While Microsoft has yet to release Windows 10 to manufacturers, the company is already working on what will be known as Windows 10.1. The recently unveiled version of the Windows operating system, which is codenamed Redstone, is expected to be similar to what Windows 8.1 was to Windows 8. Features that get cut from the RTM version of Windows 10 will likely be featured within Redstone, which is expected to roll out to Windows Insiders before it makes its way to the general public in two phases. The first phase is scheduled to begin in June 2016, while the second phase is expected to take place in October 2016, although the time frames could change due to Redstone being over a year away and included features and bug fixes being unknown at this time.

Gyroscopes are used in a variety of places for measuring movement, and without them many vehicles, like rockets and satellites, would not be able to guide their flights as necessary. Especially in those two examples, it is very important to keep size and weight down to a minimum, but accuracy also cannot be sacrificed. As published in The Optical Society's journal Optica, researchers have developed a new optical gyroscope that is the world's smallest, at just microns across.

Optical gyroscopes are not a new technology and operate very differently from the classic gyroscopes we have probably all encountered in school. Where those gyroscopes rely on Newton's laws, optical gyroscopes use the Sagnac effect, which describes a color shift when light splits and recombines as it exits a spinning system. The problem has been that both of the two basic designs, using either an optical cavity of optical fiber, have degraded performance as they are made smaller, so as much as six kilometers of optical fiber may be used. The researchers got around that though by changing what they were looking for. Instead of trying to sense a change in color, they instead watched for the small, but still measurable relativistic effect of rotating a light source bending spacetime. The resulting distortion can then be analyzed to determine the speed the cavity was rotating at.

By bringing the size down to potentially just 10 microns across, this new optical gyroscope design could be fit into a number of technologies, and integrated into optical circuit boards. More work needs to be done though, to take different optical modes into consideration and to enable measurements of full 3D movement.

Multiple sources have told Kotaku that the previously reported licensing deal made by Crytek that bailed it out of financial troubles was with Amazon. When the deal was announced Crytek co-founder Faruk Yerli stated "It was a huge one, probably the biggest one. I can’t say anything more in detail, but hopefully we’ll be able to announce it with the partner soon." The deal was reported to be worth between $50 and $70 million though it remains unknown what Amazon plans to do with the license. Amazon has made a number of previous moves in the gaming world including hiring top developers from Portal and Far Cry 2, purchasing studio Double Helix, and launching the Fire TV and this move could indicate that Amazon "has grander ambitions for gaming."

NVIDIA currently finds itself in a patent lawsuit with Samsung and Qualcomm regarding its GPUs filed with the United States International Trade Commission and US District Court in Delaware. The trial is set to take place in June, but a recently held Markman hearing has given NVIDIA favorable rulings on six of seven definitions. The purpose of a Markman hearing is "to make sure the actual trial is done on the basis of merit and facts – not needless arguing over legal definitions and context." NVIDIA Chief Administration Officer and Secretary David Shannon addressed the outcome stating, "We are very pleased with the outcome of the ruling, in which claim constructions favorable to Nvidia will be applied to six out of seven disputed claims when the judge considers the question of Samsung’s and Qualcomm’s infringement. This further strengthens the patents we have asserted, and we look forward to a full hearing in late June."

A new day is here, and if you're looking for a new CPU cooler, you're in luck as today we have both air and liquid models up for review. On the air cooling side there's the Scythe Ashura SCASR-1000, which is a tower-style cooler with a 140mm fan and a 162mm height. For the liquid coolers, we have a roundup of the Asetek 510LC, 550LC, 570LX and 591LX, which are all used in pre-built rigs from CyberPowerPC and iBUYPOWER, or even rebranded by other companies. All four make use of 120mm fans, but while the first two are just a single 120mm radiator, the 570LX is a double radiator, and the 591LX a triple to fit up to six fans in a push/pull setup.

Battery technology is a big deal as so much of our life uses devices that rely on them, in one form or another. While we may rely on them, there are some aspects to these batteries we dislike, such as slow charging speeds and potential safety hazards. Researchers at Stanford University may have developed a solution though by creating a rechargeable aluminum battery.

