Three years ago these same researchers found they could build an anode using viruses. Creating both the anode and cathode using viruses will make batteries easy to build. This nanoscale battery technology will allow batteries to be lightweight and to 'take the shape of their container' rather than creating containers for the batteries, which could open up new possibilities for car and electronics manufacturers."

Ars Technica has a first look at the latest beta release from the Fedora universe and it has several new shiny-bits including kernel modesetting, ext4, and faster boot times. "Fedora 11, which is codenamed Leonidas, is scheduled for final release at the end of May. It will include several new features and noteworthy improvements, such as RPM 4.7, which will reduce the memory consumption of complex package activity, tighter integration of PackageKit, faster boot time with a target goal of 20 seconds, and reduced power consumption thanks to a major tuning effort. This version of Fedora will ship with the latest version of many popular open source software programs, including GNOME 2.26, KDE 4.2, and Xfce 4.6. This will also be the first Fedora release — and possibly the first mainstream distro release — to use the new Ext4 filesystem by default.

An anonymous reader alerts us to a two-week-old story that hasn't gotten much traction in the press to date. A Japanese newspaper and the AP report that China plans to demand source code from hardware manufacturers, and ban the sale of products from companies that don't comply. China is calling this an "obligatory accreditation system for IT security products." The plan is to go into effect next May, according to sources. "Products expected to be subject to the system are those equipped with secret coding, such as [a] contactless smart card system developed by Sony Corp., digital copiers, and computer servers. The Chinese government said it needs the source code to prevent computer viruses taking advantage of software vulnerabilities and to shut out hackers. However, this explanation is unlikely to satisfy concerns that disclosed information might be handed from the Chinese government to Chinese companies. There also are fears that Chinese intelligence services could exploit such confidential information by making it easier to break codes used in... digital devices."

This extension allows you to save your bookmarks, history and passwords on Google servers, effectively giving you a 'roaming profile,' which you can sync on any computer running Firefox (and the extension, of course)."
