Irish Trio Wins Google Science Fair

Three cheers for this lovely teen trio from County Cork, Ireland!

Émer Hickey, Ciara Judge, and Sophie Healy-Thow recently won the Grand Prize in the 15-16 age group of the 2014 Google Science Fair.

To be sure, that’s pretty cool in and of itself, but it’s the particulars of their project that really take this farmgirl’s cake …

Reportedly inspired by Émer’s observations within her family’s backyard garden, the trio set out to study the effects of beneficial bacteria on the growth of cereal grain crops (and to think, we’ve just been picking and eating our veggies all this time).

“Émer and her mom were gardening, and she noticed nodules on one of their pea plants,” Sophie told National Geographic. “She brought that into school, and our teacher told us it was bacteria.”

As it happened, the girls’ class was in the midst of a lesson on the world food crisis, and they learned that the knobby nodules on plant rhizomes hold beneficial bacteria that boost growth. For visual reference, here are “Rhizobia nodules” attached to roots of a cowpea plant:

“We became really interested in what this bacteria can do and what people haven’t done with it so far,” said Sophie.

Atta girl!

People—lots of people—apparently told the girls that the bacteria wouldn’t have an impact on cereal crops, but they shrugged off the naysayers and decided to test their hypothesis on barley.

According to Scientific American, the team has tested the effects of beneficial bacteria on some 13,000 seeds over the course of three years. “We did a lot of experimental work in Ciara’s house,” Émer told RTE radio after their win. “First, we took over the spare room, then expanded into the kitchen, sitting room, conservatory, and the garden … It was quite a lot of work, but it has really been worth it.”

They found (naysayers be darned) that the microbes increased seed germination rates by 50 percent! What’s more, harvest yields increased by as much as 70 percent. The girls currently have a controlled field site planted with 3,600 seeds in their hometown. Émer says that further benefit may be seen in the reduced need for fertilizers and that improved germination speed is of particular interest to farmers in places like Ireland, where seeds can rot in the damp soil before sprouting.

For more details, listen to the girls explain their awe-inspiring research in their own words:

    Fantastic!! The younger generation are our hope for a better and more prosperous future! It is amazing what can happen when you are open to questions and not pre-judging or dismissing the answers!

  2. Cindi Johnson says:

    These girls are amazing! I wish we would see more of these trail-blazing kids in the news. There are a lot of them out there. Maybe showing more stories like this would help the way too many kids out there that have no one in their life to encourage them, show them that they are incredibly smart and inspire their potential. Oh, and that wearing aprons is cool! Did you see it?

    That’s fantastic! Way to go girls!!!

    WOW!!! Way to go!!
