Hey, Chart Geeks!
Kelly and Zach Weinersmith here, and we’re today’s Chartists in Residence! Zach does a comic called Saturday Morning Breakfast Cereal
, co-creates SMBC Theater
, does a blog on math, science, and other things at TheWeinerworks
, and has two books out through Breadpig
. Kelly is a PhD student at the University of California Davis, where she studies brain infecting parasites and their effects on behavior. We both do a geeky science podcast called The Weekly Weinersmith
Zach will be bringing you dirty jokes in graph form, and I will be bringing you science graphs (mostly about parasites!)
In Western countries, the percent of its citizens that are infected by the brain-infecting parasite Toxoplasma gondii
correlates with how much people find uncertainty to be frightening. These countries tend to adhere to rules, as rules tend to make people more certain of things that will happen in their environment. Is a brain-infecting parasite influencing human culture? Click here

Sources of Stress
Beer gets mosquitos all hot and bothered. When exposed to the smell of someone who has drank a beer, mosquitos move around more (“Activation”), and is attracted to that person’s scent (“Orientation”). This doesn’t happen after you drink water. Click here

The bacteria living in your gut may influence your personality. The top row of the graph tracks the movement of a mouse with normal gut bacteria (“SPF” means “specific pathogen free”) as it scurries around in an open arena over the course of an hour. The bottom row tracks the movement of a mouse that grew up without gut bacteria (“GF” means “germ free”). This little dude is much more active towards the end of the hour.

What’re the odds?
Some penguins are able to expel their poop with such great pressure that it lands far away from their nest, thus keeping their homes tidy. Scientists calculated the pressure that penguins would need to send their poop flying a given distance, and this chart outlines the parameters they used in their model.

In fruit bats, fellatio extends male sexual stamina. Complete with illustration. SCIENCE.
Strippers on the pill make less money in tips than do their non-pill using counterparts. This is especially apparent during the most fertile period of the women’s cycle. More.

Thanks for a great time! We’ve laughed, we’ve cried, we’ve fellated bats.
My dad always said, “Leave a campsite in better condition than when you first encountered it.” You’re welcome, Jason.
