Superconductivity is a phenomenon that could drastically change the world, when we can finally get it to occur at room temperatures. Currently the only materials capable of conducting electricity without resistance must be chilled to very low temperatures to do so. Researchers at the University of Illinois, Chicago, Cornell University, and Brookhaven National Laboratory have recently made a discovery about a fundamental aspect of superconductivity that could one day help raise the critical temperature.

Superconductivity is achieved when electrons couple with each other to form Cooper pairs. These pairs are able to travel without resistance, but exactly what keeps them together is not known. By using a technique called quasi-particle spectroscopy on a superconductor made of cerium, cobalt, and indium, the researchers were able to make key measurements of the pairs. What they found was that the bond between the electrons is highly directional, so in some directions they are bound to each other, and in other directions they are not. According to the researchers, this implies it is magnetism that holds the pairs together, as it too is highly directional, which agrees with a thirty-year-old hypothesis about Cooper pairs.

Through this understanding of Cooper pairs, it may be possible to remove some of the complexity of superconductivity and enable the critical temperature to be tuned upward.

Balance is a goal many wish to achieve, and that is not limited to people. Many physical systems try to achieve balance or equilibrium, but many also must exist in a state of non-equilibrium to function. Such non-equilibrium systems are not well understood in part because of the limitations on creating them, but researchers at Northwestern University have found a new way to do so.

A system at equilibrium has no potential and no energy, as any change in one direction is met by a change in the other. A non-equilibrium system is constantly changing though, as energy is continually being added. Examples of such systems include the Earth's plate tectonics, airplanes, and even the human body. Theoretically, the constant adding of energy will allow structures to be formed within a non-equilibrium system, and the Northwestern researchers found a way to test this. They made a mixture of pH-responsive particles, which will change their electric charges when pH levels are altered. This oscillation provides the energy input needed to form the non-equilibrium structures predicted.

As you may be able to guess, non-equilibrium structures are impossible to create under equilibrium conditions. This discovery could enable these structures to be designed by scientists, by tuning the oscillations adding the necessary energy.

For about as long as I can remember, I have worn glasses that have corrected my vision very well. Not everyone is so lucky though, with some people actually requiring glasses or contact lenses to view displays. Researchers at the University of California, Berkeley have recently developed a display technology that could help these people by shifting the vision correcting to the display.

Vision correcting displays have been developed by many groups over the years by using multilayer displays and light field displays. These do not always correct the images perfectly though or can produce a sharp but low contrast image. What the Berkeley researchers have created is a light field display that takes advantage of pre-filtering to create a sharp image, without sacrificing contrast. Basically the image of the basic display is manipulated mathematically so that a pinhole screen on top of it will work with the user's eyes to produce a sharp image. The key to this work is that mathematical pre-filtering. To anyone other than that user though, the image will look quite bad.

By adding eye-tracking technology to this system, the researchers hope to address the issue of head positioning, so that no matter how the user looks at the screen, the image will be sharp. Already though they know their method can be applied to help with a variety of complex visual problems.

Although EA Access was announced and made available to a limited number of Xbox One owners yesterday, Electronic Arts failed to reveal any relationship between the new program and the PlayStation 4. Apparently Sony is to blame for this, as a company spokesperson revealed today that Sony does not see EA Access as a valuable option for PlayStation 4 owners. According to Sony, PlayStation Plus memberships are up more than 200 percent since the initial release of the PlayStation 4, and the subscription model offers more value to gamers with PlayStation 4 consoles than EA Access does.

Due to this revelation, it seems fairly certain that EA Access will not be coming to the PlayStation 4 anytime soon.

Crytek Confirms Homefront IP Acquisition by Koch Media; HUNT: Horrors of the Gilded Age Moving to Crytek Frankfurt

Earlier today, Deep Silver and Koch Media announced that it had acquired the Homefront IP from Crytek less than a week after Crytek revealed it was going through a "transitional phase." Crytek has now released a statement that confirms the acquisition, as well as addresses the rest of the changes taking place at the company. First off, Crytek says that in accordance with English law, the Homefront team from Crytek's Nottingham studio will be transferring over to Koch Media's newly formed Deep Silver Dambuster Studios to continue their work on Homefront: The Revolution; though the deal still has to be finalized.

