinton Cerf told the New York Times that, “a common thread among the finalists was that they had explored science enthusiastically for years with the encouragement of their parents.”

As part of their awards, the winners received internships at Google, Lego, and CERN, ensuring them a good start to what will surely be successful careers in science.
