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.

Did you know that the particles in a sneeze travel at 100 miles per hour? Find out more fun facts about sneezing.
Why do we sneeze? The long-standing answer has been that sneezing is a reflex. When irritants — such as germs, dust, pollen, animal dander, or pollutants, just to name just a few — infiltrate the nose lining, the brain sends out a signal to get rid of it. That triggers a deep breath, which gets held in the lungs. As a result, the chest muscles tighten and pressure builds. The tongue pushes against the roof of the mouth, forcing breath to come out fast through the nose — Achoo!
