Corpses can be a wonderful source of donor organs and stem cells, says New Scientist. Large number of cells can be collected from the brain stem, even five days after the death.In the bone marrow contains mesenchymal stem cells that can turn into bone cells, cartilage, fat, which makes them ideal candidates for transplants. Unlike other materials transplanted, these cells do not cause rejection reaction. They, on the contrary, calm the immune cells. The persistence of mesenchymal stem cells from the fact that they live in an environment with low oxygen content, according to a study at the University Read more [...]
Recently opened in astronomy so much new that choosing excellence is very difficult. So, the most-most discoveries about ... Black Holes ... Here and think of nothing: a supermassive black hole that lives in a lenticular galaxy NGC 1277 constellation Perseus, the strangest and also the largest of the known black holes (BH). It weighs 14-20 billion mass of our Sun, or 4000 mass of Sagittarius A *, the most massive black holes in our galaxy, or four times the "weight" of the heaviest of reliably known until the black hole of the universe. All of this is particularly unusual on the Read more [...]
Reasonable prehistoric worms, math parrots, crows with cause and effect, the monkeys with poluchelovecheskogo tool - especially all the distinguished intelligence in the past year.The outgoing year was marked by a number of notable discoveries in the field, which can be called research mind.

In Italy they put seismologists who failed to predict the earthquake. Say thank you, that everyman has not filed suit against pesky climate scientists who write about global warming.The history of relations between the layman and the science is interesting and monotonous about the same extent as the history of relations between Romeo and Juliet: all the way to the same thing, but every time a new way. In the departed, almost new stories to be written, but the old stories were exciting continuation of what we have here and the sweet little pobrenchim Christmas brew.

Specialists from Europe discovered a previously unknown type of nerve cells in the brain that regulate cardiovascular functions such as heart rate and blood pressure. It was originally discovered in mice. As the researchers found, these neurons in the brain are formed with the participation of thyroid hormone. According to them, in patients with impaired thyroid function is a high risk of problems with these cells, which in turn can lead to heart disease - wrote Rossiyskaya Gazeta. Recall that the brain cells include neurons that generate and transmit nerve impulses and glial cells, with important Read more [...]
The region has opened Russian research center of this mysterious natural phenomenon, from which each year die Court, oil platforms and millions of people. Earlier killer waves felt horror stories, but now they were engaged scientists to understand how to fight. Report correspondent of Channel Alexey Zbarsky. Killer waves - this is not a horror story, invented by scientists to terrorize the inhabitants, as well the official term. It reflects the essence of the phenomenon - in the ocean suddenly, without there seeming wall of water height of 30 meters or more, which is moving at great speed. Read more [...]
Researchers from Kiev implemented innovative world-class research. They managed to take a fresh look at the factual material accumulated scientific world Phthisiologists for the period of its development. Conventional methods of assessment before that time did not allow to solve internal conflicts. On the internal contradictions of trying to hush up. Any material regarding these issues ignored. How not to recall here the words of Professor Valerie Mizrahi, director of the Department of Molecular Mycobacteriology National Health Laboratory in Cape Town that scientific publications must be honest Read more [...]
Who would have thought that classical electrodynamics throughout the two hundred years of the development was on the wrong path. They were wrong, everything from Ampere, Faraday, Maxwell, and Hertz and ending Einstein. That the induced electric field, including the radiation field are not of the vortex, and the nature of the gradient, and that the magnetic field is just a mathematical fiction, and the charge is not an invariant speed. Landau in a nightmare could not have dreamed that the frequency dispersion of the material parameters such as dielectric constant and magnetic permeability, it Read more [...]
Psychologists say that the information about the coming catastrophe that threatens the destruction of the world is useful to man, pushing for a revision of attitudes.From the words of psychologists, people who believe in the apocalypse, want change for the better, reports MyJane.

Person blinks more often than is required to wet the eye, because this action helps the brain "reset" its current state and to switch attention.
This say scientists in a paper published in the journal Proceedings of the National Academy of Sciences.
The average person makes about 15-20 blinks per minute, which is completely redundant in terms of wetting the cornea. According to the calculations of biologists, people spend on blinking to 10% of waking hours. Excessive concern about the state of the body eyes long remained a mystery to scientists.
Group of neuroscientists led by Tamami Read more [...]
Mesenchymal stem cells that live in the bone marrow and live for at least five days after the person's death. Lessons from there, they can turn into specialized cells of the cartilage, bone and fat.Feature of mesenchymal stem cells in that they do not irritate the transplant someone else's immune system - in contrast to other transplantable tissues. In addition, these cells live in the bone marrow, can be converted into a variety of tissue types: the cartilage, bone, fat, etc. The injection of mesenchymal stem cells can theoretically restore damaged tissue in the heart after a heart attack.
