Amazing and Interesting facts about your Brain and DNA.

Brain and DNA facts

Wondering about how your Brain and DNA works? Don't worry today I am going to explain about Brain and DNA, and how it works.

According to scientists Brain and our Body DNA are the most complex things in our Human body, Below are some facts about our own Brain and DNA.

The modern brain is an energy hog. The organ accounts for about 2 percent of body weight, but it uses about 20 percent of the oxygen in our blood and 25 percent of the glucose (sugars) circulating in our bloodstream.
The foundation for the brain is set early. Three weeks after conception, a sheet of embryonic cells called the neural plate folds and fuses into the neural tube. This tissue will become the central nervous system.
Velocity of signal transmitted through a neuron = 1.2 to 250 miles/hour, Wow! that's more then the speed of a super Racing car.
There are as many neurons in the human brain as stars in the Milky Way. So it is better to count the stars in our galaxy rather than going for the neurons in our brain.
The largest part of the human brain is called the cerebrum. Other important parts include corpus callosum, cerebral cortex, thalamus, cerebellum, hypothalamus, hippocampus and brain stem.
A thought is a physical pathway in the brain. The more you have that thought the more you groove that path and the easier it is to have it again. That's why having the thought "Why do I suck?" is never a great idea.
Your brain has no pain receptors which is why if I managed to remove the top of your skull without you noticing I could poke around all day without you feeling a thing. The skull removal may hurt a bit though.
Until relatively recently scientists thought that the brain was the only area of the human body that didn't generate new cells. We now know that's not true and the brain does reproduce shiny new cells for you to use.
Your brain is constantly lying to you when you have your eyes open. Because it cannot deal with every single detail that you're looking at, the occipital lobe is joining the dots with what it presumes is there.
Similarly, your brain doesn't record memories like video as it would be easy to assume. It takes snapshots of the more important bits and then when you recall the event it guesses what happened in between based on prior experience.
This was some amazing facts about our Brain, Now lets move to DNA.

# DNA is like a computer program, Everything is programmed in DNA and it controls and give instructions to our cell to do responsible tasks. DNA contains some special types of letters(program)that your cell can understand.

99.9% of our DNA sequence is same as other humans, Then you may be wondering that there is only little difference between einstien and you. But the remaining 0.1% makes a lot of difference between you and rest of the people.
Our entire DNA sequence would fill 200 1,000-page New York City telephone directories.
If unwound and tied together, the strands of DNA in one cell would stretch almost six feet but would be only 50 trillionths of an inch wide.
If all the DNA in your body was put end to end, it would reach to the sun and back over 600 times (100 trillion times six feet divided by 92 million miles).
The CODIS databank (COmbined DNA Index System) is maintained by the BI and has DNA profiles of convicted criminals.
Lengths of connected DNA molecules, called genes, are like tiny pieces of a secret code. They determine what each organism is like in great detail. Almost all the DNA and genes come packaged in rod-like structures called chromosomes--humans have 46. There are 22 almost identical pairs, plus the X and Y chromosomes, which determine if a human is male (one X chromosome and one Y chromosome) or female (two X chromosomes).
The DNA information in a single sperm contains 37.5 MB worth of data? Which means that an average ejaculation almost instantly transfers roughly 1.5 1,500 terabytes of data. Suddenly USB 3.0 doesn't look that impressive when compared to what Mother Nature's been using for years.
An animal's entire code, comprising a long string of the letters A,G,C,T, is called a genome. The human genome is about three billion letters long. Just think if that was written in the normal letter size like the letters you are reading now, then it covers kilometers of distance.
Most of our genome is made of junk DNA. This junk is compressed either of deactivated genes that were once useful for our non-human ancestors(like a tail), or parasitic DNA from virus that have entered our genome and replicated themselves hundreds or thousands of times over the generations, but serve no purpose. Genome size is therefore not related to the complexity of life. For example, the genome of the unicellular amoeba has been reported to contain more than 200 times the amount of DNA in humans.

