The interesting thing is that the *promoting* of these news stories has happened this year. For a number of the items, this is actually old news.
The mummified dino was big news in paleontology awhile back -- the scan is newly presented on the Internet, but was conference and news thread news
awhile ago. And this isn't the first soft tissue they've found from T-rex (or other dinos), either.
The chimp spearmaking was fascinating but raised a lot of questions (and we've seen examples of wars and toolmaking in chimp culture.) I think the
stem cell research is the one that I like best. They've been working on this for awhile, and it's satisfying to see public announcements of the
progress.
But I have to admit that my sentimental favorites are all the news stories about the new "tricks" that the Japanese are teaching robots. They're
pushing a lot of machine and social boundaries and there's some interesting new directions (and social questions) in the making.
