Overclocking Support Will be Available in Non-K Series Intel Skylake Processors
Information obtained by Chinese site Benchlife has revealed that Intel Skylake processors that aren't part of the K-Series will feature overclocking support. K-Series processors feature better support for overclocking through the ability to change the CPU multiplier and base clock. In the past Intel had restricted support for base clock adjustments to high-end Z-Series motherboards, while disabling the feature on H, Q, and B Series boards. Z-Series motherboards are still expected to provide the best overclocking capability and support on lower end boards "will solely depend on the motherboard maker."

Ouya Software Assets Purchased by Razer
The Ouya was an Android based gaming console that raised $8.6 million on Kickstarter but fizzled out shortly after its release. Razer has now confirmed that it purchased the Ouya software assets for a price reported to be near $10 million. Razer has its own Android based console, the Forge TV, and won't need to continue making Ouya consoles. As part of the purchase Razer has stated that it will help Ouya users make a "clear path of migration to the more advanced Forge TV."

NVIDIA’s Pascal GPU to Feature 17 Billion Transitors
Many hardware manufacturers are hard at work getting ready for 16 nm and 14 nm manufacturing processes, which will allow for much higher densities and increased efficiency. According to Fudzilla, NVIDIA is going to take advantage of the 16 nm FinFET process used to make next year's Pascal GPUs to pack in 17 billion transistors. At 17 billion, it more than doubles the Titan X's transistor count of eight billion and almost doubles the 8.9 billion found in AMD's R9 Fury X.
Fudzilla also reports that by using HBM2, the Pascal GPUs could feature 16 GB or 32 GB of memory, depending on the SKU you are looking at. With up to 256 GB/s bandwidth per HBM stack and four stacks, we are looking at 1 TB/s memory bandwidth for these GPUs. That doubles the maximum bandwidth of AMD's Fiji GPUs, which are using the first generation of HBM.

Pictures and Performance Numbers for R9 Nano Appear
In the quickly approaching month of August, AMD will be launching the R9 Nano, which is rumored to have a full Fiji XT core, like the R9 Fury X GPU, but in a far smaller, 15 cm long package. To achieve this and keep within its 175 W TDP, it will almost certainly feature lower clock speeds, so the question on many people's minds is just how well it will perform. The folks at WCCFtech found at IYD.KR pictures of the card and notes that, after some quick math, indicate the Nano was able to achieve 24.0 FPS in the Unigine Heaven benchmark at 4K, with the Extreme preset and no anti-aliasing. Not too bad for a card that can fit into mini-ITX casing.
Now all we need is it to finally release.

Wireless Power Transfer Efficiency Doubled
Wirelessly charging our devices has been a dream for many for a long time, and now we are starting to see it, but it still needs some work. For the technology to become more practical, its efficiency must be increased, and one means to achieve that is to add intermediate materials between the transmitter and receiver. Metamaterials are one contender for this position, but researchers at North Carolina State University have found an alternative that could be even better.
Wireless power transfer works by generating a magnetic field from one coil and having a receiving coil, in your device, draw energy from that field, some distance away. As magnetic fields go in all directions, the energy they hold can quickly dissipate, so focusing the field can significantly improve efficiency. As metamaterials can interact with various fields in special ways, they make sense to use here, but the researchers found that magnetic resonance field enhancers (MRFEs), as simple as a copper loop, can actually surpass metamaterials. This is thanks to how the MRFEs couple with the magnetic fields, causing less energy to be lost to the material.
When tested against metamaterials, the MRFE was five times more efficient, and fifty times better than when the energy was transferred through the air alone. That is very significant and could do a lot to enable new wireless charging applications beyond phones and tablets, to potentially electric vehicles.

GTX 750 Ti Prices Reduced Ahead of GTX 950 Release
NVIDIA has officially reduced the price of its GeForce GTX 750 Ti graphics cards just weeks before the expected launch of the GTX 950, which is a GM206 graphics card that is simply a reduced version of the GeForce GTX 960. The GTX 750 Ti was previously going on sale for around $150, and the price cuts for the card have brought the for sale price down to $119, making it once again quite competitive. While customers in France and the UK seem to have access to the reduced prices already, United States retailers are slowly implementing the price cuts, which can be seen on a few MSI and Zotac GTX 750 Ti models.
It was hinted that NVIDIA was actively working on the GTX 950 earlier this month, and the card now has itself a launch date of August 17, 2015. The upcoming video card from NVIDIA is expected to feature a core clock speed of 1150 to 1250MHz, a boost clock speed of 1350 to 1450MHz, 2GB of VRAM running at 6.6 to 6.75GHz, and a TDP of just 90W. At the moment, analysts are expecting the GeForce GTX 950 to feature an MSRP as low as $129 and as high as $149 upon launch.

Replacing Injections with Dissolvable Microneedles
Vaccinations save millions of lives every year, which makes it important to make them easier and safer to use. This is easier said than done though, as traditional needle injections come with some risk and can require a level of medical training. As published in Biomaterials, researchers at Osaka University have developed a new vaccination solution that addresses many of these problems, and may even be superior to needle injections.
The basic idea being employed by the MicroHyala method is to use microneedles to apply the vaccine, instead of a single, larger needle. This use of microneedles is not new, but previous efforts have used silicon or metal needles, which can be problematic if they break off in the skin. Instead of these materials, the Osaka researchers are using hyaluronic acid, which is a natural substance found in our joints. Hyaluronic acid dissolves in water, so when the patch is applied like plaster, the microneedles, which have penetrated the top of the skin, will dissolve into the body, bringing the vaccine along.
The researchers tested their new patch by immunizing people against three kinds of the flu, sing the patch and traditional needle injections. No one had a bad reaction to the patch, and the patch was shown to be as good, or even better than the needle injection method. This work is very important because it could change how vaccines are applied around the world, and make it easier for many vaccinate people in areas with limited medical resources.

