... Future seminars . P a s t seminars . Seminar council . Is biochemistry alternative to earth one possible? ... Possibility of existence of life based on biochemical processes different from typical for Earth living organisms is discussing. ... They can be organisms used absolutely different material bases and solvents (i.e. methane life) and living under different physical and chemical conditions (temperature, medium composition)/ These organisms are rather often examining in literature. ...
... The problems of the investigation of the large dimensional complex system and the control of complex processes are well known. ... However, using statistical analysis it is impossible to determine a physical mechanism of the complex phenomena which is the key to find the control methods of complex system. ... It is known that control of such system is possible just at the detection of the stable enough regularities as the invariants by the lability and the variability. ...
Hubble Finds Oxygen Atmosphere On Jupiter's Moon Europa . Astronomers using NASA's Hubble Space Telescope (HST) have identified the presence of an extremely tenuous atmosphere of molecular oxygen around Jupiter's second moon, Europa . ... Europa's oxygen atmosphere is so tenuous that its surface pressure is barely one hundred billionth that of the Earth," said Principal Investigator Doyle Hall, of Johns Hopkins. ... The oxygen gas slowly leaks into space and must be replenished continuously. ...
