Noctua Introduces Third Generation S12 Series Quiet Case Fans Noctua is one of the most recognizable names in the computer world, with products designed to keep your system cool and quiet. Today, the company is introducing the third generation of its S12 series quiet case fans: the NF-S12A. These new fans have a "further refined blade design" and Anti-Stall Knobs that work with the new Advanced Acoustic Optimization (AAO) frame. Basically, the NF-S12A improves the airflow/noise efficiency of past models by eight percent. Its Anti-Stall Knobs "reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan's stall margin." Performance is improved on both heat sinks and radiators with the Anti-Stall Knobs, so everyone can check them out regardless of air or water cooling. The new AAO frame features integrated rubber pads to reduce vibration and Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures to increase performance. The Noctua NF-S12A fans are available today for $21.90. There are three variations available: NF-S12A FLX, NF-S12A ULN, and NF-S12A PWM. The FLX model can operate at 1200/900/700RPM thanks to the Low-Noise Adaptors, the ULN runs at 800/600RPM for anyone needing silent operation, and the PWM features the NE-FD1 IC for automatic fan control via 4-pin headers. That last one also comes with a Low-Noise Adaptor to drop the maximum RPM from 1200 to 900. Read More ...
Watching Proteins Unfold Diseases occur for many reasons, including bacteria, viruses, mutations, and incorrect protein folding. Proteins are among the most important molecules in biology as they are what perform or trigger a cellular process, and their operation is determined by both their chemical makeup and their structure. Diseases such as Alzheimer's, Parkinson's, and Huntington's are all the result of misfolded proteins, which is why researchers are trying to understand how proteins fold and those at the Max Planck Institute for Biophysical Chemistry have taken an impressive step towards that end. A good way to satisfy one's curiosity about something is to watch it happen, but proteins are so small you cannot see them with a microscope. Also you have to be able to trigger protein folding while you are watching, and methods involving high temperatures and pressure can cause the folding to occur too rapidly to see. To trigger the folding, the Max Planck researchers decided to use low temperatures by cooling their sample from 25 ºC to -16 ºC and then used Nuclear Magnetic Resonance (NMR) spectroscopy to watch what happens. The researchers found that as the protein, CylR2, was cooled it broke into two subunits which were stable, at first. As the temperature dropped further, these intermediate subunits become unstable and dynamic, which may then lead to the incorrect protein folding that causes disease.

NVIDIA Offers Content for Free to Play Games NVIDIA is currently offering in-game content for three free to play games to gamers that purchase a new NVIDIA GPU. The three participating games are Hawken, World of Tanks, and Planetside 2. A purchase of a GTX 650 series card will give $25 to spend in each game while a GTX 660 or better will give $50 per game. This is an excellent deal to keep in mind when purchasing your next card or for giving you a new game to consider. Read More ...
CyberPower Announces FangBook X7 Gaming Laptop CyberPower has announced the addition of a new laptop to its mobile gaming lineup, the FangBook X7. The laptop is powered by an Intel i7-3940XM Extreme Edition CPU and an NVIDIA 680M GPU. This pair of components puts the FangBook ahead of many desktops in power, and ahead of nearly all laptops. A 17.3" 1080p LED screen provides anti-glare viewing while included speakers and subwoofer provide great sound. The system can hold up to 32GB of RAM and 2TB of hard drive space. NVIDIA Optimus technology will help to conserve battery life as much as possible with the power hungry components included in the system. The FangBook X7 has a number of starting models with the cheapest option having a base price of $1,299. Source: CyberPower Read More ...
Intel Plans New Internet TV Service Intel has today announced plans to build its own internet TV service. Erik Huggers, Head of Media at Intel announced these plans during the AllThingsD media conference, however did not comment on any particular details. The company is also designing a set top-box to work hand-in-hand with the service. Rumours have been circulating to this effect for a while now, but, until now, nothing has been confirmed. From the information currently available, it would appear that Intel's TV service will be very similar to current offerings, but Huggers emphasised Intel's focus on giving users "choice, control, and convenience" with their TVs. This is not Intel's first attempt to gain traction in the TV industry, its processors already feature in a number of early smart TVs. In 2011, however, Intel shut down its TV division, but this may have allowed them to focus on development of their own service. Source: CNET.com Read More ...
Monolayer Light Emitting Triangles Created Structure is an important characteristic of any material as different structures can produce different properties, even though it is the same atoms and molecules involved. Carbon may be the best example of this as its allotropes of graphite, diamond, and graphene all show surprisingly distinct properties, but it is not the only material like this. That is why researchers are constantly trying to change things up to see what they get and that includes trying to make atom-thick sheets of a material. Researchers at Penn State have recently created a monolayer of tungstenite and in this form it could have many optical technology applications. Tungstenite is a naturally occurring but rare material made of tungsten disulfide (WS2) and the researchers produced atom-thick sheets of it by exposing tungsten oxide to sulfur vapor, heated to 850 ºC. The resulting monolayers had a honeycomb pattern of triangles that were photoluminescent, so when one color light fell on them, another color would be emitted. Interestingly, the light was primarily emitted at the edge of the triangle, where the chemistry of the triangles changes. Also the triangles emitted light at room temperature, which could be very valuable depending on what the material is used for. Potentially the tungstenite triangles could be used for optical light detection and emission, similar to LEDs and lasers. The researchers are also looking at other means of producing tungstenite to see if combining it with other materials can produce even more valuable properties. Source: Penn State Read More ...
