Who hasn't turned a camera around at arm's length to snap a picture to send to friends or family? It always seems like it takes a few tries to frame the shot just right to capture both you and that awesome mountain summit behind you.
It's been a mixed year for Alzheimer's research. Some promising drugs failed to stop or even slow the disease. But researchers also found reasons to think that treatments can work if they just start sooner.
Scientists who study Alzheimer's say they aren't discouraged by the drug failures. "I actually think it was a phenomenal year for research," says Bill Rebeck, a brain scientist at Georgetown University.
Now that the Christmas feast is over, you may be looking at all the extra food you made, or the food that you brought home from the store that never even got opened.
And you may be wondering: How long can I keep this? What if it's past its expiration date? Who even comes up with those dates on food, anyway, and what do they mean?
Here's the short answer: Those "sell by" dates are there to protect the reputation of the food. They have very little to do with food safety. If you're worried whether food is still OK to eat, just smell it.
An east Texas landowner was so determined to block the Keystone XL pipeline from coming through his forest that he took to his trees and built an elaborate network of treehouses eight stories above the ground.
"It popped into my head a long time ago, actually," says 45-year-old David Daniel. "If I had to climb my butt on top of a tree and sit there, I would. It started with that."
It turned out to be Daniel's last stand in a long battle against the Keystone XL, a pipeline project that would bring oil from Canada all the way to refineries in the Texas Gulf Coast.
With Christmas upon us and the New Year just around the corner, we're taking a two-week break from regular posting on 13.7. You may still see a few "micro posts" over the next two weeks. But we won't be back to our regular schedule until Monday, January 7. We hope to see you again then.
