Psychologists found out that the position in which married couples sleep can tell a lot about their relationship and personality traits. The new study has also provided important information about the preferences of extroverts and creative people. Professor Richard Wiseman of the University of Hertfordshire conducted a large-scale study, during which he managed to interview more than 1,000 people.
The scientist was primarily interested in the question of how the position in which couples prefer to spend the night can reveal things about

Oddly enough neither the reasons nor the evolutionary origins of sleep are known to science. From the standpoint of nature, sleep is hardly something worthwhile. If a person or animal is sleeping, his mind is ‘turned off’ for several hours. Needless to say, that in this state the chance of being eaten by predators grows significantly.
And yet, some regularities, if not reasons, of sleep were discovered by scientists. It turned out, for example, that adults who sleep 6 to 8 hours are characterized by Continue reading
Immunotherapy against cancer, namely the recruitment of the immune system to eliminate tumor, was considered by the «Science» magazine the main achievement of 2013, which became a “key year” in the war against cancer. The leading magazine presents a list of nine other major developments, from understanding the function of sleep to the transparent brain.
Breakthrough of the Year
“Immunotherapy against cancer won first place because it changes the mindset of researchers on how to treat the cancer,” writes the magazine. Continue reading
It is believed that one day the development of technology will be the cause of death of humanity. And judging by the research projects of the last decade, it may happen sooner than we think, since the modern scientists in their quest to streamline and improve everything sometimes go too far. Here are several controversial scientific developments, which in the future can be dangerous for mankind.
1. Reanimated deadly virus
In 1918, the “Spanish flu” cost an estimated 50 million lives before the human immunity learned to cope with this terrible disease. In October of 2005, the staff of the U.S. Centers for Disease Control and Prevention removed the virus genome from the lung tissue of victims buried in the permafrost in Alaska and took it to one of the laboratories.
The researchers believe that the study of the Spanish flu will help them understand what may be dangerous for human avian influenza virus H5N1 and the way it can be transmitted to humans. According to Erling Myhre, a specialist in infectious diseases, the reanimation of the “Spanish flu” is perfectly safe – just one year after removal of the virus the researchers presented a vaccine against it.
However, not all scientists share the optimism of Myhre; for example, Jens Kuhn, a virologist at Harvard University, believes that there may be a Continue reading
The social networking sites such as Twitter and Facebook may have revolutionized the way we communicate, but have also messed up our real life, new study claims.
As revealed by the study of the Technology Policy Institute in Washington, with every hour spent in Internet surfing, a user “loses” about 16 minutes from work.
The navigation in the “ocean” of websites seemed to also affect sleep and social life of users, since with each hour in the online world the user lacks seven precious minutes of sleep and 17 minutes of going out in the outside world, which corresponds to approximately 18 whole days away from friends and families a year.

1. Do not sleep on an old bed
Replacing an old creaky bed with a new one, you add yourself 42 minutes of quality sleep – that was the average result in an experiment conducted by the British organization The Sleep Council. And do not forget that the mattress should be replaced every seven years.
2. Perfect temperature
4 hours after you fall asleep, the body temperature reaches the minimum level (which is possible without any consequences for the organism). This provides you a deep sleep. But if the room is hot, it won’t happen. The best temperature is between 18°C and 24°C.
3. Your window
There is no need to put light-proof curtains in your bedroom. The best choice is ordinary curtains, screens, blinds, which let light through in the morning. The natural change of light and darkness is Continue reading
When we sleep, external stimuli become part of our dreams. Our brain has the ability to integrate the ‘interference’ in dreams in order to make us remain in the sleep state.
Therefore, there are several factors that influence the events and sensations in our dreams. What are they?
Have you ever dreamed that your alarm clock is ringing? Such dream can be caused by the sound coming from an alarm, and it shows how the sounds you hear may actually be Continue reading
Everyone has fears, either kept private or expressed openly. Some people get trembles and shaky hands at a fear of public speaking, or supervisors, some people are afraid of heights, high speeds or stuffy confined spaces. Phobias are a common thing, but letting them go is not so simple. Soon it may become possible to replace sessions conducted by psychiatrists with an unusual and pleasant treatment … during our sleep, scientists say.
Are you afraid to ride subway, to meet with your own boss or look down from the balcony on the fifth floor? Perhaps, getting rid of these phobias, instead of a chair in the office of a psychiatrist, pillows and blankets will be just as efficient. Targeting brain activity during sleep can help mitigate the effects of fear-inducing memories, researchers claim. Continue reading
Most likely you’ve experienced a sudden strange sensation of falling when going to sleep, which rudely awakens you. In reality it is not a dream of falling, which happens in deep sleep, but an instant physical sensation that wakes us and is accompanied by a hallucination, not a dream.
To better understand this phenomenon, it is necessary to understand the mechanism of sleep.
Dream begins in a part of the brain called reticular formation, which sends signals to the spinal cord to relax the muscles and suppress stimuli. The jerk that you feel when you wake up does not wake you when you have already fallen asleep, because the body absorbs its own consciousness. Everyone agrees with this. But then the scientists’ opinions differ. Here are 3 possible explanations of this phenomenon: Continue reading
1. How did life originate?
For 80 years now we are told that the first self-replicating molecules appeared in the primordial soup in the Earth’s shallow waters, which happened 4 billion years ago. This “soup” was composed of amino-acids, polypeptides, and nitrogenous bases of nucleotides formed as a result of electrical charges, high heat and cosmic radiation.
However, the experiments to replicate similar processes have given mixed results: the basic monomers began to form substances that prevented the expected complexity to exist in this “soup” of polymers.
Later, the problem seemed to have been simplified by the “RNA world” hypothesis, but the probability of spontaneous formation of RNA, which would Continue reading
