Facebook changing our brains?

People with a long list of friends on Facebook have larger and denser structure in the three regions of the brain than those with only a few online friends.

Scientists are investigating, but have not yet figure out whether part of the brain responsible for social life that affects people who spend a lot of time on Facebook have more friends, or is used frequently, and social networks lead to changes in the brain.

By studying the brain's Facebook researchers found that people with a longer list of friends on this network have larger and denser structure in the three regions of the brain than those with only a few online friends.

It is the upper temporal lobe and the middle temporal gyrus, which are associated with social perception as the perception of another's look or facial expression, and entorinal cortex which in turn is associated with remembering faces and names.

- The question is whether the size of the "social" part of the brain encourages people to have more friends on Facebook or the area is subject to change due to frequent use of social networks - says lead researcher Geraint Rees, neurologist and professor at University College London, adding that it will be more studies are needed to reach the right answer.

In the past, and Susan Greenfield, an Oxford which deals with scientific research in the field of neurology, causing controversies by claiming that the human mind in the 21 clear podetinjiti century, to be incapacitated for a longer concentration and empathy, will tend to sensationalism and will have a deluded sense of identity.

Soon the new look of Gmail?

Video is presented in which a new design of Gmail mistakenly got on YouTube and then disappeared with him.

Meanwhile, Google is the announcement came that it was true that the new Gmail stores, but that was not supposed to see this video. At least not yet.

See the "controversial" video!



When you already are, in the above video we could hear about the redesign and much clearer view of Gmail, the function of screen size and improve search and filtering e-mails, as well as some of the innovations.

Alma telescope, seeking the origin of the universe

One of the largest scientific enterprise 21st century, Alma telescope in the desert Atacama plateau in Chile, started its work. The task of the largest and most complex ever field a radio telescope to investigate and study the processes that occurred several hundred million years after the universe when the first stars began to shine.

His work should explain the current appearance of the cosmos and the origin of life. "We will be able to see the beginning of the creation of the universe and how galaxies form first. We will find out so much about how the universe works," said Palab Ghosh, Science correspondent, who was present at the beginning of the telescope.
Alma, whose construction began in 2003, consists of a series of connected giant antenna deployed on the highest plateau in the Atacama desert, near the border of Chile and Bolivia.
In order to give the public a little insight into the work of the telescope, European Southern Observatory (ESO), one of the organizations which will operate the plant, has announced the first images recorded by the Alma and showing the collision of two galaxies. These colossal swarms of stars can be seen by optical telescopes, such as the legendary Hubble.
What distinguishes Alma, however, is that it can catch the light that is visible to the eye and make out thick clouds of cold gas from which new stars are formed.
The photographs were made using 12 antennas. The resolution and clarity of images will grow dramatically as they integrated new antennas that would by 2013. supposed to be 66th overall
Alma looks light in the millimeter and submilimeter frequency band which allows astronomers to identify the gas vortex is created at the beginning of the universe, more than 13 billion years ago and from which emerged the first stars that lit up the universe.
Astronomers will also be able to see the formation of planets around stars and to study supemassiv black hole in the center of our galaxy, which is due to dust can not see optical telescopes.
A Japanese research team plans to use for the study of Alma has a strange cosmic phenomena - particularly the light of the galaxy Himiko which annually produces about 100 sun.
In addition to being scientifically ambitious project of Alma and a miracle of technology and engineering. Pascal Martinez, the man who oversees the work of the plant, described Alma as a "pyramid of the 21st century." "The sheer size engineering project, its technical complexity and what they will achieve this hardware is innovative and built to the glory of mankind," said Martinez, whose task is to supervise the connecting antennas, each weighing about 100 tons.

Travel the universe from its inception

Bolshoi backward simulation using observations from the time of the Big Bang with everything we know about dark matter in an attempt to conjure up the beginning of the creation of the universe.

The universe is so large that we need the help of supercomputers to have only scratched the surface of what we assume that it happens.

It is with these supercomputers, scientists were able to create simulations Bolshoi - extremely detailed overview of the universe 14 billion years long.

Using recordings of microwave background radiation and outstanding after the Big Bang with a combination of everything we know about dark matter, the Bolshoi is offering scientists worldwide to study the material.

A sviam others only a fraction of what is going on above our atmosphere, in the greatest depths of the universe.

Manage with your fingers got a new dimension

Just as we got used to the phone and tablet computer controlled using a finger, the researchers of the University of Carnegie Mellon University will lead us to the next level.

