Ever wished that you could know what a place was like before you booked a holiday or you could revisit where you went on holiday? A new virtual reality tool created by the IST project BENOGO allows you to do just this.
The project was initiated to build on research into a new image-based rendering (IBR) technique that had been carried out by the Hebrew University of Jerusalem, one of the project partners. BENOGO aimed to further develop the technologies to produce an innovative system to permit near photo-realistic 3D visualisation of actual physical places for a moving observer in real time.
IBR does not require a reconstructed geometrical model of the scene to produce the images. "By acquiring the images in a systematic fashion you can compose some images that were never taken by combining small image parts from those that were taken," explains Erik Granum, project coordinator. The decrease in the number of images needed to create a 3D experience of a place is a breakthrough in the field of virtual reality.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
