Overstock Planning Video-On-Demand Service
Overstock is planning to release a video-on-demand and streaming service later this year to compete with established players like Netflix and Amazon. The VOD service will boast around 30,000 titles and will be available about halfway through this year with the streaming service following shortly thereafter. Overstock is working with a third party to create original content, hoping to leverage "working with studios for over a decade." CEO Patrick Byrne described the service stating, "We think this makes perfect sense for us to get into this business. We have a deep understanding of our customers [and] know what they're looking for."

New Laser for Improved Imaging Technologies
Lasers are amazing pieces of technology that are in many of our devices, and used in the manufacture of many more. Naturally many future technologies will rely on them, but before some of them can be realized, certain issues must be overcome. Researchers at Yale University may have found a solution to the problem of speckle by using a new kind of laser.
With their brightness, lasers are ideal for many imaging technologies, such as microscopes, holography, and photolithography, but they can also corrupt the images they are being used to create. This corruption comes from speckle, which is a grainy pattern caused by the high spatial coherence of the light. In some situations LEDs can be used, as they have lower speckle, but they are also far less bright, making them a poor fit for high-speed imaging. What the Yale researchers developed exhibits the best of both technologies and is based on a chaotic cavity laser. Random and chaotic lasers normally have no known applications, but the researchers decided to work with other disciplines to see if there are any problems they could solve.
Typical lasers have a speckle contrast of 50%, but it needs to be less than 4% for full-field imaging. The new semiconductor laser comes in at just 3%, which makes it perfect for future imaging technologies that need speckle-free and bright light sources.

Quantum Dot Laser Powered by Single Electrons
I do not know how many electrons are currently coursing through my computer and monitor as I type this, but I expect it to be a lot, because that is how many it takes. The idea then that anything could be powered by a single electron seems a little crazy, because normally you need so much more. As it turns out though, it is possible for a single electron to power some systems, as researchers at Princeton University discovered, when working on how to put double quantum dots to use.
Quantum dots are semiconductor nanocrystals that are sometimes referred to as designer atoms or molecules, because their properties can be so well tuned. Double quantum dots are just two of them joined together, and they may see use as qubits in quantum computers, but first we need them to communicate with each other. To achieve this, the researchers made the dots into lasers, so that the photons they emitted could bounce off of mirrors, creating a coherent beam, and entangle each other. The laser works by having electrons, one at a time, tunnel through the quantum dots, and drop in energy as they do so, releasing a photon in the process. The reason the electrons are going one at a time is because the quantum dots can only hold one at a time.
Unlike traditional lasers, the frequency of light emitted can be tuned here, by controlling the energy levels the electrons jump between. This work could lead to new light sources in the future, and potentially more as it shows a way to control the movement of even a single electron.
