Scientists in the UK have developed a USB stick that can quickly and accurately measure the amount of HIV is in a patient’s blood.

Wax seals have been used for millennia to guarantee a document's authenticity. If you got a letter with an intact seal, you could be assured that what you're reading was legit. The Top Secret USB does the same thing for your digital documents—literally.

I have a drawer filled with USB drives that I've picked up along this windy life of mine but none of them look like Empty Memory, an artsy, almost jewelry-esque USB stick that looks like it's hollow. They only hold 4GB of data but BOY DO THEY LOOK COOL.

The mini Canon 5D DSLR flash drive of the other year has a couple of similarly-statured friends joining him at the flash-storage convention: an IXUS 200IS compact camera and Legra HD camcorder version. Both have the same retractable USB arms and 4GB of storage, but my heart will always belong to the 5D. [Behance via …

Perhaps Etsy seller Newfocus should recycle some of those old Kodachrome film rolls and charge even more than $19 for a 2GB stick, and $24 for a 4GB stick. I'd buy one, and I know plenty of other film-shooters would too. [Etsy via CrunchGear]

You can keep your novelty sushi USB stick—all the cool kids are protecting themselves by backing-up. [Eugene Filatov via LikeCool]

Across New York, there are USB drives embedded in walls, buildings and curbs. The idea is to create an anonymous, offline file-sharing network in public space. The drives are completely public and anyone can plug in to drop and download files.

If you're going to get your laptop stolen by anyone, better hope it's by this Swede, who copied the laptop's data onto a USB stick and sent it to his victim in the post a week later.

It's not pocket-sized, nor can it be lent to colleagues without experiencing a glimpse of fear it won't be returned, but the Voltron Lionforce Defender 2GB USB stick does come pre-loaded with a remastered Voltron episode. Just $30. [Incubot]

It looks and acts like an ordinary eraser until you open it and discover it is also a USB memory stick (and part of a campaign for Alzheimer's awareness). [Ads of the World via Likecool]

Its poor little punched-out eyes blink red with the horror of having LEDs shoved in them, every time it makes a data transfer. Video of the post-life torture after the jump.

The 1GB USB Man may come in gold and silver, but he'll leave with your wife. $90. [gift-library via bookofjoe]

Stick these two on your head and put a kitten tail up your butt to become that weird guy who likes to play pussy when he's home alone. Alternatively, use these as 2GB memory sticks.

All Evangelion nerds (like me) should know exactly what this Entry Plug is supposed to be: the ride Shinji and Rei have that plugs them (in more ways than one) into a gigantic robot. This USB storage version does NOT allow you to destroy Tokyo while protecting it, but it does keep your files safe while you're…

For the world's cheapest man, we present the world's (supposedly) cheapest 64GB USB stick. It's assembled just for you out of the Netherlands, the place where quality (?) USB drives are made. You have the choice of brown or black, which makes perfect sense since this thing's made of leather, and nobody wants a purple…

Rohos Logon Key is a bit of software that can convert any USB key you have into an actual "USB key" to unlock your Mac. The software sits in your login screen and detects the serial number of your USB key (which is unique, but might not be too easy to duplicate) as the identifier to log you in. Quite cool if you need…

Sure, you might loathe Apple with every fiber of your Windows-running being. But look at this iPod USB stick. It's so cute. How can you hate it? It comes in 1GB and 2GB flavors for £19.95 (about $40, damn weak dollar) and £24.95 ($50). Yep, still adorable. Awwww. No? You probably hated Wall-E too. [BoysStuff via Nerd…

USB thumb drives stopped being cool about 10 years ago, but what happens when you stick a microSD card reader on board? It gets cool again, that's what. Kingston's DataTraveler Micro does just that, and even holds up to 4GB of onboard memory inside the thumbdrive itself. The reader can read not only microSD cards, but…
