scanning

There's a quaint concept that seemingly every technology company dismisses as outdated.

It's called opting in.

Should you not be familiar with it, it's the notion that you ought to choose before, say, all the people in your address book are contacted by a company they've never heard of.

And wouldn't it be lovely to have a choice over whether your kids should have their irises scanned, as they get on their school bus?

The parents of around 750 kids in several Florida schools never got that choice -- because of what might be politely … Read more

You've got a scanner, but to scan images into your PC, you need software like VueScan from Hamrick Software.

VueScan is free to try, though the trial version places a watermark on saved images. The free trial might also support fewer devices, though the list of supported devices is so … Read more

Google Now's interface sensibilities are spilling over into other Google services.

The latest recipient of a healthy dose of the Now virtual assistant is Google Drive, which updated its Android app on Wednesday with several new features.

A new Scan feature lets you back up and track important receipts, business cards, and documents by using existing optical character recognition (OCR) tech already in Drive. Choose Scan from the "Add New" menu, take a photo of the document, and Drive will automatically turn it into a searchable PDF.

The new interface leverages the Cards look from Google+ and … Read more

Thanks to the magic of dissection, we have a pretty good idea of the changes that occur when a caterpillar spins its chrysalis and enters its metamorphosis -- the developmental stage that sees it move from the juvenile larval stage to the gorgeous adult life of a butterfly.

However, as you might have already guessed, dissection destroys the specimen, meaning that researchers are unable to follow the full development of a creature. We do know that the caterpillar will use enzymes to break down some of its proteins to reform; Scientific American called this a cocoon full of "caterpillar soup." However, scientists have performed research revealing that while some breakdown occurs, the idea of caterpillar soup is mostly wrong (but still gross).

Using micro-computed tomography, or micro-CT scanning, which uses X-ray imaging to re-create 3D cross-sections of the scanned object, Tristan Rowe and Russell Garwood from the U.K's University of Manchester and Thomas Simonsen from London's Natural History Museum have discovered exactly what happens to a painted lady butterfly inside the chrysalis. … Read more

For those who want a scanning program that adds features over those of native Mac applications, VueScan for Mac does just that--and it performed well in our tests.

VueScan for Mac comes with a free trial version that limits the scanners available for use. The full version costs $39.95 to unlock. The download completed as quickly as expected via a high-speed connection. A user guide was available as a link to the developer's Web site, which was a helpful feature. Support for updates also appeared to be available. The main menu had a dated design, but was functional. … Read more

If you're looking to attract attention, setting a Guinness World Record is probably a good way to start.

That was the goal -- attracting attention, that is -- for a group of IBM Research scientists who recently set out to make what turned out be the Guinness World Record-certified smallest stop-motion film ever.

Called "A Boy and His Atom," the animated film features a small boy having a good old time as he bounces around, playing catch, and dancing. The twist? The film was shot at the atomic level and features 130 atoms that were painstakingly placed, atom by atom, as the researchers shot 250 individual frames. The images were created at a temperature of negative 268 degrees Celsius and were magnified 100 million times. … Read more