The other major change is that development of HUNT: Horrors of the Gilded Age will be moving from Crytek USA in Austin to Crytek Frankfurt, the company's headquarters. However, Crytek will retain a smaller presence in Austin, "with several staff members maintaining the CRYENGINE support team to assist North American licensees." Those that are not part of the support team are invited to apply for new positions at Crytek in Germany. Crytek's studios in Budapest, Istanbul, Kiev, and Sofia will be untouched, but "a closer collaboration between Crytek's studios in Shanghai and Seoul is under review."

Crytek founder and CEO, Cevat Yerli, said: "As we look to cement Crytek's future, this strategic deal with Koch Media would allow us to continue with our ambitious goals to become an online publisher. With Warface, Arena of Fate and HUNT, we believe we have the perfect portfolio and teams to make that happen. We would like to thank all our staff – past and present – in both Nottingham and Austin for their contributions to the company, and we wish all the very best to anyone who may no longer be under the Crytek banner moving forward."

Deep Silver Acquires Homefront IP from Crytek; Homefront: The Revolution Now Being Developed by Deep Silver Dambuster Studios

Remember last week when Crytek said it wasn't in financial trouble and was simply going through a "transitional phase" from being a development studio to an "Online-Publisher"? Well now things just got a whole lot more interesting. Publisher Deep Silver and parent company Koch Media announced today that it has acquired the Homefront IP from Crytek, and that development of Homefront: The Revolution has been moved to a new studio, Deep Silver Dambuster Studios. Crytek had acquired the Homefront IP in January 2013 for over $500,000 during the THQ auction, after Crytek UK had already been working on Homefront: The Revolution before THQ went belly-up. In June, Crytek announced that the game was being co-published with Deep Silver, but apparently that falls solely on Deep Silver's shoulders now.

According to Deep Silver, Dambuster Studios is a new studio formed specifically to take over development of Homefront: The Revolution, and is located in Nottingham, UK, the same city where Crytek UK is located. It is unclear whether any Crytek UK employees are moving over to Dambuster Studios, but I doubt the locale is a mere coincidence. Deep Silver Dambuster Studios is the third development studio within the Koch Media Group, joining Deep Silver Volition (Saints Row) and Deep Silver Fishlabs (Galaxy on Fire). "We are thrilled to see another great IP joining the Deep Silver universe," says Koch Media CEO Dr. Klemens Kundratitz. "We strongly believe in the potential of Homefront: The Revolution and trust in the new team to continue the path we have been walking in the last years."

Homefront: The Revolution is being developed for Windows PC, PlayStation 4, and Xbox One, and is expected to arrive sometime in 2015. It is unclear whether this news will affect the time table.

Batteries are a big deal today as without them we could not have cellphones, laptops, and many other advanced pieces of technologies. While batteries have enabled these technologies, they also limit them by needing to be recharged for continued use. Researchers at Stanford University have recently made a discovery that could lead to batteries with substantially greater lifespans than what you can find today.

Lithium-ion batteries are very popular today because they are rechargeable and can store a great deal of energy. Within each of these batteries is an electrolyte, containing lithium ions, an anode and a cathode, likely made of graphite of silicon. While those materials work well for the anode, researchers have known for some time that lithium would make a better anode, but lithium poses two challenges. One is that as a lithium anode would absorb lithium ions from the electrolyte, the anode would swell to such a size that it would fracture, which could lead to a short circuit as lithium ions escape from the fractures, forming dendrites. The other is that lithium is so reactive that it would use up the electrolyte and shorten the battery's lifespan. To solve both these issues, the Stanford researchers developed domes of carbon to surround the lithium anode, forming a nanosphere. As the nanospheres are flexible, they will survive the swelling but block dendrites from forming, and because they are not chemically reactive, the lithium ions will not chemically react with the anode.

Potentially a lithium anode battery could enable phones to have double or triple their current lifespan, or drop the cost of electric vehicles by requiring fewer batteries to achieve a three hundred mile range. Currently though, the cycling efficiency of the battery is not high enough for commercial use yet, but you can believe many are working to get it there.

Call of Duty: Advanced Warfare Campaign Story Trailer Shows a World in Chaos; Three Collector's Editions Announced

With release roughly three months away, Activision published the official Campaign Story Trailer for Call of Duty: Advanced Warfare yesterday, showing a world in chaos and a corrupt military corporation called Atlas taking advantage of the situation and abusing its power. At the helm of that corporation is none other than Academy Award winner Kevin Spacey.

