A Mysterious ancient city found in the middle of the sea

Historians and archaeologists are overwhelmed with the discovery of an ancient and mysterious city found in a remote place. The reason, the city was built in the middle of the ocean. Scientists themselves are surprised at this finding. As quoted from the Independent page on Tuesday, November 7, 2017, the settlement was finally found after nearly 100 years since the first search.

Interest in this mysterious island was initially triggered by a satellite image. Those satellite imagery has revealed the area of ​​the location. And now, this mysterious discovery becomes the subject of further research. Nan Madol's virtual image almost uninhabitable, located just off the main island of Pohnpei in Micronesia.

A surprising fact about this mysterious place, a settlement estimated to be built there in the 1st or 2nd century. Nan Madol itself has the meaning of 'intermediate space'. As quoted of the Independent again, this place is mentioned as 8 Wonders of the World by a number of European explorers. There are 97 geometric shaped blocks, separated by water channels that are not too wide.

Until this news is published, there is no comprehensive record to explain the basis or structure. But this mysterious place has also been discussed in 'What on Earth?' What on Earth? itself is a documentary series that tells the exploration of a number of researchers on various phenomena on our Earth.

These findings leave serious questions. In the documentary series, Patrick Hunt is an archaeologist wondering. "Why would someone build a city in the middle of the ocean ?, Why here, so far from another known civilization?" he said.

Mark McCoy of Southern Methodist University-who is leader of the research team on the mysterious island, later replied by commenting. McCoy said that the mysterious site is likely to be a burial place for elders. This site may also be a place for religious ceremonies and political power. This is because there is a stone wall that is about 7.6 meters high with a thickness of 5.2 meters in place.
Nan Madol is surrounded by a giant wall that is estimated to be composed of 250 million stones. (Picture from: http://bit.ly/2B2dC4P)
These findings sparked much speculation. Again, some compare this place with the island of Atlantis which is thought to have been lost under the sea. It was reported that locals near the mysterious place would not approach the empty 'haunted town'.

The first beginnings of this place began in the early part of the 20th century. When further explored, it was found a variety of surprising facts about Nan Madol. As quoted from the University of Oregon Anthropology Department, the city was formerly the capital of the Saudeleur dynasty until about 1628. The Saudeleur dynasty, the period of King Deleur was the first ruler to unite the inhabitants of Pohnpei Island.
The structure of the building in this place is built from a number of monolithic rocks weighing 5 to 50 tons. (Picture from: http://bit.ly/2B2dC4P)
Now, Nan Madol is located in Madelenihmw district, Micronesia Federation. Nan Madol is thought to have been the center of ceremonies and politics of the Saudeleur Dynasty. There is a unique story behind this city. Predicted, residents in this city number more than a thousand people. But it could be less than that.
Its population consists of a number of leaders and ordinary people. But what is surprising is the unfolding function of Nan Madol itself. Rulers have a way of organizing and controlling the number of people who are potentially their competitors. Strategy, the person is required to live in the city, not in their respective areas that are difficult to control.
"How do they arranged the giant rocks in the middle of an artificial land located in the middle of the sea?" It remains a mystery to this day. (Picture from: http://bit.ly/2B2dC4P)
Nan Madol is surrounded by a giant wall that is estimated to be composed of 250 million stones. The structure of the building in this place is built from a number of monolithic rocks weighing 5 to 50 tons. There is a possibility, the stones are imported from various islands that are around. Then the question is, "How do they arranged the giant rocks in the middle of an artificial land located in the middle of the sea?"

Archaeologists then try to reconstruct the construction of these stone buildings with various methods of transportation. However, no method works. Each method tried only to move a stone weighing not more than a few tons. Until now, can not be explained more details about the mysterious building structure in place. *** [EKA | FROM VARIOUS SOURCES | INDEPENDENT]

Nissan presents a GT-R that can be driven through a joystick

Nissan brings together the excitement of playing virtual games with reality through the Nissan GT-R/C, this is a dream car of the gamers that can be controlled completely through the DualShock®4 joystick. This is part of the celebration of the launch of the Gran Turismo Sport game in Europe on October 18, 2017 and commemorates 20 years of Nissan's involvement in the Gran Turismo game series.