Aluminum is actually the most common metal on Earth, so it is very cheap, and because it has great potential for storing electrical charge, many have tried to make a battery with it before. One of the challenges preventing these batteries from existing has been the search for materials to produce a useful voltage from such a battery. The Stanford researchers were lucky in that regard as they accidentally found that a simple solution of graphite could act as a very effect cathode. They then built a prototype battery consisting of an aluminum anode, graphite cathode, and liquid electrolyte, all inside a flexible polymer-coated pouch. This design has many useful properties to it, including the electrolyte being liquid at room temperature and the components not being flammable, unlike lithium ion batteries. In fact the researchers drilled a hole through the battery, and it still functioned, and were also able to bend and fold it, while it worked. Besides these mechanical properties, the prototype battery can also be charged in just a minute and survive 7500 cycles before losing capacity. Lithium-ion batteries tend to last about 1000 cycles, for comparison, and previous aluminum batteries only survived about for 100.

While there are definitely more than enough properties to warrant further research into this technology, it does still have one significant flaw. The aluminum battery can match and exceed the voltage of AA and AAA batteries, but comes to only half that of a lithium-ion batteries. The researchers believe that improving the cathode can raise the voltage and energy density enough to compete with modern batteries.

Gamers have been clamoring for a PC release of Rockstar's Red Dead Redemption, which is something that probably won't happen. However, there may be hope for a sequel, and we could have something solid on that soon. Now, take everything that follows with a heavy dose of salt, but a Redditor by the name of AnonDN1978, supposedly a former Rockstar developer, claims to have information on Red Dead Redemption 2. The game is known as Red Dead Redemption 2: Legends of the West, and is a prequel to the events of Red Dead Redemption. RDR2 is set in the same area as RDR1, but 12 years before (so 1899).

Like Grand Theft Auto V, RDR2 will have three main characters, with two returning from the previous title. Those two characters, Seth and Irish, are who players will be able to control during single player, with the third character as a "gun for hire" working with them. More stranger missions appear in RDR2, along with roughly 30 campaign missions. The third character is apparently a user-created one, with appearance, clothing, and horse all customized by the player.

The two "main" characters are Irish and Seth. Irish will be brought up in Ireland and will move to the Americas when he is fifteen and moves to the game setting when he turns twenty one. Seth is from Kansas City and works as a teller in a bank. He then hears of a treasure and uses his life savings to bring his family to Texas in the town of Tumbleweed. Throughout the story we experience him unraveling to his state of mind in the original game, losing his wife, children, home, and possessions to his treasure.

The third person is a character you create similar to multiplayer in GTA V. You choose his clothes and horse. Although you can unlock outfits for Seth and Irish, the third person (Who you name) can acquire all different kinds of Western tops, bottoms, boots, gloves, and hats.

It sounds like an interesting experience, and especially more so when AnonDN1978 says horses can have different saddles to boost various stats, purchasable and customizable safe houses, and the fact that all of this carries over into a multiplayer mode. Multiplayer is centered on the created character, with Seth and Irish as computer-controlled companions. Many of the characters met in RDR1, even protagonist John Marston, will appear in multiplayer.

A gang system plays a central role in RDR2, with players able to join different gangs through the game. If you're feeling up to it, you can even join the side of good, although this restricts aspects like robbing, naturally. Robbing is a dangerous thing to pull off in the gang, as it may even cost you your life, but it could have some sweet rewards. A posse between four and eight players can even be brought into the single player mode and turn it into co-op, with some side and campaign missions able to be completed that way.

Red Dead Redemption 2: Legends of the West is supposedly slated to arrive on PC, PlayStation 4, and Xbox One, with Rockstar planning to reveal it at E3 this year. Rockstar typically does not announce games at E3, so like with everything else stated, take it with some salt. It sounds exceptionally promising and enjoyable, but until we have some confirmation one way or the other, this remains an enticing rumor.