10. 15. There may be a huge black hole in the very middle of the most of the galaxies.
11. 16. The Universe is probably about 15 billion years old, but the estimations vary.
12. 17. One problem with working out the age of the Universe is that there are stars in our galaxy which are thought to be 14 to 18 billion years old – older than the estimated age of the Universe. So, either the stars must be younger, or the Universe older.
13. 18. The very furthest galaxies are spreading away from us at more than 90% of the speed of light.
14. 19. The Universe was once thought to be everything that could ever exist, but recent theories about inflation (e.g. Big Bang) suggest our universe may be just one of countless bubbles of space time.
15. 20. The Universe may have neither a centre nor an edge, because according to Einstein’s theory of relativity, gravity bends all of space time around into an endless curve.
16. 21. If you fell into a black hole, you would stretch like spaghetti.
17. 22. Matter spiraling into a black hole is torn apart and glows so brightly that it creates the brightest objects in the Universe – quasars.
18. 23. The swirling gases around a black hole turn it into an electrical generator, making it spout jets of electricity billions of kilometers out into space.
19. 24. The opposite of black holes are estimated to be white holes which spray out matter and light like fountains.
20. 25. A day in Mercury lasts approximately as long Saturn's moon Titan has plenty of evidence of organic (life) chemicals in its atmosphere.
21. 2. Life is known to exist only on Earth, but in 1986 NASA found what they thought might be fossils of microscopic living things in a rock from Mars.

1. 7. The full cost of a spacesuit is about $11 million although 70% of this is for the backpack and the control module.

1. 8. Ever wondered how the pull of gravity is calculated between heavenly bodies? It's simple. Just multiply their masses together, and then divide the total by the square of the distance between them.
2. 9. Glowing nebulae are named so because they give off a dim, red light, as the hydrogen gas in them is heated by radiation from the nearby stars.
3. 10. The Drake Equation was proposed by astronomer Frank Drake to work out how many civilizations there could be in our galaxy - and the figure is in millions.
4. 11. SETI is the Search for ExtraTerrestrial Intelligence - the program that analyzes radio signals from space for signs of intelligent life.

Your pet isn't the only one in the house with a shedding problem. Humans shed about 600,000 particles of skin every hour. That works out to about 1.5 pounds each year, so the average person will lose around 105 pounds of skin by age 70.

Interesting and weird space facts...

Every year the moon moves about 3.8cm further away from the Earth. This is caused by tidal effects. Consequently, the earth is slowing in rotation by about 0.002 seconds per day per century. Scientists do not know how the moon was created, but the generally accepted theory suggests that a large Mars sized object hit the earth causing the Moon to splinter off.


If you shouted in outer space, even the person right next to you would not be able to hear what you said. Sound travels as pressure waves through air. Because there is no air in outer space, there is also no sound. So don’t bother trying to tell your astro-buddy his fly is down, he ain’t gonna hear you.




The lack of gravity in outer space combined with the inherent surface tension of liquids causes them to form into free-floating spheres. That’s why astronauts often drink water out of a straw in a tightly sealed container. Although they can suck free-floating water bubbles in the weightlessness of zero-gravity space if they want to!





 One problem with working out the age of the Universe is that there are stars in our galaxy which are thought to be 14 to 18 billion years old – older than the estimated age of the Universe. So, either the stars must be younger, or the Universe older.




After spiraling into a black hole is torn apart and glows so brightly that it creates the brightest objects in the Universe – quasars.

Was Nostradamus a Real Prophet?

Was Nostradamus a Real Prophet?

Michel de Nostredame or Nostradamus was a sixteenth century purported seer and apothecary (the medieval term for medical practitioner), who wrote down a thousand prophecies, many of which, according to those that believe him, have now come true.  His favorite “seering” method was scrying, which involved gazing into a mirror or a bowl of water and waiting for a vision to appear.

