Lizards that clone themselves

Scientists from the United States and Vietnam to find it after noticing that all the lizards in the tank in the restaurant turned out to be androgynous females.

Leiolepis small lizard species previously undocumented ngovantrii can reproduce by cloning, according to CNN reports.

The story of the discovery occurred when a reptile expert Vietnam know that all the lizards who served in the dinner dishes in a remote province are female. He contacted an American colleague who then flew to Vietnam to help.

Dr. Lee Grismer that fly to Hanoi and then spent two days to go to the region, according to the CNN team encountered some obstacles in the way, including a restaurant owner who promises to give some of these lizards but could not be delivered.

"Unfortunately, the owner of the drinking and ended up drunk and roasting the lizards for subscription restaurant, so when we arrived there was nothing left."

The team then searched the other cafes and hire children to look for the lizards. They found 60 head and realized that the lizard is a new species.

"The lizard is entirely new lineage of life that are eaten and sold in restaurants," he said. "But the reptile is something that is not seen by scientists for hundreds of years."

However, Dr. Grismer says that eating lizards may not be popular outside of Vietnam.

"You try one bite the lizard cuisines and tastes like something very old and dead in your mouth," he concluded.

Why Gold Considered Valuable?

Since the beginning of human existence known, he has been considered the gold is valuable. Most likely the gold was the first metal known to man yan. One reason why the primitive man is interested in gold is that gold can be obtained in a free country, which means that gold can be found in small chunks that are not mixed with other metals or stones. Because it has a bright yellow color and shiny look, even the final days of any human being glad to have it and make jewelry of gold.

The value of gold increased when people realized that gold is the metal most easily done from all other metals. Malleable lump of gold to the thin and pliable enough to be bent without being broken. This means that human early age can make gold into the shape he wanted. For example at a time, gold is used as a hoop to tie the hair. From this model emerged the idea to make a crown and a small crown of gold.

Supplies of gold which can be obtained easily from the earth is very limited. Very soon the people who can not obtain the gold itself offers for mutual exchange of other goods in exchange for gold. That's the way how gold became the means of payment. Gold can not be damaged while other commodity-komodiri can be damaged, so the gold into a tool which stores the value for the future, and also a measure of value.

Then, the bankers keep the gold in their vault for security, and provide written guarantees for mengirimakn gold on request. From this practice, governments began issuing currency, or money, which is also merely an assurance to mengirimakn certain amount of gold on request.

It's why the Ocean Salty?

Once again we encounter the reality of our world that confuse us and there has been no answer. That fact is the presence of salt in the ocean. How salt can be there?

The answer is that we do not know how the salt into the ocean! Of course we do know that salt is a substance that can dissolve in water, and therefore into the sea with rain water. Salt in the earth's surface continuously dissolved and flowed into the sea.

But we do not know whether this led to a very large amount of salt contained in the sea. If all the oceans dried, there will be quite a lot of salt that can be used to build a wall 180 miles high and a mile thick. The wall can circumnavigate the globe at the equator! Or in other words, rock salt is obtained if all the oceans dried would be a big part about 15 times that of the entire continent of Europe!
Common salt we use is produced from seawater or salt water lake, a spring-eye dair saltwater, and from deposits of rock salt. Salt concentration in seawater ranges from approximately three to three and a half percent. Enclosed seas, such as the Mediterranean Sea and Red Sea, contain more salt in the water than on the open seas. Dead Sea, which covers an area of ​​approximately 340 miles square, containing approximately 11.6 billion tons of salt!
On average, one gallon of seawater contains approximately one quarter pound of salt. The basics of rock salt that forms in various parts of the world was originally formed by evaporation of sea water millions of years ago. Because rock salt is needed to form a roughly nine-tenths of the volume of water evaporated, people argue that the fundamentals of a thick rock salt are found deposited in what was formerly a part of the enclosed seas. Seas are evaporating faster than the fresh water coming in, so that the rock salt deposits were formed.

Most commercial salt obtained from salt stone. Commonly used way is to drill wells down to the basics that contain a fight. Pure water is pumped through a pipe. Water will dissolve the salt and the salt was pushed out through another pipe to the surface.

What causes emergence of Shadows?

Imagine a wanderer in the desert, dying of thirst. He looked away and saw a shadow of a lake has crystal clear water surrounded by trees. He staggered up to the shadow disappears and nothing but the hot sand in the vicinity.


