Space flights cause a failure in the immune system of a person
The results of two studies of NASA, recently published in the journal journal of Interferon & Cytokine Research suggest that spaceflight may cause temporary changes in the immune system of crew members who are long time on Board the International Space Station.
Data obtained at an early stage of one of the experiments showed that the distribution of immune cells in the blood of crew members during the flight remained relatively unchanged. However, they found that some cell functions were significantly reduced, while the activity of another cell type, on the contrary, increased. That is, in a sense, the immune system of crew members, it failed.
If the cell activity is suppressed, the immune system cannot adequately react to threats, which can lead to asymptomatic for the virus. If activity is increased, the immune system becomes too sensitive, which can lead to the development of allergic reactions and persistent rashes, as well as reported some of the crew members.
In another study, scientists analyzed blood plasma, measuring the concentration of cytokines – proteins that regulate the immune system. Continue reading
People were engaged in agriculture in the stone age, 30 – 35 thousand years ago. This is evidenced by the notches on animal bones and rocks, cave paintings. This is, perhaps, the earliest “scientific notes”, in which the authors noted the different phases of the moon and count days and nights.
Monitored by our astronomical instruments, the universe consists by weight of about 76 percent hydrogen and 23 helium. Only slightly more than one percent accounts for all other elements of the periodic table.
It is estimated that the galaxy contains more than a hundred and twenty billion stars and to represent its enormous size, we will give one comparison: if the path from the Sun to Earth light travels in 8 minutes, the diameter of the galaxy it will for a hundred thousand years.
To show the progress made over half a century in the study of the Universe, astronomer Paul Couderc came to a startling comparison. Suppose that all known astronomy to 1900 area of the Universe displayed on the plan area of one square meter. Continue reading
The state Museum of the history of cosmonautics named after K. E. Tsiolkovsky (GMIC) was opened in Kaluga on 3 October 1967, Thus he became the world’s first Museum devoted to its exposition about the history of space exploration. For over thirty years in the Museum of systematic work on the collection, preservation, scientific study, historical heritage in the field of history and practice of space research in our country and abroad.
The actual history of the Museum began in 1936 when the first anniversary after the death of the great Russian scientist, Konstantin Tsiolkovsky. the founder of theoretical cosmonautics, the Creator of the cosmic philosophy, in his home in Kaluga was opened the memorial Museum in his name. This Museum, which is a real pearl of Russian culture from 1967, became a division of the Museum of the history of cosmonautics. The grave of the great Russian scientist with a monument above it is far from main building GMIC.
The initiative to create the Museum of cosmonautics in Kaluga was owned by the outstanding scientists of our time: Sergei Korolev, A. N. Tupolev, A. A. Blagonravov, I. P. Bardina, L. I. Sedov and others. Continue reading