These GT-R car can be controlled simply by using a DualShock®4 joystick. The vehicles with remote control is able to reach speeds up to 196 mph without anyone sitting behind the wheel. The speed of GT-R/C was tested by NISMO driver Jann Mardenborough at Silverstone. Jann controls the GT-R/C of the Robinson R44 Raven II helicopter cockpit, which already has a special permit to fly in low altitude.

Mardenborough is one of the most successful Nissan GT Academy winners, a revolutionary program from Nissan that seeks out and develops the gamers into real racing driver. Jann is the first racer to drive a GT-R/C because of his unrivaled talent at Gran Turismo and the real race.

"It's a great car and the first experience of a lifetime. The GT-R/C has merged my two worlds (virtual gaming and real racing world) in an unexpected way. The reaction of the car when controlled remotely is more interesting than I imagined. The designs by JLB are extraordinary in making everything react very well," says Jann Mardenborough.

"I'm happy to say all these challenges are passable, but this is also inseparable from Jann's unique capabilities that can control the vehicle in a very short time and produce a truly impressive lap times," he added.

Nissan has dedicated its best creativity and innovation to the racing world for over 80 years by combining technology and performance for competitive advantage. Since 2008, Nissan has also made the racing world more accessible to the public through the Nissan GT Academy, which can transform the game enthusiasts into professional drivers.

The GT-R/C was modified in the UK by JLB Design Ltd., by using the R35 V62011-specific engine that can be spewed the power up to 542 bhp of the same year when Jann Mardenborough won the Nissan GT Academy.

In the fastest lap recorded by Mardenborough (1:17:47), the average speed of the GT-R/C reaches 76 mph (122 kph) and the top speed at 131 mph (211 kph). Meanwhile, the average speed on the circuit with the lenghth of 1.6 mile/2.6 km is around 83 mph/134 kph.

The GT-R/C is equipped with four robots that control the car's steering, transmission, brake and gas lever. Meanwhile, there are six computers are installed to update the control up to 100 times per second. The steering position is also measured to 1/65,000 positions.

The DualShock®4 controls unmodified with a microcomputer that translates signals from buttons and joysticks to forward to the GT-R/C on-board system. This wireless operation has a main control range of up to one kilometer.

To help Mardenborough assess the speed of the vehicle in the corner, there's the Racelogic VBOX Motorsport sensor is installed to transmit speed data to the LCD screen in the helicopter cockpit.

The GT-R/C is also equipped with two independent safety systems that operate on different radio frequencies. This allows for two additional operators to brake the full ABS and shut down the engine if the primary operator loses its control.

"The GT-R/C has presented unique challenges and a number of our first engineering experiences. We must ensure effective robotic operation during acceleration/deceleration, as well as the power in sharp turns; provide real control and secure the car at all speeds; maintaining a strong relationship between the car and DualShock®4 with varying distances and with minimal conditions at the time of the robot in action," said James Brighton of the JLB Design Ltd.
In 2018, Nissan GT-R/C will be taken on the tour to primary and secondary schools in the UK to promote future careers in the fields of Science, Technology, Engineering and Mathematics. *** [EKA | FROM VARIOUS SOURCES | EVO]

This man's body suddenly bloated like a ballon, how could it be?

Having a work related to nature, sometimes unexpected things can happen suddenly. As the story of the fisherman follows, unexpectedly his whole body suddenly ballooned like a balloon after he dive for fish.
Peruvian fisherman named Alejandro Ramos Martinez gained nearly five stone after swimming up from a dive in the Pacific Ocean too quickly. (Picture from: http://dailym.ai/2xsIKMC)
Initially, a Peruvian fisherman named Alejandro Ramoz Martinez was doing his job as a fisherman and diving for fish. However, at that time Ramoz surfaced too quick to, then he was surprised because his body suddenly ballooned like a balloon.
Doctors are treating the unlucky fisherman but say they are unable to remove all the air. So far they have reduced the nitrogen in his body by 30 per cent. (Picture from: http://dailym.ai/2xsIKMC)
This strange thing just new felt by him as long as he work as a fisherman. According to doctors who treating him, this can be fatal. Ramoz is exposed to decompression effects because of its unprecedented nature. The sickness caused due to the many nitrogen that dissolves in his body, and it can also trigger brain damage.

