The Nexus 10 tablet running Android 4.2

Google has officially launched the new Nexus 10 tablet running Android 4.2. Built by Samsung but clearly designed by Google, the tablet features a very impressive 10-inch screen at 2560 x 1600 resolution, clocking in at 300ppi. Google calls it "True RGB Real Stripe PLS," and in our short time with the tablet we found it to be on par with the iPad's Retina display, with sharp text, excellent color fidelity, and great viewing angles. The Nexus 4 has a 4.7-inch 1280x768 display and uses a quad-core Snapdragon S4 Pro processor with 1.5GHz Krait CPUs, 2GB of RAM, NFC chip, and has options for either 8GB or 16GB of internal storage. An 8-megapixel camera is embedded on the back and a 1.3-megapixel camera on the front. The Nexus 4's body measures 9.1 millimeters thick, 1.5 millimeters thicker than the iPhone 5. Inside is a 2,100mAh battery that will provide a prodigious 15.3 hours of talk time, according to Google. The phone will not be able to access 4G LTE networks, and does not have an expandable storage slot. Google has stated the phone will feature wireless charging, but has not specified whether the accessories that enable this feature will be included in the box. Overall, the Nexus 10 was easily the best-feeling and best-performing 10-inch Android tablet we've seen — but whether or not there's a real market for 10-inch Android tablets is another matter entirely. Google is selling the tablet for $399 for the 16GB version and $499 for the 32GB version, which makes it $100 less expensive than a comparable iPad with Retina display. That price differential may help juice sales, but buyers will still have to contend with the anemic options in the Android tablet app ecosystem. It will be available on November 13th in the Google Play Store in the US, UK, Australia, France, Germany, Spain and Canada.

Biological Computer


U.S Scientists claims that they ave developed the world's first "biological computer' that is made from biomolecules and can decipher images encrypted on DNA chips.
A team from the Scripps Research Institute in California and the Technion-Israel Institute of Technology claims it has created the computing system using bio-molecules, Angewandte Chemie journal reported.
In the research, when suitable software was applied to the biological computer, the scientists found that it could decrypt, separately, fluorescent images of Scripps Research Institute and Technion logos. And, although DNA has been used for encryption in the past, this is the first experimental demonstration of a molecular cryptosystem of images based on DNA computing, say the scientists led by professor Ehud Keinan.
"In contrast to electronic computers, there are computing machines in which all four components are nothing but molecules,"Keinan said.
"For example, all biological systems and even entire living organisms are such computers. Every one of us is a biomolecular computer, a machine in which all four components are molecules that "talk' to one another logically,"he said. The hardware and software in these devices, Keinan notes, are complex biological molecules that activate one another to carry out some predetermined chemical work.
The input is a molecule that undergoes specific, predetermined changes, following a specific set of rules (software), and the output of this chemical computation process is another well-defined molecule.
But, what a biological computer looks like?
"This computer is built by combining chemical components into a solution in a tube. Various small DNA molecules are mixed in solution with selected DNA enzymes and ATP. The latter is used as the energy source of the device.
"It's a clear solution — you don't really see anything.
Molecules start interacting upon one another, and we watch what happens.

Sony to launch fastest XQD cards


Sony will start selling memory cards capable of write speeds of 125 Mbps from February. This will be the first cards launched under the new XQD card format.

This XQD card format utilizes PCI Express as its data transfer interface rather than SATA or PATA and can achieve extremely high read speeds and storage capacities.

These new cards address the issue of bottlenecking in high-end cameras caused by low write speeds. The amount of data processed by raw images and high-definition videos is often too much for current memory units to handle quickly, resulting in lagging video and pauses between taking a picture and the actual image obtained.

Sony has announced that the new cards will launch with 16 GB (the QD-H16) and 32 GB (QD-H32) versions along with readers compatible with USB 3.0 (MRW-E80) and PCI slots (QDA-EX1) for computers. The costs of these cards are quite high at $129.99 for the H16 and $229.99 for the H32. The readers themselves are far cheaper, at only $44.99 for the E80 and $44.99 for the EX1.

The Indonesian Mimic Octopus

A researcher shooting video in Indonesian waters captures a jawfish mimicking an octopus that itself mimics other fish.




As you saw in the above two videos, the mimic octopus is a brazen and audacious creature that got that way after it evolved a complex set of characters.

During a diving trip in Indonesia in July 2011, Godehard Kopp of the University of Göttingen in Germany, filmed a never-before-seen interaction between these two animals. In his video, we see the small and shy black marble jawfish closely following a brazen and audacious mimic octopus whilst it moves across the sandy bottom. The jawfish's markings are very similar to those of the octopus and as you'll see, it is quite difficult to see the fish as swims amongst the octopus's many arms.
