The researchers use a fish called the bluegill sunfish to detect industrial and agricultural discharges in tap water. Environmental changes cause changes in the behavior and character of breathing fish. Electrodes are placed in the container in which the fish swims in the water from a nearby water supply system, and if conditions change within the container, a beep alarm.Do you know where it comes from your water? Tap water comes from different sources. Before it reaches the tap, water purification plants purify water from lakes, rivers and reservoirs, but still there is a risk of contamination Read more [...]

Russian scientists from the Institute of Cytology and genetics, Siberian branch of the Russian Academy of Sciences (Institute of Cytology and genetics SB RAS) learned how to grow water hyacinth, which successfully absorb radionuclides and languid metals, cleaning the dirty area. This will help scientists to "revive" the victim radiation from the explosion of the city of Ozersk, Chelyabinsk region. We threw hyacinth radioactive ponds, and it is amazingly absorbs the available water volume metals, radionuclides strontium and cesium. In laboratory criteria non-radioactive isotope of strontium may Read more [...]
At the end of the XVIII early XIX century in the field of theoretical development issues metallurgical advanced French scientists laid the foundation for a new scientific approach to technology. Deciding to take advantage of their knowledge and experience, NN Demidov, owner of nine large, well-equipped Nizhny Tagil plants, decided to invite the Urals former Jacobin, scientist-metallurgist. Dr J. Ferry. Although zavodovladelets Demidov was a stranger any "freethinking" and was a staunch serf he made this decision because I was prudent businessman. He made much Read more [...]

An instance is the oldest of all found
Scientists note that the calendar developed by ancient scholars, quite accurately describes the lunar and solar cycles, as well as the movement of the brightest stars. Most likely, it was used for rituals.
New archaeological finds debunks the theory predicting ancient Indian Mayan people doomsday December 21, 2012.

To make the tutu stained porridge, almost the third part from the raw material delivered to the Elevator, just throw. Grain separated from the husk. This part of the production chain. But what to do with this husk later? Moreover, in such volumes. Salivate and bury all this is expensive and not environmentally friendly, although so at the moment do. But researchers from the Altai science city Biysk believe that remade specifically such waste, which are not necessary, will earn a billion From the husk of the oat scientists have learned how to allocate cellulose. It, in turn, in laboratory criteria Read more [...]
Scientist derived a formula zombie apocalypse
Canadian mathematician sure if the undead invasion begins, people have no chance to survive.
Canadian mathematician Robert Smith is confident that with the virus infecting everyone on the planet will turn into the walking dead very quickly, writes Daily Mail. Scientists deduced the formula can be used to simulate the spread of disease in the modern world, says NBC News. Smith published his research in his book "Mathematical modeling of zombies."
Here is the equation of a zombie apocalypse: (bhN) x (S / N) = XZ bhShZ. N - total population, S - the Read more [...]

Another theory about the coming end of the world, which, according to the Mayan calendar has come December 21, 2012, launched the famous physicist in charge of energy Earth Anka Dinke.
Romanian scientist said that December 21, 2012 frequency of vibration of the Earth reaches its climax - 12,6-12,8 Hz. According to him, some people at the same time can experience discomfort, but the end of the world will not, said the scientist.
He advised mankind to relax, go out with my family and celebrate "the most beautiful apocalypse."

Remarkably high intellect of Albert Einstein associated with unusual features in his brain. A new study suggests that the genius of Albert Einstein may have been associated with the unique shape of the brain.With the permission of the family of Albert Einstein, his brain was removed and photographed after his death in 1955. It is also divided into 240 blocks for histology. The researchers compared the brains of Einstein with normal human brain with a level of intelligence to 85, to determine whether or not it has a unique feature.As a result, it was reported that although the overall size and Read more [...]
Astronomers have expressed suspicions that the star, which they believed, exploded this year, in fact, staged his own death in order to connect to it by a mysterious companion. So sometimes the universe begins to resemble a bad melodrama.
If in fact this is the case, the wonderful stars in the sky has more. It's about the product of the merger of stars that can change our ideas about what is the chemical composition of our universe.
Luminaries are powered by nuclear fusion, which means the conversion of hydrogen into helium in the cores of stars. When sufficiently massive star ends hydrogen Read more [...]
7 November. To reduce the global temperature by 1-2 degrees and mitigating the impacts of global warming enough to spray in the atmosphere from 1 to 5 million tons of aerosol particles, said academician Yury Izrael, Director of the Institute of global climate and ecology of Roshydromet and Russian Academy of Sciences.
Previously, the scientist stated that the measures of the Kyoto Protocol, aimed at combating emissions of greenhouse gases, are ineffective and will not be able to keep the global temperature rise within the boundaries of 2 degrees by 2050. To cope with the ongoing warming can help Read more [...]
In 1785, Pignataro - the same Italian scholar which believed that he had found the dependence of the position of the moon quakes in the sky - created the scale. After nearly half a century, a similar proposal was made by a German scientist Egen. Like that, and another scientist were right ideas, but none of them had no such information, which would create a satisfactory scale. Therefore, the scale proposed by Pignataro and Egenom are not commonly used. But in 1878, two other researchers have jointly developed a fairly easy comparative scale. These were representative of Italy De Rossi and Read more [...]

Development Pathology as a research method in the 19th century led to a conflict between two of its trends - humoral (from Lat. humor - liquid) and cellular. Representative of the first - Viennese pathologist K. Rokitansky cause painful phenomena considered changes in the juices of the human body. German pathologist Virchow in his book "cellular pathology" (1858) argued that the source of the disease is not a normal cell activity ("the whole pathology is pathological cells"). Virchow was the application of the merit of the doctrine of the cell to the study Read more [...]

In the 19th century when industrial capitalism advances of natural science, especially physics, chemistry, biology, and then allowed to enrich medicine in new ways. Three major discoveries have defined a new era in science and influenced decisively and medicine: "The knowledge of the interconnection of processes occurring in nature, moved giant steps forward ... First, thanks to the discovery of the cell ... Second, thanks to the discovery of the law of conservation and transformation of energy ... Third and finally, for the first time presented by Darwin coherent proof Read more [...]
January 12. In Siberia, undertook a study of the influence of huge VASIUGAN marshes area of 53 sq km, to climate warming in the region. The initiative to test this hypothesis was made by the Center for Space Monitoring of Altai State University / ASU /, Graduate Faculty of Physical Engineering ASU Maxim Yakunin.
In his view, VASIUGAN, considered one of the largest wetlands in the world, significantly affect the climate in Siberia, making warmer here and the winter and summer.
Confirm or disprove the hypothesis help Yakunin colleagues from the Center of Space Monitoring ASU. They process derived Read more [...]
