Cyber Propaganda: Pentagon report claims China ready to launch cyber-attack

The Chinese military possesses dangerous first-strike cyberwar capabilities that include special units charged with developing viruses to attack enemy computer networks, a U.S. Department of Defense (DoD) report has warned.

"The PLA [People's Liberation Army] has established information warfare units to develop viruses to attack enemy computer systems and networks, and tactics and measures to protect friendly computer systems and networks," the Pentagon's annual report to Congress on China's military power said.

"In 2005, the PLA began to incorporate offensive CNO [computer network operations] into its exercises, primarily in first strikes against enemy networks."

The report shows how the Chinese military's thinking on information warfare has changed in recent years, says Andrew Macpherson, director of the technical analysis group at the University of New Hampshire's Justiceworks and a research assistant professor of Justice Studies.

The world's first isolation hospital gives up its gruesome secrets

On average the Venetians who lived during the glory days of the Republic were rather small, just five feet five inches in height; they were well nourished, and if they lacked sugar and fat the result was excellent teeth with no cavities.

These are among the first findings of a group of archaeologists exploring a treasure trove of Venetian history that has been locked away and forgotten for centuries: the graves of Lazzaretto, an island in the Venetian lagoon whichbecame the world's first isolation hospital.

Following an outbreak of the plague in 1348, the Doge and his advisers put their minds to thinking up a way to prevent a recurrence. The upshot, at the beginning of the 15th century, was the world's first isolation hospital occupying the entire small island.

In 1630 the hospital was dissolved and the island taken over by a military garrison; later it was used to hold stray dogs. In the 1960s it was abandoned altogether.

Did a comet zap the woolly mammoths? Scientists posit huge explosion over Canada 12,900 years ago

There are intriguing new clues in the mystery of how the woolly mammoth met its demise in North America more than 10,000 years ago.

For decades, scientists have debated whether the giant, elephant-like beasts were driven to extinction by the arrival of overzealous human hunters or by global warming at the end of the Pleistocene era, the last great Ice Age. Some say it was a combination of the two.

Recently, a group of more than two dozen scientists offered a new explanation. They have found signs that a comet -- or multiple fragments of one -- exploded over Canada about 12,900 years ago with the force equivalent to millions of nuclear weapons. That unleashed, they said, a tremendous shock wave that destroyed much of what was in its path and ignited wildfires across North America.

One in five on the planet now has high-speed internet

Almost 300 million people worldwide are now accessing the internet using fast broadband connections, fuelling the growth of social networking services such as MySpace and generating thousands of hours of video through websites such as YouTube.

There are more than 1.1 billion of the world's estimated 6.6 billion people online and almost a third of them are now accessing the internet on high-speed lines. According to the internet consultancy Point Topic, 298 million people had broadband at the end of March and that is already estimated to have shot over 300 million. The statistics, however, paint a picture of a divided digital world.
