Certainly there is no substitute for experience i.e. reading papers all your life will inevitably help. It's hard to find current affairs snippets as news items tend to expand on subjects that develop over time as opposed to restating old history.
You might try talking to people - parents, teachers, friends, ATC officers - whoever you've got access to. Sometimes even a small amount of background knowledge can explain a lot about current problems.
Also, people at OASC will most likely be discussing such topics frantically in the bar before the interview, though I wouldn't rely on that as my sole source of info....
All in all, good luck. Serious digging is likely to turn up enough in eight days if you have that time to spare.
Best of luck
PS. Agree on the 2DTV thing
