An AI ‘nose’ can remember different scents
Russian researchers are using deep learning neural networks to sniff out potential scent-based threats. The technique is a bit dense (as anything with neural nets tends to be), but the gist is that the electronic "nose" can remember new smells and recognize them after the fact.
Crowdsourced research predicts what molecules smell like
As of now, the only way to tell how something smells is to actually take a sniff. That is to say, there's no observable, scientific measure we know of that can predict how we'll perceive a specific odor. In comparison, things are a little more cut and dried with sights and sounds; because humans use wavelengths to process what they see and hear, we generally agree on, say, how we expect a specific color to look. But scientists now seem to be making progress on the olfactory front: New crowdsourced research has brought scientists closer to predicting a molecule's smell based solely on its chemical properties.
Researchers can now 3D-print nose cartilage in 16 minutes
Doctors have been employing 3D-printed tissue for years now. But even though the hype around 3D bioprinting has raised expectations that it will save lives and shorten donor wait lists, fully functional printed organs are not feasible yet. While we won't be seeing blood pumping printed hearts any time soon, getting a new nose could become easier.
Experimental stem cell treatment causes woman to grow parts of a nose on her spine
Stem cells are seen as one of modern medicine's most promising magic bullets, but that doesn't mean that we understand them. A paralyzed woman from the US has learned this the hard way, after an experimental treatment caused her to grow a nose-like tumor on her back. The unnamed person took part in a trial whereby stem cells from her nose were applied to her spine in the hope that it could repair the nerve damage that led to her paralysis. Unfortunately, the treatment was unsuccessful and, eight years later, the subject found worsening pain in that same area. When surgeons operated, they found a tumor comprised of nasal tissue that was producing a thick substance that was remarkably close to mucus.
Minecraft's latest snapshot has a witchy woman
Minecraft is getting a Halloween-related update in October, and among a slew of other changes (including updated sounds) a new creature is being added to the game. She's a witch! Mojang developer Nathan "Dinnerbone" Adams said the witch will be a ranged attacker, and will use the "Testificate" humanoid model, along with a polygonal nose that will wiggle and twitch.Dinnerbone also hinted at a new animal type, while YouTuber Martyn (aka InTheLittleWood) posted a new video, which shows NPC bats are on their way to Minecraft. They'll spawn not only outside at night, but in any area, under or above ground, if there's a big enough space. They'll also hang upside down, rather creepily.The new update should be out next month, so get your candy bags ready for then.
Beauty Lift High Nose puts the plastic in (and leaves the surgery out of) plastic surgery
Sizable schnoz? Problem proboscis? Looking for a dubious, crapgadgety alternative to costly rhinoplasty? A Japanese company called Omni has a device called the Beauty Lift High Nose that claims it will do the trick. You can get yours for $140 if you dare -- but don't hold out for an Engadget review before placing your order.
The nose knows... how to let quadriplegics move and speak (video)
We've seen quadriplegic transportation directed by brainwaves, speech and even the occasional Wiimote, but your best bet might be to follow your nose. Israeli nasal researchers at the Weizmann Institute of Science unveiled a "sniff controller" this week, that measures nasal pressure to control a wheelchair joystick with surprising precision (see a video after the break) and a specially-developed typing interface. The latter is likely the more important advancement, as Discover heartwarmingly reports at the source link, by giving patients with locked-in syndrome (a la The Diving Bell and the Butterfly) the long-lost ability to speak. Best of all, the technology is inexpensive compared to alternatives on the market; while a Stephen Hawking-esque eye-tracking system can cost tens of thousands of dollars, Weizmann scholars reportedly pieced the prototype together for $358. The device is already being considered for public availability by the institute's technology transfer company, Yeda R&D -- find out just how it works in the full study at our more coverage link.
Artificial nose becomes coffee analyzer, sniffs out KIRF Starbucks venues
Artificial schnozzes have been sniffing foreign objects for years now, but rarely are they engineered to sniff out specific things. A team of researchers from the University of Illinois in Urbana-Champaign have done just that, though, with a new snout that acts as a coffee analyzer. Reportedly, the device can "distinguish between ten well-known commercial brands of coffee and can also make a distinction between coffee beans that have been roasted at different temperatures or lengths of time." The significance here is that this distinction is incredibly difficult to make, and it could one day help coffee growers determine whether batches are as good as prior batches on the cheap. More importantly, however, it could help the modern java hunter determine whether or not they're walking in a corporate Starbucks or one of those "branded" kiosks with two-fifths the menu. Brilliant, right?