AMD claims that its Graphics Core Next based GPUs improve DirectX 12 performance by up to 46% by leveraging the Asynchronous Compute Engines (ACE) built into the architecture. The ACE units take advantage of the thousands of stream processors found on the GPU through the use of Asynchronous Shaders. Proper multi-threading support wasn't available in DirectX 11 as the amount of complexity involved was high and the necessary hardware was unavailable. The use of Asynchronous Shaders "allows for tasks to be simultaneously processed independently of one another." In order to take full advantage of the Shaders, the GPU must be designed with the support in mind, and the ACE units on AMD GPUs fulfill this purpose. In a LiquidVR demo with post-processing enabled, 158 FPS were obtained with Shaders disabled and 230 FPS when enabled, an increase of 46%.

Last July Microsoft announced that it would be laying off 18,000 employees in its "largest ever layoff," which has now been completed. The company informed the remainder of the effected employees last week, with the majority of cuts in the information technology group. CEO Satya Nadella said the cuts were part of an effort to "streamline the company and integrate its newly purchased phone-hardware business."

With the price of 3D printers coming down, and their capabilities constantly increasing, many believe the time will come when many homes have one. Once in the home, they could be put to use building objects found online and possibly duplicating items around the home. In order to duplicate an object though, an accurate 3D image will have to be made, which has become easier thanks to researchers at Caltech.

Technologies for creating 3D images have existed for decades, but typically require bulky and expensive equipment. What the Caltech researchers have created, however, is just a square millimeter in size, yet still capable of micron resolution. It is known as a nanophotonic coherent imager (NCI) and uses LIDAR to capture 3D information with each pixel. It works by sending out a beam of laser light, which is coherent, and then recording the phase and frequency of the light when it returns. Those properties will shift compared to the original beam, depending on the distance the target object is from the sensor.

By shrinking all of the necessary components onto a silicon chip, the researchers were able to fit 16 of these imagers into an array just 300 microns by 300 microns. While 16 pixels is pretty low, it could be scaled up to hundreds of thousands, and because the imager will still be so small and inexpensive, it could lead to many new uses for the technology.

One of the year's biggest RPGs has yet to arrive, with CD Projekt's The Witcher 3: Wild Hunt scheduled to launch on May 19. If you're eagerly looking forward to continuing Geralt's adventure, we may have a way to help hold you over. IGN recently did a playthrough and have showcased the first 15 minutes of The Witcher 3, and boy, is it looking good. Granted, the game is being played on an Xbox One so it is only running at 1600x900 and not 1920x1080, so the PC and even PS4 versions will look that much better. The exact build date for the playthrough isn't known either, but at any rate, things are looking good for the game. Geralt's hair looks glorious as it flows in the breeze, the backgrounds are mesmerizing, and the dialogue sections feature expressive faces and smooth transistions. Oh, and before you're worried, the video below does not contain the opening cinematic, which is perhaps the most spoiler-filled section, so it is good to have that excluded.

The Witcher 3: Wild Hunt arrives on May 19 for the PC, PS4, and XBO. If you want to know just what kind of a PC you need to make Geralt look his best, the specifications were released a little while ago. Plus there's still time to pre-order and save a bit of cash if you own either or both previous games from GOG. You can also get a new GeForce video card and get the game included for free.

It is nearly time to text your might in Mortal Kombat X, and to get your blood pumping we have the launch trailer. System of a Down's Shavo Odadjian directed the trailer and sets it to the band's iconic "Chop Suey!" song, which has plenty of moments that line up perfectly with the game action. A huge cast of fighters appear in the trailer, with everyone from the familiar to the brand new showcased. The fights themselves look to be action-packed, and the story mode seems rather intriguing as we get glimpses of it. Raiden shows off his lighting attacks, Scorpion and Sub-Zero are once more locked in a duel, Liu Kang seems to be sporting some spiffy new armor, Reptile is on the prowl, and several characters appear to have some kind of afflicition that makes their skin distort and open up glowing cracks. It all looks quite promising.

