Amazing and Interesting facts about your Brain and DNA.

DNAWondering 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.

Facebook, The ultimate giant


                                              Facebook, The ultimate giant.

Do you know Facebook has:- 


facebook timeline, social network #100 billion hits per day   
 #500 million active users
 #100 billion hits per day
 #50 billion photos 

 #2 trillion objects cached, with hundreds of millions of requests per second
 #130TB of logs every day.


facebook like, social networkFacebook is considered more addictive than cigarette and alcohol.

Facts about space that you have never heard before

  1. Mercury is almost the densest planet in the solar system and is second only to Earth
  2. The largest known crater on Mercury, the Caloris Basin, has a diameter of 1,550 km
  3. As of 2012 Mariner 10 and MESSENGER are the only two spacecraft to have visited Mercury
  4. It is estimated Mercury’s core makes up 42% of its volume, for comparison Earth’s core makes up 17%
  5. Mercury has the highest orbital eccentricity of all the planets with its distance from the Sun ranging from 46 to 70 million km
  6. While Mercury has at atmosphere it is constantly being stripped and replenished
  7. Mercury is named after the Roman messenger to the gods
  8. The Milky Way galaxy is whirling rapidly, spinning our sun and all its other stars at around 100 million km per hour.
  9. 14. The Sun travels around the galaxy once every 200 million years – a journey of 100,000 light years.
  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.
  22. 3. Most scientists say life's basic chemicals formed on the Earth. The astronomer Fred Hoyle said they came from space.
  23. 4. Oxygen is circulated around the helmet in space suits in order to prevent the visor from misting.
  24. 5. The middle layers of space suits are blown up like a balloon to press against the astronaut's body. Without this pressure, the astronaut's body would boil!
  25. 6. The gloves included in the space suit have silicon rubber fingertips which allow the astronaut some sense of touch.

  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.
  5. 12. The Milky Way galaxy we live in: is one among the BILLIONS in space

Interesting and weird space facts...


moon landing, apollo 11, nasaEvery 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.


space, astro, pressureIf 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.




space, astronaut, sky, suit, nasaThe 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!





star, universe, light year 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.
