SCIENTISTS FINALLY explain how the pyramids were built EGYPT

A new study shows that the ancient Egyptians who built the pyramids, may have moved the massive stone blocks through the sand desert watering, leaving the soil consistently to pull heavy objects. Some physicists at the University of Amsterdam investigated the necessary strength to pull heavy objects on a giant sleigh on the desert sand, and found that moistening the sand in front reduces friction on the sled, making it easier to carry. The results help to answer one of the most enduring mysteries of history, as the Egyptians were able to accomplish the seemingly impossible task of building the famous pyramids? To make their discovery, the researchers took painted murals in the ancient tomb of Djehutihotep, which in 1900 BC describes 172 men carrying a huge statue using ropes attached to a sled. In the drawing, a person can be seen standing in front of the sled, pouring water on the sand, said lead study author Daniel Bonn, a physics professor at the University of Amsterdam. 

Each pyramid block weighs about 2.5 tons.

About where to get water ? Many believe that the nearest source for this would be the Nile Bonn and his colleagues built miniature sleds and tried to pull heavy objects through sand trays. When the researchers drag sleds on the dry sand, they noted that they would need ever more power to pull them . Addition of water in the sand, however, the sledges were able to slide easily over the surface. This is because the water creates a firm, hard ground.

90 % OF PEOPLE can not see A PICTURE THAT ANIMAL

An advertising campaign created by an international agency for the WWF, carries the message about the preservation of animals on Earth, however, which is viralizando, was a picture "barely recognizable" to 90% of people. The campaign draws attention to the preservation of animal species, in which the focus is the image in question: According to the IUCN (International Union for Conservation of Nature and the International Union for Conservation of Nature) the animal (we will not speak the name not to spoil the joke) suffers a red alert with the sum of 2,500 adults in the wild. Although there is a hope that we humans can help the survival of this species is still uncertainty, ie it is an endangered species. The animal, is currently in the red zone of endangered species. * Of course we work with a joke about 90%, but avoided comment on what species is when discovering share, sending to your friends and colleagues asking if they can see.

RESEARCHERS DISCOVER WOLF 1061C A POTENTIALLY HABITABLE PLANET EARTH CLOSER

Australian researchers have found in Chile, a nearby planet Earth that could potentially be habitable. The discovery was announced today (12/17/2015). Called Wolf 1061c, is about 14 light years from Earth and is part of three planets orbiting the dwarf star Wolf 1061, and are larger than the Earth (1.4 / 4.3 / 5.2 times the Earth) . "It's fascinating to see the immensity and think you are so close to us, is a close neighbor and could host a habitable planet," said Duncan Wright, who led the research. Among the three, one of them (the largest) is out of a habitable area, and another (the lowest) too close to the star, and in the middle (the middle) in an area called the "Goldilocks" is the Wolf 1061c, which brings together ideal conditions to take life as it is not too hot and not too cold too, and may even be water and even life. Remember that there is life, it is not necessarily the existence of human and yes, plants or live microorganisms that could possibly evolve, as it was on Earth billions of years. The discovery was published in the renowned magazine "The Astrophysical Journal Letters" and was carried out with the telescope of the European Southern Observatory in La Silla, Chile. There are hundreds of rocky planets like Earth in the universe, but most are hundreds or even thousands of light years from Earth, thus hindering research. Today, what we have is the closest Gliesse 667Cc, there are 22 light years away and orbits its star lasts 28 days. So this was another step and we hope that more planets like Wolf 1061c and Gliesse 667Cc be found close to the Earth.

Separated two images you can follow the reasoning of the Wolf 1061c

They were walking ON A FROZEN LAKE WHEN spotted something bizarre

There are a lot of people who believe in extraterrestrial life (including me) . Most have little evidence to reinforce their beliefs , which always makes these people seem crazy . 

But what these guys found in a lake is enough to make even the most skeptical person to believe there might be something else out there . Take a look at these things and see if you have any plausible explanation for it there.

