Power corrupts

Today's 4corners on Australian ABC is about a former Federal Court Judge Marcus Einfeld who were sent to jail because of lying about a $77 speeding ticket. It seems that Marcus had a habit of lying about the drivers of his car when caught in traffic infringements.

It is amazing to contemplate how people, a judge in this case, would lie and thus committed crimes just to get out of some relatively small matter. I have met a number of nice people who changed into very nasty selfish person when put in a position of power. What corrupts people? Power? Position?

Whatever the reason, checks and balances must be in place to ensure a fair society.

Burning Mercury Thiocyanide

Mercury(II) thiocyanate (Hg(SCN)2) is a chemical compound. It was formerly used in pyrotechnics for the long snake-like ash Pharaoh's serpent that forms when a pellet of this compound, often with a small amount of a sugar such as glucose added to serve as supplemental fuel, is ignited. This is extremely dangerous because it produces poisonous mercury vapors. [source]

Monkey Walking Upright

Although the following video is making round in blogsphere recently, it is in fact an old news[2004]: A monkey at the Jerusalem Zoo has been walking upright after recovering from a stomach flu that nearly killed her [see also]:

Back in 2001:

Monkeys walking on two feet have long been an integral part of circus acts. The way they waddle from side to side appeals to our sense of comedy.
Now, however, Prof. Shigemi Mori and other researchers at the National Institute for Physiological Sciences have succeeded in training monkeys to walk erect smoothly, as humans do, by working with them from the age of 2 1/2 years.
Through this research, the scientists have learned that there is a considerable difference in brain function when an animal walks bipedally and when it walks on all fours. [source]
