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).

Mars rover right rear wheel "spirit" (Spirit), stuck in the sand in April 2009, ceased to rotate after attempts to deliver aid engineers. Details of rescue operations Path brought us to Space.com.

Engineers are developing tactics rescue "Spirits" for several months. Initially they worked at the Earth from Mars rover model in size, placed in a container with sand. November 20 scientists began to send commands "Present" "Spirits." Diagnostic tests conducted after the Mars rover executed the instructions of experts, showed that one of the wheels stuck in the sand. However, a later test did not show any disruption to the wheels.

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.

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.

The experiment at the Large Hadron Collider on Monday was halted due to problems in the cooling of superconducting magnets. Evidence that suggest the absence of the beam, appeared at CERN, which displays information about the status of the accelerator (it is given to illustrate the screenshots to this news).

Scientists have offered to defend the Earth against dangerous asteroids, providing them with special "tails" of the counterweight. The resulting structure thus resembles weapons Brazilian Indians bolas.

According to the catalog NASA, is currently known about 1000 asteroids that could potentially threaten Earth. Until recently, most dangerous of these objects was considered an asteroid, 99942 Apophis, which, after detecting a collision with Earth is predicted with certainty about 0,027. Later however it became clear that the probability of very overrated.