5 mysteries of lost history is finally revealed

Some events in the past sometimes make us think that it is impossible. However, those impossible events and only based on the story, at the end were successfully revealed by the experts and scientists today.

Maybe you wonder how those mysteries of history are lost? Here are some lost historical mysteries that have been revealed.

1. Lost Army of Cambyses II
In 524 BC, the Persian King named Cambyses II sent his troops to invade the Egypt. There are more than 50,000 soldiers deployed to conquer it. However, all of a sudden all the soldiers vanished without a trace and become a legend since then.
According to the scientists the legend army of Cambyses II to invade Egypt was wiped out and vanished by an enormous sandstorm in the desert. (Picture from: http://bit.ly/2ynnvsi)
However, recently Angelo and Alfredo Castiglioni managed to find the remains of these legendary soldiers. This of course proves the hard work of these scientists for 13 years. Apparently, these soldiers not only disappeared, but they were killed in an enormous sandstorm.

2. Mysterious Bosham Head
The Bosham Head is one of the most debatable finds and turn out identifiable by using modern technology. Before, the Bosham Head was unnamed for more than two centuries because of its terrible condition.
Before the hi-tech study, little was known about the eroded 170 kg stone (left), which is twice as large as a human head, including who it was meant to depict. However,  now archaeologists believe it is the head of a statue of Emperor Trajan. A more complete and less weather-beaten bust is pictured right. (Picture from: http://dailym.ai/2wQKawg)
Recently, by using laser scanners have helped the scientists identify these 170-kilogram stone as one of the great statues of the Roman Emperor Trajan. And now, the statue is a tourist attraction in the port of Chichester and these Bosham head itself becomes one of the most important Roman heritage in Britain.

3. Mystery Of Death Valley's Walking Stones
It had been appalled the social media after the news of this walking stones appeared to the public. Everyone who sees the rocks in Death Valley, California whether in person or via the interwebs, have noticed a strange phenomenon that takes place with some of the Valley’s rocks- they seem to be moving across the valley floor.
The rocks in Racetrack Playa move slowly enough that you can’t see the movement happening, about 15 feet per minute, but the fact that they are actually moving is reconfirmed by the trails left behind in their wake. (Picture from: http://bit.ly/2fkWfU7)
There was no explanation of the phenomenon until Richard and James Norris proved that there was ice cubes formed around these stone in the winter. And when it melts, the rocks seemly begin to shift due to the wind blow.
Now, thanks to a lucky discovery made December 2014 by Richard and James Norris, we finally have an answer- weather phenomenon that surprisingly has much more in common with an arctic climate than a desert. (Picture from: http://bit.ly/2fkWfU7)

4. Mystery of Mary Celeste
Mary Celeste is a fairly famous ghost ship and was discovered in 1872 with no trace of crew nor any damage to the ship. Until a chemist named Dr. Andrea Sella did an experiment that could explain the phenomenon.

Noted there are about 1700 barrels of alcohol carried by the ship that could be easily make explosions and burns in the form a wall of fire when followed by a wave of cold air which not to leave a fire or soot. The crew can leave the ship and then die in the ocean.

5. Helicopter of Ancient Egyptian
The Abydos hieroglyphs in the temple of Osiris led to some discussions because of there were alleged symbols of helicopters, tanks, even a jet. There are many theories about the secret knowledge of the Ancient Egyptians.
The Abydos-Hieroglyph does not depict a Helicopter, Tank, or Jet. (Picture from: http://bit.ly/2xCYADX)
However, scientists managed to restore the original hieroglyphic symbols and prove that the helicopter and other symbols are mere manipulations by time. Apparently, our brain was deceives us to see the familiar forms in it. *** [EKA | FROM VARIOUS SOURCES |]

Turned out the Moon was 4.51 billion years old

According to scientists, it turns out the moon was older than previously thought, which is 4.51 billion years old. Thus the latest estimates, thanks to the rocks and soil samples collected by the astronauts of Apollo 14 on the moon.
The study has put the age of the Moon at at least 4.51 billion years — up to 140 million years older than previously thought, according to a new study of minerals called zircons brought back from the lunar body to the Earth by the Apollo 14 mission in 1971. (Picture from: http://adf.ly/1iDSow)
A team of researchers reported on Wednesday, January 11, 2017 that the moon formed within 60 million years of the birth of the solar system. The estimates range from 100 million the previous year, then to 200 million years after the creation of the solar system, instead of the 4.6 billion years ago.

