For most of us, molecular bonding only really exists as a classroom concept. Some scientists at Lawrence Berkeley National Laboratory can now claim more tangible knowledge, however: they’re the first to have taken truly clear snapshots of bonding in progress. While trying to create graphene nanostructures and observe them with an atomic force microscope, a lab team spotted molecules forming their individual, atom-level links during a chemical reaction. The resulting shots were nearly textbook material, too — as the molecules were neatly placed on a flat surface, the researchers identified the order and nature of each bond. While the images will only be immediately useful for the nanostructure research at hand, they may add a welcome dash of reality to future chemistry lessons.

Ultra HD may be gaining momentum, but we’re still not used to seeing it packaged so neatly for the desktop as in the new ASUS PQ321 display. Offering 3840 x 2160 resolution spread across 31.5-inches, the new “True 4K” Monitor not only delivers four-times the pixels as regular Full HD, but does so using an IGZO panel that promises improved brightness and detail while sipping less power and coming in thinner than any other Ultra HD display.
IGZO panels use Indium Gallium Zinc Oxide, rather than amorphous silicon. Since that supports greater electron mobility – roughly 40x the amount, in fact – the pixels can be smaller than on traditional LCD panels.
ASUS doesn’t detail exactly where it’s getting the IGZO screen from, but the most obvious source is Sharp. The Japanese company announced back in April 2012 that it was entering bulk production of a 32-inch IGZO panel running at the same resolution as ASUS’ PQ321.
We’ve already seen IGZO prove its worth on smaller panels in the wide. A number of smartphones and tablets have been released for the Japanese market using Sharp’s screen technology; we spent some time with the Sharp AQUOS Tab SHT21, for instance, which promises a choice of either matching brightness from rival devices but with roughly double the battery life, or of boosting brightness to levels where the tablet can be easily used outside.
According to ASUS’ specs, the PQ321 delivers 140ppi and 350cd/m2 brightness, with an 8ms gray-to-gray response time. Viewing angles are 176-degrees in both directions, while inputs include DisplayPort, two HDMI, serial, and audio in/out. 2W stereo speakers are also fitted, and there’s picture-in-picture support.
The whole thing is 35mm at its thickest point (the stand adds to that, obviously), though you’ll still need a reasonably sized desk in order to accommodate a 31.5-inch display. A deep wallet is probably required, too; ASUS hasn’t announced pricing for the PQ321, but Sharp’s own 32-inch Ultra HD monitor carried a whopping $5,500 tag when the company announced it back in November.

Samsung‘s upcoming Galaxy Tab 3 10.1 will use an Atom processor rather than an ARM-based chip, multiple sources claim, marking a high-profile win for Intel and a perhaps surprising move for Samsung, which makes its own Exynos ARM silicon. The new 10.1-inch Android tablet will use a Clover Trail+ processor in at least one of its variants, both Reuters and Korea Times report, with insiders at Samsung and Intel supposedly confirming rumors about the architecture switch that had been circulating for the past weeks.
Although Samsung has already scheduled a standalone event in the UK on June 20, at which the company has promised the reveal of new Galaxy and ATIV hardware, the Galaxy Tab 3 10.1 apparently won’t wait that long to break cover. In fact, Samsung is tipped to be unveiling it at Computex, which kicks off on June 4.
Other specifications for the tablet are unclear, though it’s likely to use an LCD display rather than Samsung’s AMOLED panels, based on previous models of the same size.
Initially, speculation that Samsung would look to Intel’s chips was met with some degree of skepticism, not least because Samsung has its own chip production facility. The company’s Exynos processors have already been used in numerous Samsung products, leading to questions as to why the brand might dilute its “home supplier” advantage.
According to the Korea Times, however, the deal with Intel is part of Samsung’s strategy to hedge its bets on chip supply. “Samsung wants to secure as many processors as possible at better pricing” an unnamed member of Samsung’s research team told the Korean source. “That’s why Samsung Electronics has recently been diversifying its procurement channel in processor chips as a strategy to stabilize production yields of its in-house Exynos-branded processors.”
Intel, for its part, has apparently been more than willing to accommodate Samsung casting a broader net for its processor supplies. The x86 company has supposedly offered highly competitive prices for the Atom CPUs, and has reportedly increased its Atom chip specialists based at Intel Korea eightfold, to more than 50, in the space of a year.
“Most of them are working for Samsung-related projects with a mission to customize circuits for adaptation on Samsung products” an unnamed Intel source suggested.
Intel has had some quiet successes with its Android-on-x86 push, including the Motorola RAZR i launched last year, which impressed with its performance even if sales didn’t quite compete with other high-profile handsets. The company has previously confirmed its goal to take a bigger bite of the mobility pie, aiming to undermine ARM’s success in the smartphone and tablet industry, though difficulties achieving the same degree of power efficiency and performance have undermined Atom chips.

The White House Press Corps homepage and Twitter feed appears to have been hacked early Friday.
Just before 2 a.m., tweets began flowing into @whpresscorps, complaining about bias in the media. The hackers’ beef seemed to be with any news organization that met with Attorney General Eric Holder to discuss how the Justice Department will handle future instances of spying on journalists.
Numerous news outlets refused to attend the meeting with Holder because it was supposed to be “off the record.” But five chose to go, and those were the ones lambasted by the unknown hacker(s):