Watch this video from the frozen lake and tell me what you thin kis: 

What is this? Give me a reasonable explanation , because I need one. I really need to believe that these things are not alien eggs, if not, I will not be able to sleep again.

TUVALU MAY BE ABOUT TO MAP disappear

One of the smallest countries in the world , and perhaps one of the nicest , can be extinguished map. To prevent the territory disappear underwater, the government filed a request for help in the EU. Enele Sopoaga , Prime Minister of the country was personally at the headquarters in Brussels for support that helps .

 With 26 km2 , Tuvalu is part of a small Polynesian island , and has only 10,000 inhabitants. The highest point of the country is two meters above sea level , and because of global warming is the country with extreme risk that in a few years the short country literally map. 

With increasing temperature on the earth , the melting of poles increases, and consequently also the ocean volume , thereby to increase its sea level. And an increase of 2 degrees Celsius in the average temperature ever would cause Tuvalu map short .

NASA shows evidence of the existence of liquid water on Mars and current

Mars is a planet that does not go out of focus of science, researchers and scientists from NASA. And this is due to the mysteries that the reddish region hides and even controversies that have been discovered there. Baptized water wires " recurring slope lines," NASA said it had discovered liquid salt water on the slopes of some mountains on Mars. Second images of a spacecraft in orbit under the red planet, the MRO ( Mars Reconnaissance Orbiter ) , beds of about 100 meters long and less than 5 meters wide were found on the red planet . According to the head of the Mars exploration program at NASA , Michael Meyer , these lines " are dark bands that form in late spring , grow in summer and disappear in the fall ."

These lines were old friends of the American space agency, but were not confirmed because of the poor quality in the resolution of the images. As shown in the pictures in high resolution, stretch marks appear next to Hale crater slopes during the period of hot weather and if stretch , then immediately disappear during the colder seasons . In an interview with the journal Nature Geoscience , Lujendra Ojha , of the Georgia Institute of Technology , said "Whether there is liquid water on the Martian surface is central to understanding the water cycle and the potential for the existence of life on Mars "

NASA says the next step is to work in partnership with Russia and send another probe to investigate the interior of the red planet. The forecast is sending probe in 2016 and already in 2018 send another probe to analyze the organic matter. Two years later, a mission will be to collect samples of what is hidden beneath the surface and there is the possibility of sending astronauts to Mars.

How is the vision of a Dog ?

A common question is whether the dog sees in color or black and white and the truth is that they have the ability to see colors, but not in the same way we do. For dogs, the green, yellow, orange and red have no difference. It's kind of blindness to these colors. But the dog can differentiate violet, blue and green. Many scholars believe that the dog sees a yellow tone when you look at the red, green and yellow, and it would be exactly why he could not distinguish it.

 In short, dogs see colors, but with fewer shades and less precision than us, we can distinguish about 10 million different colors and combinations On the other hand, you have the ability to perceive so many shades of gray that is almost impossible to fully test this talent, because of our own limitations. The most widely accepted explanation for this phenomenon is that the old canids, ancestors of our dogs, were night hunters and differentiation of gray tones was far more important than color vision.

 And like all predators, dogs quickly identify moving objects. This was fundamental for their good performance in the hunt. Today there are still many races to "hunt with the vision" as greyhounds, whippets and almost all lebréis. This is a factor of the most developed in canine vision and can, in the open, to distinguish a cat-sized objects moving at nearly 1,000 m.

 On the other hand can take to see a stationary object that you try to show to 1 meter away. So it's easier to get the attention of your friend with movements and signals. Therefore we can say that dogs see no better or worse than us, just do it in a different way.

