There was the time he fell "headfirst on a marble floor" and got a concussion, the day someone stole the family car ("my dad had to chase it down the block"), or the morning he found a black bat (the furry kind) in the house.<p>But Francis looks puzzled when his mom, Joanne Csedrik, asks him about a family trip to the Philippines when he was 3. "It was to celebrate someone's birthday," she tells him. "We took a long plane ride, two boat trips," she adds.

Chances are you're remembering not only what happened, but also where it happened. And now scientists think they know why.<p>As we form so-called episodic memories, the brain appears to be using special cells in the hippocampus to "geotag" each event, <a href="http://www.sciencemag.org/">researchers report</a> in <em>Science</em>.

Cigarettes Or The Nicotine Patch? http://wcbe.org/post/pregnancy-whats-worse-cigarettes-or-nicotine-patch Lots of studies have shown that cigarette smoke isn't good for a fetus. So many pregnant women use nicotine gum or skin patches or inhalers to help them stay away from cigarettes.<p>A few years ago, Megan Stern became one of those women. "I smoked heavily for the first seven weeks of my pregnancy because I didn't know I was pregnant," she says. "It was an accidental pregnancy, and I found out while I was in the emergency room for another issue."<p>Stern, who lives in Massachusetts, was 21 at the time and had been smoking since she was 14.