The lake, which he sees is a distant shadow. What gives? The shadow is a hoax played by Nature in front of our eyes as a result of certain circumstances in the air. First we must understand that we can see an object because the rays reflected from the object to our eyes. Usually these rays reach our eyes in a straight line. So if we look at kekejauhan, we only see things that are above our horizon.


Now we turn to the tricks played by air with rays. In the desert, there is a thick layer of air above the ground which acts as a mirror. An object of this dense layer of air, the rays reflected to our eyes and we see the object as if it is above cakrawaka dab visible to us. Actually, we "see" objects that can not be seen by our eyes! When the sky is much reflected by the "mirror" this air, the sky sometimes looks like a lake, and we see the shadow.
On a hot day, when you approach the crest of a hill, maybe you will think that the road ahead was wet. This is also a shadow! What you see is the light of heaven that has been bent by the hot air just above the pavement so that it appears to have originated from the road itself.
Shadows also occurred at sea, with images of ships that were sailing across the sky! In this case, there is cold air near the water and hot air above it. Distant ships, which are far away on the horizon, can be viewed as waves cahanya from ships that are reflected by a layer of hot air and we saw the ship in the sky!
One of the images are very famous in the world occurred in Sicily, along the Strait of Messina. Messina city reflected in the sky, and the oxen imaginary seem to float in the air. The Italians called Fata Morgana, by name Morgam Le Fay, who is considered as an evil fairy who causes this shadow.

What Causes Smelly Fragrant Flowers and Colour?

Surprisingly, about a plant often notice and admire the "flowers" when we actually do not notice the flowers at all! If we think of flowers as something that has a bright color that grows on a tree, we may be wrong.

For instance, "the leaves of the flowers" bloom "dogwood growing in the spring flowers are not leaves at all. Likewise the leaf midrib, which is white on the plants 'caklas' is not a flower. Poinsetia flower collection is another example of leaf- yabng colored leaves and flowers instead of real yangs.
Instead, files are bearded at the ends of the grass is actually a flower! Ears of corn are not actually cook the flowers. According to the botanist, flowers are a bunch of parts whose function is to produce pollen or seeds or both. Only plants that produce seeds that have a flower. And only parts of a plant closely related to the formation and production biki which can be regarded as parts of the flower.

What causes the flowers smell nice? Flower has a fragrance when the leaves of the flowers contain certain pure essential oils. These oils produced by plants as part of its growth process. These pure oils are substances that are very complex. In certain circumstances these complex substances that were damaged or decayed and formed into mintak volatile, which means mintak it can evaporate more easily. If this happens, we can smell the fragrance of flowers.

Special type of fragrance depends on the interest generated by the chemicals contained in the volatile oil and a combination of different also. The same oil is not only in the flowers of plants tetapis often also present in the leaves, bark, roots, and seeds. For example, oranges and lemons have a volatile oil in the fruit, almonds in the seed, cinnamon in the bark, and so on.

What causes colored flowers? "Anthocyanins" is the name for the pigments that give color to red, mauve, purple, and violet. Pigments are dissolved in the sap of cells of interest. Other colors like yellow, orange, and green, are the result of other pigments. These substances include chlorophyll, carotene, and so on. There is no chemical relationship between these compounds.

So we can connect the colors in the flowers with pigments called "anthocyanins" and with other pigments called "plastids." Anthocyanins groups provide a range of certain colors and the colors of plastids provide the rest.

Why Try the cheese holes?

Cheese is one of the most important dairy products and widely consumed. It is estimated there are more than 3000 kinds of cheese all over the world, from France, Germany, Holland, Denmark, Switzerland, Italy, Britain, the United States, and other European countries. Many yes! but Had not you find a hole We used clay pit cheese on the image or in movie cartoons?

Well .. this story knp ya ntu cheese can be perforated:
cheese holes in swiss common cause of these holes krn propioni bacteria These bacteria are commonly found on balokan cheese, Limburger and Liderkanz. Bacteria propioni provide sweet and savory flavors in cheese. Cheese made from milk acidified. Acidification process was aided by the yeast and bacteria. When the cheese through the preservation, bacteria propioni dropping such gases. Bubbles of gas that has shaped round holes in Swiss cheese.

