    There are no radio-emission sources in the Antarctic, and this allows scientists to find traces of neutrinos penetrating the thick ice layers. For this purpose, physicists use powerful radio antennas that resemble ordinary radio telescopes in terms of their operation.

    To unlock cosmic mysteries, physicists have turned Antarctic ice into a huge detector. They use it to locate neutrinos with extra-high energy (traces of the most powerful explosions and cataclysms in the universe).

    Each year, scientists launch balloons with high-tech equipment from the McMurdo Station for this purpose. Physicists from the National Research Nuclear University MEPhI are conducting the Antarctic Impulsive Transient Antenna (ANITA) experiment to search for ultra-high-energy (UHE) cosmic neutrinos together with the NASA Astrobiology Institute at the University of Hawaii.

      Power Blooming: What Flowers Global Leaders Prefer

      Although they say that life is no bed of roses, it sometimes seems quite the case for world leaders. While the German media seeks for the "hidden meaning" behind Vladimir Putin giving Angela Merkel a bouquet during their latest meeting, Sputnik presents many of the flowers their counterparts have given each other over the years.

      Nostalgia: Soviet Pioneers' Day Back in USSR

      May 19 marks the 96th anniversary since the founding of the Pioneer movement in the USSR. The day that a person would join the movement was a very important event in every Soviet adolescent's life.
