Climatologists have determined that global warming is to get to the last bastion of the ice - such scientists called East Antarctic ice sheet, which was considered until recently affected by climate change. Research article appeared in the journal Nature Geoscience, and its brief cites New Scientist.

The new study researchers used data collected by a pair of spacecraft NASA GRACE. These devices were launched from the cosmodrome Plesetsk in 2002, devoted to studying the dynamics of the terrestrial gravitational field.

Downloaded, they said "most detailed available data on the change of the gravitational field in recent years, the computer model, scientists were that East Antarctic ice sheet is currently intensively melts. By their calculations, from 2002 to 2009 range annually lose 5 to 109 billion tons of ice (error calculations extremely large).

Physics managed to take another step on the road to create a new generation of electronic devices, called spintronykoy. It is planned that similar devices koduvatymetsya not only electrical signals, but the electron spin, their constituents. Research article appeared in the journal Nature, and its brief cites SCIENCENOW.

In the study scientists were able to create a flow of electrons from a polarized spin in silicon at room temperature. This plate for semiconductor causing a thin layer of aluminum oxide, after which the top was napylenyy nickel electrode.

Swiss human rights organizations and Trial Pro Juventute took up the study of video, which shows military action to find out how they symuliruyetsya real situation.

The list got Far Cry 2, Call of Duty 5, Battlefield Bad Company and others, only about 20 games. Human rights defenders came to the withdrawal of the actions that appear in games, violate the Geneva Convention and Additional Protocols governing the rules of warfare, the Kompyulenta from exile on the British Air Force language Corporation.

"Developers do not rotate aninaymenshoyi attention to any rules or sanctions was" - they argue. Particular attention is paid to researchers that comes from the civilian population, with buildings of cultural, religious and communal nature.

Scientists discovered in Hawaii rising flow of mantle that go in depth at least 1.5 thousand kilometers. Their existence explains the volcanic islands located in the center of plates of lithosphere. Job researchers published in Science magazine, and even put on the cover issue. Its main results presented in the portal Nature News.

Biologists have found that blue whales around the world were singing below, reports Wired. At this height the sounds issued from the 60-ies, is reduced almost linearly - the fate of a few Hertz in the year. Article scientists published in the journal Endangered Species Research.

Discovery was made by scientists, writing call sign whales in the Atlantic Ocean with automatic microphone - with time, researchers noted that the device requires an annual calibration. Data analysis allowed to establish that this pattern throughout the world.

Scientists have cited the following figures. In the North Atlantic (to which is the fullest array of data) the frequency of songs whales declined over the period 1960-2009 year with 22 hertz to little more than 18 hertz. The largest absolute decline is observed in the northeastern Pacific Ocean - from 65 to 45 hertz.

Okeanolohy stress in different regions of the songs of blue whales vary in height and structure, but the reduction observed everywhere. Currently, scientists explain it can not, however, they have a few hypotheses.

The average American consumes about 34 gigabytes of information per day. Top sources of information content is television, after the computer goes.

The data obtained in the new study scientists at the University of California San Diego, said Ruformator from exile to the newspaper The New York Times.

Total, the researchers calculated, all U.S. households consumed together in 2008, 3.6 zettabayt (zetabayt - a billion trillion bytes). This includes information obtained from various sources, including television, radio, Internet, text messaging, video games and more.

With regard to time, information on various vzhytok Americans, on average, does the 11.8 hours a day. The most popular information channel is television - on average, each American consumes him about 4.5 hours a day.

Next on the amount of time spent, is the computer - about 2 o'clock in the day. Other important channels are radio, music, and printing or publishing books.

Scientists have created a flexible antenna. This was reported in the press release at the University of North Carolina, whose staff participated in the work. Article scientists appeared in the journal Advanced Functional Materials.

On the basis of the new device, gallium alloy and India, which remains liquid at room temperature. Researchers have flooded the present alloy in a porous material (eg plastic strip with thin channels), then at the border section of media occurs oxide thin film of this alloy.
