- Duke University physicists test first air-based acoustic invisibility cloak
Firmly departing from the Stuff Of Dreams category, Duke University physicists have successfully tested an acoustic cloaking device that fools sound waves while looking nowhere near as scifi as you’d think. Layering nothing more than a bunch of hole-punched plastic sheets — known as meta-materials, for those curious — atop a ten centimeter long block of wood, highly-directed sound in the 1 – 4kHz range bounced right back into the ether none the wiser. The cloaking tech owes some of its origin to the math behind transformation optics — and maybe to the Duke team, too. Besides allowing defense department bunkers to erupt into silent applause, the research should prove useful in the construction of future concert halls. DIY hobbyists, let us know what you can rig up with some trash bags.
[Thanks, Drew]

BBC News | Email this | Comments - Apple product managers respond to Final Cut Pro X criticism
During our call to discuss Final Cut Pro X earlier this week, an Apple product manager boasted about the product’s low price, media management, and ground-up redesign. Unfortunately, when starting from scratch, developers seem to have overlooked a few features that professional users have come to depend on, prompting widespread backlash — both on internet forums and even on Apple’s own App Store, where the $300 download-only app currently has a rating of just 2.5 stars (out of five), including nearly 500 one-star ratings. (Note: you must purchase the app before submitting a rating or review.) The New York Times spoke to product managers about these issues, which include an inability to import old FCP files, no multicamera editing, no support for RED cameras, and no ability to specify QuickTime export settings, among many others. Apple says there are (pricey) workarounds available, or fixes on the way for all but the first issue, but head over to the source link for the full rundown at NYT.

If you’ve been eagerly anticipating the arrival of the latest shape-shifting slate, it looks like you’re just going to have to wait. Fujitsu’s just announced that it will postpone the release of the convertible TH40/D tablet — the Windows 7 slide-out was originally slated for a late June debut in Japan. Unfortunately, the outfit’s being rather tight-lipped when it comes to details, saying simply that the holdup is due to “development delays.” Of course, we’ll keep you posted with details if / when Fujitsu decides to open up.
