Everybody is familiar with magnets and there is a good chance many of us are also familiar with what happens when a magnet breaks; you get two magnets. The reason breaking a magnet gives you two is that the magnet itself is made up of many smaller magnets, but when you get down to the size of atoms, magnetism is not as well understood. Researchers at the London Center for Nanotechnology have recently made a discovery about the directionality of magnetic atoms that could have many impacts.
For the magnets we deal with on a daily basis, the directionality or anisotropy or the magnet is determined by its shape. As atoms are incredibly small, it is hard to characterize a shape for them, which makes it hard to manipulate their magnetic anisotropy. At least that is what had been believed, but the LCN researchers have discovered the Kondo effect can also impact this property. The Kondo effect comes from a magnetic atom and metal coupling, and the researchers discovered the relationship measuring the anisotropy with a scanning tunneling microscope of cobalt atoms between a copper surface and atomically thin sheet of copper nitride.
Being able to affect the magnetic anisotropy of an atom could be very powerful, especially as the Kondo effect can be controlled and tuned electrically. This could lead to new kinds of magnets that rival the strength of rare earth magnets, without the rare and expensive metals.

It wasn't too long ago when Valve unveiled its Linux-based SteamOS and Steam Machines. Both are designed to make gaming more accessible in the living room, as well as introduce more people to the joys of PC gaming. At the time, Valve didn't say when exactly we could get our hands on these products, but now we know: SteamOS arrives tomorrow. The Steam Machine and Controller prototypes are also heading out tomorrow to the 300 lucky beta testers, who should already have received their confirmation email letting them know they were selected. These prototypes are high-end systems, however there will be a range of setups for any number of budgets.
Regarding SteamOS' impending arrival, Valve is warning that despite it launching tomorrow, "unless you’re an intrepid Linux hacker already, we’re going to recommend that you wait until later in 2014 to try it out." So, it kind of sounds like the initial launch of SteamOS is an early version, probably with some manual compiling required. None of the Steam Controllers will be available outside of the ones for the 300 Steam Machines beta testers, so the full experience will be a bit limited. In any case, SteamOS is nearly here, as are the Steam Machine prototypes. Full specifications of the Steam Machines will be revealed during a CES press conference on January 6, so be sure to tune in for that!

Changing shape can be a very useful ability in many situations, but can also be hard to achieve. After all, most materials will only deform when a force is applied to them, which means a mechanism is needed to apply that force. Researchers at Rice University though have created a composite material that can change its shape when heated.
The composite is made of two layers. One layer is a simple but important polystyrene, and the other is a liquid crystal elastomer (LCE). The elastomer is made of cross-linked polymers that align to an axis called the nematic director. When heated, the LCE will expand or contact along that axis, but because of the polystyrene, the expanding material cannot stay flat, but bends, wrinkles, or folds the entire material. By controlling the geometry of the polystyrene and the temperature it was applied at, the researchers found they could control the shapes the composite will take.
The ability to have a material change shape based on environmental conditions has potential applications in optics, biology, and medicine. For example, scaffolds and substrates for cells to grow on could be designed to react to different stimuli, and expand or contract as needed.

ECS introduced the Durathon suite of testing standards to set its motherboards apart from the competition from a reliability standpoint. With the Extreme Temperature Resistance testing conducted by ECS, motherboards are put through testing at temperatures ranging from 50°C to -10°C, which is 10°C higher and lower than industry standards. The wide range of temperatures used in testing shows that ECS motherboards are capable of operating under the most extreme environments at both ends of the temperature spectrum. When combined with the other Durathon tests, ECS hopes to have proven that its boards can be trusted to perform.
The Carbide Air 540 from Corsair is a mid tower case designed with a high airflow layout. The case was initially available in silver and black and is now available in arctic white. The case has two side-by-side chambers and as a result is wider than most cases. This gives enough room for the Direct Airflow Path layout which is "optimized to limit obstructions and streamline airflow from the intake fans to the hottest PC components." One chamber is home to the motherboard, GPU, and hot swap 3.5" drives while the other houses the power supply, SSDs, and 5.25" drives. The arctic white Carbide Air 540 is available now at an MSRP of $149.99.

