Scientists with the University of Nottingham in England recently used a 3D “bioprinter” to create a scaffold in the shape of a bone, then coated the scaffold with adult human stem cells that grew into bone tissue. The printer used polylactic acid to produce the frame for the bone, and alginate gel to cushion the cells. In the body, the scaffold degrades in about three months, as new bone tissue forms to replace it.
Audi has developed eKurzinfo, an augmented-reality (AR) app that provides information about a car’s features when passed over the console or engine.
The app debuted on the Audi A1 city car and is planned for the 2015 Audi A3. It can recognize and explain more than 300 areas of the car in German, English and Japanese, and is built on AR technology from Germany-based Metaio.
The California Institute of Technology (USA), commonly known as Caltech, recently won the Gates Foundation’s “Reinvent the Toilet Challenge” with a solar-powered, self-cleaning toilet that converts urine and waste into hydrogen and fertilizer. Loughborough University (UK) and University of Toronto (Canada) took second and third place awards, respectively.
The Caltech design features a solar panel that powers an electrochemical reactor, which breaks waste into fertilizer and hydrogen that can be stored in fuel cells. A pump sends treated water to a reservoir, where it can be collected for use in irrigation or future flushes.
Researchers from the University of Minnesota (USA) have developed a helicopter controlled by human thought. Using noninvasive electroencephalography (EEG) to record brain wave activity, test subjects view the quadcopter’s flight through an on-board camera. If subjects imagine raising their left hand, the plane turns left. If they imagine raising their hands together, the plane rises.
At 450 meters (1,476 feet), the Tower Infinity in Seoul, South Korea, will be the world’s sixth-tallest skyscraper – and its first “invisible” one. Scheduled to be completed in 2014 on a site near Incheon International Airport by GDS Architects of California (USA), South Korea and Japan, the design creates the illusion of invisibility for viewers at ground level. Cameras and LED screens that rotate, scale and merge mask the glass tower’s presence, giving passersby the illusion of a seamless panoramic environment. The level of invisibility can be controlled and only works on observers at ground level. So don’t worry – airplanes and birds should see and avoid the building.Back to top