Alongside the trailer release, Activision has announced three collector's editions for the game: Atlas Pro Edition, Atlas Limited Edition, and Atlas Digital Pro Edition. All three versions include the Atlas Gorge bonus multiplayer map and Atlas Digital Content Pack, which includes the following Atlas Corporation-themed content: two weapons (Bal-27 AE Assault Rifle and Atlas 45 AE Pistol), Atlas Exoskeleton, Atlas Helmet, Atlas Player Card, five bonus Supply Drops, and a single player Exoskeleton Upgrade Token. The Atlas Pro Edition and Atlas Limited Edition also come with: a Welcome to Atlas: Advanced Soldier Manual, which includes concept artwork alongside historical and tactical information; a Collectible SteelBook "featuring premium in-game artwork"; and a digital copy of the Official Call of Duty: Advanced Warfare Soundtrack. What separates the two editions is that the Atlas Pro Edition includes the CoD:AW Season Pass, which will include four action-packed DLC Map Packs. The Atlas Digital Pro Edition also includes the Season Pass, alongside the aforementioned digital content.

Atlas Limited Edition Atlas Pro Edition

The Atlas Limited Edition has a suggested retail price (SRP) of $79.99, the Atlas Digital Pro Edition has an SRP of $99.99, and the Atlas Pro Edition has an SRP of $119.99. For comparison, the Standard Edition has an SRP of $59.99. The Standard Edition, Atlas Limited Edition, and Atlas Pro Edition are currently available for pre-order, while the Atlas Digital Pro Edition will be available for pre-order at an undisclosed later date.

Call of Duty: Advanced Warfare is launching on November 4 for Windows PC, PlayStation 4, and Xbox One, with those versions being developed by Sledgehammer Games. PlayStation 3 and Xbox 360 versions are being developed by High Moon Studios, but it is still unclear if those will be arriving on that same day. Activision has announced that there will be a worldwide reveal of Advanced Warfare's multiplayer on August 11.

Natural gas and its components are valuable resources, but are tricky to work with because they are gases. Refining and converting the hydrocarbons into liquid fuels can be done, making storage and transport easier, but the processes involved require high pressures and temperatures. Researchers at Berkeley Lab and many other institutions have recently developed a proof-of-principle catalyst that drops the requirements, and could improve access to these liquid fuels.

Natural gas is comprised of many hydrocarbons, including methane and ethane, the latter of which can be converted into ethanol. That conversion process is expensive due to the 200-300 ºC temperature requirement, so the researchers have been working on a catalyst to ease the process. What they have developed is a metal-organic-framework (MOF) with iron attached, forming Fe-MOF-74. The structure of MOFs is like a cage, which enables them to act as a filter for other molecules, and have a large amount of surface area to absorb gases and liquids. The iron atoms inside the cages act as a catalyst for producing ethanol from ethane, reducing the temperature requirement to just 75 ºC.

With such a reduction in temperature, this discovery could drastically reduce the cost of converting natural gas into liquid fuels. Those fuels, which are generally clean burning, can then be stored and distributed more easily.

Ubisoft released a new Assassin's Creed Unity trailer today that introduces us to a young noblewoman name Elise, "determined to secure her place in the Templar dynasty amidst the chaos of the French Revolution." The trailer shows protagonist Arno Dorian racing over the rooftops and through crowds to prevent the beheading of Elise, who is apparently a central character to the game's story.

Elise will also star in the next Assassin's Creed novel by Oliver Bowden, told from her point of view and creatively titled Assassin's Creed Unity. If you still can't get enough of Elise, Ubicollectibles has designed an "Elise: The Fiery Templar" figurine, which can be assembled into a diorama with the "Arno: The Fearless Assassin" figurine.

Assassin's Creed Unity will release on October 28, 2014, for Windows PC, PlayStation 4, and Xbox One. The "Elise: The Fiery Templar" figurine will be released on October 14, while the novel will be available in November.

Magnets have quite a number of uses, from entertaining and educating students to storing data. Magnetism itself is the result of the magnetic moments, or spins of particles in a material aligning. Researchers at MIT have recently found a phenomenon to do with magnons that can be used to cool magnets, remotely by a magnetic field.

