According to an article in New Scientist, a UK firm called Oxford Nanopore has managed to build a DNA sequencer into what looks to be an overweight USB stick. They have named the device the MinION, and it will sell for $900 later this year. It can be used to sequence DNA with as many as 10,000 base pairs in one continuous read. While it can sequence a human genome in about 6 hours, they intend the device to be used to sequence shorter genomes with tasks like identifying pathogens and screening for genetic mutations that can lead to diseases.
The company demonstrated the MinION in action recently at the Advances in Genome Biology and Technology conference where it sequenced Phi X, a virus with 5,000 genetic base pairs. A bioinformatician at Pallen Research Group stated that "Phi X was the first DNA genome to be sequenced ever" and that if it can be sequenced than much larger genomes can be as well.
In addition to the portable MinION, the company is developing a larger scale GridION for lab work that requires more processing horsepower. The sequencing technology in the MinION and GridION operate "like a tickertape reader" by unzipping the DNA using enzymes and electricity.
The article author states that the MinION and portable DNA sequencers like it are going to greatly enhance public health and medicine. When doctors will be able to carry around portable DNA sequencers, they will be able to quickly diagnose genetic issues and identify viruses and other pathogens. Sounds pretty cool (if a bit scary) to me!

At CES 2012, Microsoft announced that they would be releasing a Kinect sensor and SDK (software development kit) for Windows. In that same vien, the company is now exploring the idea of integrating a Kinect sensor directly into laptop computers.
Not the actual prototype. Just a mock up I concocted.
The crew over at The Daily managed to get their hands on two such prototype laptops with integrated Kinect sensors. They state tha the two machines resemble Asus laptops that are running Windows 8; however, upon closer inspection, the laptops have removed the typical 1.3 megapixel webcam that is common in today's notebooks and have instead placed a Kinect sensor bar at the top of the display instead. They claim that a source within Microsoft has confirmed that the two laptops are indeed official prototypes.
Unfortunately, there aren't many details beyond that. Whether Microsoft will forge ahead with this idea and license out the Kinect technology to laptop makers or if the prototypes will go into some bunker somewhere and never see the light of day still remains a mystery. Currently at $250 (to end users, OEMs could likely cut a much better deal), it is not likely that we will see a proliferation of Kinect sensors into all manner of displays for notebooks, TVs, and desktops. If Microsoft could get the cost of the technology down far enough that manufacturers could justify adding it, it could definitely catch on. In the end, I don't think we'll be seeing Kinect powered computers any time soon, but in the future when the hardware is cheaper and there are Kinect for Windows applications readily available, it could happen. Would you like to see Kinect in your laptop (insert Xzibit meme here) or desktop monitor, and if so what would you like to do with it?

You may remember Matt's review of the Lenovo ThinkVision LT1421 portable monitor from back in November, but if not it is time for a refresher from Legit Reviews. It is a 14", 1366x768 display that uses a dual USB 2.0 connection, one for power and one to drive the display, so it gives you a very portable second screen for your laptop. One discovery that Legit Reviews happened upon was Apple support; by grabbing drivers from DisplayLink, the company which designed the ThinkVision, you can use the ThinkVision on your MacBook. Check out their full review here.
"The Lenovo ThinkVision LT1421 portable monitor is a great solution for someone that needs an additional monitor on the go. With an online price of $190.67 shipped it is not something you go out and by on a whim, but is affordable for those that need it. After installing the drivers, using the the ThinkVision LT1421 was as simple as plugging the monitor into a laptop with the two USB 2.0 cables and propping it up with its photo frame stand. You can then dial-in the display to look the very best by tilting the display to the desired angle and picking the right brightness level of the 16 available..."

Introduction, Design and Display Quality
I’m a multi-monitor addict.
My addiction started many years ago. I had a rather lame customer service job, and as part of my job I needed to manage spreadsheets with customer interactions while also filling in data on a separate, large window. To accomplish this, two monitors were required. I was amazed at the efficiency of the setup, and I bought a second monitor for home use within a few months. Now, I can’t imagine using my desktop with a single display.
Laptops, however, are a different story. Multiple displays can actually be even more useful for road warriors because of the limited resolution of many laptops, yet there are issues with using multiple monitors on the road. Carrying around even a relatively small desktop monitor is out of the question, leaving few options.
Enter the Lenovo LT1421. This unique mobile monitor has a 14” panel and, according to Lenovo, it’s portable enough to be carried about with minimal hassle. Has the company managed to create a unique, must-have product for mobile productivity, or is multi-monitor use with a laptop still a concept that’s better on paper than in reality?
