Russian plane crash kills 11

A Russian Antonov military cargo plane crashed on the border between Russia's Tula and Oryol regions, killing all 11 crew members aboard, the Itar-Tass news agency reported.

Itar-Tass cited a source from the Russian Defence Ministry's information department as saying the An-22 plane had been flying from Voronezh to Tver when it disappeared from radar screens.

The news agency quoted a Russian law enforcement official as confirming all 11 crew members were dead.

New ultra-fast, green computer

Scientists have created an ultra-fast 1,000 core computer processor which could speed up machines and make them greener.

Originally, computers were developed with only one core processor, the part of a computer's central processing unit (CPU) which reads and executes instructions.

Nowadays processors with two, four or even 16 cores are commonplace. However, Dr Wim Vanderbauwhede, of the University of Glasgow, and colleagues at the University of Massachusetts Lowell, have now created a processor which contains more than a thousand cores on a single chip.

Guitar maker Pimentel dies

Lorenzo Pimentel, whose handmade guitars are played by professionals around the world, has died at the age of 82.

Pimentel died after a long battle with prostate cancer, family members said.

Pimentel, who moved to Albuquerque, New Mexico, in 1963 with a few hand tools, founded Pimentel & Sons Guitar Makers.

His handmade classical guitars gained an international reputation after the music magazine Frets featured his work in 1965.
