UK netizens may find their online activities under ever-greater scrutiny in the near future. The UK government has pushed ahead with a proposal to require monitoring of Internet usage, including social networks such as Facebook and conversations within online games.

The new UK law would require communication firms to hold records of who contacted whom, rather than the actual contents of online conversation. About £2 billion ($3.34 billion) would go toward compensating the firms for the technical challenge of collecting the data.

According to Kwabena Boahen, a computer scientist at Stanford University, a robot with a processor as smart as the human brain would require at least 10 megawatts to operate. That's the amount of energy produced by a small hydroelectric plant. But a small group of computer scientists may have hit on a new neural supercomputer that could someday emulate the human brain's low energy requirements of just 20 watts--barely enough to run a dim light bulb.

Pen and voice input for computers is so early-millennium. Now Microsoft has created a next-gen computer concept that includes touchless gestures and eye-tracking, and has taken the device on a college tour with chief research and strategy officer Craig Mundie.

In the realm of beautiful, shiny things Dell's new Adamo XPS is among the shiniest and most beautiful. And, if we were in the business of judging (note)books by their covers, we'd leave that at that. That's not our business, though; the Adamo XPS is a gorgeous conversation piece, but a computer worth $1,800 it is not.

We've come along way since the age when every office's communications nerve center depended on its switchboard operators tucked discreetly inside a windowless room somewhere. Or have we?.

Imagine running a Google search for basketball videos, and having your computer sift through actual footage of online videos rather than just the text of the descriptions. A new type of software could enable computers to run searches inside videos, and pick out humans and objects alike.