Extraordinary facts about dreams

• Blind people also dream People who become blind after birth can see images in dreams. People who are born blind do not see anything, but have dreams equally vivid involving their other senses: hearing, smell, touch and emotions. It is difficult for sighted people imagine, but the the need of dreams for the body is so strong that the blind can virtually handle all situations that dream. 
• You forget 90% of your dreams After five minutes awake half the dream has already been forgotten. In 10m, 90% is gone. The famous poet Samuel Taylor Coleridge woke up one morning after a fantastic dream (likely opium induced) and began to describe his "vision in a dream," which is one of the most famous English poems: Kubla Khan. After having written 54 lines he was interrupted by an unwanted visitor. Samuel returned to his poem but could not remember the rest of your dream. The poem was never completed.
•  Everyone dreams Except for a few people with extreme psychological disorders all the rest of us dreams. Dreams prevent psychosis In a recent sleep study, students who were awakened at the beginning of each dream, yet could sleep your eight hours of sleep. All experienced difficulty concentrating, irritability, hallucinations and signs of psychosis after only three days. When they were finally allowed to sleep during the REM (Rapid Eye Movement in English or rapid eye movement, is the physiological signal that started dreaming during sleep), their brains made up for lost time greatly increasing the carried sleeping percentage the REM stage.
•  We dream only about what we know Our dreams are frequently full of strangers who desenpenham certain roles. Did you know that your mind is not making these faces? They are real faces of people you saw during your life, but can not remember. There is a science that says that dreams are manipulated into reality by own individual spirit, as a kind of communication.
• Not everyone dreams in color There are people with normal vision (12%) who dream in black and white only . The remaining dreams in color . There are also common themes in dreams , which are situations relating to school, being chased , try to run and still move slowly , sexual experience , falling , falling behind , a living person currently being dead , teeth falling out , flying, failures an exam or car accident. It is unknown whether the impact of a dream relating to violence or death is more emotionally charged for a person who dreams in color or those who dream in black and white.

What are the first and the last countries in the world to enter the new year?

The New Year is the most anticipated holiday in several countries. The date marks the renewal of faith, hope, love and determination. This is a magical and special moment, in which people have the chance to make new resolutions and goals. Although considered day of universal brotherhood, the new year comes at different times for some countries. Some nations celebrate the New Year first, and others have to wait to celebrate the date, all because of the time zones. 

In general, the first celebrating the new year is Antarctica. Another area where the new year arrives faster is the easternmost island of Kiribati, also known as Carolina Island, located in Oceania. Then the list of countries to first celebrate the turn of the year, we Samoa, a country near French Polynesia.

The new year comes quickly to these regions because they are geographically located in areas with zones earliest times . Moving from one year to the next takes place the first call on International Date Line (LID ) , which is in the Pacific Ocean west of Hawaii. In contrast, Honolulu , Hawaii, is the last region of the world to commemorate the date .

And if countries are different when entering the new year, they also differ in the types of celebration. In Brazil, the traditions are jumping waves, eat lentils and wear white clothes. In China , people offer food to gods . In Japan, the cleaning ceremony takes place in homes. In France , people sipping champagne . In the United States , people face the bitter cold of winter and go to Time Square in New York , to accompany the countdown.

The nine largest craters created by man

There are several craters in the world , many of them caused by man , mainly in mining activities. The largest craters created by man in the earth's crust can be seen in the open in countries like Russia, the United States, Canada , Chile , among others.

These craters cause major environmental concern , because it directly affects the soil , groundwater , rivers , fauna and human life . The environmental impact is extreme .

Meet the 9 largest craters caused by man:

1 - Mir mine - the world's navel call , the crater is huge , with about 525 meters deep and 1,200 meters wide. The crater is in Siberia , in the town of Mirny , and is used to extract diamonds. The hole is so large that it disrupts air traffic in the region . The Mir was extensively explored between the years 1957 and 2001 .

2 - Chuquicamata - This open pit mine is the largest in Chile. It was once considered the world's largest operating mine producing 29 million tons of copper . The crater is 4.3 km in length and 850 meters deep.

3 - Berkeley Pit - This ancient copper mine operated from 1955 to 1982. The crater is 270 meters deep. 

4 - Bingham Canyon - The mine is located in Salt Lake City, Utah ( USA). It is the deepest open pit mine in the world , with a thousand meters deep and 4,000 meters wide.

5 - Derweze - This crater drilling rig put the lives of many people in danger. The Derweze village became vacant .