While I doubt that physical controls such as keyboards and mice will ever go away, motion controls are growing more common and popular. The many motion control systems currently available use a variety of technologies, but most if not all rely on being able to see the user. That is not the case with WiTrack, a new system developed by MIT researchers as it can capture your motion through walls.
This is not MIT's first venture into motion tracking through walls, but the previous attempt, called Wi-Vi, relies on Wi-Fi signals. The new WiTrack system instead uses lower energy signals that allow for much higher accuracy. Specifically, it is able to determine a person's position to within ten to twenty centimeters. The hardware achieving this includes one transmitter and three receivers, while the software uses algorithms capable of filtering out echoes and identifying when the pulse of radio waves was emitted. Combined this is able to not only follow you behind a wall but also track gestures, so you can turn lights off in another room, just by pointing in the right direction.
It is easy to see the WiTrack technology being used for video games as well as monitoring elderly people at risk of falls, but its true potential may be far greater. This is in part because the radio signals it uses are of very low power (100 times less than Wi-Fi and 1000 times less than what cell phones use) and the physical technology is already cheap to produce, and could be made cheaper.

In most situations, we find that plastics are electrical insulators, but in the seventies it was discovered that some were actually semiconductors. Now researchers at Linköping University, and many other institutions around the world, have found a polymer that is a semimetal, which could affect the future use of thermoelectric devices.
Semimetals are a family of materials resting between metals and semiconductors, characterized by a small bridge between the conduction electron bands of their atoms, and the valence band. This means they do not have a band gap, but they also do not have much room for electrons at the energy level needed to conduct. The idea that a polymer can be a semimetal was first hypothesized a few years ago, when a high thermoelectric effect was measured in a polymer. This indicated it was a semimetal, but was not proof on its own. Bow the team of twenty scientists from around the world have confirmed that a doped version of the plastic PEDOT is a semimetal.
The high thermoelectric effect could have some interesting implications, in part because polymers are cheaper to manufacture, while the metals used in thermoelectric devices are quite rare and expensive. Now that we know the job can be done with polymers, a new field of organic electronics could grow.

Anyone who works with computers, cars, and many other devices can tell you how hot they get, and all of that heat is coming from wasted energy. For some time, people have been trying to reduce or capture that wasted energy, and thermoelectric materials, which can convert heat into electricity, can help. Sadly, thermoelectric materials are hard to produce, and thus have been limited to laboratories, but now researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM may be changing that.
For a thermoelectric material to be useful at capturing wasted energy, it has to have certain properties. Among these is ZT value, which relates to their efficiency, higher than one and the ability to withstand high temperatures without increasing resistance. One family of materials, called half-Heusler compounds, can satisfy these requirements, but have never been produced cost effectively before. That is what the researchers and their partners have changed by successfully producing the material, with most of the needed properties, in kilogram quantities.
With so many systems generating large amounts of wasted heat every day, it is obvious just how important this research could become. Hopefully it will not be long before these materials are fully, industry-ready.

The latest Snapdragon processor from Qualcomm, the Snapdragon 410, is the first in the processor line to feature 64-bit capable ARM cores. Built using the Cortex-A53 CPU and the ARMv8 architecture, the new SoC will run at around 1.2GHz. The Cortex-A53 is paired with the Adreno 306 GPU and four cores are packed into a single Snapdragon 410. The 28nm LP manufacturing process is used and results in a power efficient chip that should make its way into mobile devices in the second half of next year with retail prices under $150 a strong possibility.

