From Ars Technica: DoJ on Apple e-book pricing: two wrongs don’t make a right

The US Department of Justice says it plans to move forward with its proposed settlement with some e-book publishers, despite the “self-serving” comments submitted by Apple. In a 64-page response (PDF) to the comments it received on the settlement, the DoJ reiterated its reasons for suing Apple and publishers, accusing Apple of continuing to offer solutions that are “contrary to the public interest.” That’s a no-no, even if the old system pushed by Amazon was a “monopoly.”

When the DoJ first sued Apple, Hachette, Harper Collins, Macmillan, Penguin, Pearson, and Simon & Schuster in April of 2012, it said the companies had actively conspired to raise e-book prices. This allegedly forced consumers to “pay tens of millions of dollars more for e-books than they otherwise would have paid” since the iPad’s launch in 2010, both as a result of the iBookstore’s prices and Amazon’s eventual decision to adopt the same “agency model” pricing scheme that same year.

Three of the publishers—Hatchette, HarperCollins, and Simon & Schuster—immediately agreed to settle with the DoJ, leading to a slew of commentary being submitted from the public, publishers, and even Apple. And now that the comment period is over, the DoJ appears to feel even more strongly about its original complaint. In its response, the DoJ reiterated that it conducted a “lengthy investigation” into the e-book price increases of 2010 that “uncovered significant evidence that the seismic shift in e-book prices was not the result of market forces, but rather came about through the collusive efforts of Apple and five of the six largest publishers in the country.”

From Ars Technica: Tri-band WiFi chips for 7Gbps speed coming from Marvell, Wilocity

One of the biggest changes ever made to WiFi is coming in the next year with a new standard supporting the 60GHz band, powering much faster transmissions than are possible in the existing 2.4GHz and 5GHz bands. All that’s needed are some chips, and products to put them in.

Slowly but surely, the chipmakers embracing 60GHz technology are making their plans known. The latest is Marvell, which today announced a partnership with startup Wilocity to make tri-band chips that will use all three bands. That will allow consumer devices to connect to existing WiFi networks while also taking advantage of the super-fast 60GHz band for high-speed data transfer and high-quality media streaming. Under the developing 802.11ad standard, 60GHz transmissions can hit 7Gbps.

Wilocity already has a partnership with Qualcomm Atheros, Qualcomm’s networking subsidiary, to build tri-band chips. Those are expected to come out by the end of this year and focus on the PC notebook market—for example a laptop bundled with a remote docking station. The partnership with Marvell won’t result in shipping products until 2013, but Wilocity’s VP of Marketing, Mark Grodzinsky, told us that the Marvell/Wilocity chips will focus on a broader range of products including tablets, Ultrabooks, and phones. The two companies are also targeting access points, residential gateways, and media center devices.

From Engadget: Galaxy S III sales breach 10 million, satisfy Samsung executives

Galaxy S III sales breach 10 million, satisfy Samsung executives

Wondering if Samsung’s new flagship has hit its sales goal yet? Breathe out — it did. According to Yonhap, Shin Jong-kyun, head of Samsung’s information technology and mobile communication division, told reporters the firm has moved more than 10 million Samsung Galaxy S IIIs since its unveiling. Jong-kyun wasn’t able to give specific numbers, but we know from history that the handset is outpacing its predecessor, which took five months to make eight digits in sales. As for the goal, Sammy previously pegged the 10 millionth unit for early July, noting that it was fighting component shortages along the way — all in all, mid-month isn’t too far off. Thinking of helping the firm bolster its numbers further? We’ve got a whole series of reviews you may want to take a look at.

From Engadget: UCLA creates transparent solar cell, dreams of current generating windows

UCLA creates transparent solar cell, dreams of current generating windows

Transparent photovoltaics have yet to grace the face of your smartphone, but don’t give up hope — UCLA researchers are working on a new see-through solar cell that’s showing potential. Using a new type of polymer solar cell, the team has been able to build a device that converts infrared light into electrical current. Current prototypes boast 4 percent energy conversion efficiency at 66 percent transparency — not crystal clear, but certainly clean enough to peer through. According to a study in ACS Nano, the technology could be used in “building-integrated photovoltaics or integrated photovoltaic chargers for portable electronics.” Translation? It could one day be used to build solar windows or better sun collecting smartphones. Don’t get too excited though, the technology still has a ways to go before any of these dreams come to fruition. Still, feel free to head past the break for the team’s official press release, or skip to the source to take in the full academic study.