6 - Udachnaya - This Russian mine was discovered in 1955. It is considered the third largest in depth, about 600 meters.

7 - Diavik - This Canadian mine was discovered in 1992 to use open-pit mining .

8 - Grasberg - The Papua mine in Indonesia , is the largest gold exploration in the world. It has come to produce 610.8 tons of copper as well as gold and silver.

9 - Serra Pelada - This mine is located in Pará, Brazil . The crater is 100 meters deep, and was used for the exploration of precious metals like gold, platinum and palladium.

How many sheep do you see in this picture ?

The sheep, in the order and scale of animals, is far from being a predator. They are animals that have no camouflage, and hardly escape when under attack. Ma a curious and interesting fact caught the attention of the Canadian farmer Liezel when Kennedy took care to be herd , realized that his 500 sheep were gone. Desperate, Liezel got into his car and was looking for them. 

After walking a bit , Liezel noted that the stains that appeared to land in the midst of so much snow , were actually his sheep 

Liezel shared what happened on social networks to your friends who also fell in the " sip of view " of the sheep , proving that he was not crazy .

And you , what do you think of the pictures ? Also lose the sheep ?

Hayabusa 2 captures stunning image of Earth and the Moon

If you ever wondered how the Earth and Moon can be a little distance ? Further noting here on Earth, but the average distance of the Earth to the Moon is 384,403 km on . It seems close, but a new photo clearly shows how the distance is too great. The record , made by the Japan Aerospace Exploration Agency with Hayabusa 2 , managed to capture the two bodies into a single image . 

Recently registered on 26 November, the image was recorded by optical telephoto navigation camera ( ONC -T) , and shows more of the Earth's eastern hemisphere , and details how the moon is orbiting as if suspended by a huge rope heavenly. Hayabusa 2 was launched on December 3, 2014 , and is currently carrying out an Earth swing before heading out to an asteroid called Ryugu , which will collect samples that the researchers hope to provide clues about the "origin and evolution " of the solar system.

Check out the picture of the Hayabusa 2

About Ryugu Ryugu is a C-type asteroid, so named because of the large amounts of carbon-containing molecules. Other types include asteroids are predominantly rocky. Ryugu is considered important for researchers, since it is home to organic minerals and hydrated - which means that contain water, and are seen as one that may contain clues about the origins of life on Earth, as well as the structure and the formation of first components of the solar system.

 Yasuhiko Takagi - who has been working on the project said, "minerals and seawater that form the Earth as well as materials for life are believed to be strongly connected in a primitive solar nebula in the early solar system. Hopefully clarify the origin of life by analyzing samples acquired a primordial celestial body ". Name Selection Asteroid 1999 JU3 / Target Asteroid Explorer "Hayabusa2" The asteroid 1999 JU3, Target Asteroid Explorer "Hayabusa2", was named "Ryugu". The Agency of Japan Aerospace Exploration (JAXA) carried out a campaign of appointment between July 22 and August 31, 2015. The result of careful study of the names proposed by the jury was Ryugu; In the Japanese ancient history "Urashima Taro", the main character, Urashima Taro, brought back a Dragon Palace coffin, or Ryugu Castle.

 The Hayabusa2 will also bring back a capsule with samples, so the theme of "bringing back a treasure" is common, getting the name of Ryugu.

Our sun can release solar flares thousand times more than normal

New research suggests our sun , has the ability to produce bursts of energy and radiation 1,000 times more powerful than regular solar flares . If true, this has implications for how we would protect us from potentially catastrophic solar storms . 

The study, to be published in Astrophysical Journal Letters , was led by scientists at the University of Warwick. They looked at a distant binary star called KIC 9655129 in the Milky Way , which is known to have solar flares . 

These massive explosions were first found in the 1970s , it was thought by produced by a process of regular solar flares . However , research shows that the physics of solar flares of KIC 9655129 , is noticeably almost periodic , appearing constantly on the Kepler space telescope , and are similar to eruptions in lower expression of our sun .

