A Traffic Control System For Molecules 64

Roland Piquepaille writes "Our cells contain small protein factories which have to deliver materials inside the cell via a network of microtubules. And the transportation is carried out by biomolecular motors. Now, researchers from Delft University of Technology in the Netherlands have built a traffic control system able to force individual molecules to choose between 'roads' by applying strong electrical fields locally at Y-junctions. This traffic control system can potentially lead to new nano-fabrication techniques. Read more for additional references and pictures showing how this traffic system works."

Virtual Reality Gets Comfy 27

Roland Piquepaille writes "If you ever participated to some virtual reality (VR) experiments, you know that the environment is quite expensive and not always user-friendly. In fact, in some immersive environments, it's even possible to feel bad because of motion sickness. This is why researchers from Germany and Sweden have developed a new VR environment where the participants believe they're moving while being seated. This approach, which relies on visual and auditory illusions, could lead to commercial low-cost VR simulators in the near future."
