Who doesn't want to fly for free? But can you really get where you want to go using your frequent-flyer miles? To find out, Consumer Reports asked staffers to try booking round-trip tickets using their frequent-flyer miles with nine programs. Whatever you do, Consumer Reports says don't hoard frequent-flyer miles. You run the risk that they'll expire. Consumer Reports says that if you can't book a seat using miles, try calling the frequent-flyer service desk. Agents can sometimes find seats that you can't.
A fingerprint may someday be enough to board an airplane if Alaska Airlines' new biometric scanners can get past security concerns. The company has installed the device at its private lounge at Sea-Tac Airport to gauge the response by frequent flyers. Scanning digits could save time not just at passenger lounges but also bag drops and other airport checkpoints. However, the devices would have to be foolproof to be accepted by the Transportation Security Administration, which right now requires passengers to carry drivers licenses or other forms of identification.
New research shows that when it comes to engagement rings, bigger isn't always better. Researchers at Emory University studied 3000 couples, comparing the size of the engagement ring to the length of their marriage. The results are illuminating.
Some schools are trying out a new teaching method that challenges old concepts like homework. In flipped classes, the students study the topic at home on their own using lessons (video or otherwise) prepared by their teachers. The students then do practical work (or what used to be their homework) in class in the hopes that having the teacher present during the application learning process will help students who might get stuck, give more one on one time with teachers encourage the completion of coursework.

We all have ideas in our head of what we wish we look like, but usually no one else finds out. One photographer figured it out, using a brain-scanning headset. He took simple headshots of people, and then made dozens of altered versions of each person. He used editing software to manipulate their looks, making edits according to "scientifically established canons of beauty," or going against those. Then, he connected each subject to an EEG headset, which recorded their neuroelectric responses, while they watched a slideshow of themselves. The brain scanner tracked their immediate emotional reactions. So without even asking which photo they liked best, the computer knew.
