Study shows how permafrost releases methane in the warming Arctic


 E-Mail
Researchers from Skoltech have designed and conducted experiments measuring gas permeability under various conditions for ice-containing sediments mimicking permafrost. Their results can be useful both in modeling and testing techniques for gas production from Arctic reservoirs and in tracing methane emission in high latitudes. The paper was published in the journal
Energy&Fuels.
Permafrost, even though it sounds very stable and permanent, is actually quite diverse: depending on the composition of the frozen ground, pressure, temperature and so on, it can have varying properties, which are extremely important if you want to build something on permafrost, such as an oil and gas field. Permafrost is also very gassy: it may contain a lot of natural gas in the form of hydrates, and its permeability is an important parameter both for research and for many activities in the Arctic. ....

Researchers from the Moscow State University of Psychology & Education (MSUPE) are developing a unique gaze-based system to control a computer with the power of thought .
According to its creators, the system based on reading the brain s magnetic fields may facilitate the use of computers by disabled persons. The study s results were published in the journal Frontiers in Neuroscience.
Gaze-based computer control is increasingly being used by paralysed people, and the eye control function is even included as a standard feature in some operating systems, MSUPE researchers said. An eye-gaze tracking device, an eye tracker, is used for this purpose. The eye tracker detects the position of the user s pupil with a video camera and calculates ....
