Thermal-Chameleon Material Created
Many species have the ability to change their coloring to mimic the environment, and camouflage themselves from other animals. For longer than can be guessed, humans have also been advancing our own camouflage techniques, to protect and conceal ourselves from others too. Now researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have created a material that is able to camouflage itself from thermal cameras, and potentially more.
Vanadium oxide is a curious material that will transition from an electrically insulating state to a conducting one as it is heated. This phenomenon has been known of since 1959, but has been difficult to study because the transition could shatter large crystals of the stuff. The discovery of how to produce pure thin films of vanadium oxide though has enabled a great deal of new science, as the films are more resilient. This latest discovery takes advantage of the fact that changes in a material's electrical properties also affect its optical properties, and all of these can be manipulated by adding imperfections. This is how the SEAS researchers were able to make the coating appear to be much cooler to a thermal camera than it actually was.
While thermal camouflage is definitely one avenue many will be looking to explore, this discovery could enable many other technologies. One example would be beacons that respond to only specific infrared frequencies and another would be using a vanadium oxide thin film to accelerate the heating or cooling of a structure.

ADATA Adds to DashDrive Storage Line
ADATA has been committed to expanding and improving the DashDrive line of USB flash drives since its initial release. The latest model to be added is the UD311, a USB 3.0 device with transfer speeds up to 85 MB/s. The UD311 weighs just 3 grams and is easily hauled around on your keychain or in a bag. In addition to its low weight, it is also water and impact resistant. It will be available in capacities of 16GB and 32GB at an MSRP of $19.99 and $26.99, respectively.

Cooler Master Offering New All-In-One Liquid Cooler
Cooler Master has announced a new all-in-one liquid cooling solution, the Glacier 240L. The 240mm radiator is accompanied by a pair of 120mm fans that operate at 2400 RPM and produce 86.15 CFM of airflow. The pump, manufactured by Swiftech, pushes water through the black PVC tubing at a rate of 165 liters per hour. Also found within the radiator is a small reservoir with two fill ports for ease of draining and filling the cooler. Everything is powered using a standard SATA power connector and the Glacier 240L is compatible with both Intel and AMD CPUs. It will be available this month with pricing and exact availability varying by region.

Heinsenberg Proven Correct
There are a number of physical concepts that are often treated as laws, when in fact they have not been rigorously proven. Among these is the Heisenberg uncertainty principle, which states that you cannot measure both the position and momentum of a particle with perfect precision. Some 80 years after this idea was first suggested, researchers at the University of York, University of Turku, and Leibniz Universität Hannover have successfully proven it.
The reason it is impossible to measure both the position and momentum of a quantum particle with perfect precision is because measuring a particle affects it. Measuring one value causes unavoidable measurement error in the other. To prove this idea, the researchers considered how one measures position and momentum simultaneously. They then defined the measurement error as the spreads of the distributions of possible outcomes. Combining the errors revealed that they obey Heisenberg's original intuition.
While this work may seem the kind of stuff to remain in theoretical physics, it could have implications in quantum computing, especially quantum communication. It is the effect a measurement has on a particle that secures quantum encryption against eavesdropping, and that is defined by the Heisenberg principle.