Mortal Kombat X arrives on April 14 for PC, PlayStation 4, Xbox One, Android, and iOS, with the PS3 and 360 getting it on June 2. There's still time to pre-order and get heavy hitter Goro.

According to United States District Judge Yvonne Gonzales Rogers, AMD must now defend itself against plaintiffs who have successfully supported their claims in a lawsuit against the company. Last year, AMD was accused of inflating the company’s share price by making false statements about Llano, with officials noting that there we no problems with supply even though Llano was only shipping to specific computer manufacturers due to supply constraints. By the time supply was where it was supposed to be, demand for Llano was drastically reduced, and as such, the company wrote down that $100 million of Llano inventory was not salable. The case seeks damages on behalf of the Arkansas Teacher Retirement System, KBC Asset Management, and other investors who purchased AMD shares between April 2011 and October 2012.

There are many quantum mechanics phenomena that people wish to exploit for future computing and communication technologies, but the equipment needed to produce them can be an issue. One of these phenomena is quantum teleportation, and in 2013 researchers were able to realize perfect teleportation using equipment that covered several square meters. Now researchers at the Universities of Bristol, Tokyo, Southampton and NTT Device Technology Laboratories have recreated that perfect teleportation in a device just millimeters in size.

Quantum teleportation could be used to transfer the quantum information in qubits across distances, and is thus necessary for connecting quantum computers on a network, or for building a communication network secured by quantum mechanics. In either case, multiple tables full of optical equipment is too much. By using state-of-the-art nano-fabrication techniques, the researchers were able to build a complete teleportation system onto a silicon chip, which has never been achieved before.

The importance of this research is obvious as it represents a significant step toward practical quantum technologies.

Facebook is finding itself in a little bit of hot water, as a report from two Belgian universities alleges the social networking website can track online activity even if you do not have a Facebook account. The report comes from the Belgian Privacy Commission, which tasked the University of Leuven and Vrije Universiteit Brussel to research Facebook's new privacy policies that were updated in January. In the report, Facebook uses cookies to track people's online activities without their consent, regardless of being logged out of Facebook, having a deactivated account, or specifically opted out of online advertising. Apparently it centers around Facebook's "Like" button, which can be found on more than 13 million websites. Cookies can be placed when anyone visits any site on the facebook.com domain, even if you're not logged in or use Facebook. All of this points to a potential violation of European privacy law, which explicitly states that cookies cannot be used without giving consent and that websites must advertise their cookie usage.

A spokeperson for Facebook denied the claims, as the Belgian report contained "factual inaccuracies" and its authors did not contact anyone at Facebook. The inaccuracies were not specified, so right now it is anyone's guess as to what may be incorrect. The spokeperson also said Facebook is in compliance with European privacy law, although the report says otherwise. For right now, it may be best to just keep watch of the cookies and what all information you share, regardless of being on Facebook or not.

Yesterday came the news that ASUS was releasing a GeForce GTX 980 20th Anniversary Gold Edition video card. It is a high-end card with a custom cooler and a huge factory overclock, but that isn't the only thing ASUS is working on. The company also has the GeForce GTX 970 Turbo video card, which has a 1008MHz core clock and a 1228MHz boost clock. The revised stats on the GM204 core features 1664 CUDA cores, 112 texturing units, 56 raster units, and 4GB of GDDR5 on a 256-bit interface, with that VRAM split into two sections just like all the other GTX 970s. However, this GTX 970 Turbo makes use of a mini PCB and a white cooling shroud for an altogether unique appearance. The cooler has some red on it echo the company's ROG line, and is a blower-style cooler to help push the heat out of the case. The rear I/O is not the standard affair on a GTX 970, as ASUS has equipped the Turbo with dual DVI ports, one HDMI port, and one DisplayPort. Up top are two SLI connectors for some Quad-SLI action, and both 6-pin and 8-pin PCIe power connections to drive the card.

Like the GTX 980 20th Anniversary Gold Edition, ASUS did not reveal a price or release date for the GTX 970 Turbo.

