- 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.

AppleInsider | The New York Times | Email this | Comments - Fujitsu delays TH40/D release, puts slide-out tablet dreams on hold
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.

Samsung reportedly considering switching the base S Pen tech so it will work on the Galaxy Fold3
Rumors suggested that the Galaxy Fold2 will come with an S Pen but that didn’t happen. The Elec quotes UBI Research, which says that Samsung will try again for the third generation foldable, though it may need to switch to a different technology. The Galaxy Notes use Electo-Magnetic Resonance (EMR), which works with a passive stylus and is generally cheaper, with good accuracy and low latency compared to Active Electrostatic Solution (AES) styluses. However, Samsung reportedly ran into issues with integrating the EMR digitizer with the Ultra Thin Glass (UTG) and making it flexible,...
Samsung Galaxy S21+ CAD renders show the same camera as the S21 and a flat screen
The trio is complete – we saw CAD-based renders of the S21 and S21 Ultra earlier this week, now 3D schematics of the Samsung Galaxy S21+ have surfaced as well. What they show is that the vanilla and the plus model will continue to share a camera, only the Ultra will get a fancier setup. This new camera island appears to be part of the metal frame that surrounds the phone. And while the back glass has some bevel to it, the front is flat – just as it is on the base S21. The bezels around the display are said to be of equal size on all four sides. Samsung Galaxy S20+ CAD-based...
Microsoft’s Surface Duo now starts at $1,199

It originally retailed at $1,399 for the 128GB storage variant but is now listed at $1,199 instead. The 256GB trim is also down $200 to $1,299. There’s no information as to how long these offers will be valid. Surface Duo pricing We’ve recently seen reports of the dual-screen foldable’s lackluster build quality and it’s certainly not easy to repair one either. It’s also noteworthy that Microsoft is offering its Accidental Damage...
