A question to all you (science) bloggers

We are getting close to the end of the year, and I have been wondering what my fellow bloggers, perhaps especially science oriented bloggers, think about something.

What has been the best science moment of 2007, and what has been the worst?

Here I am thinking very broadly. It can relate to science discoveries, news, policies, frauds, and even issues further from the field of science (such as the Republican Presidential candidates showing if they rejected the theory of evolution).

If you have a good answer, then leave a comment, or link to this post from where you've posted the answer.

It could be interesting to see what everyone thinks.
