According to reliable sources, U.S. researchers said in a recent study, the water content inside the moon is likely to exceed the previously estimated 100 times. This finding may undermine some of the theories about the origin of the moon.

Origin of the current international common theory about the moon There are 4: “split theory ” that the moon was split from a piece of the earth; “capture theory ” that the moon of the planet is an independent, near the Earth captured by Earth’s gravity; “Homology theory “that the earth and the moon at the same time by the same cloud of matter together to form; ” giant impact theory “that the earth is still in the molten state, a large object hit the earth, projectile out of the material was placed in Earth orbit, and gradually Aggregate to form the moon.

Case – Western Reserve University, Carnegie Science Institute and Brown University researchers have used ion microprobe analysis, analysis of the Apollo 17 spacecraft brought back from the moon formed about 3.7 billion years ago, the Moon lava samples. This technique can measure very low water content, and high precision. The researchers drew the sample components in the distribution of water and found that they show the water content than the earlier estimates based on more than 100 times higher than the water content. They also found a higher than expected levels of fluorine, sulfur and chlorine.

“These samples provide the best moisture content within the viewing window, the moon, ” Case – Western Reserve University professor of geology at James Fanao Coleman said, “we know from the abundance of water, the moon and the Earth within it seems Very similar to the internal. ”

The study will be published in the United States, 27 new issue of “Science”magazine. The researchers believe that research results support the origin of the Moon “homologous said, ” and questioned the “big collision, said” certain elements of the latter “need to reassess. ”

Oxford University study showed that the rare occurrence of severe weather may be frequent

Latest Information, Oxford University scientists have studied the draw, due to continued global warming, similar to the 2011, 2010, Pakistan and Australia, the rare occurrence of floods and other extreme weather will show an upward trend in the frequency, the earth’s climate will become increasingly worse .

Scientists pointed out that the El Nino phenomenon is the main cause of global warming. Study found that, from the Pliocene, the El Nino phenomenon has been affecting the global climate, carbon dioxide levels in the Pliocene and present fairly, but the global average temperature higher than the current 2 ~ 3 ℃, 21 century, the Earth human is likely to return to the climatic conditions New World.

Nick Scott, chief expert of Earth Sciences, said: “We know through previous studies, current climate models and is very similar to the Pliocene, these extreme weather events are very typical of El Nino. ”

Study revealed the Pliocene period of El Nino and La Nina phenomena fluctuation, the scientists hope the El Nino phenomenon can long dominated the Pacific, as generally believed that the El Nino phenomenon caused by the Pacific warming will reduce the extreme weather, but research has found that the next El Nino and La Nina phenomenon back and forth Fluctuations in the frequency will increase, or be more natural disasters.

El Nino refers to the equatorial Pacific ocean and atmosphere with the interaction out of balance, leading to changes in weather patterns throughout the world, the eastern and central tropical Pacific Ocean temperature anomaly to continue warming, some regions of drought, flooding in some areas. El Nino and La Nina is just the opposite, that is cold equatorial Pacific sea surface temperature anomaly field reduced the phenomenon, also known as “cold event. ”

Experts said that protecting the planet needs more and more worthy of attention, the global climate continues to deteriorate, eventually will give us a devastating impact, care of the earth, that every country or even that everyone should do the obligation.

Latest news, scientists said on May 18, breaking the brain and visual signal that mentalimages can show ”Reading the effort”to become a reality a step forward.

British researchers at the University of Glasgow to the six volunteers showed somefacial photos, these photos look different, such as pleasure, fear and surprise. In a series of tests, some of these pictures were randomly obscured, for example, can only see the eyes or mouth. Participants judged the pictures and then let the characters facial expressions, at the same time, the researchers installed volunteers scalp electrodes to detect their brain waves.

Scientists found that, according to the site to see, test participants brain waves change dramatically. Frequency is 12 Hz ”β” wave carrying the information about the eye, and the frequency of 4 Hz ”θ (theta)” is carried by waves and mouth-related information.Responsible for the study, Professor Philip • Sharansky Burns said: “This is likeunlocking a scrambled TV channel. At first, we can find the signal, but can not see thecontent. Now that we have been able to see the content. brain How to decode visual information, let us identify the facial features and feel, this issue has been a mystery. ”

Ski Burns said: “Although in the implementation of special tasks, we can find specificparts of the brain’s electrical activity, but we do not know of these brain waves to carrywhat information. “ Now we are looking for ways brain waves break so that Identify the information they carry. He said the study shows how the brain to adjust to different brainwave patterns, decoding of different visual features. ”It’s a bit like radio waves of different frequencies of radio decoding. This man-machine interface research and       development work has enormous significance. “Of course, I think not only in human-computer interface research and development of great significance, in terms of the police solve the case I believe there are unprecedented Help.

This is not the world’s natural heritage, not a world geological park, not included in the United States means the operator can not hunchback country park system, where subordinate to the U.S. Bureau of territory to govern, even our travel area are often said not really, it is only the United States many natural A maintenance area, people give it very image of a very popular name: the waves Valley.

Dan Yanjing like this started in the one hundred million nine hundred million years ago, Jurassic, until thirty years ago, until somebody found the American dream has been to encourage those who had disdain for those who like several photographers crowded the local, where deserted to Where to run, the final cliff in Arizona’s Paria Canyon scarlet found this a good local.

One, the United States to cause infarction, enjoy high scientific value, this scarcity of capital property to the waves are not Google do not want to become famous, people across the American landscape, or across the Atlantic Ocean, Cheng Ping Yang, came to worship. At this time, U.S. authorities presented, the authorities said that this is the Earth’s wealth, the wealth of all mankind, we have to do is to maintain, maintenance, and then maintain them as her inability to less than a generation or two toy indulgence, and To be left to future generations.