Samsung recently released the latest edition of its Magician software, which is used to monitor and optimize Samsung SSDs. The newest version, version 4.3, brings two new features that are particularly interesting. One of them is RAPID (Real-Time Accelerated Processing of I/O Data). What that means is that it can boost your sequential read times by up to twice the speed of what it normally is, so some will experience sequential read times over 1 GB/s. The way Samsung achieves this boost is by utilizing a small amount of CPU power and RAM (around 50 MB) to cache frequently used programs, so they are available almost immidiately. The other new feature is TCG/OPAL, which an upgrade in the security department. OPAL protects the user's data against unauthorized access, when the data leaves the owner's control.
The software is available for download, and I highly recommend it, if you own a Samsung Pro or Evo, since my own sequential read speeds hit 1.2 GB/s after enabling RAPID.
Ideally, a user will use a different password for every online account they have, but the reality is that one person can have some many accounts, it is almost impossible for them to remember them all, without help. Some of these solutions though, can actually put your security at risk. Researchers at Carnegie Melon University however, have taken advantage of some cognitive research and built a system to aid a user's memory, without compromising security.
Our memory works by encoding information with connections, and generally the more connections, the more easily you can recall the information. For example, remembering a specific sentence is easier when the sentence is tied to pictures. This is what the researchers are using to help remember passwords, by creating an app that shows a user a few pictures, and asks them to create a story about a sentence long, based on the pictures. The password is then formed from parts of the sentence, such as the first letters. As the story is the key and only known to the user, the pictures do not need to be secured, but for further security, the app associates multiple image groups with one password, so the user will also have multiple stories associated with the password as well.
Currently the app is undergoing development as part of an undergraduate research project, but when finished, it could allow some to generate 126 different passwords, by memorizing just nine stories. There is one flaw to the system though, and that is the reliance on letters, while some sites require numbers, capital letters, or passwords of specific lengths. Just another bit of information to remember.

So often it seems in science that technologies start with the most expensive materials and tools, making it nearly impossible to take out of the lab. Of course there are reasons why expensive materials, such as gold and silver are used, but it is always welcome research to find another, cheaper material that can do the job just as well, or even better. Such appears to be the case with plasmonics and aluminum, according to some Rice University researchers.
Plasmons are a kind of quasiparticle, formed by the coupling of a photon and electron. This combination can allow the energy of a photon to flow over a metal as though it were an electrical current, which can be exploited for some interesting optical devices. Gold and silver nanoparticles are often uses in plasmonics, in part because they do not oxidize. Aluminum does naturally oxidize, which has prevented it from being adopted as the materials response to different light frequencies has seemed to change in prior studies. This new research indicates however, that that the optical response of aluminum nanoparticles is partially related to the amount of oxidation. As aluminum oxidizes only to a point, this means that the changes to a nanoparticle's optical properties eventually stabilize, in a predictable way.
The researchers also discovered that plasmons on aluminum nanoparticles will obey quantum mechanics across a larger range than silver or gold nanoparticles. This could have a great impact on the future of plasmonics, in more ways than just reducing costs.

Telltale Games, the studio behind popular episodic games such as The Walking Dead and Sam and Max, revealed that it is working on two new games based on well known franchises, Borderlands and Game of Thrones. The announcement came over the weekend at the VGX awards and today Telltale gave a little extra peak into what is to come with teaser trailers for both games. There isn't much, if anything, revealed about the stories from either game, but I am personally hoping that the Game of Thrones game follows Robert Baratheon and Ned Stark in the events leading up to the first book in that series.
Valve has released a brief teaser for its upcoming holiday event in Dota 2, Frostivus. You may remember that Frostivus was canceled last year and replaced by the Greeviling after it was ruined by those pesky Greevils. The teaser promises that this year will be even better than what was planned last year as Radiant and Dire gather to celebrate Wreath-Night and the Season of Givening. Valve even ends the teaser with a reassuring statement, "There is nothing more to worry about, nothing you need to do. Nothing can possibly go wrong."
Gravity is a very odd phenomenon, in part because we do not really know where it comes from or how it is able to affect spacetime the way it does. Further complicating matters is that the gravity described by the General Theory of Relativity is not compatible with quantum mechanics. Thanks to the recent work of other researchers, some at MIT have developed a new theory concerning worm holes and quantum entanglement, which may explain the source of gravity.
The recent work considered what would happen if two black holes were entangled, and then separated. The conclusion of that work was that a wormhole would form between them, allowing information to be shared by the two objects, no matter how separated they are. The MIT asked a similar question, but worked with quarks, which are sub-nucleonic particles, and what would happen if they were entangled and separated. The researchers first mapped this onto a four-dimensional space, representing the one we live in, but then determined what it would look like in a fifth-dimensional space. The result was a wormhole.
As wormholes are believed to be connected by gravity, and that gravity exists in five dimensions, this conclusion could suggest that gravity originates from quantum entanglement. Just the idea that entanglement leads to some kind of geometry suggests some interesting questions, but if it does indeed lead to gravity, then the answers could be far more intriguing.
The second week of December is upon us, and so are a number of reviews and articles for you to check out. We have another look at the Sapphire R9 280X Toxic video card, with its custom cooler and factory overclock to help get you gaming at the best settings possible right away. There's also a review on the NZXT H630 Silent full tower case, which has plenty of room for whatever hardware you'd like to install while keeping it all pretty silent. The Fractal Design Node 304 White computer case gets reviewed too, which is a mini-ITX case for those who want a much smaller footprint than most other computers. There's also a look at the Lenovo IdeaPad Flex 14 Ultrabook, a convertible laptop so users can better take advantage of its touchscreen. Finally there's an article examining whether or not you should get a sound card for your system.

