Because they're brutish and sweaty, most men don't have a problem with their phone's naturally metallic musk, but "20 to 40 year-old women with a well-developed sense of fashion" apparently do. That's why Fujitsu has announced the F-022 -- a glittery flip phone designed for females who demand slightly more from their handheld's olfactory offerings. Developed in collaboration with Japanese accessory maker Folli Follie, this bejeweled little bauble comes with a "detachable fragrance chip" that allows users to mark their tech territory with the perfume of their choice. Just spray the chip with a dab of your scent, latch it on to the phone, and every conversation you have will end up smelling like roses. The F-022 goes on sale in China on June 24th, but for more information, just follow your nose to the PR, after the break.

We're not entirely sure why people keep trying to bring back Smell-O-Vision, although Keio University's success in printing scents using a modified printer gives us hope that this sort of thing might someday be somewhat feasible -- and useful. It works by using an off-the-shelf Canon printer that's been given a "scent jet," Kenichi Okada told New Scientist. "We are using the ink-jet printer's ability to eject tiny pulses of material to achieve precise control." The scent dissipates quickly, after one or two human breaths. And while specific scents can be printed, there is as of yet no way to build a general purpose device. According to the University of Glasgow's Stephen Brewster: "We don't yet know how to synthesize all the scents we want. There is no red-green-blue for smell -- there are thousands of components needed." That's OK with us. In our experience, it's usually better that people keep their smells to themselves.

We're glad you're using a bike helmet (and we're glad you've opted for that really scary one we first saw in 2007). You do realize, however, that the more blows to the head you receive, the less effective the headgear is, right? Researchers at Germany's Fraunhofer Institute have developed a manufacturing process that injects microcapsules containing malodorous oils into the helmet itself, causing it to stink when damaged -- alerting you that it's time to replace it (and making it difficult to try and make do with a less than safe one, at that). Indeed, the process, which a thick foil made of polypropylene to house the microcapsules, extends to other products as well, including: pressure hoses, water, and gas pipes (in which case the odor can be detected by automated "smell sensors"). As for the lids, they're still trying to decide exactly which scent to use, but we have a suggestion -- smelling salts. Seems logical, right?

Scientists in Germany have genetically engineered fruit fly larva to 'smell' blue light -- and apparently it smells like bananas! According to a paper published in Frontiers in Behavioral Neuroscience, researchers at Ruhr-Universitaet-Bochum were able to splice a gene for a light-activated protein into cells in the olfactory system. Depending on which cell was spliced, the larva perceived the blue light as smelling like anything from bananas to marzipan or even glue. The scientists used thin electrodes to detect the light-activated neurons, and it is hoped that research in this area will lead to similar procedures that don't harm living animals. Now that they've perfected modding Drosophila larvae, the scientists say they'd like to move on to adult fruit flies. Which is cool with us -- just as long as they don't repeat Seth Brundle's mistakes.
