Scientists gain insight into invisibility
through a complex superlens

The Klingons used it to make their Bird of Prey spacecraft invisible. The Romulans used cloaking too and variants of this stealth technology hid the nasty alien in the Predator films and have been mentioned in Star Wars, Doctor Who and more besides.
Prof Graeme Milton, of the University of Utah, and Nicolae-Alexandru Nicorovici, of the University of Technology, Sydney, announce that "we have found that cloaking might be realised". The "making of an object invisible through some cloaking device is commonly regarded as science fiction", said Prof Milton.
But with Dr Nicorovici he outlines how to do it with the help of materials with bizarre optical properties that were first postulated in 1968 by Victor Veselago, a physicist working at the General Physics Institute of the Russian Academy of Sciences in Moscow.
When an object is bathed in light of one colour, Prof Milton and Dr Nicorovici predict that light becomes trapped near the lens and "almost exactly cancels the light incident on each molecule in the object, so it has essentially no response to the incident light. Numerically we see that the molecule is effectively invisible".

Hey Byron, Found this and thought you might like it. Bob
BUDAPEST (Reuters) - Hungarian builders who drank their way to the bottom of a huge barrel of rum while renovating a house got a nasty surprise when a pickled corpse tumbled out of the empty barrel, a police magazine website reported.
According to online magazine www.zsaru.hu, workers in Szeged in the south of Hungary tried to move the barrel after they had drained it, only to find it was surprisingly heavy and were shocked when the body of a naked man fell out.

The website said that the body of the man had been shipped back from Jamaica 20 years ago by his wife in the barrel of rum in order to avoid the cost and paperwork of an official return.

According to the website, workers said the rum in the 300-liter barrel had a "special taste" so they even decanted a few bottles of the liquor to take home.

The wife has since died and the man was buried in a proper grave.

OMG - that is unbelievable! And to think dark rum was one of my favourite drinks a few years ago - think I'll stick to water now!
