"I'm a star!"
If you move as fast as superman you may be able to make yourself invisible, but for the ordinary person it is just not possible. Theories exist though that "prove" it is possible to make yourself invisible. Doctor Jensen Li and Professor John Pendry have written a paper which surmises making invisible paint.
Such material has to be extremely thin, having a structure smaller than the wavelength of visible light. Scientists have already made a small object invisible by cloaking it in a material comprised of tiny structures. If a material can be developed from nano-sized pieces it could be painted on an object and it would "bend" the light away from sight, i.e., the background would be visible.
Such a material has to be made from silica and silicon because variation in interpreting light is necessary. A person viewing a cloaked object would see a mirage of the background. Don't be too hasty though - we are not in the Star Trek world yet. A person would experience only an illusion of the background!

Blaming Rewiring of the Brain for Chronic Pain is Too Simplistic
What a cop out, medical "professionals" are now saying chronic pain is caused by a mixed-up brain. This cannot be the case when you have an open wound and it really hurts. They are saying we should not feel any pain at all. People with leprosy feel no pain and look what damage they do to themselves.
Pain is functional. It stops one using a limb when there is damage to it. Otherwise, it wouldn't heal properly. Most back pain is caused by damage to the spine that cannot be detected with current technology and knowledge.
Those "in the know" are now saying the brain rewires itself when there is an injury so that when the damage is repaired pain still continues. If this is the case then it is very selective. Why doesn't this happen when you cut your finger? We know if a limb is lost pain can continue, but saying the brain rewires itself after an injury is far too simplistic.

New Anti-Melanoma Treatment Is Promising
Australia has the highest rate of melanoma in the world. People will not listen. Many still regularly tan themselves in the sun or even go to solariums. Any improvement in treating melanoma is sorely needed in this country.
Tumors put up defences against drugs that aim to destroy them. Combining drugs can break down these barriers. A new kind of anti-melanoma drug, the BRAF inhibitor, has been developed. It is not a "golden bullet". Life expectancy can be increased from 8 months to 15 months.
Better results have been obtained by combining BRAF with another inhibitor called MEK. They slow down the growth of the cancer. Some tumor were shrunk. Though the tests were done on only 24 patients, improvement in treatment is promising.

Worry Over Job Security Increases With Casual Work
Gone are the days of local business monopolies where shops, for example, had a higher profit margin so they could keep employees in secure employment for decades. In the past shopping centers didn't exist and a firm had a local licence. Only one type of business could operate in a regional center. If a shop had the fish licence and decided to sell only fish, no fish and chips, you as a customers had to go without a quick hot meal.
The proportion of casual workers is increasing every year. Just how these employees manage to build up capital for retirement is anyone's guess. Holiday pay is said to be built into casual rates, but this is a myth. Such workers hardly ever take a day off because they will not get any pay.
People worry more over job security than anything else. Despite all the troubles in the world, Macquarie University found employees experience more anxiety over losing their jobs than any other issue. This affects men more than women. Seventy per cent of men worry compared to 60 per cent of women. Young people suffered most: eighty per cent were concerned.

"It's elementary my dear Watson."Magnets Stop Crocodiles Returning to Their Home Range
We have been told that magnets have wonderful powers: not only can they be used to generate electricity, they can be used to reduce pain, etc. Now a new use has been found: crocodiles have been fitted with magnets to stop them returning to their home area.
In Florida they have been carrying out an experiment to find out if magnets can be used to disrupt crocodiles' homing ability. Though small in number, crocodiles do cause problems when they wander into populated areas. People fear them even though they are are small and usually run away from humans. In contrast alligators are larger and more dangerous.
Once a "rogue" crocodile has been caught it is relocated to an area free of humans. Magnets are put on the crocodile's head. This affects the animals natural homing abilities so that it remains where it is placed. The population has increased because fewer wander onto roads. This is a good thing as the species is endangered.

Higher Rates of Birth Defects With "Injected" ICSI Babies
For many years we have heard nothing but good things about test tube babies, how they are strong and grow faster, etc. Maybe the "authorities" are telling us what we want to hear, with women choosing to have children later in life.
Older women having babies had their age taken into account when measuring birth defects. If they smoked this was also given a mathematical allowance. This could be distorting the true picture.
There has been a change in the way the "art" of test tube babies is done. Today, an individual sperm is injected into an egg. In the normal fertilization process only the fastest, healthiest sperm is successful.
Evaluation of babies shows that birth defects occur in "injected" babies at a rate of 10 per cent. This compares to 6 per cent for naturally conceived babies. Couples who choose the older form of freezing embryos had normal rates of healthy babies. The attempt to get more embryos by injecting sperm, ICSI, seems to have backfired.

Islander Blondes Are Natural
All black people have black hair - right? This is an incorrect assumption. When Europeans first arrived in Australia they found some blonde Aboriginals. They thought that White sailors must have been shipwrecked off the coast and took Aboriginal wives.
In the Solomon Island near northern Australia 10 per cent of black people have blonde hair. The sun has not bleached the hair white. European sailors are not responsible either. It is a random gene that causes it. This is proven as the tone of blonde is different from Europeans.
A group of Islanders were tested for gene structure: forty two with dark hair and 43 'blondes'. The pigmentation gene was either coded with a "c" which produced blond haired people or 'T' giving dark hair. It is a recessive gene which means both parents must have the blond gene to have a blond child.

Your Shoes Give You Away
Shoes apparently show your inner feelings. When Kylie Minogue wore those extremely high shoe-boots she was saying "I want Attention." She also shows that she is loaded with money, having the shoes specially made, and is waited on hand and foot.
Victoria Beckham is another one who wears shoes that make a statement. Her shoes say I wear these silly shoes everywhere, even to breakfast, because I can.
Mary-Kate Olsen should be careful though about her choice of shoes - wearing bondage gladiator shoes says she likes her sex to be rough.
These woman choose their shoes for particular reasons of course. They really don't feel this way. They are just playing games with those who look at them.

The Science of Carrying a Mug of Coffee
You wouldn't think that finding out how to carry a mug of coffee without spilling it would be a subject for analysis by scientists, but you would be wrong. Rouslan Krechnetnikov took it upon himself to solve this disruptive daily issue.
This area of study dawned upon him when he watched people struggling with mugs of coffee at a fluid dynamics conference. He thought that the solution wasn't simple. It was a complex scientific problem. The coffee carriers gender, age and health would affect the solution.
Tests included walking in a straight line with coffee in hand while looking at the mug or looking ahead. A sensor in the mug measured spillage of coffee. Conclusions were that one should walk slower and, wait for it - watch the mug not where you are going.
This sounds like advice leading one to disaster. "Watch your heads and laps everybody someone's coming who doesn't know where he's going! Why don't you get a cup you fool?"
