Did humans lose their sixth sense?

Humans are said to be the most advanced beings on the earth.There may be unknown beings outside the earth who are more advanced technologically or socially “aliens” but then on earth “homo sapiens” rule.
We have heard of people having halucinations, dreams probing into the future, of some instances or events that have never taken place, people talking to spirits,or people even talking to an unknown entity called “GOD”.
In a recent fiasco called “Tsunami” more than 150,000 people died because of nature's ferocious and demonic behaviour and we lost our precious submarine point too, but surprisingly not more than 2 water buffaloes and a few sea rodents have been found dead.
Does this mean that aninals have a better sense of nature than humans?
On a day before the event occurred and the morning at sunsrise, elephants were seen running to higher ground and flamingoes leaving their lower nests and moving to higher grounds.
Dogs refused to go out of their shelters.
This shows that they seem detect the tremors of earth;s gurgoil many hours before the event even occurs.
If this is called the sixth sense then why don't humans possess it though we are more advanced than aninals?
Scientists say that our ancestors might have had a sixth sense like our five senses of sight, sound, touch, taste, smell.Our distant ancestors may have had a sixth sense that modern humans have lost because of a genetic mutation.
Some researchers believe that the vestige of an organ that we all have in our noses was once responsible for detecting chemical signals given off by other humans. Some even think that it still influences our behaviour.
Located just behind our nostrils are two tiny pits called the vomeronasal organ (VNO). The organ contains nerves that respond to chemicals called pheromones that are secreted by many animals. Whether humans do so as well is a matter of conjecture.

Mouse gene
Professor Catherine Dulac of the Harvard Medical School and researchers have isolated in mice a gene that she believes plays a major role in the detection of pheromones.
Professor Dulac believes that Pheromones may play an as yet unappreciated role in human behaviour. Humans have the gene as well but in a mutated form that may make it useless for detecting pheromones. This suggests we may once have had the ability to pick up the delicate chemical language of pheromones but have now lost it because the VNO cannot develop and function properly.
The researchers are currently making a careful search for other human genes that we may use to detect pheromones other than the one we share with mice. Rats and mice have well-developed VNO's containing millions of nerve cells. The human VNO is different - it may work in the same way or it may not.
Pheromones from insects and rodents are known but so far nobody has been able to find one from humans, despite the scent products that can be bought with names like "Desire. "

Ok, Do humans have a sixth sense?

This is a question that every person should ask themselves.

Here is Japanese folk tale to answer this question.
One day a young samurai approached a revered teacher of swordsmanship and begged acceptance as a student.
"You must do everything I ask you without question." The teacher warned. The samurai agreed without hesitation.
"Hai." Said the teacher "Go to the Dojo and walk along the edge of the Tatami by placing one foot in front of the other."
Perplexed the samurai did as he was told but after a week of this practise, he became impatient to pick up a sword. After the tenth day, he could take no more and angrily questioned the teacher when they would begin serious training.
"Very well." Said the teacher. "Tonight we will begin serious training."
That night under a full moon, the teacher took the Samurai up into the mountains until they came to a deep and narrow gorge. Spanning the gorge was a fallen tree.
"Here we begin training." Said the teacher. "Cross over the gorge."
"But the tree is too narrow." Said the samurai.
"It is much wider than the edge of a Tatami." Replied the teacher.
The Samurai jumped up on the fallen tree but as he began to step forward the dim moonlight and the sound of rushing water beneath him seemed to pull him off balance.
"I cannot cross." Said the Samurai.
"Well then, how can you expect to master the sword when haven't yet mastered walking?" Said the teacher.
At first glance, the above tale, like many such `teaching tales’ from the Far East, illustrates a simple lesson in humility. However, a deeper meaning to the story is revealed when you ask the question, why couldn’t the Samurai cross the gorge? The answer is that the Samurai hadn’t mastered his sixth sense.
Before modern medicine, man generally recognized that he had five senses, sight sound, touch, taste and smell. The so-called sixth sense was thought to be an extra sense hence the term Extra Sensory Perception or ESP. It is now known that we have three other senses, balance, proprioception, and a sense of direction. Anything paranormal would have to be moved down the list to the `ninth sense’.
The story indeed teaches a lesson about the sixth sense, balance. The ability to master one’s senses and control perception is an important skill underlying every other. In the case of the Samurai and the gorge, it was his inability to master his perception of balance that prevented him from crossing.

Nano Technology




Nano technology

we have seen sci fi movies where we see plateles and red blood corpuscles rushing up and down with the hero and the heroine!
Is it possible in reality today?
Yes ,amazing to hear isn't it!
No doubt about it.
Instead of the hero and the heroine we can have miniature robots rushing your blood stream!
They can do amazing work like mending your skin or wounds or making a new organ for you when you are asleep.
Doesn't it sound crazy?
But today man has the ability to create and use such docile robots which help instead of waging a war against as shown in the movie “Terminator “.
How is this amazing feat of human advancement achievable?
It was once stated in 1959 by Richard P Feyman that we would create robots that would in turn create arms 1/10th of its size which would inturn create arms 1/10th of their size and so on.
This is called nano technology i.e building miniature robots which can be used and controlled to build objects at molecular level.
It is also building objects and products bottom up,other than our conventional top down methodology used for product assembling and building.
The science of tiny molecules, is a magnificient achievement in human history, a very important aspect for modern life. The fields like biotechnology, electronics, energy and industrial products are using it a lot.
Nanotechnology is also about using the technology to use particles of that size for administering medicines too.
The recent noticable applications are in wind shields for protecting from UV rays and in dirt resistent clothes.
In a recent Hindu article an exibition was shown.
Many glass boxes were placed with big gizzmo lenses to see through the exhibited objects.
A nano guitar, nano car, nano bikes, nano planes, nano eiffel tower were a few among the 121 participants in the exhibition.
Here are some of the pictures that were shown in the exhibition.



Nano copper particles Nano sphere Nano zinc particles
Also the latest improvements are molecules washing dirt off clothes, robots repairing Integrated circuits, molecules destroying cancerous and bacterial cells.
But look at the dark side where there are many places where this can be misused.
What happens if the nano particles cross into in intended boundaries of cells and interfere with other metabolic activities?
When you talk at nano level even the elements like gold and platinum become reactive.
So what happens if a person sends a spray into our gold reserve and all are converted to nothing in seconds?
We should have some ethics listed and grounded at that level too to use such effective and sharp technologies in day to day life, so that the dark side of humanity dont miss use it.
In future, probably in a couple of decades like when we are in our mid forties, we would be using millions of such robots and particles which would live inside our body with us eat and drink with us and help us to live a very long life!
But Beware ! Even a mice scares an elephant away!
