Two researchers of the National Aeronautics Space Agency and ensure, crop circles in Berbah, Sleman, Yogyakarta, man-made. The assurance was made after a team of Lapan and Sleman district police investigation at the site on Tuesday (01/25/2011) afternoon.

"This man-made. We found some evidence that this is traditionally made," said Head Utilization Center for Space Science Institute Space and Aviation Agency (Lapan) Sri Kaloka Prabotosari on site this afternoon. Sri Kaloka came with other researchers, Nizam Ahmad.

The team from Lapan revealed evidence of man-made circle. The first evidence on the central point of the crop circle is a circle 5 cm in diameter. "The central point is, we found there was a hole as deep as 25 cm and 4 cm wide which we expected as the central point. The hole is made of a rod or pipe," said Sri Kaloka.

Lapan team finds the rice stalks are broken and uprooted roots. "That's a result of stepped on," he explained.

Sri Kaloka said the chances of crop circle makers are using ropes from the center of symmetry which is then made several patterns. "Our findings, not all the same pattern, there are big, some small. So we believe this man-made," said Sri Kaloka.

Meanwhile, a team of Sleman District Police also found human footprints. Footprints were previously not visible because of a closed trunk of a fallen rice.

Sleman police chief Irwan Ramaini AKBP present at the location of crop circles, said there was no trace of the UFO at the site.

"Based on our investigation with the team from Lapan, our expectations with the team from Lapan. This man-made," said Irwan Ramaini.

Furthermore, it will still secure the site and asked residents not to climb evidence near the site because it could jeopardize safety. One person was killed this afternoon after falling from the hill. Police will also look for the perpetrator's scandalous circle makers and examine his motives.

Crop circle at overseas

Change is a certainty. Development or growth is a process of change that often times we do not know the beginning and end boundaries. Change itself does not have the final edge.

Monday (1/24/2011) morning, Hamlet Rejosari, Jogotirto, Berbah, Sleman, Yogyakarta, the arrival of waves of people who want to watch a unique phenomenon, namely the mysterious circle (symmetric) in the paddy fields of seven residents. Similar phenomena occurred in various parts of the world, the largest in the United States and Europe and usually occur in wheat fields. Such phenomenon commonly referred to as crop circles. In the 20th century occurred some 10,000 crop circles, while the number of UFO cases have been reported since before 1940 to now around 550 cases with 434 cases of which accompanied by photographs (www.ufoevidence.org).

One of the spearheads circles who believe in aliens is Bob Dean, ufologist and former members of staff at Supreme Headquarters Allied Powers Europe (SHAPE) in the 1960s. Bob Dean among other states, information about UFOs and aliens, including secret military information with very high level and "forbidden announced to the audience."

Old phenomenon

Meanwhile, the crop circle phenomenon is a phenomenon that is quite old, has been there since around the year 1686, when Prof. Robert Polt, a professor of chemistry at Oxford, wrote the book A Natural History of Staffordshire who offend crop circle. He, among others mentioned forms crop circle is symmetrical and occurs on land that is fertile and in the open field. Crop circle by some people then thought to be the trail landing Unidentified flying object (UFO).

About whether or not UFOs then provoke long debate. On the one hand there are groups who believe in UFOs, unidentified flying objects are touted as vehicles aliens (aliens) from outer space. On the other hand there are groups who do not believe in the existence of extraterrestrials and UFOs.

The first group argues, crop circles are the traces of UFO landings. It's hard to imagine a complicated pattern in the region is wide enough; circle in Sleman diameter of about 60 meters to 70 meters can be made quickly without them knowing. Circle in Sleman known Ngadiran, one of the owners of paddy fields, on Sunday (01/23/2011). In fact, on Saturday circle does not already exist.

Parties who do not believe in UFOs confirmed, crop circles are man-made artwork. Astronomy professors of Astronomy Study Program Bandung Institute of Technology, Taufiq Hidayat, for example, said, "This circle is more of an art phenomenon. This is a man-made (Kompas, 25/1/2011). "

While the Institute of Aviation and Space Agency took to the field after yesterday asserted, a mysterious circle in Sleman is man-made because there is a hole in the middle of the alleged former site menancapnya shaft to form circular patterns. Similar phenomenon, Tuesday, was found in paddy fields in the hamlet Wanujoyo, Srimartani, Piyungan, Bantul, Yogyakarta.