They showed this week, a technology called TapSense to better use our fingers and allows better management of devices with touch screen.

They, in fact, no matter which part are the finger touched the screen, because they believe that touching the nail (nail) may signal one thing, a touch of cheek bone (fall), Article (knuckle) or with your fingertip (tip), something else entirely.

The technology developed involves the use of microphones nestle the screen, which allows them to accurately discern whether we have touched the tip of a finger, fingernail, or cheekbones čuknuli article. The system of proving the correctness of his concept for the time being is able to distinguish these four types of contact with an accuracy of 95%.

One of the goals of the team that developed Tapsens is to eliminate the need for buttons and other conventions that take up space to perform some action on the device and thus better use of sometimes limited screen size.

"Tapsens basically doubles the bandwidth of the touch screen," says Chris Harrison, a doctoral candidate at the Institute for the interaction of people and computers (Human-Computer Interaction Institute, HCII) at Carnegie Mellon. "This is especially important for small screens. If we remove buttons from the screen, we get more space for content or we can increase the other buttons. "

The same technology can be used to distinguish a number of different tools such as pencils, which can then be used to screen all the writes and draws a variety of colors.

Apocalypse will not be

Comet Jelenina, with which the apologists of the recent end of the world coming apocalypse tied, fell apart. Fateful role played by the comet near the Sun. This is stated Russian scientist Leonid Jelena who has found a comet.

16th October Jelenina comet was supposed to be closer to Earth at a minimum distance of - 0.23 astronomical units (34.9 million kilometers). This circumstance was born apocalyptic fever. Ostensibly the 2012th year because it will happen on our planet a global catastrophe. The Argentine astronomer Tuscany Sergio threatened arrival of the alien world, believing that the comet is actually spacecraft stranger, not a celestial body. Such ideas Leonid Jelena who discovered the comet, the 2010th called nonsense and I am glad he is that all this noise anti science finally ended.

It is clear now that this is not cosmic ship. Even many people who were entertained ufology ideas, they realized that the comet broke up and that scientists were wrong. She did not bring any disaster. Poles of the Earth have not changed, it fell to Earth. On it are not aliens flew.

Something similar, says Leonid Jelena, but it happened the 1997th when the world is expecting the arrival of cosmic ships that fly behind the comet Hale-bop. But the celestial body has successfully passed over the earth without any consequences for humanity. Although, according to scientists, when the comet was discovered that collided with Earth, a disaster would be inevitable. But the orbits of comets Jelenina was well known to astronomers, and everyone knew that she would pass on distance of nearly 35 million miles from our planet, which is 90 times the distance between the Earth and Moon. After passing point of the orbit closest to the Sun, the comet did not appear in the images of cosmic solar observatory SONO. A still earlier astronomy enthusiasts from Australia fix the sudden drop in its brightness. These events have led experts to speak about her death. Obviously a fateful role played by a guest of heaven is near the Sun, explained to Voice of Russia Leonid Jelena.
Each comet entering the country within the orbit, the comet before the "new dynamic" for the first time approaches the Sun, usually falls apart. It directly depends on its size, according to scientists, is determined by its composition. In particular it can be quite fragile body, a conglomerate of large icicles that when fluctuations in the sun and solar wind activity broken down into parts. I think it happened with the comet S/2010 H1.
Although comets are considered harbingers of historical cataclysms, Leonid says Jelena, we do not live in the 17th or 18 century, but in 21, therefore he must part with the medieval understanding of comets and realize that they do not carry any predictions.

"Nisan" introduced a new technology to prevent collisions

Japanese "Nisan" is presented, within the concept of "security shield", several advanced technologies that the company claims it can prevent an accident, even if the driver presses the gas pedal wrong before parking or when there is a chain collision on the highway.

"Nissan," says that the new sensor is able to detect the line at a parking area, a special safety device that allows control slow movement of vehicles or to automatically stop before hitting something in the parking lot, even if the driver confused the accelerator with brake.

Experts point out that company drivers are often misused pedals which is why a year in Japan about 7,000 incidents happen, and most crash occurs during parking. "Nissan," said the new system to help reduce that number.

Another Japanese car manufacturer has also developed a technology that is able to detect the sudden deceleration of two vehicles in front as they move through the streets, including highways and it warns the driver, which helps prevent chain collision.

"Nissan" is planned that the new warning system installed in vehicles for one or two years, said on Wednesday at the presentation of new security technologies in Tokyo.