Scientists are calculating the age of the moon by using the uranium-lead zircon metal fragments were extracted from samples of moon taken from the Apollo 14 missions. The pieces of zircon was very small, no bigger than a grain of sand.

"Size does not matter, because the fragments record an incredible information!" said the study's lead author Melanie Barboni from the University of California, Los Angeles. She added that the moon has "so many wonders key to understanding how our beautiful Earth formed and evolved."

Some of the eight samples of zircon has been used in a previous study, also conducted at UCLA. Barboni said that she was learning more zircon samples from the Apollo 14, but she expects it will not change the estimated age of the moon is around 4.51 billion year, at most only be 4.52 billion years old.
This is astronaut Alan B. Shepard Jr. on the moon in 1971 with the Apollo 14 mission. (Picture from: http://adf.ly/1iDSJF)
As we lall knew, the Apollo 14 astronauts, Alan Shepard and Edgar Mitchell collected approximately 41.73 kilograms and uses tubes to dig the ground while exploring the Fra Mauro highlands in February 1971. They walk twice on the moon, as a whole for nine hours on the lunar surface.

And this is the second major study of the moon on this week. Earlier, on Monday, Israeli scientists concluded that the moon may have formed from many mini moons. The moon, according to them, are not formed from the massive giant power hit and release the body parts of the Earth, but from a series of smaller collision may have created many moons eventually merge into one.

This giant force theory says that the result of the blow energy forming the moon lava ocean later becomes solid. This solidification age which is now confirmed by the Barboni and her team.

Barboni said like any process of formation of the moon, the result is the compaction of the moon as it is known today. "We finally determine the minimum age of the formation of the moon, however the process," she said. *** [EKA | FROM VARIOUS SOURCES | SCIENCEDAILY]

It turned out that dinosaurs became extinct because of the length of time hatching

The asteroid is not the only factor causing the extinction of dinosaurs 66 million years ago. Researchers also found that the length of time the hatching eggs are also influence at the extinction of the dinosaurs.

Recent research revealed that the dinosaur eggs take at least 6 months to hatch, much longer than previously thought that only 11-85 days. And according to a researcher from Florida State University named Gregory Erickson who studied two species of dinosaur, Protoceratops (dinosaur at the size of a sheep), as well as Hypacrosaurus (a big duck dinosaur).
(Pictured: Protoceratops andrewsi). Study reveals dinosaurs spent way longer in the egg than previously thought. (Picture from: http://adf.ly/1i9Tf8)
After scanning the jaws with CT Scan, the team extracted some teeth and analyze them with a high-resolution microscope. By using this technique allowing the researchers to identify the von Ebner lines, the growth lines owned by all animals.

"This is the development line of animals dental. Such a circle of trees. We can use this line to see the level of development of the dinosaur," Erickson said, as quoted of the Science Alert on January 3, 2017.

When analyzing, Erickson and his colleagues found that embryos of Protoceratops was 3 months old while Hypacrosaurus nearly 6 months.

"This means that dinosaurs had a slow progression. Three to six months allows the eggs are exposed to many risks, predators, drought and floods. Parent was potentially exposed to many risks," said Erickson.

The risk factors are more greater in extreme conditions, such as when the asteroid impact occurred. Under extreme conditions, the length of time hatching will increasingly hamper reproduction, thereby reducing survival.

In other words, the length of time hatching and catastrophic asteroid impact events is a combination that creates the extinction of the dinosaurs. This research was a preliminary study. And further research is needed to reveal whether other non avian dinosaurs are also experiencing a slow incubation period. *** [EKA | FROM VARIOUS SOURCES | SCIENCE ALERT]
