The mystery of Déjà vu finally explained

Most people have experienced déjà vu, fleeting sensations that make you feel never experienced an event, or passing through a place, but you never really experienced it or passed by. According to research, about two thirds of people have experienced déjà vu at least once in their lifetime.

The term of 'Déjà vu' was coined in 1876 by the French philosopher named Emile Boirac to describe a strong feeling that the experience you are experiencing now've ever experienced in the past. The 'déjà vu' word itself comes from the French meaning "ever felt or seen".

Déjà vu is a mystery because it is only fleeting and unpredictable, making it difficult to study. For years, scientists tried to unravel the explanations of what the causes of déjà vu. Recent research conducted by Akira O'Connor and colleagues at the University of St Andrews, England whose managed to find out what happens to the brain during déjà vu.

In the research, O'Connor and team are trying to induce a sensation of déjà vu in participants by instilling a false memory. The team then took brain scans of participants who experienced déjà vu using the fMRI (functional Magnetic Resonance Imaging). Initially, scientists thought that the brain areas involved with memory management, such as the hippocampus, will be active as long as this phenomenon occurs, but it is not. The team actually found the frontal lobe, the area of ​​the brain involved in decision-making becomes more active.

O'Connor said the frontal lobe checked entire our memory, and transmit a signal if there is a memory error, the conflict between the things that has really we have experienced and the things we think we have already experienced.

"That suggests the possibility of some conflict decision-making happens in the brain during déjà vu occurs," said Stefan Kohler of the University of Western Ontario in Canada.

This discovery also shows that déjà vu was a sign that the memory checking system of brain working properly. It fits in with what is called the effects of age on memory, because déjà vu is more common occurs in people of young age and rarely in old people, since memory began to decline. 

"Scarcity of déjà vu at the old age may show a decrease in the general checking system, so that memory errors tend to be overlooked," said O'Connor.

However, it does not mean that people who have never experienced déjà vu was in trouble with their memory checking system. O'Connor said, "It may be that people who do not experience déjà vu have a better memory system, because if there's no memory error occurs on the brain, there's nothing will be triggered the déjà vu."

Until now, scientists could not confirm whether déjà vu have health benefits. "It could be, the déjà vu experiences make people more careful, because they became not too much trust in their memory, but the evidence for that yet," said Kohler. *** [EKA | FROM VARIOUS SOURCES | NEWSCIENTIST]

For the swing arm, it was made custom and looks more luxurious. In addition to its glossy as well as design. "That's imitated from HD, and its shape customized like this and proved to make it not too difficult," said the owner of the workshop located on Jl. Ciputat Raya No. 15, South Jakarta. The most distinctive characteristic of this design is in the shape of the curve. It could say all the things associated with the wheels and suspensions looks clean and sleek.

"Because its body is made of contradictions. Given a touch of black and red colors that are clearly visible," he added. Indeed, the homemade body parts are not too much. Only custom made fuel tank, and the minimalist engine cover are made using just a little of galvanized plate

What if the Lamborghini Urus has six-wheels?

Lamborghini is one of the renowned Italian supercar brand is a step would give birth to SUVs for the first time in history. The fans have gone crazy with it, and even now their dreams have been even further.

As shown on the Urus rendering images were uploaded at the Lamborghini enthusiast site, lambocars.com. The name of the first Lamborghini's SUV shown in the off-road terrain conqueror style completed with six wheels. The concept, Urus made like the Mercedes-Benz G63 AMG 6X6.

May be this Lamborghini Urus 6X6 a little bit extreme. But if the German can, why can't the Italian? (Picture from: http://adf.ly/1dbs2D)

Face of Urus much like the concept version that had shown at the Beijing Auto Show 2012, with the additional such as more higher ground clearance, rear bed with frame bar which strengthens the integrity of the chassis and of course 6 big-wheels to traverse various off-road terrains.

Obviously there is a fundamental difference between the Mercedes with Lamborghini. The German brand has long had the division of commercial car and performance that moves independently to produce special vehicles.

For example, the G63 AMG 6X6 is designed taken based of the G-Class. By two additional wheels making it very steady used to conquer various off-road surfaces, especially supported by 5.5L V8 engine with the power up to 540 hp and torque of 760 Nm.

The Urus 6X6 shape may be too extreme for Lamborghini, but who would have thought in the future would come true. The plan, the Urus will be mass produced next 2018. *** [EKA | FROM VARIOUS SOURCES | LAMBOCARS.COM | CARSCOOPS]

These chips will replace animals as the research objects

The use of animals as a research object has indeed been done long ago. However, researchers are now setting up a chip-based highly sophisticated computer algorithms to replace animals as research objects.

