Early stroke cause 'discovered'  - BBC  A rare genetic disorder is the cause of some strokes in young people, German researchers have said. Scientists in Rostock found 4% of over 700 people aged 18 to 55 years who had a stroke also had Fabry disease. And strokes occurred about a decade earlier in people with the condition, the study presented to the European Stroke Congress in Brussels, found. Fabry disease is caused by a missing or faulty enzyme needed by the body to process oils, waxes, and fatty acids. These lipids build up to harmful levels in the eyes, kidneys, nervous system, and cardiovascular system.   
Power up Toshiba's fuel cell technology for laptops put to the test  - BBC  Toshiba's phase one fuel cell shows how near, but also how far, the version is from being a commercial reality. It looks like a squared-off, aluminium-cased bottle attached to a dock that wraps under a Toshiba Portege laptop. In terms of volume, it is around a litre and weighs about as much as the same measure of water. But it certainly performs well. A small, plastic, brick-shaped 100 millilitre cartridge with methanol fuel that looks like an ink-jet printer cartridge easily slots into the fuel cell body behind the laptop's screen. At the touch of the button the fuel cell instantly provides power. Toshiba says this will be enough for 10 hours of computing. A program developed by Toshiba shows exactly how much fuel is left. This is far more useful than the tiny battery mark and percentage on the toolbar. Trial tests with staff in all sorts of jobs and of all ages ended up being favourable despite initial scepticism, according to Mr Arimura. Only a few dozen people have used the fuel cells for long periods. But some liked it so much they did not want to hand it back, he said. The fuel cell is robustly constructed, despite looking so fragile.

Growing Glowing Nanowires To Light Up The Nanoworld - Science Daily  Left:  NIST "grows" semiconductor nanowires that emit ultraviolet light as part of a project to make prototype nano-lasers and other devices and the measurement tools needed to characterize them.

Nanowires made of semiconductor materials are being used to make prototype lasers and light-emitting diodes with emission apertures roughly 100 nm in diameter--about 50 times narrower than conventional counterparts. Nanolight sources may have many applications, including "lab on a chip" devices for identifying chemicals and biological agents.
