Are we human? Or are we microbe?

Microbes. EEK!!!

We spend a lot of time and money on antibacterial products. But despite our desperate scrubbing, we will never be free of microbes.

microbes1

In fact, our bodies’ microbial cells outnumber our human cells 10 to one! Which makes you wonder: If you have more microbial cells than human cells, are you human?

Of course! Humans play host to microscopic microbes, collectively known as the gut microbiome, that reside in the small and large intestine.

These microbial symbionts perform vital functions, especially during digestion.

microbes2
Many of these genes encode enzymes that digest food, such as CAZymes, which break carbohydrates into compounds that the body can absorb or excrete.
microbes3
If the composition of the gut microbiome changes, the body may lose the ability to perform certain functions, which could result in inflammatory bowel disease (IBD).

Even from the deep regions of our intestines, our gut occupants can influence much more than our bowel health.

microbes4
Studies report colonization of certain species of bacteria is more likely to be associated with depression and anxiety. Many researchers believe adjusting the composition of the gut microbiome may be a viable treatment for these disorders.

We may be human, but we are run by microbes, no matter how many times we wash our hands.

Announcing Buzz Hoot Roar’s new Artist in Residence!

We at Buzz Hoot Roar are pleased and proud to announce our newest Artist in Residence! Over the next year, Christin Hardy will use her unique graphic style to explore six science posts. Read on to learn more about Christin, and stay tuned to enjoy her excellent work.

Christin2

Who: I’m Christin Hardy, a graphic designer and illustrator living in the city of oaks, Raleigh N.C., and hailing from Seven Springs, a teeny tiny town in rural Eastern North Carolina where the livestock outnumber people.

Christin1

I graduated from NC State University with my bachelor’s in graphic design, and after a few odd jobs landed my current job as a graphic designer for the NC Department of Transportation. There, I get to work on projects from all sorts of divisions ranging from aviation and rail to highways and bike/pedestrian. One of my favorite projects was the poster I made for National Train Day in 2014:

Christin6

Why: I’ve always loved science and tend to choose extracurricular activities that reflect that, such as volunteering for the Duke Lemur Center (so much fun), working for the entomology lab at NCSU where I counted bee sperm for a summer (not as fun, but cool) and interning at the Smithsonian in Washington D.C. (definitely ties with the lemurs).

So, when I got the email asking if I wanted to be the next artist in residence, I immediately gasped and said “YES!! Of course!!!” While I enjoy my work for the government, Buzz Hoot Roar gives me an outlet where I can […]
