The quest for the ultimate artificial nose is still underway, and thanks to a major breakthrough by the folks over at MIT, it might be sooner than later that we're all unwrapping stylish sniffers under the Christmas tree. More importantly, the fruits of MIT's RealNose project could replace drug and explosive-sniffing dogs as well as detect certain medical conditions via the odors emitted. Up to now, the tricky part of studying the sense of smell has been in isolating proteins (olfactory receptors) to get a good look at how they work. But in this latest development, researchers are now able to produce specific receptors using wheat germ. Engineered mammalian cells can be used to the same effect. What makes this so great is, while the human nose is relatively limited in what it can detect, this discovery could unlock the potential to detect an almost infinite range of odors. G.I. Joe with "action nose" here we come.

It's been a long road plagued with disappointments and major mishaps, but SpaceX (and founder Elon Musk) has finally made history -- on Sunday the company's Falcon 1 rocket reached orbit. After three attempts to bring the dream to life, the space exploration company succeeded in putting the first privately-developed rocket into space. The liftoff was seen live during a webcast, and the company's site was continuously updated with news, including a message written at 16:26PDT reading:

T+0:08:21 Falcon 1 reached orbital velocity, 5200 m/s

Nominal Second stage cut off (SECO) - Falcon 1 has made history as the first privately developed liquid fueled launch vehicle to achieve earth orbit!!!!!!

Needless to say, after the trials and tribulations SpaceX has gone through (including the loss of Star Trek star James Doohan's ashes), this must be welcome relief... as well as the birth of a potentially lucrative new enterprise. Er, no pun intended.

Some things just shouldn't ever be plugged into your USB port. Not even that dusty, never-to-be-used socket in your 16-port USB hub. The gadgets you'll see below are among the worst of the worst, with some being so awful, they almost deserve a purchase just to give you a laugh live and in-person. Seriously, just listen: an actual "thumb" drive, a USB key doused in cabbage, a mousepad that doubles as a Lars Ulrich-approved drum kit and a USB Hollywood Film Kit for those still in denial over that acting school rejection letter. There should really be laws against some of this rubbish, but since there isn't, we're putting it to you -- drop your vote in below to let us know which of the following gizmos reeks the most. Good luck down there.

Thanks, MIT. Why don't you just make the rest of the world feel a little more useless. Every week or so, we're forced to stare at yet another amazing invention coming from your doors; to be frank, it's just downright unfair. All childish angst aside, the latest idea to come from the institution is one that could certainly be put to good use: a self-sustaining sensor network that taps into trees for power in order to continuously monitor forests for threats of fire. Moreover, the concept could be applied in other scenarios as well -- to detect potential threats such as smuggled contraband along a nation's borders, perhaps. Testing of the wireless sensor network (developed by the appropriately named Voltree Power) is scheduled to begin next spring, and we're hearing that pot-sniffing turtles may even be brought in to create a completely natural self-policing environment.

When you're caught between the lines of dueling mercenary armies, trapped in a rapidly aging body that doesn't quite react the way it used to, you need a reliable side arm to protect yourself. That was Solid Snake's situation in Metal Gear Solid 4: Guns of the Patriots, his chosen weapon the Silver Wolf pistol, recreated here in as a Japanese fan's stainless steel and rubber band DIY masterpiece. Constructed of numerous cross-drilled plates and featuring both a laser sight and integrated flashlight, the result looks to be impressively accurate and likely quite painful, as you can see for yourself in a video just below. Bonus reloading footage included!

We'll be honest -- Dave has run into a magnificent problem to have, but it's still an issue in need of an answer. And before you get too engrossed, may we remind you that you can send in questions of your own to ask at engadget dawt com.

"I live in Canada and have relatives visiting Taiwan in the near future. What hawt Asia-only, non-igloo-related gadget should I ask them to grip for me? Thanks!"

We're going to take the liberty of expanding this question to involve all of Asia, given that quite a few others are probably headed to Akihabara in the foreseeable future. So, what's the best gizmos(s) to pick up if heading over to the other side for what may be the first and last time ever?

We always thought that the RIAA's first-ever filesharing trial victory against Jammie Thomas was a little suspect since the labels weren't required to prove that Thomas even had Kazaa installed on her machine or was the person using the account in question, and it looks like the court agrees -- it's just declared a mistrial and set aside the $222,000 judgment on the grounds that simply making copyrighted works available for download does not constitute copyright infringement. That's a huge decision -- the "making available" theory is the basis for most of the RIAA's legal arguments -- and it means that the RIAA will now have to prove the unauthorized transfer of each song it wants to collect damages on at the new trial. We'll see what effect this has in the broader sense -- we've got a feeling we're in for a slew of appellate decisions on both sides of the "making available" debate -- but for now it looks like the good guys are finally starting to score some points.

Elderly? Enfeebled? Just plain clumsy? Tokyo-based Prop has your back. Its newly announced personal, wearable airbag looks like a cool fanny-pack and weighs a mere 1.1 kilograms (2.4 pounds) -- but springs forth in one-tenth of a second when sensors detect you're headed for the floor, protecting your head and ass with two inflated bags that contain 3.9 gallons of gas each. Similar to the various airbag-equipped suits already used by some motorcyclists, the airbag is yours for a cool ¥148,000 ($1,400). Or you could just not fall down.

We'll warn you in advance, this is only for those who dig the weird, all things Stephen Hawking or clock-making in general. This £1 million ($1.83 million) timepiece took seven years to completely construct, and the initiative was led by inventor John Taylor who designed it in tribute to John Harrison (only the world's greatest clockmaker, it's said). The bizarre Corpus Clock visually explains that it relies on grasshopper escapement to function, and to let you know that time can never be regained once lost, that beast on top actually gobbles down time every 60th second. Oh, and every hour, on the hour, the sound of a "chain dropping into a wooden coffin" is played to really pound home the "time is a destroyer" concept. Thanks for the reminder, Dr. Grim.
