On any given day on the World Wide Web, a lot of people say a lot of things. But when the guy who actually invented the Web takes the podium, people might be more inclined to listen. If, that is, they have access. Tim Berners-Lee – Internet pioneer, MIT lecturer, and the guy invented the World Wide Web – sounded off on a variety of issues during his keynote at Nokia World today, but one point was especially interesting: the idea that everyone in the world should be given a free low-bandwidth Internet connection “by default.”
A state-of-the-art facility aims to make desalination more efficient

By 2025, the United Nations reports, two out of three people on Earth will live in places without enough freshwater to drink or grow crops. One way to beat that trend is to extract water from saltwater. The most common method of doing that is reverse osmosis, an energy-intensive process. To reduce that energy burden, researchers are developing other methods to desalinate water, such as using biomimetic membranes. Some proposed desalination plants will reduce their energy needs by using energy-capture schemes or sustainable energy sources like wind power.
Building smart homes that are networked to run as efficiently as possible is supposed to be one of the technological fixes to our current energy consumption problem. But what's often lost in all the heady talk about innovating our way to a greener future is the fact that those wireless networking technologies also consume power, reducing the net benefit.
In a press event yesterday that required far more than its characteristic 140 characters, Twitter’s top brass – co-founder Biz Stone, CEO Evan Williams, and two of the top product development team – unveiled the new and improved Twitter. And in what looks on its face to be an attempt to lure people away from those flashy, customizable Twitter apps and back to Twitter’s Web page, the Tweeps behind Twitter have come up with some pretty cool features.
With the Space Shuttle program winding down, both NASA and several commercial ventures are developing next-gen rocket technology that will hurl the next iteration of space vehicles into the sky. But NASA acknowledges that rockets aren’t the only – or even the best – way to get into space.

It’s hard to believe, given the tragic scenario, that anyone could find beauty in such an ugly catastrophe as the Gulf oil spill, but Canadian photographer Edward Burtynysky was able to do just that in his newly released aerial images of the disaster.
Chinese workers built this country's railroad system 150 years ago, laying track for less than $30 a month in a grand effort to connect the coasts for the first time. Future railroad systems might also be built by the Chinese — or Chinese-owned firms, at least. California Gov. Arnold Schwarzenegger is hoping to spur Chinese interest in helping his beleaguered state build a new high-speed rail network.
Need to disarm an IED? Make sure you've got your Super Soaker handy. Sorry, make that your "Fluid Blade Disablement Tool."
The Stingray, the military's newest bomb-fighting tech, is a small water gun developed by Sandia National Laboratories and a firm called TEAM Technologies. Far from dousing roadside bombs with water, it uses an ultra-high-pressure water beam to slice through steel, ripping bombs open before they can harm troops. Watch below as a propane tank meets an untimely end.
Human skin is primed for touch — even minuscule pressure from a fly is enough to make you flinch. This ability does not yet extend to artificial limbs, however, and robots are a long way from having sensitive tactile abilities.
Now two California research teams have announced pressure-sensitive artificial skin made of tiny circuits, both of which could lead to better artificial limbs and helper robots.