One day the electricity coming to our or our descendants' homes may be carried by superconducting cables that transmit electrical currents without resistance. This has been a dream of many for a long time, and continually we are working to achieve it. There are many avenues to this work and researchers at LANL have been focusing on understanding how electrons act in high temperature superconductors.

The theory explaining how low temperature superconductors work was put together in 1957, and while it works well for those materials, it does not explain high temperature superconductors, like yttrium barium copper oxide. Besides the higher critical temperature to set them apart, these materials can also have the temperature they superconduct at changed by doping them. To understand how this works, and if it is related to a quantum critical point, the LANL researchers used a range of dopings and exposed the superconductors to high magnetic fields in excess of 90 Tesla. The magnetic fields had the effect of suppressing the superconductivity, so that the electrons could be observed before superconducting.

The results of the study indicate that the quantum critical point, which is the doping value where electron interactions are strengthened by quantum fluctuations, does in fact drive the transition temperatures of these superconductors. This has been a question for some time, and once finally solved could explain how the electrons pair up to become superconducting, in high temperature superconductors.

Intel recently did a fairly quiet launch of several new processors, with some Braswell SoCs and Broadwell CPUs rolling out. The Braswell SoCs have either one or two CPU modules, with two Airmont cores per module. They also use the 14nm manufacturing process and have some fairly low TDPs that would be a replacement for a Bay Trail-M or Bay Trail-D SoC. The Celeron N3000 and N3050 are both dual-core models with 1MB of L2 cache, with the N3000 featuring a 1.04GHz to 2.08GHz speed and a 4W TDP, while the N3050 has a 1.6GHz to 2.16GHz speed and a 6W TDP. The Celeron N3150 and Pentium N3700 are both quad-core SoCs with 2MB L2 cache and a 6W TDP, with the N3150 running between 1.6 and 2.08GHz, and the N3700 at 1.6 to 2.4GHz.

On the Broadwell side, all three are mobile CPUs with Hyper Threading support, and could likely appear in Ultrabooks or even tablets. The Pentium 3825U, Core i3 5015U, and Core i3 5020U are all dual-core CPUs with 3MB of L3 cache and a 15W TDP. The Pentium runs at 1.9GHz and has Intel HD Graphics (the exact type wasn't listed), the Core i3 5015U at 2.1GHz with an HD 5500 providing the graphics, and the i3 5020U at 2.2GHz with the HD 5500.

All the SoCs and CPUs range in price between $107 and $281, but as these are most likely for trays of 1,000 units, actual retail prices will be a bit higher. Considering these will undoubtedly appear in pre-built devices, hopefully things aren't too outrageous. Exactly when Intel will have these parts ready for retail is not known, but expect word on that before long.

Sony has announced that it has acquired gaming service OnLive, and has immediately announced plans to shut down the service. OnLive is planning to keep the service running at no charge to subscribers until the end of the month. The company has also announced that refunds will be issued to consumers that purchased the OnLive system or controller after February 1. Unfortunately for users, those "who purchased the company's PlayPass games won't be able to play them after the service shuts down, nor will they be able to use its OnLive game system or controller peripheral on any other platforms."

NVIDIA's new GTX TITAN X video card is one massive beast, as it pairs a GM200 core with 12GB of GDDR5 for some 4K gaming on a single card. Now it looks like a new version may be coming out, as a GTX TITAN X Ultra with a closed-loop liquid cooler has been spotted. NVIDIA typically does not allow for its board partners to modify the TITAN series in any way, but this model is apparently done by the company itself. The TITAN X Ultra, if it keeps that name, has the liquid cooler keeping the GM200 core cool, while air cooling handles the VRAM. That liquid cooler apparently allows for a 250MHz overclock to the core, which already comes in at 1000MHz stock. The Boost clock would then jump to the 1325 to 1375MHz range and would be downright impressive.

This is, of course, simply a rumor, but with AMD's flagship card potentially being a dual GPU monster, NVIDIA may just want to have an ace up its sleeve.

