We have previously reported on many green initiatives related to building and roadway materials: smog-eating cement, concrete that can heal itself when it detects cracks, and pavement with solar-storing technology.
Now, civil engineers at Purdue University are working to design a cost-effective mixture for road construction and bridge support.

Judy Wexler, 24, is the first woman to pilot a human-powered helicopter
More than 30 years ago, the American Helicopter Society International challenged engineers to create a human-powered helicopter that could reach an altitude of at least three meters and hover for at least 60 seconds. Sikorsky Aircraft promised $20,000 to the winner. Now, they’ve upped the award to $250,000.
In pursuit of the elusive prize, a helicopter designed by a team of students from the University of Maryland has become the third human-powered helicopter to successfully leave the ground, and the first to be piloted by a woman.

The average washing machine uses between 40 and 45 gallons of water per load of clothes. In addition, a large amount of energy is needed to heat the water. When you include the cost of laundry detergent on top of all that, you realize that washing clothes can be a pricey affair.
However, researchers at the British company Xeros Ltd have developed a new washing-machine technology that cleans clothes using a mere cup of water and just a drop of detergent.

It’s not edible, but this new fiber could be the right medicine for persistent wounds.
A fluffy new material composed of glass fibers could be the latest in wound-healing technology, say researchers from Missouri University of Science and Technology. This cotton candy-like substance (pictured above) is composed of borate glass nanofibers and has been labeled DermaFuse.

Two years ago, Air France Flight 447 was on its way back to Paris from Rio de Janeiro when it completely disappeared — without issuing a Mayday call or leaving even a trace on radar. After three search attempts, by boat, mini-sub, and sonar (in an effort to detect the ultrasonic signal emitted by the plane’s black boxes), the jetliner was finally discovered on April 3, 2011 with the help of an autonomous submarine called the Remus 6000.
