| Good news for nanomedicine: Quantum dots appear safe in pioneering study on primates Posted: 20 May 2012 10:39 AM PDT A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine.  |
| Performance boost for microchips Posted: 18 May 2012 10:28 AM PDT The semiconductor industry is faced with the challenge of supplying ever faster and more powerful chips. The Next-Generation Lithography with EUV radiation will help meeting that challenge. Researchers have now developed key components.  |
| Indoor navigation system for blind Posted: 18 May 2012 10:27 AM PDT A computer science engineering team has developed an indoor navigation system for people with visual impairments. The researchers have explained how a combination of human-computer interaction and motion-planning research was used to build a low-cost accessible navigation system, called Navatar, which can run on a standard smartphone.  |
| Using graphene, scientists develop a less toxic way to rust-proof steel Posted: 18 May 2012 10:25 AM PDT Researchers are making significant progress on rust-proofing steel using a graphene-based composite that could serve as a nontoxic alternative to coatings that contain hexavalent chromium, a probable carcinogen.  |
| Bright future for solar power from space Posted: 16 May 2012 06:38 AM PDT Solar power gathered in space could be set to provide the renewable energy of the future thanks to innovative research.  |
| Training the blind to 'see' using new device to 'listen' to visual informatoin Posted: 16 May 2012 06:31 AM PDT A method developed for training blind persons to "see" through the use of a sensory substitution device (SSD) has enabled those using the system to actually "read" an eye chart with letter sizes smaller than those used in determining the international standard for blindness. The device converts images from a miniature camera into "soundscapes," using a predictable algorithm, allowing the user to listen to and then interpret the visual information coming from the camera.  |
| New technique allows mass production of building components Posted: 16 May 2012 06:27 AM PDT Researchers are automating some of the processes by which computer-based designs are turned into real world entities, developing techniques that fabricate building elements directly from digital designs, and allowing custom components to be manufactured rapidly and at low cost.  |
