Small children can be particularly vulnerable when natural disasters strike. They may be unable to understand what turned their lives and those of their families upside down. They may be confused, angry, fearful or saddened -- and that may manifest itself in behavior such as bed-wetting, sleep problems and separation anxiety, according to the Federal Emergency Management Agency.

MED-Math-Pain

You're at a big group dinner and it's time to pay up, to divide the total and multiply a certain percentage for the tip. How many people tense up and say something like, "Oh, I'm so bad at math"? Fear of math is everywhere - in the adult world where there aren't official pop quizzes, and in schools where the next generation of scientific problem-solvers are struggling with homework. Researchers report in a new study in the journal PLoS One that this anxiety about mathematics triggers the same brain activity that's linked with the physical sensation of pain.

Computers are evolving.

These machines aren't just taking over human tasks. Computerized systems are also taking on more human characteristics. As technology gets more advanced, how will our relationships with it change?

Blaring ads, arguments with co-workers, family and (former) Facebook friends. The cold nip in the air is already driving you over the edge, but presidential elections really make you want to bury your head in the sand. No need to flee the country without voting. The State Department and the Federal Voting Assistance Program offer guidance for U.S. citizens. But if you don't want to hear any more about it after that, a warm weather getaway might be just the ticket. If the elections don't go your way, hold onto this list. These places are great ex-pat havens.

TRAVEL-Post-Sandy-Travelers

Andrew Avis, a construction safety consultant on vacation from the United Kingdom, has been stranded in New York since Saturday. He and his wife, Sandy, marked their 38th wedding anniversary on the Amtrak train from Orlando on Friday night - but were planning to splash out more lavishly when they arrived in New York, before traveling on to visit friends in Rhode Island. Instead, they found their train out of New York on Sunday was canceled and were forced to hole up in the city as it braced itself for the incoming storm. "I wasn't anticipating coming here with two Sandys," said Avis, 64.

Halloween-All-Year-Round (with art and fact box: Halloween-By-The-Numbers)

When the jack-o'-lanterns have all burned out and the candy wrappers have been swept away, Jim Warfield won't be hanging a "closed" sign in the window of the Raven's Grin Inn, the haunted mansion he runs in the small Illinois town of Mount Carroll. With its twisted passageways, secret tunnels and reported sightings of a "Lady in White," the eerie 19th-century house draws visitors all year long -- and Warfield accommodates them.

FEA-Disaster-Survivors-Advice-Sandy

Devastation is devastation, whether a hurricane rips up your home or a tornado takes the person you love most in the world. It's loss, shock and confusion. It's anger and sadness and resentment. It's being flustered like you've never been flustered before. But it's going to be OK: Take it from the people who survived Hurricane Katrina and the Missourians from Joplin whose town was leveled by the worst tornado in U.S. history. They want Sandy survivors to know a few things.

Photographers and artists have a long relationship with art books as vehicles that share their work with audiences beyond the gallery circuit. But do those books have a shelf life beyond their era?

FEA-Bullying-Fight-Back

Fall is upon us, and that means the school year is in full swing. Along with the stress of homework assignments and extracurricular activities, unfortunately some students bear an additional burden -- bullying. October is National Bullying Prevention Awareness Month, pushing the issue to the forefront of the nation's consciousness. Educators and legislators are under pressure to prevent bullying, and many schools are implementing programs such as A Classroom of Difference, Steps to Respect and Positive Behavior Intervention and Supports that teach empathy, interpersonal skills and respect for those who don't fit into the mainstream. But not everyone agrees with this approach to managing bullying.

FEA-Boomers-Dating-After-50

I never thought I'd be here, but here I am. And let me tell you -- dating at midlife just ain't what it's cracked up to be. What's that, you say? Internet dating is all the rage! There's no stigma anymore. It makes perfect sense. With our hypercharged careers, family responsibilities, keeping up with the news and working out -- who has the time to meet people anymore? Forget singles bars. What woman in her 50s really enjoys meeting strange men at bars? Oh, wait. Most Internet "first dates" begin at bars. With strange men. Still, the draw is strong. Everybody seems to know somebody who's met her significant other online.
