Sara Terry's first clue that something was wrong with her son, Christian, came just three weeks after he was born.
"We went to check on him, just like any parents go and check on their kids just to make sure they're breathing," says Terry, 34, of Spring, Texas. "And we found him in his crib, and he wasn't breathing. He was blue."
She and her husband were horrified. They rushed Christian to the hospital and learned he had several medical problems.
By now, everyone's heard of Kickstarter, the website that lets people with an idea or project ask other people to contribute toward realizing it. It's called crowd funding, and this summer's big success story was musician Amanda Palmer. She raised more than $1 million to produce her new album. But crowd funding doesn't work for every musician every time.
It's taken as a given that American voters in 2012 aren't as concerned about foreign policy as they are the domestic economy.
It's also accepted as true that on matters of foreign policy, President Obama has an advantage over his Republican challenger, former Massachusetts Gov. Mitt Romney, who lacks significant firsthand foreign policy experience.
But Romney has made it a point lately to show that he's not ceding foreign policy and national security to Obama.
Arctic sea ice is in sharp decline this year: Last week, scientists announced that it hit the lowest point ever measured, shattering the previous record.
But it turns out that's not the most dramatic change in the Arctic. A study by Canadian researchers finds that springtime snow is melting away even faster than Arctic ice. That also has profound implications for the Earth's climate.