Black holes have been a part constant of science fiction for as long as I can remember, with storytellers using them as means to travel across the Universe and even to other universes. Of course, these concepts just exist within the realm of fiction. The reality of black holes though may be a bit weirder than expected, according to researchers at the University of Washington.
Quantum entanglement is an interesting phenomenon which links the quantum states of two particles. This means that the properties of one will dictate those of the other, when they are observed, no matter how physically separated the two particles are. What the researchers have done is considered what would happen if two black holes were entangled, and their conclusion is that a wormhole would form. The catch is that you would not be able to transport any information through the wormhole, because black holes do not allow light to escape. However, if you and a friend were to jump into the two black holes, what you would see and experience inside would be identical.
Perhaps this research will dash the hopes of some readers and writers, but it will likely increase our understanding of entangled quantum systems. Forming this theory required showing a relationship between quantum mechanics and classical geometry, which will be a useful tool for other researchers.

Google is in the process of rolling out the ability to download e-mails and calendar appointments from its Gmail and Calendar services with the click of a button to give users access to their data offline. E-mails will be exported in MBOX and Calendar data will be in iCalendar format, two widely accepted and used formats for this type of data. The downloaded data can be used to move to another service in addition to having offline records. Calendar data can be exported immediately while Gmail download support will be rolled out over the next month.
Hackers managed to obtain more than two million passwords from popular online destinations such as Facebook and Gmail in a breach that began on October 21. The attack was carried out by using keylogging software on the users computers and 93,000 sites in total had passwords compromised. Users that had their accounts compromised were notified by the sites in question and were advised to change their passwords. Trustwave, the company that discovered the hack, has stated that there are more servers out there that haven't been found yet, indicating that the hack is likely ongoing. Be sure to keep your computers up to date and mix up your log in information for all of the sites that you frequent to help prevent or minimize the damage that could be done in attacks like these.
First introduced in the 1970s, fiber optics has provided the world with high speed communication, and is now part of the backbone of the Internet. Since its introduction, the capacity of the technology has increased by an order of magnitude about every four years, through the development of associated technologies. Recently though, that trend has slowed as researchers have hit a bottleneck, but those at EPFL have found a way to greatly improve throughput in one advancement.
A datum traveling through an optical cable is represented by the presence or absence of a light pulse. This is works well for digital data, which is stored as zeroes and ones, but to protect the integrity of the data, each datum must be enough separated from the others that they will not interfere with each other. That means there is a fair amount of empty space in an optical signal. What the EPFL researchers have done is demonstrate an efficient way to reduce the necessary distance between two data. By making the pulses rectangular, so they are equal intensity over a range of frequencies, it is much easier to keep prevent interference, that would otherwise corrupt data.
The idea of creating these 'Nyquist sinc pulses' in optical fibers is not new, but this is the first time it has been achieved with nearly perfect rectangular pulses, and without a complicated infrastructure supporting it. To deploy this solution in an optical fiber network one would just have to replace the transmitters in the system, not the cables, and the new ones would be using technology that has already matured.

