The First-Ever Images of Atoms Moving Inside a Molecule [Science]

Source: http://gizmodo.com/5891519/the-first+ever-images-of-atoms-moving-inside-a-molecule

The First-Ever Images of Atoms Moving Inside a MoleculeOhio State University researchers have captured the first-ever images of atoms moving within a molecule using a novel technique that turns one of the molecules own electrons into a kind of flash bulb. The technique has yielded a new way of imaging molecules, but could one day help scientists to intimately control chemical reactions at the atomic scale.

The images were snapped using an ultrafast laser, which fired 50 femtosecond (a femtosecond is a quadrillionth of a second) pulses at the molecule to knock a single electron outside of the molecules outer shell. This electron, having been knocked out of its proper place, comes crashing back into the molecule, and in doing so it provides the kind of illumination the researchers need to image the molecule itself.

By measuring the scattered signal of the electron as it collides with the molecule, they were able to reconstruct the inner workings of the molecule, including things like the positions of the atoms nuclei. Moreover, because there is a very short lag between when the electron is knocked out and when it comes crashing back, the researchers are able to capture the movement of the atoms within that period, essentially allowing them to make a frame-by-frame film of atomic motion within molecules.

For their experiments the researchers used oxygen (O2) and nitrogen (N2) molecules because their molecular structures are well understood. The next steps will involve imaging more complex molecules and, eventually, figuring out the potential for precisely controlling chemical reactions right down to the atomic level.

Apple TV software update brings new interface to second-gen models

Source: http://www.engadget.com/2012/03/07/apple-tv-software-update-brings-new-interface-to-second-gen-mode/

In what will surely be welcome news for many, it turns out you don't have to drop another $100 to get everything the new Apple TV offers. Owners of the second generation model can now download a software update (version 5.0) that adds the same interface found on Apple's latest device, along with support for other new additions like the ability to pay for Netflix through your iTunes account. No magic upgrade to 1080p, though. Check out the gallery below for a closer look at the changes.

New iPad: The Third Generation (Updating Live) [Ipad Hd]

Source: http://gizmodo.com/5891158/new-ipad-hd-the-third-generation

New iPad: The Third Generation (Updating Live)The new iPad is here. Apple's new tablet computer has arrived and its ultra-sharp 2048 x 1536 pixel Retina display is enough to set it apart from anyone else. It's almost like looking at a glossy magazine page.

It also has much more powerful guts, with a much faster processor, graphics and more memory. And it's 4G ready.

Retina display

The Retina display looks gorgeous. The screen has a 264 pixels per inch. That's a total 3.1 million pixels in a full color IPS screen. The image color seems a lot better too. They say it has 44 percent more saturation than the IPS technology they were using previously.

Apple claims that it is still a Retina display because, when you held it at a normal distance, you just can't see the pixels. That distance is 15 inches. For the iPhone, which has a smaller screen, it is 10 inches. I can't wait to test this thing with all my comics (I wonder if Marvel will have to upload them all again).

They demonstrated it running a new version of Autodesk Sketchbook Ink, a new painting app that is vector-based and resolution independent. It actually seems like you are painting on a real page.

New iPad: The Third Generation (Updating Live)

Processor and graphics power

The processor is an A5X, which includes a quad-core graphics module. It's going to need all the graphics muscle if it has to push those 3.1 million pixels.

According to Apple, it's twice as fast as a Tegra 3 and has "four times" the graphics performance. Hot damn.

New camera

The new iPad has a new camera on the back: has a 5-megapixel job with a side-iluminated sensor, a 5-element lens and an infrared filter. It's basically the same configuration as on the iPhone 4S, with three fewer megapixels. Serious specs for a tablet camera—you can expect to see more people carrying around iPads taking pictures of things. Great.

1080p video recording

The rear camera, which Apple calls the iSight Camera (the front-facing one is the facetime camera), is capable of capturing 1080p video, which obviously looks razor sharp on the iPad's display. The video, like the iPhone 4S, is also stabilized.

Apple says it has temporal noise reduction, which is a rather clever technique that greatly reduces the noise of video by comparing what pixels actually move and guessing what is noise and what is actual detail.

New iPad: The Third Generation (Updating Live)

Dictation

The new iPad's operating system offers a new microphone button, which will allow you to dictate emails, presumably using technology related to Siri technology. There was no actual mention of Siri assitance.

4G LTE connectivity

Apple says the new 4G LTE connectivity will give you 21Mbps on HSPA+ networks, 42Mbps on DC-HSDPA and 73Mbps on LTE. Of course, these speeds are theoretical. It will run on both AT&T and Verizon networks. According to Phil Schiller, the new model "has the most wireless bands that has ever shipped."

