Did you know about the most complicated organ of human body?


The human brain is the most complex organ in the human body and probably the most complex creation present on this universe. It is evident that, the world’s greatest man made wonders are a result of the human brain making it the most amazing feature in a human being. The human brain with its complexity acts like a storage device which holds safely a person’s most cherished memories. A person’s personality is by far influenced by the brain as well as generation of human consciousness which gives a person passion, motion and emotion. A command center for the central nervous system, the brain serves human beings with ample physical and cognitive abilities. This are just a few vital roles that the human brain performs but the most amazing thing about the human brain are the many facts that are less known by many people with a fully functional brain.

1 – The human brain is the only organ in the human body that lacks nerves despite the fact that it acts as the central command for the central nervous system. This simply implies that, the human brain feels no pain.

2 – The human brain consumes the largest portion of the total energy that is generated in the human body. To be precise, the brain consumes 20% of that energy despite the fact that it only represents only 2% of the total body weight. The energy is vital for maintaining healthy brain cells and fueling nerve impulses.

3 -The number of neurons present in the brain is approximately 100 billion which is about 15 times of the total human population on earth. This high number of neurons increases the processing ability of the brain.

4 – The human brain is regarded as the fattest organ in the human body. About 60% of the human brain is comprised of fat which is the highest concentration of fat that is present in a single organ in a healthy human being. Furthermore, 75% of the total brain mass is comprised of water which regulates various functions in the brain.

5 – The neocortex is the portion of the human brain that is responsible for language and consciousness. It makes up approximately 76% of the human brain and making it the largest when compared to that in other animals.

6 – It is believed by many that, human beings use less than 10% of their brain. This is a misconception because each and every part of the brain has a known function.

7 – During early pregnancy, neurons have shown to multiply at a rate of 250,000 neurons per minute

8 – About 15-20% (750ml) of the total cardiac output is directed to the brain every minute.

9 – The energy consumed by the brain which is approximately 25 watts is sufficient enough to illuminate a light bulb.

10 – The human brain is not as perfect as it is thought of since in many instances it has been found to fool human beings making them to perceive things differently from the reality.

There can be little doubt, the human brain is truly an incredible body organ that requires maximum care to keep vital body processes running.

British Scientists Supposedly Cloned a Dinosaur — Here's What Really Happened!


Scientists at the University of Florida have successfully cloned a dinosaur, a spokesman from the university said yesterday.

The dinosaur, a baby Apatosaurus nicknamed “Spot,” is currently being incubated at the University of Florida’s College of Veterinary Medicine.

The scientists extracted DNA from preserved Apatosaurus fossils, which were on display at the university’s museum of natural science. Once the DNA was harvested, scientists injected it into a fertile ostrich womb.

“Ostriches share a lot of genetic traits with dinosaurs,” said Dr. Norman Trudell, a biology professor at UF and the project’s leading scientist. “Their eggshell microstructures are almost identical to those of the Apatosaurus. That’s why the cloning worked so perfectly.”

Those in the scientific community say the dinosaur cloning – the first ever of its kind – is a milestone for genetic engineering.

"I used to think this kind of thing could only happen in the movies," said Dr. Gemma Sheridan, a LJMU chemistry professor. "But we're making it happen right here in our lab. It's astounding."

Confederations Cup: Brazil's Neymar ready for historic Maracana tussle with Spain!

 





Brazilian star Neymar vowed on Friday to help fire Brazil to a third straight Confederations Cup title at the expense of world champions Spain to show fans they can expect fireworks when he arrives in La Liga with Barcelona.

"We will be playing for our families, our friends, but above all for the Brazilian nation.

"We are ready for what will be an historic match," the 21-year-old starlet said as he looked forward to a mouthwatering encounter with the Spanish on Sunday in Rio's Maracana stadium.

"We shall be defending our country," added Neymar, who scored in all three group games before helping to create goals for Fred and Paulinho in the semi-final success over Uruguay.

"It will be a great match. Both teams are out to create history," added Neymar, noting that while Brazil are gearing up for an even bigger prize next year when they host the World Cup for the first time since 1950, landing Spain's scalp on Sunday would send out a message that a new Selecao has landed.

Spain, who have never won the Confederations event, will go into action on the back of a record 29 matches unbeaten and seeking an unprecedented fourth consecutive victory in a major tournament after Euro 2008 and 2012 triumphs sandwiched their maiden World Cup success in 2010.

Brazil meanwhile came into the tournament having dumped former coach Mano Manezes for 2002 World Cup-winning handler Luiz Felipe Scolari, despite the latter enduring some less than stellar recent spells in club football with Chelsea and Palmeiras.

Since Scolari's return, the auriverde have slowly begun to shape a team based on a blend of youthful exuberance encapsulated by the likes of Neymar himself and the experience of older players such as Fred, whose three goals, following a run of five in six friendlies, have fired up the new machine.

"This will be a real final showcasing great players. It should be a great game and I just hope I come off happy and a champion with my team," said Neymar, who added he was not afraid of the close attention the Spanish defence will undoubtedly seek to shackle him with.

"I will just go out there and do what I always do to help my team - take free kicks, spray passes around, score goals. I want to help the team."

