invisibility of ornamental fish from japan

TOKYO - Japanese researchers will never run out brilliant ideas.

Having previously transparent frogs breed, now Japanese researchers successfully breed goldfish invisibility. naked eye, the clouds can be seen directly carp heart is ticking along with other organs.
invisibility was developed as an effort to reduce the need for surgery in every biology classes at school. Previously, the practice of animal dissection in biology class is mired in controversy from many quarters in Japan.
research team combined Mie University and Nagoya University produces goldfish called 'ryukin'. This species developed from breeding carp at the time of hatching is not perfect with pale Mas Fish.
can see directly the heart and other organs of the fish, because the scales and skin has no pigment, "said Professor Yutaka Tamarus as quoted by AFP on Wednesday (30/12/2009). translucent it will be live for 20 years, while its length can grow to 25 centimeters and the weight reaches two Kilogram. 2007, a group of researchers announced the successful develop transparent frog.
Masayuki Sumida, a professor of the Institute for Amphibian Biology, Hiroshima University, estimates that this Transparent frogs will be circulated widely in the laboratory as well as schools in Japan next year.

Palenque (Meksiko)

Palenque ruins are one of the most important Mayan archaeological sites in Mexico and Central America. The town is built on a cliff with beautiful views of the Gulf of Mexico, Palenque as if hidden in a tropical forest in the foothills Tumbala, Chiapas, Mexico.
Although the analysis of pottery pieces that have inhabited the area began around 100 BC, but most of the remaining buildings constructed in the 6th to 10th century AD. The greatest ruler in this city is Pacal, who ruled in the year 603 AD, and making various innovative buildings that survive even more than that range innings Pacal 68 years. One of the remarkable buildings is the Palace, both walls and ceiling of the palace is filled with carvings depicting the ceremony and various activities of rulers and the gods, so that we can think how the life-rhythm of the Mayas of the era.
Until now only 34 of 500 possible buildings that successfully liberated from soil deposits, in case you can free up one more follow-up

Babilon (Irak)

These ruins are located about 90 km from the city of Baghdad, the original name of this town is "Bab-ILI" which means "gate of the gods". The city is widely known at the time of the classical era, as a beautiful city with the "Hanging Gardens" which is one of the Seven Wonders of the World.
The city was established as a center of government and culture, and glorious for about 15 centuries, ever since the arrival of the tribe Amor (about 1850 BC) until Alexander the Great, who eventually died there in 322 BC. Hammurabi (1892-1750 BC), one of the greatest rulers in Iraq also make this city as a center of government.

Machu Picchu (Peru)

The most famous ruins of all the Inca ruins. Machu Picchu as if located between two mountain peaks and is often shrouded in fog. These ruins can not be seen from the Urubamba Valley below, this place was built by the Inca nation, without at all using the wheel.
Machu Picchu was built in around the 15th century, but this place was not recorded by the Spanish Conquistador, who turned out to destroy the place in 1530. This place is also the purpose of development is still unknown, despite numerous signs that the place has many centers of worship.
Until now many archaeologists continue to search for evidence of purpose built venue.

We Shrinking Planet

Our planet is shrinking, said the Russian geologist. Since it was first built 585 kilometers of the earth has been reduced.

Vyacheslav Orlenok, professor of geology at the Kant Russian State University, Kaliningrad, comparing the ancient with the relief structure that existed at the moment.

He said 4.5 billion years ago, when the earth's surface just beginning to solidify a larger size. Estimated radius of about 6956 km and is currently 585 km has decreased.

For thousands of years the surface decreased by about 128 million square kilometers. Count is obtained by comparing the total area of all continents now reached 149 million square kilometers. "Depreciation is a major factor in processes such as tectonic movements in the continental platform," said Orlenok.

The reduced size caused by gravity and the mass loss caused by solar radiation, blowing away the hydrogen atoms of the earth's atmosphere, scientists explained. He has studied the formation of oceanic crust of the earth and for more than 30 years

Buckyball Birthday 25th

Buckyball ... Initially I thought that my connection is rather slow, because the second O in Google does not appear, but after a while it appeared the letter O in place a small ball spinning in the form of a hollow sphere, ellipsoid, or tube-shaped spherical fullerenes are also called buckyballs , and cylinders called carbon nanotubes or buckytubes.

Fullerene similar in the structure of graphite, which consists of stacked graphene sheets linked hexagonal rings, but can also contain pentagonal (or sometimes heptagonal) rings.

Before 1985, scientists knew only two forms of pure carbon structure of diamond and graphite. Both are wholly material composed of only carbon atoms. Each carbon atom in the diamond material, tied with four other carbon atoms form a tetrahedron pattern. This structure causes the diamond is very hard.

While in graphite, carbon atoms form a hexagonal layer of carbon-bound. Each layer hexagonal weakly bound with other hexagonal layer. This structure causes such as graphite is soft and oily. Structures like this also explains why graphite can be left in pencil on paper so that it can be used to write.

This day 25 years ago, exactly 4 September 1985 found a new structure of pure carbon in nature. This invention is answering questions in the beginning of the paragraph. New molecular structures called buckyball has a soccer ball-like pattern that consists of 20 hexagon (hexagonal) and 12 pentagon (segilima). The molecular structure is brought Smalley, Kroto, and Curl to the podium Prize in 1996.

This molecule consists of 60 carbon atoms with the chemical symbol C60. Meanwhile, a buckyball is taken from the name of an architect, R. Buckminster Fuller, who designed the dome of the new molecules with similar structures such as exhibition held in Montreal in 1967. Carbon molecules with structures similar to a soccer ball is also called by the name buckminsterfullerene or fullerenes.

The new molecule also has an effect like a ball, it can bounce and spin. Buckyball can rotate 100 million times per second. This molecule can be bounced if diempas to a hard surface such as steel. Then when squeezed or pressed, the molecule will return as the original form, like a rubber ball. And if compressed up to 70 percent of its original size, buckyball becomes harder than diamond doubled.

Curl, Kroto, and Smalley get these molecules at high temperature conditions and in a helium atmosphere. However, they only get a few products buckyball. In fact, it needs huge amounts to studying the nature and potential of these molecules in the future. Until the year 1990 discovered buckyball synthesis method produces a considerable amount of plasma method. This method was discovered by scientists from Germany and America.

When Smalley and his colleagues synthesize the buckyball or fullerenes, are not only found in C60 compounds. C60 is found in large quantities in bulk. Other structures found in the composition is less C70, C540, and other fullerenes containing hundreds of carbon atoms. In the synthesis method buckyball by American and German scientists, produced 75 percent C60, 23 percent of C70 'and the rest is a bigger carbon molecules. Since then, scientists have generally studied buckyball buckyball C60 compared with other more carbon atoms.

After the buckyball can be produced with large enough quantities, both Smalley and other scientists began to engineer, researching, and studying the properties of this unique molecule. One of the uniqueness is the empty space within the structure of the buckyball sphere. The researchers tried to fill it up with other atoms or ions to change the nature or the study bonding that occurs within the ball.

Various possibilities such as making plastics from the buckyball, carbon buckyball change into diamond at room temperature, as well as learn buckytube fiber or fiber-called nano-carbon (carbon nanotubes) have been carried out by researchers.

Like football players who will play ball in the field, researchers and scientists a variety of fields also play a soccer ball-structured molecules with different ways and rules in the laboratory on the pretext of science and learn the greatness of the Creator.