It may not be as impressive as the 60 FPS trailer released yesterday but a new Grand Theft Auto V TV spot is out now. The focus of the video is on the Heists for Grand Theft Auto Online, and not on any specific version of the game, but it was shot entirely in the PC version. Heists and all the other Rockstar-created GTA Online content released since it first went live will be included with the release on April 14.

Error is a problem all computers have to deal with, and if we want to see new kinds of computing technologies in the future, the sources of error must be removed or mitigated. This is especially true for quantum computers, which are especially sensitive to error, by the nature of quantum mechanics. As reported by Springer, researchers at the University of Basel and Harvard University have learned how some error-inducing factors come to be in a potential logic gate.

One of the possible ways to avoid errors is to build networks of nanowires in a braid-like pattern, because the tight pattern helps keep them stable. The catch is that local defects can still exist on the nanowires. To gain an understanding of these defects, the researchers build a 2D network of nanowires that quasi particles would move along in a braided pattern. In this situation, the spin of the electrons involved interact with their own movement, creating a spin-orbit interaction, but because the direction of this interaction is not uniform in the network, the local defects arose.

Through their analysis the researchers found that the nanowires where the spin-orbit interaction changed contained Fermionic Bound States. These are what cause the qubits to destabilize and become a source of error. With this knowledge of the bound states' characteristics though, it may be possible to found ways to avoid their effects.

Two years ago during CES, NVIDIA showed off its Project Shield device that married a controller with an Android gaming device. Six months later it arrived, and in the intervening months NVIDIA has launched the SHIELD Tablet, Wireless Controller, and Android Gaming Console. The original SHIELD was renamed the SHIELD Portable, but otherwise has been the same since it arrived. However, it looks like that is about to change, as a SHIELD 2 has been spotted on a database, with a Tegra X1 SoC providing the power. This appears to be the SHIELD Portable 2, and with NVIDIA's latest and greatest Tegra chip running the show, should be quite the powerhouse. The Tegra X1 has 256 Maxwell cores for the GPU and a 64-bit, eight-core ARM CPU, and can display 4K video at 60Hz. Oh, and it supports DirectX 12. It's the same chip that runs the SHIELD Android Gaming Console, so its inclusion in a smaller device should be quite stunning.

Unfortunately there is not a whole lot else to go on, as outside of the Tegra X1, wireless bands (802.11 a/b/g/n/ac), and is evidently codenamed Loki, we don't have any other details. A full reveal could potentially come during Computex or E3 in June, but until then we just have rumors. Be sure to keep watch here for when NVIDIA officially takes the wrap off the SHIELD Portable 2!

Comcast has announced its latest entry into the growing fiber to the home Internet market with Gigabit Pro, a 2Gbps service. The service will debut in Atlanta, GA to more than 1.5 million customers, with plans to expand to 18 million homes by the end of the year. The 2Gbps speed is double the speed of Google Fiber, which has plans to add Atlanta to its growing number of supported markets. Installation of new equipment will be required, though pricing for the equipment and service were unavailable at this time. Executive VP for consumer services Mercien Jenckes described the strategy stating, "Over the coming months and years you can expect us to be aggressive, but deliberate, about rolling out gigabit and multi-gig services across the country."

Do video games cause people, especially children, to act violently has been a debated question for years, and will likely continue to be debated for years to come. Both sides have evidence they turn to, and researchers at the University of Oxford have contributed a little more. This research though falls somewhere in the middle though.

The main point of the debate is if violent video games cause people to act violently, or at least if there is a link between in-game violence and real violence. The Oxford researchers did fail to find such a link with gameplay, but the time spent playing was linked to problem behavior. This problem behavior includes hyperactivity, getting in fights, and a lack of interest in school. However, the researchers note that while this link is statistically significant, it is still a minor factor on a child's academic progress and emotional wellbeing. The researchers also found that playing for less than an hour a day could encourage better behavior, and that some kinds of gameplay seemed to discourage emotional and social problems.

The findings support the recommendation that parents pay attention to the amount of time children spend playing games. To perform the study, the researchers had some 200 students from 12 to 13 years old fill out a survey on their gaming habits, and had their teachers report on their behavior.
