How researchers look at the bird brain in action
How do birds make decisions and which brain regions are particularly active when they solve tasks? Researchers from Bochum are investigating these questions. So far, only anesthetized birds and therefore passive experiments could be examined using the functional magnetic resonance imaging (fMRI). Thus, the examination of brain processes during active tasks was not possible. Now the researchers have constructed an experimental set-up which allows them to carry out fMRI examinations on awake pigeons and thus also investigate cognitive processes for the first time.

Iron is to blame for carbon dioxide emissions from soil, says a soil scientists from RUDN
Iron minerals and bacteria can be the main agents of carbon dioxide emissions from the soil. A soil scientist from RUDN University made this conclusion after studying the process of organic plant waste decomposition of the micro-level. Iron and hydrogen peroxide enter into a reaction, as a result of which active oxygen forms (oxygen radicals) are formed. The radicals destroy plant waste in the soil and promote carbon dioxide emissions. (2020-09-09)
