In LPI produced the first single crystals of the new high-temperature superconductors based on iron

In the Physics Institute. Lebedev (FIAN) synthesized a new crystal high temperature superconductor (HTS) based on iron. At the end of last year was completed laboratory equipment for solid phase synthesis and the growth of crystals of high-temperature superconductors. The result of the first experiment showed the fundamental possibility of such crystals in the LPI.

Recently was exactly one hundred years since the discovery of superconductivity by Kamerlingh Onnes. In the initial period of its superconductivity carriers were mainly metals, and the maximum temperature does not exceed the critical 10K (9K in Nb, 7.2K in Pb).

Sensitivity Greenland warming has been exaggerated

The Greenland ice did not melt completely and weaker-than-expected reaction to the temperature rise during the last interglacial warm climatic period of about 120,000 years ago, and primarily responsible for the rise in sea level at that time to bear the Antarctic ice, NEEM project participants write in the article, published in the journal Nature.

In this project, scientists from Denmark, Russia, USA, Sweden, Canada and several other countries are drilling Glacier in northwestern Greenland. The study of the isotopic and chemical composition of the ice and its other characteristics allows scientists to judge the temperature and composition of

Frosts reached and Africa

Unprecedented cold came in Tunisia. Fallen snow, reaching 20 cm and above, has led to the break lines and blocking roads.

In the central and eastern parts of the country the temperature dropped to minus 4 degrees. Many schools have been forced to stop work.

Rare climatic phenomenon associated with coldness and snow, were also found in the south. There's such sediments have not seen since the 1970s, according to ITAR-TASS.

The northern and central provinces Algeria also at the mercy of raging winter elements. Due to snow and rain cut off from the outside world were a few

U.S. melts of record heat

 

Texas, Oklahoma and Arkansas faced a wave of record heat — the thermometer showed 40 degrees in the shade, hospitals are overcrowded and bring relief only destructive storms.

In the U.S., real weather drama unfolds after a series of deadly tornadoes in the country came to a stifling heat.

The temperature in the shade is above 40 degrees, the hottest weather in states with a dry climate: in Texas, Oklahoma, Kansas and Arkansas.

Absence of clouds in the sky cause intense heating of land, which in turn leads to an even greater increase in temperature. Forecasters do

Unprecedented heat prevails in Argentina with the onset of summer

Unprecedented heat prevails in the environment in the central and northern Argentina, with the onset of summer in the Southern Hemisphere, said the Argentine National Meteorological Service (SMN).

In most provinces the temperature rose above the level of 40 degrees, exceeding the usual 10 degrees for the month options.

The country has dramatically increased power consumption due to the increased use of air conditioners, fans and refrigerators.

On Wednesday at 3 o'clock in the afternoon (22.00 MSK) in the city of Santiago del Estero, Tucumán, Chaco, Formosa, Catamarca expected temperature of 44 degrees Celsius. In Buenos Aires, will be

Meteorologists expect the arrival of the center of Russia snowy and windy weather

Frost and sun at the center of European Russia to the environment will change cloudy and windy with snow, thaw, which will be replaced by the end of the week a new cold snap, according to the Russian Hydrometeorological Center.

According to meteorologists, on Monday and Tuesday, the weather in the central region will determine the anticyclone, on Tuesday night frost will increase to 4-11 degrees below zero, sometimes up to 12-17 degrees, but the day will thaw.

From Wednesday the weather will form a series of active North Atlantic cyclones. "Weather will be highly volatile. Amid falling atmospheric pressure

Shocking weather scientists in 50 years half of Ukraine will become a desert

After 100 years in Ukraine warmed by almost one degree, it already felt shellfish and praying mantises, and harmful ambrosia of Donetsk reached the most Carpathians. The latest report of the United Nations, dedicated to the fight against global climate change, scientists have predicted that because of the disastrously rapid melting of glaciers in the world ocean levels by 2050 could rise by an average of 90 centimeters, so that the water will leave the whole island states (eg, Kiribati in the Pacific), as well as parts of larger islands, such as, for example, the United Kingdom (the report

Winter weather in Russia is changing for pre-spring

In the first days of spring weather calendar Central Russia retain anticyclonic character. However, there will be a number of positive developments, including the erosion of clouds and weakening wind. This will add a pre-spring weather is comfortable, although the temperature will remain well below the norm — at 6-8 °. At night, the air will be vyholazhivatsya to -14 … -19 °, and the day will warm to -5 … -10 °. In the second half of the week, the situation will change in the atmosphere. In the northwest is expected series of North Atlantic cyclones, which bring warmed

The water in the lagoon of Venice became dangerously hot

Researchers at the University of Southampton, and colleagues from Venice found that surface water temperatures in the Venice lagoon is growing 10 times faster than the average in the world. Such changes are particularly critical for the city in winter. Some experts believe that climatic surprises and unexpected sharp rise to unsafe water indicators can affect the tourist attraction of the city as a whole. But Venice is visited by 22 million people a year, which significantly adds to the state and the city treasury.

Besides tourism and fisheries will suffer, as the warming of water it contains less

Record cold weather in the U.S., and will be even colder

A wave of cold weather, which came to the U.S. Great Plains, brought record low temperatures in several states. In Oklahoma the first recorded minus 35 degrees, and will be even colder.

Unusual location of cyclones in Greenland and northern Canada sends cold Arctic air in the U.S. and even in northern Mexico.

Each day the temperature is lower and lower. And because the sky is clear, the heat is actively evaporated from the soil. The further north the United States, the closer to the historical temperature records.

Yesterday in Novatus in Oklahoma thermometers showed minus 35 degrees, and
