"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.

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"

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.

Our history with helium is a lesson in the consequences when governments fail to properly manage a finite natural resource.

Fear not balloon lovers. Here is how to make a balloon full of hydrogen at home. You will need a fairly large glass bottle (a litre or larger) with a small spout that you can fit the balloon onto. Add about a cup of water then dissolve in maybe four tablespoons of household lye. To this add a square foot or so of aluminum foil. The foil acts as a catalyst and produces an extremely exothermic reaction. The solution actually will begin to boil. THIS IS VERY DANGEROUS due to the heat and the caustic nature of lye.

Pop a balloon onto the spout and it will fill with hydrogen produced by the reaction. When full, pull the balloon off by squeezing its neck, knot it, tie a thread to it and up she goes.

For an added thrill, light the bottom of the thread. It burns upwards and ignites the balloon. Hydrogen burns at a low temperature. I have done this over 50 times over the years with zero bad consequences and the sound is very loud and will scare the bejesus out of everybody.

Eventually the reaction runs its course in a few minutes.
