International Workshop on Astronomical X-Ray-Optics (AXRO) organized by the Institute of Astronomy of the CAS was focused on presentation and discussion of recent and future technologies for future X-ray astronomy missions. One session was aimed on astrophysical aspects of X-ray telescopes/satellites, in which some review talks were given from leading scientists in this field plus some presentations of relevant Czech scientists. The goal of the workshop was to present and to discuss recent and future technologies for X-ray astronomy missions. These missions require development of mostly inovative technologies, and discussed the possibilities, the results obtained so farm and new ideas in detail. It is obvious that the requirements of future large space X-ray optics based on Si wafers, advanced glass forming for precise X-ray optics, but also other possible technologies and alternatives, as well as related advanced metrology, measurements and tests. and Martin Blažek.
Vědecký poradní výbor evropských akademií (European Academies Science Advisory Council - EASAC) sdružuje akademie věd členských zemí EU, Norska a Švýcarska. Záměrem EASAC je připravovat evropským politikům nezávislá vědecká stanoviska a doporučení - každoročně vydává několik souhrnných zpráv nejen pro politiky, ale i laickou veřejnost., Oceans and seas play a crucial role in regulating our climate, nurturing biodiversity, and providing income and food to people around the world. At COP21, governments across the globe agreed that a more aggressive limit for global warming should be set as an essential step toward a more stable relationship between the ocean and climate. In spite of this positive direction, however, marine sustainability faces many challenges, according to a new report issued by the European Academies of Science Advisory Council (EASAC) and the European Commission's Joint Research Centre., and Ondřej Prášil.