Because of these holes, Swiss cheese so it is so unique and distinctive Several other types of cheese to obtain a special form of the fungus and its own particular flavor. Blue veins that appear on Roquefort cheese is caused by the fungus Penicillium roquefortii. This fungus makes the cheese surface becomes slippery. Medium cheese Camemberti overgrown gray fungus called Penicillium camemberti white. This fungus causes the color to yellowish.

History of Cheese
The existence of the cheese begins when a shepherd found a dairy cow which he kept in a bag of goat leather, frozen and fermented when left in the cave. A hungry man eating blob before and liked the taste of milk. Since then deliberately fermented milk to produce food that we later know as cheese. Long ago the farmers keep the rest of the milk and let it clot. After that, the lump of cheese lapped using tree stems, wrapped, and weighted down with stones as he left to become dry in the sun. To give a flavor, the cheese and then sprinkled with salt. In the 20th century, the industrialists to change the traditional way. They introduce many new types of cheese are rich in flavor. Cheese including high protein nutritional value. Cheese also produces great energy. It contains calcium and phosphorus, especially cheeses cooked. Cheese is very good to replace the milk, especially for those who do not like milk .

How Big Is An Atom Size?

Let's start by saying that everything we know about atoms today may change tomorrow. Science is constantly learning new things about the atom at atom crusher machines are made.
Surprisingly, the rich "atom" comes from the Greek word meaning "indivisible." The ancient Greeks regarded the atom as a particle of a substance is the smallest.
However, today we have discovered more than 20 different particles in this Aton! Scientists think that an atom consists of electrons, protons, neutrons, positrons, neutrinos-neutriono, meson-meson, and hiperon-hiperon. Electrons are particles that carry a negative electrical charge is very small. Proton, which weighs approximately 1836 times the weight of electrons, carrying a positive electrical charge. Neutrons, are still heavier, does not carry an electrical charge at all. Positron, which is about the size of approximately one per two thousand of the size of the electron, has no charge. Meson can be positively charged or negatively. Hiperon larger than the proton.

How to charge all particles or atoms are brought together to be is still unknown. But these atoms form the elements and different from each other. One thing that makes atoms different is based on weight, and thus, the elements are classified according to their atomic weights. For example, hydrogen is "1" on this list and the iron is "55". This means that an iron atom is 55 times the weight of a hydrogen atom.
But the weights are very small. A hydrogen atom weighs one in a million-million-million-million grams! To give another illustration of how small atoms are, let's see how many atoms are contained in a single hydrogen. The answer is approximately 6 followed by 23 zeros. If you start to count and calculate one atom per second, you will take ten million million years to count all the atoms are only present in one gram of hydrogen!

Sea Dogs Detect Prey With a mustache

A new study reveals how a dog can hunt marine fish, even in the murky water though. The result, seals use whiskers to detect it turns out the trail left by their prey in water, up to half a minute.
The biologists found that the seals can detect prey fish in the turbidity of water left by their prey. This behavior is similar to the ground following the smell of dogs to hunt their prey.

This animal's whiskers are so sensitive, so it can detect traces left by a vortex of fish, up to within half a minute. In turbid and dirty water, seals rely solely on extra flavorings to hunt prey that try to escape.

Until now, the whiskers of seals known to only work when physically touching an object, but after closer examination, it appears that this organ is known to play a much more important.

The researchers believe the sea dog's whiskers are as effective as eccholocation to dolphins and whales that serve as prey detection.

Dr. Wolf Hanke, zoology expert at the Center for Marine Studies at the University of Rostock, Germany, said that the seals can follow in the footsteps of fish after the 35 seconds at a distance of about 230 feet (70 m).

He said, "Mustache seals have a function similar to the echolocation whales and dolphins."

Although testing is only done in general, they believe any other species such as sea lions, also enabling their whiskers like this.

The scientists claimed, they also have preliminary findings that show, the seals can even detect information about the size and speed of underwater prey in the lane.

Prof. Guido Dehnhardt, which is also based at the University of Rostock and worked on this research says, seals the possibility of using a mustache and senses of hearing to track the fish, before his eyes a few feet to the chase.

"Now we not only know, that seals can read the trail information and directions, but we also found data that showed, they can also read the size and shape of an object," he said.

"It shows that the seal's whiskers are very sensitive to touch on, as a means to explore objects that physical contact with the mustache. Information hydrodynamic sensing is something entirely different and expansion information spectrum is physically just a whisker over the response of these animals," Prof . Guido explains.

So, a dog's whiskers sea, proved to have benefits that are very useful for the continuity of life.