NASA's new e-nose can detect scent of cancerous brain cells
NASA's recently developed electronic nose, intended for air quality monitoring on Space Shuttle Endeavour and later the International Space Station, has a rather fortunate and unintended secondary role. In addition to being able to detect contaminants within about one to 10,000 parts per million, scientists have discovered it can also sniff out the difference in odor between normal and cancerous brain cells -- not a new use for e-noses, but certainly one that helps to advance the field. Groups such the as Brain Mapping Foundation, City of Hope Cancer Center, and Jet Propulsion Laboratory have been testing the technology and hope it one day leads to a new understanding of cancer development. We'd also wager it can accurately detect what cologne or perfume you're wearing, another unintended side effect and probably not as fun of a party trick as it seems.

NASA's newest e-nose for ISS thinks you're wearing too much cologne
Electronic noses are nothing new, but it's always interesting when you throw space into the mix. NASA's most recent Endeavor mission has taken with it a third generation e-nose that's the size of a shoebox, where it will act as a detection and warning system for air contaminants. The ISS currently has no system and relies wholly on the astronauts' actual noses. Developed and built by AEMC, the new nose's dynamic range is from less than one part per million to about 10,000 parts per million -- much more sensitive than human honkers. The e-nose has 32 sensors made of polymer films that respond to different chemicals by changing electrical conductivity, and it's capable of both detecting and analyzing what it "smells." The nose is going to be operational on the space station for a beginning trial period of six months, and we have a feeling that its first accomplishment will be to point out that there's something strange about the water.

Researchers developing advanced electronic nose
Creating minuscule devices that can mimic olfactory systems is nothing new, but an international team of researchers are reportedly working to improve an existing design by basing it on metal oxide nanowires. Granted, the actual technology is a bit above our noses, er, heads, but according to Dr. Andrei Kolmakov, the team's aim was to "demonstrate the excellent performance of a practical device made by combining bottom-up fabricated SnO2 nanowires / nanobelts as sensing elements with a multi-electrode KAMINA [e-nose] platform." More specifically, these gurus decided to implement a "completely new morphology of the sensing layer" composed of tin oxide nanowires rather than the traditional thin-film sensing element. Not surprisingly, those working on perfecting the device are hoping to one day have it installed in areas where intelligent sensor systems are used, but we wouldn't overlook the possibility of finding these things embedded in shirts of the future for those paranoid about their freshness.[Via Coolest-Gadgets]
Play DS for a good cause
Not that "enjoying yourself" isn't a good enough cause, but this is for a good social cause. DSMeetup.org.uk, a group that gets together in London for DS multiplayer sessions, is holding a charity tournament on March 10, to benefit Comic Relief, who we had no idea still existed, and who continues to raise money for various causes in Africa.The event is being held to coincide with Comic Relief's "Red Nose Day", which is kind of like Britain's version of the Jerry Lewis Labor Day Telethon, but with more comedians and novelty nosepieces. British readers, feel free to correct us.Participants pay £1 to get into the tournament, and all of the proceeds go to the charity. We admire the DSMeetup group for wanting to do something positive with their DS gaming sessions; the most charitable thing our Game Nights here do are keep us from debilitating, painful loneliness. And even then, only for a few hours.[Via Wonderland]
Researchers catch a whiff of "aroma fingerprints"
While we've already seen just how savvy dogs are at scouting out cellphones, researchers around the globe have teamed up to find out how pups distinguish the aromas that each individual emits, and the result is a highly influential electronic nose. Now if the boys in blue can't track you down via fingerprint, EEG signatures, or just looking at those guilt-filled eyes, it looks like your "aroma fingerprint" just might find you out anyway. The team has uncovered that each human has at least 44 chemical compounds in their odors that can be distinguished, and aside from assisting in identification, can be used in forensic studies to determine true causes behind crimes, deaths, or other misdemeanors. It's even stated that this new technique can assist officials in learning about one's "gender, lifestyle, whether or not they smoke, recent meals, and stress levels." Of course, criminals could be shaking in their boots, but until the scientists find a way to sniff through "deodorant and perfume," we can't exactly count on this being reliable.[Via Spluch]
