I'm not sure about any current news story ideas, but I've written 3 episodes just for fun (and to practice screen writing). The first is titled "The Lady in the Labyrinth" that I mentioned on this site before. The bones of a lady are discovered when an estate owner opens his labyrinth for a party. Brennan is sure that she has missed a clue and goes back in alone, getting lost in the process. She calls Booth, who goes in to find her and as he is making his way through the labyrinth, he has flashbacks of fun times with Brennan and panics thinking about life without her.
The next is "The Box in the Basement". Clark and his lady friend, Nora, decide to buy a house and discover a box of bones hidden in a dark corner of the basement. Booth and Brennan are together now as a couple and have their first fight.
The last one, (untitled as of now), is a corpse has been found on a cruise ship for honeymooners. Booth and Brennan go undercover as a newly married couple to solve the crime.
