Think back to an important event in your life: a graduation, a birth, a special Thanksgiving dinner. Chances are you're remembering not only what happened, but also where it happened. And now scientists think they know why.
As we form so-called episodic memories, the brain appears to be using special cells in the hippocampus to "geotag" each event, researchers report in Science. The process is similar to what some digital cameras do when they tag each picture with information about where the image was taken.
The Francisco Villa Public School is a big, cement block of a fortress in an eastern Tijuana neighborhood just south of the Mexico-U.S. border.
Many of the nearby houses are patched together out of discarded materials, like old garage doors. The roads are unpaved and deeply rutted.
The school bell pierces the dusty air as girls in pink jumpers and boys in navy sweaters stream out of class. For 45 middle school students here who were born in the United States, the sound of the bell is one of the few things that are familiar.
Let's face it, while Thanksgiving get-togethers can be joyful, they can also be stressful. And if you're gearing up for a family gathering right now, you're likely awaiting the arrival of a few loved ones who may be a little hard to love sometimes.

On a recent Saturday morning, Jerrine Sanford traveled half an hour from the small town of Runnells to get her insurance questions answered at a hospital-run event.
Sanford, 47, is out of work because of a back injury. She's worried about the law's requirement that everyone have health insurance or pay a penalty.
Israeli Prime Minister Benjamin Netanyahu is one of the most prominent critics of the U.S. deal with Iran. While President Obama calls the agreement a breakthrough, Netanyahu calls it a "historic mistake." It's far from the first time the Israeli and American leaders have clashed.
Barack Obama and Benjamin Netanyahu took charge of their countries within a few months of each other. They were hardly a matched pair.
Amanda Maia was visiting Rio de Janeiro for the weekend earlier this month with her mother. It was a sunny day and so they went to Ipanema beach to catch some rays. She says she noticed a few groups of kids.
"There were lots of gangs, about 10, 15 children each; they were about 10 or 12 years old," Maia recalls.
At first, she says, they were just roaming the streets, checking people out. The ones she saw were smoking marijuana, too.