Before a drug or various medical supplies for human use, a long series of research and testing processes, certainly has been done to ensure that the drugs used truly safe for humans. To these purposes, many animals are used in the lab to follow a series of tests of the researchers.

We’re getting closer than ever to replacing animal testing with computer chips. (Picture from: http://adf.ly/1dbq9V)

Seeing this, the US government encourages its researchers to replace animals with a device resembling a human body, in order to be used as experimental material. It creates the idea to make this chip.

As quoted of ScienceAlert, lead researcher Linda Griffith of the Massachusetts Institute of Technology (MIT), said her team has received millions of funding from the Defense Advanced Research Projects Agency (DARPA) and the National Institutes of Health to develop these chips.

These chips were mostly made from synthetic materials such as polymers, currently still in a period of further research, in order to ensure that the chip is actually similar to the tissues in the human body.

"These chips are designed to mimic the function of specific organ systems representing a broad spectrum of human tissues, including the circulatory, endocrine, gastrointestinal, immune, nervous, reproductive, respiratory and urinary system," said one of the researchers of this chip.. *** [EKA | FROM VARIOUS SOURCES | SCIENCE ALERT]

Mysterious signals emanating from space

A surge radio signals coming from a Sun-like star has attracted the attention of astronomers. The signal is thought to have come from a star called HD 164595 in the constellation of Hercules, which is about 95 light years from the Earth.

Scientists estimate the signal is the result of natural phenomena such as microlensing, in which the star's gravity becomes stronger and focusing the signals elsewhere.

However, astronomers have also been asked for SETI (Search for Extraterrestrial Intelligence) for a closer look at whether the radio signals were a message from extraterrestrial beings.

As quoted by the Daily Mail on Tuesday, August 30, 2016, SETI track the HD 164595 using the Allen Telescope Array in northern California and Boquete Optical SETI Observatory, in Panama.

Scientists suggest the spike (pictured) may be the result of a natural phenomenon, such as 'microlensing', in which the star's gravity strengthens and focus signals from farther away. (Picture from: http://adf.ly/1da2SW)

According to the explanation by Paul Gilster in Centauri Dreams, the signal was first detected on May 15, 2015 by the RATAN-600 radio telescope in Zelenchukskaya, Russia.

HD 164595 attract the attention of scientists because it is like the sun, at least has one Neptune-sized warm planet known orbiting. But they said it was likely there are other planets that have not been detected. The average temperature of HD 164595 is 12 Kelvin hotter and aged 100 million years younger than the Sun.

"No one is claiming that's an act of the extraterrestrial civilization, but it deserves to be studied further," said Gilster.

"The researchers said that, if it comes from an isotropic flare, is likely only come from Type II Kardashev civilization."

A spike in radio signals coming from the direction of a sun-like star, HD 164595, is being followed up by alien-hunting telescopes. SETI is using the Allen Telescope Array (pictured) in northern California and the Boquete Optical SETI Observatory in Panama to confirm the data. (Picture from: http://adf.ly/1da2SW)

"(But) if it is a narrow signal that focuses on our solar system, the possibility of a power available to Type I Kardashev civilization," he added.

Kardashev scale is a way to measure the technological sophistication of an alien civilization is based on the energy used. According to the makers of the scale, Nikolai Kardashev, there are three types of the alien civilizations.

Type I civilization consists of species that are able to utilize all the available energy of the nearest star, collect, and store it to meet the needs of its population. And Type II civilization much more advanced and can utilize all their star power. While the civilization of type III, a species that has been able to control everything related to energy.

Paul Gilster of the Tau Zero Foundation, which conducts research interstellar say, if the signal was artificial, then it could be derived from a more advanced civilization than human - or is in Kardashev scale entry into the Type II.

Currently, humans are around Type I - where civilization is able to utilize all the available energy, including solar, wind, earthquakes, and other fuels. Meanwhile, Type II has been able to utilize the whole of the energy emitted by the star, which powers billions of watts.

In a statement, Seth Shostak, the SETI Institute's senior astronomer claimed to have no clue where the civilization that seeks to give the 'messages' to us. "It is difficult to understand why someone would want to target our solar system with a strong signal," he said further, as quoted by CNN.

"It's a little confusing, because Russia has found this signals a year ago, but do not let other people know," said a senior astronomer at the SETI Institute.

"The signal may be genuine, but I suspect that it is not extraterrestrial beings. There is another possibility that such a broad signal caused by the natural disruption (or even terrestrial interference)."

Researchers who found the signal at the Special Astrophysical Observatory, Russian Academy of Science said that required further observations to HD 164595. The discovery of the signal will be discussed at the International Astronautical Congress held in Mexico in September 2016. *** [EKA | FROM VARIOUS SOURCES | DAILY MAIL]
