Heaven And HellA holy man was having a conversation with the Lord one day and said, “Lord, I would like to know what Heaven and Hell are like.”

The Lord led the holy man to two doors. He opened one of the doors and the holy man looked in.

In the middle of the room was a large round table. In the middle of the table was a large pot of stew which smelled delicious and made the holy man’s mouth water.

But the people sitting around the table were thin and sickly. They appeared to be famished. They were holding spoons with very long handles that were strapped to their arms and each found it possible to reach into the pot of stew and take a spoonful, but because the handle was longer than their arms, they could not get the spoons back into their mouths. The holy man shuddered at the sight of their misery and suffering. The Lord said, ‘You have seen Hell.’

They then went to the next room and opened the door. It was exactly the same as the first one. There was the large round table with the large pot of stew which made the holy man’s mouth water. The people were equipped with the same long-handled spoons, but here the people were well nourished and plump, laughing and talking.

The holy man said, “I don’t understand.”

“It is simple” said the Lord, “In this place the people have learned to feed one another.”

 

Solved: Which Came First

They’ve cracked it at last! The chicken DID come before the egg.

Which Came First

The chicken wins!

One of the most puzzling and famous life questions has stumped people for generations. It’s the question of which came first: the chicken or the egg? In order for there to be an egg, a chicken would have had to lay it. In order for there to be a chicken, it would have had to hatch from an egg. It seems as though either answer could be the correct answer; until now.

Dr. Colin Freeman from Sheffield University along with colleagues from Warwick University have figured it all out. Their research project originally aimed to figure out how animals make eggshells because it’s an extraordinarily strong yet lightweight material that no human has been able to replicate, and the researchers hoped to learn how to develop a manmade equivalent by learning about the way animals make eggshells.

Chickens were chosen as their test subjects simply because the protein was easy to study. The study began when Freeman and his colleagues used the UK Science Research Council’s super-computer called HECToR (High End Computing Terascale Resource), which is based in Edinburgh. The “ingredients” used to make eggshells were programmed into HECToR, and that was it. The computer was left to produce results on its own, and it took weeks for HECToR to figure out how chickens make eggshells.

When HECToR finally arrived at a conclusion, the researchers were stunned when they realized that they had solved the age old question. After years and years of debate, it was finally determined that the chicken came before the egg.

“It had long been suspected that the egg came first, but now we have the scientific proof that shows that in fact the chicken came first,” said Freeman.

What they found was a protein, called ovocledidin-17 (OC-17), that exists only in a chicken’s ovaries and is vital to eggshell formation in chickens. The protein acts as an ongoing builder that pieces microscopic parts of the shell together by converting calcium carbonate into calcite crystals. The shell would not exist without this protein, which only exists in chickens, so the end result is that the chicken came first.

The protein was discovered before this research project, but HECToR made it easier for the researchers to observe the process “in microscopic detail,” thus understand the proteins significance in the eggshell-making procedure.

So what does this mean for those who always thought the egg came first? Freeman and his colleagues referred to some theories that suggest that chickens’ “ancestors evolved to create hard eggs around the time of the dinosaurs.”

In addition to answering the question that has burdened the human race for ages, the results of this study could be advantageous in the medical field since human bones and teeth are made in a similar way as eggshells. This could lead to a better understanding of how to rebuild human bones. Also, the study could help figure out how crystal structures can be made and destroyed (since the eggshells are made up of microscopic crystals). Learning how this can be done could lead to the elimination of limescale crystals on pipes and kettles.
