Like parents of twins, wildlife biologists can easily differentiate between similar-looking creatures by noting slight differences that an outside observer would miss. But in the wild, it can take some time to locate the right animals so they can be identified.
A new algorithm can scan zebra photos like they were bar codes, helping researchers track individual animals more easily.
Is your latest photo just too great to show on a small touchscreen? Gather up all your mobile devices and old computers and stitch them together. If they can connect to the Internet, the Junkyard Jumbotron has you covered.
Critics of the selection that's often involved in assisted reproductive technology – picking a 5’10”, blond-haired, Ivy League grad egg donor, for example – say it turns conceiving a baby into a shopping exercise.

Bar codes in the supermarket might face extinction sooner rather than later, if radio-frequency identification (RFID) tags can cost just a penny apiece, rather than the dime or more they currently run. Now South Korean researchers say they have the technology to print RFID circuits on plastic film, courtesy of nanotube-containing inks, Technology Review reports.
