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.

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.

In Runet, according to recent data, there are about 40 million visitors over 18 years. When measured by the Russian segment of the audience, "forget" about children and adolescents. This is a huge number of orphaned users - one for data in Runet 4 million, and on the other - 8-10 million children.

All of them scored network along with adults. The study, conducted in May 2009, show that three-quarters of young runetchykov are in the network itself. About half of them do not meet the resource for content, but the other half of the talent less.
