And congrats to yesterday's winner, Mandie on her Debbie Downer fact. After working our way through a heap of terrific entries, her submission: "A 'downer' is a farm animal that is too sick or injured to stand and walk" left us positively, well, negative. We'll be sending her a mental_floss tee, and using that comment to spur awkward pauses in plenty of conversations this holiday season.

I don’t know what this is, or how to adequately describe it. It's pretty and interactive. It’s from Adobe Japan, and I don’t read Japanese. If you do, maybe you can find out something about it. Go take a look. Link -via Grow-A-Brain

The owner of a Christmas tree farm in east Tennessee found that someone had sawed off the tops of 28 large Christmas trees that were ready for market. The thief took about six feet of each tree, leading authorities to believe they will be sold as whole Christmas trees. The damaged Frasier firs would have been sold for $100 to $150 dollars each to organizations and businesses with high ceilings. http://www.breitbart.com/article.php?id=cp_fj4drqn8h37&show_article=1&catnum=9 -via Fark

Scientists have announced the discovery of a dinosaur “mummy”, a dried hadrosaur with much of its skin, tissue, and bones intact. The find was made in 1999 in North Dakota. The presence of tendons and ligaments give researchers new insight to how dinosaurs moved. Although the hadrosaur was 35 feet long and weighed 35 tons, they estimate he could run up to 28 miles per hour, faster than a T. rex! Link to story. Link to video report.

Writer and photographer Shreve Stockton took in a baby coyote when his parents were shot for killing sheep in Wyoming. She is documenting Charlie’s life with her and Eli the cat on the blog The Daily Coyote.

If Charlie demonstrates the need or desire to be out in the wild, there are places around here I could safely set him loose. There’s no question he would survive in the wild just fine - his instincts are very intact (more on this later), and though he is gentle and attached to me and to MC, he is afraid of other people.

From the beginning, I have made the commitment to let Charlie decide his destiny; to do right by him without attaching my own desires to the outcome or interfering with human logic. You can join me in seeing what unfolds.

MC refers to a coyote expert who is helping with Charlie. Scroll down the blog and check the archives for adorable baby pictures. Link -Thanks, Bill!

In a study at Tokyo University, 5-year-old chimpanzees displayed better short-term memory than college students!

That challenges the belief of many people, including many scientists, that "humans are superior to chimpanzees in all cognitive functions," said researcher Tetsuro Matsuzawa of Kyoto University.

"No one can imagine that chimpanzees - young chimpanzees at the age of 5 - have a better performance in a memory task than humans," he said in a statement.

Matsuzawa, a pioneer in studying the mental abilities of chimps, said even he was surprised. He and colleague Sana Inoue report the results in Tuesday's issue of the journal Current Biology.

Researchers believe that relative youth helped the chimpanzees, so the next step is to match the chimps against young children. http://news.wired.com/dynamic/stories/C/CHIMP_MEMORY?SITE=WIRE&SECTION=HOME&TEMPLATE=DEFAULT&CTIME=2007-12-03-12-
