"While 4K displays have been popping up all over the place recently with noticeably lower prices, one thing that kind of limits them all is a 30 Hz refresh rate panel. Sony is selling 4K consumer HDTVs for $5000 and new-comer SEIKI has a 50-in model going for under $1000 but they all share that trait — HDMI 1.4 supporting 3840x2160 at 30 Hz. The new ASUS PQ321Q monitor is a 31.5-in 4K display built on the same platform as the Sharp PN-K321 and utilizes a DisplayPort 1.2 connection capable of MST (multi-stream transport). This allows the screen to include two display heads internally, showing up as two independent monitors to some PCs that can then be merged into a single panel via AMD Eyefinity or NVIDIA Surround. Thus, with dual 1920x2160 60 Hz signals, the PQ321Q can offer 3840x2160 at 60 Hz for a much better viewing experience. PC Perspective got one of the monitors in for testing and review and found that the while there were some hurdles during initial setup (especially with NVIDIA hardware), the advantage of a higher refresh rate made the 4K resolution that much better."

"This article is an eye opening perspective on another side effect of power generation — water usage: 'More than 40 percent of fresh water used in the United States is withdrawn to cool power plants. Renewable energy generally uses far less water, but there are glaring exceptions, such as geothermal and concentrating solar.' The article also mentions that power plants have to shut down if the incoming water is too warm to cool the plant. 'Also, even though some newer plants might use far less water, they could find that there’s far less water available as water temperatures go up and water flows go down. Another study found that nearly half of 423 U.S. plants were at risk of lower power output during droughts because their intake pipes for water were less than 3 meters below the surface.'"

"WigWag has developed a home automation kit that combines a Linux-based 6LoWPAN router with sensor units running the open-source Contiki IoT (Internet of Things) OS. Users can add ZigBee, Bluetooth, and other modules to expand the home network, and the WigWam development kit provides shield development boards for use with Arduino and Raspberry Pi SBCs. Users control the devices with a smartphone app (initially Android-based) and associated WigWag cloud service, which lets the devices remotely respond to sensor-based events such as motion detection, rain, noise, etc. Developers can create rules-based scripts for controlling devices using WigWag's open-source Javascript-based DeviceJS development environment. WigWag used a Kickstarter page to fund production and has already tripled its goal."

RoccamOccam sends this news from the Associated Press:
"A landmark federal study on hydraulic fracturing, or fracking, shows no evidence that chemicals from the natural gas drilling process moved up to contaminate drinking water aquifers at a western Pennsylvania drilling site. After a year of monitoring, the researchers found that the chemical-laced fluids used to free gas trapped deep below the surface stayed thousands of feet below the shallower areas that supply drinking water."

"Microsoft took everyone by surprise last year with the Surface tablet. It was something completely new from the company everyone knew as a software company. However nine months later and the sheen has worn off the Surface tablet and Microsoft's financial results on Thursday revealed it has taken a $900 million write down on the Surface RT tablets, leading David Gilbert in IBTimes to estimate it is sitting on a stockpile of six million unsold tablets."