Memory and other guts

Apple is not mentioning actual specifications for the guts of the machine, but it's pretty clear that the memory—not the storage, but RAM used for running the OS and the applications—has increased too, if only to handle the new resolution.

Mike Capps, from Epic Games, says that it has more memory than an Xbox 360 or a PlayStation 3. Presumably, his comment refers to graphics memory. We will know soon how much this is exactly.

Physical specifications

Surprisingly, they have kept the package practically just the same as the previous version: only 0.03 inches thicker than the iPad 2 at 0.37 inches (9.4 millimeters). The weight is only 1.5 pounds.

Launch date

You will be able to get it on March 16, but the preorder starts today. It will be available in the US, Canada, United Kingdom, France, Germany, Switzerland, Japan, Hong Kong, Singapore and Australia on the same day.

The price is $499, $599 and $699 for 16, 32, and 64GB. If you want 4G LTE, you will have to spend $629, $729, and $829.

One more thing

The name. Did you notice it? The name is not iPad HD. It just iPad. Which demonstrates two things.

First, that rumors are bullshit (but I always tell you that. All the rumors are when it comes to Apple. They just become true if you give them enough time).

Then, and most importantly, it shows that Apple has finally realized that this naming scheme was going nowhere. Does iPad 15 make any sense to you? No. Which is why they have just adopted the same strategy as they adopted with MacBooks and iMacs. Just call them by their name and attach a year number or some other descriptive string in your stock systems. It makes sense.

So much sense that I bet they will call the iPhone 5 just the iPhone. You heard that rumor here first, folks! BELIEVE IT!

Intel Ivy Bridge touchscreen Ultrabook reference design hands-on (video)

Source: http://www.engadget.com/2012/03/07/intel-ivy-bridge-touchscreen-ultrabook-hands-on/

Interested in replacing both your tablet and that clunky notebook with a svelte all-in-one portable? Intel might have just the gadget for you -- an Ivy Bridge Ultrabook with a built-in 13.3-inch 1600 x 900-pixel capacitive-touch LCD. We happened upon such a device in the bowels of Intel's gaming-centric CeBIT booth, and had a chance to go hands-on with the company's one and only (at this show, at least) reference design touchscreen Ultrabook. The device we saw appeared to be no larger or thicker than similar portables, but integrated a gorgeous 13.3-inch touchscreen, along with that elusive 1.5GHz Ivy Bridge processor. Unfortunately Intel was mum on detailed specs, though the prototype we saw did include a pair of USB 3.0 ports, SIM and SD card slots, and an HDMI port. And according to the system info page, the touch feature supports up to 10 individual input points. We're also told that there might be NFC functionality on-board, though the only visible confirmation of this hardware feature was a piece of medical tape with the letters "NFC" inscribed.

The touch functionality worked just as expected -- if you've used touch on a high-end tablet before, you're already familiar with the experience here. We were able to navigate the installed Zinio app with ease, flicking through magazine pages and pinch-and-zooming our way around a cover. You can of course use the touchscreen to adjust system settings, drag-and-drop files or input text with the on-screen keyboard, though we found the trackpad and ! hardware keyboard to be more practical here. Overall, this appears to be a no-compromise solution -- it will surely add to the manufacturing cost for next-gen Ultrabooks, but if you opt for a touch-equipped model only to find that you prefer traditional input controls, there's not much lost on the feature front. And, if you do happen to enjoy flicking your way around a notebook, you're definitely in for a treat. You'll find our hands-on video just past the break.

Ivy Bridge benchmarks: CPU boosted 5-15 percent, onboard GPU handles Skyrim

Source: http://www.engadget.com/2012/03/07/fresh-ivy-bridge-benchmarks/

We've heard whispers of Ivy Bridge's benchmarking prowess, but now we have more comprehensive and independent test results of a Core i7 3770K CPU, courtesy of AnandTech. The conclusion? The upgrade is "quite good," which is Anand Lal Shimpi's way of describing a 5-15 percent boost in CPU performance for the same money as Sandy Bridge, not to mention lower power consumption and the ability to run the latest games on the HD 4000 integrated graphics. Of course, this latter discovery requires clarification: some games, such as Metro 2033 could only achieve 30fps at a max resolution of 1366 x 768, but others fared better. Crysis Warhead ran at 50fps even at 1680 x 1050. With that type of onboard oomph, you'd have to spend over $100 on a discrete graphics card for it to be worthwhile, which even Lal Shimpi acknowledges is "sort of insane". Check out the source link for more.
