Sure, iPad users may flaunt their many comic-reading apps and vivid color screens. But Kindle users can read comics too. In fact, for black-and-white comics, like The Walking Dead, the Scott Pilgrim series, or most Manga, it looks pretty good once you get the files onto your e-reader.

But a video clip seems to have captured most of the details of the device. The video from a Korean TV channel shows the Galaxy Tab as a device that [...]

A new circuit element called a memristor, or ‘memory resistor,’ could usher in extremely efficient data storage that could eventually make instant-on, low-power PCs a reality. HP is just three years away from bringing the memristor to market as a new product called ReRAM, for Resistive Random Access Memory. ReRAM can read and write memory [...]

Most textbooks are massive tomes that weigh several pounds, are printed on hundreds of pages of glossy paper, can cost upwards of $100, and [...]

You remember the saying about being as dark as a black cat in a coal cellar? Well, it turns out Canon has made a sensor that can photograph it. The new, super-sensitive CMOS sensor is fresh from Canon’s labs, and measures 202 x 205mm. A 35mm film-frame (and its corresponding sensor) is 24×36mm. This makes [...]

Olympus has revealed two new lenses today, both for the Micro Four Thirds format. One is a 40-150mm ƒ4.0-5.6 which will sell for just €330 when it is launched in October. This has a silent AF-motor for movie-shooting but is otherwise rather pedestrian thanks to those mediocre maximum apertures. The other lens is way more [...]

If you have kids, you’re going to love the Squishy Circuits Project: it involves cooking and electronics, although not at the same time. Squishy Circuits is a great sets of recipes from Samuel Johnson and Dr. AnnMarie Thomas at the University of St. Thomas, Minnesota. Essentially you will make two batches of Play-Doh, one conductive [...]
