Imaging electric charge propagating along microbial nanowires Posted: 19 Oct 2014 12:18 PM PDT Physicists report that they've used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive human-made material.

Crystallizing the DNA nanotechnology dream Posted: 19 Oct 2014 12:18 PM PDT For the last 20 years, scientists have tried to design large DNA crystals with precisely prescribed depth and complex features -- a design quest just fulfilled by scientists. The team built 32 DNA crystals with precisely-defined depth and an assortment of sophisticated three-dimensional features.

Major breakthrough could help detoxify pollutants Posted: 19 Oct 2014 12:15 PM PDT A major breakthrough could lead to more effective methods for detoxifying dangerous pollutants like PCBs and dioxins, scientists say. The result is a culmination of 15 years of research. It details how certain organisms manage to lower the toxicity of pollutants.

Smartphone approach for examining progression of diabetic eye disease offers comparable results to traditional method Posted: 18 Oct 2014 09:26 AM PDT A smartphone-based tool may be an effective alternative to traditional ophthalmic imaging equipment in evaluating and grading severity of a diabetic eye disease, according to a study. The results of the research indicate the lower-cost method could be useful for bringing the service to patients in isolated or underserved communities.

iPhones for eye health: Capturing ocular images in difficult-to-photograph patients Posted: 18 Oct 2014 09:26 AM PDT Smartphone technology is a widely available resource which may also be a portable and effective tool for imaging the inside of the eye, according to results of a study. Researchers are successfully using an iPhone® application as an inexpensive, portable and effective tool for imaging the inside of the eye, including in patients who are challenging to photograph by traditional methods.

Image Guided Radiation Therapy Is Commonly Used to Ensure Accuracy in Treating Pediatric Tumors Posted: 17 Oct 2014 03:35 PM PDT Image guided radiation therapy (IGRT) is a commonly used modality to ensure treatment accuracy in the management of pediatric tumors; however, consensus recommendations are needed in order to guide clinical decisions on the use of IGRT in treating pediatric patients, according to a study.
