Action or a game walk on hot coals without injury is often seen. There are allegations of people who do that using magic because the body does not burn walking on fire. 

But there is a scientific explanation of why a person could walk on coals without burning? 

The first, most of the action goes on fire use traditional fire originating from the pieces of wood. 

Pieces of wood are composed of many carbon compounds, some volatile organic molecules, including water evaporate. 

These organic molecules would be easy to evaporate when heated, due to the heat released by the fire will vaporize any volatile organic compounds (volatile) and also water. Thus obtained only a nearly pure carbon compounds and carbon is one of the lighter elements. 

Structure of lightweight carbon is a poor conductor of heat, so it takes a relatively long time to transfer heat from the coals to one's skin. 

But if coal is produced from metal, then heat transfer will occur in real time and someone will get severe burns. 

Second, the ash produced from combustion processes can also act as a thermal barrier or insulator layer, so that heat transfer to a person's skin will become slower. 

Not that it is impossible burn at all, because the heat transfer can still occur. If someone stood on the coals for some time, then the person will get a pretty serious burns. 

But if someone is limiting skin contact with hot coals for example, in a very short period of time or walk quickly, then the legs will not get hot enough to burn skin. 

That is why the actions of walking on fire does not make someone burn. But it's not easy to do and it takes a certain expertise. 

The burn itself will occur when the body exposed to a substance of high temperature and one of the major causes of burn accidents are exposed to fire. 

Based on the degree of tissue damage, so burns can be divided into three types, namely: 

First-degree burns, which damage the lining of the epidermis which is characterized by mild swelling in the area, redness and blisters. 

Second-degree burns, which covers damage to the epidermis and some dermis (deeper skin layers), arises a sense of pain, infection and sometimes dehydration. 

Third-degree burns, which covers damage to all layers of the dermis, the layer of muscle and bone as well as infection.

In the movie, when he found an ancient mosquito trapped in bucket dinosaur blood from his stomach and then taken and extracted DNA was then inserted until the eggs hatched alligator embryos and Jurrasic Park were ready to open.

A series of steps may sound quite strange in 1993 when the film was screened at the cinema blockbuster. Even today, in the world of genome sequencing, transgenic animals (hybrids), and bacterial artificial laboratory, the resurrection of extinct species of sounding a bit more feasible. Really?

Apparently, scientists may very well make the dinosaurs or dinosaur-like creature in a time not too far away. Unfortunately, the DNA molecule, the genetic instructions creator of life, always broken from time to time.

At 65 million years ago, when the last dinosaurs to fly, swim and walk on Earth, their DNA remains intact rarely more than 500 thousand years later. According to the dinosaur paleontologist Jack Horner of Montana State University, humans will never really find dinosaur DNA.

He and his colleagues discovered soft tissue from Tyrannosaurus Rex in 2005. Unfortunately, the findings do not contain material that could be used. "Soft tissue seems to consist of biomolecules other than DNA," said Horner.

In fact, if someday discover ancient dinosaur DNA, DNA that will fall apart, piece of code only along a few base pairs and how to 'sew' the pieces together.

Similarly, genome sequencing or blood fossilized dinosaur tissue may not be a viable route for their resurrection. However, geneticists create alternate pathways Jurassic Park.

In recent years, several groups working independently began to build a dinosaur DNA is active in one of the descendants of these extinct creatures, namely in the chicken genome has been sequenced in full.

Led Horner, scientists hope to grow chickens toothed, scaly, tail, and forelimbs. In short, they want to make 'ayamdino' and this will be very close to becoming a reality.

First, in 2005, developmental biologist John Fallon and Matt Harris at the University of Wisconsin experiment with a mutant chicken embryos when they saw a strange bulge emerging from the jaws of chicken fetus.

The mound was a sword-shaped teeth that are identical to embryonic alligator. Scalloped chicken embryos mutant has a recessive gene that kills the fetus before birth. As a side effect (not related to the death), the gene is switched from one gene to another which has lain dormant in the evolution of the chicken for at least 70 million years, genes of ancient dinosaur teeth.

Fallon and Harris created a virus that behaves like a recessive gene that is lethal in chickens but mutants were not lethal. When they put the virus into normal chicken embryos, chicken became a dentist.

Then, a paleontologist Hans Larsson at McGill University found that chick embryo begins with the tail. At a certain point of development of the chicks, genetic switch flips and tail were missing.

Using growth hormone to try to override the strike, Larsson and colleagues are trying to turn the switch back. Similarly, Horner believes the chick embryo could eventually grow genetically manipulated to replace the arm wing.

"The lack of a tail, the difference between wings and arms, and the lack of teeth is a subtle evolutionary changes in the basic plan of the dinosaurs," he wrote in a book written with James Gorman titled 'How to Build a Dinosaur'.

So, how long before the scientists created ayamdino? "Maybe the next few years because it all depends on funding," said Horner.

In a world where cancer is still incurable, not everyone thinks the rise of dinosaurs deserve part of the monetary supply for scientific research. On the other hand, some others think this is very cool.
