I have just returned to the game after a long time away and I notice quite a bit of change. When I scan ships I sometimes get 'blue' messages on the top right monitor saying things such as 'Aberrant Shield Patterns' or 'Decoded Emissions data' which is then stored in my log. Is this information of any value (in any way). Also after destroying ships, as well as cargo there is now material such as focus crystals. Is this material of any use, saleable or otherwise?