From Popular Science – New Technology, Science News, The Future Now: For the First Time, X-Ray Video Looks Inside Live Working Batteries

Watching Batteries at Work Senior staff scientist Mike Toney and postdoc Johanna Nelson inspect the transmission X-ray microscope at SLAC’s Stanford Synchrotron Radiation Lightsource, a powerful device that takes nano-scale images of chemical reactions in batteries while they are running.

Powerful X-ray images are showing for the first time what happens inside a working battery as it discharges power, and it could lead to improvements for a new type of battery that promises better storage capacity at a lower cost.

Electric cars and other technologies use lithium-ion batteries, which are useful in part because of their high energy density. Cheaper lithium-sulfur batteries could have even higher densities, but they stop working after only a few charge-discharge cycles. Researchers at the SLAC National Accelerator Laboratory are watching them work to determine how they could be improved.

SLAC postdoc Johanna Nelson used X-ray diffraction and transmission X-ray microscopy to capture nanoscale images of the battery’s components, a lithium anode and a sulfur-carbon cathode surrounded by an electrolyte. They captured images of sulfur particles before, during and after battery discharge, and found some unexpected results.

Previous research on these types of batteries showed the sulfur and lithium form certain compounds when they react, trapping the sulfur permanently in new compounds. Formation of these compounds, called polysulfides, can kill a battery in just 10 charge-discharge cycles – not nearly good enough for almost any tech, let alone something like an electric car. But this new research shows it may not be as bad as expected. Very few of these polysulfides actually went into the electrolyte, far less than other research had shown. This means it might not be too difficult to trap them at the cathode, preventing any from leaking into the electrolyte and harming the battery.

“If [scientists] really want to know what’s going on inside the battery, they can’t just use standard analysis. They need a technology that tells the whole story,” Nelson tells Stanford News.

The research appears in the Journal of the American Chemical Society.

From Engadget: Wi-Fi Media lets your Nexus 7 play movies on any screen via HTC’s Media Link HD

WiFi Media lets your Nexus 7 play movies on any screen via HTC's Media Link HD handson video

We’re rather big fans of the Nexus 7 here at Engadget HQ — it’s just hard not to like a $200 tablet with a Tegra 3 SoC and 7-inch glass-bonded IPS display running pure Jelly Bean. Of the few missing features, there’s one we’re bemoaning more than the lack of rear camera, and that’s the absence of any kind of HDMI or MHL video output. So far, watching movies with the Nexus 7’s been relegated to using a Nexus Q and streaming content from Google Play or YouTube.

Enter Wi-Fi Media, an app available for free on Google Play that lets most Android devices like the Nexus 7 play movies, music and stills on any screen via any Cavium PureVu-compatible streamer, such as HTC’s $90 Media Link HD. We tested Wi-Fi Media with our Nexus 7 and Media Link HD and found it to work pretty much as advertised except for some caveats. First the app doesn’t mirror your screen — you’re limited to playing content stored on the tablet or on the network via DLNA, which means no YouTube, Netflix or games. Second, the app doesn’t handle some common file types — like AVI, for example.

While it supports watching movies, listening to music and looking at pictures, keep in mind that Wi-Fi Media is not a particularly polished app. In addition to playing local and remote DLNA content, you’re able to login to Facebook and Picasa and stream images directly from these accounts, but that’s pretty much it in terms of functionality. There’s also no way to configure the Media Link HD, so you’ll need a sanctioned HTC handset to setup the multimedia streamer before using it with a Nexus 7. Want to know more? Peek at our screenshot gallery below and hit the break for our hands-on video.

Update: Since there’s some confusion in the comments, we’d like to clarify that the Media Link HD is not a DLNA device. It normally only works with select HTC phones like the One X, One S and EVO 4G LTE. WiFi-Media’s primary purpose is connect with a Media Link HD — it also just happens to support DLNA.

[Thanks, Matt]