This opinion is strengthened by the recognition of Doug Bower and Dave Chorley in 1991 that they created the mysterious circle at Longwood Estate. The idea of making their circle cetuskan 1978. The crop circle creators also have a complete official site by making a crop circle. For some, the UFO problem may come in the area of pseudo-science.

From the debate and put forward the fact that the two parties, the question "whether there are beings beyond our galaxy who often come to Earth using a UFO?" Still will reverberate long.

The long journey

The progress of science up to now, among others, still thick colored by ideas of logical positivism that is rooted in Descartes thought the speech "sacred": cogito ergo sum (I think, therefore I exist). This idea that pursed in the opinion of sensory sensation is the only source of knowledge. Mystical knowledge was abandoned.

So, we were thirsty to find the "answer". However, it reduced the problems of answers can be verified or not, subjective or objective, fact or value, and so forth. Then, if on a possible future study of new thinking in which there is an opportunity to develop a critical question: whether all the scientific methods developed so far are sufficient to dig up the truth?

As an illustration, the Earth is a collection of mystery that little by little we are trying to uncover his secret. The phenomenon of climate change so much in fact we could not even fully peeled completely. Similarly, the Milky Way galaxy where Earth is one of its members is only a very small part of the entire universe (cosmos).

Similarly, science trip that seemed endless. Travel science is still going very long. While the age of the earth reached about 4.5 billion years old, the age of modern humans (Homo sapiens) is still much younger, has not reached 1 million years. Perhaps the answer will be questions about the new UFO will be found in a tempatpada future. Maybe not because UFOs could be just the result of the construction of the human mind.

The discovery of a giant circle pattern in rice cultivation areas Berbah, Sleman, Yogyakarta, Sunday (01/23/2011), attracting the attention of observers of the phenomenon of Unidentified flying object (UFO). Such traces during these crop circles is often called an act associated with a foreign or alien creatures.

Crop circle has been frequently encountered in various countries. These reports are often delivered from local astonishing Latin America. Very large size can reach tens to hundreds of meters.

"With a very large size hard to say if the forms of such a giant man-made. So it can be concluded, there are other creatures that make it," said Dudi Sudibyo, observers are also observers of the UFO flight, when contacted Kompas.com, Sunday night.

Nevertheless, he did not deny that the crop circle could be also be made human. Moreover, in Yogyakarta that size is not as big crop circles in Latin America that its size in the tens to hundreds of meters.

"Scientific approach should still be put forward. I think people can not ignore it just like that. It should be investigated further," said Dudi.

He said that interested parties should immediately examine the document such as taking pictures in detail, measure its dimensions, including investigating how the crop circles that can appear on the site.

There are a number of experts who had previously tried to reconstruct the manufacture of crop circles. According to him, it is not impossible although it should be with the accurate mathematical calculations.

However, until now crop circle ever discovered remains a mystery because no one claimed him. Well, what about the crop circle in Yogyakarta, will remain a mystery?

Some scientists argue that life on Earth originated from outer space. Based on their theory, in the past the Earth once bombarded by asteroids that once brought the molecules of life.

Is it true that opinion? Lately, evidence is growing stronger. In 2009 Dr. Daniel Glavin find amino acid molecules in a fraction of asteroids that successfully reached the surface of the earth.

Amino acids are the basic building blocks of protein molecules, ie molecules that play a major role in life, from digesting food to immune function. Amino acids found in meteorites that is L-isovaline.

The evidence is strengthened by recent findings Glavin. Astrobiologi expert who became researcher at NASA's Goddard Space Flight Center in Greenbelt, this time finding the amino acids in meteorites 9 units.

In the studied meteorites, Glavin found that all amino acid-rich species L. Several others have amino acid amino acid L and R are balanced. None of the amino acid-rich R.

L amino acids are found in many kinds of living things. R amino acids seen from its structure is the "mirror" or the isomer (chemical term) of the amino acid L. R amino acid found only in bacteria and several species of sea slugs.

