Spiders in Australia

Not even rodent scum are safe

So, there's this story going around about a Huntsman fighting a mouse, winning, and then dragging it up on top of a refrigerator for safe keeping and later consumption.

Now, if you're an Aussie, this should come as no surprise to you. Spend more than 30 seconds looking at the glorious profile of +Lerato Majikfaerie​ and you'll see that Australia has some of the best 8-legged wonders on the planet.

According to the bloke whose house this battle took place in, " just letting you all know that the spider is fine. We have named him Hermie, we have adopted him and he is now running his own extermination business out of our town Coppabella. Oh and he is now paying rent"

"This is your chance to....live like a white man"

We've sure come a long way!

The days of the White Australia Policy (https://goo.gl/U25WT2) are long behind us, thankfully. But, are they really? Even a casual glance at the world over the past hundred years will show you that "the Western world" needs a group/minority to hate so that they can feed the war machine. The Germans, Japanese, Italians, Koreans, Vietnamese, Arabs - and many others in between. And I've not even mentioned the -isms.

The fear of the unknown is a very powerful force.

Impact of prion proteins on the nerves revealed for the first time
When prion proteins mutate, they trigger mad cow and Creutzfeldt-Jakob disease. Although they are found in virtually every organism, the function of these proteins remained unclear. Researchers from the University of Zurich and the University Hospital Zurich now demonstrate that prion proteins, coupled with a particular receptor, are responsible for nerve health. The discovery could yield novel treatments for chronic nerve diseases.

What are prions?
Although they start out as harmless brain proteins, when prions become misfolded, they turn into contagious pathogens that recruit any other prions they come into contact with, grouping together in clumps that damage other cells and eventually cause the brain itself to break down.

If that's not bad enough, mutated prions can't easily be killed by heat or radiation, meaning once they've come into contact with something like surgical tools, they can potentially spread to other patients.

In the 1990s, they were responsible for the BSE epidemic more commonly known as mad cow disease. In humans, they cause Creutzfeldt-Jakob disease and other neurological disorders that are fatal and untreatable.

Meanwhile, we know that infectious prions consist of a defectively folded form of a normal prion protein called PrPC located in the neuron membrane. The infectious prions multiply by kidnapping PrPC and converting it into other infectious prions.

But what are the repercussions for the organism if the prion protein is deactivated?
Absent prion proteins cause nerve diseases

This discovery solves a key question that has long puzzled neuroscientists and points towards future applications in hospitals.
