NOTE ON POPULAR POSTS

The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

OCEAN ACIDIFICATION HAMPERS REPRODUCTION

As this ScienceDaily article warns, the rising acidification of the ocean looks likely to have a major impact on the ability of marine animals to reproduce.
