Biologists Cambridge University have developed a new method of creating stem cells - from components of human blood. This method of reproductive cells may be the most efficient of the existing, BBC Russian service reports with reference to the researchers.
At present, most stem cell scientists are of human skin. However, recent studies have found that these cells may have a genetic defect, and this makes them unsafe for transplant patients.
Stem cells can turn into any tissue of the body cells and can be used in the treatment of various diseases.Category: Science Read more [...]
American experts from the University of Colorado in a lengthy study concluded that coffee has a beneficial effect on patients with severe liver disease.
Scientific work lasted 4 years, it involved 782 patients suffering from non-alcoholic fatty hepatosis. The average age of the study participants, of which 38% were male, was 48 years. Of these, 29% do not drink coffee, 28% drank less than one cup per day, 15% of the daily drank two cups of coffee, and 28% - to drink a day for more than two cups of drink.
As a result, the researchers concluded that the admission of coffee has an inverse relationship Read more [...]
Experts from NASA dispelled rumors that the end of 2012 can be a cosmic catastrophe. Many publications have predicted end of the world December 21, 2012, but experts said the U.S. space agency, which is nothing like earthlings is not in danger, - "If the end of the world and there will be one day, it is unlikely we will know about it in advance".
Scientists explain that the rumors were caused misinterpretation of the Mayan calendar.

German scientists from the city of Bamberg conducted a study from 1993 to 2007, attended by more than 42 thousand women workers. As a result, the researchers concluded that the pregnancy can be "infected" by looking at someone else's example.Thus, according to the study, women colleagues who are already familiar withjoy of motherhood, the probability of getting pregnant within a year after the birth of the child with colleagues increases almost in half. Also, this effect is observed during the second year, although at a much smaller level.

The nature of the conscious mind "can be rhythmic." According to the National Science Foundation / U.S. NSF /, the conclusion made by experts at the Massachusetts Institute of Technology / MIT / Boston University and trying to solve the "one of the greatest puzzles in neuroscience" - to understand "how our brains encode thoughts on ... the cellular level. "Scientists led by Earl Miller of MIT conducted their experiments in monkeys trained to respond differently to certain things, depending on their color and location. It was found that the color "respond" Read more [...]
Experiments with collisions of particles carried by the most powerful particle accelerator today, the Large Hadron Collider (LHC), have allowed scientists to discover something that is very similar to a new, previously unknown form of matter. This new form of matter that has received a very strange name color glass condensate (color-glass condensate), is similar to the liquid wave, consisting of gluons, the elementary particles associated with strong interactions that hold the quarks together the protons and neutrons.Scientists working at the collider, it is not expected that the type of collision, Read more [...]
Scientists of the American space agency NASA convinced, despite numerous predictions that the end of the world in December of this year, will not occur."Our planet was fine for more than 4 billion years, and claims that the end of the world is coming soon, are without any scientific justification," - noted in a statement posted on its website.One of them, in particular, is that the Earth will face wandering in the solar system mythical planet Nibiru, which supposedly predicted the existence of the Sumerians. Originally disaster for this scenario was planned in May 2003. However, when Read more [...]
Swimming - is not only a sport that promotes not only physical development, but also mentally. This is especially true for children. Children who have learned the basics of the sport in a very early age, reach milestones of development, where before their peers. This is the conclusion of the Australian scientists Griffith Institute for Educational Research. Australian scientists have spent more than three years of his research in this area, the study of the impact of sailing on the brains of children. Scientists over the time of his research work with nearly 200 children younger, preschool Read more [...]
Collisions of protons with lead ions in the Large Hadron Collider (LHC) have led to an unexpected result in the form of new particles created in the collisions. The new observations show that the impact could produce a new type of matter called color glass condensate (through the eyes).
During the high-speed collision of particles formed hundreds noyvh particles, most of which departs from the place of collision at near light speed. But the team Compact Muon Solenoid (CMS) at the LHC found that out of a sample of 2 million ion-proton collisions, some pairs of particles in the departure maintained Read more [...]
Scientists from the Cooperative Association analysis of Internet data (CAIDA) at the University of California at San Diego (UCSD) with the help of complex computer models found that all networks, whether it is the brain, the social network, or the universe developed by the same principles.
A previous work has shown that the brain and the Internet have a lot in common. Now, researchers have wondered whether there are common laws of development of networks, independent of their size and type. Guided by the theory of relativity, which explains how matter distorts space-time, they decided to model Read more [...]
Guided horoscopes - means wasting your time and energy. The fact that they do not carry any useful information. Each person is unique, but all the words written in the horoscopes can go to absolutely any sign of the zodiac.Some people believe that the signs of the horoscope and the stars are controlled by external forces, writes Raut.ru. Thus, in their study, psychologist Bertram Forer instructed his disciples to assess whether the recommendations in horoscopes meet them personally. As a result, 85% of respondents reported that the horoscope is made very accurately and specifically suited to Read more [...]
Physics at times is so beautiful that it seems as if it is not of this world.
