Elephants ATTACK!

Asian elephants kill, on average, nearly 400 people across India each year.1, 2

Migrating around Asia, they scarf down and stomp on people’s crops, smash their homes, and drink their liquor.

bHR_01

In all, elephants snarfle down the crops of at least 500,000 families in India each year (each elephant eats about 440 pounds of vegetation per day).1

rascoe_no_number_03

The big meanies.

Except . . .

People kill elephants right on back. In addition to the more than 100 Asian elephant retaliatory killings each year, at least

bHR_07_03

 

 

are electrocuted on fences,

 

 

bHR_07_07

 

 

die from diseases like anthrax and trypanosomiasis they contract from human-owned cattle, and at least

 

 

bHR_07_05

 

 

are killed by trains (over 100 total elephants have died from trains). 2

 

Nobody knows how many more elephants die from getting trapped in human-dug drainage ditches, poaching, direct habitat loss, and more, so let’s not count those.

So . . .

Taking the largest estimate of total Asian elephant population today3 and the CIA’s estimate of the total population of Bhutan4 and India5, let’s compare the damage.

Elephants are 12,422 times more likely to die at the hands of humans than humans are to die from elephant-related causes.

bHR_17

And while humans have encroached on 80 percent of elephant-inhabited forests, elephants have damaged less than one millionth of one percent of Indian farmland. bHR_15

 

Maybe we’re the jerks.

Or maybe it’s a complicated problem. One that we can help fix.

How Many Does It Take?

Here at Buzz Hoot Roar, we love how humans measure everything and hand out superlatives. Today, we see how many of the biggest, longest, or tallest animals in their class (or order or family!) it would take stacked end-to-end to reach the top of some of our favorite landmarks. (It’s probably pretty important to know how many of the largest known bacteria it would take to reach the top of the Eiffel Tower.)

How many of the tallest dinosaur versus the biggest bacteria does it take to reach the top of the Eiffel Tower?

…and how many of the longest jellyfish versus the longest tapeworm does it take to stretch to the top of the Grand Canyon?

What’s the difference?

When it comes to some animals, it can be hard to say at first glance exactly what makes one group different from another. Besides, someone always breaks the rules (We’re talking to YOU, Mrs. Macaque!). That said, here’s a quick-and-easy guide to help you tell the general differences between some often-confused animal doppelgangers.

What’s the difference between . . .

a frog and a toad?

an ape and a monkey?

a turtle and a tortoise?

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.

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.

Frogs in Pants Finally Explain Sex

For centuries, people believed that maggots and fungi magically sprung from inanimate objects out of thin air. Spontaneous generation! How babies happened was also shrouded in myth, and by the mid-1600s, people had yet to figure out that, in humans, barely visible eggs and microscopic sperm were part of the process. Turns out, all it took was a pair of frog pants to get the ball rolling in the right direction.

A happy day for science: frogs in pants, the first empirical demonstration of barrier contraception, and spontaneous generation went the way of the powdered wig.

Squirrel Chat: No Longer an Elitist Pastime

Eastern gray squirrels can live up to 12 years in the wild, so why not befriend your favorite little nut stasher? Yes, it may be intimidating at first. With their luxurious tails and constant incoherent chatter, hanging out with squirrels can seem like hanging out with a bunch of drunk debutantes. Lucky for us, in 1959 a guy named Arnold Bakken decoded their language1 so we can finally have a meaningful conversation with them (or at least get the treetop gossip).

Yaaaaaaaawn!

Chasmology! The study of yawning! It’s a real thing! There’s even an international conference!

Everybody yawns!

yawn1_03

Even human fetuses!

yawn2_02

Seeing, reading, or thinking about yawning triggers more yawning in humans (except those of us with schizotypal personality traits). Contagious yawning happens more often when you’re warm and when you breathe through your mouth and most probably is a primal, uncontrollable expression of human empathy.

Untitled-1_03

So it’s no surprise that children don’t yawn contagiously until they’re a few years old.

yawn4-mine_03

If you’re out with your Romeo or Juliette and they start to yawn, don’t fret! In people, yawning is triggered by some sex-related agents like oxytocin and androgen, and many males get sexually aroused when they yawn.

yawn5_03

And one more thing, to set the record straight: Research shows we DO yawn when we’re bored, we DO yawn because we’re sleepy, and we do NOT yawn because of high CO2 levels or low O2 levels in the blood and brain.
