+ - MIT scientists reach fiber-optic breakthrough

Submitted by kcurtis
kcurtis (311610) writes "The AP (via boston.com) has a story about how MIT scientists have detailed a breakthrough in optics that could lead to cheaper, more efficient optic communications. From the story: "Like polarizing sunglasses that block light waves oriented in different directions, the MIT researchers created a clever device that splits the light beams as they pass through a circuit. The device then rotates one of the polarized beams, before both beams are rejoined on their way out of the circuit, retaining the signals' strength. But it's not just that device that the researchers are touting. They're also trumpeting the innovative method they devised to integrate the optical circuitry with electronic circuitry on the same silicon chip.""

+ - China Creates Massive Online ID Database

From the article:

Anyone can now send a text message or visit the country's population information center's website, to check if the name and the ID number of a person's identity card match. If they do match the ID cardholder's picture also appears, said the Ministry, adding that no other information is available to ensure a citizen's privacy is protected.

Completed at the end of 2006, China's population information database, the world's largest, contains personal information on 1.3 billion citizens.

Giving public accessing to the database is also designed to correct mistakes if an individual discovers that their name, number and picture don't match.

The next major breakthrough in computers will be the use of quantum technology. Then computers will run billions of times faster.
