Record Wireless Data Transmission
For many of us, the Internet likely enters our homes via a physical cable, but for many people, this is not the case. Connecting rural areas can be a very expensive task as so much equipment has to be installed. Wireless communication however is a cheaper alternative, and researchers at the Fraunhofer Institute for Applied Solid State Physics have recently set a new record of 100 Gbps over the air.
To achieve this record, the systems starts by generating two laser signals, which are superimposed on a photodiode. The photodiode then produces an electrical signal with a frequency matching the difference between the two laser signals, 237.5 GHz. That electrical signal is then transmitted by an antenna to a receiver with integrated circuits containing high-electron-mobility transistors. These transistors are able to operate with signals with frequencies between 200 and 280 GHz, and the chips are able to work with advanced modulation formats, which means the wireless system can be integrated into optical fiber networks in a bit-transparent way.
Through this combination of technology, the researchers were able to reach 100 Gbps over a distance of 20 m, and that is just the beginning. Advances will allow for greater range and definitely greater speeds as multiplexing methods are added.

CPU Graphics Show Off at IEM New York
The latest stop of the Intel Extreme Masters gaming tour took place at the recent New York Comic Con and saw professional gamers go head to head in games like StarCraft 2: Heart of the Swarm. The tournament was won by Startale Life, who defeated Naniwa of the The Alliance 4-2. Another story to come out of the weekend was that all games were played on systems using Intel Iris Pro graphics. The CPU based graphics of the Iris Pro 5200 were paired with an i7 4750HQ in a Cyberpower Zeus Hercules laptop. The games were all played at 1080p resolutions and according to Laptop Magazine, "the Iris Pro machines easily handled the demanding tasks thrown at them during the tournament without any hiccups."

3DMark Now Available for Windows RT
3DMark, the popular benchmark tool from Future Mark, is now available as a free app for Windows RT devices in the Windows Store. With the new application users can determine how well devices like the Surface 2 perform, and can even compare benchmarks across platforms. This version of the benchmark includes three tests that will put your system under a varying amount of stress. Ice Storm uses DirectX 11 running at 720p for graphics testing. Ice Storm Extreme bumps up the resolution to 1080p and uses higher quality textures and effects. Ice Storm Unlimited cranks up the stress even higher to really bring the system to its knees.

Bringing Genetic Analysis to a Device Near You
Our genetic code contains a great deal of information about us, including where our families are from and what diseases we are predisposed to. If you want to learn this information about yourself, you will have to use one of multiple services to sequence your genome, and wait for select results. Researchers at Tel Aviv University though want to change that by putting part of the analysis in the palm of your hand.
At present, when you have genetic tests done, only specific sequences are analyzed, and if you want some new tests run, you need to provide a new sample. The GeneG app and website however are being designed with a different approach in mind, where your entire genome is sequenced and stored to your profile. This way, new tests can just be applied to the existing data, without a new sample. Also this gives you and by extension your doctor quick access to your genomic data. As medicine goes advances towards pharmacogenomics, where treatments and drugs are customized to a patient's genetics, this could be an invaluable tool.
The researchers are planning to release the GeneG service to doctors this month and later to the public. The website and a demo app are presently available, for those curious about the subject.

Cooler Master Expands PSU Line Up With New GM Series
A new addition to Cooler Master's PSU line up has been released. Called the GM Series, it will be available in 450, 550, 650, and 750 W capacities. The PSUs will be semi-modular and have an 80PLUS Bronze certification. On top of that, they will use a unique 3D circuit design that will reduce the amount of unnecessary internal cabling, which in turn reduces crosstalk and signal noise, while allowing for better airflow to critical components. The GM Series will be based on a single +12 V rail design with a DC-DC module that increases voltage stability and overall efficiency. Furthermore, the PSUs will support C6/C7 sleep state along with a zero load operation feature, which ensures Haswell compatibility.
The PSUs will be cooled by a single 120 mm fan and, as stated above, be semi-modular with flat ribbon cables. As for connectivity, the 650 W and 750 W will have a 24-pin ATX, an 8-pin EPS, four 6+2-pin PCI-Express, eight SATA, six Molex and one floppy connector. The 450 W and 550 W will have to settle with two 6+2-pin PCI-Express, and less Molex and SATA connectors.
The GM Series will be available in Europe as of next week with a MSRP set at around €41.93 for the G450M, €50.34 for the G550M, €58.74 for the G650M and €67.14 for the G750M.