And the study shows that for almost the same structure of both , it would be possible to take place in our sun. But Pugh , who led the research, said that the chances of this happening soon was " incredibly unlikely " , although it is possible every 600 years , according to other research. 

And there is evidence for the producers of solar flares from our sun in the past. "Looking at the Arctic ice cores , scientists have found certain " bombing " of radiation, suggesting that this is due to a large solar flare in 700 AD and 900 AD ," said Pugh . " It was not too long ago ."

Understand the risks of solar flares

A solar flare pointed toward Earth can cause damage to satellites and even astronauts in orbit, with an energy equivalent to a pump 100 million megatons . We have a variety of space weather prediction centers around the world to help mitigate the effects , such as shutting down satellites, but if a storm is powerful enough , then the radiation may be too much even for the most resistant to it.

Solar explosions seem to be like a sunspot . In some stars that can cover almost 50 percent of the star's surface. In the sun , according to Pugh , it might be one-eighth of a quarter of its surface , although this is a very high estimate. These active regions may persist for days , releasing several solar flares , seemingly at random , but within that timescale . Then there would be some indication when it may be about to occur , and we could do our best to reduce its effects if it was pointed at us .

Scientists solve puzzle of lights Alien megastructure

In recent weeks, researchers around the world were literally lost with a mysterious light from a star, located in the depths of the universe. That has taken the internet and became known as the alien Megastructure. However, it was not what we thought. 

The SETI Institute (Institute for extraterrestrial intelligence that seeks) recorded in the solar system KIC 8462852 interference in reading the reports they receive. In order to understand more about the reports received, the lizes waves is uniform and constant, if we were using a line she would be continuous and infinite, but in a few days, which was a continuous line began exhibiting "failures" and negative peaks, which represents interference. 

Intrigued by the records of KIC 8462852 system, and using data from NASA's Spitzer Space Telescope, could then solve the mystery, finding evidence that interference were carried out by a swarm of comets. The study, led by Massimo Marengo of Iowa State University, Ames, was accepted for publication in Astrophysical Journal Letters. However, according to Marengo, more observations are needed to help solve the case of KIC 8462852. "This is a very strange star and we will keep an eye," he said.

Understand how the readings of the lights are made ;

KIC 8462852 , located 1480 years light away , was monitored by the Kepler Space Telescope for over four years starting in 2009. And as a planet or comet passing in front of the light from a star , makes the light dim and back , like a beacon , and Kepler can captured these inconsistencies .

Amazing pictures of a deserted island in Japan

These stunning photos reveal the forgotten and decaying beauty of a once prosperous island city in Japan. The city is called Gunkanjima and is about 15 kilometers south of Nagasaki. The place is well known as a forbidden treasure of urban development in ruins. 

Although the safety of the island is very strict , apparently not hard enough to keep the Australian photographer, Shane Thoms off the island. And we are happy that he has found a way to enter, because their ghost town of photos are absolutely mesmerizing . 

The city of Gunkanjima came years ago as a housing project for people working in the coal mine there. But when the mine was closed in 1974 , the city was abandoned and the buildings left vacant and forgotten. Decades passed and the city began to rot and decay , slowly taking a post- apocalyptic appearance now has

In 2009, the island was declared a UNESCO world heritage site, which means that security has become intense. Now, visitors are only allowed to stay on the island for 30 minutes, and even then, they are required to stay within a special fenced in area. But Shane Thoms wanted to see more, so he planned to sneak into the island with some friends to spend the night and shoot the concrete deteriorating. The boys were able to reach the island by boat with a guide. The fisherman left them on the island and they began their stealthy exploration of the forgotten city. "Forty years of no maintenance had taken its toll, with many stairs and hallways falling apart" Thoms wrote on his website. "After a while I got completely lost in an impressive maze of small alleys of decayed concrete and narrow staircases covered with moss." They watched the sunset from a roof and pitched among the ruins that night. The next morning, they explored a little further and continued taking pictures until the fishing boat came to pick them up again.