Magnons are quasiparticles representing the collective spins of particles within a magnet. These quasiparticles are able to move through a magnetic when exposed to a magnetic field gradient. What the MIT researchers realized is that when the magnons move, they take heat with them, cooling part of the magnet. From this idea they built a theoretical model based on the Boltzmann transport equation, which has to do with electron transport in thermoelectrics, and plugged in numbers found in previous research papers. The results suggest that though small, the effect does create a cooling effect from a moderate magnetic field gradient.

Currently this work is purely theoretical, so we cannot expect to be cooling our electronics with it any time soon. It will likely first find a use in cryogenic systems, as the effect is more pronounced at low temperatures.

Back in January, the indie studio Two Tribes, best known for the Toki Tori series, announced that the company was being rebooted. In short, Toki Tori 2+ took way longer to develop than expected and never achieved the sales the company needed to stay afloat. Parent company Two Tribes Publishing remained intact, but the development studio shut down and a new, smaller one was created. At the time, we were told that a "much smaller team" was working on the company's next game, " a 2D side scrolling shooter, which will be re-using the existing Toki Tori 2+ engine," thus decreasing development time. Today, Two Tribes finally unveiled what that new project is: RIVE.

RIVE is "the metal wrecking, robot hacking shooter" – a 2D shooter/platformer where "players learn to alter the behavior of their robotic enemies by collecting and uploading hacks." And it's all being created by a "base team of just three people." Check out the Announcement Trailer:

RIVE will be coming to PC via Steam and "all current consoles." No release date has been stated, but the game will be playable at Gamescom next month.

Chemical sensors are very valuable tools for many situations, including protecting against bombs at airports and other public areas. Sometimes the sensors are expensive, manmade devices, requiring well-trained users, and other times trained dogs are used. Researchers at Tel Aviv University though have developed a new sensor that is cheap and easy to operate, while being significantly better than the alternatives.

The device the researchers built is a tiny chip with clusters of transistors on it. These transistors have been designed so that when a single molecule contacts them, it binds to them and affects their conductance. This change makes it possible to detect and even identify the molecule caught from the air, all in real-time. The chip is so sensitive to the molecules that it can detect some in concentrations approaching parts-per-quadrillion, which is orders of magnitude better than other chemical sensors, and even dogs noses.

Thus far the prototype sensor has been tested against commercial blasting and military explosives, as well as some improvised explosive materials. By being faster, cheaper, and giving users the ability to identify detected chemicals, this sensor could go a long way to keeping people safe.

BioWare plans on releasing a series of videos for Dragon Age: Inquisition that each focus on one particular gameplay feature. The first such video, released today, focuses on combat. Considering a lot of the backlash for Dragon Age 2 focused on the simplified combat and removal of the tactical view present in the PC version of Dragon Age: Origins, this seems like a good starting point for the "Gameplay Features" series. And indeed, if you played the PC version of DAO, you'll likely be very pleased by what's shown in this new video:

Dragon Age: Inquisition will launch on November 18 in North America and November 21 in Europe for PC, PlayStation 4, Xbox One, PlayStation 3, and Xbox 360. The Standard Edition costs $59.99 for all platforms, while a Deluxe Edition is available for $69.99 and includes the following bonus content: Flames of the Inquisition Armor, Flames of the Inquisition Armored Mount, Skyhold Throne, Red Hart Halla, Bog Unicorn, and the digital soundtrack. Pre-ordering either version grants you some nice fiery weapons from the Flames of the Inquisition Arsenal.

Information can be very overwhelming for humans, which is part of the reason computers were developed, but even they can struggle. Massive datasets can slow even the best computers, and when results of some analysis are needed urgently, that can be a problem. Researchers at MIT though have developed an algorithm that can intelligently predict what information in a dataset will be useful, without the slow task of directly analyzing it.

To achieve this, the researchers turned to a probabilistic graphical model, which abstracts data into nodes, with connecting edges representing relationships between the nodes. By knowing the strength of the connections, one can quickly target what data is most valuable, and focus on them. Determining the strength can be complicated if nodes are connected by more than one path, creating a loop. To address this, the algorithm creates a spanning tree that dispenses with the loops and turns to Gaussian distributions to avoid distortion. It turns out that the probabilities represented by the graph are Gaussian, which means they can be described by their average value and variance. The uncertainty of the problem can be determined from the variance, but that does not require actually processing the data.

