Whither the Wikis?

From insidehighered.com...

"Of all the Web 2.0 tools that have become de rigueur on college campuses, wikis fundamentally embody the Internet’s original promise of pooling the world’s knowledge — a promise that resonates loudly in academe.

And yet higher education’s relationship with wikis — Web sites that allow users to collectively create and edit content — has been somewhat hot-and-cold. Wikipedia, the do-it-yourself online encyclopedia, vexed academics early on because of its wild-west content policies and the perception that students were using it as a shortcut to avoid the tedium of combing through more reliable sources. This frustration has been compounded by the fact that attempts to create scholarly equivalents have not been nearly as successful.

However, academe’s disdain for the anarchical site has since softened; a number of professors have preached tolerance, even appreciation, of Wikipedia as a useful starting point for research. As the relationship between higher education and wikis matures, it is becoming clearer where wikis are jibing with the culture of academe, and where they are not."

Sustainable by design

From constructionweekonline.com...

"When the Burj Khalifa opened with a dazzling fireworks display earlier this year, the tower was hailed as a marvel of modern engineering, which it certainly is. However, it is also an excellent example of sustainability at work.

From the facilities management system that increases efficiencies and the practices and technology to extend the tower’s lifespan, to the use of condensation to irrigate its 11-hectare garden and solar panels to heat water, the Burj Khalifa comes with a ‘sustainability inside’ tag."

Generating Power from a Heart


From Technology Review published by MIT...

"A tiny, nearly invisible nanowire can convert the energy of pulsing, flexing muscles inside a rat's body into electric current, researchers at Georgia Institute of Technology have shown. Their nano generator could someday lead to medical implants and sensors powered by heartbeats or breathing."

Wind-Powered Car Actually Moves Faster Than Wind Speed, Answering Tricky Physics Question


From Popular Science...

"A California team recently tested a wind-powered car that can actually outrun the wind, adding more fuel to a lingering physics debate.

In a test two weeks ago, the car hit a top speed 2.86 times faster than the wind, according to its creators. Some physicists say this should be impossible, but car-builder Rick Cavallaro says that's exactly what happened on May 16. What gives?"