Func is no longer just a company that makes some stellar mouse pads, as it's released a mouse (the MS-3) and now a mechanical keyboard. The keyboard is called the KB-460, and it uses Cherry MX Red mechanical switches with individual key illumination. There's also full N-key rollover on the KB-460, so you won't have to worry about any commands getting missed during a frenetic gaming session. Customization is a key part of this keyboard, as Func not only allows you to adjust the backlighting level, but you can also re-assign the keys to whatever suits you best. Want certain keys remapped or disabled altogether? You can do that! There are five profiles to store your settings, with the 128KB of onboard memory keeping everything there regardless of where you take the KB-460.
The keyboard features a Func Mode (hold the Fn key and hit F12), which activates any re-assigned keys and disables the Windows button. Everything can be configured with the Setting Software, however if everything is already to your liking, you can just plug in the KB-460 and get right to typing/gaming. Func wants users to feel at ease with the KB-460, and to also customize it to their needs (hence the re-assigning function). There are a multitude of key layouts available for the KB-460; so US, UK, Nordic, French, German, and Russian users can have the exact keyboard they need. The vast majority of the pictures below are with the Nordic layout, however you can check out all six on the keyboard's website.
Each Func KB-460 has a 1.8 meter braided cable and two USB 2.0 passthrough ports, plus a palm rest. Retail price on the KB-460 is $99.95 at launch ($119.95 afterwards), with availability starting today.

There are many situations where you want to measure the distance to an object, such as surveying or controlling an autonomous car. A common tool for those situations is the lidar rangefinder, which reflects laser light off of objects to make the measurement. Researchers at MIT have recently made some clever advances to the system, enabling it to use significantly less light, which should have some interesting benefits.
A typical lidar system will repeatedly fire laser pulses at a position, until it gathers enough consistent data to be confident in the distance, and moves on to another position. The new MIT system however only accepts one photon before moving on, but records number of pulses it fired before receiving the photon. This allows it to generate a map based just on that data, roughly indicating the reflectivity of different objects. Of course, capturing only a single photon puts the system at risk of being fooled by a stray photon, from another source. To correct for that the researchers are applying a statistical trick that takes advantage of the fact that such photons follow a pattern known as Poisson noise. Instead of just filtering out the noise pixel-by-pixel, this system considers how much filtering was required in adjacent pixels, as they will likely have similar reflective properties, at the same depth.
Altogether, this new system should be able to generate a depth map with just a hundredth the number of photons a conventional lidar system uses, and generate an image with one nine-hundredth the number of photons. This should result in energy and time savings, and should prove useful in low-light situations.
It's nearly the end of the first week of December, and before it arrives there's a few items for you to look over. We have a review on the HIS R7 250 iCooler Boost Clock video card, which could be an ideal card for those on a tight budget who need something more powerful than integrated graphics. There's also a look at NVIDIA GRID on the SHIELD, which recently arrived in beta, to see how far cloud gaming has come and just what NVIDIA's take on it is like.

Valve is going all in with Linux, as it has officially joined The Linux Foundation. The Linux Foundation is a nonprofit group comprised of companies and individuals that promote and advance the open-source OS. Valve's upcoming SteamOS is Linux-based, and its new Linux Foundation membership further cements the investment in gaming on Linux. The membership does give the company some benefits, as Valve can help guide development through workgroups and member councils. Valve's Mike Sartain had the following to say on the move:
Joining the Linux Foundation is one of many ways Valve is investing in the advancement of Linux gaming. Through these efforts, we hope to contribute tools for developers building new experiences on Linux, compel hardware manufacturers to prioritize support for Linux, and ultimately deliver an elegant and open platform for Linux users.
No details were released on just what Valve paid to join, however corporate membership begins at $5,000 and goes to $20,000 for the lowest Silver tier. Platinum membership is a $500,000 deal, which grants a seat on the board. Right now Valve is the only pure game company in The Linux Foundation, although both Sony and AMD are members. Other members include IBM, Oracle, Cisco, Google, and Samsung, so there are some definite heavy hitters helping advance Linux. Considering how much Valve CEO Gabe Newell is a fan of Linux, it looks like gamers will soon have a worthy OS to use for their favorite hobby (and personal Steam Machine).