What all of this adds up to is a way to identify the most important and useful information in a dataset, without having to analyze the dataset. This results in the process being significantly faster, which could be very important if, for example, it is weather data being used to predict a storm's path that is being analyzed.

NVIDIA has developed a technique that uses two display panels with slightly offset pixels to improve the picture quality of low resolution LCDs. The researchers combined two 1280x800 LCDs with a polarization filter and custom software to help the panels act as one. The result is a "cascaded display" that "quadrupled the spatial resolution of the original panels." The new display resulted in an improved picture when compared to the original panels but still fell short of the source image.

Superconductivity is a phenomenon many in the world have been waiting anxiously for, but achieving it is difficult. Typically the materials that can become superconducting must be cooled to very low temperatures, but the hope is to one day find or design one that would work at room temperatures. Researchers at the University of California, San Diego have recently discovered an artificial crystal structure that should support superconductivity, and the principle behind it.

The structure the researchers describe is comprised of alternating layers of atomically thick layers of semiconductor and insulator. Specifically they describe the molybdenum disulfide as the two-atom thick semiconductor, with boron nitride being the few-atom thick insulator separating and cladding the semiconductor. When an electric field is applied to this structure, electrons and holes, the positively charged areas left behind by electrons, collect in the different semiconductor layers. Despite the separation, the electrons and holes are still bounded, forming indirect excitons. At a certain temperature, these excitons will achieve the coherent state of superfluidity, meaning that they will form a gas lacking any viscosity. This will also cause the phenomenon known as counterflow superconductivity.

What this all translates to is a blueprint for creating structures that become superconducting at a specific temperature. Presently that temperature is predicted to rest near that of other high-temperature superconductors, which is still pretty cold. As the blueprint can be applied to other materials though, it could lead to new understanding of superconductivity and other quantum phenomena.

Rust Developer Facepunch Studios Announces New Game, Riftlight

Rust is still in Early Access, but developer Facepunch Studios is already working on other games, which has stirred up a bit of controversy – although doesn't everything on the Internet these days? Let's forget for a moment that money brought in from Rust Early Access sales is going to fund other games instead of only being used to improve Rust – Facepunch's new game, Riftlight, actually looks kind of cool.

Riftlight is an arcade twin-stick shooter with "light-RPG stuff" like loot, character levels, abilities, and talent trees. Developer Adam Woolridge created a developer blog entry for the game, explaining that he wants it to be "colorful and different" and that there will be three different ship classes to choose from: Ranged, Caster, and Melee. The Ranged class would play similarly to what we've come to expect from a traditional twin-stick shooter, while the Caster will be a glass cannon, equipped with "cool spells and area of effect damage." The one that truly goes against the norm is the Melee class, which will be equipped with a close-ranged energy beam (sword) and centered around getting in close.

Each class has its own unique talent tree, which allows you to choose new abilities every few character levels. Each ability uses energy, which regenerates quickly over time, and many have cooldown timers, but each ship also has a basic attack from the start that is free to use, though generally less effective. In addition, the game will feature plenty of loot with randomly generated stats (and names). Based on the "placeholder inventory and stats screen," there seem be slots for weapon, hull, engine, shields, and power, along with three unnamed slots – definitely a lot of room for customization. Not only are the items randomly generated, but so are the maps. The plan is it to not just be random layouts, but also include random missions.

If all that sounds cool, even cooler is that you'll be able to bring along a friend...or two...or three. Online co-op for up to four players "needs a lot of improvement and more work," but it's already playable in the current alpha build. There is no ETA for a release, but Woolridge "want[s] to get a super-early playable version out so people can try it out." That won't happen until he has some more levels and content to play, nor is it clear whether that would be a demo download for free or if it would be another Early Access program.

While there's been a lot of outrage about Facepunch diverting resources to a new project, founder Garry Newman released a statement, assuring fans that Rust's development will not be affected and that the studio continues to push out new content and updates frequently for Rust. He also added more fuel to the fire, explaining that the studio actualy has "three other prototypes being worked on by Facepunch staff." A lot of the community anger stems from the fact that money from Rust is being used on these new projects, but Newman says it's no different than Apple taking money made from iPhone sales and funding development of the iPad. I'm not sure that's the best analogy considering iPhones are complete, finalized products, while Rust is not, but nevertheless, it is what it is. For better or worse, this is why Steam Early Access is such a controversial program – but hey, nobody is forcing anyone to pay for these "unfinished" games.
