A research team led by a chemist at the University of California, Riverside has fabricated microscopic polymer beads that change color instantly and reversibly when external magnetic fields acting upon the microspheres change orientation.
The beads or "magnetochromatic microspheres" have excellent structural stability. They also are highly compatible with various types of dispersion media such as water, alcohol, hexane and even polymer solutions, allowing them to retain magnetically tunable colors in a variety of chemical environments.
Applications of the new material include display type units such as rewritable or reusable signage, posters, papers and labels, and other magnetically activated security features. The new material also can be used to make environmentally friendly pigments for paints and cosmetics, as well as ink materials for color printing. Video of rotating microspheres

The HydroPak fuel cell is a portable power generator that can provide up to 14 hours of power with a single disposable cartridge. The $20 cartridges are water-activated, and have a shelf life of several years. The HydroPak stems from a collaboration between Horizon's fuel cells and Millennium Cell's "Hydrogen-on-Demand" storage technology. The companies hope to attract consumers and professionals who currently use generators and batteries for their remote power supply needs. The HydroPak could have applications for camping, construction, emergency, and other uses.
The device, which is still in beta, is relatively inexpensive for a fuel cell product, costing around $400 in addition to the disposable cartridges. The HydroPak also has zero emissions, is lightweight, and operates with minimal noise. A water-activated cartridge can crank out 400 Watts through an AC outlet and two USB ports for 14 continuous hours.

LinuxBIOS now fully supports booting Windows. The project was accepted for the Google Summer Of Code 2007 and its main goal was to figure out how to boot Windows Vista/XP/2003. LinuxBIOS now boots Windows 2000 and XP with support for Vista soon.

The PLAICE is an open source hardware and software project that is developing a powerful in-circuit development tool that combines the features of a FLASH Programmer, Memory Emulator and High Speed Multi-Channel Logic Analyzer into one device. The project wiki is at: http://flash-plaice.wikispaces.com/ . It runs uClinux. The logic analyzer features up to 200MHz sampling rates and up to 32 input channels. The logic analyzer Java client features support for up to 200MHz sampling rates, user controlled filtering operations, time line in diagrams, transfer rates, user configurable drawing modes. The Java client supports access via almost any PC with a serial port. The Java client uses the RXTX serial library with support for 34 platforms including Linux, Windows, and Solaris. Java client plugins include an SPI and I2C bus protocol analyzer, timing analysis to state analysis conversion, and post-processing functions.
