Corkscrew nanopropellers may one day deliver drugs internally

Clearly, vaccinations are so three years ago. As the race continues to find the best, most mobile internal transportation device for delivering drugs to remote places within the body, Peer Fischer of The Rowland Institute at Harvard University has teamed with colleague Ambarish Ghosh to concoct the wild creation you see to the right. The glass-derived nanopropeller was designed to move in a corkscrew motion in order to plow through syrupy, viscous liquids within the human frame. The device itself is fantastically small, measuring just 200 to 300 nanometers across at the head and 1 to 2 micrometers long. Fischer points out that each of these can be controlled with a striking amount of precision via an external magnetic field, though we don't get the impression that they'll be on to FDA testing in the near future. Ah well, at least our gra, er, great-grandchildren will be all taken care of.

Engadget arrives at E3 2009!

We've landed in somewhat sunny Los Angeles, just in time to watch the (de)construction of a mountain of miscellany in front of the LA Convention Center's South Hall. It's gonna be a long week for us covering all the hottest hardware and gaming peripherals, including DJ Hero, Beatles Rock Band, and we're thinking a few non-surprises from the likes of Microsoft and Sony. We've joined forces with our cohorts at Joystiq in creating a dedicated E3 2009 hub to satiate all your game news needs, as well as keep track of when all the keynotes are going down -- but of course if you're just interesting in the Engadget side of things, you know where to look.

Things kick off tomorrow -- June 1st -- with Microsoft's press conference, and we'll be there blowing it out live. Here's when all the fun begins:

07:25AM - Hawaii
10:25AM - Pacific
11:25AM - Mountain
12:25PM - Central
01:25PM - Eastern
05:25PM - GMT
06:25PM - London
07:25PM - Paris
02:25AM - Tokyo (June 2nd)

Gametrak Freedom Xbox 360 motion controller up for pre-order with Squeeballs

We get the feeling this isn't the motion sensing surprise that's likely in store for Xbox 360 fans at E3, but it's still great to see this controller moving beyond the hype stage. After being spied late last year and detailed around two months ago, the Gametrak Freedom motion controller is now listed at GameStop with an October 15th ship date. The controller, which will come bundled with Squeeballs: Island Party for the Xbox 360, is already up for pre-order, promising gamers who shell out $69.99 a grand total of 11 motion sensing party games. Unfortunately, there's no word on how much extra Freedom sticks will run, but based on the price of this kit, we'd wager not much.

[Thanks, Josh]

MSI’s Cheap Desktop Suffers From Performance Anxiety

Is there an answer for the floundering desktop? Turns out there is. MSI thinks there is. They've taken the guts from one of its netbooks, slapped it into an all in one chassis, and thrown a touchscreen in the mix. They call it the Wind Top.

Acoustic superlens could mask ships from sonar… in theory, anyway

Man, the mad scientists are really on a roll of late. First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.