With these results, Glavin said, "This is evidence that the discovery of the past is not a coincidence. Indeed there is something that happens so that this meteorite is also rich in amino acids of L."

Glavin said the results of this study is also a clue. If life on earth consisted mostly of amino acids L, is not impossible that these molecules are actually derived from meteorites.

"The meteorite, meteorite amino acids may send L to the earth which will eventually help the formation of 'soup' prakehidupan. It could be a clue that we are destined to be a living being L," he said.

Glavin research results published in Meteoritics & Planetary Science, published January 17, 2011. Among the nine meteorites studied Galvin, one of which is Murchison which hit Australia in 1969.

In his research, Glavin also found that water had a role in increasing the number of L amino acids. Glavin found the existence of hydrated minerals (reacts with water) on the amino acid-rich meteorites L.

"Water seems to be the key. The more asteroids are in contact with water, the more L amino acid which is found," he said. However, the mechanism of water increases the amount of the amino acid L is unknown.

Meanwhile, Glavin also touched on the role of radiation in the dominance of the amino acid L. Cosmic ray radiation during solar still may be a bit young to support the creation and destruction of the amino acid L amino acid R.

All results can be a clue that other parts of the solar system was dominated by the amino acid L. So, if there is life on other parts of the solar system, life must also be dominated by the amino acid L.

"We seem to not want to see a reflection of the L amino acids in our solar system," Glavin said in an interview with Nature, January 19, 2011. L amino acids are often called left-handed amino acids.

Wow, its the first I knew this news. I think this is useful, so I share it with you ^^
I just knew that not only us have that ability, but fish has it too! Dou you want to know what that kind of fish? Can you guess it? ^^

It's Angelfish. Yapp, the scientists have proven this through research to it. Then, Scientists concluded that the fish can distinguish a lot or a little plus be able to count from 1 to 3.

Gerlai and Luis Gomez-Lalpaza from the University of Oviedo, Spain, attracted by the notion that fish angels choose to join the great herd when in a foreign environment. They do so for the sake of security.

Gerlai and his team put the fish in a special tank. Fish is faced with two herds with different amounts. The researchers then recorded the selected herd fish.

As a result, angel fish are able to choose a larger herd when the difference between the two herd number is doubled. When the difference in amount is less than two times, the choice of fish can not be predicted. With these findings, the researchers drew the conclusion that the angel fish can predict the number of flocks.

Aside from being able to predict the amount, angel fish can also be more precise count. "For example, fish can distinguish between 2 and 3," Gerlai exemplifies. "This shows the calculation of individual ability, not just estimate the amount," he said. Gerlai also explains, numeracy angel fish is limited only to 3.

Scientists guess, numeracy skills in these fish have no advantage for the fish. "Hence, this ability does not evolve," said Gerlai.

Unlike numeracy skills, the ability to predict the number of herds have advantages for angel fish. They choose their predictions herd more for security and the search for food. (National Geographic Indonesia / Alex Pangestu)

Mammoth? Its the extinct ancient animal and considered to have a kinship with the elephant, it is likely to be born again next four years. This possibility is the result of breakthrough of the cloning technology.

In the 1990s, scientists have attempted to study the possibility of recovery of heart cells from skin and muscle tissue of mammoths found in Siberia, Russia. However, these efforts failed because the cell nucleus has been badly damaged by extreme cold temperatures.

The science is far from hopeless. In 2008, Dr. Teruhiko Wakayama Development Center for Biology from Japan, RIKEN, technology pioneered cloning mice from cells of other mice that have been frozen for 16 years. The same technology will be applied to mammoths.

Efforts rebirth of extinct animals in about 5,000 years ago will be expanded Professor Akira Iritani from Kyoto University. "Now the technical problem has been resolved. All we need is a good sample of the soft tissue of mammoths frozen," Iritani said as quoted by The Daily Telegraph.

Iritani planning to travel to Siberia to find the remains of mammoths in the form of skin or tissue samples. Iritani just need this sample as small as 3 cm square. If not successful, he plans to ask for a sample of Russian scientists.

