then this will do
$result = mysql_query ("SELECT *
From news
where (BULLS = 1 or CHC = 1 )
order by id desc");
and you could then have
$result = mysql_query ("SELECT *
From news
where (BULLS = 1 or CHC = 1 )
and newsdate < now()
order by id desc");
where i've added a column called newsdate which might record the date an item is released, so only show the items which have been released.
So the second query will show any released news from either bulls or christchurch - check out how I've used the brackets.