Brazil are desperate to showcase the giant nation at this event as well as the World Cup, amid an ongoing battle to revamp sagging infrastructure and sometimes chaotic public services.

Since before the event started on June 15, more than 1.5 million Brazilians have been out in the streets in more than 100 cities protesting at the vast bill of some 15 billion dollars to host the two football jamborees, angry that the government has put money into that rather than health, education and transport.

A recent poll indicated two-thirds of citizens back the World Cup but the protests have continued and President Dilma Rousseff has been forced to promise wide-ranging institutional reform.

In allusion to the protests, Neymar said that just as the pressure was on the team to win trophies so it was on the government to improve the country's lot.

"The people know the importance of what is happening in Brazil and we are pleased if we can bring joy to the many who are not happy. Of course we all back the protests - as long as they are peaceful, without violence or vandalism.

Eating fish can lower breast cancer risk!

 
A new study has found that fatty acids found in fish are associated with lower risk of breast cancer.The results show that each 0.1 g per day or 0.1 percent energy per day increment of intake of n-3 polyunsaturated fatty acid derived from fish was associated with a 5 percent reduction in risk.

To achieve this risk reduction, intake of oily fish such as salmon, tuna or sardines should be 1-2 portions per person per week.Breast cancer is one of the most common cancers, accounting for 23 percent of total cancer cases and 14 percent of cancer deaths in 2008.

Studies suggest that a healthy diet and lifestyle is crucial for the prevention of breast cancer, and dietary fat is one of the most intensively studied dietary factors closely related with risk.

The fatty acid found in fish is involved in chemical messaging in the brain, helping to regulate blood vessel activity and areas of the immune system.Marine n-3 polyunsaturated fatty acid was associated with a 14 percent reduction of breast cancer between the highest and lowest category of the fatty acid intake.

The risk was lowest in Asian populations, probably because fish intake is much higher in Asia than in western countries, the authors said.

Massive Coronal Hole on the Sun!........


NASA’s Solar Dynamics Observatory captured this picture of the sun on June 18, 2013, showing a huge coronal hole – seen here in dark blue -- spread out over almost the entire upper left quadrant of the sun. A coronal hole is an area of the sun’s atmosphere, the corona, where the magnetic field opens up and the material flows quickly out. This results in a cooler and less dense atmosphere than the surrounding areas. This coronal hole is at least 400,000 miles across, which is more than 50 Earths side by side. Coronal holes spew out fast solar wind, probably traveling at about 400-500 miles per second. This is roughly twice the speed of the normal solar wind, the solar material that is constantly streaming off the sun in every direction to fill the solar system.

Coronal holes were first spotted by NASA’s Skylab in the early 1970s. Scientists now know that their size and number varies in concert with the sun’s solar cycle, which reaches a maximum of activity approximately every 11 years. Every time the sun heads toward that maximum, currently expected for late 2013 or early 2014, the coronal holes move closer and closer to the sun’s poles.

This image of the sun from June 18, 2013, shows a coronal hole – that is, an area of cooler, less dense material in the sun’s atmosphere, the corona -- in the upper left side, represented in blue. In this image from NASA’s Solar Dynamics Observatory, the blue color represents light in the 171 Angstrom wavelength, which shows the coolest material present in the image. Two other wavelengths of light are also shown in the picture: 211 Angstroms, in red, and 193 Angstroms in brown. Credit: NASA/SDO.

Did you know?: Early flying dinosaur hunted slippery fish!

Prior to this, paleontologists believed microraptors, which were about the size of a modern day hawk, lived in trees where they preyed exclusively on small birds and mammals about the size of squirrels.

Representational picture
Microraptor, a small flying dinosaur was a complete hunter, able to swoop down and pickup fish as well as its previously known prey of birds and tree dwelling mammals, a University of Alberta led research has revealed.
U of A paleontology graduate student Scott Persons said that new evidence of Microrpator`s hunting ability came from fossilized remains in China.

“We were very fortunate that this Microraptor was found in volcanic ash and its stomach content of fish was easily identified,” he stated.
Prior to this, paleontologists believed microraptors, which were about the size of a modern day hawk, lived in trees where they preyed exclusively on small birds and mammals about the size of squirrels.

“Now we know that Microraptor operated in varied terrain and had a varied diet. It took advantage of a variety of prey in the wet, forested environment that was China during the early Cretaceous period, 120 million years ago,” said Persons.

Further analysis of the fossil revealed that its teeth were adapted to catching slippery, wiggling prey like fish. Dinosaur researchers have established that most meat eaters had teeth with serrations on both sides that like a steak knife helped the predator saw through meat.
But the Microraptor`s teeth are serrated on just one side and its teeth are angled forwards.“Microraptor seems adapted to impale fish on its teeth. With reduced serrations the prey wouldn`t tear itself apart while it struggled,” said Persons.

“Microraptor could simply raise its head back, the fish would slip off the teeth and be swallowed whole, no fuss no muss,” he added.Persons likens the Microraptor`s wing configuration to a bi-plane. “It had long feathers on its forearms, hind legs and tail. It was capable of short, controlled flights,” he said
This is the first evidence of a flying raptor, a member of the Dromaeosaur family of dinosaurs to successfully prey on fish.