Nucleus of cells of skin or muscle tissue mammoths will be inserted into the African elephant egg cell that acts as a parent substitute (surrogate mother). Gestation period is estimated to need about 600 days. Previously, the preparation phase until the African elephant can be impregnated, takes about two years.

"Until now, the success rate in cloning a cow is very small. But, there are probably about 30 percent. I think we have ample opportunities for success and healthy mammoths could be born in four or five years," he said.

Mammoth is a family member elephantidae which is also a family of species that we know today. (National Geographic Indonesia / Raras Cahyafitri),

Doing sex? Before do it, you must read this! Let's check it out.. ^^

Since long research about reproduction in space to be one hot topic, especially when the space exploration program began to be encouraged. Build human colonies on other planets might still be a nightmare.

The reason, the results showed that sex in space is still at high risk if it is intended to produce offspring. Based on the study, the resulting offspring will probably have the disorder.

A study, published in the Journal of Cosmology examine the development of zebrafish embryos under conditions similar to the conditions of outer space. Research carried out by placing the embryos in the bioreactor is designed to simulate gravity conditions in space. The scientists then recorded the embryonic development.

After the eggs hatch, the scientists found that the bone supporting the gill change shape in some fish. A few months later, the number of fish that experienced abnormal increases. Scientists found the bones become bent at the base of the skull.

Research that has been done before also found something similar. However, the use of bireaktor criticized for being unable to mimic the conditions of outer space perfectly.

Articles study in the Journal of Cosmology is touching on topics that are considered taboo and NASA has never discussed before: sex in space. This topic arose after a plan to carry out the mission of sending humans to Mars.

In its publication in the journal Nature, on Tuesday (12/21/2010), a team of researchers from the Max Planck Institute for Evolutionary Anthropology (MPI EVA), led by Svante Paabo concluded that the fossils of early humans found in Siberia is a new species. They confirmed the differences with other early humans after successfully analyze 70 percent of nuclear DNA and finger bone fossil found in Denisova Cave.

Not only reveals the fact that humans now have a "brother" new, experimental studies have revealed another startling fact. Denisovans, the new types of early humans were, in fact he had crossed the globe to Asia and perform marriage with modern human activities in the area of Melanesia that had been spread in Papua New Guinea and some other Pacific region.

It was known after the researchers compared the DNA Denisovans with modern humans. The researchers say as many as 4-6 percent of the Melanesian people have the same DNA with DNA Denisovans. "We think this is a mistake at first, but this was real," said David Reich of Harvard University who was involved in this research.

With these results, Melanesian people said to have ancient genetic material from two early humans, Neanderthals and Denisovans. Previously, there has been research which revealed that all non-African humans have DNA from Neanderthals, Neanderthals consequences of the spread of population in the past.

Scenario the scientists say, Neanderthals and Denisovans derived from a common ancestor in Africa. Once separate but before spreading to Asia and Europe, Neanderthals interact and mate with modern humans. As a result, all non-African modern humans have genetic material from the Neanderthals.

Meanwhile, Denisovans spread to the east after the split into its own species. They met with a group of modern humans that move toward Melanesia approximately 45,000 years ago. Finally, the two kinds of people that also interact and mate, producing a combination of both genetic material that is now detected in this study.

However, the researchers did not state that Denisovans spread through Melanesia. "What we are saying is, Denisovans mating with Melanesian ancestors. Then, the population of Melanesia who are married fathers with Denisovans it moves toward Melanesia and Papua New Guinea," says Bence Viola, one anthropologist of the MPI EVA.

Reich's opinion, the interaction between modern humans Denisovans and perhaps more than expected. "They must have spread widely in Asia," said Reich. Population genetics research on the people of Asia Minor, according to Reich, can give clues about the distribution and interaction Denisovans.

Rick Potts, a scientist from the Smithsonian Institution who was not involved the research, said the study results may not refer to the genetic mix Denisovans and modern humans. According to him, it could be that there is genetic material in people Melanesia is an ancient genetic material is maintained and is lost in other human populations.

However, Potts has no other explanation of this phenomenon. He simply said, "I am very impressed with this publication. The article could take us far away and ponder. And, this is the result of good science."
