Hoot’s Adventures with Emu Poop

Speaking of poop, while wandering the Australian Kwongan sandplains, Hoot and his companion noticed not all emu poop was created equal1. It turns out that emus are pretty good at helping seeds spread around by scarfing down fruits and plant material and plopping out fertilized seed cakes all over the land2. Check out Hoot’s emu poop glamour shots and marvel at those long-legged seed dispersing machines, emus.

Poop Transplants

For the estimated 3 percent of people who have Clostridium difficile bacteria living in their guts, it’s usually no big deal. C. diff. just sort of hang out, kept in check by all their other bacteria gut-mates.

01_Atteberry

But sometimes the balance of power gets messed up. Whether it’s because of old age, illness, or antibiotics, those “good” bacteria get killed off, and C. diff begins taking over—leading to diarrhea, fever, and even death.

02_Atteberry

Traditional antibiotics often don’t work against C. diff. But know what does work? Poop transplants.03_Atteberry

Putting someone else’s poop in one’s body brings in reinforcements for the good bacteria, which whip C. diff back under control. (And the transplant is administered through a tube in your nose. Really!)

04_Atteberry

How well do these transfers work? In one study, 15 out of 16 patients who got a poop transplant recovered from their C. diff symptoms—while only four out of 13 patients on antibiotics got over their C. diff symptoms.

05_Atteberry

Want to avoid getting C. diff? Wash your hands. It makes it less likely that C. diff spores will hitch a ride into your mouth (and later—to your gut).

Editor’s note:

While we commend these brave creatures on their orbital journeys and appreciate the valuable job they do for us humans, we’d like to point out that many other animals went into space before and after them. Animals like monkeys, apes, dogs, mice, cats, goldfish, and chimpanzees. Some returned fine, and others suffered extreme conditions. Outer space is littered with the corpses of more than half a century of our investigations. Here’s a brief summary of some of our unfortunate animals: http://science.howstuffworks.com/dead-animals-in-space.htm, and you can read more about them online.

For Love or Supper: Why Critters Light Up

Breaking news: Hundreds of underwater species radiate neon greens, reds and oranges as they shimmy through the ocean’s depths.1 But sea creatures aren’t the only animals at ease in the limelight. Buzz Hoot Roar guest-author Matt Shipman offers a few good reasons why sea and land animals put on the ultimate light show.

Gluteal Crease: Where the Butt Crack Begins

Gluteal crease! The top part of your butt crack!

buttcrack1

A great place to live, if you’re bacteria. Thanks to your g.c.’s warm, “moist” environment, a bouquet of biota feels right at home. Humidity-loving microbes like Staphylococcus and Corynebacteria  delight in hanging out in there (and other warm, moist areas like inside your belly button and in your toe cracks).

buttcrack2

 

There, they scarf down your sweat, and in the process generate what scientists call “butt funk.”1,2

buttcrack3

As an aside, plastic surgeons want you to know the “most attractive” gluteal crease is a v-shaped one.3 In case you were looking for something else to dress up.
