Can you feel that someone is watching you (even when you're asleep)?

We are "connected" strangely and yes, if we can know when we are watching, even when we do not see.

The research, conducted by scientist Colin Clifford, University Vision Centre of Sydney, found that the human brain is geared to assume when others are watching even when there is little or no evidence of it.

The researchers say that this feeling is designed to put us on alert. It turns out that we are "wired" to feel when others are watching.

A direct look can be a sign of a dominant position or a threat, and we would not be attacked. Normally we check the direction of the head and the position of the eyes of people to see if they are watching.

However, the study found that when people can not see the eyes of others, he is found in dark conditions, or the other person is wearing sunglasses, the brain just knows.

In the study, researchers asked people where several faces were looking for.

Judging others look if we can come naturally, but it's really not as simple as our brains have to do much work behind the scenes

Even when people could not tell, they tended to think they were being watched.

So the perception does not only involve visual cues, our brains generate alleged experiences and match what we saw at a given time.

Aside from worrying about the impending danger, our brain is prepared for interaction and conversation can color our judgment. Since the direct gaze is often a social signal that the other person wants to communicate with us.

The challenge now is to determine if the trend is genetic or learned.

People with autism are less able to tell if someone is watching. By contrast, people with social anxiety are more likely to think they are under the gaze of others.

AIDS vaccine is about to be put first in humans

We hope you're about to see how it changes the history of this terrible deadly virus, the vaccine has been developed in the last 15 years by Robert Gallo, the scientist who demostróen 1984 HIV triggered the disease. Phase I of the implicará60 test volunteers and simplementepondrá proof security andthe immune response to the vaccine, so we will not know for sure for a while if it will be really effective comparison of otras100 + AIDS vaccines have been tested in the last 30 years. So far there have been extensive testing in monkeys to positive conresultados. They had done some candidatasprometedoras vaccines in the past, but the challenge of AIDS is that HIV directly infects white blood cells called T cells, which literally causes our immune system is against us. And once the virus has entered a T cell, it is invisible to the immune system. The only chance we have to prevent infection would be triggering antibodies against proteins of HIV, before we attack, how difficult is the fact that the retrovirus can periodically change to hide their viral envelope proteins on the surface of the cell. Gallo and his team of scientists from the Institute of Human Virology in the US, say Fumes may be found when the protein on the surface of HIV, known as gp120, is vulnerable to detection (the time the virus binds to T cells in our body). When HIV infects a patient, the first link reaches the CD4 receptor found on white blood cells. The transition then exposes hidden parts of the viral envelope, allowing them to join a second receptor called CCR5. Once HIV binds to these two receptors of T cells, successfully infects immune cell. And at that point, it's too late to stop. The vaccine known as "single chain length" contains the gp120 protein of HIV surface, designed to link a few portions of the CD4 receptor. The aim is to trigger gp120 antibodies when it is already bound to CD4 and is in its vulnerable state of transition. Profectus BioSciences, a biotechnology and the Institute of Human Virology Gallo, explaining who have taken the time to get to this point because they have been very careful in testing in monkeys, as well as financing the development of the drug human vaccine quality.

Wing space junk impact Earth in November

Scientists report that a piece of space junk impact the Earth at 6:20 UTC on November 13, and will fall into the Indian Ocean about 65 kilometers off the southern tip of Sri Lanka. Nicknamed WT1190F, the curious object was rediscovered this month after scientists had forgotten him, as a result of lost track of its orbit beyond the moon. It is believed that measures between 1 and 2 meters long, and is on a collision course with Earth, presenting a unique opportunity for researchers to observe the entire impact event from start to finish. Detected a few weeks ago by the Catalina Sky Survey, the University of Arizona in the US, WT1190F travels at a highly elliptical orbit, swinging twice farther than the distance from Earth to the Moon, her movements indicate that hollow inside, according to Traci Watson. This means it could be an old piece of space rock. But researchers say it could be a missing piece of space history has come back to us. As a piece of rocket Apollo mission. No impact is expected to meet much of the world's attention, but the scientists involved are certainly grateful for the opportunity to test global networks that are in place to monitor much larger and more threatening cosmic visitors. WT1190F might be the only impact it will have in the near future (we know), but not the only close encounter we can expect in the coming weeks. On October 31, 2015 TB145 asteroid will pass too close to Earth, an event that had not occurred since July 2006. It is easy to forget that our planet is only a small part of a huge solar system incredibly full of asteroids, comets and trash heap. Remember that we are not alone here.