Quantum Mechanics Brought Out at Room Temperatures
Since its discovery, quantum mechanics has been a realm largely separate from the classical world we live in. This makes it challenging to study some quantum phenomena, which require ultra-low temperature, just above absolute zero. One example of this is Bose-Einstein condensates, but researchers at Polytechnique Montréal and Imperial College London have successfully created a polariton condensate at room temperature.
Polaritons are a quasiparticle formed from the coupling of light and matter and condensates are created when a large number of bosons are all given the same quantum state. To create the polariton condensate, the researchers placed a 100 nm thick film of organic molecules between two mirrors and fired a laser at it. The researchers then observed the blue light that was emitted to study it. Not only was this accomplished at room temperatures, but its scale was also near that of a human hair, which is far larger than most quantum systems.
This work could lead to a number of things, including advanced technologies like polariton lasers and transistors that operate on light. It is also significant because of the use of organic molecules, instead of the ultra-pure, inorganic crystals typically required for this work.

Windows 10 Works Just Fine on Acer Aspire One from 2008
Microsoft has boasted that its next iteration of the Windows operating system is supposed to work on all devices that previously ran Windows 7, Windows 8, and Windows 8.1. In order to test this claim, Bogdan Popa at Softpedia decided to install Windows 10 on an Acer Aspire One that was released seven years ago, in 2008. The Acer Aspire One features an Intel Atom N450 processor running at a smooth 1.66GHz, 1GB of RAM, and a 320GB hard disk. The installation of Windows 10 was facilitated through a USB drive, and only took 15 minutes to fully install, with the user account setup taking just a few minutes more to get everything up and running. All drivers for the Acer Aspire One were installed without user interaction, the maximum screen resolution was automatically set, and the performance of the mobile device was flawless when navigating through various menus.
Although the device of course performs poorly when running demanding applications, and Windows 10 takes roughly 40 seconds to boot from a cold start, it is relieving that Microsoft is fully committed to supporting older systems.

Bethesda Announces the Fallout Anthology for PC
QuakeCon kicked off today, and during the opening ceremony, Bethesda's Pete Hines started it off with a blast: Fallout Anthology. For the first time, gamers can pick up a collection containing Fallout, Fallout 2, Fallout Tactics, Fallout 3: Game of the Year Edition, and Fallout: New Vegas: Ultimate Edition in one handy package. And since this is the Fallout universe we're talking about, Bethesda is packaging the whole thing in a collectible Fat Man mini-nuke container, complete with bomb sounds. All five Fallout games included in the Anthology feature a sweet collectible case with custom artwork from each game on it, and there is even room inside the mini-nuke for your copy of Fallout 4 (well, if you didn't get a digital copy). There's no word if GFWL has been removed from Fallout 3 (I would have to imagine it is) or if everything is optimized for Windows 7 and beyond, but I would have to say Bethesda took care of that.
The Fallout Anthology arrives only for PC on September 29 in North America and October 2 in Europe. It will set you back $50, with pre-orders now live.

Friction Removed on the Macroscale for the First Time
For many systems, friction is an enemy as it takes away energy that could otherwise be used, or wears down components. Ways to reduce and remove friction are naturally very important then, with the ultimate goal being superlubricity. When superlubricity is achieved, friction seems to vanish, and now researchers at Argonne National Laboratory have discovered a way to bring it to the macroscale.
Like many discoveries, this one was made almost by accident when the researchers were studying a new lubricant material comprised of graphene and diamond-like carbon (DLC). When the material was modelled on a supercomputer, the results indicated the graphene was rolling up into hollow cylinders, or scrolls. These scrolls are what led to the superlubricity by separating the surfaces involved. Prior to the modelling, testing the lubricant demonstrated the friction would fluctuate, which the model explained. When the scrolls formed, friction would practically vanish, but they would then collapse due to the pressure on them, causing the friction to return. The researchers were able to solve this problem by adding nanodiamond particles, which the scrolls formed around and made them more permanent, thereby extending the superlubricity.
This discovery could have many significant applications from turbines to hard drives, which is why the research team is already working to patent the hybrid material. There is still one issue to overcome though, and that is that water and humidity impairs the formation of the scrolls, thus limiting where the new lubricant can be used. With further research and computer modelling though, the researchers will hopefully find a solution.

Semiconductor Junctions Created Within 2D Materials
The future of electronics will likely be thin, but not in the sense that it will fit better in your pocket. Instead there is a push to use two-dimensional crystals for building devices, instead of the current 3D crystals used. Now researchers at ORNL have devised a novel way to form arrays of arbitrary patterns within a 2D semiconductor crystal.
The researchers started with a single, nanometer-thick layer of molybdenum diselenide that then had silicon oxide applied to create the protective pattern. Next a beam of sulfur atoms was shot at the material. The sulfur atoms knock out and replace the selenium atoms wherever they strike, resulting in two semiconductor crystals separated by sharp junctions. Because the sulfur atoms were applied using pulsed laser deposition, it is possible to precisely control the ratio of selenium to sulfur, which influences the bandgap of the resulting hybrid material.
The next step for the researchers is to determine if this method can work on materials other than sulfur and selenium. This is very important as electronics require semiconductors, insulators, and metals.
