Because I have a lot of waiting to do today.
1) Big "bounce" hypothesis: Our expanding universe started not from a singularity, but from a very small, very heavy, particle existing at the end of a contracting universe. It makes me think of the universe being a sine wave, and also of the Doctor Who episode (The Satan Pit, I believe) where The Doctor says that you can't have anything "before time". Of course, it's a fairly blind guess. But pretty cool nonetheless.
2) Altruistic rats: When rats are done favors, they pay them back, or, failing that, they pay them forward.
(both were found on Monday.)
I get the feeling that no one much cares about the articles I find. However, I find them interesting, so I will be difficult and keep posting them.