One of the most famous is supposed to have referred to the death of Henry II, who died from a jousting accident. The Quatrain, which is how Nostradamus’ prophecies were organized, refers to a single battle, where two wounds become one, piercing the eyes through a “golden cage”. While it is true that Henry II was pieced through the eye through a golden jousting helmet, and died of two separate wounds, the part of the quatrain that refers to the older lion being slain by the younger one seems not to be applicable, as both Henry II and his opponent were around the same age. Another famous prophecy that Nostradamus made refers to a fire in London by name in the year ’66. In 1666, there was a huge one-and-a-half mile by half a mile fire that destroyed the city. Nostradamus is also said to have predicted the French Revolution and Napoleon, Hitler’s rise to power, World Wars I & II, the death of Princess Diana, the Apollo moon landing, and the September 11 terrorist attacks.

Whether or not you believe in his predictions, Nostradamus left an impressive legacy, after all his writings are still being printed almost half a millennium after being published for the first time. The mystery in Nostradamus writings is whether or not his predictions have anything to do with the paranormal or as many skeptics believe, just a statistical exercise. Considering 500 years of history and a 1000 vague, timeless and open to interpretation writings, it is natural that a few of those predictions will coincide perfectly with a major event every now and then.

The Third Eye Man November 1949

Students from the University of South Carolina in Columbia were walking near the Longstreet Theater late one evening when they were stopped in their tracks by the appearance of a gray faced man wearing a silver suit, who removed a manhole cover and disappeared into the sewer. At the time, the strange man was dubbed, “Sewer Man,” but he would soon be given a much different name following another, more terrifying encounter in April 1950.

This time, a policeman discovered a man in silver near the remains of mutilated chickens. He shone his flashlight on the figure. To his horror, the strange man had a third eye in the center of his forehead. The policeman went to his squad car and radioed for help. By the time other officers arrived, the man was gone. Another encounter by students in the Sixties in the steam tunnels under the university kept the memory of Third Eye Man alive.

Although the tunnels were thoroughly searched, no physical evidence of Third Eye Man’s existence has ever been found. Is he a ghost? A creature? An alien? A prank? No one knows, but sightings continued into the early 1990s.

The Crystal Skulls

One of the major global phenomena that still remain unsolved, is the origin of crystal skulls. Who created them and what they served? These are still the questions that remain unanswered.

So far 13 skulls have been found which are kept in museums and private collections. However according to some estimates there are more than 20. They are replicas of human skulls found in Central America and Tibet. The rock crystal from which they were made, is difficult to process. Topaz, corundum and diamond is what the rock crystal is made up of. It is very difficult to process some of these minerals, if torn down.

The most beautiful crystal skull was found in the year of 1927 in Central America. It was many years in the home of Hedzhis-Ann Mitchell, the adoptive daughter of an archeologist. In excavations in Lubaantum, the city in which the Mayans lived, the girl dug up a wonderful gift for her 17th birthday.

Apart from the skull that was found so was its lower jaw, which can be fitted with articulated bolts which is also made of rock crystal. To this day, the skull of Lubaantum has not changed.

Scientists have studied the multiple findings.

When you turn the skull with the "face" to the flames of fire, it's eye holes sinister light. This is due to the extreme precision with which it is made. The crystal is cut so that under certain conditions, it can receive optical effects. In the occipital region it has a lens that collects light and directs it to the eye holes.

The crystal is treated so that it has no trace of a tool. According to calculations of scientists to make such a perfect piece of crystal skull, that meets all the anatomical details, seven million hours of continuous working is required. Which equals 800 years of nonstop work.

And if the skull is processed 12 hours a day, it would drag on performance targets of 1, 600 years. Only polishing the surface would go to 300 years.

After communicating with the crystal skull, many people complained of nightmares, terrible visions, receiving headaches and even lapsing into a trance.
