David Cohen understands that mosquitoes aren’t just pesky annoyances — they’re global killers, too.

That’s why the 12-year-old from Dallas invented a robot that drowns the pests using a pump-jet system that traps them underwater using mesh. He submitted his work to the Discovery Education 3M Young Scientist Challenge earlier this year and is one of the competition’s ten finalists.

The challenge, which is open for students who are in grades 5 through 8 at the time of submission, awards its winner $25,000, the title of “America’s Top Young Scientist,” and an all-expenses paid vacation. A victor will be decided after finalists present their work on Oct. 13 and 14 in St. Paul, Minnesota.

Did you know that only one in ten of the cells in your body is actually human? That’s right. A whopping 90 percent of your cells are bacterial, viral, or parasitic in nature.

The NIH’s Human Microbiome Project is ambitiously aiming to characterize the microbial communities living in us. And while the vast majority of these germs are symbionts, once in a while, we pick up a straggling critter that’s not just along for the ride–it’s there to leach our nutrients at all costs.

These parasites fall in five distinct categories, the first of which is the most numerically abundant animal on Earth: nematodes.
