Computed tomography (CT or CAT) scans help doctors detect everything from cancer to kidney stones. But some physicians are raising concerns about the safety of such procedures - most notably, an increase in cancer risk. A CT scan packs a mega-dose of radiation - as much as 500 times that of a conventional X-ray. If your doctor orders a CT scan for you or your child, should you think twice...
...install it. The most obvious improvement (and by the way, Firefox claims more than 15,000 improvements - bet you can't name 100 of them) is the "awesome bar," its update to the location bar. You can start typing a keyword in the location bar and Firefox will scan the history file of places you've visited for matching keywords. I typed "flight" in my location bar, for instance, and Firefox pulled up a variety of airline sites I've visited during the past month...
...meantime, Von Ahn has figured out a way to take advantage of all the spare brainpower hundreds of millions of people expend deciphering wiggly letters. He has teamed up with the Internet Archive, a San Francisco nonprofit that uses computers to digitally scan books and put the text online, where it can be accessed for free. When its scanners find a word they can't read, they automatically turn it into a CAPTCHA that gets exported to a website in need of one. A human reads it and transcribes it, and the results get sent back to the scanner...
...still reading this article - and chances are greater if you're older than 34 - you may be wondering whether there's a cure for newstritional disorder.

The new bite-size media model is to reduce the news fat, cut back on content, and create tasty treats that requires fewer mental calories to digest...
...worked out a system where, as I read, I'd highlight different things - descriptions of characters, cool scenes - in different colors. Then I could scan by color for what I needed to find. I'd start sketching real loosely, with pencil on tracing paper. I'd do a series of tracings on top of that, and on top of that, until I had what I felt was a good-looking character. It's really just sketching and re-sketching, and paying attention to the words and descriptions. Harry Potter fans are so in tune. They pay attention to every detail...
