At the Bharat Sanchar Nigam Limited (BSNL), India’s state-owned telecom company, a message emerges from a dot matrix printer addressing a soldier’s Army unit in Delhi. ”GRANDMOTHER SERIOUS. 15 DAYS LEAVE EXTENSION,” it reads. It’s one of about 5,000 such missives still being sent every day by telegram – a format favored for its “sense of urgency and authenticity,” explains a BSNL official.
But the days of such communication are numbered: The world’s last telegram message will be sent somewhere in India on July 14.
That missive will come 144 years after Samuel Morse sent the first telegram in Washington, and seven years after Western Union shuttered its services in the United States. In India, telegraph services were introduced by William O’Shaughnessy, a British doctor and inventor who used a different code for the first time in 1850 to send a message.
A China-based supercomputer has leapfrogged rivals to be named the world’s most powerful system.
Tianhe-2, developed by the government-run National University of Defence Technology, topped the latest list of the fastest 500 supercomputers, by a team of international researchers.
They said the news was a “surprise” since the system had not been expected to be ready until 2015.

Researchers say they have created fiber cables that can move data at 99.7 percent of the speed of light, all but eliminating the latency plaguing standard fiber technology. There are still data loss problems to be overcome before the cables could be used over long distances, but the research may be an important step toward incredibly low-latency data transmissions.
Although optic fibers transmit information using beams of light, that information doesn’t actually go at “light speed.” The speed of light, about 300,000 km/s, is the speed light travels in a vacuum. In a medium such as glass, it goes about 30 percent slower, a mere 200,000 km/s.
